• Visual Studio Express Editions C# and Sql Server Express Edition, Using Visual C# Express Edition

• Visual C# How to tell if Windows or Web GUI called library

  Is there a system property/method that I can call from within my c# library assembly to tell if it is being called by a windows or asp.net .net program p.s. I have found one way, and that is to put a try catch around a ::global or a webconfiguration call, but I am guessing that this adds overhead. Evan Smith I assume you don't want to clutter up your methods with another parameter (the connectionstring). What you can do then is to make your own repository for the connectionstring inside your DAL. Expose a method for setting the string from the Web or the Windows application. The repository the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Transformation of a single object

  Hi! I just started learning directx and here is the first of probably many newbie questions. Please, be patient :) How can i transform a single object I used Sample Framwork to load a "tiny.x" mesh and created simple triangle.

It's not so tiny after all :) If i move my camera, so i can see the whole mesh and rotate the mesh (or move camera too far away) it disappears. Does it have something to do with my projection parameters Can i scale down this mesh after loading it (so do it only on ...Show All

• Visual FoxPro editbox programmatic change

  I am looking for an easy way to determine if I've made interactive change in an editor box. The issue is that there are about 16 controls on a container, they are initialized from a table record thus their values at activate time generally are not trivial default. I have to save the changes with a SAVE button if I made any but I want this button's click method to quickly determine which control values have been changed. I do not want to do REPLACE for the fields with values that haven't been changed. In case of simple controls like a combobox I can store the initial value in Tag property and do the comparison programmatically. Sometimes t ...Show All

• Visual C# Speed comparison: Filestream.Seek vs. StreamReader

  What's the fastest way to access the contents of 300,000 variable length "records" in an asynchronous manner  A "record" is a text file approximately 20KB long. Here are some possibilities that I've considered: 1. Store each record as a file & store the file path location (ie: C:\test.txt) of the record. Use the StreamReader class (and File location ability of Windows Operating System) to locate, open, and read the file. 2. Combine all records into 1 file & store the record's location in the file (ie: byte 240 of 240000) and record length. Use the Filestream.Seek method to locate the starting file position and ...Show All
