ACQUISITION/PAYMENT PROCESS OVERVIEW 97

10. We want Supplier Name to automatically appear when the user types a Supplier
ID into the Purchase Order Form. Recall from Chapter 4 that this provides us with closed-
loop verification. Therefore, you should format the SupplierName so that the user cannot
change the data that is entered in this field in the same manner as we protected the cus-
tomer fields in the Sales Form in Chapter 4.
11. Right-click on the SupplierName Text Box and select Properties. Click on the
Data tab and scroll down to the Enabled line. Change it to No. Scroll to the Locked line
and change it to Yes. Click on the Other tab and click on Tab Stop and change it to No.

12. Click on the Format tab and click on Back Color. Click on the Build: button
and choose a color that will blend with the style of the form you choose. Click on OK.
Click on Border Style and select Transparent from the pull-down menu. Close the
Properties window.

The subform also needs to be modified. We need to stretch it out to see the entire form.
13. Delete the label on the subform. Click on the subform so that the handles appear.
Drag the left side of the subform to the left side of the main form. Drag the right side of
the subform to the right side of the main form.
14. Scroll to the right of the subform and shrink the size of the InventoryCost Text
Box and Label. Examine the label for InventoryCost. Notice that it is right-justified. Click
on the Align Left to left justify this label.

15. Just as we did not want the users to change the customer's information in the
main portion of the Purchase Order Form, we do not want them to change the
InventoryDescription or the InventoryCost in the subform. Change the properties on
these two fields so that the user cannot enter or change anything.
16. Create a label for the form in the Form Header section entitled Purchase
Order Form.
