Source code to send clicks (Minimized)

Well let an example of some functions in VB6 to send clicks and pfs to the screen.
They work with the client miniminized or in background.

It is a way that I have not seen used in the examples in the forum but I think it is the most effective.

Unfortunately not comment on the code but the idea is this:

Send messages BUTTONDOWN / BUTTONUP directly to the window handle control that contains the display or which contains buttons pf. not to the window pricipal Co

GetHandleControl search recursively controlid in the windows daughters hwnd parameter and returns the handle of it.

You can find the controlid with WinSpy or similar and/or traveling checks at the function GetHandleControl modified to get extra info on the controls.

This work for spanish client. I suppose the identifiers of objects will be the same in different clients languages....

sry for my bad (or null) English :D
