• .NET Development socket.Receive() on blocking socket throwing WSAEWOULDBLOCK exception?

  I'm using a UDP socket for network communication with socket.Blocking == true and SocketOption(ReceiveTimeout) set. After several thousand packet exchanges, socket.Receive() starts throwing WSAEWOULDBLOCK (SocketException.ErrorCode == 10034) and seemingly continues to do so indefinitely about every second or third call to socket.Receive().   Can someone shed some light on what might cause socket.Receive() to throw a WSAEWOULDBLOCK exception on a socket with Blocking == true I wouldn't expect a WSAEWOULDBLOCK exception on a blocking socket. This is happening with .Net 2.0 Beta2 on WindowsXP Pro with service pack 2 (and updates). T ...Show All

• .NET Development Can 1.1 and 2.0 framework coexist on the same box?

  I'm trying to get my legacy asp.net (1.1/C#) apps to play nice with future 2.0 development. I can get either the 1.1 stuff to run or the 2.0, but not at the same time.  If the 1.1 apps are working the 2.0 work returns errors that tell me that the frameworks are trying to use the same process and that this can't work. If the 2.0 app works then the 1.1 error out. I suspect that this is an IIS configuration issue, but being weak in iis I can't seem to find a solution. I was advised to look at the App Pool for the individual web apps on by server.  The 2.0 apps show as belonging to the 2.0 pool and the 1.1 apps go to the default poo ...Show All

• Visual C++ read struct from file

  this is a beginner programmer questions, at least i think so. CFile::Read( void* lpBuf ,UINT nCount) i can pass a struct (first param) and the length of that struct (second param) and then i will have a populated struct. How can i do the same thing with a managed c++ function The size of an int is 2, size of a double is 8, and a long is 4, how can i adjust my struct that i am reading in to account for this offset You can just use CFile in managed C++, although I would suggest you should use fstreams instead. I would be more inclined to write the different parts of the struct explicitly though, ...Show All

• Visual C++ Performance problems after porting to VS 2005 from 2003, native C++ code vs STL.

  After porting code from studio 7.1 to 8.0 beta 2, performance (function execution time) decreesed twice. In each two cases code was compiled with max speed optimisation. I tried each useful in my case compiler feature for increasing performance, and nothing helps, 7.1 still x2 faster. Code use basic STL tamplates such as vector, map, iterators, heap functions and nothing else. Please help to understand this fenomenal.     Thanks a lot Maks for taking the time to report the issue.
