ACC: Fill Record w/Data from Prev. Record Automatically (95/97)

• Microsoft Access versions 7.0, 97

SUMMARY

Moderate: Requires basic macro, coding, and interoperability skills.

When you are creating new records by using a form, you may want to speed the data entry process by having fields in the new record fill automatically with values from the previous record. This article shows you how to create a sample Visual Basic for Applications function called AutoFillNewRecord() that enables you to fill selected fields (or all fields) in a new record with values from the previous record automatically.

NOTE: This article explains a technique demonstrated in the sample files, FrmSampl.exe (for Microsoft Access for Windows 95 version 7.0) and FrmSmp97.exe (for Microsoft Access 97). For information about how to obtain these sample files, please see the following articles in the Microsoft Knowledge Base:

MORE INFORMATION

One technique that you can use to speed repetitive data entry for the field that contains the insertion point is to press CTRL+APOSTROPHE (') to retrieve the value from the previous record.

Another technique is to use the AutoFillNewRecord()function described later in this article. You can call this function from a form's OnCurrent property event procedure to fill all the fields in a new record using data from the previous record. If you want to fill only selected fields, you can create a text box and set the DefaultValue property with a semicolon- delimited list of field names to automatically fill, for example:

Text box:
Name: AutoFillNewRecordFields
Visible: No
DefaultValue: Phone;Company Name;City;State;Zip

1. Open the sample database Northwind.mdb.



2. Create a module and type the following line in the Declarations section if it is not already there:

   Option Explicit




3. Type the following procedure:

   
         Function AutoFillNewRecord(F As Form)
            Dim RS As Recordset, C As Control
            Dim FillFields As String, FillAllFields As Integer
   
            On Error Resume Next
   
            ' Exit if not on the new record.
            If Not F.NewRecord Then Exit Function
   
            ' Goto the last record of the form recordset (to autofill form).
            Set RS = F.RecordsetClone
            RS.MoveLast
   
            ' Exit if you cannot move to the last record (no records).
            If Err <> 0 Then Exit Function
   
            ' Get the list of fields to autofill.
            FillFields = ";" & F![AutoFillNewRecordFields] & ";"
   
           ' If there is no criteria field, then set flag indicating ALL
           ' fields should be autofilled.
           FillAllFields = Err <> 0
   
           F.Painting = False
   
           ' Visit each field on the form.
           For Each C In F
           ' Fill the field if ALL fields are to be filled OR if the
           ' ...ControlSource field can be found in the FillFields list.
              If FillALLFields Or _
              InStr(FillFields, ";" & (C.Name) & ";") > 0 Then
                 C = RS(C.ControlSource)
              End If
           Next
   
           F.Painting = True
   
         End Function 




4. Save the Module as modAuto_Fill_New_Record.



5. Open the Customers form in Design view. Change the form's OnCurrent property to read as follows:
   
   In Microsoft Access 97

   
         =AutoFillNewRecord([Forms]![Customers]) 

   In Microsoft Access 7.0

   
         =AutoFillNewRecord([Form]) 




6. Add a text box to the form, and set the control's properties as follows:

   Name: AutoFillNewRecordFields
   Visible: No
   DefaultValue: CompanyName;ContactName;ContactTitle;Address
