CR/R! Wrap up

Jay Kimble — Thu, 21 Aug 2008 17:25:47 GMT

It’s been about a month since I took the challenge to replace ReSharper (R#) with Code Rush/Refactor! Pro (CR/R!). In that time I have adjusted well to CR/R!. There are a number of areas where I am MORE productive. Yep, I said that. There are a few things I miss (So Mark of DevExpress pay attention).

Code Analysis could improve

Code Analysis is a fairly new feature of CR/R! and as one would expect it’s not quite as strong as R#'s (I do expect this to get better, BTW). Sometimes it doesn’t find references to ASP.NET Server Controls from the Code Behind for instance which tends to make its analysis on ASPX CodeBehind files somewhat unpredictable. I also ran into some speed issues with JS code, but I think it was the network that day (because I haven’t had any issues since).

The other thing I love about R# is that not only does it analyze my code, but it gives me a convenient keystroke that helps me resolve the problem without having to leave where I am. CR/R! is building some of this stuff so we’ll have to wait and see what happens.

Embeddings

I still have a few embeddings that I would like to turn off (with no options to do so -- as far as I can tell)... I suspect I need to dig into the XML config files, but am scared to do so.

For the DevExpress Guys to note the main one I want to get rid of is called "Embed Not Parenthesis." What happens is that I’m in a long "if(...)" and I highlight the first "=" of an "==" (because I stupidly set it to "==" and not "!="), when I type "!" it translates my entry to "!(=)=" which would be nice is I had more than 1 character highlighted.

[If you don’t know what they are let me explain them. Basically with CR/R! if you have a section of code highlighted you can easily wrap that selection with say a region by typing CTL+3 (BTW, # = Shift+3 so the sequence makes sense); when you do that a #region/#endregion automagically wraps your selected code and drops you on the line to set the region text. ]

The embeddings in general could really benefit from a different set of key sequences. it’s too easy to highlight a section of code and accidentally type the single character that creates the embedding... I’d prefer a CTL sequence. Yes, I know I can change them myself, but the defaults make the product frustrating for newbies.

Wish List

Beyond what I have already mentioned I really have 1 wish. I want either an alternate set of keystroke shortcuts for things like Embeddings and single character templates [CR/R! has some single character templates that you type like "c{space}" and a class shell automagically appears] that I can set as the default (so choose something other than what has been the standard) or the ability to package up my settings and be able to easily share them...

Yes, Rory, I have thought about contributing an addin for your community project.

Script# Compatibility

BTW, CR/R! works with Script#! Well, I ran into a few minor difficulties, but I could use it with the product which is all I would have asked for. No crashes, and no real warts.

Final words

Well, the good news for the CR/R! crew is that I’m a convert. I waited too long for VS 2008 from R#, and in that time I realized that there is a different place to go to.

Finding that I can refactor all kinds of things (like HTML code and JS code as well as C# and VB code now if it only did Python... just kidding, Mark... I don’t need it) really sealed the deal.

If you are trying out CR/R! you should get the Rory’s latest zip file containing all the community plugins. You should especially install "Refactor_Resolve" from this zip file (You’ll want it!). This is the plugin that was written by Koen Hoefkens. BTW, these plugins I think all run with DXCore, so if you don’t have a license to any kind of Refactoring product then you might want to consider installing DXCore (it’s free) and then installing these plugins... they can make your life a little easier.

Red Gate & Reflector: My Concerns...

Jay Kimble — Thu, 21 Aug 2008 13:22:20 GMT

Ok, before I start off I want to note that Red Gate is one of our "Friends of TRT," so they show up on just about every page of the site (and would appear in every RSS if I had the time to figure out how to do it). I also want to note that I know that I am breaking a rule with this post and may alienate a vendor, but this needs to be said (and sometimes I can’t resist).

I love Red Gate tools. Their commercial stuff is absolutely awesome, and I mean that. If you don’t own at least their SQL Data/Compare tools, then you should. Their software engineering is without much fault (as far as I have seen). I love how they help the community (hence they are in our "Friends" program).

