Hiding SIP Icon Revisited

I have been using the FindWindow function to get the handle to the
ms_sipbutton and using SetWindowPos to hide it. This has worked well
in Windows Mobile 2003 SE, but with a new test PDA (Dell 51v) running
Windows Mobile v5.0, it no longer works. Has anyone had experience
with this yet and found a workaround. Thanks, Terry.
 
Across all versions of Pocket PC you should use SHFullScreen API with the
SHFS_HIDESIPBUTTON constant. The function isn't sticky though so you have to
call it whenever your form comes back into focus from another form or
MessageBox.

[DllImport("aygshell.dll", SetLastError=true)]
private static extern bool SHFullScreen(IntPtr hwnd, int state);

[Flags()]
public enum FullScreenFlags
{
ShowTaskbar = 0x1,
HideTaskbar = 0x2,
ShowSipButton = 0x4,
HideSipButton = 0x8,
ShowStartIcon = 0x10,
HideStartIcon = 0x20,
}

Thanks for the rapid reply. I had already tried this method in
WM2003SE and it didn't do anything. I tried it again in WM5 and it
still doesn't do anything. That's why I used the alternate method.
Thanks for your help. Terry.
 
Hi, I'm surprised it didn't work as I've used it in both PPC2003 and v5.0
code. I'd check that the hwnd you are passing in is valid, I used the
Capture / GetCapture method to get it for the form.

I'm using the same code and it's definitely returning a valid handle.


Friend Function GetHwnd(ByVal Form As Form) As IntPtr
Form.Capture = True
Dim hWnd As IntPtr = GetCapture()
Form.Capture = False
Return hWnd
End Function

Friend Sub ShowSIP(ByVal pFormHwnd As IntPtr, ByVal pVisible As
Boolean)
SHFullScreen(pFormHwnd, IIf(pVisible,
FullScreenFlags.ShowSipButton, FullScreenFlags.HideSipButton))
End Sub

' From my form:

ShowSIP(GetHwnd(Me), False)

BTW, is there any way to disable the irritating security prompt
(unknown publisher) every time I launch my project?

Thanks, Terry.
