对话框实现伸缩窗口功能问题？？

[ponydph]

static CRect RectLarge;
static CRect RectSmall;
if (RectLarge.IsRectNull())
{
CRect rectSeparator;
GetWindowRect(&RectLarge);
GetDlgItem(IDC_SEPARATOR)->GetWindowRect(&rectSeparator); //分割线标志

RectSmall.left = rectSeparator.left;
RectSmall.top = RectLarge.top;
RectSmall.right = RectLarge.right;
RectSmall.bottom = RectLarge.bottom;


}

SetWindowPos(NULL,RectSmall.left,0,RectSmall.Width(),RectSmall.Height(),SWP_NOMOVE|SWP_NOZORDER);
///分割线是竖线，即实现隐藏左半边部分的对话框，我用SetWindowPos函数，设置坐标X，为RectSmall.Left为
什么没有起作用？？？
谢谢

你的RectSmall的top和buttom不该都设置为RectLarge的吧
最后一句改为
RectSmall.bottom = rectSeparator.bottom;试试
