I'd like to know how to get a window handle (hWnd) in order to pass to Win32 API from VFP 5.0a.
The below C-code is what I've been read from one of the thread:
void GetObjectWHandle(ParamBlk *parm)
{
HWND hWnd;
MHANDLE mhWnd;
mhWnd=_WGetObjectWindow(&(parm->p[0].val));
hWnd=_WhToHwnd(mhWnd);
_RetInt((LONG)hWnd,8);
}
Then, what is the parameter type sould be specified in the FoxInfo ?
FoxInfo myFoxInfo[] = {
{"GETHWND",(FPFI) GetObjectWHandle, 1, "I"},
};
Once the .Fll have been created, what should I pass to it from a VFP form ?
In Visual FoxPro:
Set library to fll.fll
hWnd=GETHWND(Thisform) && doesn't work, type miss match
hWnd=GETHWND(_screen.activeform) && doesn't work. 'ACTIVEFORM' is not && an object
Thanks in advance.
