How do I end a thread?

I used the sample code below to execute the thread:

procedure Form1.Button1CLick();
var vThread : Integer;
begin
      vThread := Thread.create(False);
end;

When I click Button2, the Thread should stop... How can I do that?
I thought of using ExitThread but I dont know how to use the GetExitCodeThread function to get the exit code of the thread.

PLease help... thanks

To stop a thread,
  1) Buy ExEx premium services
  2) Search in Delphi TA for Thread stop
  3) Click on this link from the search results

hi ...Snehanshu
  thanks fo replying...

I did the example you have in your 3rd comment, but I always get "Access Violation" after executing the program. You see, my Thread (.execute) is located in Unit2...... But I am stopping it from unit1...
I have included the Unit2 in the uses of  Unit1... but still I receive the access violation.

LORD_CHO,

  I do not know too much about threads, but can you provide code related to your thread in both units (of how you are creating and terminating )?
  I'll try, but if not me, others might be able to help.

Shehansu Hi seen you around alot lately,

Any way LORD_CHO how about you try wrapping a try except block around the code in Shehansu's code. This may help prevent the violation from occuring. Use the red dot things to trace the place where the violation is occuring but first of all use the try except. You will still see the error in delphi unless you turn stop on delphi exceptions off:

goto Tools-Debugger Options- Language Exceptions - Turn off stop on delphi exceptions

Regards,
