hello ALL
I have a problem in oracle 10g forms (THIN CLIENT).
I have a form that reads from a card reader (a cheque number) to a text item, the card reader inserts the card number to the field at which the mouse cursor is focusing . the card reader takes 20-30 seconds to finish reading. the problem is i can't know when the card reader has started reading and when it has finished. I want to display a (please wait message) while the card reader is reading. on forms 6i i can use the post-change trigger on the text item to detect that the card reader has finished inserting the card number to the text item. but on 9i and later ... I can't.
please help me,,,,,,,,,,,
thanx

Why can't you use the POST-CHANGE trigger in 9i, if it worked OK in 6i? It exists in 9i too ... What happens? Do you get any error messages?

Why not change the cursor to 'busy'? Please don't use the Post-Change trigger. Use a Post-text-Item instead and set the cursor back to 'normal'.

The cursor is handled by get_application_property and set_application_property(cursor_style).

hello all
thanx again for ur replies.
the problem with the card reader is I cannot control the data flow from the cable to my application in oracle , the card reader inserts the text to any active text item in any active application (also if notepad is running and the cursor is focusing on it , the card reader will insert the text to it).
that's why i can't know when it's reading and where the text will be inserted.
thanx.
