CDialog::OnInitDialog
This method is called in response to the WM_INITDIALOG message.
virtual BOOL OnInitDialog( );
Return Value
Specifies whether the application has set the input focus to one of the controls in the dialog box. If OnInitDialog returns nonzero, Windows sets the input focus to the default location, the first control in the dialog box. The application can return 0 only if it has explicitly set the input focus to one of the controls in the dialog box.
Remarks
Windows sends the WM_INITDIALOG message to the dialog box during the Create, CreateIndirect, or DoModal calls, which occur immediately before the dialog box is displayed.
Override this method if you want to perform special processing when the dialog box is initialized. In the overridden version, first call the base class OnInitDialog but ignore its return value. You will typically return TRUE from your overridden method.
Windows calls the OnInitDialog function by using the standard global dialog-box procedure common to all Microsoft Foundation Class Library dialog boxes. It does not call this function through your message map, and therefore you do not need a message map entry for this method.
Observação
You cannot override this method when you use a CFileDialog object in a program that is compiled under Windows Vista. For more information about changes to CFileDialog under Windows Vista see CFileDialog Class.
Example
BOOL CSimpleDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
m_cMyEdit.SetWindowText(_T("My Name")); // Initialize control values
m_cMyList.ShowWindow(SW_HIDE); // Show or hide a control, etc.
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
