edit control

[kumar_mk]

I would like to know whether the same Edit Control can handle two types of notification messages, like my requirement is i have an edit control in my dialog box which takes the ID of an voucher, now i have to fill this edit control by two ways 1st> is to manually enter the Voucher ID and press ENTER key (in the keyboard) for the Validation to take place, for this i can handle PreTranslateMessage, VK_RETURN . 2nd> is to scan the Voucher with the Barcode Reader, after scanning, my edit control is populated with the Voucher ID and the validation should happen without entering any Key or doing any action, for this case i can handle ON_EN_CHANGE . my problem is in the 1st case when i enter the 12 digit voucher ID (remember i did not press the ENTER key), the validation is done, since i am also handling the ON_EN_CHANGE message for supporting the 2nd case. how to handle both these cases for the same EDIT control?? thanx in advance kumar_windows

You are putting operations in an edit control that don't belong there. Validation of the VoucherID should be isolated from any edit control. This way you can validate the data when scanned then put it in the edit control.

Handling the ON_EN_CHANGE notification is the way I'd handle this. In the handler function, don't enable the OK button if an invalid voucher has been entered/scanned into the edit control.
