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 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 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 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've developed an application using VB 2008 Express and there are some customers using it,of course they have framework 3.5 installed.Can I upgrade to VB 2010 but keep target of my project to framework 3.5 (there is a option on Compile tab to chose target framework version),is it a good idea or not ?
View 5 RepliesProblem: 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 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'm programming in VB using Visual Studio 2005 Professional. I have a code munger perl script that generates some of the *.vb files that I want to compile. The script and the associated files are in my project directory, and when I run the script from the OS command prompt, it writes the files in the same directory, which is what I want. Rather than do this, I want to invoke the perl script as a pre-build event. I've gotten it to work ... almost. The only issue now is that the files are now deposited in TargetDir (/bin/Release e.g.) instead of ProjectDir. I could just change TargetDir to be ProjectDir, but that seems like I'm asking for trouble. Is there a way to separately specify the target directory for pre-build commands? Or change it to ProjectDir, then change it back after I'm done with the pre-build?
View 1 RepliesWhat actually happens when you target the .NET 3.5 framework in Visual Studio? What does that actually do? Does it somehow "flag" any of the output files and associate them with the framework version?
View 1 RepliesAll my application does is downloading files and doing string manipulation. I don't think I need .NET 4.0 for that. I changed the framework to 2.0, so more people can use my application without having to install a newer version.[code]...

I was changing the .NET framework from 4.0 to 3.5 (because of an incompatbility we discovered in a third party dll) and everything went fine except some .RESX file got messed up.

View 2 RepliesI have a tough situation that I don't really know how to code. I have one main list of point that contains all the points on a picture that are black.(1point=1pixel) I need to group all the black pixels that are less than 15(more or less) pixels away from each other into one Separate list. In the end I want about 5 lists.
What I said above is what I think is best to detect the centre of a shooting target. This information is just for those who think they know a better way. Each card has 5 targets on it and I need to detect the centre of each target. Ignore the sticker on the top target, in all cases the top one will look like the rest.
I have an desktop application that references several dlls. All are targeted for .Net 3.5, x86. The applicaiton has been deployed for several years and was upgraded from visual studion 2008 to 2010 last year. I have made several changes to the app since then (as recently as last Thursday) with out any issues. Now, everything builds, but when I run the application, I get a type initialiazer error when one of the projects is loaded by the main application.
The error messsage is {"Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.":"System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}.
There were no changes to this project since the last successfuly deployment last week, but today I am getting this error.

View 8 RepliesOk a simple question, I should know the answer but I am embarrased to ask. How do I get the .Net 4.0 framework deployed with my application when I publish it.Instead of having to download it on other pc's. Im sure its just a tick box in the preferences/settings somewhere.
View 3 RepliesI was messing with my program as I was having trouble getting it installed on machines without VB Express installed already. I adjusted the .Net requirement to 3.5 as I figured more people would meet that requirement without additional installs and now I get this error on my program when trying to change settings.Any idea how to get this set back up correctly.I'm on a Windows 7-64bit machine, using VB Basic 2010 Express.[code]
View 11 RepliesI'm creating an updater for an IP address, and I need to ensure that only one instance is running on the computer. This is to prevent (or at least make it more difficult for) having multiple tunnels running (it's an updater for an IPv6 tunnel).I've seen various ways of doing it in VB 6.0 and early .NET, but nothing that deals with .NET 3.5 or VIsual Basic 2010.

View 1 RepliesI have a question to ask you. All of the programs that I made always worked perfectly in my PC. But, whenever I test it on another PC, it requires a thing like... Microsoft .NET Framework Version 4. Which is really annoying, cuz that thing installs in 15 minutes. I mean, can I do something about this? Is this common?

View 7 RepliesI used to write code at a previous job in lots of languages, VB just one of them. At my new job I am tasked with writing code again. I have picked up VB 2010 express to get started and will move forward from there. The problem that I am facing is that 2010 uses the .net 4.0 framework. This is too new for the add-ins to support.
It follows, my question: Is there a way that VB .net 2010 can be forced to use a specific .net framework? Can I tell it to use the .net 2.0 for instance?
Anyone use the framework binarysearch methods?Can they do lower and upper bound searches?
