• EileenWin Adding services from an activity

  Is it possible to add a service from an activity . Is there any way to access the runtime I would like to develop an activity so that all the logic is encapsulated in itself (I don't want to ask users to add services in the host). So it would be nice to have an activity that can add the services it needs dynamically (if they were not previouslly added) Any idea Thanks guys for your time. When you say that is not possible to add services after the runtime was started is because doing it can cause some unexpected behavior I mean, I can do the following without any exceptions being throwed, and adding more services to the dataService works. workflowRuntime.StartRuntime(); ExternalDataEx ...Show All

• Jade Skaggs HTMLHelp context popups

  Sorry if this is slightly off-topic, but it is 'Vista UI Development' related. On versions of Windows prior to Vista, HTMLHelp's context popup windows have a 'translucent' drop shadow, albeit that it's achieved by a dot screen. Under Vista (RC1) the drop shadow appears to be opaque and black! To my eyes this is ugly, and out of keeping with Vista's emphasis on translucency, particularly Aero Glass. Are there any flags or settings that can improve the appearance of HTMLHelp popups Failing that might the appearance improve in a future version HTMLHelp is supposed to be the preferred Vista-compatible solution for context help. Richard. FYI: Vista Winhelp RTM delayed until late Febrary ...Show All

• OlderDog Significance of Unlock flag in 'WorkflowPersistenceService' ??

  Hi, I'm currently analysing the use of 'unlock' flag provided in the 'WorkflowPersistenceService' class.As I would like to write a 'Custom' Persistence service. protected override void SaveWorkflowInstanceState(System.Workflow.ComponentModel. Activity rootActivity, bool unlock ) Observations: 1)I always see that unlock is set to true whenever the above method is called to persist an instance. 2)Also the SQL stored proc's provided in the labs handle two cases for 'Unlocked' =0 &'Unlocked'=1...Why is it so 3)As far as my understanding goes this flag means that an instance is being unloaded from the memory and is hence unlocked,so the flag is always set as 'true'....with this assumption why are the procedu ...Show All

• DTHMTLGOD Activity to handle SQL Trigger firing

  Hello, Does anyone have a recommended best practice for how a workflow should "watch for" the event of a SQL (2005) trigger's firing -- rather like the FileWatcher sample Or better, perhaps a code sample Thanks in advance for your thoughts. John Hi, If you want to know about inserts with the SqlDependency you could just monitor a "Select Count(*) From <Table>". This way you get a notification of any insert or delete action. But then the approach using SQL Service Broker would work just fine :-) Maurice Using SQL 2005 you can use the SqlDependency class. The best approach would be to create an external service that use the SqlDepen ...Show All

• Evan Haklar In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0.
