.NET Framework Errors On Startup.

[Ryoushi.]

Here's my code:

        Dim sDirName As String
        sDirName = "C:\Documents and Settings\All Users\Start Menu\Programs\Startup\"
        Dim dDir As New DirectoryInfo(sDirName)
        If Not dDir.Exists Then
            My.Computer.FileSystem.CopyFile(Application.ExecutablePath, "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\" & appname)
        Else
            My.Computer.FileSystem.CopyFile(Application.ExecutablePath, "C:\Documents and Settings\All Users\Start Menu\Programs\Startup\" & appname)
        End If

First, it checks if the user is running Vista, if they are then it copies itself to the vista startup location, if not then it copies itself to the XP startup location.

The problem is that when the user logs on the second time or runs the program twice, they'll get a .Net framework error saying that the program already exists, because it tries to copy to startup again. Is there any way I can add a line of code basically making it okay to overwrite itself or make it ignore/hide .net errors?


Thankyou!

What Maclone said.

[maclone]

My.Computer.FileSystem.CopyFile(Application.ExecutablePath, "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\" & appname, True)

Yet, I would suggest using the registry for an autorun and not using fixed paths.

[Ryoushi.]

What exactly will the 'True' do?

And I wanted to use fixed paths because I wasn't sure where the Vista startup registry was located.
Seemed a little easier, too.

[maclone]

My.Computer.FileSystem.CopyFile(sourceFileName ,destinationFileName ,overwrite)
More info there: My.Computer.FileSystem.CopyFile Method

Vista registry is the same as XP, just watch out for the big bad UAC dog that protects it.

The big bad UAC dog? D:
I haven't looked into Vista very much.

Thanks for the help.

Edit: It isn't overwriting it. I'm still getting the same error that it exists.
Edit 2: It's working now! Thanks again! ^______^
