Description

1. JVCLInfo
   

MessageDlg is a replacement for the MessageDlg function in Delphi's Dialog unit. It gives you more control over the appearance of the dialog.
In its simplest form, it does exactly the same as the MessageDlg function in Delphi's Dialogs unit, but has three optional parameters that allow you to choose different default, cancel and/or help buttons.
The second form allows you to provide a different caption of the dialog, but otherwise does the same as the first form.
The third form allows you to provide both a different caption as well as a different image.
If you need more control over button captions and results, use MessageDlgEx instead.