I was chatting with JP (John Papa) when I caught the news in the latest bulletin from them (it might have been old), and went from casual talk about John’s skin on his blog (see here) to "Crap! Red Gate just bought Reflector..." JP doesn’t necessarily agree with me, but I wanted to at least spit out what I’m bugged by.

Red Gate also owns the PInvoke.net addin for VS2005 (and maybe it now works with VS2008). When you click on the web site to get the addin you are prompted for an email address and are informed that you will be getting ANTS Profiler 3 and Exception Hunter 1 as well... so they bundled 2 trials with a free product... products that you may already have licenses to.

Not only that but every couple days you start getting spammed by their marketing department (it’s one of those... 2 days, 5 days, 1.5 weeks, 3 weeks, and after about a month they finally leave you alone). The bigger problem is that they don’t check their DB to see if you are already a registered licensee of a product (beyond the fact that you went there for a FREE PRODUCT).

So everyone is wondering if .NET Reflector will continue to be free. I know that it will... It will just be bundled with some stuff that you may or may not want... and then you’ll be marketed to for a couple weeks after... That would be my big complaint. I hope that they choose to do otherwise (right now you can still download just .NET Reflector... but the marketing guys haven’t had time yet to figure out what they want to do... so we’ll see what happens).

BTW, I hope I’m wrong about all this ... I really do. Red Gate is a company I really do like (I just don’t always like the way they have handled "free" products in the past)... I hope they continue to have a single download to the free product.

Review: Gurock SmartInspect

Jay Kimble — Tue, 12 Aug 2008 14:10:27 GMT

About a year ago, I was blogging at CodeBetter and I was given a product in hopes that I would review it. In fact I had won a copy of this product in the past. I promised and promised that I would take a look at it, but I never got around to it.

Mainly because I didn’t have a use (or thought I didn’t have a use) for a logging product at the time. Logging isn’t really all that "sexy" and I was trying to dive deep into all kinds of things.

Well, with my day job we ran into a some problems that after I analyzed the errors I realized that I was missing an important piece of the puzzle... So I started thinking about what I might need. Enter that product that I hadn’t had a chance to review...

Logging isn’t "sexy" or is it?

It’s only "sexy" when you NEED it. And when you need it you need something good. SmartInspect is really, really cool, and IMO after finally taking a day with it, I can say it’s also "sexy." It really brings your logging to life.

I’m an ASP.NET guy, so what I need is to be able to track a user through a site and see there path up to the error. SmartInspect allows you to create "sessions" of logs that follow a user via their session. You can also use a default session (if you are using something more single-processed/threaded).

You can colorize different things in the log and can even see the properties of an object that you throw into the log (you simply tell it to log the full object passing just the variable).

The best part for me was it was pretty simple. I did a fairly advanced thing with it in relatively short order (Sessions, logging our SQL calls), and it really wasn’t that much work. The code that you have to inject into your app (yes, you have to inject code into your app) is pretty trivial.

Remote Logging viewing

What I really liked was that the SmartInspect log console feels like VS and is a TCP/IP server which means that you can point an app at a machine to log via TCP/IP. The version that I was given even included source for the logging library (and I think everything else). Yes, you can log to a file and other more traditional log destinations... but the TCP/IP server is so "sexy."

Sold

Anyway, my workplace will be purchasing a copy of it... and it’s a tool you’ll probably need at some point. Here’s the web site (go check it out for yourself) - http://www.gurock.com/products/smartinspect/

BTW, it’s for Delphi, and Java, too.

DLRScript 0.55 released for Silverlight2 Beta2

Jay Kimble — Thu, 24 Jul 2008 20:12:15 GMT

[UPDATE: I forgot to add the link to the project - http://www.codeplex.com/dlrscript/]

It took a bit of time for this release. In the end I had to take everything a step back (as well as there are probably a few "mid thoughts" in here as the release of SL2 Beta 2 caught me a bit by surprise... actually the changes to the DLR caught me more by surprise).

