I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server.

Encoding Array.String > Array VB2005

May 27, 2009

I've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.

The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.
