I have gone thru the forum but could not get or understand
My requirement
To read a blob field stored in a mysql database using rdc and set it as a background image of a label field can anyone help please
There is nothing special with blobs. You just need to send an array of bytes as the value. You can use the two utility methods in DBRequestManager ImageToBytes and BytesToImage to convert an image to an array of bytes and back to an image.
