In order to do that you'd have to know what it is (which is possible). If you know what it is, why not just default it into the combo and not make/let them select anything?
Why indeed have a combo box? Just have a text box with the user name.
If you must have a combo, set Locked to Yes and set its value to the user name when the form is opened, or alternatively set the combo's row source to the user name.
You guys are right no need for a combo box just a text box with that users name defaulted based on the windows login. So how do I achieve this? I got the User log in name from my IT / Network guy and added to my employee's table under EmpUserLogin..
EmployeeId / EmpUserlogin / Last Name/ First Name/ Full Name
So now on my form how I do I get the textbox to display the name of the person logged in on the computer??
