[RESOLVED] TaskVisible = False [HELP]

[*PsyKE1*]

How I can do from my Form code to not appear in the TaskBar?

Form1.ShowInTaskbar = False

This runtime does not work ...
SetWindowLong ()?

Thanks

Set the ShowInTaskbar property to False. You can only do this in design time as far as I know.

If you want to do it during run time, then you can use this.

Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
 
Private Const SW_SHOW = 5
Private Const SW_HIDE = 0
Private Const GWL_EXSTYLE = (-20)
Private Const WS_EX_APPWINDOW = &H40000
 
Public Sub ShownInTaskBar(ByVal hwnd As Long, Optional bShow As Boolean = True)
    Dim lExStyles As Long
  
    lExStyles = GetWindowLong(hwnd, GWL_EXSTYLE)
  
    If bShow Xor (lExStyles And WS_EX_APPWINDOW) = 0 Then Exit Sub
 
    ShowWindow hwnd, SW_HIDE
    SetWindowLong hwnd, GWL_EXSTYLE, lExStyles Xor WS_EX_APPWINDOW
    ShowWindow hwnd, SW_SHOW
End Sub
 
Private Sub Command1_Click()
    ShownInTaskBar Me.hwnd, False
End Sub

As Chris001 said, the ShowInTaskbar property can only be set at design time, in the Properties window for the form. In code the property is read only, you can't set it through code like that.
