Weird behavior

  
I've made this "Minify" class that inherits from MemoryStream and I want to use it to minimise the amount of whitespace in for example css and javascript files. To begin with I'm not doing anything complex just a simple replace.using System;using System.Collections.Generic;using System.Linq;using System.IO;using System.Text;using System.Web;using System.Text.RegularExpressions;namespace Output{    public class Minify : MemoryStream    {        private Stream stream = null;        public Minify(Stream stream)        {            this.stream = stream;        }        public override void Write(byte[] buffer, int offset, int count)        {            string content = UTF8Encoding.UTF8.GetString(buffer);            content = LimitWhitespace(content);            stream.Write(UTF8Encoding.UTF8.GetBytes(content), offset, UTF8Encoding.UTF8.GetByteCount(content));        } &nbs

weird Rating Control behavior

  
Hi folks! :)I have Rating control on my page. The page is a subpage of nested master page. On that page is updatepanel and wizard with TemplatedWizardStep inside it and inside TemplatedWizardStep is Rating Control.Master.Page -> NestedMaster.Page -> Content.PageI allso have googlemap inside that wizard(on different step) so i need to register google initialize() for it to work.So by registering googlemap like example below Rating Control freezes. Private Sub ScriptManager1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles ScriptManager1.Load ScriptManager.RegisterStartupScript(Page, Page.GetType(), "onload", "initialize()", True) End Sub But if i include script tags in string like example below, Rating Control does not freeze. Private Sub ScriptManager1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles ScriptManager1.Load ScriptManager.RegisterStartupScript(Page, Page.GetType(), "onload", "<script>initialize()</script>", False) End Sub Everythnig works, but i wonder, WHY :) Why is Rating Control freezing in sample1?

Weird Exception: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizon

  
Hi guys I have an XBAP application that uses a Xamdatagrid from Infragistics. I have some filtering on this grid, that rebinds after a filter. The problem is, when a user has scrolled to a certain point and then filters, the rebinding causes the grid to scroll to the beginning position of the grid. Now how I solve this is by getting an instance of the ScrollViewer, I get the ScrollViewer.ContentHorizontalOffset and then I do a ScrollViewer.ScrollToHorizontalOffset after it filters.   Now here comes the problem. For 99% of the users of this xbap app, this will work absolutely fine. Most, if not all of the users run exactly the same machines, XP 64 bit with 8GB RAM. The other 1% get the error: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizontalOffset()'. I cannot reproduce this error on my own box, our dev server or our production server, it is a phantom exception that only pops up on a certain condition. I have even wrapped the "offending" code in a try catch and it still doesn't solve it. If I set the DispatcherUnhandledExceptionArgs Handled to true, it works, but it doesn't feel right. How is this possible? If the method doesn't exist, how can it compile? Why does that method exist for 99% of the other users running the exact same machines? I have googled my fingers raw without any valid results and this issue is frustrat

weird behavior in SSMS - backslash (\) is getting displayed as (#)

  

I'm experiencing some weird behavior in SSMS for SS2008.  When I create a new query and type the backslash (\) key a pound(#) symbol is displayed instead in the query window.  I've never experienced this behavior in SSMS 2005 before.  This is the first time I'm using SSMS 2008.  I work with a few developers who also use SSMS 2008 and they have no idea about this either.  Any idea whaat might be causing this behavior and any idea how I can fix this?  I'm using Windows 7 and the backslash (\) symbol displays as expected in other applications (Notepad, VS2010, etc). 

Please help!


Weird Thread.CurrentPrincipal behavior

  
msdn has a code sample illustrating the use of SetPrincipalPolicy. I copy the code and the output below:

using System;
using System.Security.Principal;
using System.Threading;

class ADPrincipal
{
    static void Main(string[] args)
    {
        // Create a new thread with a generic principal.
        Thread t = new Thread(new ThreadStart(PrintPrincipalInformation));
        t.Start();
        t.Join();

        // Set the principal policy to WindowsPrincipal.
        AppDomain currentDomain = AppDomain.CurrentDomain;
        currentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
           
        // The new thread will have a Windows principal representing the
        // current user.
        t = new Thread(new ThreadStart(PrintPrincipalInformation));
        t.Start();
        t.Join();

Weird application behavior -- Action required to trigger service response otherwise the application

  

Hi,

I am a WCF beginner and is trying out with a basic host service with callbacks to the client.

My code works wonders if my client app is a console.exe but when I transferred the code to a Windows Form app, the application will freeze.  But if I right click on the form window task bar, the code suddenly goes through and it would work...

Is there anything wrong with this?

The service is hosted on IIS

Here is my Service code:

 

[ServiceContract(CallbackContract = typeof
(IChatCallBack))]
 public
 interface
 IChat
 {
  [OperationContract]
  void
 Talk(string
 msg);
  }

[ServiceContract]
 public
 interface
 IChatCallBack
 {
  [OperationContract]
  void
 OnCallBack(string
 msg);
  }

 

Implementation:

 

[ServiceBehavior(
  ConcurrencyMode = ConcurrencyMode.Reentrant)]
 public
 class
 Chat : IChat
 {

  

Package using Recordset variable showing weird behavior

  

Hi,

I am using a recordset variable in my package... say.. User::VarRecordset(Scope: Package)

I am first filling the User::VarRecordset using a Recordset Destination. Then, I am using this Variable in a For Each Loop..

The package works fine in BIDS. Even on Making a File system Deployment, It works on My machine, and some others too.

But on Some machines, the Execution Fails, showing an Error, Package Variable "User::VarRecordset" not Found in List of Variables..

The execution results do not show any error while putting data into "User::VarRecordset" . But FOR EACH Loop Fails with that Error..

 

Unable to find any reason, why it works well on some machines and Fails on Some.

My Machine is a 32 bit one...

 

Any clue or help to this requested...

 



Thinking about new C# method prototypes: object as dictionary

  
I recently had to write a small Flickr API. I know many .Net API for Flickr already exist but I needed one for a Silverlight application. Whatever, it's only about building some querystrings so I did it by myself. It's been an opportunity to think again about a classical question: how to pass parameters to a method ?

Imagine you have a generic method to call some Flickr functions.

Custom Editing Behavior for DataGridView TextBox Columns

  
For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Ajax Tab: Each TabPanel with different Color

  

Hi,

I have situation like, Each tab panel should display with different colors based on the status. Example:

Completed tabs should display in "Green"

Inprogress status tabs should display in "Red"

Not eligible status tabs should display in "Gray".

Ajax Tab look and feel is very good. So, thought of using the Ajax Tab for my above requirement. I tried to change it. But I am not able to change the color of the each tab.  

Is it possible to change the color of each tab in Ajax Tab control? Pleas help me.

If not possible, please suggest any other tab controls to achieve above my requirement.

Note:I already tried with IE tab controls, since it provides me that flexibility to change the color of the each tab. But, It is crashing my browswer. I am not sure about the reason.

I tried Jquery option, since I need to change the tab status dynamically based on the selection made in that same page, I am not able to achieve this one in the JQuery.

Jscript error: Object does not support property or method

  

 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Run Button Behavior: Suggestion/Bug

  

Note: This could be a bug or considered as suggestion. I am not looking for solution.


1: I have ImageWatermark.cshtml open and currently in focus.

2: I have Photo1.jpg selected in left Files workspace.

3: Now if I Click "Run", instead of opening ImageWatermark.cshtml it trys to open Photo1.jpg and it fails.

So ideally I would expect the "open file (ImageWatermark.cshtml) to run rather than running the selection from Workspace.
