History

[Marc Bruvry]

I'm sure this has been a past post, so if anyone can point me in the right direction...

I would like to have a history of the last 5 or 10 records so that if interupted, one could go back to the previous record that they were working on...

Thanks,

-Marc

There are different ways to do this, but perhaps the most clever I've seen is in Ray's Retrace Steps demo, which does it using a global variable. Check it out (I think it will work in 8.0)

Are you looking for a scripted button to restore the records?

A simplified version may look like:

Required fields:

TheTable::ModifiedTimestampField

TheTable::ModifiedTimestamp

Freeze Window

Enter Find Mode

Set Field[ TheTable::ModifiedByField; Get( UserName )]

Perform Find

Sort Records[ TheTable::ModifiedTimestampField ]

If[ Get( FoundCount ) > 10

Go to Record[ 11 ]

Omit Multiple Records[ Get( FoundCount ) -10 ]

End If

Hello everyone,

i am a newbie on FM Pro and i ran into this example while i was googling, i was trying to use the Nightwing demo in my db solution to get the BACK button, but i am stuck on some concepts.

How does the example create the history string in the $$StepTrace global variable? How is it updated with every click? I can't find any instruction who does that in the scripts (Retrace or Start)

Can u guys help me figuring that out??

Thanks in advance

Danilo

Edit1: I think it has something to do with the NewLog variable that i can't find where it's defined during the record change

If you examine the layouts, you'll see that a block at the bottom left beside the navigation buttons which says Record xx of yy total. This text is actually being generated in a web viewer object. Look at the custom 'url' in the web viewer and you'll see where $$steptrace gets updated as part of a long 'Let' function definition.

If you don't want to use it this way, then you can replace the HTML at the end of the let function with a null text string, and reduce the webviewer obejct to something very small, a few pixels square. Just put it on all the layouts you want to be able to retrace through and it should work OK
