Re: Thread Function and access

I have a written a Thread class (CMyThread) and have a
question
concerning the Thread Safety.
The reason for using a Thread is because i need to check
the Version of
Application (multilanguage) online by downloading the
version string.
Normally this action takes several seconds.

So i decided to call the Run() method of CMyThread, for
example:
Run("Connection failed", "New Version available", "You're
using the
latest Version" ...);

For easy explanation i will use only one string in the
following class.
My question is, if it's safe to access this.m_msg in the
Run Method. Or
is there any way to tell the Thread to call a method of my
CMyThread
after (!) executiuon to display the version check result?!

Thanks for any answers and best regards

class CMyThread
{
  private string m_msg;

  bool Start(string msg)
  {
     // Save string for later access in Run Method
     this.m_msg = msg;
     _beginthreadex(NULL, 0, &Starter, this, 0,
&m_ThreadID);
  }

  // The one and only Thread Function for performing some
work
  unsigned Run()
  {
     // Is it safe to access this.m_msg here?!
     // For example:
     MessageBox(NULL, this.m_msg.c_str(), "", NULL);
     // or...
     this.m_msg = "some text";
     // ...
     return 0;
  }

  static unsigned __stdcall Starter(void* pVoid)
  {
     CMyThread *pInst = (CMyThread*)pVoid;
     unsigned iRet = pInst->Run();
     _endthreadex(iRet);

     return iRet;
  }
};
