Make Property Required / Catch At Compile Time?
Sep 2, 2011[code] i get an app error when running the app, because i didn't set the ID.I was wondering if there's a way to make sure the programmer assigns all properties in the class,and fail at COMPILE TIME rather than have to catch the error at runtime...
View 2 RepliesVariable Declared Inside A For Loop - Make This To A Compile Time Error?
Mar 27, 2012Today I investigated a logical bug in our software and figured out that this is related to the way VB.NET thread variables inside a loop.Let's say I have the following code:
Dim numbers As New List(Of Integer) From {1, 2, 3, 4, 5}
For Each number As Integer In numbers
Dim isEven As Boolean
[code]....
The problem is that isEven is declared but not assigned.In this specific case, it would be correct to write dim isEven as Boolean = false but I haven't done this.In VB.NET, a variable that is declared inside a for loop keeps its value for the next itaration. This is by design: [URL]but this is also dangerous pitfall for programmers.
However, until now, I haven't been aware of this problem/behaviour. Until now.Most of our code base is C# anyway, which doesn't allow the use of an uninitialized variable, so there is no problem. But we have some legacy code that is written in VB.NET that we have to support. So the best thing would be to generate a warning or even an error in this specific case.But even with Option Explicit / Option Strict this does not generate a warning / an error.Is there a way make this a compile time error or maybe a way to check this with FxCop?
IDE :: Linq Causing Run-time Compile Error But No Compile Error In VS2008?
Apr 20, 2009I have a Linq-to-SQL class diagram in my web application containing the two tables in my database (held in a DBPro database project in the same solution). All was working fine yesterday. I start doing some work tonight and note that the solution compiles fine in Visual Studio, but when I run the web app I get a compilation error:

C# - Compile Date And Time?
Aug 14, 2009Is there some clever way of getting the date and time of when the dll was built/compiled?
I'm using the assembly version numbering and reflection to retrieve and display this info when the app is deployed. But in some scenarios it would be more convenient to know when then dll was actually compiled rather than the auto incrementing version number. I don't think the modified date on the dll file itself is reliable due to the way the app is deployed.
Dim assemblies = AppDomain.CurrentDomain.GetAssemblies
Dim assemblyName As String
Dim assemblyVersion As String

View 1 Replies.net - Design UI Dynamically Or At Compile Time?
Nov 28, 2011I want to have a bunch of different screens, yet I don't want to have to use 20 different forms (I'm pretty sure that's bad practice anyways), and I don't want to lay down all the controls at once in the designer because then things get messy. I had an idea of running a sub on startup that would dynamically generate all the controls I need with all the right coordinates and settings, and then dump al the ones needed for a specific screen into a Panel. Then I return an ArrayList of panels, and pull out the correct panel to attach to the form when I need that screen. The only problem is that my form will not have any implicit knowledge of its controls, so I'm assuming I wouldn't be able to use the WithEvents / Handles. keywords to declare handlers in the form class (which is what I'd rather do).
View 3 RepliesVS 2005 Run Code At Compile Time?
Oct 13, 2010I've been building tools for ArcGIS. Part of ArcGIS is toolboxes which is basically a collection of tools bundled together. I know how to make toolboxes, but the code I have runs within Arc itself - ie. currently it only runs when you actually start Arc up and run a tool which makes the toolbox.
In theory the code should be able to run outside of Arc and ideally I want it to run at compile time. I know you can run executables as pre and post build events when building the installer so I was thinking I could make it build the toolbox as part of one of these. Catch is, the executable code would need to have access to the compiled files of my project (it needs a link to each tool to build the toolbox) so I can't make the executable in a seperate project. The current project is a class library. Is there a way to run code within my project when building the installer?
C# - Conditionally Hide Properties At Compile Time In .Net?
Oct 14, 2010Depending on a preprocessor directive, I want to set all properties in a class to EditorBrowsableAttribute.Never.
I thought about creating a custom attribute, derived from EditorBrowsableAttribute, but unfortunately that class is sealed.
I've had a look at ICustomTypeDescriptor, but in the GetProperties method, I can get hold of each property descriptor, but the attributes collection is readonly.

View 1 RepliesForce A Compile-time Warning / When Using An Unassigned Local Variable?
Nov 15, 2010Today I discovered that something I had assumed about VB.NET for many years was not true (worrying!). I assumed that a variable declared within a loop had a lifetime of the iteration it was declared in, but in fact it seems it has a lifetime of the whole procedure.[code]I had assumed an output of False, True, False, True but instead it is actually False, True, True, True..In C# the equivalent code would not compile as you would get a compile time error of Error "Use of unassigned local variable 'var1'".I realise there are many ways to fix this and that best practice would be to declare the variable outside of the loop and reset it at the beginning of every loop through.I find this behaviour so counter-intuitive to me that I would like at least a compile time warning in VB.NET when/if I do this. (I could also then set this on any projects I already have and get warning that would allow me to check that my assumptions aren't causing errors).Does anyone know how/if I can get this to generate a compile time warning in VB.NET? Am I the only one that finds this counter-intuitive?

.net : "Statement Lambdas Cannot Be Converted To Expression Trees" Compile Time Error

Protected Error In Compile Time, When No Protected Class Is Used?
Nov 10, 2011Dim box As MultiTextBox = New MultiTextBox
Dim i As Integer
for i = 1 to 3 Step 1
lengthWidthHeight = MultiTextBox.GetItemValues()
Next i
This excerpt of code is using the NXOpen API. In the NXOpen API, the MultiTextBox class is public. However, when I compile the code I get the message:
'NXOpen.UIStyler.MultiTextBox.Protected Sub New(ptr As System.IntPtr)' is not accessible >in this context because it is 'Protected'
My question is, how am I getting an error about protected scope? Could it also be that the API documentation is incorrect?
