Making a program uncloseable

HOW would someone close it? You should be able to change the default frame so that it no longer has the cancel button.

 

Although one might make the GUI inaccessible, one could still terminate the process (kill on linux, or task manager on Windows), if you have sufficient permission to use those tools.

One could try to run the process with higher level permissions... and maybe another program which periodically checks to see if the desired process is still running... restarting it if weren't.

Can you be more specific about what you want to run?
and who you want to prevent from stopping it?

 

Your objective is a very bad idea.

 

If you wrote the program or have the source code you can do it for most user activity.

The syntax varies by programming language.
The generalized solution:
Setup a callback function on the close button.
Issue a cancel message when the function gets control.

 

I'll agree, but some places do this.

 

I guess my opinion is that anyone capable of writing an operational hook isn't going to need to ask. It is simply a non trivial task to write one that doesn't blue screen you.

The idea has legitimate uses, say like a sales app on dedicated terminal or even the "Did you really want to quit without saving" message. In the former case you probably want to disallow the standard base window decorations like min, max and the close buttons.

Callbacks are offered by the instantiation of a GUI control (the hook is hidden in the class).

Hooks usually imply a direct connection into the O/S message queue (not unique to Windows) and often have callbacks.

 

I always ask myself the same problem. If you get something on this, please submit it (the link or some other source)! Thank you!

 

Writing control systems for nuclear missiles, eh? :uhh:

 

Look can you be a more clear!
I wrote i program in C. Am i gonne introduce that code?
Another question is what does mean "PITA"?

 

Pain in the a...

 

Pita, n.
1. "An often round, brown, wheat flatbread made with yeast."
2. People Ingesting Tasty Animals?
3. See zeitghost, above.

 

Changing a active directory setting in a windows domain will do this. The user profile is tied to one program which is ran when the user logs in. When the program is closed, the user is logged out. This is very common in some businesses.

For example a denist that uses a vertical app for his whole business.
