oh, this's true. but I want to to know if there is a way that I can adding data out of the OnInitDialog() function, which means if I can let the listbox object exsit before I fill it up with the data, thus I can update and add different data when necessary at any time and any where. would you give me some suggestion?
thank you!

Thank you very much. I want to know if I can create a way to let the listbox object exsit before I use it which like I can declare an array without initializing, but I can assign data for it when necessary. Would you give me some sugestion? thank you!

Oh, yes, When I move the part of adding data to the OnInitDialog() function, the programm can work constrainedly, but this is not the result I want, which means I have to add some unrelative parts to the Dialog class. Is there a better solution? thank you!

Thank you very much. I've made it clear by debuging the program, as you said it don't exist before adding item to the listbox. but it still cann't work when I exchange the order of DoModal and AddString method, and I still don't know how to organize the structure. At the same time if I add the instantiation process to the OnInitDialog() function, it seems can break the program logic, what I want is just that I can update the data in the listbox and show it by the dialog, then I can do other work. Do you have any other sugestion? thank you!

ok, I have uptate the question, and I set breakpoints on My "OnInitDialog" function AND My "DoDataExchange" function but it break out before get the breakpionts.
thank you

thank you. but I've add the DoDataExchange method when I create th dialog, and there are the same code as you writen in the first place. but when I instantiate the dialog in class T passing data to it, and it cann't work at the place where add data. And I don't know add what in OnInitDialog method!

Generally I needn't add more code in OnInitDialog method, and other pragram can work well. but this time even I use CreatObject method to create the ListBox, it didn't work.

Hi, but when I don't add the code "a.m_listvalue.addString("Calculative table : "), the dialog can show and there's no problem, but there's no any content in the ListBox.

Thank you.
As you said the 'CWnd' is null, and the instantiated isn't null at stack, but the 'm_listvalue' variable as the element of the dialog is null.I've find it. but don't know how to deal with it.
What can I do?
Thank you!!

Albert Wen-Jie Feng 2-Oct-11 6:46am View

Thank you.
The structure of my program is that the dialog is the output dialog for my data, and the ListBox Control named as m_listvalue is a part of the dialog which is used as showing data. And the data is created or generated in the class T. So I create an object of the dialog in class T, and add data serially into the m_listvalue. when the program carry out to AddString(data), it breaks out. Also I use the MFC to create the dialog class.
How do I deal with the problem?
Thank you!!
