Blocking system keys

Question

I'm develpoing with NetBens4.1 / Windows CE 3.0 / JeodeJVM 1.2.
I'd solved the Runtime.exec() lack in that JVM implementation by JNI calls to DLL's developed with Microsoft EVC++3.
Somebody have's an C++ example on how to block system keys like CTRL+ESC, ALT+TAB in Windows CE ?
Registry settings would help to...

Answer 1

Found out.
The taskbar get's the ALT+TAB and the CTRL+ESC events, so just disabling it locks these keys. Heres the JNI code:
SysLib.cpp
JNIEXPORT jint JNICALL Java_sys_SysLib_HideTaskBar
(JNIEnv *env, jclass obj) {
HWND hTaskBarWnd;
HWND hDeskTopWnd;
int rc=1;
// find the window and hide
hTaskBarWnd=FindWindow(_T("HHTaskBar"),NULL);
if (hTaskBarWnd)
EnableWindow(hTaskBarWnd,FALSE);
ShowWindow(hTaskBarWnd,SW_HIDE);
else
rc= -1;
// find the desktop window and resize it
hDeskTopWnd=FindWindow(_T("DesktopExplorerWindow"),NULL);
if (hDeskTopWnd)
SetWindowPos(hDeskTopWnd,NULL,0,0,GetSystemMetrics(SM_CXSCREEN),
GetSystemMetrics(SM_CYSCREEN), SWP_NOACTIVATE | SWP_NOZORDER |
SWP_NOMOVE);
else
rc= -2;
return rc;
JNIEXPORT jint JNICALL Java_sys_SysLib_ShowTaskBar
(JNIEnv *env, jclass obj) {
HWND hTaskBarWnd;
HWND hDeskTopWnd;
int rc=1;
// find the window and show it
hTaskBarWnd=FindWindow(_T("HHTaskBar"),NULL);
if (hTaskBarWnd)
EnableWindow(hTaskBarWnd,TRUE);
ShowWindow(hTaskBarWnd,SW_SHOW );
else
rc=-1;
// find the desktop window and resize it
hDeskTopWnd=FindWindow(_T("DesktopExplorerWindow"),NULL);
if (hDeskTopWnd)
SetWindowPos(hDeskTopWnd,NULL,0,0,GetSystemMetrics(SM_CXSCREEN),
GetSystemMetrics(SM_CYSCREEN)-26, SWP_NOACTIVATE | SWP_NOZORDER |
SWP_NOMOVE);
// Note: 26 is the taskbar height it should be computed.
else
rc=-2;
return rc;
}