The step back is that we no longer get script code lines when there are issues. I’ll try to bring this feature back, but right now if it breaks, you’ll know it via an alert with a .NET error.

Future direction
I need some feedback on this. I’ve been thinking about scrapping any attempt at jscript compatibility and am thinking more about ecma3 support (DLRJScript has an ecma3 mode). The benefit there is that I could start focusing on building a better set of client-side APIs instead of a more compatible one. That said, I’m not sure how qualified I am at coming up with a "better" set of client-side APIs.

I do want some feedback though. Let me know what you think: jkimble-at-gmail.com.

Tampa User eXperience (TUX) User Group is coming September 10th, 2008…

Jay Kimble — Fri, 18 Jul 2008 03:35:18 GMT

I am proud to announce that I and a couple other guys are starting User Group that revolves around User Experience (or UX) in the MS tools eco-system. The other guys are Shawn Cady, Perry Panagopoulos, and Bill Reiss (MVP) [Bill always gets his MVP props].

I could give you all their backgrounds, but I’ll make them do it at the first meeting. I’m sure Papa Fish (aka www.devfish.net) the local MS Dev Evangelist (my Blog Father) Joe Healy will be around (at least for the first meeting).

TUX' Focus
Our focus will be on the "now" of Ajax and how it integrates with ASP.NET (in all its various forms), and the "future" of Silverlight2, and anything in between (like adding Silverlight2 controls to Ajax sites, etc); we’ll not be stuck in just Web either... we’ll probably do some WPF as well. We’ll also be dealing with some of those more abstract things that you need to get better at (like how to be a better designer, creating good user experiences, etc.), and we will do our best to keep this group "devsigner-friendly" (devsigner is a developer who is also a designer).

We have a lot of really creative ideas to make this fun and useful to you today as well as with an eye for the future (but I don’t want to blow them all)... We will definitely keep this interactive and will try to help you solve your problems as well (at least we’ll be around to chat with you before and afterward).

First Talk: Intro To MS Ajax Scripting
The first person to present will be me. I will be pulling a talk out of my paid pile which means that you have probably never seen me give this talk (unless you work at one of the companies I gave it at)... this is very special and will never be repeated (well, maybe). This talk is one that I have yet to see anyone give (for free). It’s an introduction to the MS Ajax scripting framework. Oftentimes you see a demo where someone shows you how to build an Ajax Extender control where a JavaScript is thrown in, but rarely (I’ve never seen it done) does someone talk to you about building the script behavior which is used to create the Server-Side Extender (I will in fact be doing just this). You will leave this talk with the knowledge of how to do it. As is often the case when I talk about JavaScript, I’ll end with a Script# demo which will make your life a lot easier (so we’ll build the last demo in C# which will be compiled to MS Ajax-style JavaScript); this big demo is a selection grid behavior that I built for my employer to replace a commercial grid component that we were using; you’ll definitely have a use for it.

Bonus
We’ll have Pizza provided by Answers Systems, so just get there after work... you don’t need to eat first.

AND!!!! Bill Reiss (MVP) has graciously given us an MSDN Premium Subscription (used to be MSDN Universal) to give away, so don’t miss it.

Where/When will it be?
We will be holding these events at my workplace: Answers Systems in Oldsmar, FL. Better directions than this will follow in the near future (we will have a web site soon), but it’s right next to (West of) the Oldsmar Fleamarket on Tampa Rd (aka Hillsborough Ave). We plan to open the doors at 6:30pm with the activities starting at 7:00pm.

Can’t make it, but you really wanted to see my session?
<sarcasm>So you are in my fan club (Eric Wise, I know that’s you since you maintain some of my stellar code), but you live in another state (like say the cold state of Ohio... where it’s 40 degrees Fahrenheit in August) so there is no way you could see this session by me, but you really, really want to see it, but the plane ticket is so expensive.</sarcasm>

Well, we plan on videoing our sessions and making them available online (as long as the speaker is OK with it, and I am... SO this is the LAST time I’ll be able to charge for this session... unless I revamp it which I will).

