Ii. examples
Example 1: Manually adding a control to the resource window Idc_progress1
CProgressCtrl *MYPROCTRL2 = (CProgressCtrl *) GetDlgItem (IDC_PROGRESS1);
Myproctrl2->setrange (0,100);
for (int i = 0;i<100;i++)
{
Myproctrl2->offsetpos (1); This code is equivalent to the next two sentences, the Fixed step 1 update display, the function can also be implemented as follows: Myproctrl2->setpos (i);
Myproctrl2->setstep (1);
Myproctrl2->stepit ();
Sleep (100);
}

Example 2: The resource window does not increase and the progress bar is generated directly from the code
CProgressCtrl Myproctrl;
CRect Rect,prorect;
GetClientRect (&rect);
prorect.left = rect.left + rect. Width ()/2-100;
prorect.top = rect.top + rect. Height ()/2-20;
prorect.right = Rect.right-rect. Width ()/2 +;
Prorect.bottom = Rect.bottom-rect. Height ()/2 +;
//ws_child| ws_visible| Pbs_smoothreverse
myproctrl.create (ws_visible,prorect,this,99);//create location, size
Myproctrl.setrange (0,100);
int i;
For (i = 0; i <; i++)
{
Myproctrl.offsetpos (1);
CString str;
Str. Format (_t ("%d%%"), i); Percentage
(GetDlgItem (IDC_STATIC1))->setwindowtext (str);
