FindWindowEx to get MDI Child handle?

Can anyone explain to me how to use the FindWindowEx function to get the handle of a mdi child?

I used

Code:

---

WinWnd = FindWindow(vbNullString, "My App Title")

---

to get the handle of the parent window. But when I try

Code:

---

    bWnd = FindWindowEx(WinWnd, ByVal 0&, vbNullString, "My Child Title")

---

bWnd is always 0...

"MyChildTitle 1" is the only child form under the parent. I've tried with two children but it still wont pick up any of them...any ideas?

Thanks.

FindWindowEx only finds parent windows.

After you have the handle to the parent MDI window then call EnumChildWindows

MDIhWnd is the handle of the parent

Code:

---

'in a form
Private Function GetChild(MDIhWnd as long) as long
    Dim MDIhnd as long
    Me.AutoRedraw = True
    EnumChildWindows MDIhWnd, AddressOf EnumChildProc, ByVal 0&
End Function

'in a module
Declare Function GetDesktopWindow Lib "user32" () As Long
Declare Function EnumChildWindows Lib "user32" (ByVal hWndParent As Long, ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long
Public Function EnumChildProc(ByVal hwnd As Long, ByVal lParam As Long) As Long
    Dim sSave As String
    'Get the windowtext length
    sSave = Space$(GetWindowTextLength(hwnd) + 1)
    'get the window text
    GetWindowText hwnd, sSave, Len(sSave)
    'remove the last Chr$(0)
    sSave = Left$(sSave, Len(sSave) - 1)
    If sSave <> "" Then Form1.Print sSave
    'continue enumeration
    EnumChildProc = 1
End Function

Thanks Jim, I had seen the EnumFunction in the API guide but I wasn't sure it was what I needed since the decription of FindWindowEx said it searched child windows.

Anyways, it worked, I got the handle, thanks a bunch =)
