These are Pocket PC (aygshell to be specific) APIs. They shouldn't work on
a vanilla CE device.

Thanks Chris !!

Maybe you or somebody else can help me out how to get this working on the
CE.NET embedded device ? (not showing the win taskbar, because the user is
only allowed to use one program)

Any ideas are welcome !

Peter

Search the archives of this group for HHTaskBar

 

[Peter]

Thanks again Chris,

What I found didn't work on the emulator ?
I'm a newbie in so please bear with me.......

the hWnd returns 735584 so I guess the taskbar is found,
but I don't understand what the IntPtr.Zero does.

Must I do something extra ?

Peter.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Dim hWnd As IntPtr = FindWindow("HHTaskbar", Nothing)

hWnd = IntPtr.Zero

End Sub

<DllImport("coredll")> _

Public Shared Function FindWindow(ByVal lpClass As String, ByVal lpTitle As
String) As IntPtr

End Function
