My window will not clear itself (vc++)

Okay....here's an interesting problem. I am using Visual C++ (6.0). Well....I am trying to get my window to clear ( in a console app. ). Well, at school (that uses Borland C++ 5.01) I've always used clrscr() from the conio.h file. But....when I include the header file and try and use the funtion....it doesn't work, and gives me one or more (typically more) errors. What's wrong and what should I be doing that I'm not?

Try including conio.c

Your conio at home might be not be including the actual implementation of conio.

What are your errors?

If that still doesn't work, try:

system("cls");
and you'll need stdlib.h

Hope this helps.

Conio.h is screen-based, whereas Visual C++ is window-based. But I guess when you excute a new program, it starts automatically in a cleared window.

This question is pretty often.

For years I've been using Borland C++ and can not imagine how hard is life without clrscr(), gotoxy(), textcolor() etc.

I can't believe Microsoft can not make it. Is there some license issue or something ?

That's why I prefer to work with Java. Its also platform-independent. But VC must be having some equivalent method I'm unaware of.

It is rather silly to try to do GUI stuff in a console app (which is why Microsoft does not bother to supply a high-level library of fns like cls and the beloved Borland gotoxy -- what is this, 1985?).  But there is a complete set of primitives one can use to manipulate the console.  For instance, here is a cls() fn and an example of usage.

#include <windows.h>
#include <stdio.h>   // for printf

void cls()
{
     HANDLE hConScreen=  GetStdHandle( STD_OUTPUT_HANDLE );

     CONSOLE_SCREEN_BUFFER_INFO rCBI;
     GetConsoleScreenBufferInfo(hConScreen, &rCBI );
     int nScreenBytesTotal= rCBI.dwSize.X * rCBI.dwSize.Y;

     WORD ClrWhiteOnBlack= FOREGROUND_RED | FOREGROUND_BLUE | FOREGROUND_GREEN;

     COORD pt; pt.X=0; pt.Y=0;
     DWORD nActual;
     FillConsoleOutputCharacter( hConScreen, ' ', nScreenBytesTotal, pt, &nActual );
     FillConsoleOutputAttribute( hConScreen, ClrWhiteOnBlack , nScreenBytesTotal, pt, &nActual );
}

void main()
{
     printf("hi there\n");
     printf("hi there\n");
     printf("hi there\n");
     printf("hi there\n");
     printf("hi there\n");
     printf("hi there\n");
     printf("hi there\n");
     cls();
}
