Hello – we have an old Visual Web Gui app that we have not edited for about 5 years running at a customer. We are looking to convert this to WiseJ but ran into an issue just debugging it to figure out what it was doing. We even opened the original Upload control sample and get the same error:

“Could not resolve skin resource of type ‘ImageResource’.

It was using their upload control – and I think this may be causing the error as we get the same error when trying to run that small sample.

I know you guys have extensive knowledge of VWG – do you know why we get this error ? We have opened VWG apps int he past to convert them to WiseJ without issue and they still ran fine in the debugger (we had to compare the functionality when we were done with the WiseJ rewrite so we we ended up having to debug the old application to figure out our issues after we recreated it). Visual Studio 2012 VWG:Version=4.5.5701.0
