Hi Mirek,
the application has no GUI_APP_MAIN.

The application is not multithreaded and runs as follows:

1. It opens a text file, parses it and puts parsed data in a sqlite db;
2. Asks the users (using PromptYesNo that displays correctly) if they want to put the data in the MSSQL db;
3. If the user says yes, then the routine that insert data (the one I posted) is executed.

All the steps above are in the constructor.
