Parent Dialog use text from already disposed of child dialog?

Question

Im currently running a dialog program and within this dialog is creates a child dialog which can accept user input.  Upon user input the child dialog will close and gets disposed of.  In doing this, how can i get this information back to the parent dialog to be able to use it within my program? is a variable for this storage inside the parent the only option i have available?

The normal MFC way is to use member variables of the child dialog
class. That way they're available after the child dialog closes (i.e.
after DoModal returns).

Answer 2

what type of member variable type would u use in this case?

Answer 3

>what type of member variable type would u use in this case?

Whatever is appropriate to the data that the dialog edits maybe?

If you've not already gone through the MFC Scribble tutorial I think
it'd clarify things somewhat for you.

Answer 4

Will suggest you to pick some book on Window Programming and just read it . W.R.T your member variable do you mean public ,private or protected or member variable associated with your control . If you mean access specifier then start with C++ if you mean by Control member variable then just follow David suggestion access you child class member variable with your child class object . That's all you have to do.

Answer 5

You can add a public member function in Parent Dialog class.

For example:

Class ParentDlg
{
private:
    //Declare a variable in which data type you want
     bool IsChildClosed;
public:
   inline void SetChildState()
   {
       IsChildClosed = true;
   }
};
