How To Hide Desktop Icons of Active Apps?

As the name suggests the Windows Operating System executes the application as different Windows.

User sees the Desktop as the Primary Window and all other visible applications are queued or tiled on Desktop. To take control of these applications, Windows programmers suggest to first find the Handle – a Unique Id that refer to a Application or Window.

Once you get a handle to all Windows, all other jobs are easy to process with Windows API. The Excel App in this app uses the following steps.

  1. FindWindowEx – Get list of all active Apps.
  2. IsWindowVisible – Check whether the Apps is visible or not.
  3. GetWindowText – Get the Windows Title.
  4. ShowWindowAsync – Use API to make the app hide.

Public Declare Function IsWindowVisible Lib "user32" (ByVal hwnd As Long) As Long
Public Declare Function ShowWindowAsync Lib "user32" (ByVal hwnd As Long, _
    ByVal nCmdShow As Long) As Long
Public Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" _
   (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Public Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" _
