Returns a value from a table corresponding to a match found in the specified column.
DWVLookup( [Value], [Table Name], [Lookup Column], [Result Column Index], [MatchType] )
Value is the value to be found.
Table Name is the table within which the value is to be found.
Lookup Column is the number of the column containing the data to be searched for.
Result Column Index is the number of the column containing the data to be returned.
MatchType defines whether the match has to be exact (False) or the nearest found (True).
|DWVLookup(CarColourComboBoxReturn, Vehicles, 3, 2, FALSE)||The function looks in the Vehicles table for a match, in the third column of the table, to the value returned from the CarColourComboBox.
If a match is found, the function then looks across to the second column and returns the value in the same row as the match found.
The user has also specified that the match needs to be exact (denoted by the FALSE term).
In this case, the Car Color selected in the combo box is "Blue", so the function returns "Golf".
