System_CAPS_noteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

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, seeRefresh.

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, seeWorkflow 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));
}
