如何屏蔽Windows98的系统组合键(50分)

请教:如何屏蔽Windows98的系统组合键,以防止用户通过组合键切换到其它应用程序?

当你不需要让用户按Alt+Enter、Ctrl+Alt+Del、Ctrl+Esc等功能键的时候加入以下代码：<br>Var<br>temp:integer;<br>begin<br>SystemParametersInfo(Spi_screensaverrunning,1,@temp,0);<br>end;<br><br>当你要恢复功能键时用以下代码：<br>Var<br>Temp:integer;<br>begin<br>SystemParametersInfo(spi_screensaverrunning,0,@temp,0);<br>end;

SystemParametersInfo(SPI_SCREENSAVERRUNNING,1,0,0)

<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; procedure TForm1.FormCreate(Sender: TObject); <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; temp: Integer; <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; begin <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; SystemParametersInfo(SPI_SCREENSAVERRUNNING, 1, @temp, 0); <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end;
