Parameters

approvedStates
Type: Microsoft.UpdateServices.Administration.ApprovedStates

Include updates that match the specified approved state. You can specify one or more states. For example, specify LatestRevisionApproved to include only the updates with the latest revision that are approved.

fromArrivalDate
Type: System.DateTime

Start date and time to search for updates. Updates synchronized on or after this date and time are included in the collection. To avoid filtering updates based on a start date, specify DateTime.MinValue. You must specify the date in Coordinated Universal Time.

toArrivalDate
Type: System.DateTime

End date and time that is used to search for updates. Updates synchronized on or before this date and time are included in the collection. To avoid filtering updates based on an end date, specify DateTime.MaxValue. You must specify the date in Coordinated Universal Time.

updateCategories
Type: Microsoft.UpdateServices.Administration.UpdateCategoryCollection

An UpdateCategoryCollection of categories that contains the product categories for which you want to get updates, for example, the Windows family. This parameter can be null.

updateClassifications
Type: Microsoft.UpdateServices.Administration.UpdateClassificationCollection

An UpdateClassificationCollection collection that contains the classification of updates for which you want to get updates. For example, Critical Updates. This parameter can be null.

Return Value

Type: Microsoft.UpdateServices.Administration.UpdateCollection

An UpdateCollection collection of the most recent revision of any update that matches the given criteria.

Exceptions

Exception

Condition

ArgumentOutOfRangeException

fromSyncDate cannot be greater than toSyncDate.

Remarks

updateCategories and updateClassifications can both be null, in which case the return will not be filtered by categories or update classifications or both.

This search method will search on and return only the most recent revision of any update. For example, if an update was added on Monday and revised on Tuesday, and toSyncDate includes Monday but not Tuesday, the update would not be returned. To get all updates, call GetUpdates.

Examples

The following example shows how to get a collection of updates that represent the latest approved revision for any time, any category, and any update classification.

Dim updateCollection As UpdateCollection
updateCollection = updateServer.GetUpdates(ApprovedStates.LatestRevisionApproved, Date.MinValue, Date.MaxValue, Nothing, Nothing)
