hide the task bar and input panel in Windows Mobile

when
develop the WM apps sometimes we need to hide the task bar and input panel.

here
some methods are introduced with both C++ and C#.

C++:


by
the function SHFullScreen(), we may hide and show the taskbar, Input Panel
button, or Start menu icon.

and
it's easy to use.

//
hide

void
CHideInputDlg::OnBnClickedButton1()

{

BOOL bRet = false;

RECT rc;

DWORD dwState = (SHFS_HIDETASKBAR |
SHFS_HIDESTARTICON | SHFS_HIDESIPBUTTON);

bRet = SHFullScreen(m_hWnd, dwState);

// Next resize the main window to the size
of the screen.

SetRect(&rc, 0, 0,
GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN));

MoveWindow(rc.left, rc.top, rc.right-rc.left,
rc.bottom-rc.top, TRUE);

}

//
show

void
CHideInputDlg::OnBnClickedButton2()

{

BOOL bRet = false;

RECT rc;

DWORD dwState = (SHFS_SHOWTASKBAR |
SHFS_SHOWSTARTICON | SHFS_SHOWSIPBUTTON);

bRet = SHFullScreen(m_hWnd, dwState);

// Next resize the main window to the size
of the work area.

SystemParametersInfo(SPI_GETWORKAREA, 0,
&rc, FALSE);

MoveWindow(rc.left, rc.top,
rc.right-rc.left, rc.bottom-rc.top, TRUE);

}

and
there is another more classical way to hide or even disable the task bar: find
it's handle and do what ever we want. But the method doesn't work for input
panel.

//
hide

void
CHideInputDlg::OnBnClickedButton3()

{

HWND pWin = NULL;

pWin =
::FindWindowW(_T("HHTaskBar"), _T(""));

::ShowWindow(pWin, SW_HIDE);

//::EnableWindow(pWin, FALSE);

RECT rc;

SetRect(&rc, 0, 0,
GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN));

MoveWindow(rc.left, rc.top,
rc.right-rc.left, rc.bottom-rc.top, TRUE);

}

//
show

void
CHideInputDlg::OnBnClickedButton4()

{

HWND pWin = NULL;

pWin =
::FindWindowW(_T("HHTaskBar"), _T(""));

::ShowWindow(pWin, SW_SHOW);

RECT rc;

SystemParametersInfo(SPI_GETWORKAREA, 0,
&rc, FALSE);

MoveWindow(rc.left, rc.top,
rc.right-rc.left, rc.bottom-rc.top, TRUE);

}

by
the way notes that both the height of task bar and the input panel are 26.

C#


while
in the C# platform, the work is much easier,

just
change the property of the form:

FormBorderStyle: None;

WindowState: Maximized;

Size:
your
screen size;

by
the setting, the task bar is covered, put the input panel is still there, cause
the panel is associated with the component MainMenu, just delete the component,
we would get a clean screen.
