‘Sys is undefined’ Error in .NET 2.0 and AJAX 1.0 Extensions

If you’re using ASP.NET 2.0 and try to use ajax, you may experience the error ‘Sys is undefined’. If this is the case for you, you’re most likely just missing some configurtion settings in your web.config. To fix your web application, just copy and paste the web.config settings that are missing in your app’s web.config file from the web.config file that’s in ASP.NET Extensions directory (mine is C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025).

Start Button App for Windows 8

I’ve been using Windows 8 since the Consumer Preview and have really grew to love it. I’ve seen a lot of posts about people wish they could still have their start button in windows 8. Below is a freeware app I wrote for myself in .NET 4.5 that will provide similar functionality.

Here’s how you install it:

1. Download the StartButtonApp.zip files below and extract it to your desktop

2. The zip program should create a directory called StartButtonApp and in that directory there should be a StartButtonApp.exe file

3. Right click the StartButtonApp.exe and click Pin to Taskbar

4. Move the StartButtonApp icon to the desired location on your taskbar and you should be all set

Click this link to download the app:   StartButtonApp.zip (7.88 kb)

Have fun with it and happy holidays! 🙂

That’s it, test your ASP.NET app and it should compile and run error free.



Install Cisco AnyConnect VPN on Windows 8 x64

I’ve tested this on Windows 8 Pro x64 only (I’ve not tested this on x86 versions of Windows 8). Please make sure to backup the registry key we are going to modify in the instructions below before modifying it.

1.    You company will give you a URL where you can install the Cisco AnyConnect VPN Client from… In Windows 8 you might get “Page cannot be displayed” if you try to load the website via Internet Explorer 10. To properly install it successfully, useFirefox (IE will not work, not sure about Chrome)

2.    Edit your registry by pressing Windows Key + R

3.    Type RegEdit then press Enter

4.    Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vpnva

5.    Double click on the DisplayName

6.    Delete everything before “Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64” and save the DisplayName value

7.    Test your VPN client and now you will no longer get a VPN driver error that you were getting on Windows 8


EDIT:   After a reboot, I received an error message but was able to get passed it by performing the following:

  1. Open the Services MMC (Window Key + R then type “services.msc” and press enter)
  2. Stop the Internet Connection Sharing (ICS) service
  3. Open the Cisco AnyConnect VPN Client and login



Change Windows 8 Enterprise to Windows 8 Pro

You can’t change the CD Key of Windows 8 Enterprise by going to the System screen. To change Enterprise to Pro, you need the Windows 8 retail CD along with your windows 8 Pro CD KEY. Popin the CD in your computer and reinstall windows however, when prompted what you want to do with your apps, files, and settings make sure you select the KEEP Settings, Apps, and Files!! It should be the default selected checkbox but make sure just in case.

Hope this helps other folks out there.

Could not load file or assembly ReportingServicesNativeClient

If you experiencing error “Could not load file or assembly ReportingServicesNativeClient” when you try to access Report Manager and/or Report Server in your SQL Server 2005 Reporting Services deployment, it’s most likely due to the fact that your Application Pool is configured incorrectly. More than likely you recently executed “cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1” for some other project which ended up affecting SSRS without you even knowing it.


Here’s how I fixed this issue in my SSRS environment (please make sure to test this solution in your test environment before trying it on your production environment):

1.   Open IIS Manager 7+

2.   Click Application Pools

3.   Select “ReportServer” from the list of app pools then click Advanced Settings

4.   Under the General section find the property named Enabled 32-Bit Applications and set that to False

5.   Register x64 version of ASP.NET – C:\Windows\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis.exe -i

6.   Restart IIS

7.   Test Report Manager


If it still doesn’t work:

1.   Open the SSRS Configuration Tool and connect

2.   Click Report Server Virtual Directory

3.   Check mark Apply default settings then click the Apply button

4.   If the Web Service Identity doesn’t show a green checkbox, click on it then make sure both Report Server and Report Manager are both set to the ReportServer app pool


That should do it.



BizTalk Server 2009, RosettaNet Accelerator, & Client Certificates


By default, the RosettaNet Accelerator in BizTalk Server 2009 does not support sending Client Certificates via BATRNApp/RNIFSend.aspx. To achieve this functionality, you need to download the Elemica Connectivity Pack from MSDN. The Elemica Connectivity Pack contains a modified version of the Microsoft.Solutions.BTARN.RNIFSend.dll which can be tweaked to send your Client Certificate.

You can download the Elemica Connectivity Pack from MSDN at:


How to customize our new Microsoft.Solutions.BTARN.RNIFSend.dll

1.       Run the BTARN30 Elemica Connectivity Packe.exe to extract the files.

2.       Next, Open the RNIFSend project

3.       Sign the project with a Strong Name (if you don’t know how to do this, check this article out http://msdn.microsoft.com/en-us/library/xc31ft41.aspx)

4.       Build the project (make sure the configuration is set to Release)

5.       Open IIS, expand websites and find the BTARNApp virtual directory…

6.       Right click it then click Explore to open the physical folder in Windows Explorer (by default it is located in \Program Files (x86)\Microsoft BizTalk 2009 Accelerator for RosettaNet\RNApp)

7.       Backup your RNApp directory

8.       Next, copy the Microsoft.Solutions.BTARN.RNIFSend.dll that you built in step 4 above to the \RNApp\bin directory (when prompted to overwrite, click Yes)

9.       Open the web.config file located in the RNApp directory

10.   Add the following key/value pair to the appSettings section (if the appSettings section doesn’t exist just add it) to the bottom (right before the </configuration> element). Make sure to change the certificate path/filename to the one you want to use.


