Hi, I've done some changes to my pb 9 code. Instead of completing a full build through the project I have built the relevant runtime libraries of the .pbls that have altered. I have then used the .pbds with the relevant exe and dll's that were from the last full build. when I run the exe on a different pc i see values in a dddw which are from my test database in the application. bearing in mind that this dddw is a dddw so it is based on data in the database! the database that the application is using contains different data, yet I still see my test data!! Can anyone help me here?