Afterwards...
I’m not Joe Healy so I can’t pick up the tab, but there is a Starbucks down the street that many of my colleagues and I like to frequent (Stimulants... I need a good stimulant not a depressant... but we could be talked into depressants), so don’t be surprised if we all end up somewhere afterwards or maybe somewhere else...

RSVP
If you plan on coming please drop me a line via the contact form on this site. We need this to help us figure out how much Pizza to buy.

PS
In October (the 2nd Wednesday), Bill will be doing a Silverlight2 talk (He’s a Silverlight MVP and a soon-to-be Silverlight book author). It will be more of an intro, but he plans on really giving a nice overview from both the diesgn standpoint and the development standpoint.

And, yes, we actually have a a list of things we’re thinking about for November... nothing definitive (yet), but we plan on being way ahead of the game (as best as we can).

An Answer to my post for young programmers

Jay Kimble — Wed, 25 Jun 2008 01:15:35 GMT

My good buddy (actually my best friend from High School), "The Witt" complained that I wasn’t being helpful to programmers who are trying to learn the craft when I posted two weekends ago on "A Question you should ask when hiring a non-entry level developer." (OK, he wasn’t the only one... but, hey, we have a history, so he can get me to post a response, and you can’t... deal...)

I decided that our subsequent conversation in email would make a good followup post for those who want to know what they should be doing, and with his blessing I am posting an edited version.

[It started with this comment]

The Witt - OK I know that I am new to the ASP codeing info.
I understand the security issues ( or at least, what might happen with leaving every thing wide open). BUT, Having just completed two semesters of nothing but ASP I just don’t see what wrong... I AM NOT a seasoned programmer...and my classes taught us to connect inthis very manner you discribe...
can you eleborate for those of us that are trying to learn? show us what you would do instead?
thanks in advance

Jay (in Email now)- I know I probably made some harsh statements there (in my blog post). I meant it to be hard, but it was as much about seeing some consultant coming in and writing crappy code against my APIs and leaving HUGE security holes in my website.

The major point is for ASP.NET that you should always use Command objects with parameters... something like this (code may not compile cause its off the top of my head... there’s probably an error in there somewhere...)

        1: Dim query as string = "select field1, field2, field3 from someTable where ID = @TableID"

       2: Cmd.CommandText = query

       3: Cmd.Parameters.Add(new DbParameter("TableID", cbo.Value)

       4: ' Code continues....

The trick is in using the "@" variable in the query, and using the Parameters collection. When this gets shoveled down to the database it gets sent differently and if someone tries to change that "cbo.Value" within the http post by trying to add their own SQL it will fail.

I know that changing the variable in the http post statement sounds advanced... go here --> http://www.bayden.com/TamperIE/, download the TamperIE tool (for IE) and try it out... You’ll see that you can in fact force whatever values you want into the post.

As far as other dev environments go (I know you deal with a couple others), you want to figure out how to send a prepared statement to whatever SQL Server you are dealing with (ms access has these as well, so does Oracle and everything else I can think of... even the free PostgreSQL has them).

Anyway, I see you as someone who’s growing as a developer... you’d not go into an interview and present yourself as more than you are... that too is the problem...

Do you mind if I post this (more or less?) as a new blog post?

The Witt- I don’t mind in the least…

Like I said I am trying to learn. The “@” tucked in front… I always thought that was just to get the info from the current page. It’s nice to know what that really does. I do use that for most of my sites. I just never knew all the reasons.

I think that is the problem with a lot of the schools today. They are just pushing the students out and they really don’t know what they are doing. (Not that I always know what I’m doing).

