Having trouble finding much info on this error or possible solutions.As far as I can tell, the appicable permissions have all been set, on both the app folders and the framework folders. I've taken all the code out of the page to isolate

I cannot for the life of me figure out why I cannot wrtite a file to a directory inside of the website. I have this working on a Windows 2003 Server using IIS6. I've ported this web app to a 64bit Windows 2008 server and I am unable to have my web app write a file to a directory. I have shared and given security access to everything under the sun on this server to that particular folder and still no luck. My dev workstation with Visual Studio 2010 has no probelm saving a file to that directory. So it has to be something with the web server account. I am using Windows Authentication. I have an account in our Active Directory that is being used.

On my local machine I am giving path "D:/telephone_management/AMS/files/" and within files folder i m saving my text files On server machine, the drvive is E, so path is wrong. Is there any way I can dynamically get path to my files folder on server ??
View 1 RepliesI have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.
I have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind function is triggered while uploading, but after code behind function executed, we are getting this error.
View 1 RepliesI'm using DataContract/DataMembers to serialise my class to JSON for a webservice, and it all works fine, except for one of my members, which could either be class a, or class b, where class b extends class a.
If I omit the KnownType parameter, then an exception is thrown during serialisation:
Type 'ClassB' with data contract name 'ClassB:http://schemas.datacontract.org/2004/07/MyApp.App_Code' is not expected.
As expected, because the ClassB is an extension of Class A, and so not know to the deserialiser. So I need to add a known type attribute, which I do, to the parent Class which contains the member
[KnownType(typeof(ClassB))]
[DataContract]
This compiles fine, but the page which I am currently testing this on seems to go bizzare, it loads fine, however apparently the Service doesn't exist anymore, as my JS call tells me and throws and error. But I have no idea why adding the known type attribute on my class causes the webservice to apparently not exist :s
Is it something to do with the fact that my setup is ClassA, ClassB: ClassA, and all the examples I have seen, seem show a ClassA: ParentClass, ClassB: ParentClass setup.

I have a project using Crystal Reports 2008, whenever I try to print the report, using the print button on the menu I get an error on one of my machines, the Crystal Print Dialog opens, completely empty and then I get a error from windows:
Windows has blocked this software because it can't verify the publisher.
Name: PrintControl.cab
Publisher: Unknown Publisher
This is only happening on my Windows 7 machine. The solution on my Windows XP machine works fine, even if I hit the site under XP from my 7 machine, so I'm assuming something didn't install properly on 7. Any ideas? The 7 machine print dialog comes up blank, just says Print on the title and then the error comes up. The XP machine Print dialog says Print in the title and says Crystal Reports Print Control before the print options come up.
I don't know what is going on. When I try to add a tab container in my page, it allows me to do that but when I modify the code, the unknown server tag error pops up in the design view of the page.
I checked the source code to see if I had my @register clause in there, and it was there, but still the error shows. I don't know what happened, the last time it worked perfectly.
I have also recently downloaded the cute editor for .net and installed the .dlls to my bin folder and it is showing the same simtoms as well.
I am getting error when calling webservice using JSON. my code is as below

after calling the
jquery-1.3.2.min.js code it throws error on this line [Code]....the error is coming on "R"
I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".
I googled the problem and found several ideas :
check if the DLL is in Bin folder check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages check if the DLL is registered in the pages with <% @ Register ... %>
Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?
EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.
Am getting this error on clicking any of my page link.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0"
How do i avoid this error.

View 1 RepliesIn my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50);
After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus.
Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
I have created a custom user control and place Ajax editor and override the class of ajax editor to disable few buttons in editor ,
i am getting the following error
unknown server tag on the design time, and iat runtime it is working properly,

We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
The web.config file includes the following:
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode="Never" theme="esl_theme">
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.
I'm building a dynamic form using XML and XSLT. Anyway I'm using a custom asp.net control for CKEditor, it's an HTML editor.
When I try to add the controls from the XSLT using Page.ParseControl(<the-string-from-the-xslt-here>), I get a warning saying:
Unknown server tag 'FCKeditor.CKEditor'
And of course, if I remove the control from the XSLT everything is working fine and all the regular asp.net controls like TextBox etc get rendered to the string just fine. Does anyone know what I can do about it?
I have been struggling for days trying to get a simple ActiveX DLL to work with no success despite studying several articles on the subject which I have found online. I suspect I have several things coded incorrectly as I am just not familiar with this and most of the articles on the subject are out of date. I am using Visual Studio 2008 and have been using the Windows SDK V7.1 for digital signing.
What I am trying to do is return the client machineName from the environment class back to the web page (and eventually back to the web server). This is my C# class:
using System;
using System.Reflection;
using System.Runtime.InteropServices; [code]...
Note that I copied my dll to my Windows SDK folder, signed that, copied it back to my cab file which I then copied over to my SDK file, signed the cab file. Then finally, copied the cab file to my website project.
NOTE: See comments at end of first answer. I have purchased a signed certificate from Comodo and with that installed, I now get "Unknown Publisher" error even though the certificate status is "ok", Both the dll and cab file have been signed.I believe my issue now is the control needs to be marked as safe for scripting, http://www.olavaukan.com/2010/08/creating-an-activex-control-in-net-using-c/
