Re: Thread Abort

Actualy I know about this API, But I don't know can I call it from my C#
application,How HANDLE define in C# ? I didn't find any example in C# doning
that,I will be so glade if you show me the way .

BOOL TerminateThread(
HANDLE hThread,
DWORD dwExitCode
);

Belive me I have a very good reasone to do that, since I work with hardware
and I can't wait until Abort finish his job, Abort function takes long time
to finish , spicialy in the scenarios I minsioned before , which is my
problem .
