Well that may work in VB.net but not here. Why would you think it would.
Gambas has an excellent help system, but as I have sais many times 
before, you must read every word, every word and the every word. Try 
reading the help for the TextBox control, in particular the events.


Sheesh! How many times do I have to reply to this same question.












Gambas is NOT Visual Basic
Gambas is not python
nor is it cobol, pascal, smalltalk or a small planet near Beetlegeuse.
















You probably want TextBox.Change.
