• .NET Development VERY slow binary serialization of strings coming from SQL

  Please help! This is probably the weirdest issue I've ever encountered. I'm trying, in C#, to binary serialize an array of strings that come from a SQL Server 2000 database.  Problem is, this takes orders of magnitude longer than if the strings don't come from the database. The EXACT same 35000-length array of strings takes 0.1 seconds to serialize if the strings don't come from the database, and 40(!) seconds to serialize if they do. So for instance: ...     SqlConnection conn = new SqlConnection("...");     //In my database, this will return 34769 rows     SqlCommand comm = new SqlComm ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. using Microsoft.Samples.DirectX.UtilityToolkit

  I just started working again on a game I had been writing and abandoned for quite a while. I have managed to get it working with the latest release of the SDK but now I have run into a problem trying to add a new UI. Im am trying to add some of the the controls from the customUI tutorial that came with the SDK . I added "using Microsoft.Samples.DirectX.UtilityToolkit;" to my code but of course the compiler didn't reconize Microsoft.Samples... After some googling I realized I had to include the files from "Microsoft DirectX 9.0 SDK (October 2005)\Samples\Managed\Common" in my project. the problem is when I do this and try to compile I ge ...Show All

• Visual C++ C++/CLI String Arrays

  Hi, I am trying to learn the C++/CLI syntax. Right now I am wondering about the proper way to declare an array of String. I am using this, array<String^>^ testArray; Is that the correct way Also, is there any C++/CLI examples, somewhere I know the general scenario is that there are more VB, C# software engineers around, supposedly.

• Visual C# Cannot implicitly convert type 'int' to 'bool'

  Hello everyone, I am a complete novice so sorry if I've broken any etiquette rules and for asking such a basic question. Basically I want to return the index of a string I'm searching for. I then use .replace() to apply some rules depending on whether it is at the beginning of the word or in the middle. If it doesn't appear then I leave the text as is. Everything is ok if it appears in the word or not at all but I thought that if the string would appear at the beginning then the index would be 0 So I check else if (intLocation = 0) { GeneratedText = GeneratedText.Replace( "γχ" , "g" ); } Sourc ...Show All
