::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE ); using VS2005?

In my eVC++4 project I made my app fullscreen by doing the following:

SHFullScreen( m_hWnd, SHFS_HIDESTARTICON|
                         SHFS_HIDETASKBAR|
                        SHFS_HIDESIPBUTTON );

MoveWindow(15,70,220,180,TRUE);

::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE );

I have now converted it to VS2005 and m_pWndEmptyCB is no longer supported.

How exactly can I do the same as ::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE ); using VS2005?

Thanks

I am not certain if this will be helpful however according to http://msdn.microsoft.com/en-us/library/ew94tebd.aspx m_pWndEmptyCB is no longer supported because you now control the creation of the command bar so somewhere in your code you would have a call to CommandBar_Create http://msdn.microsoft.com/en-us/library/ms908131.aspx which will return the handle to your command bar when called (if successful), you could store this handle in a member variable, e.g.:

// Declare handle to control bar as object member variable
HWND hCmdBar;

// Initialize when creating the command bar
hCmdBar = ::CommandBar_Create(...

and later on pass it as the first argument to the CommandBar_Show method, e.g.:

::CommandBar_Show(hCmdBar, FALSE );

Do you use MFC in your project?
I think Lordof Ports is right. IN my application I just don't create the command bar, but the main window has WS_POPUP style, so it can cover the whole screen. I don't use the MFC.

One more thing - I control the WM_ACTIVATE to hide the system controls.
for example, this code will find the task bar:
HWND hWnd = ::FindWindow(TEXT("HHTaskBar"), NULL);
then: ShowWindow(hWnd, SW_HIDE);

or SIP button:
HWND HWnd = ::FindWindow(TEXT("MS_SIPBUTTON"), NULL);

Yes I use MFC in my project.

I also control the WM_ACTIVATE and I 'had' the following:
void CAbout::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized)
{
          CDialog::OnActivate(nState, pWndOther, bMinimized);  
          SHFullScreen( m_hWnd, SHFS_HIDESTARTICON|SHFS_HIDETASKBAR|SHFS_HIDESIPBUTTON );
          MoveWindow(0,0,240,320,TRUE);
          ::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE );      
}

I will try out your suggestions above to replace the m_pWndEmptyCB.
Thanks

The following does not hide the bottom SIP:

HWND HWnd = ::FindWindow(TEXT("MS_SIPBUTTON"), NULL);
::ShowWindow(HWnd, SW_HIDE);

Any ideas??

Thanks

Check if HWnd is NULL perhaps. According the FindWindow's description http://msdn.microsoft.com/en-us/library/ms633499.aspx it does not search for child windows, use FindWindowEx http://msdn.microsoft.com/en-us/library/ms633500(VS.85).aspx to search for child windows.

The post at http://forum.soft32.com/pda/Removing-SIP-icon-Command-Bar-ftopict58785.html might also be helpful although in that solution the button is moved.

HWND HWnd = ::FindWindow(TEXT("MS_SIPBUTTON"), NULL);
::ShowWindow(HWnd, SW_HIDE);
You can say millions times "it does not work" and it will not help. Please look for a mistake. Maybe there is something specific about your device or about OS image on it and so it does not work. I've not seen when it didn't work on a PDA since Pocket PC 2003 and it still work on WM 6.1.
Why you put the activate handler into About only? Is this the main window in your app? It should be in the main window - frame, dialog. Also pay attention that you are in this code when your app is becoming inactive.

Probably I understood what happens - after these games with the commandbar you need to redraw your window also - call invalidate for the main app window
