MSVS 2017: Resoure Editor RC2104: undefined keyword or key name: TBS_NOTIFYBEFOREMOVE

Question

Had a project that worked fine, edited the resources all the time. This time I went in via right click, edit file, removed the IDR_MAINFRAME_256 toolbar references since going to just use one toolbar. However, after saving the file and going back in, now it won't open giving the subject message RC2104: undefined keyword or key name: TBS_NOTIFYBEFOREMOVE

I did a comparison of changes (including everything in the project), there are no include or other changes, just the two items I took out that referenced IDR_MAINFRAME_256. I can compile it fine, just can't open resource editor. What the heck happened and how do I clear it?

TIA!!

Answer 1

I don't know the ultimate answer, but one thing that works is adding #include <windows.h> to the resource.h file.
