Text Output Screen

Environment: VC6, NT, WIN2000, WIN9x,

This is a set of functions (packaged in a DLL) that allows for easy text output to a text window.

Example Usage

Here's an example code snippet on using these functions.
#include "stdafx.h"
#include "screen.h"

int main(int argc, char* argv[])
{
 // Show Screen displays a new screen and returns a handle to it
 int h=ShowScreen(30,10,"Example!",0,255,5,5,15);

 // SetScrRedraw sets the type if redrawing (true=RedrawWindow or 
 // false=WM_PAINT message)
 SetScrRedraw(h,true);

 // pf works the same as printf except that it takes the screen 
 // handle (returned via ShowScreen) as the first argument
 for(int i=0; i<3000; i++) pf(h,"Var i = %d\n",i);

 return 0;
}

Function Prototypes

Here are the main functions exported from the DLL.
int ShowScreen( int w,int h, // Window size in char (X,Y) 
 char *Banner=0, // Window Title
 int colB=0, // Background color
 int colT=0x8080ff, // Text color
 int x=0,int y=0, // Window pos
 int fSize=10); // Font size

void DestroyScreen(int h);
HWND GetHwnd(int h);
void ClrScr(int h);
void SetPos(int h,int x,int y);
void SetChar(int h,int x,int y,char c);
void SetScrRedraw(int h,int r);
