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.
