 Progress bar not showing visual progress

Hi All,

I'm using evc 4.0. i have created a dialog and inside that
i have put one progress bar control t design time. I have
initialsed like this:

INITCOMMONCONTROLSEX    initCtrls;
initCtrls.dwSize = sizeof(INITCOMMONCONTROLSEX);
initCtrls.dwICC = ICC_PROGRESS_CLASS ;
if (!InitCommonControlsEx(&initCtrls))
{
MessageBox (NULL,_T("error in creation"), _T("Alert!!"),
MB_OK);
return false;

Quote:
}

Get the handle to the control
TempHandle = GetDlgItem(hDlg,IDC_PROGRESS1);
SendMessage(TempHandle,PBM_SETRANGE,0,100);
SendMessage(TempHandle,PBM_SETSTEP,1,0);

Now i have tried using STEPIT like this
///////////////////////////
for( int i = 1; i<=100;i++)
{
SendMessage(TempHandle,PBM_STEPIT,0,0);                

Quote:
}

but it didn't show any progress
then i used
///////////////////////////
for( int i = 1; i<=100;i++)
{
SendMessage(TempHandle,PBM_STEPIT,0,0);
SendMessage(TempHandle,PBM_SETPOS,i,NULL);              

Quote:
}

Now what happens is that the progress bar at one strach
get filled and do not show any visual representation of
progressing. The progress bar is full everytime i see to
it. I want to see it expanding one by one. can anyone tell
me whats wrong here.

thankx in advance
-Jim

You don't wont to send the messages in a tight loop.
You have to increment the progress bar putting some time interval
between each two steps, depending on some other info.

As an example, if you know the totale time required, say this is T secs,
do an increment each n = T/100 secs with a timer, for a total of 100
increment.

As another example, if your long process require n sub-process
do an increment each n/100 sub-processes, for a total of 100 increment.

Hi Vincenzo,
Thankx for the feedback. I have already tried the same by
putting delay (Sleep()) in the loop. but strangely for the
whole loop the sleep works all together at one time and
then progress bar came again with same speed and i can't
see that progress. I tried by giving messagebox but
similar to sleep all messages start poping n numbers of
time and then at the last the progress bar is drwan fully
at one go.

any idea?

Sleep(100);
MessageBox(NULL,TEXT("here"),_T("Alert!"),MB_OK);
SendMessage(TempHandle,PBM_STEPIT,0,0);
SendMessage(TempHandle,PBM_SETPOS,i,NULL);

I know if you are inside a window message handler, the window cannot
handle WM_PAINT message, so no refresh can be viewed.
This might hold also for child controls.

So try to
    SetTimer(hWnd, 1, 500, 0);
Then in the WM_TIMER message handler do your
    SendMessage(TempHandle,PBM_STEPIT,0,0);
    SendMessage(TempHandle,PBM_SETPOS,i,NULL);
Note that you may have the need to declare i as global or static.

I have tried with timer also but it didn't worked moreover
the progress is not showing any progress now.

My code is like this. I have a dialog and a progress bar
control has been drwan on that.IDC_BUTTON1 is the button
when pressed i want the bar to be drawn
==============================================
case WM_COMMAND:
if ((LOWORD(wParam) == IDOK) || (LOWORD(wParam)==IDCANCEL))
{
EndDialog(hDlg, LOWORD(wParam));
return TRUE;

Quote:
}

else if((LOWORD(wParam) == IDC_BUTTON1))
{
TempHandle = GetDlgItem(hDlg,IDC_PROGRESS1);
SendMessage(TempHandle,PBM_SETRANGE,0,10);
SendMessage(TempHandle,PBM_SETSTEP,1,0);
SetTimer(hDlg, 10025, 2000, 0);
/*for(i = 1; i<=100;i++)
{
SendMessage(TempHandle,PBM_STEPIT,0,0);
SendMessage(TempHandle,PBM_SETPOS,i,NULL);
Quote:
}*/
}

break;
case WM_TIMER:
MessageBox(NULL,_T("Alert!"),_T("szFinalAddr"),MB_OK);
SendMessage(TempHandle,PBM_STEPIT,1,0);
SendMessage(TempHandle,PBM_SETPOS,i,NULL);
break;

Can u see something missing here?

 Progress bar not showing visual progress
It didn't worked .

I have created a dialog and drawn progress bar control
over it at design time.
 in DLGPROC for that dialog code is:
==========================================
WM_Command :
if((LOWORD(wParam) == IDC_BUTTON1))
{
TempHandle = GetDlgItem(hDlg,IDC_PROGRESS1);
SendMessage(TempHandle,PBM_SETRANGE,0,10);
SendMessage(TempHandle,PBM_SETSTEP,1,0);

SetTimer(hDlg, 10025, 2000, 0);

Quote:
}

break;
case WM_TIMER:
MessageBox(NULL,_T("inside timer"),_T
("szFinalAddr"),MB_OK);
i = i+10;
SendMessage(TempHandle,PBM_STEPIT,1,0);
SendMessage(TempHandle,PBM_SETPOS,i,NULL);
