How do I delete objects in Lookout 4.5.1

[Rexkarz]

What are the proper steps to delete objects in Lookout ? The Help files make no mention of how to do this.

remove all connections to the object, as well as display items.
Select item in Object Explorer, press Delete

How do I remove connections to an object ?

[Mike@DTSI]

Use the Connection Browser, in the Object menu,  to find connections to an object

How do you delete the connections ? I think I can find them, but deleting is another story.

For example, we have a Pot1, and the connection Pot1.value = Pot2.value.

To delete Pot1, we need to delete the connection first. In Object Explorer, right click on the Pot1, select Edit Connections.... You will see the connected datamember in "Existing connections". Here we see "value". Double click on "value", in the yellow field, there is the connection. Click "Clear", or you manually remove it, then click "Accept". Then the "value" will disappear in "Existing connections", which means the connection is removed. Without any connection, we can delete the Pot1 now.

I tried that, deleted one connection and the program crashed. Upon re-opening, all my trend screens are now blank. Is my data all lost forever? I have worked on 3 systems that have lookout and this has happened on every one of them. I am very unhappy with this program. We are considering trashing this system and going to Wonderware. I am sick and tired of losing my customers' data trying to use this program. The lack of support is incredible.

Well, I managed to restore most of the database and will weigh the options as to whether I re-write the SCADA or continue trying to delete items one by one. It seems impossible to delete something with more than one connection. Also, I get "expression cannot be empty" which is a bear....

Maybe you don't double-click on the connection to select it. In "Existing connections", you need to double-click on a connection, and then click "Clear" and "Accept". Then you need to double-click the next connection. If you just click on other connection, it's not selected.

For example, see attached pic 1, I have two connections Panel1.height and Panel1.activate. I select "height" and clear it. See pic 2, height is deleted. But if I click on "activate", it is not selected. The connection is still "Panel1.height". Then if I "Accept", it will try to create a new connection because the connection to Panel1.height doesn't exist. WIth the empty parameter, it will return the "expression cannot be empty" error.

So you need to double-click on "activate" to select it and clear it.

Have a try.

Thank You, Ryan. Sorry for my venting here, probably not the best place to do so, but I can't edit it. LOL (feel free to edit)

OK, I am going back to the jobsite tomorrow to bang my head against the monitor some more. I am looking at the pics tonight and will be adding my own soon.
