Can your scanner send any control codes as a prefix to the actual data ?

The scanners I use can send control chars - I use ALT+Something combinations and an access key on a command button to achieve what you want.

If you know the length of the data being scanned you can:
1. Have the scanner first send a control code to fire a command button which enables your textbox
2. Accept the "keystrokes" from the scanner up until the number of chars expected
3. Disable the textbox again (using the Keypress() event to count the chars entered - or using MaxLength and LostFocus)
