12     if(rectLarge.IsRectNull())
13     {
14         CRect rectSeparator;
15         GetWindowRect(&rectLarge);
16         GetDlgItem(IDC_P)->GetWindowRect(&rectSeparator);
17         rectSmall = rectLarge;
18 
19         rectSmall.bottom = rectSeparator.top;
20     }
21     if(str == "收缩<<")
22     {
23         SetWindowPos(NULL,0,0,rectSmall.Width(),rectSmall.Height(),SWP_NOMOVE|SWP_NOZORDER);
24     }
25     else
26     {
27         SetWindowPos(NULL,0,0,rectLarge.Width(),rectLarge.Height(),SWP_NOMOVE|SWP_NOZORDER);
28     }

其中，IDC_P是pictrue空间的标识、、
