Menu command

[WadeD]

Hi,

I've got the handle to a submenu that I wish to call. How can I use SendMessage to select it?

I'm using:
Call SendMessage(hSubMenu, &H100, 0, 0)

but I'm not getting a response.

Thanks in advance,
Wade

Hi WadeD,

Here's the code to select a Menu Item from a Window.

To use it, create a new project and place 2 command buttons on it.

In the VB Editor, paste the following:


Option Explicit

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function GetMenu Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetMenuItemID Lib "user32" (ByVal HMenu As Long, ByVal nPos As Long) As Long
Private Declare Function GetSubMenu Lib "user32" (ByVal HMenu As Long, ByVal nPos As Long) As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Private Hwindow As Long
Private HMenu As Long
Private HSubMenu As Long
Private MenuID As Long

Private Sub Command1_Click()
SelectMenuItem "Calculator", 2, 2
End Sub

Private Sub Command2_Click()
Unload Me
End
End Sub

Private Sub SelectMenuItem(WinName As String, Level1 As Long, Level2 As Long)
Hwindow = FindWindow(vbNullString, WinName)
HMenu = GetMenu(Hwindow)
HSubMenu = GetSubMenu(HMenu, Level1)
MenuID = GetMenuItemID(HSubMenu, Level2)
PostMessage Hwindow, &H111, MenuID, 0
End Sub


Be sure that you have "Calculator" open when you run it.

All the best.

This does work for calculator but not for the app that I'm calling. I know that I have the correct window and menu handles because I can get the menu text using these. Any ideas??

Thanks,
Wade

WadeD,

Using the code I posted, make sure that you are typing in the title of the window correctly (including the correct Case). Also, keep in mind that the Menu Items and Sub Items begin with 0 and not 1. Finally, a "--------" (line) in a drop-down menu should be counted when you trying to access the menu choices.

What's the name of the App that you are trying to access the Menu of anyway?

Hope this helps.

Chris
