Mouse click sequel: Rodent's Revenge

There were like 2 or 3 or a billion posts with the same question: How do you simulate a mouse click?
The answer was the same: Find the control's hWnd, and SendMessage with wMsg as WM_CLICK or 2 SendMessage's with wMsg as WM_LBUTTONDOWN then WM_LBUTTONUP.

New question arose: How do you simulate a mouse click, but not clicking the hWnd, but clicking an area of the screen (Click X, Y)?

You may not like this because it includes another hWnd. Use the hWnd of the screen (desktop). I think it's zero, but I'm not sure.

Zero is the hWnd of NOTHING. To get the screen hWnd you have to use the API GetDesktopWindow. Well, what do I DO with the screen's hWnd?

In C/C++, you'd use
HWND GetDesktopWindow(VOID)
to return the handle for the desktop. I haven't found it in VB, but this might help you. Maybe you can find an API for it. I've noticed that you use the API's alot.

No, I didn't ask how to get the screen's hWnd. I know how. I've done it a billion times.
My question was what do I do with the hWnd? To simulate a mouse click I mean?
Should I use an AOL such as SendMessageByPoint(hWnd (= GetDesktopWindow) As Long, wMsg (= WM_CLICK) As Long, lParam (= 0&) As Long, wParam As POINTAPI) ?!?!?
Well, it's worth a try!

You sure were rude when I was just trying to help you out. Now you're giving similar advice:

GetDC allocates a Device-Context for the hWnd specified. This hWnd can be either:
0 (Zero) - Currently active desktop.
128 - First desktop (the one created when Windows started).
Any other number - A valid window handle.

Try this:

Code:

---

Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)
Private Declare Function SetCursorPos Lib "user32" (ByVal X As Long, ByVal Y As Long) As Long
Private Const MOUSEEVENTF_LEFTDOWN = &H2
Private Const MOUSEEVENTF_LEFTUP = &H4
Private Type POINTAPI
    X As Long
    Y As Long
End Type

Public Sub ClickMouse(X As Long, Y As Long)
    SetCursorPos X, Y
    mouse_event MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0
    mouse_event MOUSEEVENTF_LEFTUP, 0, 0, 0, 0
End Sub

Passing your coordinates will click the left button on the mouse.

Example: ClickMouse 500, 500

Ask Aaron Young. He's been able to help me
with basically every VB question.

This post is old and I posted it back when I was (so to speak) an idiot... Sorry!
