Writing Barcodes
Take the following steps to add code to an existing project that will let you to write barcodes:
1. |
Start with the program you created in Reading Barcodes. |
|
2. |
Define the following global IDs in Ezfunc.h in the BarcodeTutor directory: |
|
#define IDM_WRITE_BARCODES
201
3. |
Edit EZFUNC.RC file in the BarcodeTutor directory and add the following lines: |
MAIN_MENU MENU
BEGIN
...
...
MENUITEM "Write Barcode" IDM_WRITE_BARCODES
END
4. |
In the MainWndProc procedure, add the following code to the switch statement for WM_COMMAND: |
case IDM_WRITE_BARCODES:
{
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);
L_INT nRet = L_BarCodeWrite(&LeadBitmap,
&BarData,
&BarColor,
0, &Bar1d, NULL, NULL, NULL, NULL);
if (nRet == SUCCESS)
InvalidateRect(hWnd, NULL, TRUE);
else
MessageBox(hWnd, TEXT("Failure during writing linear barcodes"),
TEXT("Error!"), MB_OK);
}
break;
