Reading data from a table (newbie MS Access)

I realize the newbieness of this question, but google searches are not helping me.

I've created an MS Access database and am trying to automatically update a cell in a row when another cell is updated with data f开发者_JAVA百科rom a drop-down menu. I've created a sub "afterupdate" for the text box in the form, and can simply create a "select case" to update the cell based on what value is entered.

However, the Select Case would be very long, and I already have the list of values populated in another table in the database. Is there a way to set the value of the new cell to whatever the corresponding value is?

Example:

Table 1:

Mode --- Time

A --------- 1:00

B --------- 2:00

C --------- 4:00

So, in my form, when I select "A" for one cell, another cell would automatically update with the information "1:00". Again, "Select Case" works, I am wondering if there is a faster way.

If you wish to do this in a form, lets try

• Create a form with a combo box called cmbMode.
• On the Properties/Data change Row Source to SELECT * FROM tblModes.
• On the Properties/Format change Column Count to 2.
• On the Propeties/Format change Column Widths to 3,0
• Create a Text box called txtTime.
• On the Properties/Data change Control Source to =[cmbMode].[Column] (1).

That should auto update on change.

EDIT

Just as an after thought, this will not update values to a table, as the text box will not be bound to a field.

You could change the combo box AFTER_UPDATE event to use (if the textbox is bound to the TIME field) to use

Time.Value = cmbMode.Column(1)
