ActiveX controls in VFP
Hi George
Hope You could give me a little advise on how to make the call.
The VB sample code declares an API call by the next code
Private Declare Function SendMessage Lib "User32" _
Alias "SendMessageA" _
(ByVal hWnd As Long, _
ByVal wMsg As Long, _
ByVal wParam As Long, _
lParam As Long) As Long
and calls the function with the next line of code
Call SendMessage(TreeView1.hWnd, _
TVM_SETBKCOLOR, _
0, _
ByVal RGB(255, 0, 0))
I’m not sure how to translate the Declare statement to VFP, since TreeView1 is the Treview Object dropped into the VB form.
A reference to the treeview object from a VFP method would be:
ThisForm.Olecontrol1.Object
According to VB documentation hWnd property is a handler.
¿What would be the handler from within VFP to ThisForm.Olecontrol1.Object and whih data type shall I use for the Declare statement?
Thanks in advance for any tips.
