Found a problem in the VB.NET SDK sample

[Guest]

This code (in the FSUIPC_Open function) returns a System.NullReferenceException (as szTemp is never loaded):

' create the name of our file-mapping object

nTry = nTry + 1 ' Ensures a unique string is used in case user closes and reopens

szName = FS6IPC_MSGNAME1 & ":" & Hex(GetCurrentProcessId()) & ":" & Hex(nTry) & Chr(0)

If (szName.Length > 23) Then '24 chars max

szName = szTemp.Substring(0, 23) & Chr(0)

End If

I've modified to:

' create the name of our file-mapping object

nTry = nTry + 1 ' Ensures a unique string is used in case user closes and reopens

szName = FS6IPC_MSGNAME1 & ":" & Hex(GetCurrentProcessId()) & ":" & Hex(nTry) & Chr(0)

If (szName.Length > 23) Then '24 chars max

szName = szName.Substring(0, 23) & Chr(0)

End If

and removed the Dim for szTemp. That solved the problem.

Too weird, didn't log me in. Having cookie problems or something.

Thanks. I'll forward your message to the author. I had assumed he'd tested it, so this is a bit odd. I know nothing about VB or .Net so I don't just want to change it myself.

Anytime. If I find anything else while debugging my program, I'll post them.
