How do you set value of the that textbox (this.value) to be char?
Explicitly via property value or via controlsource ?
How about setting controlsource to some variable of a prefixed datatype
(char) and then using that variable for seek.
This way u r 100% sure what are you dealing with.

Somehow I always prefered having;

seek cSearchExp

instead of;

seek this.value
