IntroductionSome days ago, someone asked me if it is possible to rename threads in the VC debugger. Because I worked at a multi threading project myself those days, I was very interested in realizing this idea. Some Google group searches later, I had a solution that is short and easy. Because this could be very helpful for everyone working on applications with many threads, I publish it here. There isn't much to understand except, that the VC debugger gets the information about a thread's name via the exception #0x406D1388. I put the necessary call into a simple function. Here is the code: // // Usage: SetThreadName (-1, "MainThread"); // typedef struct tagTHREADNAME_INFO { DWORD dwType; // must be 0x1000 LPCSTR szName; // pointer to name (in user addr space) DWORD dwThreadID; // thread ID (-1=caller thread) DWORD dwFlags; // reserved for future use, must be zero } THREADNAME_INFO; void SetThreadName( DWORD dwThreadID, LPCSTR szThreadName) { THREADNAME_INFO info; { info.dwType = 0x1000; info.szName = szThreadName; info.dwThreadID = dwThreadID; info.dwFlags = 0; } __try { RaiseException( 0x406D1388, 0, sizeof(info)/sizeof(DWORD), (DWORD*)&info ); } __except (EXCEPTION_CONTINUE_EXECUTION) { } } You just have to call Have fun with that tiny tool ;)
