怎样锁住屏幕和解锁?(在线给分)!!

[snowchicken]

我用EnableWindow(GetDesktopWindow(),FALSE);没反应

[LegerWu]

建立一个全局键盘和鼠标钩子,钩住所有键盘和鼠标按键,直到你按下解锁的按键,删除钩子.

void Lock(BOOL bFALG)
{
if (bFALG)
{
SystemParametersInfo(SPI_SCREENSAVERRUNNING, 1, NULL,0);
EnableWindow(GetDesktopWindow(),FALSE);
}
else
{
SystemParametersInfo(SPI_SCREENSAVERRUNNING, 0, NULL,0);
EnableWindow(GetDesktopWindow(),TRUE);
}
}

好像没什么用，我用的win2k.再想一想!

try to call functions exported by msgina.dll, maybe WlxDisplayLockedNotice can do it.

[wingsofwind]

LockWindowUpdate(GetDesktopWindow());
塞NULL进去就会解锁。

[wingsofwind]

LockWindowUpdate
The LockWindowUpdate function disables or enables drawing in the specified window. Only one window can be locked at a time.

BOOL LockWindowUpdate(
HWND hWndLock // handle to window
);
from MSDN

基本上锁屏比较困难,尢其在2000下,98下简单,用SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,1,NULL,0);就行了,2000下要用低级键盘钩子锁住
ALT+ESC,ALT+TAB等,而ctl+alt+del要用gina锁定,具体你可以搜索"锁定屏幕",以前有人问过,不过没有回答的很全面,我就是从很多问题中得到了解决方法的,整个过程还是比较复杂的.
