[python-win32] Simulating a mouse click - lParam

[Rickey, Kyle W]

I tried using the InvalidateRect but it had not effect. Below is the
code I used.

TCM_SETCURSEL = 0x130C
win32gui.SendMessage(hwnd, TCM_SETCURSEL, 3, 0)
win32gui.InvalidateRect(hwnd, None, True)

I'm thinking I need to send the TCN_SELCHANGE message to the window, but
I don't know how to do that. From googling I find out I need to use
WM_NOTIFY and here's what I've got so far:

win32gui.SendMessage(hwnd, win32con.WM_NOTIFY, 

I'm having trouble finding the value for TCN_SELCHANGE as it's not
wrapped in win32con nor is it defined on the msdn website. How
frustrating...

I also don't understand how to construct the final parameter for
TCN_SELCHANGE. Thanks again for the help.

Assuming you have the top-most window of the app, you should be able to
use FindWindowEx to find the tab control by class name; you shouldn't
have to enumerate for it.  After you send TCM_SETCURSEL, you should be
able to call InvalidateRect to force the window to redraw.

Do you have the Windows SDK installed?  You can use the "spyxx" tool to
explore the window configuration of the app you're examining.
