Although this posting is old, it still merits a response. Someone else may have a similar issue and want to know what to do.
You basically have one of two options:
1- Draw the barcode symbols yourself using Graphics functions, but you will have to learn the algorithm for that or use a library that draws the barcodes on images like one described in this article
2- Use a barcode font which converts text to barcode symbols. You can then print them or convert them to images depending on your project's needs. The main disadvantage is the application will only work where the font is installed.
