Hello all,

I'm trying to use SFPPutFile() and SFPGetFile() to put up some custom 
file dialogs.  I placed in the dialog box two additional radio buttons.
For SFPPutFile(), the Item numbers are 9 and 10, and SFPGetFile(), the
item numbers are 12 and 13 (I think).  Anyways, I created my own
DLOGs in the resource file.  The problem is I can not figure out
how to use the dialog hook function.  Right now, if I put 0L for the dialog
hook function, then I get the dialog on my screen, but I can not access
the buttons.  When I try using a dialog hook function, the debugger gives
me an "odd address" error.  This is how I'm using it:

SaveData()
{
	static Point	dlgOrigin = {DlgLeft, DlgTop};
	SFReply		theReply;
	FInfo		theInfo;
	int		theFile, dummy, ItemType;
	int		ItemNo;
	OSErr		resultCode;
	Rect		DisplayRect;
	ProcPtr		dlgHook;
	int		SaveDataToggle();

	dlgHook = SaveDataToggle;
	SFPPutFile(dlgOrigin, "\pSaveData in which file?", Datafile, 
			dlgHook, &theReply, savedataID, 0L);
	if (theReply.good)
	{
	..... 
	}
	....
}

int SaveDataToggle(ItemNo, Dialog)
	int		ItemNo;
	DialogPtr	Dialog;
{
	.... (stuff to toggle the radio control buttons)
	return(ItemNo);
}

Is this the correct way to use the dialog hook function?

Thanks for any advice!

Maurice
