Show and Hide windows Task Bar from Windows Application

[Jon_Boy]

So basically, would you and make the form size = screen.workingarea? This will work:

    With Me
        .TopMost = True
        .FormBorderStyle = System.Windows.Forms.FormBorderStyle.None
        .WindowState = FormWindowState.Maximized
    End With

You cannot, and should not, disable the TaskBar.

The only way to hide the Task Bar is to kill the Explorer process, but that's not acceptable to the user either.

simple test on google gives me over 100000 hits.

Public Const SWP_HIDEWINDOW As Integer = &H80
Public Const SWP_SHOWWINDOW As Integer = &H40
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Integer

Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Integer, ByVal hWndInsertAfter As Integer, ByVal x As Integer, ByVal y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal wFlags As Integer) As Integer

Private Sub bHide_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bHide.Click
Dim hSystray As Integer = FindWindow("Shell_traywnd", "")
SetWindowPos(hSystray, 0, 0, 0, 0, 0, SWP_HIDEWINDOW)
End Sub
Private Sub bShow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bShow.Click
Dim hSystray As Integer = FindWindow("Shell_traywnd", "")
SetWindowPos(hSystray, 0, 0, 0, 0, 0, SWP_SHOWWINDOW)
End Sub

That doesn't disable the TaskBar, it just hides the window temporarily. It's still not a good idea to do.

I guess I don't truly understand the purpose of the request. 1. If pdnet has the app in Kiosk mode, why are you worrying about the taskbar - you can't see it anyways? 2. Don't know about you, but I'd be pissed if I ran an app and it started changing my theme/settings in Windows without me allowing it to do so. All around bad idea to it.

Sometimes project specifications is to run it full screen so that the taskbar isnt visible. From what I gathered in his post, he doesn't want to disable it, just wants the same functionality as 'Autohide the taskbar' option. I'm kind of curious as to this myself.

The code I posted earlier in this thread accomplishes that. The form covers the task bar, just like VS if you run it in full screen mode without changing the settings or killing the task bar itself.
