Retrieves the column names for a row on which an upload or download operation occurred.
Public Property ColumnName(ByVal index As Integer) As Object Member of DbmlsyncCOM.IRowTransferData
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.
See ColumnCount property.
Associated column values can be retrieved using the ColumnValue property with the same index.
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 |
