急:我用了SetWindowRgn把窗口变成圆角矩形后,窗口上的按纽怎么失效了?

Question

BOOL CXBitmapDlg::OnInitDialog()
{
..................
..................         SetWindowRgn (m_rgn, FALSE);
ShowWindow(SW_SHOW);         m_btnOK.Create......
         m_btnCancle.Create......}
按纽的显示正常,但是点上去没有任何反映,由于这个对话框是DoModal的,只有把程序关了.注释掉SetWindowRgn后,就可以了,但是就没有圆角矩形的效果(这个效果是必须的).
各位高手帮我看看吧,谢谢了!

Answer 1

点上去没有任何反映,由于这个对话框是DoModal的,只有把程序关了 m_btnOK，和cancel
你这两个按钮的消息响应做了吗？？

Answer 2

做了啊,如果把SetWindowRgn (m_rgn, FALSE);注释掉,一切正常(包括按纽)

Answer 3

BOOL CXBitmapDlg::OnInitDialog()
能把这个函数全写出来吗?
