FeinSoftware presents FeinViewer ™ - an integrated GDI objects viewer for Microsoft Visual Studio .NET 2005 (8.0) Visual C++ Debugger.



FeinViewer provides real-time viewing of GDI objects in your debugger as you are stepping through your code, very much like Watch windows allow you to view the values of your variables.

The great advantage of FeinViewer is that no instrumentation of any kind is required from the developer. No recompiling. No relinking. Just "Go" and view your objects.

FeinViewer displays your GDI objects in resizable, scrollable, scalable (to 32:1 zoom level), floatable and dockable tool windows that are automagically updated on every breakpoint stop. If an image has changed since the last breakpoint, the value and type boxes will be colored in red (just like variables in the Watch windows). If the object is not available at the current breakpoint (out of scope), those boxes will be colored in gray, but you can still inspect the previous content of that object.

New in FeinViewer version 1.1: Added support for icons and cursors. This version is also available in Academic Edition for non-commercial use at a 65% discount! Please download it from our Store page.
