How to simulate mouse click?

How can I simulate a mouse click in a program? I've been able to make the mouse move by itself, but now I'd like to know how to make it click on a button, for instance.

Thanks.

a button in ur own program?

say ur butten name is command1

so then just do this

private sub timer1.timer ()
command1_click
end sub

simple eh?

How can you simulate a click if its in another program?? I know its possible, and you have to use api, i think. somethin about WM_LBUTTONDOWN err somethin like that. I really need to know how to do this too, so anyone who knows please tell me!!

I recently tried something similar. I used the following
code and although the third party application button
appeared to be pressed, the click event was not being fired
off. Maybe the code will work for you though. :)

Code:

---

Private Declare Function FindWindowEx Lib "user32.dll" Alias "FindWindowExA" (ByVal hwndParent As Long, ByVal hwndChildAfter As Long, ByVal lpszClass As Any, ByVal lpszWindow As Any) As Long
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As Any, ByVal lpWindowName As Any) As Long
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Long, ByVal Msg As Long, wParam As Any, lParam As Any) As Long

Const WM_LBUTTONDOWN = &H201
Const WM_LBUTTONUP = &H202

Private Sub Command1_Click()
    Dim hwnd As Long
 
    hwnd = FindWindow(CLng(0), "WINDOW_CAPTION_GOES_HERE")
   
    'Has the window been found?
    If hwnd <> 0 Then
 
        Dim hWndCommandButton As Long
       
        hWndCommandButton = FindWindowEx(hwnd, 0, CLng(0), "BUTTON_CAPTION_GOES_HERE")

        'Has the Button control been found?
        If hWndCommandButton <> 0 Then               
            Call SendMessage(hWndCommandButton, WM_LBUTTONDOWN, 0, 0&)
            Call SendMessage(hWndCommandButton, WM_LBUTTONUP, 0, 0&)
        End If
    End If
End Sub

Good Luck.
