    - Which editor can I use for DataSet property? Hi, I have an custom activity. I want to add a property its type is DataSet to the activity. But I can not bind an instance of DataSet for it at design time. Seems if the type is to inherit from IListSource, like DataSet, DataTable, BindUITypeEditor will draw the UI of property as drop-down list. But it is not I want. I just want to disply the ActivityBind form. How can I change the behavior Regards Carol Tag: Activity to handle SQL Trigger firing

    - how to initialize parameters of a custom activity through XAML file Hi, I have a custom activity which has two dependency properties like this: public static DependencyProperty NameToPrintProperty = DependencyProperty .Register( "NameToPrint" , typeof (System. String ), typeof ( CustomActivity1 )); [ DescriptionAttribute ( "String to be passed to the custom activity1" )] [ DesignerSerializationVisibilityAttribute ( DesignerSerializationVisibility .Visible)] [ BrowsableAttribute ( true )] public string NameToPrint { get { return (( String )( base .GetValue( CustomActivity1 .NameToPrintProperty))); } set { base .SetValue( CustomActivity1 .NameToPrintProperty, value ); } } public static DependencyProperty HashTable1Property = DependencyProperty .Register( "HashTable1" , typeof ( Hashtable ), typeof ( CustomActivity1 )); [ DescriptionAttribute ( "Hashtable to be passed to the custom activity1" )] [ DesignerSerializationVisibilityAttribute ( DesignerSerializationVisibility .Visible)] [ BrowsableAttribute ( true )] public Hashtable HashTable1 { get { return (( Hashtable )( base .GetValue( CustomActivity1 .HashTable1Property))); } set { base .SetValue( CustomActivity1 .HashTable1Property, value ); } } Now I want to initialize these parameters in XAML file. e.g., I want to send "hello world" to NameToPrint property and a new hashtable object to HashTable1 property. Can anybody tell the syntax to achieve this Regards, Chakri. Tag: Activity to handle SQL Trigger firing

    - How to design exception handling? A workflow contains one or more connections to external systems. For example a code activity accesses a database or an erp program. When the external server isn't available an exception will be thrown. How to handle this situation Solution 1: The FaultHandlerActivity suspends the workflow instance. To resume the instance later I've to provide an administrator dialog with all suspended instances (loaded from the tracking store). (Question: will the workflow instance resume with the activity which caused the error ) Solution 2: The code activity handles the exception itself with try..catch and retry repeatedly the access to the external system with increasing time spans like a fax device. What's your opinion to handle this situation Are there any other solutions you recommend Tag: Activity to handle SQL Trigger firing

    - WebServiceInput Activity hi I'm creating a workflow which just waits for a web service to be invoked, but I'm struggling with getting the WebServiceInput activity configured. Currently I have 3 projects, the first one is a workflow project which contains a WebServiceInput activity and the interface class. The second project is the web service wrapper around the workflow project hosting my WebServiceInput activity. I can hit the web service no problem, my web method returns a void. The last (3rd) project is where I'm having problems, I have a single WebServiceInput activity in my workflow, I have referenced the assembly generated from project 1 and configured the activity much the same as in project one. When I go to debug project 3 which is a console app hosting a workflow everything seems to fire up ok, then I hit the web service I was expecting the project 3 workflow to step into my breakpoint on InputRecieved event. It doesn't so I'm confused on how to get this working. Any ideas Craig Tag: Activity to handle SQL Trigger firing

The way that I have the box scrolling right now interupts you typing and sets the focus on the box everytime something is added.

    - Creation of Workflow Tasks inside a Loop Hi Everyone, I am trying to create a Sequential workflow that will dynamically create tasks, that are actually a list of workflow steps that are loaded from a WSS3 list. The workflow I have implemented contains the ForEach action, and inside this I have placed the CreateTask and OnTaskChanged actions (WSS 3), which I configure each time with the appropriate details.

    - Vista API problems.... Hi, I have installed Vista home premium in both the 32 and 64 bit flavours on my development machine. The company I work for produces CAD software for the electronics industry. There are a couple of issues under vista which need immediate attention. Our application is a plain 'C' Win32 MDI SDK application (themed with manifest). I have implemented docking windows and toolbars ala VS .NET 2003 in our application. Firstly: The AnimateWindow API doesn't work correctly under Vista. Under XP and 2000 when the window hides the screen content underneath is kept. Under Vista it becomes corrupted, and you just see the "edge" of the window that has auto-hidden. The windows underneath appear to get no messages whatsoever from the API call, so I have no chance to redraw them. Is this API call completely broken under Vista Secondly: SetScrollnfo on a MDI child under Vista 64 doesn't work for a themed application. When you call it, the scrollbar for the MDI child reverts to a non-themed "display". When you hover the mouse over it, it fades into the themed version but in totally the wrong place. This API call does work correctly under Vista 32, so it's something specific to Vista 64. At present I cannot find any workarounds for either of these problems. I could implement my own version of AnimateWindow which would work as it did under 2000 and XP, but I've got better things to be getting on with. I cannot find a resolution at all to the mdi-child scrollbar issue. It's just very broken. Thanks. Adrian Tag: Activity to handle SQL Trigger firing

