SqlTrackingWorkflowInstance Class
Note: This API is now obsolete.
Provides access to tracking data maintained in a SQL database by the SqlTrackingService for a workflow instance.
Namespace: System.Workflow.Runtime.Tracking
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The SqlTrackingWorkflowInstance type exposes the following members.
| Name | Description | |
|---|---|---|
 | ActivityEvents | Gets the list of activity tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| AutoRefresh | Gets or sets a value that specifies whether property data for this SqlTrackingWorkflowInstance should be automatically updated when it is accessed. |
| Initialized | Gets or sets a DateTime that indicates the time at which the first TrackingChannel for this workflow instance was requested by the workflow run-time engine. |
| InvokedWorkflows | Gets a list of SqlTrackingWorkflowInstance objects that correspond to workflows that have been invoked by this workflow. |
| InvokingWorkflowInstanceId | Gets or sets the Guid of the workflow instance that invoked this workflow instance. |
| Status | Gets the status of the workflow instance. |
| UserEvents | Gets the list of user tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| WorkflowDefinition | Gets an Activity that represents the current workflow definition for the workflow instance. |
| WorkflowDefinitionUpdated | Gets a value that indicates whether the workflow has been updated since the last time WorkflowDefinition was loaded. |
| WorkflowEvents | Gets the list of workflow tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| WorkflowInstanceId | The Guid of the workflow instance for which this SqlTrackingWorkflowInstance applies. |
| WorkflowInstanceInternalId | Gets or sets a number that can be used to find related records in separate views for this workflow instance. |
| WorkflowType | Gets and sets the Type of the workflow instance. |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Refresh | Updates the property data for this SqlTrackingWorkflowInstance. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |

SqlTrackingWorkflowInstance objects are returned by a call to both SqlTrackingQuery.TryGetWorkflow and SqlTrackingQuery.GetWorkflows and provide access to the tracking data maintained in a SQL database by the SqlTrackingService for a specific workflow instance. The SqlTrackingWorkflowInstance class optimizes its access to the database for its properties, which maintain collections. For more information, see Refresh.
The following code example shows how to obtain information about all SqlTrackingWorkflowInstance objects contained in a list of displayed workflows. The code creates a ListViewItem for each SqlTrackingWorkflowInstance found in a displayedWorkflows variable. Each ListViewItem contains a string representation of the WorkflowInstanceInternalId, the WorkflowType and Status properties. It then adds the item to a workflowStatusList. The code uses the previously named property values and a string version of the Initialized property to create a new WorkflowStatusInfo object that is also added to the workflowStatusList.
This code example is part of the Workflow Monitor SDK Sample from the Mainform.cs file. For more information, see Workflow Monitor.
// For every workflow instance create a new WorkflowStatusInfo object and store in the workflowStatusList // Also populate the workflow ListView foreach (SqlTrackingWorkflowInstance sqlTrackingWorkflowInstance in displayedWorkflows) { ListViewItem listViewItem = new ListViewItem(new string[] { sqlTrackingWorkflowInstance.WorkflowInstanceInternalId.ToString(), sqlTrackingWorkflowInstance.WorkflowType.ToString(), sqlTrackingWorkflowInstance.Status.ToString()}, -1); listViewWorkflows.Items.Add(listViewItem); workflowStatusList.Add(sqlTrackingWorkflowInstance.WorkflowInstanceInternalId.ToString(), new WorkflowStatusInfo( sqlTrackingWorkflowInstance.WorkflowInstanceInternalId.ToString(), sqlTrackingWorkflowInstance.WorkflowType.ToString(), sqlTrackingWorkflowInstance.Status.ToString(), sqlTrackingWorkflowInstance.Initialized.ToString(), sqlTrackingWorkflowInstance.WorkflowInstanceId, listViewItem)); }
