Save As Common Dialog Box

1. The Save As common dialog box provides the user a mechanism for specifying the name of a file to save. We�ll worry about how to save a file in Class 6. The box is displayed by using the ShowSave method. Here�s an example of a Save As common dialog box:
   
   
   
   
   
   
2. Save As Dialog Box Properties (mostly the same as those for the Open box):
   
   

   CancelError	If True, generates an error if the Cancel button is clicked. Allows you to use error-handling procedures to recognize that Cancel was clicked.
   DefaultExt	Sets the default extension of a file name if a file is listed without an extension.
   DialogTitle	The string appearing in the title bar of the dialog box. Default is Save As. In the example, the DialogTitle is Save As Example.
   FileName	Sets the initial file name that appears in the File name box. After the dialog box is closed, this property can be read to determine the name of the selected file.
   Filter	Used to restrict the filenames that appear in the file list box.
   FilterIndex	Indicates which filter component is default.
   Flags	Values that control special features of the dialog box (see Appendix II).

   
   
3. The Save File box is commonly configured in one of two ways. If a file is being saved for the first time, the Save As configuration, with some default name in the FileName property, is used. In the Save configuration, we assume a file has been previously opened with some name. Hence, when saving the file again, that same name should appear in the FileName property. You�ve seen both configuration types before.
   
   
4. When the user closes the Save File box, you should check the returned file name to make sure it meets the specifications your application requires before you try to save the file. Be especially aware of whether the user changed the file extension to something your application does not allow.
