Because NSUndoManager does multiple-level undo, it is not a good idea to implement undo for only a subset of the possible changes to your document. The undo manager relies on being able to reliably take the document back through history with repeated undos. If some changes get skipped, the undo stack state is no longer synchronized with the contents of the document. Depending on your architecture, that can cause problems that range from merely annoying to fatal.

Undo is not always easy to implement, but at least the mechanism for implementing it is straightforward. By default, an NSDocument object has its own NSUndoManager object. The NSUndoManager class enables you to easily construct invocations that do the opposite of a preceding change. The key is to have well-defined primitives for changing your document. Each model object, plus the NSDocument subclass itself, should define the set of primitive methods that can change it.

A single-step undo in item controls is available in the Windows version by pressing Ctrl-Z or Alt-Backspace. Future versions will include multistep undo. You can copy an item, if you want to add to the database another item which is only slightly different. This way you can spare some time by reediting the old item instead of typing the new one all over again.

In Web Mail click Address Book on the left, and then manually delete the addresses you did not want in there. Response to reply for Comment 1780: Operating system is Windows XP Home Edition. This problem is occuring with the sawabush@earthlink.com address. I have other Earthlink addresses associated with other users on the same computer that do not have this problem.

You may undo a move by clicking the Cancel Move button located below your game table. However, please know that if you have clicked on the dice to confirm your move, it is to late to undo the move.

Otherwise known as a mini tummy tuck, partial abdominoplasty is another form of the conventional tummy tuck. The surgery has a smaller cut and the cut around the belly button is not necessary.

When you click the Undo toolbar button or select Undo from the spreadsheet Edit pull-down menu, you will be able to undo most operations such as editing, moving or copying blocks, random fill, recoding or ranking variables, etc. Multi-level undo is supported (with 16 buffers), so you can undo up to 16 of the most recent spreadsheet operations. When you are overwriting an existing data file (while performing the Save As..

A multi-level undo option (available from the Edit pull-down menu) maintains separate queues of previously performed operations for separate objects. The undo operation works on the currently highlighted object; therefore, if you press CTRL+Z, STATISTICA will undo the last operation performed on the currently selected object and not merely the last operation on an object. Note that this option can also be used to undo operations on linked or embedded objects.

Builder Xcessory does not have an immediate UNDO. However, The Revert... option from the Main Window's Edit menu allows you to reload your work from the last saved version of your file or from the last autosaved version of the file. If you have installed extra libraries from ICS, such as ViewKit or EPak, they are installed by default in ${BXHOME}/lib. To use these libraries in your programs just add a link line in "Options->Code Generation Options->Makefile". Then choose "Save As Default".

Undo basically removes the last edit that was made to the selected file. If you cut out a section of audio, for example, that section would be put back in place...just as if the edit has never happened. Be aware that at this time, there isn't "multiple Undo" support in DartPro 32, and you won't be able to recover anything but the last edit made. This feature has already been added to the list of items to implement in the future.

Answer: By default, any action can be undone. Use the undo history dialog for this purpose. In order to prevent accidental (and any other) modifications, you can select the option "Read only" in the program's settings.

You can always use the top drop-down menu’s Undo function to fix errors that you just made (Edit > Undo). If you haven’t saved the draft yet, you can cancel it, which will delete any work you did since you last published but will get rid of any unfixable mistakes. If you already published and your administrator has enabled rollbacks (cached earlier versions), you can roll back to the previous page.

No. FTP does not have a clipboard, wastebasket, or undo feature. Once something is changed or deleted it is permanently changed or deleted. If requested, Telusys can restore data from a backup tape for a fee.

Yes. To undo a note you just inserted, choose Edit-Undo, press Ctrl+Z, or click the right mouse button. The last note you inserted will be removed. You can also undo a delete you just did.

the moment undo/redo is only available for property changes. If you want to undo a property change choose Edit->Undo.

Yes, the usual key on your platform should work: Control-z on Windows and Unix and Command-z on Mac OS X. Also, you can add the shift key into the sequence to get redo. Maybe, but we don't care since it makes playing so much more fun. On some games you can undo all the way back into the previous game!

XmlShell The Ultimate Lightweight XML Editor keeps two Undo information sets: one for the XmlTree (and grid-like views) and the other for the Editor. You might have Undo information for one view, but not for the other. XmlShell The Ultimate Lightweight XML Editor uses the Undo information for the currently focused or working view. Also, switching between the two will cause re-parsing of the XML, which will invalidate the Undo information in most cases.

Monitoring of some environmental indicators take places regularly (for air quality, waste, water and so on). Yes. Training sessions have been organized by the ISO14001 Steering Group in November 1999, August 2000, December 2000 and November 2001. Records can be found on the UNU ISO14001 Online Forum. The training materials are also available on the UNU ISO14001 Online Forum.

Total loss or partial loss of use of a member of the body or inability to earn the same wages in any employment as earned at the time of injury.

A partial denture is composed of replacement teeth attached to gum-colored bases. Designed to fit perfectly into the spaces where teeth are missing, a partial denture affixes to your remaining natural teeth for a seamless appearance. Dr. Wooten may recommend you have crowns on your remaining teeth for a more comfortable fit and natural appearance.

Replacing missing teeth should make eating a more pleasant experience. Start out by eating soft foods that are cut into small pieces. Chew on both sides of the mouth to keep even pressure on the denture. Avoid foods that are extremely sticky or hard. You may want to avoid chewing gum while you adjust to the denture.

The SSE spec differentiates between partial and complete feeds in order to improve communication efficiency. Consider the typical sync conversation between two endpoints: after the initial exchange of feed data between the two endpoints, each endpoint has a complete feed representing the full data set. Successive sync operations between the two endpoints would be more efficient if each endpoint had a way to only send the changed data to the other side. This is the role of partial feeds.

The form allows less than one month to be entered. Validations in December 2005 caused an error for months less than one. The workaround then was to round the time to the nearest 1 and include the details in the budget justification. However, that will be fixed in time for the April 1, 2006 submissions.
