STL List

[dotman1]

I have created a STL List customer_list with several detail properties. all works fine. However I now need to store a list of string for each customer. I have added a STL List string_list to the customer object which is accessible the problem is the data in the list is not persisted. Is it possible to have a list within a list? what could be the reason for the list not persisting the data? Regards Mark

Although it is possible to have a list within a list, it would help if you could post some relevant code. You should use the STL vector class instead of a list if you do not do insertions and deletions from the middle of the list.

When you say persist do you mean... a) After setting up string_list the next time you look the data isn't there? b) The thing won't write to a file automatically? c) Something else! Cheers, Ash

If elements in your STL list are more than just a simple type, you can wrap it up into an object, and just have STL list of objects. I used it in a few places in the following article: ProSysLib: Dissecting the Process[^]
