BarcodeLib – ported to Compact Framework

CodeProject: Barcode Image Generation Library ported to Compact Framework

I got a request for a barcode image generator for Windows Mobile. Fortunately there are some libs out there including the source code and I decided to test to port barcodelib by Brad Barnhill hosted at the famous CodeProject site here.

How Was It Done

I downloaded the code, started a new SmartDevice Class Library project in VS2005 and copied the source files into the project dir and started adding the existing code files. I did not start with the original project files, as they were created with VS2008 and used the full framework in version 3.5.

After some builds, code changes, adding conditional compiles and one cfhelper class, the class compiled fine for Compact Framework 2. I had to remove (conditional compile options) most of the BarcodeXML stuff, as these are not? portable that easily to CF2.

C#
            using (Pen pen = new Pen(ForeColor, iBarWidth))
            {
#if !WindowsCE
                pen.Alignment = PenAlignment.Right;
#endif
                while (pos < Encoded_Value.Length)
                {
                    if (Encoded_Value[pos] == '1')
#if !WindowsCE
                        g.DrawLine(pen, new Point(pos * iBarWidth + shiftAdjustment, 0), 
			new Point(pos * iBarWidth + shiftAdjustment, Height));
#else
                        cfHelper.myDrawLine(g, pen, new Point(pos * iBarWidth + 
			shiftAdjustment, 0), new Point(pos * iBarWidth + 
			shiftAdjustment, Height));
#endif

and here is my helper:

C#
using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;

namespace BarcodeLib
{
    static class cfHelper
    {
        public static void myDrawLine(Graphics g, Pen p, Point p1, Point p2)
        {
            g.DrawLine(p, p1.X, p1.Y, p2.X, p2.Y);
        }
    }
}

Then I added a BarcodeLibTest smart device Windows Application project using the new BarcodeLib and was able to get barcodes printed on screen and save the images to files.
