Put together in 8 but I'm pretty sure i didn't use anything non FM 7 compatible.

Ignore the new script it doesn't do anything, that was just me forgetting to remove something.

Hey Genx:

Question for you. I've been playing with this since 9 Am. It's after 8 PM my time. Let me try to explain my problem. My app basically does not close windows. I freeze the current window, open a new window and go back by closing the current window. Problem is sometimes I'd like to go back past the last window. Your solution brings you back to the correct layout, but in the wrong window.

I've tried to set the Get(Layoutnumber) to Get(Windowname). No luck. I tried getting fancy with If statements and with variables. No luck. I would appreciate any tips you might suggest.

TIA,

Al

What happens if the originating window is closed?

[aldipalo]

Basically, I don't close any windows. They are all frozen. We work off of a main contacts screen and go off from there depending on what we are trying to do. But we always come back to the main contact screen. The problem is sometimes from contact we go to "Company Filter to see if a company already exists. From there we go to the company screen to see if that's the one we want. We any even look at the jobs that company has given us, blah, blah.

I had a button that just closed all open windows and brought us back to the contact screen, but, people want to be able to back out.

With your solution (Which is quite nice, btw) it just leaves the window open. That's when we will have Toooo many open windows.

[Genx]

Okay, well this should return to the appropriate window and open the window if it doesn't currently exist (i.e. it was closed for some reason).

Thanks a million. I'll look at it right away and let you know if I have any problems.

[Genx]

Actually... i think it may be off a bit, give me a minute.

[Genx]

Nevermind, it was just me testing badly. However, ensure that you track the current layout before you open the new window.

[aldipalo]

I guess we are half way there. It's opening new windows or taking you back in new windows. So I get Contacts - 2, Contacts - 3. What I need it to do is close the current window and return to the previous window.

So:

(Window names) usually denotes the layout as well.

Contacts>Company Filter>CompanyDB>

Contacts>Company Filter>

Contacts>

[Genx]

Righto Try this.

Ok, I think I'm starting to see the problem. In the new scripts we are creating a new window. Don't we want to close the current window and go back to the previous one?

We aren't creating a new window. We are only creating a new window if the window was previously closed.

The back window script does close the current window if its not equivalent to the layout in the next "back step".

I changed the new script: Works fine until we get to Contacts page. If I inadvertently click the back button it requests I select a layout. When I click Ok it closes the Contacts window and switches to my closing script which makes a backup of the DB and closes FM. :)

I'm burned out for today. I really appreciate your help. I'll play more with it over the weekend and let you know how it worked out.

Thanks again for all your help.

... why are you closing 2 windows?

The whole idea is this:

1) If the next "back" entry doesn't have the same window name, close the current window

2) Select the window for the next back entry.

3) If it couldn't find the window and an error was returned open the appropraite window.

Where as you are saying:

1) If the next "back" entry doesn't have the same window name, close the current window

2) Select the window for the next back entry.

3) If it couldn't find the window and an error was returned close the current window for no reason.

Perhaps after 11 hours my brain is fried. I'll look at it tomorrow with a refreshed mind and a night of contemplation. I usually do my best work while I'm sleeping everything works perfectly then.

I'll let you know. Thanks again.

Lol, have a good rest :)
