我的任务
分享Dlg.DoModal()函数中止运行。。。
我的代码本意是，通过点击主窗口菜单项，经消息响应函数OnDrawBall() 调出对话框
CBallDlg对应的弹出窗口为：
但调试到这一个响应函数的DoModal时，中止运行
求问哪里出错了
void CMy2012302590190Doc::OnDrawBall()
{
// TODO: Add your command handler code here
CBallDlg dlg;
if(dlg.DoModal()==IDOK)
{
}
}CBallDlg对应的弹出窗口为：
但调试到这一个响应函数的DoModal时，中止运行
求问哪里出错了

嗯，很有道理，我按照这样一步步脱掉引用，发现OnInitDialog函数加进来就出之前的错，不加进来就好了。进一步单步调试找到了原因，就是这一句出问题了：
这是结果，非常感谢！
m_spin.SetRange(-200,200);这是结果，非常感谢！

void CBallDlg::OnPaint()
{
CDialog::OnPaint();// 画所有控件！！！
// 下面这个函数有问题;
Draw();// 画IDC_BALL
}

试过了，还是一样的错误，CBallDlg定义的dlg调用DoModal函数失败[/quote]
可以的话发工程给我吧，试试

Dlg.DoModal()函数中止运行，这Domodal函数本身肯定没有问题，在你对话框CBallDlg类哪出错了，建议把这CBallDlg类的全部自己写东西注释了，一个一个的打开，看哪里出问题里，onpaint里是重点
