• Software Development for Windows Vista Changing activities Id's

  Hi. I have an application that embedds the workflow. In some point of the application, I let the user change the activity Id through a custom form of mine, but that seems to generate a problem. When the user changes the Id, and then drags another activity of the same type to the workflow, it throws an exception saying that the activity already exists. The code that I write to change the activity ID is quite simple: activity.ID = "someNewID"; //Perhaps I have to do something else after this code... I'm with the Beta 1. Any clues Thanks in advance. I did that and everything was fine. What I'm really t ...Show All

• SQL Server Using Current User Name in Report Builder Filter

  If I create a report in Report Builder that shows some data connected with usernames (e.g. work items assigned to my team members), how can I filter the report data by the current user In Team Queries I do this by specifying @me but it seems it does not work with Reporting Services ... We don't expose the account that RS uses to issue report model queries against SQL Server. What is it that you're trying to achieve Thanks Tudor Trufinescu ...Show All

• Software Development for Windows Vista System image lists and sizes

  Is there a reliable way for an app to determine the size of the icons that Vista is displaying on the desktop I'm not sure if this is a bug or, more probably, an opportunity to learn something new. As a developer of icon software, it's frequently important to know the current size of the desktop icons. There are a couple of ways to check this. I like to get a handle to the system image list (SHGFI_LARGEICON) and then query the imagelist for the size of its images. I'm running under build 5308. Video is set to 32-bit color and 1280x1024 resolution. My method of querying the system image list (large) indicates 32x32 images. The ShellIcon ...Show All

• Software Development for Windows Vista Error adding a custom activity to a workflow

  I defined a new custom (composite) activity as part of a workflow activity library. The library project compiles fine. From within my sequential workflow project, I add this activity to a workflow by dragging it from the toolbox in the designer. I define the required parameters in the workflow that the above activity expects. However I get following error while compiling the workflow project. "error 279: Could not create activity of type 'WorkflowProjectNamespace:WorkflowName'. Could not load type 'ActivityNamespace.ActivityName' from assembly 'ActivityLibraryName, Version 3.0.0.0, Culture=neutral, PublickeyToken=null'. " What gives I have ...Show All

• Visual Basic Creating arrays of controls in VB 2005. Help!

  It seems that the easy and useful capability iof creating arrays of controls which can be indexed is not easy to do in the .NET environment. I ported a small application that had several arrays of textboxes and comboboxes, and checkboxes. The port worked well and did create arrays of  all except the checkboxes. Now I am creating a new application and I want a number of columns of checkboxes. I'd like them to be arrayed so I can use the same index for the control as the data array in the program. Easy right. NO. How do I create arrays of indexed textboxes Have you tried using the tag property in lieu ...Show All

• SQL Server Outer Join Issues in Sql 2005

  Hi, The following query works fine in Sql 2000 database, but it throws an error ('Query contains an outer-join request that is not permitted.') while executing the query on Sql 2005 database.

• Visual Studio Team System HelpText

  I would like to create a filed with helptext longer than 255 characters, 255 is String type limitation, is it possible to create a PlainText filed type and HtmlFieldControl (for instance HelpTab) and put all help info into this filed in Process Template Definition Thanks in advance, Tomasz Yes, 255 is the current limitation for the help text. However, the same restriction applies on default values, so you won't be able to automatically populate that field unless you enter this information manually. I don't think your problem can be solved with the current version. Thanks, Alex ...Show All

• SQL Server Stored Procedures and User Defined Functions

  What are the pros and cons of each One advantage that I can see withh UDFs is that they are a bit a Views with parameters. You can perform joins on UDF columns (which you cannot do with a Stored Proc). You can do the same with Views but UDFs have the advantage that you restrict the number of rows with a parameterised WHERE (or HAVING) clause. A UDF returns table variables, while a SPROC can't return a table variable although it can create a table. Stored procedure is intended to perform a batch of task. UDFs are intended to suppliment the built-in functions to perform simple operation and generate a resu ...Show All

• Visual Studio Express Editions Automatically discover folder path

  Automatically discover folder path. I've searched high, low and sideways on how to get a button click event to automatically search for a particular folder, without having to use the browser dialog method. I'd like to have the program search all hard drives and folder roots to locate and then display the path of a known folder name without the user having to browse themselves. for example I'd like to be able to, at a click of a button, display in a text box the folder path to a folder called Folder1, even though that folder path may be G:\MainFolder\MiddleFolder\LowerFolder\Folder1. All the methods I've found have required either ...Show All

• Visual Basic Visual Basic 2003 Code in Framework 2.0

  I need to upgrade my PCs from the current Framework 1.1 to the new Framework 2.0. Will Visual Basic 2003 code currently running in the Framework 1.1 run in the Framework 2.0 without any recompiling or upgrading Thanks for your help, Marc Yes, you can run different versions of the Framework side-by-side. However, the CLR will attempt to load a different (newer) version of the Framework (if present) when the Framework under which the application was compiled is not installed. So for example, if your app is compiled under 1.1 and the 1.1 Framework is not available then the CLR will look for the pr ...Show All
