Re: Open Dialog window in MFC

When you double click on the button as I showed previously the VC++ 6.0 IDE will create the correct message map entry for you -- you do NOT have to code that yourself. After clicking that button, the message map in the *.cpp file should like something like this:

(Toggle Plain Text)

BEGIN_MESSAGE_MAP(CDlgtestDlg, CDialog)
	//{{AFX_MSG_MAP(CDlgtestDlg)
	ON_WM_SYSCOMMAND()
	ON_WM_PAINT()
	ON_WM_QUERYDRAGICON()
	ON_BN_CLICKED(IDC_BUTTON1, OnButton1)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

And in the *.h file

(Toggle Plain Text)

protected:
	HICON m_hIcon;

	// Generated message map functions
	//{{AFX_MSG(CDlgtestDlg)
	virtual BOOL OnInitDialog();
	afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
	afx_msg void OnPaint();
	afx_msg HCURSOR OnQueryDragIcon();
	afx_msg void OnButton1();
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
}

Attached is the complete project I made, minus compiler-generated files.

Re: Open Dialog window in MFC

Your OnSim should look like:

C++ Syntax (Toggle Plain Text)
void YourFirstDialog::OnSim()
{
  CSimConFig dlg;
  dlg.DoModal();
}
void YourFirstDialog::OnSim()
{
  CSimConFig dlg;
  dlg.DoModal();
}

Please reread the manual concerning the return values of DoModal(). There is no point in comparing the return value against control IDs.
Another strange thing: are you sure the Button is in CMainFrame? Usually you only have IDs of menu items with ON_COMMAND handlers there.

>>Are you sure the Button is in CMainFrame?

Dialog projects do not have a CMainFrame class (assuming he created a dialog project, not SDI or MDI)

Re: Open Dialog window in MFC

Hey AncientDragon and Jencas,

thanks a million for all your help. From looking at your example AncientDragon I think I may finally understand what is going on. Again thank you for posting that. Could I ask one small favour from you guys, could you recommand a good book for MFC, I have "Introduction to MFC Programming with Visual C++" by Richard M. Jones and "Professional MFC with Visual C++ 6" by Mike Blaszczak but im finding it hard to dig what I want from these two books. Is there any "bible" book for MFC like "Programming principles and practice using C++" by Bjarne Stroustrup book is for C++? Thanks again for all your help and time.

Colm.

Re: Open Dialog window in MFC

There have been many major changes to MFC since that compiler was released. I started learning it by doing the Scribble Tutorial

That tutorial will not be useful on VC++ 2005/8 compilers.
