Capture Cntrl-Alt-Del

[Guest_imported]

I need to capture Cntrl-Alt-Del as it occurs. I dont want to get it on notification of the window closing. Some of the other applications may shutdown before mine... Is there a way to hook the windows message queue to capture this? Am I making this too difficult ? Thanks

hi ahhchew,

Look up this command in the Delphi helpfile:

ShortCutToKey

I hope this helps,

BobbaFet Everyone has a right to my opinion.

Hi,
You can disable Ctrl+Alt+Del, Ctrl+Esc and Alt+Tab combinations by persuading Windows that a screen saver is running.
Use the SystemParametersInfo Win API function.
Example:
procedure DisableCtrlAltDelete(bDisabled: Boolean)
var
lpvParam: Boolean;
X: Long;
begin
X := SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, bDisabled, lpvParam, 0);
End;

I have not tried the above code in an application, so it could have errors, but this is just for an idea.

Oops! I didn't read your question fully, but hope the function helps.
I am not sure what the aim of your program is, but if you want it to keep running, why don't you register it as a service, but in this way, it won't appear on the task list!


var
bbb : Integer;

bbb := 0;
SystemParametersInfo( SPI_SCREENSAVERRUNNING, 1, @bbb, 0);
is correct way to disable Ctrl+Alt+Del. Welcome to the Pythian Games!
