See http://www.pobox.com/~skeet/csharp/f...ation.instance

(Phrased in C# terms, but easily understandable anyway.)

Thanks for the reply
itried what you gave me, but it comes back with
The filename, directory name, or volume label syntax is incorrect
Same error message with all the code below

Any ideas to what is wrong? I am doing something wrong with the string value

Thank

Heres what i tried: (VB Sorry :(

1
Dim firstInstance As Boolea
Dim mut As New Mutex(False, "Local\\C:\Program Files\CBSSE Apps\IT Utilities\F-Scan\bin\F-Scan.exe", firstInstance
2
Dim firstInstance As Boolea
Dim mut As New Mutex(False, "Local\\F-Scan.exe", firstInstance
3
Dim firstInstance As Boolea
Dim mut As New Mutex(False, "F-Scan.exe", firstInstance)

Yes. Firstly, you don't need the \\ - that's a C# escape sequence for
\. Secondly, you don't want to put the whole path to your app in the
string - just some unique name.

So, you might want:

"Local\CBSSE APPS - F-Scan"
Thanks

1]
Dim firstInstance As Boolean
Dim mut As New Mutex(False, "Local\\C:\Program Files\CBSSE Apps\IT
Utilities\F-Scan\bin\F-Scan.exe", firstInstance)
2]
Dim firstInstance As Boolean
Dim mut As New Mutex(False, "Local\\F-Scan.exe", firstInstance)
3]
Dim firstInstance As Boolean
Dim mut As New Mutex(False, "F-Scan.exe", firstInstance)

That last one should have worked, albeit not as a local mutex.
