Hi
What is difference betwwen /MD and /MDD( multi threaded debug dll ) in c/c++->code generation
propertis of visual studio ....

A:
They specify which runtime to use. Both use mmulti-threaded dynamic (DLL) runtimes, but the /MDD version uses the debug version and also defines the _DEBUG symbol for you. See this MSDN page for details.

No, there is a difference. If you are doing a release build, you typically use /MD if you are doing a debug build, you use /MDD

Memory allocation/release is handled differently in debug and release DLL. You should not mix and match as it will lead to nasty side effects.

A:
The debug version (MDD) allows you to step into the C and C++ libraries, during debugging. There are additional checks for incorrect heap operations and memory leaks. Having dependencies (eg. DLL) to both the release and debug versions can lead to problems so it is recommended that you stick to /MDD for debug version and /MD for release versions.
For Visual Studio 2005/2008, if your application uses /MDD, but depends on DLLs that are built with the release libraries, you will also need to include the manifest for the release libraries in your project settings.

A:
Programs linked with the /MDd probably won't run on most user machines, since the debug versions of the standard libraries are unlikely to be installed on them.
