Help With API

[FourBlades]

I found this http://msdn2.microsoft.com/en-us/library/aa458041.aspx
but I haven't got a clue about how to use it.
I've had very little experience in useing APIs with VB6, and I probably don't remember how to do those now anyway.
Can someone point me to a location that will show me how to use this API? I need to use the full screen API.

Thanks

A little search goes a long way.

Thanks jm. Actually I did search for quite a while and came up blank. Thanks for coming through again. You're a real help to many of us newbies.

Ok the following didn't work for me:

Const SHFS_SHOWTASKBAR As Integer = &H1
Const SHFS_HIDETASKBAR As Integer = &H2
Const SHFS_SHOWSIPBUTTON As Integer = &H4
Const SHFS_HIDESIPBUTTON As Integer = &H8
Const SHFS_SHOWSTARTICON As Integer = &H10
Const SHFS_HIDESTARTICON As Integer = &H20
 
<DllImport("aygshell.dll")>  _
Shared Function SHFullScreen(ByVal hwndRequester As IntPtr, _
  ByVal dwState As Integer) As Integer
End Function
 
<DllImport("coredll.dll")>  _
Public Shared Function GetCapture() As IntPtr
End Function
 
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
 
   Capture = True
   Dim hwnd As IntPtr = GetCapture()
   Capture = False
 
   SHFullScreen(hwnd, SHFS_HIDESTARTICON)
 
End Sub 'Form1_Load

The Error I got was:
"Can't find an entry point 'SHFullscreen' in a Pinvoke DLL 'aygshell.dll'."

Does that mean the name in the dll is different than "SHFullscreen"?

Any pointers to a full reference for API calls (beginners style) for Windows Mobile would be appreciated.

Try changing "aygshell.dll" to "aygshell.lib" and see if that makes a difference.

[FourBlades]

I did as you suggested. It returned "Can't find PInvoke DLL 'aygshell.lib'".

[jmcilhinney]

Hmmm... that one was a shot in the dark.

The doco you linked to says it requires Windows Mobile 2000 or later and Windows CE 3.0 or later. Are you using an older version of either?

Hi,
full screen shown at http://www.vbforums.com/showthread.php?t=452464

Are you using PocketPC - I don't think aygshell comes with CE - just PPC. Can you check it is on your device?

By default, a lot of the system DLLs are hidden. You can see them when
using the Remote File Viewer or when setting Explorer up to not hide
anything; otherwise, you don't see them.

Sorry, Been Busy.

The Version Is Windows Mobile 2003 v 4.21.1088
So it should have worked, correct?

Hi,
as I asked before, have you checked whether aygshell.dll is on your device?

The version doesn't matter if the dll is not on the device.
