i want to know how to hide the taskbar from a api function. please give me an example

MSDN]
Option Explicit

Dim handleW1 As Long

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

Private Declare Function SetWindowPos Lib "user32" _
(ByVal handleW1 As Long, _
ByVal handleW1InsertWhere As Long, ByVal w As Long, _
ByVal x As Long, ByVal y As Long, ByVal z As Long, _
ByVal wFlags As Long) As Long

Const TOGGLE_HIDEWINDOW = &H80
Const TOGGLE_UNHIDEWINDOW = &H40

Function HideTaskbar()
handleW1 = FindWindowA("Shell_traywnd", "")
Call SetWindowPos(handleW1, 0, 0, 0, _
0, 0, TOGGLE_HIDEWINDOW)
End Function

Function UnhideTaskbar()
Call SetWindowPos(handleW1, 0, 0, 0, _
0, 0, TOGGLE_UNHIDEWINDOW)
End Function


td.

Don't use the SetWindowPos API function, use the ShowWindow API function instead for better results.


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

Private Declare Function ShowWindow Lib "user32" _
(ByVal hwnd As Long, ByVal nCmdShow As Long) As _
Long

Private Const SW_HIDE = 0
Private Const SW_SHOW = 5


Private Sub Command1_Click()

'Hide
Dim shelltraywnd As Long
shelltraywnd = FindWindow("shell_traywnd", vbNullString)
ShowWindow shelltraywnd, SW_HIDE

End Sub


Private Sub Command2_Click()

'Show
Dim shelltraywnd As Long
shelltraywnd = FindWindow("shell_traywnd", vbNullString)
ShowWindow shelltraywnd, SW_SHOW

End Sub

Better results?? Both SetWindowPos and ShowWindow send the WM_SHOWWINDOW message, thus they're exactly the same, and neither is better than the other.

I see now. Perhaps I missed a few things to that code.
I thought the SetWindowPos API function only set windows on top or on bottom. I see it hides and unhides as well.

So couldn't you also use postmessage to post the wm_showwindow message and pass the hide or unhide argument? I'm just hypothesizing here; so don't get too technical about my argument names and all that. I'm just wondering about whether or not postmessage would work as well.

Depends on how quickly you need your message noticed. Postmessage isn't always quickly responded to.

I was just checking to see if it worked.
