Are you using MFC SDI? [Implicit Creation of a CArchive Object via the Framework^] It will call the <cdocument derived="" class="">::Serialize() you may refer msdn for MFC Serialization.
Otherwise, you need to use APIs for showing up Browse for file dialog and use file APIs to write data.

From CMainFrame to CMainFrame (same source and destination) send a WM_COMMAND message:
SendMessage( WM_COMMAND, ID_FILE_SAVE_AS, 0);

Hi ,,,,
How to disable Menu item in SDI application.
|
|
|
|
|
Add an ON_UPDATE_COMMAND_UI handler and corresponding handler to enable or disable menu items.
Something like...
ON_UPDATE_COMMAND_UI( ID_EDIT_CLEAR, ClearAll ), so ClearAll function should have the following signature...
afx_msg void ClearAll(CCmdUI *pCmdUI);
Call pCmdUI->Enable( FALSE ); to disable menuitem.

and disable menu item. like
pCmdUI->Enable(FALSE);<br />

I have a blog but I won't link it because some people can't take sarcasm. I might hurt someone's feelings! Check the 'email' button on a post of mine if you want the blog address. If you know the blog address and post something back at CP about whatever I post, you are a hypocrite.
