CreateThread and AfxBeginThread

[tom groezer]

In MFC what is the difference between these functions and what is the fine line calling AfxBeginThread vs calling ::CreateThread

[Hamid Taebi]

See here[^].

The documentation ([^] and [^]) doesn't help, does it? Roughly speaking, you can spot the main difference in the AfxBeginThread overloaded form supporting user interface threads, i.e.:

CWinThread* AfxBeginThread(
CRuntimeClass* pThreadClass,
int nPriority = THREAD_PRIORITY_NORMAL,
UINT nStackSize = 0,
DWORD dwCreateFlags = 0,
LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL
);

The above provides some boiler plate code helping, user interface threads development. :)

MSDN Use AfxBeginThread to create a thread object and execute it in one step. Use CreateThread if you want to reuse the thread object between successive creation and termination of thread executions.

On Windows, all the thread creation methods eventually call ::CreateThread() to create the thread. The difference is, AfxBeginThread() does MFC-specific initialization on the thread. The typical rule of thumb is: Use AfxBeginThread() to create a thread in MFC if the thread will use any MFC objects. Use _beginthreadex() to create a thread if no MFC objects are used but CRT functions are used (including new/delete!). Use ::CreateThread() if just Win32 APIs/objects are used. Also make sure you link to the multithread MFC/CRT libraries!! :) Mark
