• Visual Studio 2008 (Pre-release) Sorting an ObservableCollection<T>

  I was recently using a List<T> to keep track of my data, but we had to move to an ObservableCollection<T> because it will eventually be used in binding to a UI. I was using the List<T>.Sort(IComparer<T>) to sort the list, but it appears that ObservableCollection<T> does not implement this. Is there a way to sort it or do I have to do that manually It seems odd to have to redo this work that clearly is already implemented in .Net but I can't seem to find a way to do it. I figured it was worth asking about. Thanks for the help. You can write your own sorting logic, something like that: public class SortableObservableCollection <T> : ObservableCollection < ...Show All

• Visual Studio Express Editions how to get hardware IDs of system

• Visual Studio Express Editions error connecting to database

  I am using VC# Express and trying to connect to a SQL 2000 database. The error message when I compile the application is as follows: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Is there anyway to connect to SQL 2000 with VC# Express or is this a waste of my time. using System; using System.Data; //ADO.NET namespace using System.Data.SqlClient; //Use SQL Server data provider namespace using System.Collections.Generic; using System.Text; namespace Da ...Show All

• SQL Server 0xC02090F5 DTS_E_DATAREADERSRCUNABLETOPROCESSDATA

  I am moving over 100 tables from mainframe to SQL Server 2005 using SSIS all but 2 tables have worked to some degree. 2 of the packages when executed write 0 rows to SQL Server becaue they are getting this error 0xC02090F5 = DTS_E_DATAREADERSRCUNABLET OPROCESSDATA I have looked at the definitions on the mainframe and SQL Server side all looks good.

Other tools can read the data. Does anyone know what could possibly be wrong ...Show All

• .NET Development why webservice are running on aspnet development server: can we change this

  I have a simple query here: I downloaded a sample webservice from microsoft along with a bat file which creates its virtual library on my IIS.

• Windows Forms DataGridView column filled from lookup table column

  I have two tables Company and Status. Company has a foreign key into Status – Status is the lookup table with two columns: ID and StatusName. I need to build a DGV that will provide a read-only list of what is the Company table, plus the StatusName for each record. All DGV columns are read-only textboxes. The Dataset already holds both tables, but not the relationship between them. The DGV columns are already set up to show records of the Company table but the Status column only shows the numeric foreign key value. Any chance I can do this without a database View or a stored procedure Here’s a bit of code. bindingSource1->DataSource=dataSet1->Tables-> default ...Show All

• Visual C# How can I parse: name="My Value" into a Dictionary? (or other collection object)

  Let's say I have a long string like such: string s = "value=\"Hello World\" value2=\"Hello Goodbye\""; How can I put that into a collection object (eg. dictionary ) so I can access "value" and it would equal "Hello World" (WITHOUT the quotation marks) So... value = Hello World value2 = Hello Goodbye I'd like to access it something like: obj.GetValue("value") and it would return Hello World no worries, in future, its best not to delete the topic (unless its a multiple post) as other users who may have a problem like you had, could find the solution here :-) glad you got it ;-) ...Show All

  I have the following Menu definition. However instead of showing the text of the filenames I'd like to see the actual Images.

• SQL Server Always Fit-To-Page

  All of the reports we have deployed (over 100) are wider than a standard letter sized page. In order to print them correctly, the Fit-To-Page option must be selected in the print dialog. We desperately need a way to make this automatic. I know our users have killed a forest with the paper printed when they forget to select the option. If anyone knows of a way to make the setting of print options like Fit-To-Page automatic or programmatic please respond! Thanks!

• Game Technologies: DirectX, XNA, XACT, etc. Realtime debugging text?

  Hello. All I`d like to do is display crude text somewhere inside the game screen. Can I do this without having to load/use any type of font. The `Print` commands equivelant I suppose It`s just so I can see a variable changing during play. Please excuse this possibly mundane question but I`m fairly new to all this. -Daz. Console.Write() does not add a newline; you need Console.WriteLine() to actually flush a line to the debugger output window. Also note that the text will be sent to the "Output" window in the C# express solution -- not to your game window. If you want to draw text in a game window, then you must use some form of geometry.
