Syntax

expression .GetMatchingRowsForRefreshConflict(ShapeInConflict)

expression An expression that returns a DataRecordset object.

Parameters

Name	Required/Optional	Data Type	Description
ShapeInConflict	Required	Shape	A shape linked to data that has a conflict after the data recordset is refreshed.

Return Value

Long()

Remarks

The GetAllRefreshConflicts method returns an array of shapes where a conflict exists between data in the shape and data in the data-recordset row to which the shape is linked. To determine which data-recordset rows produced a conflict, you can then pass each of these shapes in turn to the GetMatchingRowsForRefreshConflict method, which returns an array of rows that are in conflict for a given shape.

Rows in the data recordset can be in conflict when two or more of them have identical primary keys, and may link to the same shape. When this occurs, GetMatchingRowsForRefreshConflict returns an array containing at least two row IDs.

Conflicts can also occur when a previously data-linked row from the data recordset is removed. When this occurs, the method returns an empty array.

To remove a conflict, pass the shape that has the conflict to the RemoveRefreshConflict method, which removes the conflicting information from the current document. Information about conflicts is persisted in the current document until either you delete the shape in conflict or you call RemoveRefreshConflict on the shape.

Example

This Microsoft Visual Basic for Applications (VBA) macro shows how to use the GetAllRefreshConflicts method to determine which shapes, if any, have conflicts after a data recordset is refreshed and then use the GetMatchingRowsForRefreshConflict method to determine which data recordset row or rows is causing the conflict. It refreshes the data recordset most recently added and if it finds no resulting conflicts, prints "No conflicts" in the Immediate window. If it does find conflicts, it passes each of the shapes that have conflicts to the GetMatchingRowsForRefreshConflict method and prints the resulting row IDs in the same window.

Before running this macro, make sure that the most recently added data recordset is a connected (non-XML-based) data recordset and that the connection to the original data source is still available. Then delete a row in the data source or make another change that will cause a conflict when you refresh the data recordset.
