How to implement progressbar(to show progress) using threading concept in win 32?

Question

I am trying to show a progress bar while my process is going on...in my application there will be a situation where I gotta read files and manipulate them(it will take some time to complete)..want to display a progress bar during this operation..the particular function I am calling is an win 32 ...so if you check my code below i am upto the point of creating the progress bar in a dialog window and creating a thread Now I dont know how to post the message and where to get the message and handle...Please help me..thanks in advance

    //my  function
    int Myfunction(....)
    {
     MSG msg;
     HWND dialog = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE,
         600,300,280,120,NULL,NULL,NULL,NULL);
     HWND pBar =  CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE,40,20,200, 20,
           dialog,(HMENU)IDD_PROGRESS,NULL,NULL);


      while(GetMessage(&msg,NULL,0,0))
{
    TranslateMessage(&msg);
     Dispatch(&message);
}
SendMessage(pBar,PBM_SETRANGE,0,MAKELPARAM(0,noOfFile));

     HANDLE getHandle = CreateThread(NULL,NULL,(LPTHREAD_START_ROUTINE)SetFilesForOperation(...),
        NULL,NULL,0);

    }


    LPARAM SetFilesForOperation(...)       
    {

     for(int index = 0;index < noOfFiles; index++)
     {


      *checkstate = *(checkState + index);
      if(*checkstate == -1)
      {
       *(getFiles+i) = new TCHAR[MAX_PATH];
       wcscpy(*(getFiles+i),*(dataFiles +index));
       i++;

      }
      else
      {
       (*tempDataFiles)->Add(*(dataFiles+index));
       *(checkState + localIndex) = *(checkState + index);
       localIndex++;
      }

      PostMessage(pBar,PBM_SETPOS,(WPARAM)index,0);
     }
    }

EDIT2: using AFXTHREAD

//instead of createthread i used AfxBegin thread
    ptrThread = AfxBeginThread((AFX_THREADPROC)SetFilesForOperation(pBar,checkstate,checkState,noOfFiles,i,getFilesforcompression,dataFiles,&tempDataFiles,localIndex),
        NULL,THREAD_PRIORITY_ABOVE_NORMAL,NULL,NULL,NULL);


for(int index = 0;index < noOfFiles; index++)
    {

        MSG msg;
        *checkstate = *(checkState + index);
        if(*checkstate == -1)
        {
            *(getFilesforcompression+i) = new TCHAR[MAX_PATH];
            //*(getFilesforcompression+i) = L"C:\\Documents and Settings\\rakesh\\Desktop\\try2_Extracted";
            wcscpy(*(getFilesforcompression+i),*(dataFiles +index));
            i++;

        }
        else
        {
            (*tempDataFiles)->Add(*(dataFiles+index));
            *(checkState + localIndex) = *(checkState + index);
            localIndex++;
        }


        //PostMessage( pBar, PBM_SETPOS, (WPARAM)index, 0 );
        PostMessage( pBar, PBM_SETRANGE, 0, MAKELPARAM( 0, noOfFiles ) );
        //PostMessage( pBar, PBM_SETPOS, (WPARAM)index, 0 );
        PostMessage( pBar, PBM_STEPIT, (WPARAM)index, 0 );
        PostMessage( pBar, MSG_PROGRESS_VALUE, 0, 0 );


        while(1)
        {
            while(PeekMessage( &msg, NULL, NULL, NULL, PM_NOREMOVE))
            {


                AfxGetThread()->PumpMessage();
                Sleep(10);




        }

Answer 1

I changed the Postmessage in the thread call and it worked...

while(PeekMessage( &msg, NULL, NULL, NULL, PM_NOREMOVE))
                {


                    AfxGetThread()->PumpMessage();
                    Sleep(10);
}
