• Software Development for Windows Vista How to serialize xoml only workflows

  I am creating workflows dynamically and serializing them with the XomlMarkupSerializer. My problem is that the x:Class attribute gets serialized. This attribute can not exist when performing xoml only activation. How can I tell the serializer not to write out this attribute I tried not setting the WorkflowMarkupSerializer.XClassProperty but this causes an exception to be thrown when loading the workflow. I assume it can be done by extending the XomlMarkupSerializer however I would prefer not to do this. Any suggestions I figured it out. I was using an example of designer hosting that was compiling the xoml as well as serializing it. When compiling it looked for the XClassProperty and attempted to find the type in an ITypeProvider s ...Show All

• SQL Server Error: The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer

  Hi, I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error: The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer. Then when I try to delete it it gives this other error: Cannot remove the specified item because it was not found in the specified Collection. I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition. Any suggestions why this is ha ...Show All

• Visual Studio Team System PVCS to TFS conversion?

  Hello, we are currently working with the PVCS Version Manager and I want to migrate the data from our PVCS database into TFS because we want to use TFS in the near future. Is there any way to get the data to work in TFS Maybe with a third-party-tool I'm searching since 6 hours now and I can't find anything to do this. Regards Thomas I am evaluating the ComponentSoftware toolsand have found them to not be very robust. I am trying to leverage them in several test scenarios for migrating PVCS (via SVN) and Visual SourceSafe conversions and have had problems every step of the way. Only being able to interact with support via Email has slowed down the evaluation process considerably. Their is not cu ...Show All

How can I launch IE in protected mode from a high integrity process Thanks, Mojo Hi Todd and Sarath,   I don’t need to control navigation, just need to launch. I tried with IELaunchURL.

• Software Development for Windows Vista Problem with InstanceOwnershipDuration

  hello everybody, I have a little problem with understanding the InstanceOwnershipDuration. For testing I have a sequential workflow with 2 Delay Activities; and I added SqlPersistencyService with a TimeSpan of the ownershipDuration for 0 seconds... My sequential workflow looks like: codeActivity => delayActivity for 5 seconds => codeActivity => delayActivity for 10 seconds SqlWorkflowPersistenceService persistence = new SqlWorkflowPersistenceService (connstr, true , new TimeSpan (0,0,0,0), new TimeSpan (0,0,0,2)); workflowRuntime.AddService(persistence); When I start the application, the second codeActivity repeats and never ends like a infinite loop...

• SQL Server Performance problem

  Hi, MyTable : RowNum INT (IDENTITY) PageTitle NVARCHAR(MAX) DomainName VARCHAR(1000) Indexes : Primary key, clustered on RowNum Full Text index on PageTitle , Index on DomainName Data patterns : hundreds or thousands rows per each DomainName value When user performs search, the task is to present 1 entry per DomainName (despite the fact that hundreds of pages on the same site can contain the word). 10 entries per page are presented. Now it is implemented in the following way (using application): 1-st result : SELECT top 1 * FROM MyTable WHERE CONTAINS (PageTitle, '"word"') Let's say, 1st Domain was www.cnn.com 2-nd result : SELECT top 1 * FROM MyTable WHERE CONTAINS (PageTitle, '"word"') AND DamainName NOT IN ('www ...Show All

• .NET Development dotnet 3.0 general question

  I just installed the .net 3.0 sdk on my home computer with visual studio 2005. Does installing the framework have any effect on 2.0 projects Like will i have to say in visual studio what to compile under I'm confused about if there is a compile as 3.0 option, or if everything still compiles as 2.0. Also, if it is 2.0, what do you include to use new language features like var I'm confused about this and i also want to install it at work, but i don't want to mess up any of our projects. What about raw language enhancements then like for instance "var" Do you have to include a using statement or dll for them How does it know to include it ...Show All

• Windows Forms Making a scrollable panel scroll with mousewheel just by hovering mouse

  Hi, I have a particular problem with a possible solution and I am interested in hearing peoples opinions if it is the right way to go about it (or not  ) Some applications I have come across, such as Firefox, will allow the user to scroll the document window just by hovering the mouse over the display area and using the mouse wheel. You don't have to focus / select the display area first. With Firefox, the address bar can have the focus and the keyboard input but you can still scroll the document. Contrasting with IE and Visual Studio, you have to click into the document area before it responds to mouse wheel messages. In my winforms app, I have a tab control with several scrollable tabpages as well as scrollable panels in ...Show All

• Visual Studio 2008 (Pre-release) Support for Group By, Having etc

  How sophisticated are the query capabilities for LINQ. Can a SELECT includes Group Bys, Aggregate Functions, Having Clauses. I have a sophisticated query which runs within the MS Access query designer, but running the same query using .NET OleDb provider results in an error. The query uses joins to selects which have group by and aggregate functions in them. The error message says there is an error in the Syntax after the From clause. So I'm thinking to return result sets back to VB.NET and use LINQ to further process the data into the final result set. The other alternative is use a lot more code to massage the data into the final result set which is going to be nasty. LINQ includes a whole r ...Show All
