Using GetPixel() -problems with output
Author
Hi. I'm using getpixel quite a bit and I'm having problems outputting text to the console window. For example:
I would guess that the cin.get( ) call causes an output buffer flush. Thus to get things working how you want you need to use std::endl like so:
std::cout << clr9 << std::endl;
std::cout << clr9 << std::endl;

Thanks. Do you know what Include I use or what I put at the top? I'm getting errors using MSVC++ 6.0 . It says:
error C2653: 'std' : is not a class or namespace name
error C2653: 'std' : is not a class or namespace name

Nevermind. Got it working thanks to you !!! Thanks man.
This turned out to be the winner for me:
cout <<clr17<<"\n"<< endl;
The endl at the end made it spit the output to the screen. Thanks. I think you gave me some MFC code but its all good thanks dude.
