• Visual C++ Visual Studio .NET 2003/2005 VC debugger does not handle opaque type inspection correctly, a regression from VC 6

  I believe I have found a bug in the VS 2003/2005 debugger. When you compile the below C code and step into the create_two or function_two routines, the debugger gets the opaque type incorrect. Visual C 6 did not suffer from this problem. It appears that the debugger IDE binds the first struct definition to the opaque type across all files, but this is incorrect. Struct definitions are scoped on a per file basis. NOTE: The source can be down ...Show All

• .NET Development Garbage Collector and Memory Release

  When the garbage collector determines that an object is no longer required, does it actually release memory from the application or not I have noticed personally that starting another application leads to a drastic drop in memory held by managed applications. Does this mean that 1) garbage collection only takes place when there is memory pressure or 2) that garbage collection is internal to the application(only releases memory inside ...Show All