    - Compatibility settings not working after uninstall / reinstall Our application launches other executables that require elevated permissions to run. These other executables were sometimes failing to launch the first time the application was run and succeeding after that, and sometimes failing to launch no matter how many times we tried. We implemented a workaround of setting the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\[app path] to ELEVATECREATEPROCESS. This worked great - our programs would now launch correctly and ask for elevated permissions as expected. However, if we uninstall the application and then reinstall it, the workaround no longer works. We are removing the registry key that we created when uninstalling and creating it again when installing. If I run regedit and manually remove and recreate the [app path] key under Layers, it begins working correctly again. Is there something else we need to do at install time to make sure the ELEVATECREATEPROCESS flag is honored for our application Thank you, Jason Tag: Activity to handle SQL Trigger firing

    - Vastly decreased multiuser Jet DB Performance under Vista Testing our VB6-based database application under Vista (Business Pro, Release version, Clean install on fresh partition), all seems largely well with one very noticeable exception: Multiuser Jet 4.0 database access is vastly decreased (often involving several minute waits for simple queries that generally run in one or two seconds); on the other hand, single user access seems quite comparable to its former speed, as does general file system/file server performance.

    - ContentBox size - how to set it, how is it getting set Hi. I am creating a flow document to view in the program and then I save it as an XPS file. This works mostly fine. I use the method on this page to do the conversion to xps. The problem is that the edges of certain fixed size elements (eg. a banner image) are being chopped off in the xps document. The margins of the page are too large - larger than what I told it to be - and the page content is thus obviously correspondingly smaller. So I originally thought it was a margin problem and I put in the wrong numbers. Not so. When I look at the code, I see that the ContentBox is smaller than the PageSize. The content box of course being what the content goes into, so I am guessing that this explains the cropping. This page says that the contentbox is set to the same size as the page by default, but this is not happening here. I don't want to just change stuff to make sure it fits because I don't know if the ContentBox is always going to be this particular size or if something will decide to make it larger or smaller. I can't remember for sure but I think the BleedBox is set to the default as mentioned on the above page - which doesn't help anything but is simply another fact. The content box size - I'm not setting it, I don't know how it is being set and I don't know how to override it. Any ideas from anyone Tag: Activity to handle SQL Trigger firing

    - CoUnmarshalInterface fails with E_ACCESSDENIED across machines in different domains I have an application on XP SP2 that marshals an object into a memory stream via CoMarshalInterface with MSHCTX_DIFFERENTMACHINE (and FWIW MSHLFLAGS_TABLESTRONG) sends the data to a remote Vista machine and waits for a connection. The remote machine receives the data and calls CoUnmarshalInterface. Both sides use CoInitializeSecurity with anonymous authentication levels. Both register standard marshallers via CoRegisterPSClsid and CoRegisterClassObject on the fly. It seems CoUnmarshalInterface reads the OXID from the stream and does a LRPC to resolve it, which fails with ERROR_ACCESS_DENIED. Now what's really odd, is that this request never seems to hit wire. I think I've tweaked everything I can think of (RPC Policy settings, DCOM launch limits, Firewall) All of this work fine on XP SP1 (can't test SP2 right now).

    - Random Vista crashes OK, I'm pissed now. The following is a brief history of my experience with Windows Vista. 1. 6 months ago I set up a dual boot start up on my system between XP Home, and Vista Beta 2. I installed a 2nd. hard drive for Vista, since I didn't want to screw up my system. Beta 2 looked nice, but was very bloated, and a bit unstable. I would get the "Black screen on death" now and then saying I had a USB driver causing the problem. 2. 3 Months ago I installed Windows Vista RC1 over the Beta 2 version. It was more unstable. Actually, it was hardly useable due to the frequent random crashes. For this version, it was just a black screen - then shutdown. It would always happen when either playing a simple game like hearts, or opening a file in Media player. 3. Yesterday, like an idiot, I installed Vista Home Basic over RC1. It is far less bloated, does not take up a lot of space, and therefore, would appear to be more stable. WRONG! Lucky for me I still kept the dual boot system, and have the good old XP to fall back on. Even the Home Basic version, for no apparent reason - Black Screen - Restart! WHY THE HELL IS THIS! I did everything right. My Dell Dimension passed all the pre Vista tests. Does anyone, or everyone, out there have the same issues with Vista If so, what am I missing, other than the fact that I'm a stupid *** trying to get an overpriced operating system to work as good as a Mac!

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

Re: Activity to handle SQL Trigger firing

Dave Britton - VERTIGO

How about using a While activity that looks for some value that the trigger sets in the DB Then you would just need some way to capture your trigger value ...

Dave

Re: Activity to handle SQL Trigger firing

Maurice de Beijer

Using SQL 2005 you can use the SqlDependency class. The best approach would be to create an external service that use the SqlDependency to monitor for database changes and raise an event to the workflow as soon as it has detected one.

Maurice

Re: Activity to handle SQL Trigger firing

Richard Gavel

I've had a similar desire. However, in my case, and I assume anyone elses, SqlDependency is not a good class to monitor inserts because you would not easily know what records got inserted. It's much better for very small tables (like lookup tables) and checking for deletes/updates. My plan is to create service broker event notifications that would contain the necessary information from within a trigger that a custom WF service would listen for and raise workflow events.

Re: Activity to handle SQL Trigger firing

Maurice de Beijer

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

Re: Activity to handle SQL Trigger firing

PricklyPear

Hello, Maurice (and thanks also to all who responded) ...

Testing here indicates that the SQL Dependency approach, hooked into a Windows Service, is viable. I'm also looking at going the SQL Service Broker route. When I have some comparative performance info, and have reasonably packaged the code, I'll post it.

In the meantime, if you have code/thoughts, please let me know.

Thanks again,

John
