to tell when shellexecute has opened

[Everytime]

I am using a shellexecute loop to open anumber of applications. Is it possible to find out when an application has opened before the loop repeats to open further apps?


Thx for any advise.

Try the FinnWIndow API

Dim handle as Long
handle =  FindWindow("classname","captiontext")
if handle <> 0 then
'window opened
end if

Almost forgot

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Or use EnumWindows.

Add to a Module.

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
Declare Function EnumWindows Lib "user32.dll" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long

Public Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As Long
    Dim Length As Long
    Dim sName As String
    Dim Temp As String
    Static iCount As Integer
    
    iCount = iCount + 1
    Length = GetWindowTextLength(hwnd) + 1
    
    If Length > 1 Then
      sName = Space(Length)
      GetWindowText hwnd, sName, Length
      Debug.Print Left(sName, Length - 1)
    End If
    
    EnumWindowsProc = 1
End Function

Usage

EnumWindows AddressOf EnumWindowsProc, 0

This will give you a list of all open windows. Then you can just find the window in the list.

That's great, thx Megatron & Vlatko.

Megatron,

The application paths that shellexecute will open are determined by the user at runtime. Hence I will not know what the window text will be.

So I thought of using the newly opened window's handle (hwnd). When Shellexecute opens the new window can I trap what whnd it is given?


Ta very much for any help,
