How can the menu remain on the desktop after colsing the exe.

What are you doing in the exe ?

Could you try an alternative approach? For instance, hiding the form with the menu bar first, and doing a DoEvents to let Windows update the display, before actually ending the program.

Hi,

The MenuBar in my application is loading from third party. It having "refresh" function I have tried but not worth.

So I decided to go for Win API, by refreshing the desktop itself using WinAPI.

I have tried with "User32.dll" API with following peice of code.

Private Declare Function ShowWindow Lib "user32.dll" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function EnableWindow Lib "user32.dll" (ByVal hWnd As Long, ByVal fEnable As Long) As Long
 
Public Const SW_HIDE = 0
Public Const SW_SHOW = 5
 
Dim hWnd As Long
 
 hWnd = FindWindow("Progman", "Program Manager")
      ShowWindow hWnd, SW_SHOW
      EnableWindow hWnd, Visible
 

----> Still it's not working properly.
Please do help me.

Thanks,

Have you tried the much simpler method, of just covering up the whole desktop with a form, then removing it? In other words, maximize a form, DoEvents (to let Windows update the display) then simply close your application. If the whole desktop is hidden behind something else, that will force Windows to redraw it. Or in Windows terms, that will "invalidate" the whole desktop.

By the way, I don't know whether that API code will work or not. But it looks to me as though it's out of date. Program Manager hasn't been used since about Windsows 3.1, I think.
