Wenn the programm is calling this function, it hangs on the

ph = openSocket(port, Peer$)

Port = 102 (as long)
Peer = 192.168.0.1 (as string)

i use

Microsoft studio 2008
Vista 64 Bits
write in visual basic

Microsoft Visual Studio Solution (.sln)
file included in the *.rar

Thank you.....

ph = 0

REM uncomment the daveSetDebug... line, save your sheet
REM run excel from dos box with: excel yoursheet >debugout.txt
REM send me the file debugout.txt if you have trouble.
REM call daveSetDebug(daveDebugAll)
initialize = -1
Peer$ = Form1.TextBox1.Text
port = 102
'Form1.Label3.Text = openSocket(port, Peer$)
ph = openSocket(port, Peer$) ' for ISO over TCP

If (ph > 0) Then
di = daveNewInterface(ph, ph, "IF1", 0, daveProtoISOTCP, daveSpeed187k)
res = daveInitAdapter(di)
If res = 0 Then
' with ISO over TCP, set correct values for rack and slot of the CPU
Rack = Form1.TextBox2.Text
Slot = Form1.TextBox3.Text
dc = daveNewConnection(di, MpiPpi, Rack, Slot)
res = daveConnectPLC(dc)
If res = 0 Then

EndIf
EndIf

EndFunction

Hallo Rick,
i think, this is the initialisation routine for LibNoDave with Excel, but i am not sure. I recommand the following routine, which is tested with VB2005:

Good Luck

IdOn`t know i think its Any CPU.
But i switched to Visual Basic Express.....
I know that on my Laptop 64 Bits they file project was not working.

that means wenn is call a Libnodave function it crasehes.

On my 32 Bit machine the projectworked oke.

When you compile an application as Any CPU, it will run on a 64 bit machine in 64 bit mode.
libnodave is a 32 bit dll, so you have to compile your application as x86.
It's not allowed to mix various assemblies/dlls in different machine modes.
