• .NET Development Web Services & Partial Encryption

  i am developing a set of web service methods which return reporting data. ideally i do not want to use HTTPS due to the extra performance hit. what would be ideal is to encrypt only that data which is sensitive. for example, 1 particular report has 12 columns of data. but only 1 column of data really needs to be encrypted over the wire (the client name). at the moment my web service method returns a dataset. although i can change this, if it is easier to implement partial encryption by returning a different type. please could anyone advise if it is possible to perform partial encryption in .NET2.0 like this if so i would be grateful for any advice, URLS, etc. to get me off on the right foot. thanks ...Show All

• Visual Studio Express Editions Installing Resources

  I have a .wav file and .exe file in my resources. When I install my program on other computers it won't play the .wav file and it won't open the .exe. How do I make my install so that it installs my resources with it If you have them stored as internal resources then you will have to write them out as a file before using them...the easy solution is to add them to your project as an existing item and set the build action to none and the copy to output directory to copy if newer...this will include the file as an external resource...and then you can reference the files through Application .

• .NET Development sockets vb .net

  Hi! i'm looking for winsock control in vb .NET, but i can't find it. I need an array of sockets.. Is there any way to work like VB6 (Drag & Drop, and calling .DataArrival, .Connect and the other methods and events) I'm newbie in this area.. Thanks! the whole point on having another thread is so it can do a task from blocking the main thread, (UI/application). So if you kept on listening to the port on the same thread, your app would be non responsive. To avoid this problem, you spin up a new thread and keep listening to the port and recieve data and process it, which means your main thread will be responsive now, since work is being done on another thread. ...Show All

• .NET Development How to extract info from tables in http files without too much custom code?

  I am working on Windows form and I am using some publicly accessible http files written by 3 party to extract info from the tables generated by xml and css files that maybe unaccessible for me.

It means that I am using System.Net.WebClient only to read (or download) those files. Can somebody sugest other ways without the direct access to corresponding server controls . ...Show All

• Visual C++ Starting off with C++

• Visual C++ Getting an error RC2188 (Visual Studio 2005, C++)

  Hi, For some reason I'm getting an RC2188 error from the Resource Compiler when accessing the Resource View. There is no documentation for this error. Situation is, I have an RC2 file with my version info in, which is not to be edited by Visual Studio. When the message comes up, it has the path to the RC2 file with a (6) after it. Presumably this is the line number which is #error this file is not editable by Microsoft Visual C++ Anyone have any idea why this is now causing an error (has been working fine in this configuration for months) Thanks in advance Ian.

• Visual C# Partial class inheriting from another partial class?

  Okay, lets suppose I have three pages - customsearch.aspx This is my main ASP.NET page. Lets suppose it has an asp:Literal called 'warningMsg' - searchtemplate.aspx.cs This is a 'base' class which defines some functionality and methods I want in all 'search' pages. It extends the 'Page' class, obviously. - customsearch.aspx.cs This extends the 'SearchTemplate' class, overriding a few selected methods and adding any custom ones I need. So first off, I do all of this using 1.1 style code behind: (only relevant code shown) - searchtemplate.aspx.cs [code] public class SearchTemplate : System.Web.UI.Page { public Literal warningMsg; //other controls here void Page_Load(Object sender, EventArgs e) { warningMsg.Text = "Page Load ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Can one fill a polygon with a transparent color

  Hi all. I'm currently writing a GIS application in which I need to draw Polygons and fill these with a transparent filling so that the user to some extend is able to see the Map beneath the polygon. Is this in any way possible. Thanks Yes, this is perfectly possible - but it's very difficult for me to provide you with much more information as you've not given us much detail to work with Which languages/API's/technologies (e.g. FixedFunc or Programmable) are you using Basically it'll come down to using blending - under D3D9 you'd set the SRCBLEND and DESTBLEND render states and enable alpha blending. You can then provide constant, per-vertex or per-pixel alpha values that can vary the level of transparency. The SDK docume ...Show All
