My solution generates some source and header files, which are placed into Debug folder and get compiled later (header files are included into source files in the solution). Is there a way to add these files into Open File in Solution dialog? If not, I would suggest to add such a feature - rather than navigating through folders in Explorer it would be much more convenient to search such files by name.
VA Options -> Projects -> File handling -> if solution is not empty
When you next open any files from your debug folder, VA will parse all other source file in that folder. The tooltip for this checkbox will elaborate the process a little bit.
Consider adding the generated files to the projects that you access them from (change the build rules for the added source files so that they are not compiled with the rest of the project if necessary).