---------------

Ok. it’s not all that edited. One more thing I forgot to mention. If you use an ORM or something that builds classes for you, then you probably are getting this type of functionality (just about every ORM I know of uses prepared SQL statements to push data). My favorite ORM is SubSonic (and I know others rave about NHibernate)... It the Java world I use Apache Cayenne (and people rave about Hibernate over there)

---------------

BTW, I take great pleasure in mentioning that The Witt turns $28 (that’s hex) in a little less than 2 months... unfortunately I turn $28 about 2 weeks before him.

A Question you should ask when hiring a non-entry level developer

Jay Kimble — Sat, 14 Jun 2008 13:18:23 GMT

And I mean every developer. If you are an entrepreneur and you are hiring a consultant to work on your hot idea you need to do this. It could cost you everything if you don’t.

I recently took on a side project. It’s a return to a project I did 2 years ago. Since I have worked on it there have been at least 2 other people on the project. I’m writing this for the Business Development guy (the guy I assume hired the other folks). I am not writing this to "cut" on the other developer (I am not perfect), but I did detect a flaw that for me is critical. So one of the other guys is not only not up to snuff IMNHO, but s/he shouldn’t be working anywhere as anything but entry level (I’m sorry to be so harsh, but when you understand what I’m talking about you’ll why I’m being so harsh).

One more thing because I’m writing this more for a non-technical person. You don’t need to pretend to be technical. Pretend like you’ve hired someone to help you assess a programmer, and this is your one and only question.

The Question

When should/would you ever right code like the following (pick the version that applies to you):

        1: // C# Code

       2: string query = "select * from SomeTable where SomeID = " + cboField.SelectedValue;

       3: SqlCommand cmd = new SqlCommand(query, connection);

       4: SqlDataAdapter da = new SqlDataAdapter(cmd);

       5: da.Fill(ds);

       1: ' VB.NET (actually most versions of VB look something like this)

       2: Dim query As String = " select * from SomeTable where SomeID = " + cboField.SelectedValue

       3: Dim cmd As New SqlCommand(query, connection)

       4: Dim da As New SqlDataAdapter(cmd)

       5: da.Fill(ds)

       6:  

       7: ' Thank you Telerik for the quick translation

The Answer

The simple answer is nowhere.

The biggest reason is security. That code enables something called SQL Injection. There are utilities that exist that will let a hacker (actually you as a non-technical person could use them) to steal your entire database via a single whole in your app like this. All kinds of bad things can happen as a result of this. I recently switched grocery stores because my old grocery store had an IT problem where my debit card number got stolen. That kills it for me. I won’t be going back. The same will be true of your customers (if you don’t get sued). So the proper answer to this question means a lot.

A second option is that the programmer might mention the DataSet. This is really less critical (and there are times to do this). The first line of the code is what should be singled out in your mind, because this will tell you if the programmer "gets" security. If s/he doesn’t understand it here... s/he probably won’t understand it elsewhere (you probably have a non-professional programmer pretending to be a professional programmer... take this from a guy who started as a non-professional and doesn’t have a programming degree).

If they suggest making any changes to the first line, then they know what the problem is. They pass. If they leave that first line alone. They fail. By the way, it doesn’t matter whether the programmer is building a web app, a windows app, or some kind of service, this is a universal mistake.

No matter how cheap they are they are creating problems that you don’t need. You can get a good programmer for a lower rate. For instance, I lowered my rate considerably to get a small piece of the pie on the app I’m working on.

To Cache, To Static, or To Session "When?" is the question

Jay Kimble — Tue, 10 Jun 2008 15:15:35 GMT

DonXML has an interesting article over here that got me thinking about a technique I have been using for years now, and I’m not sure I’ve seen much written about it.

The basic tenet begins like this: I avoid session like the plague (not sure why except I have visions of some abuses I have seen... like full DataTable’s stored in session). The only time and I mean the ONLY TIME I use Session is if I have a value that needs to be associated with a user across the WHOLE site. As a result I really try to design my model where there are minimal values that need to be associated with a user site-wide.

What I have seen is that values come in 3 basic variations as far as Web site variables go: Values associated with a user everywhere, values associated with a user necessary for a few pages, values that really are application level values.

