Click a button with code?

[josmond]

Does anyone know how to click a button using code. Probaly using the sendmessage command??

[benski]

If it's a vb button, simply call the event procedure for that button!

For example, to click the cmdExit button on the current form use cmdExit_Click

[josmond]

It's another button in another application

If you know the Window Handle (hWnd) for that button then you can use SendMessage API to do that:


Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const WM_KEYDOWN = &H100
Private Const WM_KEYUP = &H101
Private Const VK_SPACE = &H20


Public Sub ClickButton(hwnd As Long)
Call SendMessage(hwnd, WM_KEYDOWN, VK_SPACE, 0)
Call SendMessage(hwnd, WM_KEYUP, VK_SPACE, 0)
End Sub



Usage: ClickButton ButtonHwnd

I couldn't get Serge's code to work for a menu, though I'm using the correct menu handle (submenu actually).

Any ideas??
Thanks,
