Problem with TStringList on thread

[JackT 0]

I am creating a string list on a thread inside a function like this

 

class AQNI : public TThread

{

//Some definitions

}

 

AQNI * mythread;

 

bool AQNI::ReadXMLData

{

     TStringList * ATB = new TStringList();  //Access violation occurs here the 2nd time the thread is created

{

//DO SOME STUFF

}

__finally

{

delete ATB;

}

return true;

}

 

The first time the thread is created everything runs fine. After I have finished with threaded object I destroy the thread and wait for a command and to start a data collection loop at which point I Free and delete mythread.

However when I recreate my thread and call the ReadXMLData function when I try to create a fresh string list the whole thing falls over with an access violation. I am surprised the code is broken because it was previously working. 

 

The exception is ocuring in BorlndMM ( Borland Memory Manager )

There is not enough information to diagnose your problem. How are you creating and destroying the thread? Are you really destroying the thread TWICE before starting a new thread? What is your thread code doing besides creating the TStringList? We need to see a more complete code example.
