:sign0161:

I attached my app

Now I can't copy or paste or do anything in the b4p app. I get this error message:

Protected memory read or write was attempted. This often indicates that other areas of the memory is damaged.

I opened and ran your program. It works fine.

When do you get the error?

Usually when I select the first file very fast and click on cancel the two input box and the dir chooser. After this I run again and select the csv file again so fast, now my app crash at this time.

No crash here. You can try running the compiled application and see if it happens.
