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.

///
}

Ever heard of a 'break point'?

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.

If you need to close the formerly open documents, then you have to terminate the process whose handle corrensponds to the one returned (if any) by hProcess member of SHELLEXECUTEINFO. But gracefully terminating such process isn't a simple task (at least IMHO).

And why don't you simply check if the file exist before opening it ?

What the hell are you talking about Confused | :confused:

?

How do you open your file ?
Where is this message coming form ? Do your program display it ?

You really need to explain your problem in a nore understandable way...

1. Copy paste the above code into your project.
2. Change the path of the file name.
3. Compile and run.
4. I pity your employer.
