Syntax

Public Property ColumnName(ByVal index As Integer) As Object
Member of DbmlsyncCOM.IRowTransferData

Parameters

index   A zero based integer specifying the column name to be retrieved. Index values range from zero to one less than the ColumnCount property value.

Example

The following Visual Basic .NET example iterates through all the columns for a row in the UploadRow event. It determines if a column value is null and outputs column names and values.

See UploadRow event.

Private Sub dbmlsync1_UploadRow(
 ByVal rowData As DbmlsyncCOM.IRowTransferData
)
Handles dbmlsync1.UploadRow

Dim liX As Integer
For liX = 0 To rowData.ColumnCount - 1
    If VarType(rowData.ColumnValue(liX)) <> VariantType.Null Then
        ' output the non-null column value
        MsgBox("Column " + CStr(liX) + ": " + rowData.ColumnName(liX) + _
        ", " + CStr(rowData.ColumnValue(liX)))
    Else
        ' output 'NULL' for the column value
        MsgBox("Column " + CStr(liX) + ": " + rowData.ColumnName(liX) + _
        ", " + "NULL")
    End If
Next liX

End Sub
