Re: AfxGetMainWnd () call

Hi,
I`ve a CFormView in my SDI application as well as a dialog where the
user can change some settings to specific parts of the software. After
clicking on the "ok"-button I will create another dialog (CWaitDialog)
to verify all these settings the user has made.
I`m not sure if it is recommended to use the constructor to start this
dialog as well as the use of AfxGetMainWnd() (of course in the
mainthread). I`m not really sure in which situations it makes sense to
call such a global method.
CWaitDialog::CWaitDialog (BOOL pFlag, CString& pszCaption, CString&
pszText) : CDialog ()
{
m_pFlag = pFlag;
// Disable the main window and create the dialog.
AfxGetMainWnd ()->EnableWindow (FALSE);
Create (IDD_WAITDIALOG);
// Initialize the dialog caption and the static text control.
SetWindowText ((pszCaption.GetLength()) ? _T("Working") :
pszCaption);
// Display the dialog.
ShowWindow (SW_SHOW);
}
and here is my call of this dialog in the method OnWizardFinish()
which will be called if the user clicks the "ok" button to update his
settings.
void CWizardDialog::OnWizardFinish()
{
BOOL bContinue = TRUE;
BOOL stillWorking = TRUE;
CString dialogtitle ("Please wait...");
CString dialogtext ("Wait for me to do my stuff...");
CWaitDialog dlg (bContinue, dialogtitle, dialogtext);
while (stillWorking && bContinue)
{
//verify all data
//add message to dialog if verifcation failed (to inform t=
he
user)
}
//finished
dlg.Close();
}
best regards

If the while loop is brief then you are flashing up a dialog and then
removing it, which will be annoying to the user. If the while loop is
lengthy it blocks painting and responding to input, which will be
annoying to the user. So the whole concept is kind of clumsy.
Calling Create in the dialog constructor is the normal way to create a
modeless dialog. But disabling the mainframe has the effect of making
the dialog modal. So you have created a modal modeless dialog? And
it disappears all by itself? I think you need to take a few steps
back and consider how best to present whatever you are trying to
present to the user.
