A sample of use

Below is the part of the WM_PAINT (OnDraw) event handler:

		
	#include "code128.h"
	
	void OnDraw(HDC dc)
	    {
	    // ========================================= 
	    // =         Start barcode drawing         = 
	    // ========================================= 
	    // The instance of the class 
	    CODE_128::CODE128 Code128;
	    // The horizontal resolution
	    // of the output device
	    int xres=::GetDeviceCaps(dc,LOGPIXELSX); 
	    // The vertical resolution
	    // of the output device
	    int yres=::GetDeviceCaps(dc,LOGPIXELSY);
	    // An initialization of the instance of the class
	    Code128.SetXResolution(xres);  
	    Code128.SetYResolution(yres);
	    
	    // Let us set the one module width =
	    // 0.25 millimeters
	    Code128.SetOneModuleWidth(0.25);
	    
	    // Our barcode will contain the number  
	    // 123456789012345678901234567890 
	    Code128.SetCodeString("123456789012345678901234567890");
	    
	    // Now we are ready to draw the barcode
	    // Draw the barcode!
	    Code128.Draw(dc,100,200,50,RGB(0,0,255)); 
	    // That is all! 
	    // ========================================= 
	    // =          End barcode drawing          = 
	    // ========================================= 
	    }
