Download and Share Visual Studio Color Schemes

The good news is that Visual Studio allows you to completely customize the editor background and text colors to whatever you want - allowing you to tweak them to create the experience that is "just right" for your eyes and personality. You can then optionally export/import your color scheme preferences to an XML file via the Tools->Import and Export Settings menu command.

Ajax Tab: Each TabPanel with different Color



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.

Using loginName to find ADInfo from an outside class



I wrote a class to pull adinfo and for the life of me I can't seem to figure

out why it says "Invalid Login Name" no matter what I type in. If I leave

it blank it seems to work properly but it doesn't seem to be actually searching

the AD. I'll drop the whole class here, it's being initiated by a button click

on an outside form.


Thanks in Advance for any help Offered,

LDAP - Can't find server


Hey people,

I would like to get a persons name from their username - a common query on forums i know, but i haven't managed to get mine working yet and any help would be appreciated.

I currently have this code that I found here: http://www.vbforums.com/showthread.php?t=612655 (Thanks Chris128)

I have adapted it from VB into VB.net. The page renders but when i enter my username into the Username textBox and hit the submit button (Which calls IsUser) I just get "The specified domain either does not exist or could not be contacted." I have tried lots of other code but I always get this response...

If anyone can help by posting links to a tutorial or another post for code that they know works, i will give it a go.

Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap



I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

<binding name="CurrencyServiceSoap" closeTimeout=

Asp to asp.net cant find Msxml2.XMLHTTP


Hi all i have this following code in asp and when i try this in .net it asks me to run in aspcompat=true mode which i dont want.
So i tried to DIM x as Msxml2.XMLHTTP but its not defined any suggestions on this. Thanks

xmlhttp = Server.CreateObject("Msxml2.XMLHTTP")
        On Error Resume Next
        xmlhttp.Open("POST", "https://xxxxx.cgi", False)

System.DateTime.AddDays: Value to add was out of range.


I'm getting the following error:

[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
   System.DateTime.Add(Double value, Int32 scale) +7657639
   System.DateTime.AddDays(Double value) +19

The line from which this error originates has the following code:

expires = Now.AddDays(30)

It occurs irregularly and irreproducably. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative.

It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Any ideas? Culture settings perhaps?

Hi guys

This is driving me crazy... I cant find the .vsi file for installing the CSS Friendly Control Adapters Project. Does anyone know where I can get this?

The following link: http://www.asp.net/cssadapters/ only leads to the CodePlex wiki where I can download the dll and a partial solution. Essentially, I'm looking for the source code to implement the Menu adapter.

Any help is much appreciated!
