Passing variable to VB app

[sdpsc]

How do I pass a variable from a FoxPro app to a VB app? Thanks.

If the VB app accepts parameters, you could use ShellExecute():

DECLARE INTEGER ShellExecute IN shell32.dll ;
  INTEGER hndWin, ;
  STRING cAction, ;
  STRING cFileName, ;
  STRING cParams, ;  
  STRING cDir, ;
  INTEGER nShowWin

cFileName = "MyVBApp"
cParams   = "Parm1, Parm2"
cDir      = "C:\WhereverMyVBAppIs"
ShellExecute(0, "open", cFileName, cParams, cDir, 1)

It depends how you are executing the VB app. If you are using COM Automation, you pass them as normal VFP data types.

For instance, if the VB server expects a boolean, just pass a logical. And so on. VFP will handle the translation.

If the VB app is a normal DLL (not COM), then you will have to DECLARE it in VFP. You also have to worry about the different data types. If that is what you are doing, please supply some more information, and I (or someone) will be able to give you some guidance.
