Deleting ghost layer

dNora

 Hi,

I'm trying to delete ghost layers that exists in database but you can't select or view. I can get layers through

foreach(lpp cv~>lpps when(lpp~>purpose=="hv" printf("layer found %s %s\n" lpp~>layerName lpp~>purpose) ) )

dbDeleteObject complains it's invalid type, if I try to use ddDeleteObj then I get

 *Error* ddDeleteObj: argument #1 should be a ddUserType (type template = "b") - db:248248124

What other command can I use?

    Calla,

    The reason why the reply from dNora doesn't help is because your problem has nothing to do with anything discussed in this thread. This topic is about deleting shapes on layers in a layout. Your problem is to do with an error message you get in the CIW - it's not even anything to do with anything being deleted as far as I can see, so I have no idea why you thought it was related to this thread, except for the fact that the error message in the original posting by dNora was referring to an error message due to incorrectly calling the function ddDeleteObj instead of dbDeleteObject. Even then the similarity was simply the message about the expected type of the argument - the operations where completely different.

    I suggest this conversation is continued in your other post and we leave this one alone.

    Andrew.
