well this is exiting, apparently my pipe server side of DBIM got completely messed up after I ran a cleanup on SVN.
Ammeh, here is basically a working version that should tell you everything you may need:
Begin Server.PipeRPC pipeCalculate
Left = 2280
Top = 1080
_ExtentX = 847
_ExtentY = 847
PipeName = "Calc Server Pipe"
Private Sub Form_Load()
Private Sub Form_Unload(Cancel As Integer)
Private Sub pipeCalculate_Called(ByVal Pipe As Long, Request() As Byte, Response() As Byte)
Text1 = Text1 & CStr(Request) & vbCrLf
Response = "0"
Funny, as soon as I created a fresh copy from the SVN my problem magically disappeared.
