MFC, modeless dialog not showing

modeless dialog not showing

Author	Message
Michael Fo #1 / 4	modeless dialog not showing I have a modeless dialog that I am trying to show from another dialog. For some reason the dialog will not show on creation. Oddly enough, I have another modeless dialog that does work and I don't see any differences. Is there something that I am missing? Any help would be appreciated. Michael Fox //Host code from the dialog that instantiates the modeless dialog if(m_pDlg->GetSafeHwnd() == 0) { m_pDlg->Create(); Quote: } else { m_pDlg->PostMessage(WM_DLG_FRONT); Quote: } //Create function from the modelss dialog BOOL CProcessBlobDlg::Create() { BOOL bRetValue = CDialog::Create(CProcessBlobDlg::IDD); return bRetValue; Quote: }

Regards, Ruben.

Bjarne Nielse #3 / 4	modeless dialog not showing I like this better if (::IsWindow(m_pDlg->m_hWnd)) m_pDlg->PostMessage(WM_DLG_FRONT); else m_pDlg->Create(); After BOOL bRetValue = CDialog::Create(CProcessBlobDlg::IDD); shouldn't you call if (bRetValue) ShowWindow(SW_SHOW); ?? -- Bjarne Nielsen Quote: > I have a modeless dialog that I am trying to show from another dialog.

Todd Brook #4 / 4	modeless dialog not showing Sorry for such a question, but where is WM_DLG_FRONT declared and what is it declared as? todd <snip> Quote: > m_pDlg->PostMessage(WM_DLG_FRONT);
