From: Stephen J. Herschkorn on 16 Aug 2005 13:28 Here is another benefit of doing sudokus on an Excel spreadsheet. The Edit/Undo command keeps a buffer of significant length, so if you find you made a mistake, you can undo the last ten or so changes. -- Stephen J. Herschkorn sjherschko(a)netscape.net

The default is 16, and if you'e happy with that then well and good. If you want more, then (from Micro$oft article 211922) 1. Close any programs that are running. 2. On the Start menu, click Run. Type regedit and click OK. 3. In the Registry Editor, expand the following key: HKey_CURRENT_USER\Software\Microsoft\Office\9.0\Excel\Options 4. On the Edit menu, point to New and click DWORD Value. With New Value #1 selected, type UndoHistory, and then press ENTER. 5. On the Edit menu, click Modify. In the Edit DWORD Value dialog box, click Decimal under Base. Type a value between 0 and 100 for Value. Click OK and quit the Registry Editor. 6. Start Microsoft Excel. Microsoft Excel stores an undo history for the number of actions you specify in step 5. Setting it high and then making numerous sweeping changes to large worksheets will of course stress your system's RAM, but setting it to 100 for sudoku shouldn't be any problem at all. -- Patrick Hamlyn posting from Perth, Western Australia Windsurfing capital of the Southern Hemisphere Moderator: polyforms group (polyforms-subscribe(a)egroups.com) |
