Writing Barcodes

Take the following steps to add code to the existing project that will let you to write barcodes:

1.	Start with the program you created in Reading Barcodes.
2.	Click on the "Solution Explorer" tab.
3.	Double-click the "BarcodeTutor" folder to open it.
4.	Double-click the "Resource Files" folder to open it. Then double click "BarcodeTutor.rc" file to open it, then double click "Dialog", and then double click "IDD_BARCODETUTOR_DIALOG"
5.	Now, drag and drop 1 button, and change its properties as follows:
		ID	Caption
	Button3	IDC_WRITE_BARCODE	Write Barcode
6.	From View menu, select "Other Windows" menu, then select "Resource View" menu, then select Dialog, and select "IDD_BARCODETUTOR_DIALOG".
7.	Double click on "Write Barcode" button, and add the following code:

   BARCODE1D Bar1d;
   memset(&Bar1d, 0, sizeof(BARCODE1D));
   Bar1d.uStructSize = sizeof(BARCODE1D);
   Bar1d.bErrorCheck = TRUE;
   Bar1d.bOutShowText = TRUE;

   BARCODEDATA BarData;
   memset(&BarData, 0, sizeof(BARCODEDATA));
   BarData.uStructSize = sizeof(BARCODEDATA);
   BarData.nUnits = BARCODE_SCANLINES_PER_PIXELS;
   SetRect(&BarData.rcBarLocation, 100, 100, 350, 200);
   BarData.pszBarCodeData = "012345678901";
   BarData.nSizeofBarCodeData = (L_INT)strlen(BarData.pszBarCodeData);
   BarData.ulType = BARCODE_1D_EAN_13;

   BARCODECOLOR BarColor;
   memset(&BarColor, 0, sizeof(BARCODECOLOR));
   BarColor.uStructSize = sizeof(BARCODECOLOR);
   BarColor.dwColorBar = RGB(0, 0, 0);
   BarColor.dwColorSpace = RGB(255, 255, 255);

   m_Barcode.SetBitmap(&m_Bitmap);

   L_INT nRet = m_Barcode.Write(&BarData, 0, &BarColor, &Bar1d, NULL, NULL, NULL, NULL);
   if (nRet == SUCCESS)
      AfxMessageBox(TEXT("Barcode written succesffuly"));
   else
      AfxMessageBox(TEXT("Failure during writing linear barcodes"));

8.	Compile and test the program.
