Hey guys. Unfortunately, I am C++ Newb. I have only been learning it for about 6 months or so.
Anyways back on the road, will I ever need to use a complete Main function deffinition in programs that have nice GUIs and everything?
Or is that only for programs that work only on the DOS window?Code:int main ( int argc, char *argv[] )
Even GUI programs can be started from the command line.
Even something simple like
notepad.exe myfile.txt
Note how, when you double-click a file in explorer in Windows, notepad opens that text file?
That's because the file is sent via the command line!
notepad.exe %1
So it's definitely there, even for GUIs.
So, as others have said, yes. However, Windows GUI applications do not start at "main", they start at "WinMain()", which has a different format for command line arguments.

Only if the programmer wishes to use 'WinMain' as the starting point; nothing provided by 'WinMain' is magic.

Sure, but it's customary to use WinMain rather than main. I agree that it's not compulsory.Quote:

Nonsense. There may be some suite that requires 'WinMain', but I doubt it.Quote:

I'll be happy to change that if someone shows how it's possible to do it w/o WinMain with GCC.
Last I tried, I just got linker errors (using C::B as IDE and GCC as compiler).
The IDE is the problem; with GCC at the console, it works by default.
