在下一个对话框的列表框中设置字符串 [英] Set String in the List Boxes in the Next Dialog

问题描述

您好
我想在mfc和主对话框中编写一个程序，如果您单击一个按钮，我想使用

Hi
I want to write a program in mfc and in the main dialog if you click a button I want to display another dialog using

sampledlg.DoModal();

显示另一个对话框 我想在其中使用:

and in it I want to use:

listbox.AddString(L"str1");

但出现错误，我无法添加字符串.请告诉我为什么?
这是用DoModal()函数制作另一个dlg吗?

but I get an error and I can not add strings. please tell me why?
Is this for making another dlg with DoModal() function?

thanks.

推荐答案

而不是DoModal()，如果您的初始化不存在，请尝试将其放置到虚拟BOOL OnInitDialog()中.很久以前，我最后一次使用MFC，但是我认为在调用DoModal()时，并不是所有的基础资源(HWND s)都被创建，但是当InitDialog()运行时，它们已经存在了(包括您的列表框).我在启动MFC时常犯的另一个常见错误是，我没有将MFC对象附加到DoDataExchange()和DDX_Control()或InitDialog(中的基础控件(HWND s)上. SubClassDlgItem().

Instead of DoModal() try to put your initialization to virtual BOOL OnInitDialog() if its not there already. It was long ago I used MFC for the last time but I think that at the time DoModal() is called not all the underlying resources (HWNDs) are created, but when InitDialog() runs, they already exist (including your listbox). Another common mistak I made a lot of times when I started MFC is that I haven''t attached the MFC objects to the underlying controls (HWNDs) in either DoDataExchange() with DDX_Control() or in InitDialog() with SubClassDlgItem().
