Use the dialog box as a subwindow

 

Using a dialog box as a subwindow is a very common technique, which simplifies the interface design and makes it easier to modify.

Simply put, the key to this technology is to create a modeless dialog box and specifyChild style and borderless style,.

Next, useCDialog and message ing. Use the following code to create a subwindow:

Int CMy59_s1View: OnCreate (maid)
  

{
  

If (CView: OnCreate (lpCreateStruct) =-1)
  

Return-1;
  

// Create a subwindow
  

M_dlgChild.Create (IDD_CHILD_DLG, this );
  

// Locate again
  

M_dlgChild.MoveWindow (0, 0, 400,200 );
  

// Display window
  

M_dlgChild.ShowWindow (SW_SHOW );
  

Return 0;
  

}
  

In addition, a similar technology is used.The CFormView derived class is used as a subwindow. When editing dialog box resources, you must specify the Child style and borderless style. Then, use ClassWizard to generate a derived class based on the CFormView class. However, since the member functions of this class are protected, you need to modify the generated header file as follows:

Class CTestForm: public CFormView
  

{
  

// Change the constructor and destructor to a common function.
  

Public:
  

CTestForm ();
  

Virtual ~ CTestForm ();
  

DECLARE_DYNCREATE (CTestForm)
