• JordanS C2664 cannot convert from 'System::String ^' to '_bstr_t'

  This may seem silly, but how do you convert from a managed System::String to BSTR or _bstr_t or ANY other string (const char *, etc.).  This would be required to call an old COM interface from a managed C++ app. If this has already been answered I apologize.  I searched but did not find anything. Helper functions and constructors and member operators have been known to help.  For example in the d ...Show All

• skop Progress Bar assistance

• koo9 Visual C++ compiles much slower on dual core processor

  The Background:  I recently upgraded from a 2GHz AMD Athlon machine to a 3.2GHz Pentium D dual core processor, thinking that my Visual C++ (.NET 2003) compile times would decrease significantly.  In fact, it went the other way round.  One of my library projects requires 11 minutes to compile on the AMD machine, but takes 25 minutes on the dual core machine.  My entire set of projects compiles in about 4 ho ...Show All

• VB Technical Support Corrupt Builds After Cancel

  Our team has a ~50 project solution with a few dlls, lots of libs, and three executables. If I do a build solution, and at any point during the build hit Control-C to cancel it, whatever is being built at the time I hit the button is now corrupt. It looks like it leaves the partially created .obj, .exe, or .dll around and doesn't detect that it only got halfway through. Is this a common symptom Is there some known fix (MSDN and google searches ...Show All
