Hi everyone,

I am trying to use SendMessage to send a WM_CHAR to a running instance
of Notepad.

So, in my simple VBA example, I am trying to send the character 'Q' to
the notepad and this should show this in the editor area, right?

So, I have the following API declarations:

WM_CHAR message
Public Const WM_CHAR = &H102

' Right control key
Public Const VK_RCONTROL = &HA3
' Q key
Public Const VK_Q = &H51

Private Declare Function EnumWindows Lib "user32" _
(ByVal lpEnumFunc As Long, _
   ByVal lParam As Long) As Long

Private Declare Function GetWindowText Lib "user32" _
   Alias "GetWindowTextA" _
(ByVal hwnd As Long, _
   ByVal lpString As String, _
   ByVal cch As Long) As Long

Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal _
hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any)
As Long

I also have functions that can do wildcard comparisons for the
FindWindow

So, in my code I have the following:

Dim appHWnd As Long
   appHWnd = FnFindWindowLike("*Note*")

   If (appHWnd) Then
       SendMessage appHWnd, WM_CHAR, VK_Q, ByVal 0&
   Else
       MsgBox "Could not find a running instance of "
   End If

I see that the windo handle is returned and the SendMessage call gets
executed, but I do not see a 'Q' in the notepad window.

Does the window have to have the focus for SendMessage to work or have
I misunderstood this whole process.

Please help.

Thx,
Anja
