• John Paterson sprintf depreciated... so what do we use?

    Now I know that print formatting is available through stream operators, but how can this be used when printing to strings- i cant find anything in std::string (or am I missing something) and I presume there is no inherent method of using string << int etc. Any ideas Thanks >> The way to do this in C++ is std::stringstream .

  We are about to embark on upgrading from 6.0 to 2003 (and possibly 2005 to follow shortly afterwards). We are fairly sure this will give us some nasty headaches through compiler changes, but what we'd like to know is will we get a more XP-like look to our UI through compiling it with the newer libraries - The project uses MFC.

• Roman K "MFC80D.DLL was not found" Error?

  I have an project that was originally developed as a C++ 7.1 native application.  I converted it to VC++ 8 and kept it a native application and it worked fine.  This project has always made use of MFC as a statically linked library. I now want to make use of the CLR.  The first step in doing this is to change the use of MFC to shared dll.  When I do this (with no other changes) my application gets the "MFC80D.DLL was not f ...Show All

• Rakhee "Correct" Workerthread Termination

  Hello, I have used worker threads for a long while and yet always had and still have problems with the "correct" way such threads should be killed for premature termination. They may have files open, are in the process of allocating global memory or doing any number of other things. The closest I got to "correct" is to signal the worker thread through it's priority if it's services are not required anymore for terminati ...Show All

• gaulind CDialog::DoModal asserting in CWnd::DestroyWindow

  To Brian and Martin, who were involved in helping me out with this , please don't shout at me... This thread does follow on from that post - and I'm now investigating refactoring a static library which contains a few MFC classes into a shared DLL - using __declspec(dllexport) to export functions and classes that will be needed across all facets of the solution that need the shared functionality. I've looked all over the place for an ans ...Show All

  Hi guys, I'm trying to get an installer of our product working.  I've finally gotten it compiling and running under VS2005.  For various technical and political reasons, I have to use NSIS as our installation technique.
