    Question Pixel...

    How would I go about making a pixel to come up on the screen and change its color and size?

    Like to make sprites or Galaga type ships?

    I cant seem to use Graphics.h in windows for some reason so I need to know what procedures or downloads i need to make to accomplish my goal.
    What is C++?

    So, you're using Win32 API? You can't change the size of a pixel, it is always a pixel. If you want to output one use the function SetPixelV( HDC, INT, INT, COLORREF );

    something like this
    SetPixelV( hdc, x, y, RGB( 255, 255, 255 ) );

    The RGB is a macro you can use to determine color of a pixel. 0 - 255 for each. If you want sprites, just make them in paint as a BMP and load the image to a HBITMAP and blt it to the screen. I don't know how much you know so, just ask more questions.

    console doesnt do graphics

    You can't make a console program with graphics. You will either have to make a DOS program or a Windows program. You should check out Allegro or find out about mode13h.

    As far as I know you can't use MODE 13h in win32 console mode application.
    Current projects:
    1) User Interface Development Kit (C++)
    2) HTML SDK (C++)
    3) Classes (C++)
    4) INI Editor (Delphi)

    you are using borland right?

    if u arent u cant compile that

    anyway your compiler knows about it so u must be using borland

    what u must do is to open a new project.

    in the project path and name, make it so u save your file in your

    bgi folder and the platform must be DOS not windows click on the

    library

    BGI and then click ok

    i'm using borland 5.0

    Whats wrong...

    Code:
    #include <iostream.h>
    #include <graphics.h>
    
    int GraphDriver;
    int GraphMode;
    
    int main()
    {
    	initgraph ( &GraphDriver, &GraphMode, "" );
    
       circle ( 5, 5, 10 );
    
       cin.get();
       return 0;
    }
