Impact Of Selected Target Frameworks?
Jul 26, 2010
In Visual Studio i can select the target .net framework version, which for example defaults to 3.5. Now when i build my application with this setting, i guess it wont work on computers with .net framework 3.5 not installed, right?But lets say i choose .net framework 2.0 as target .net framework. Will my application work on computers that have .net 3.0 or .net 3.5 framework installed, but not 2.0?In other words: Is the .net framwork always backward-compatible?

c# - Does queuing threads impact non-thread safe objects in the same class?

If I spawn a thread with ThreadPool.QueueUserWorkItem and that thread does not reference the object that is not thread safe, would it compromise that non-thread safe object? By not thread safe object, I mean a third party interface to a programmable logic controller that has no ability to open simultaneous connections or concurrency support.I suppose I just wanted to be sure that by queuing threads in the same class as my reference to that object, I wouldn't somehow be compromising its thread safeness in a way I didn't realize.

I have created an exe file by compling on vb. However finding that not all systems like it and .net framework & isnt as compatible as you first think. I have create an application which doesnt use "imports" to reference anything. I compiled it in .net framework 2.0. It didnt work on XP machine which had .net Framework 4.0 got runtime error. Is there anyway making the compliled .exe available for all frameworks or am I going to have to create an .exe for each .net framework to encompass all versions?? Does it have to use .net framework at all depending on the application?

What's a good way to define what the Framework's are?Basically I'm looking for a good way to give a brief overview of what the .Net Frameworks are and why an average person should have them installed.

I have 1.0, 2.0, 3.5 and 4.0 framework versions installed but when I edit/upgrade existing .NET applications, how can I target newer frameworks? I am using VS 2005. But I also have 2008 and Beta 2010.

I know this question has been asked before, but none of the existing SO questions provide an adequate answer for my specific case.
I'm the lone developer working on a project mostly during free time. I'm approaching 100 classes so far, and I'm starting to realize that testing that many classes is becoming daunting. Especially as I go back and add in operator overloads for =, <>, CType, and Not; implement IComparable(Of T), IEquatable(Of T), IEqualityComparer(Of T); and overriding base methods like Equals and GetHashCode.
My current testing method has been to randomly scribble out some Debug.Print code for a specific class/method on a dummy form behind a single button, run the project, click the button, and make sure the Debug window has my expected value. But this is both tedious and starting to become a time waster.
What I know that I need to do is for each and every class, draft up a set of tests specific to that class to test its functionality. So I go and look at testing frameworks like NUnit, Gallio/MbUnit, etc. But I really don't see the value in them. It so far seems that I could just write a dedicated test class for each implemented class, wrapped in #If DEBUG/#End If blocks, and link those to a bunch of buttons on a large form to run my tests.
But that could take weeks at my current rate. So I ask SO for their opinion on how to approach something like this. Am I better off figuring out how to integrate one of these open source testing frameworks into my project? Or should I just write a bunch of testing classes and output their data somewhere?
I use VB Express 2010 and VS 2010, depending on which computer I'm on so I'll need to be able to do testing in both.

I'm using the x86 target CPU setting (and .NET 2.0 as target framework if that's important) for all of my projects and components. This worked without any problems with Visual Studio 2008. My developer PC uses a x64 version of Windows 7.But now I have a new project in Visual Studio 2010 where both, the main project as well as the user control component is set to x86 target CPU, but I still get following error when I try to run my main project with the user control placed on the form:
"Could not load file or assembly 'XXX' or one of its dependencies. An attempt was made to load a program with an incorrect format."
This is the normal message e. g. if the main project has a target CPU of "Any CPU" and the component only "x86", but in Visual Studio 2008 it worked fine if I set both to "x86". Why this is not working in Visual Studio 2010 anymore or what I need to change that it works again?

I just installed Visual Basic Express 2010. I am doing a project at the moment for college. The project is running fine on the computers at college. But when I try to run it on my home PC I get this error message.QuoteWarning1: Possible problem detected while building assembly 'StockSYS': Referenced assembly 'Oracle.DataAccess.dll' targets a different processor..I have Googled it but when I go to the advanced compiler settings, there is no option to change the target CPU, just an option to change the target framework. I know that this has something to do with trying to run it on a 64-Bit OS. I just don't know how to change the target CPU.

I need a function which can determine the target website of a *.url file.
Currently I develop a web browser. When you drag a file onto the exe in Windows 7 or pass a URL as a parameter to it, it will open that file/website (at least attempt to). I will fix this code and make it only open files that has HTM, HTML, LNK or URL file types, maybe also some picture files and similar as well. Here is the code I currently use to detect the command line parameter:
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
If Command() = "" Then

My VB.NET 2010 app currently targets .NET 3. I have to update it to target .NET 4 to get around some Locale / CultureInfo issues. What's the difference between .NET 4 Client Profile and the other .NET 4s I have on my machine: Extended and Multi-Targeting Pack? Which flavour of .NET 4 should I target? I want to target the flavour that the average user running Microsoft Office (Excel/Word/Outlook) out in the wild is most likely to already have. Why (on my machine) is there only a regasm.exe for v2.0.50727 and v4.0.30319? Why not a separate version for the other versions installed on my machine? (3, 3.5)

I am currently trying to read the target line of a shortcut file, if you were to right click and view properties of a shortcut, you can see the target line which holds the path of the file for execution. I problem is the target lines have attributes/properties at the end of the target line. The code i have atm reads everything except the most crucial part, the data after the .exe.. For example
Say i have a shortcut file whose target line(if you view properties of the file) is as such:
\adminappsVbNetSQLScriptRunner.exe AccountNumberUsage
My current program reads in this part of the target line..
\adminappsVbNetSQLScriptRunner.exe
But i need the last part, its the whole point of the program...why it stops reading when it hits the .exe or how to make it continue till end of the target line. I eventually store each target line returned into an array which ill export to excel later on.The code used to retrieve the target line is below.
Public Function GetTarget(ByVal dt As System.Data.DataTable)
Dim path(dt.Rows.Count - 1)
Dim wshLink, strPath, wshShell
Dim rc As Integer = 0

I recently wrote a quick VB.NET app that injects a DLL into a running process. To test it I was creating my own vb.net Class Library project which simply spawns a "Hello World" message box in hopes of it showing up in the target process once I injected my HelloWorld.DLL.My problem is that the message box never shows up after I inject the HelloWorld.DLL. I'm pretty sure the reason for this is because once my HelloWorld.DLL is injected (since it's a VB.NET DLL) it does not have a DllMain and hence has no idea what to execute and nothing happens.

I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:
Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString()
Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)
If Not (myOrgName Is Nothing) Then
