Audio or Sound Card problems in Windows 2003 Server (especially when remoting)

Gokulnath — Thu, 06 May 2010 22:53:56 GMT

If audio is not working in your server, check whether Windows Audio service is started…

How to do:
1. On Windows Run (windows key + R key), type services.msc
2. Look for Windows Audio service and check whether it is started, if not, start it

If this doesn't resolve your problem, try updating your audio drivers.

If audio is not working only when remoting, try the following:

1. On Windows Run (windows key + R key), type gpedit.msc
2. Go to Local Computer Policy/Computer Configuration/Administrative Templates/Windows Components/Terminal Services/ClientServer redirection
3. Enable Allow audio redirection

and then do this too:
1. On Windows Run (windows key + R key), type tscc.msc
2. Open the Connections folder in the left sidebar
3. Right-click RDP-Tcp, select Properties
4. Click Client Settings tab
5. UNCHECK the "Audio mapping" checkbox under the section "Disable the following:"
7. Click OK, and close tscc
8. You may see a warning which says this change will not take effect for any currently-connected RDP sessions. Click out of that
9. Logoff
10. Login

If you are remoting from a Windows XP machine, try to remote into the console by typing "mstsc /console" on run window.
If you are remoting from a Windows 7 or a Vista machine, try to remote into the console by typing "mstsc /admin" on run window.

Take Ownership and Grant Permissions in Windows 7

Gokulnath — Wed, 05 May 2010 04:15:42 GMT

After upgrading my PC from Windows XP to Windows 7, an external hard drive which was working fine on XP lost write permissions.

Found a solution:

1. Right click on the drive icon for the external drive.
2. Select Properties
3. Click Security Tab
4. Click Advanced Button
5. Click Owner Tab
6. Click Edit Button
7. Choose your account or administrators group, whichever you want to give permissions
8. Check 'Replace owner on subcontainers and objects'
9. Click OK

If this doesn’t resolve your problem, choose the user from “Group or user names” list, click “Edit”, and give appropriate permissions.

Hope this works for you!

Accessing TFS 2010 using Team Explorer 2008 Client

If you are getting “None of the products that are addressed by this software update are installed on this computer. Click cancel to exit setup” (the popup below) while trying to install Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 (this allows to use the Team Foundation Server 2010 server with Team Explorer 2008 SP1 client) , first install VS 2008 SP1 (not 3.5 SP1) and then try installing the compatibility update.

Regular space and html space (ascii 32 and 160 respectively)

Gokulnath — Wed, 09 Dec 2009 20:44:20 GMT

Can anybody find the difference between the first and the second ‘testing abc’ in this file test.txt (.02 KB). Open the file and search for ‘testing’ (there should be 2 matches), ‘abc’ (2 matches) and then ‘testing abc’ (1 match). It is because the ‘space’ between the two words varies, one is a regular space and the other is a html space (not nbsp), their ascii values are 32 and 160 respectively. I figured this after converting the spaces to ascii values! (spent almost an hour)

Take an asp.net application offline easily

Gokulnath — Wed, 09 Dec 2009 20:36:59 GMT

We can take an ASP.NET 2.0 application offline temporarily by uploading a file called app_offline.htm to the root directory. It will shut-down the application, unload the application domain from the server, and stop processing any new incoming requests for that application.

Working around the "IE Friendly Errors" feature - http://weblogs.asp.net/scottgu/archive/2006/04/09/442332.aspx

I came to know this only today when I was listening to Hansel minutes, this will definitely help me in taking my website down easily.

ASP.NET menu control - hiding root node and arrow image

Gokulnath — Wed, 09 Dec 2009 16:28:18 GMT

This is for my future reference.

If you are using sitemap as the data source for the menu control, then you can set the property ShowStartingNode = "false" of sitemapdatasource. Inorder to hide the arrow image, set the properties DynamicEnableDefaultPopOutImage = "False" and StaticEnableDefaultPopoutImage = "False" of the menu control.

Choose Items in Visual Studio Toolbox crashes Visual Studio

Gokulnath — Mon, 16 Nov 2009 15:04:38 GMT

I was trying to add AJAX Control Toolkit to my Toolbox, for some reason Visual Studio was crashing. I found a solution for it, see this works out for you – start Visual Studio in safe mode (go to Visual Studio’s command prompt and execute ‘devenv /safemode’) and then try to add items to your toolbox, I was able to do it! There might be a better solution for this, please let me know if there is one.

Postback problem on a modal popup or Session transfer to a popup or a page opened from another popup

Gokulnath — Fri, 23 Oct 2009 11:07:04 GMT

Solutions for postback problem:
1. Add "<base target = “_self” />" inside <head> tag of the popup.
2. You can use window.open instead of window.showModalDialog.

Solutions for session transfer problem:

1. You can use window.open instead of window.showModalDialog.

2. You can use AJAX modal popup.

This seems to be a IE bug (working fine in firefox and chrome), I have this problem if I open the .NET application after opening an instance of IE (say google.com) whereas if I open the former before the latter, things are fine.

Please let me know if anybody has any good solution for this.
