Question

I have a custom dialog message box that pops-up when a edit control in my main dialog has wrong data.

CDlgError dlgError = new CDlgError(this);
dlgError.Create(CDlgError::IDD, this);
dlgError.m_staticMessage.SetWindowTextA("Error message!");
dlgError.ShowWindow(SW_SHOW);

//more code

I want the rest of the code to be executed only after i press an OK button in my CDlgError pop-up dialog. How can i do that?

Use DoModal instead of Create and ShowWindow to show your error dialog. e.g.

CDlgError dlgError = new CDlgError(this);
dlgError.m_strMessage = "Error message!";
dlgError.DoModal();

As you can see from the code you’ll need to pass in the text and THEN set your message label inside CDlgError::OnInitDialog because the control won’t be initialized before going modal.
