sql – Open_Workbook Routine Works Manually but not Automatically

Posted by: admin May 14, 2020 Leave a comment


I have the below code pasted into the ThisWorkbook object. However everytime I open the workbook it does nothing, as soon as I go into VBA and manually step through it, it works and the combobox get populated? I’m sure its a setting or something simple rather than anything complicated with the code but I’m all out of ideas as to why this is failing.

Any help would be much appreciated

Option Explicit
Public bClear As Boolean

Private Sub Open_Workbook()

With Application
    .Calculation = xlManual
    .EnableEvents = False
    .ScreenUpdating = False
End With

Dim stSQL As String, rst As ADODB.Recordset, k As Integer, vaData As Variant
Dim objConn As ADODB.Connection
Dim ConnectionString As String
ConnectionString = "Provider=sqloledb.1;data source=SQL-SERVER;Initial catalog=SQL-DB;Integrated Security = SSPI;"
Set objConn = New ADODB.Connection


With objConn
    .CursorLocation = adUseClient
    .Open ConnectionString
    Set rst = .Execute(stSQL)
End With

With rst
    Set .ActiveConnection = Nothing
    k = .Fields.Count
    vaData = .GetRows
End With

Sheets("Menu").CB_Book.List = Application.Transpose(vaData)


Set rst = Nothing
Set objConn = Nothing

bClear = True

With Application
    .Calculation = xlAutomatic
    .EnableEvents = True
    .ScreenUpdating = True
End With

End Sub

Try changing this:

Private Sub Open_Workbook()

To this:

Private Sub Workbook_Open()
