I wish to have a ComboBox that would contain a list of all the fields that are available in a DataSet. The User would select, from the ComboBox, the field he/she wishes to search. The User would then tab to a TextBox and enter the search criteria. The code would search, the selected field in the DataSet, for the records that "contain" the search criteria and present a list of matching records to the User. The User would then choose a record from the list and select the record to fill a form with the appropriate data.

Any assistance would be appreciated.

1.  Set the RecordSourceType property of the combo box to: Field List
2.  Set the RecordSource property of the combo box to the table or query you want to list the fields for.
3. I generally, include a "Filter" or "Search" button to the right of the "search for" textbox.  In the click event of that button, I generally do something like:

Private Sub cmd_Search_Click

    Dim strFilter as string

    if me.cbo_SearchWhat & "" = "" Then
       msgbox "Select a field to search!"
       me.cbo_SearchWhat.SetFocus
       Exit Sub
    Elseif me.txt_SearchFor & "" = "" Then
       msgbox "Enter a value to search for!"
       me.txt_SearchFor.SetFocus
       Exit Sub
   End If

   strFilter = "[" & me.cbo_SearchWhat & "] LIKE '*" & me.txt_SearchFor & "*'"
   me.filter = strFilter
   me.FilterOn = True

End Sub

Open in new window

I would normally put the combo, textbox, and command button in the form header and have the filter apply to the data displayed in a continuous form below the header.

Text searches don't always work the way you expect them to on numeric fields including dates.  I suggest separate fields for numeric values and dates.  Either you have to know what data type a field is or the user has to know and use the appropriate control.  Then for numbers and dates use =, >, or < rather than LIKE as the relational operator.

Also, using wildcards in front of a text string (LIKE *aard*) will prevent the database engine from using any index.  That means it will do a full table scan.  If your table only has a few rows, you won't notice the performance hit but as it grows it will become slower so make sure you test this feature on a full-size database so you know what to expect.  If you can avoid the starting wildcard (Like aard*), most database engines can make use of indexes (I don't remember which is the case with Jet/ACE, you would have to examine query plans to determine what the engine is doing).
