Advanced: Requires expert coding, interoperability, and multiuser skills.
SYMPTOMS
========
When you use an ActiveX control in a Microsoft Access application, the control
may appear blank when the application is used in the run-time environment. You
may also receive the following error messages
Run-time error '438': Object doesn't support this property or method
-or-
Run-time error '2683': There is no object in this control
-or-
Run-time error '2455': Application-defined or object-defined error
followed by:
Execution of this application has stopped due to a run-time error. The
application can't continue and will be shut down.
Your application then quits. The error you receive depends on both the ActiveX
control and the version of the developer tools that you are using to distribute
the application.
CAUSE
=====
You have pasted a copy of an existing ActiveX control into your form.
RESOLUTION
==========
You can resolve this error by deleting the failing control from the form and
adding a new control from the Insert menu. You should then rename the newly
placed control to the same name as the old control so that any code existing on
the form will work properly.
STATUS
======
Microsoft has confirmed this to be a problem in the Microsoft products that are
listed at the beginning of this article.

Steps to Reproduce Behavior
---------------------------
1. Open Microsoft Access and create a blank database.
2. Import the Customers, Employees, and Orders tables from the Northwind sample
database. The default location for the Northwind database is:
C:\Program Files\Microsoft Office\Office\Samples\Northwind.mdb
3. Create a blank form, insert a Listview control and name it ListV.
4. Type or paste the following code into the form's code module.
Private Sub Form_Load()
Dim clmX As ColumnHeader, mydb As Database, myrs As Recordset
Dim itmX As ListItem
Set mydb = CurrentDb
Set myrs = mydb.OpenRecordset("Customers", dbOpenDynaset)
Set clmX = ListV.ColumnHeaders.Add(, , "Company", ListV.Width / 3)
Set clmX = ListV.ColumnHeaders.Add(, , "Address", ListV.Width / 3)
Set clmX = ListV.ColumnHeaders.Add(, , "Phone", ListV.Width / 3)
ListV.BorderStyle = ccFixedSingle
While Not myrs.EOF
Set itmX = ListV.ListItems.Add(, , CStr(myrs!CompanyName))
If Not IsNull(myrs!Address) Then
itmX.SubItems(1) = CStr(myrs!Address) ' Address field.
End If
If Not IsNull(myrs!Phone) Then
itmX.SubItems(2) = myrs!Phone ' Phone field.
End If
myrs.MoveNext
Wend
ListV.View = lvwReport
End Sub
Private Sub ListV_ColumnClick(ByVal ColumnHeader As Object)
ListV.SortKey = ColumnHeader.Index - 1
ListV.Sorted = True
End Sub
Private Sub ListV_ItemClick(ByVal Item As Object)
Select Case Item.Index
Case Is <= 15
Exit Sub
Case Is >= 15
' Toggle Ghosted property.
Item.Ghosted = Abs(Item.Ghosted) - 1
End Select
End Sub
5. Save the form as ListVForm.
6. Open the form. The list should display without errors.
7. Create a new blank form and copy the ListV control from the previously saved
form.
NOTE: It is important that you copy only the control, not the whole form. Do
not insert the control from the Insert menu.
8. Type or paste the code listed in step 4 into this new form.
9. Save the form as ListVCTlCopy.
10. Open the form. The list should display without errors.
11. Create a new form with a command button to open the ListVForm form and
another command button to open the ListVCtlCopy form.
12. Save this form as MenuForm and in the Startup dialog box make it the Display
Form.
13. Create a distribution disk set using the Setup Wizard and distribute the
application to a clean Windows 95 computer. Make sure to include the ActiveX
control file (.ocx) in the list of distribution files.
When you run this application on the clean computer, the ListVForm form will work
without any errors, but the ListVCtlCopy form will produce the errors described
in the "Symptoms" section of this article.
