to be more constructive...
I use the dataset designer in Winofrms and copy the dataset files and code into the VWG project, do some find and replace, then it works OK.
But, can't use the VWG designer for any dataset/bindingsource etc and have a useful outcome.
IMO, this, and other bugs, is far more important than the completion of the theme designer, an opinion expressed by others.
