Quite a lot, indeed. Roll eyes | :rolleyes:

What about a good C programming language book or tutorial?

Maybe he should turn to do some HTML or ASP, as what he says in his profile.

Whatever fancy language he uses, he definitely needs a good C tutorial (every man needs to feel the thrill of the real thing, sooner or later... Roll eyes | :rolleyes:

How to cacth application crash

Hi,

I'm working in MFC and have a problem with files that are used by my app. At opening time my app open some files and set's the readonly property to them. Everything works just fine if the app doesn't crash. If the app crashes the files remain readonly. My question is... in what wya can I catch some kind of messages or something when my app crashes and then reset tfe file attributes to previous state?

Thanks

You don't worry about your application crashes, do you?

My opinion is that you should rather be worried about *why* your application is crashing and how to prevent it, than worrying about the file attributes.

You can implement your own unhandled exception filter and attempt to reset file attributes from within the handler.

Read all of the articles from Hans Dietrich to get a grasp of the concept. http://www.codeproject.com/KB/debug/XCrashReportPt1.aspx[^]

What do you mean by "debug only one function" ?

You can set a breakpoint into this function and step line per line with the F10-Key

Keep the cursor in the line of code where you want the execution to stop and then press F9. This will set a breakpoint. Alternatively, you could use DebugBreak(); or use __asm int 3;

Example:

MyFunction(int iVal)
{
//do something

i = i+1; 
__asm int 3; // <<-- User break point will called here.

///
}

I think is quite clear what he means:
Debug (compile and run) only one function without having to build+run the whole app; may be passing it some arguments using some kind of dialog.
Im googling the same subject.
I think that a good solution would be to call that function just at the beginning of your app and use a breakpoint as they say.
