• Visual Studio 2008 (Pre-release) Default value of DataMember on client side?

  I create a DataContract like this in a service: [DataContract] public class Person{ public Person(){ _name="leo xue"; } private string _name; [DataMember] public string Name{ get {return _name;} set {_name = value;} } } But when I create an instance of Person class on client side, I find person.Name is a null value. So is there a convient way to pass the default value to client side Hope for your advice. Thank you. svcutil generates partial on type declaration. You can add your own constructor or callback methods with the partial type declaration in another file to prevent overriding by svcutil. zhish [MSFT ...Show All

• Visual Studio 2008 (Pre-release) Nested/Inner Classes and the x:Type Markup Extension

  I posted this on the Usnet discussion, but there seems to be more action here, so reposting... I want to use an TargetType="{x:Type Yadda.Stuff}" where Yadda is a class and Stuff is an inner class of Yadda. Is this possible in Xaml I'd rather not have the namespace polluted with a wrapper class that I'm using to populate a TreeView (as I can't modify the data class itself). Any help is appreciated. Thanks for the quick response. I suppose as a workaround, I could create a sub namespace for these classes ala: namespace App { namespace Window1.Helpers { internal class TreeItemWrapper {} } class Window1 : Window {} } It's not perfect, but it will probably work for me. ...Show All

• Visual Basic error messages microsoft visual basic - hidden modules - help

  Can anyone help me to get rid of the annoying error messages I keep getting when opening & closing XL, publisher, and when shutting down The messages are typicaly advising an error in hidden modules such as 'AutoExec' or 'DistMon'. Other forums I've seen blame Adobe Acrobat for the fault- some sort of add in error, but the Adobe help line say that this is a MS fault. I run a new XP professional operating system, new office 2003 and added a PDF version 7 reader which I've since deleted. I've searched my system for pdf maker *.xla files which some say cause the fault, but I can't find anything by that name. There are no pdf addins on the excel tools menu either.

• .NET Development Step into webservice from ASP.NET project - Typed Dataset parameter

  I have a VS 2005 solution with two ASP.NET web projects. The first one is the front end and the second one has the web services which are getting called from the front end. I have defined a Typed dataset in the webservice project. I have a web method in the webservice project which takes the typed dataset as a parameter. When I debug the front end project and try to step into this webmethod which takes the typed dataset it does not seem to go into the webservice. Rather it steps over the webmethod. However, I have two other webmethods, one that returns a typed dataset and one which takes a string parameter and I am able to step into both of these. Is there something I am doing wrong Thanks ...Show All

• Visual Studio Express Editions VB Express 2005 crashes very often

  I d/l'ed VB express and install went flawless. But it seemed the more I used it the more often it started crashing. No particular event causes a crash more than another. Seems all random. Its to the point now where its really not useable. So I uninstalled, and borrowed a copy of Visual Studio from a friend. Same thing. Random crashes all over the place. Something odd on visual studio though, after I build a sql database and connect it to my program, and have a dataset, if I try to make a query with the query builder, the dataset will disappear. So, I uninstalled Visual Studio and reinstalled VB express 2005. Seems at first it appears better, but soon after crash crash crash. I'm not at that computer right now so I don't hav ...Show All

• Windows Forms Binding controls to nullable fields in strongly type dataset rows

  I have a problem where I cannot leave a data bound control without entering some sort of value. This is driving me up the wall, and I can't believe it isn't a fairly basic need, so here goes... I have the following ... a) 1 strongly typed dataset b) 1 row from a table in the dataset c) 1 BindingSource object d) 1 standard TextBox on my form. I want to bind the "Text" property on the TextBox to the Decimal Salary field on my datarow - the datbase/dataset allows this field to be null. So I tried the following code.... _bindingSource.DataSource = _row; _binding = new Binding ( "Text" , _bindingSource, "Salary" , true ); textBox1.DataBindings.Add(_binding); This works fine ...Show All
