对话框界面裁剪，SetWindowPos函数，部分显示

我想让一个对话框只显示其右上1/4的东西，就是只显示2，怎么做？

我在其他地方看到了只显示1可以用SetWindowPos实现，这个函数能实现显示2吗？
void CVideoNetDlg::OnButtonClip()
{
// TODO: Add your control notification handler code here
CString str;
if(GetDlgItemText(IDC_BUTTON_CLIP,str),str == "<<")
{
SetDlgItemText(IDC_BUTTON_CLIP,">>"); //IDC_BUTTON_CLIP按钮的ID
}
else
{
SetDlgItemText(IDC_BUTTON_CLIP,"<<");
}

static CRect rectLarge,rectSmall;
if(rectLarge.IsRectNull())
{
CRect rectSeparator1;
GetWindowRect(&rectLarge);
//IDC_SEPARATOR就是1和2中间那条线的ID
GetDlgItem(IDC_SEPARATOR)->GetWindowRect(&rectSeparator1);
rectSmall.left = rectLarge.left;
rectSmall.top = rectLarge.top;
rectSmall.right = rectLarge.right;
rectSmall.bottom = rectSeparator1.bottom;
}

if(str == "<<")
{
SetWindowPos(NULL, 0, 0, rectSmall.Width(), rectSmall.Height(),
SWP_NOMOVE|SWP_NOZORDER);
}
else
{
SetWindowPos(NULL, 0, 0, rectLarge.Width(), rectLarge.Height(),
SWP_NOMOVE|SWP_NOZORDER);
}

}

试试这个

CRect rcOld;
CRect rcNew;
GetClientRect(&rcOld);
rcNew.left = rcOld.right - rcOld.Width()/2;
rcNew.right =rcOld.right;
rcNew.top = rcOld.top;
rcNew.bottom = rcOld.bottom - rcOld.Height()/2;
HRGN hrgn = CreateRectRgnIndirect(rcNew);
SetWindowRgn(hrgn,true);

lz试试看把
rectSmall.left = rectLarge.left;
rectSmall.top = rectLarge.top;
设置为2的左上角的值

当然了，
rectSmall.right = rectLarge.right;
rectSmall.bottom = rectSeparator1.bottom;
是2的右下角
