Is there a way to check if two processes are the same program? One way I thought of is to compare GUIDs, but I dont know how to do that. Is comparing GUIDs good, or is there an easier way to compare processes?

Note:
the processes can have different file names, and may have different code (for different versions of the program)

So, one example is; you want to check if a process of Visual Studio 2008 is the same as Visual Studio 2010?

I have a program that can be updated. I want to check if this program is the same as another running program (to see if the program is running, aven if the other program is another version).

Fine the program application path and generate a CRC of the executable and check it again previous version CRC, long, sloppy but I dont know how to actually accomplish what your doing.

DreadNought, the files content will not be the same after he upgraded the program.

DreadNought, the files content will not be the same after he upgraded the program.

What do you mean that it will not be the same? You can put it into an equation like this:

Code: Select all

If crccodeversion1.0 = myprogram then 'nothing 
else update()

In which update() is the function to start the updater etc.

It might be possible to get some details from the assembly information.
You could check with FileVersionInfo.

Code: Select all

        Dim fvi As FileVersionInfo = FileVersionInfo.GetVersionInfo("C:\test.exe")
        If fvi.ProductName = "test" Then

        End If
