TvirtualTable260 savetofile question

Post by dpap » Thu 10 Oct 2019 17:37

I use virtualtable to manage some data and save them to a file. Saving/loading file works ok except in one case.
If i delete a field from the table and then save it, when i load it again sows the deleted field (in a DBgrid) without the values.
But i don't want the deleted field at all!
Here is a code snipet i use
// table.Fields[j].free;

What's wrong, please ?

We've tested this behavior using the following code snippet and received the correct results.

Code: Select all

    var Field: TField;
    Field := VirtualTable.Fields[j];
    if Field <> nil then
Please try replicating it in your environment.
