As you can see, I already have a logging code. My event is called every time something read a calculated field. So at the start of the program, when the dbgrid reads whatever it displays, and when I scroll it later, then for only those records.
And I know, that I shouldn't do this, but I'm handling recursive calls, and I'm returning the cursor where it was, so I should be able to do this.
And now the case is that this table has a "foregin key" that points into the same table, so I have to access those records, and I have to make calculated fields from them. To be worse, I have to show the effect when the user changes one value instantly, so this is why I use calculated fields.
Anybody that knows how to fix this, or can link here some webpage about this topic would be appreciated. Thanks!
