Examples

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));

Remarks

Note

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, see Refresh.

Properties

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 or sets the Type of the workflow instance.
