RE: thread & dialog based application

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

You may not directly access main thread window controls from within any other
thread. Instead you should PostMessage user defined messages to notify the
main thread that it has to change something (edit control content) in your
case.

Hi

I want my threads to write some text in edit boxes, but i got no idea
how to get access to control values of that boxes.. Thread is
declareted in main dialog class.

I mean my thread is :
UINT __cdecl threadA(LPVOID pParams)
{
struct userInterface * ptr;
ptr = (struct userInterface *) pParams;
for(;;)
{
WaitForSingleObject(bFnsz,INFINITE);
ptr ->strTh1 = ( _T("AAA "));
m_th1.ReplaceSel(ptr ->strTh1); // Here i got error. m_th1 is
declareted in main dialog class.

ReleaseSemaphore(aFnsz,1,NULL);
}
return 0;
}

thx in advance for help