    <add key=CertificateFile

value=D:\BizTalk Client Certificate\YourPublicCert.cer />


11.   Save the web.config file but make sure your certificate is in the path you specified. Also, please make sure the certificate you selected is capable of Client Authentication. You can check that in the Certificates MMC by right clicking your certificate then looking at the Certificate Purposes list.

12.   In IIS, assign the user that is used by the Host Instance (in the BizTalk Administration Console) to the IIS App Pool associated with your BTARNApp virtual directory

13.   Restart IIS

14.   Restart the BizTalk Host Instance

15.   Test it

Turn on Tracing to debug your BTARNApp

One of the coolest tools I found that helped me was turning on tracing to see what was actually going in and out of the BTARNApp web app. To turn on tracing just add the following code snippet to the RNApp/web.config file (you don’t need to copy the configuration elements):




    <trace autoflush=true />


      <source name=System.Net>


          <add name=System.Net />



      <source name=System.Net.HttpListener>


          <add name=System.Net />



      <source name=System.Net.Sockets>


          <add name=System.Net />



      <source name=System.Net.Cache>


          <add name=System.Net />





      <add name=System.Net type=System.Diagnostics.TextWriterTraceListener initializeData=c:\traces\BTARNApp.log traceOutputOptions=DateTime />



      <add name=System.Net value=Verbose />

      <add name=System.Net.Sockets value=Verbose />

      <add name=System.Net.Cache value=Verbose />

      <add name=System.Net.HttpListener value=Verbose />







addEventListener Error Internet Explorer

Are you sick and tired of getting that annoying debugger break in Visual Studio caused by the addeventlistener Null Object Reference exception!? Well, after tons of googling I still couldn’t find the resolution. What I noticed is that after doing Windows Updates sometimes after the PC restarts the error would stop (for a short time). For me the error was occurring on Internet Explorer 9 but it’s possible that you may experience the same symptoms on prior version of the IE.


1.       Open Internet Explorer 9

2.       Click the Tools menu (if you don’t see it, don’t worry, just hit the ALT key on your keyboard and it will appear) then click Manage add-ons

3.       In the list of addons on the right pane, click on any add-on then press CTRL+A (this will select all your add-ons… also you may want to take a screenshot or write down which add-ons you have enabled so that you won’t forget which ones you had enabled)

4.       Next, click the Disable All button at the bottom right hand side of the screen


5.       Click the Close button

6.       Open Visual Studio .NET and load up the website that you know causes the addeventlistener error and vuala, no more error!


At this point what I did is enable each add-on one by one and test my project to try to figure out which one was causing the exception (in my case the add-on was called “Discuss”).


I hope this article was helpful, happy programming! J


Management Studio 2012 – Save Table Changes

In SQL Server 2008/2012 the default table designer behavior is to disallow you from saving changes to table that require the designer to delete and recreate your table. In SQL Server 2005 SSMS the default setting allowed you to save your change by acknowledging a message prompted. If you’d like SSMS 2008 or 2012 to behave the same way your SSMS 2005 did, just follow these simple steps:

1.    Open SQL Management Studio

2.    Click menu Tools > Options

3.    In the Options window click Designers

4.    On the right pane, uncheck the checkbox that says Prevent saving changes that require table re-creation

5.    Click the OK button

You should be all set at this point. Test it out by opening the table designer, making your changes, and saving them.


SQL Management Studio 2012 (SSMS) Keyboard Shortcuts

So I’ve installed SQL Server 2012 on my Windows 7 machine and have encountered an unexpected issue that drove me absolute bonkers. I make extensive use of keyboard shortcuts for comments code, showing/hiding results panes, auto formatting code, etc… In the new SQL Management Studio much to my surprise, the good old fashion CRTL+R shortcut to toggle the results pane did not work. My first instinct was to try different combinations of shortcuts like CRTL+R+R or CRTL+D+R etc… Nothing worked. So I did some googling and found the following MS article http://msdn.microsoft.com/en-us/library/ms174205.aspx which states that the Ctrl+R shortcut is suppose to work.

Luckly, after some more searching I stumbled upon this MSDN blog http://blogs.msdn.com/b/managingsql/archive/2011/07/13/enhanced-keyboard-shortcuts-in-ssms-in-denali.aspx which helped me figure out how to fix it. What I learned is that SSMS 2012 ships with two different keyboard schemes “Default” and “Visual Studio 2010 Compatible”. Even though mine was set to Default, my Ctrl+R shortcut still didn’t work. So let me cut to the chase, here’s how you fix it:

1.    Open SSMS 2012

2.    Click menu Tools > Options

3.    Expand Environment > Keyboard

4.    Select “Default” if it isn’t already and click the Reset button

5.    Click the OK button


At this point, you can test your shortcut and you will find that it now works as expected.
