Good news, everyone! We have finished integrating VisualGDB with SourceVu, so you can now easily view online documentation and examples for commonly used functions by just pressing F1 in Visual Studio, or clicking at the SourceVu link at the bottom of the quick info tooltips:
To use the new functionality, update to VisualGDB 6.0R5 and you are all set! As a bonus, the new build fixes a few glitches with the high-DPI displays, adds support for the latest VS preview, and introduces various other fixes across the board.
