Hi Philip,
>Does anyone know if VFP 5.0 support the Win32API COPYDATASTRUCT structure? I need to pass a message using WM_COPYDATA, and pass a pointer to Delphi 3.0 to this structure from within VFP.
Sure it does. All you need is a little public domain class that has been developed by Mark Wilden and myself and is currently in beta. You can get a copy if you want. The code would look like this:
ox = Create("COPYDATASTRUCT")
ox.lpData = "Some data!"
ox.cbData = Len(ox.lpData)
SendMessage(hwnd1,WM_COPYDATA,hwnd2,ox.GetPointer())
Define Class COPYDATASTRUCT as Struct
dwData = 0
cbData = 0
lpData = ""
cmembers = "l:dwData,l:cbData,pz:lpData"
Enddefine
