Creating a new Window: m_hWnd not initializing?

esc123 · #1 30-Sep-2009, 11:32

Hello,

I am creating a new window in MFC and have found out that the m_hWnd is not getting initialized. Here is my code:

CPP / C++ / C Code:

void MainDialog::OnBnClickedButton1()

	{
        NewDialog *dlg;
	dlg = new NewDialog( this );
	dlg->Create(IDD_NewDialog);
	dlg->ShowWindow(1);
        }

This goes to a new .cpp where i am calling a SetTimer() function as:

CPP / C++ / C Code:

NewDialog::NewDialog(MainDialog* dlg)

        {
	CDialog(NewDialog::IDD, NULL);
	SetTimer(777, 1, NULL);
        }

Where I get a debug error as:

m_hWnd 0x00000000 {unused=??? } HWND__ *
__________________________________________________ _______________
My overall question is: Why isn't m_hWnd getting initialized? Thanks for any help on this topic.

have you tried

INT_PTR result = dlg->DoModal();

instead of the showwindow
