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?

View 6 RepliesI'm working on a program that set up as master/details. I'm working on making save checks in the program, so that if something gets changed, it gives a warning when leaving the form if it hasn't been saved. I've got it mostly working, but I'm having problems with when i get to my details section.
The details section is a DataGridView (DGV) that loads with a one to many relationship. I've got is set up right now that when the form loads, it takes and makes an array call aryOriginals, and as you close the form, it makes another array called aryClosing. It compares these two sets of arrays, and if nothing is different since the page opened, it will close without any problems. If it has been changed, a msgbox pops up to let the user know that there has been a change since they last saved and asks if they want to wait to close the form so they can save.
All of that is working great. What I'm having a problem with is doing the same thing with the datagridview. And before anyone suggests it, I can't use DataSet1.HasChanges, because that was giving me weird problems of saying there were changes when nothing changed due to a custom made combobox i use in a few of my datagridviews. So I need some way of comparing the two datagridviews. I've looked online, but can't seem to find anything with what I'm looking for.

I am using VB.NET 2008 Express Edition and INNO Setup. When I create a setup and run it, the resulting install is an older version of my project from, I think, 2 or 3 days ago. If I go back to my project in the developer window and run the project, it is clearly a newer version than the install. Since this installed version that comes up was done I have added a form and made many other changes.Is it because the build didn't exeucte? When you run the project doesn't it execute a build every time?I tried this again from a backup. (The backup is much more recent than the version I'm getting.) And it still does the same thing.Why does the install not match the project? It is not possible to go into the project and add the changes because they are already there.

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 am writing my first application in VB 2008 Express with .NET Framework versions 2.0, 3.0 and 3.5 installed. When completed, I assume the application will need to check whether it is running under .NET Framework version 3.5 or later. I have not found any properties that I could get which would give me this information about the environment in which the application is running. Is this something that the non-user code in which my application is wrapped by the IDE checks, or is it something that I have to check myself within the application ? If the latter, how would I do that ?

View 8 RepliesI need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I'm writing a code that will check if .net framework 3.5 SP1 is installed before installing the program.The command I found googling around was System.Runtime.InteropServices.Runtime Environment.GetSystemVersion..I wasn't able to verify the correct .net framework version using this command.I'm currently running 3.5 SP1 and this command is showing v2.0.Is there another way to get the correct .net framework version?
View 2 RepliesIs it possible to reduce the version of .net framework of my application. For example: Host using my application have .NET 2.0 I make changes in my app so that it always run as .NET 2.0 not the latest .NET 3.5
Or another idea i have is to deploy .NET 3.5 in installation package i.e. if he runs my app and it detects .NET version and if its not .NET 3.5 then .NET 3.5 installer should open else my app should run.
Mainly I ask this because I don't want to distribute both versions, and if I need to instal a 64bit .NET on an x64 PC and a 32bit .NET on a 32 bit PC then I would need to make this check in my loader application to download the correct version for the correct PC.

View 2 Repliesconfirm the forum for this question about Visual Web Developer 2010 Express. I found a VWD Express forum, but it was in Spanish... Lo Siento. My issue is selecting a down-level, 3.5, framework version as I create a new project/website. I have figured out how to CHANGE the target framework version once the website/project is created. I have the 3.5x installed on the system and available. The articles I have seen discussing this issue, refer to a framework version selection drop list in the new project creation dialog/wizard. I do not have that option.

I have a VS2010 solution (upgraded) that has two projects, an EXE and a DLL. In both the Target framework versions are 4.0. When one look at the references of the EXE project, one can see that the System.dll (and System.Core.dll and so for) references to the v4 version (the latest); however, in the DLL project the references points to the .Net Framework v2 version. Why is this happening? How can I make all my projects to point to the v4 libraries?

Is it possible to load a referenced assembly only if the .NET Framework version is lesser than a specific number? I'm using a selfmade LINQ library on .NET 2.0, but if the framework is 3.5+, it should use the M$ LINQ library, and ignore the selfmade one.
