Simple Dialog Using the Wizard

Objective: demonstrate building a simple dialog using the wizard

Steps:

• Start Visual c++ and build new project with MFC appwizard, SDI called SimpleDialog
• Insert/Resource/Dialog (to open the dialog editor)
• Using the control toolbar, add a static text control and an eidt control
• Editing the static edit box (one way is to right click on control and select properties, another is View/Properties) and change the text to "New Window Title"
• start ClassWizard (View/ClassWizard), it will display a dialog about needing a new class for the dialgo box, click "OK"
• Call the Class name "CGetTitle", then click "OK"
• Class Wizard dialog box should appear, Select "CGetTitle" in the "Class Name" list.
• Select the "Member Variables" tag
• Select the "IDC_EDIT1" ID and then the "Add Variable" button
  This will name a variable to receive the value of the string the user types in using the edit control
• Name the variable "m_newTitle". make sure the category is "Value" and the Variable type is "CString", select OK
• Back in the class wizard, select the Class Name "CSimpleDialogView" and goto the "Message Maps" tab
• In the "Messages" list select the WM_LBUTTONDOWN Message and "Add Function"
• Handler function "OnLButtonDown" should appear in the list of member functions, select it then Select the "Edit Code" button
• Add the following code, so the function looks as follows.

  void CSimpleDialogView::OnLButtonDown(UINT nFlags, CPoint point) 
  {
  	CGetTitle newTitleDlg;
  	if(newTitleDlg.DoModal() == IDOK)
  		GetParent()->SetWindowText(newTitleDlg.m_newTitle);
  }

• Add the following include file at the beginning of the file "SimpleDialogView.cpp" (you should already be there)

  #include "GetTitle.h"

• Build and Execute this program. (click here for an already created project.)
