Guest Posted June 1, 2003 Report Share Posted June 1, 2003 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. Jim Link to comment Share on other sites More sharing options...

Pete Dowson Posted June 1, 2003 Report Share Posted June 1, 2003 This code (in the FSUIPC_Open function) returns a System.NullReferenceException (as szTemp is never loaded): 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.

jyoungken Posted June 2, 2003 Report Share Posted June 2, 2003 Anytime. If I find anything else while debugging my program, I'll post them. Jim Link to comment Share on other sites More sharing options...
