    Visual Studio 8 IDE: intellisense (?) says 'symbol undefined'?

    When I right-click on some function or class name in my source code, and choose 'Go To Definition', lately I'm getting "Symbol 'FooBar' not defined' more and more often.

    Is there some way I can get it to update or reparse my code? (This feature is part of VS8's intellisense, right?)

    Have you already tried deleting the .ncb file and reloading the project?

    Hmm no, I tried that, as well as other temporary files (.suo, .user), closing & reloading my project, but it still doesn't find certain labels (which are certainly there).

    Is IntelliSense supposed to rescan automatically? Or does this take a while before that happens in the background or something?

    Intellisense is rather prone to malfunctioning, it's just the way it is. Your choices are to suck it up, or shell out for something like Visual Assist X. Apparently it's meant to be better in VS2010, but I haven't tried it.

    VS10 Beta is poor, slow and unreliable. I wouldn't recommend it now.
    We'll see how IntelliSense turns out in the final version, but don't bet on it being bug-free.

    If you delete the NCB, as has been said, it should rebuild the entire database. I have found that in both 2003, and 2005 IntelliSense is very bad at using outdated headers thus giving you incorrect prototypes.

    You may also want to delete the PDBs for your project. I've heard that 2008 has a big problem with the PDBs.

    I haven't had that many problems with the PDB files. But perhaps it is because my projects have been too small scale (using VS2008).
    NCB files, OTOH, is a big problem and IntelliSense just plain lacking.