My suspicion about "Values associated with a user everywhere" is that they are not as prevalent and are often the result of programmers either not fully understanding web apps, they just aren’t thinking things through, or they are pushing a value into session site-wide when they only need it in a couple places. Treat Session like you do ViewState: it is a snake (maybe a poisonous one) that while necessary to kill the rats in your back yard due to the citrus trees, you don’t want a dozen snakes in the backyard either... Only use the number of snakes that you need (if you have no rats then 0 is the perfect number of snakes). So the lesson here is to really look at your user-related values: determine if they really are used everywhere, and determine if they need to be available in memory the whole the user is on the site.

For values associated with a user necessary for the a few pages, I tend to use cache, or I do use Session (but I clean up immediately after I’m done). When I use Cache I factor in the user’s Session ID. The thing I like about Cache is that I have a much richer set of expiration options. Session sticks while a user is clicking around the site... Cache let’s me absolutely set an expiration time. I also am aware of the fact that Cache can be unloaded early (so I use Cache as a temporary place for a value knowing that I may need to retrieve it again). If it’s something that isn’t stored elsewhere then into Session it goes (even if I have to delete that Session var later). It’s really about managing the data in memory.

For the application type values, I usually forget about the whole Application mechanisms (you might use them, but I do something else), I like to use static/shared values on individual classes. This has the effect of better organizing your code (and if you do any else with the class it simplifies things... I suspect some automated test guys would agree with me on this point). Why mention these here? Well I have seen my share of things that were really application related or indexed application related (such as storing this customer’s company info in session... that really should be either a cache or a static, and it should be retrievable by some company id).

Don’s post was originally spawned by the new Velocity cache from MS. Honestly the only comment I have on it is that I wish they had chosen a different name. I hear Velocity and I think about the text template engine (the one for Java... but the one for .NET is nvelocity)

Papa to write Silverlight2 book

Jay Kimble — Fri, 16 May 2008 17:38:19 GMT

My buddy JP (John Papa) is writing a Silverlight2 book. See his blog here and here for more info. JP is known for his DataPoints column in MSDN magazine (and he is an MV, a former co-worker, and former co-blogger... SO, I read his blog).

I found this out a day after I visited the Manning site and purchased to EAP Silverlight2 books. I wish I had known I would have seen what I could do to purchase an early release of JP’s book.

Needless to say I expect John’s book to be really good. I know that he’s an awesome communicator, and has been heavily in this whole XAML space for a while.

I won’t write about my newly-purchased Manning books yet (especially since this is a post where I push John’s book).

Silverlight2 Programming: The Designer Rule

Jay Kimble — Tue, 13 May 2008 16:04:43 GMT

I’m starting a new series on Silverlight2. I am currently building a little SL2 prototype, and as I am learning things I thought I would write them down here.

The first rule deals with working with Designers. It is stated as such.

"Prefer XAML code to CLR/DLR code when it comes building interfaces"

Note the word "prefer" here. That word means "usually", "normally", or "unless there is an exception."

This is best explained by some C# code I saw the other day. It looked something like this:

        1: string ElementX = @"<div class='twocolumndiv'><span class='singlecolumn'>{0}</span><span class='singlecolumn'>{1}</span>";
  

The problem with the above code is that you’ve embedded it into your code. It’s effectively buried. If someone else needs to change this template to say add a field or to make changes in any manner, they are scanning the code looking for this (provided they know where to look); this will be the cause of much swearing and maligning of your name.

To make matters worse, if you have a web designer you have effectively removed their visibility to this code (maybe this point is made a little sharply; I know some web designers who would be scanning the code as well, but they wouldn’t be happy).

So how does this relate to SilverLight 2? Simple, you should try to avoid instantiate controls on your Silverlight views (pages??) that a designer has no visibility to (in other words, using a UserControl that has an associated XAML is fine, but instantiating a new UserControl and throwing a new layout and a bunch of text boxes should be done with great care... you should know why you did it that way).
