Yes. It is possible using some WinAPI (ShellAPI?) functions. If you are a programmer, I´ll look it up for you...

Disable Windows Shortcuts
Hello Mr. Hirsch.

I'am from Germany. I want to disable the Shortcuts Strg+Esc, Alt+F4, Strg+Alt+Entf. Leider ist mir das noch nicht gelungen. I'am an programmer.

If you could give me an advice,
and help me in this special point.
This would be very, very nice,
maybe we smoke a littel joint!

*Joke*

TNX!

What´s your programming language then?
for C:
- in your WndProc, use:
Code:
// disable alt-f4
if (msg.message==WM_CLOSE) return 0;


- anywhere use:
Code:
// claim your program is a password protected screen saver, this disables ctrl-alt-del, alt-tab and ctrl+esc
int old;
SystemParametersInfo(SPI_SCREENSAVERRUNNING,true,(void*)&old,0);

Be careful, this will lock your whole system, if your program breaks there is no way around pressing the reset button!

I guess yes. But honestly, I have no idea about VB...

Maybe have a look at msdn.microsoft.com . there is also the "official" docs for this function.

First of all, i am a student from the netherlands and i'm a beginner programmer! i've got the same problem like above.

I see you've got the solution but in my programm it will not work, c++ builder gives an error at:

Code:
if (msg.message==WM_CLOSE) return 0;


you also said that you have to use this part in the wndproc, but I think i haven't a wndproc?? is there an other manner?

The other part you gave, gives no errors, but i still can use Alt Tab, Alt F4 etc...

i don't understand that,

can you please help me?

Thanks in advantage!

R.

You do have a wndproc. You just can´t see it (yet)

It gives you an error because I assumed the reader has some basic knowledge about WinApi programming and can adapt the code to his variable naming and other needs. Sorry, you can hardly understand or use the code without this. Find out what a wndproc is and how windows uses messages, you´ll see then.

Ask that in the C/C++ forums, this is the wrong forum to discuss this anyway.

A hint: the WM_CLOSE part (disallow closing the window) can be done completely different in Borland C++. Have a look at the TForm::OnCloseQuery event.
