• .NET Development failed to connect to an oracle 8i database

  Hello everybody, I hope someone would be able to help me… I need to programmatically talk to an Oracle 8 database located in a remote server. I have installed the client oracle 8 + Toad into my computers (Windows XP) and I have no problem connecting to this database by using toad. Then I added the System.Data.oracleClient dll to my project, imported it and tried to connect via my application, and had the ORA-12560 error. I can’t open the connection.

• Game Technologies: DirectX, XNA, XACT, etc. texture2d problem...?

  Hi All, i'm new to XNA programming (and directx programming altogether). having a lot of fun with XNA and most things are pretty straight forward for a simpleton like me. here's a problem i'm having that i'm hoping someone can shed some light on. I'm using a lot of photos in my application (a slideshow!). I'm testing with 1 Texture2D and every few seconds loading another image into it using Texture2D.fromFile, etc... Here's what i'm experiencing - if I don't call dispose() on the texture before each new fromfile, it's a memory leak... this makes sense. the problem is that the texture seems to get confused on it's size. I'm using a mix of different sized non-square images. it's like the texture only reads the first texture size called and t ...Show All

• .NET Development parameterized query performance/speed issue

  Hello all, I am running a query on a SQL 2000 table with roughly 50 million phone numbers stored in varchar format. I am converting from an old asp page to asp.net and have run into an interesting issue. The old asp page had a query similar to the following, with varPhone always representing a string variable. "SELECT * FROM dbo.AllNumbers WHERE Phone='" & varPhone & "'" This query ran in under 1 second. When converting to asp.net I decided to take advantage of parameterized queries and used the following: "SELECT * FROM AllNumbers WHERE Phone=@Phone " Using a parameter coded as follows: dbCMD.Parameters.AddWithValue("@Phone", varPhone) This query took 7 seconds to finish. ...Show All

• .NET Development How can I get the AssemblyConfiguration value?

  Hi All, I need to get the AssemblyConfiguration string value which is set in the AssemblyInfo.cs file [assembly: AssemblyConfiguration ( "Retail" )] It seems like all the other attributes in this file can be easily retreived by using the Application class but this one is not for some reason. Does anyone have a code snippet they could share to get this attribute Using C# VS2005 , .Net framework 2.0 Thanks in advance for any help. ~John Quicker and cleaner is to must query directly for the AssemblyConfiguration attribute.

• Visual C# using an Observer Design Pattern with a reference property

  Hi, I was wondering if anyone who has used the Observer Design Pattern with a container of observers knows how to notify when there was a change to a Reference type Property's property. I have searched all over online, but all I can find is when the Property is of a Value Type. For example, check out my "TODO's" in the following code below: class Wheel {    private double _diameter;    private double _width;    public double Diameter    {      get { return _diameter; }      set      {        _diameter = value;               // TO DO: How do I say that ...Show All

• Visual Studio Team System TFS custom control custom ConfigurationSection config file issue

  I developed a custom control for TFS SP1 workitem tracking. Initially it was not using any external databases or config files or anything fancy and it worked great. Once I switched to using business objects for persisting custom workitem data, I ran into an issue of System.Configuration not being able to load "<dll name> assembly or one of its dependencies" when trying to read a custom section within a custom config file. The assembly listed in the exception is the one that contains the definition of the custom ConfigurationSection (works in regular applications), and that assembly and config file are deployed along with the assebly containing the custom control in the same folder. So, the question is: Is there an ...Show All
