Hello, Alexis

By default, V4RB throws exceptions to notify about errors, so it is good practice to handle them.

For example:



  try



    mReport = App.mProject.MakeNewReport(  1, App.mDataSource_SQLite, "SELECT * FROM T1"  )



  catch e as VException

    dim errNumber as Integer = e.ErrorNumber

    dim errString as String = e.Message

    

    // ... do something with this error.

    // e.g. write it into log file or display on some HTML page

  end

For debugging purpose (if you don't want to debug in the Xojo IDE), you can show it in alert,
both a number and a message, so it will be clear what is wrong.
