There was discussion here starting last Autumn under the heading:
Error "RC2108: expected numerical dialog constant" after project migration from VS2008 to VS2013
and a recent message suggests it is a bug which isn't fixed in update #2.
I've just started using Visual Studio 2013 in an environment where I don't have access to earlier versions (so the 'use 2010' suggested work-around doesn't help) although the project was imported from a VS 2010 project elsewhere. It has been working for me - until I added a string to the string table using the visual interface, and now the resources don't compile - and in fact I can't even see them in the resource view - only as text.
(Several dialogues are producing the RC2108 error, and the lines identified are more to do with text controls than bitmaps.)
How do I continue work on the project?
