ColumnValue property

Retrieves the value of columns on which an upload or download operation occurred.

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

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

See ColumnCount property.


When an update operation is encountered, the column values given by this property are the values after the update is applied.

Associated column names can be retrieved using the ColumnName property with the same index.

BLOB column values are not available through this property. When a BLOB column is encountered, the ColumnValue is the string "(blob)".


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)))
        ' output 'NULL' for the column value
        MsgBox("Column " + CStr(liX) + ": " + rowData.ColumnName(liX) + _
        ", " + "NULL")
    End If
Next liX

End Sub
