  • ASP.Net Session data lost between pages

    - by Ananth
    Hi, i came across a weird behavior today w/ my web application. When I navigate from a page to another, I lose one particular session variable data. I'm able to launch the app in firefox and able to see that the session data is not lost. I use Response.Redirect(page2, false) to redirect to another page. Below code was used to track session variables System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.txt", true); for (int i = 0; i < Session.Count; i++) { sw.WriteLine(Session.Keys[i] + " " + Session.Contents[i]); } sw.Close(); Can anyone help me in this? Any help is appreciated. ~/Ananth

  • Java sound doesn't work under Linux

    - by Cliff
    Help! I'm getting frustrated by the individual hoops I have to go through to eek sound out of my speakers when running Java apps on Linux platforms! I just installed Fedora 12 and after downloading and running the Java Sound Demo I get exceptions. If I run just a vanilla Java program that plays a wav file it runs silently with no sound and no exceptions. Every other app seems to play sound. I also took some advice from this thread in the Ubuntu forums which almost seemed to work. (Installing aoss got rid of the initial exceptions in the sound demo but I still hear nothing when I play.) can somebody help me figure out what's wrong?

  • jquery validation of controls

    - by Vinodtiru
    Hi , I am looking at validation of some text boxes for somethings like required, minlength, max length, email etc... I am able to get examples that work fine on submit button on page. I want to do this validation on a button click which will only raise a ajax request and not submit of page. On internet all the sample is found was with submit button. Is there a easy way to change this code a little bit o make it work for non submit button click or any new jquery or java plugin to do the same. I am using the jquery.validation.js for now. This works with submit buttons. Any kind of help with suggestion or help is appreciated. Thanks in advance.

  • Entity Framework Performance Problem

    - by Steve Horn
    I'm hoping that someone can help me understand how to overcome a performance problem I'm running into with the latest version of the Entity Framework. In my test, I created my model from a database consisting of around 80 tables. The problem that I'm running into is that the cost of the very first query I run on a thread is very expensive. If I run without pre-compiling views the first query takes anywhere from 5800 to 6600 milliseconds. If I pre-compile the views (see this article) I can get the initial query cost down to about 2800 to 3200 milliseconds. 3 seconds for each request is still unacceptable for my needs. Subsequent queries are very fast. Can you please help me understand how to eliminate the poor performance of the initial query? I'm using the version of entity framework that ships with Visual Studio 2010 RC.

  • AS3: How to access pixel data efficiently?

    - by JonoRR
    I'm working a game. The game requires entities to analyse an image and head towards pixels with specific properties (high red channel, etc.) I've looked into Pixel Bender, but this only seems useful for writing new colors to the image. At the moment, even at a low resolution (200x200) just one entity scanning the image slows to 1-2 Frames/second. I'm embedding the image and instance it as a Bitmap as a child of the stage. The 1-2 FPS situation is using BitmapData.getPixel() (on each pixel) with a distance calculation beforehand. I'm wondering if there's any way I can do this more efficiently... My first thought was some sort of spatial partioning coupled with splitting the image up into many smaller pieces. I also feel like Pixel Bender should be able to help somehow, however I've had little experience with it. Cheers for any help. Jonathan

  • C# ASP.Net The type or namespace name 'Secure' does not exist in the namespace 'source_extranet'

    - by Louis Russell
    Afternoon all, I really need your help as this is a Nightmare! I was earlier having a problem with referencing a 3rd Party Dll (Here) but have overcome this problem and am now having a problem referencing my own classes! Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0234: The type or namespace name 'Secure' does not exist in the namespace 'source_extranet' (are you missing an assembly reference?) The line that the Error points to this line in the class: source_extranet.Secure.BackendCustomData newdata = new source_extranet.Secure.BackendCustomData(); This line of code points to a class in the same folder as the calling code class. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be AMAZING!

  • Can I align the text in a C# balloon tip ?

    - by John
    Hello, I wrote a little C# program that displays text in a balloon tip from time to time. When the text is in English, there's no problem : Everything is aligned to the left and is readable, but sometimes I have some Hebrew text and a left alignment of a RTL language gets all screwy. I was wondering if there's a way to right-align the Hebrew text ? Google pointed me to articles that can help me change the balloon color and font, but none of them have an alignment argument. Is it even possible ? Any help will be appropriated. John
