          case IDREFRESH :

	 case WM_DESTROY:
		  EndDialog(hTcpDlg,0);

     }
     return FALSE ;
}

推荐答案

您可以将GetTCPConn()函数拆分为两个函数:

• 一个初始化函数，用于初始化要在WM_INITDIALOG上调用的控件.
• 一个更新函数，用于在控件中填充要在IDREFRESH上调用的内容.

You may split your GetTCPConn() function into two functions:

• An init function that initializes the controls to be called upon WM_INITDIALOG.
• An update function that fills the controls with content to be called upon IDREFRESH.

我再次调用了相同的函数，并且起作用了..

I called same function again and it worked..

您不能简单地再次从IDREFRESH调用GetTCPConn(hTcpDlg);吗?

Couldn''t you simply call GetTCPConn(hTcpDlg); again from IDREFRESH ?
