• supersonic_oasis Timing the compiler

  The Visual C++ 2003 linker has an undocumented /TIME option which reports how much time the linker has spent on each phase. Is there a corresponding option for the compiler   It would be helpful to know exactly how long each file took to compile.  I have a 146-file project taking nearly 30 minutes to build; it would be quite helpful to find out where the delays are. The compiler is ultrafast in co ...Show All

• Flyboy compiler bug with templates, VC++2005

  Hi, I think I've found a compiler bug with templates. I've tested this code with VS2003, and VS2005 Beta 2. The following code will produce a warning when compiled, and I can't see any reason for the warning. I've simplified the code as much as possible while it is still producing the warning.

• nathanshih MemoryStream

  This does not work: MyStream is a MemoryStream InsertString = String::Format ("insert into blobtest (blobtest) values ('{0}');", MyStream->GetBuffer()); MyStream->GetBuffer() just returns "System.Byte[]", not the actual data, which is what I want. You can see what I'm trying to accomplish here. Why isn't it working Before I answer this question, I'd like to know how you obtained ...Show All

• cb1024 BeginInvoke help!

  From what I read, BeginInvoke can be used to call functions that take a long time to execute by making them execute on a separate thread.  I wrote a little test program to try this and I cant get it to work.  Forgive me if I have got it completely wrong, i've only moved from 'C' to VC++.NET in the last few months. I have a button that when clicked should run a little delay routine (large_function in external_class) for a couple of seco ...Show All

• Pwrman02038 Mixing Managed and Unmanaged C++

  Hi All, I'm a beginner in this managed C++. Currently, all of our existing system is coded in unmanaged C++ w/ OpenGL. Then, at the moment, there is a need to produce a binary file that is readable both in current C++ and C# (using BinaryReader). With this requirement, I ASSUME that I need to code that file function in managed C++ inside the current system. However, there are a lot of errors coming out as soon as I switch the /clr switch o ...Show All

  I'm porting some code from another environment which defined an dirent.h and had an dirent structure which was used with opendir/readdir/closedir functions...  What is the VC equivalent to these functions, as VC doesn't have the dirent.h, dirent struct and/or the opendir/readdir/closedir functions (or at least I'm not able to find them in the help or in the directories).

  I'm a psychology grad student at Miami U. in Ohio, and I need to come up with a way to create an installer for a program that is a single .exe file.
