modal dlg

[donbes]

How can I make the edit box text of the main dlgbox = that of the modal dlg. That is, a project contains two dlg boxes, dlg1 and dlg2. One has an edit1 and the other edit2. How can I write code for a button in dlg1 so that the value of edit1 because whtever we have in edit2.
I know how to create the project interface, but I just need that one line of code.

Hi,

Look at

int GetWindowText(
  HWND hWnd,        // handle to window or control
  LPTSTR lpString,  // text buffer
  int nMaxCount     // maximum number of characters to copy
);

WM_GETTEXT

WM_GETTEXTLENGTH

How really depends on exactly what you're trying to do. If you want to update dlg1 when dlg2 is dismissed (OnOK) then:

Create a CString member variable for edit1 in dlg1, say szText1
Create a CString member variable for edit2 in dlg2, say szText2

if (dlg2.DoModal() == IDOK)
{
szText1 = dlg2.szText2;
UpdateData();
}

If you want to update dlg1 as the text changes, i.e. reflect the keys that the user is typing, you'll need to pass a reference to dlg1 to dlg2 and update dlg1.edit1 in response to EN_CHANGE (I believe) notifications from edit 2

szText1 = dlg2.szText2;
does not work. They say 'operator =' function is unavailable

i found the error, instead of CString i had CButton, by mistake.
Thanks
