• Visual Studio 2008 (Pre-release) Duplex bindings vs Async

  Please excuse my ignorance. I would like to understand what the difference between these two patterns is: 1. use a Duplex contract to do callbacks to the Client 2. Client hosts a service endpoint for callbacks and passes the endpoint address as a parameter to the Server so that it can callback using a service proxy. (2) is possible with none duplex bindings so... What does (1) provide that you don't get from (2) Does the duplex contract do both the service request and the callback in one session context I'm sure there are some subtleties here that I don't see. Thanks, Ting I'd go a touch further. I've done two-way services and they work fine and are wonderful, simply wonderful. :-) However, while you ...Show All

• Visual FoxPro Fonts, ? and set alternate

  Hi; I have lots of older code that uses commands and set alternate to create a text file and then it uses modify command to view the file. I have noticed that on my development PC, this created a file with Fixedsys font. On the installation pcs the font is "Courier". Is there a way to determine what font will be used when issuing commands to a set alte file I know that I can use the font clause in the command itself but I was wondering what determines the default font used. Thank you all for puting up with my "oldie" questions. Aleniko, I don't think the file is created with a font attribute. Maybe you changed your own modify command font ...Show All

• SQL Server SQL 2005 Management tools

  Hi, I installed sql 2005 dev for testing sharepoint, and the management studio was not installed.

I have installed on an other pc the client tools, but i cannot connect to that instance, and i cannot attach the user databases (i get the 5123 error) Can anyone help me how i can install management services without messing up the sharepoint instance Setup doesn't uninstall existing products when you run it multiple times.

• Internet Explorer Development Toolbars (Deskbands) and IE7 Tabs

  Hello, i've developed a toolbar for IE, and it works fine, except IE7 creates for each tab a new toolbar. is there any way of creating only one toolbar that will appear and be functional at all opened tabs i couldn't find anything about it on MSDN... thanks Hi Daniel, The architecture for tabs means that there will be an instance of a toolbar for each tab in IE. This ensures that toolbars do not get confused if they are accessing the contents of the tab and the user switches tabs. Allowing toolbars that are not tied to tabs is under consideration for future versions of IE. Thanks -Dave ...Show All

• SQL Server Question on association models: MINIMUM_ITEMSET_SIZE

  I've been experimenting with the algorithm parameters for a market basket association model. The default MINIMUM_ITEMSET_SIZE is 1. This doesn't seem to make sense: what is the point of a single-member itemset However changing the value to 2 substantially reduces the proportion of good recommendations obtained (which I'm testing via a holdout approach). So I'm obviously misunderstanding what the parameter means. Can someone explain it please, and also explain the observation above)   Every item in a dataset is an "itemset", so there are always "1-itemsets", that's just the list of items and their counts. MINIMUM_ITEMSET_SIZE is really only there for those who are only interes ...Show All

• Windows Forms Binding text box fields to combo box selected value

  I have a small C# windows application with few text boxes and a combo box. I need to bind text fields to the value selected in the combo box, it works fine for the first selection but when I try to select another another item during the same session it gives me an error: "This causes two bindings in the collection to bind to the same property. Parameter name binding" . I think I need to bind the text boxes to may be the selected index change event of the combo box, but I am unable to implement that correctly. private void cmbEmployeeList_SelectedIndexChanged( object sender, EventArgs e) { txtFirstName.DataBindings.Add( "Text" , objDSEmpTrkSys, "EmployeeInformation.FIRSTNAME" ); txtLastNa ...Show All

• Visual Basic NullReferenceException on splash screen

  Here's one for everyone. I have an app that I am using a splash screen with. In Windows XP it works great, no issues. In Windows 2000 not so much. It throws a System.NullReferenceException when the splash screen closes. I can choose continue from the error and the app works fine, but as you can imagin that looks bad to the end user.

• SQL Server NoLock vs ReadPast

  I have been experiencing deadlock errors with two stored procs that I am using. SP1 is a read query that gets all unprocessed orders (status = 0) SP2 is an insert query that inserts new orders (Status = 0) uses a transaction. I have a multithreaded application and once in a while the read query (SP1) will try to read a new row that has just been inserted but not committed yet hence the deadlock arises. If i use a hint "With(NoLocks)" this will be a dirty read and still read the uncommitted insert from SP2 - is this correct Where as if I use hint "With(ReadPast)" this will now only read committed rows and hence the deadlock should not arise - it will not read any uncommitted rows - Correct So I think th ...Show All

• SQL Server SSIS data flow execution monitoring and logging

  Has anyone come up/determined a generic way to capture and log indicative information within a data flow in SSIS - e.g., a number of rows selected from the source, transformed, rejected, loaded, various timestamps around these events, etc. I am trying to avoid having to build a custom solution for each of the packages that I will have (of which there will be dozens). Ideally, I'd like to have some sort of a generic component (such as a custom transformation) that will hide the implementation details and provide a generic interface to the package. It is not too difficult to achieve something similar on the control flow level, but once you get into data flows things get complicated. Any ideas will be greatly appreciated. ...Show All
