[Jhd.Honza]

Hello everybody!

I would like to click a button or menu from my application (like a BuzOf). I have only handle (by FindWindowEx). How to do it?

You can use the SendMessag API but I can't tell you how unless I know exactly what you're trying to do.

If you post more Details I'll see if I can Help.

OK. I would like to monitore the window and press any button in it, when it shows.

For example:

I will be looking by FindWindow to 'Security warning' window (showed by IE when recieving a cookie). When I found it, I would like to press a 'More Details' button (by my application, of course).
Who is friendly with BuzOf (www.basta.com) knows what I want.

Or:

I would like to change a 'Show images' option in IE accesing the registry. Then, if an instance of IE is running, press the View/Refresh menu. Please do not help me with such things like SendKeys "{F5}". I need to run any of menu items in various applications.

If it is clear, now, please help me...

Well, assuming you have got the windowhandle (lets call it hWind), you can send the WM_LBUTTONDOWN message followed by a WM_LBUTTONUP message

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Any) As Long
Private Const WM_LBUTTONDOWN = &H201
Private Const WM_LBUTTONUP = &H202

Private Sub Command1_Click()
Dim retVal as long
    retVal = SendMessage(hWind, WM_LBUTTONDOWN, 0&, &H10001) ' we click at an offset of 1 pixel by 1
    retVal = SendMessage(hWind, WM_LBUTTONUP, 0&, &H10001)
End Sub

This works well, but only if the window is enabled. I need to call its click subroutine, even it is disabled.

?

Can this be used to select a menu that's in another app? I need to select the Edit menu from another app. I have the correct handle but GetLastError returns 1400 (Invalid Window Handle). Is that because it's a menu?

Thanks,
Wade

To enable item do this (change "TITLE" to app's title):

w = FindWindow(vbNullString, "TITLE")
m = GetMenu(w)
sm = GetSubMenu(m,2) 'Change 2 to &Edit's index
'first submenu is 0
'first submenu can be an icon in MDI app(!)
EnableMenuItem sm, its index, &H400 or &H0

You type select; would you like to click the whole Edit menu or run a specified item? To run item, use SendMessage.

To my problem:
Is done
1. the do..loop method helped
2. as well (maybe not so) as SendMesage

I'd like to select the whole Edit menu. I can use SendMessage to select it, but I need to dropdown the menu instead. That's when it enables/disables its submenus.

Thanks,
Wade
