Problem: A 2 year old solution made in VS2010 with vb .net 2.0. We are going to convert it on 4.0. So, the question is how? On a C# solution is quite simple since there is the compile tab where you can change the target framework, but here on vb net i can't find it.
Here it is what i see on project properties[URL]..
I am attempting to write a program in Visual Basic Express 2010 that uses .NET Framework version 3.5 instead of 4. (The computers that I plan to use this program on only have .NET 3.5 SP1, and are painfully slow, so I don't want to upgrade them to .NET 4.)I have seen in the documentation that the Express edition does not have the option to change the target framework in the "New Project" dialog. However, when I go to the Project Properties window, there is not a drop-down list for the target framework, either.Can I change the target framework version in Visual Basic Express 2010?
View 2 RepliesI created a VB Console app and it defaulted to .NET 4 but I need it to be .NET 3.5. I've been looking but all the references I find say to change it on the 'Compile' tab in properties but I don't have a compile tab or anything else that lets me change the target framework.
Note: I'm using VS2010 Ultimate
I developed an app using the .net framework 3.5 sp1. I have now been told that the published version must not require sp1 but just the 3.5 framework.
So I uninstalled sp1 from my pc but not cannot publish the app. The app code will run without error but when I build it for publishing I get the error The "RequiresFramework35SP1Assembly" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:WINDOWSMicrosoft.NETFrameworkv3.5" directory.
I started a project in VB 2008 and the target Framework was obviously not 4, like it forces in VB 2010. The issue is the computers this application is being deployed to have 3.5 as the latest .NET Framework.
View 4 RepliesI've been working on a new application and realised that I want the target framework to be 3.5 (4.0 isn't rolled out yet). So, I changed it and now when I try and debug I get the following error:
"An error occurred creating the form. See Exception.InnerException for details. The error is: Unable to cast object of type 'System.Windows.Forms.SplitContainer' to type 'System.ComponentModel.ISupportInitialize'."
I really don't want to have to delete and recreate the splitContainer....
I have built a Dll and a Windows Service in vs2010. Both are targeting the .net 3.5 framework, but when I install it on the server it installs fine, but for some reason it targets the 2.0 framework and any time the methods fire that are using linq it crashes out with a clr20r3 error system.nullreferenceexception. Not really sure why it's not targeting .net 3.5.
View 10 RepliesI upgraded a solution with multiple projects from VS2008 to VS2010.One of the projects, a class library project, won't compile, although there are no errors in the error list.On the References tab of the project properties, the above error is displayed: "Could not resolve mscorlib for target framework '.NETFramework, Version-v4.0'.This can happen if the target framework is not installed or if the framework moniker is incorrectly formatted." .NET framework 4 v4.0.30319 is installed, and so is v3.5.All other projects build and work fine.Not all workstations experience this - some workstations can open the same solution without this problem occurring.Computers which have this problem also have VS2008 installed, and the same project compiles without issue in VS2008 on the same machine which has the problem in VS2010.
View 3 RepliesI 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 wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

It works just fine in Visual Studio 2010 and always manages to sync, but now that I'm trying to implement it on my client's computers, I always get the error:

View 2 RepliesI have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

View 4 RepliesI'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?

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)
View 2 RepliesI 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
