I have it implemented like MEKBarcodeLBL.Text = (MEKScrapLBL.Text).PadLeft(3, '0') This program can also be used as an auditing tool to verify an existing GRID. The program will display the full GRID (ION + RDI + checksum). Now for my question How could I change the code to encode that correctly? Or,Is there another FREE code sample that I could implement to get the code 128 barcode? The GRID Checksum Calculator can be used to calculate the checksum portion of the GRID based on the Issuing Organization Number (ION) and Registration Donor Identifier (RDI) elements. ![]() I found that the barcode generator generator code from here has the  as the check character. With much time searching and looking for what should be in that space and what scans. I have found that this will not scan with the space. When it encodes "002" it outputs "Ì002 Î". I have only found a problem with one barcode. I have been using the code from here to convert three digit numbers to barcodes for scanning in the company I work for. ![]()
