Re: CProgressCtrl help needed

Hi,

I am writing a dialog-based mfc application for a smartphone. There is
a dialog in app, which is a login page with username and password
field with OK button. When a user clicks OK button, and tries to
login, I show a progress bar using CProgressCtrl class. In the
background I verify that username and password match. If it matches, I
go to the next dialog and ProgressBar works fine.But, If username and
password do not match, I give error messagebox to user and stay in the
same login dialog. Now, the progressbar should show 0 progress (or
disappear). I set the position of ProgressCtrl to 0 using
m_ProgressCtrl->SetPos(0) . If user enters username & password again
this time, ProgressCtrl should behave exactly as it did earlier(Show
progress blocks while I verify fields in background). But, the
progressbar does not work that way. There is no change in the ctrl and
progress is not shown at all.

My questions:

1) How to hide/show the ProgressCtrl seamlessly as I want in code at
runtime?
2) How to make Progress Control work just like it works in any
browser.

My code:

onOK()
{
     CProgressCtrl *m_PC = new CProgressCtrl;
     m_PC->SetRange(0,100);
     m_PC->SetPos(10);
     m_PC->StepIt();

     // Code to verify username and password. and m_PC->StepIt() every
2 seconds.
     if(username and password valid)
     {

         //Go to next dialog

    }
   else
   {
      // Error message.
      // m-PC->SetPos(0);
   }
return;

}
