How to write Undo Code in CS3

Andreas,

Do you have an Skype Id i need to talk to you for this concern...

Hi Rizwan,

There is no way I can think of to easily explain or present a recipe for implementing an InvalHandler. Handling undo in CS3 is not trivial, in short there is no way to implement an Undo() as it was known in pre-CS3. Please read the chapter I pointed to in the programming guide. The programming guide is available in the Adobe InDesign CS3 5.0.1 Products SDK/docs/guides/programming-guide.pdf.

Regards,
Andreas

Andreas,

I have checked in the GTTxtEdtNewDeleteStoryObserver.cpp file for InvalHandler, i found it but its I suppose in a different context. I need the flow control in Undo() function of a command say (SomthingCmd.cpp), when Ctrl + Z is done.
So, how exactly i can do that.

Thanks in advance for you kind Support...

Thanks Andreas,

Thank you for the Help. Kindly can you take me through a brief detail of its. I am unable to find it yet in either place...

Hi Rizwan.

To get notified on undo in CS3, you need to implement an InvalHandler. Please see the section Inval Handler on page 132 in the Programming Guide for details. The SDK sample GoToLastTextEdit implements an InvalHandler, which could be interesting to take a look at as well.
