Set the name of a thread created with SetTimer() API

I create a Windows timer using t开发者_开发百科he following

FHandle := SetTimer(0, 0, 1000, TFNTimerProc(@TMyClass.MyMethod));

Is this thread shown in the Delphi "Threads" window. If Yes how I can get this Thread ID?

There is no thread created by that function. The OS calls the callback function when your program handles the wm_Timer message. It's called from within the context of the same thread that called SetTimer, so the thread had better have a message pump. (It you're calling this from the main VCL thread, then the message pump is provided for you by the TApplication class.)

Furthermore, SetTimer doesn't return a handle. It returns a timer ID.

And finally, unless that method is a class static method, it won't work the way you hope. If the signature of the callback matches what SetTimer expects you to provide, you won't need a type cast, so if you needed to type-cast the function pointer to make the compiler accept your code, you probably got it wrong.

SetTimerdoes not create a thread but does call the specified function in the context of the main thread after the specified timeout. If you don't pass a callback function, SetTimer posts a WM_TIMER message to your main window class.

See the MSDN reference for SetTimer for more information.
