I cannot see buffer is initialized by something. Obviously, its going to have junk.

value of buffer is ? and also I think m_text_ctrl(editbox) is null

Could you find problem(buffer) ?

detail
so once i click on the lisitem view it will call/display other window. for that i saved all that tag in the object respectively filename and index of listview. i have taken static int i for object stored. then when i finished each item with corrsponding itemlist for all tags.
when i context switch in the listview from one lits item to other it couldnt display the respective tags for the particular file. is there any missed thing?

In the interest of clean design, the updating dialog shouldn't know anything about the internals of the updated dialog. I recommend posting a command message to the dialog that needs updating, which in turn should handle the message (as a WM_COMMAND) and update itself accordingly.

Here's an easy way:- Add a hidden button to your child dialog.
- Add a handler for the button, which contains code for updating the dialog in the desired manner.
- In the "parent" dialog, post the child dialog a command that simulates clicking the button by doing:
pChildDialog->PostMessage (WM_COMMAND, ID_OF_HIDDEN_BUTTON);

Dear,
will it work in win32 ?

Yes. Use the global ::PostMessage() function.

Dear all..
How can I use GetDC() in a dialog from an MDI CView?
I mean, I have image data in CMyMDIView, and I want to show it in a dialog (CMyDialog).
I've tried this:
CMyDialog *pMyDialog = (CMyDialog*) AfxGetMainWnd();<br />
CDC *pDC = pMyDialog->m_StaticImage.GetDC();
but the second line doesn't work...
I also tried to call the function in CMyDialog that calls CDC from CMyMDIView, like this:
void MyMDIView::OnDraw(CDC* pDC)<br />
{<br />
CMyDialog *pMyDialog = (CMyDialog*) AfxGetMainWnd();<br />
pMyDialog->DoLoadImage();<br />
...<br />
}
where DoLoadImage() contains CDC *pDC = m_StaticImage.GetDC();
but it also doesn't work..
I really bad at these pointer things  ..
Thank you in advance..

CMyDialog *pMyDialog = (CMyDialog*) AfxGetMainWnd();
This won't work because (I assume) your application's window is a mainframe window, not a dialog. Forcing the cast just tells the compiler to assume your main window is indeed a CMyDialog (which is why it compiles), but any attempt to treat the cast object as such will only cause you a lot of pain (because you've made an incorrect assumption about the structure of the dereferenced object).
CDC *pDC = pMyDialog->m_StaticImage.GetDC();
pMyDialog is really a pointer to your application's mainframe window, so trying to reference its m_StaticImage member's DC is going to hurt. A lot.
- You're better off defining a method in your view class that exposes pertinent data required by any class who wishes to display the image. The displaying class (i.e. an instance of
CMyDialog) can be passed a pointer to the view class - or can be so bold as to cast its GetParent() to your view class (assuming the dialog is and will always be only displayed by that view class) - in order to get at the image data, which it can then display in a suitable control.

thank you mr ravi...
I just get your point about referencing from view class. so instead, I just use OnPaint() function in the CMyDialog to call the function to display the image, and it works fine..
thanks a lot...
