SSAS: Unexpected error occured: 'Error in application.'

What happen?
I'm new to this SQL Server Analysis Services cube processing and have been working on this project for a month plus.
Gotten into this error when trying to browse the Cube Calculation tab.

Unexpected error occured: 'Error in application.'

Software: Visual Studio 2005
Operating System: Windows 7

What's the problem?
This might be caused by version mismatch between some binaries of msmdlocal.dll and msmgdsrv.dll.

The Solution?
Manage to get help from Internet Search engine and route to this page:
http://social.msdn.microsoft.com/forums/en-US/sqlanalysisservices/thread/773988a0-1767-47ed-9405-77430e7db37f/ Making sure that the ones installed into %ProgramFiles%\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\ are the same as those in %ProgramFiles%\Common Files\System\Ole DB\
(if they are not then try updating the ones in the PrivateAssemblies with the ones from ole db; you might want to save the original ones as to be able to get back to original state just in case...)

Server Application Unavailable

What is happening? Out of a sudden, when accessing asp.net website, this error message is showing up instead of a normal webpage.

Oh my god... Checked on the IIS, every setting is correct, verify file is there, permission is correct as well.

I even tried setting Everyone's permission to Full control but this is not solving the problem.

So my next step?
Re-registering aspnet_regiis.exe -i
(c:\windows\microsoft.net\framework\v2.0.50727\aspnet_regiis -i )

And Voila, everything works back to normal. YAY!!!

HTTP Error 404 - File or Directory not found

What happen?
Encountered this problem on my VPC (Virtual PC), Windows 2003, IIS 6.0.
When I try to view default.asp or default.aspx file, nothing seems to work.
The error returned in the browser was:

HTTP Error 404 - File or Directory not found.

Search the web and found this useful site from microsoft which explains why it happen and the solution: http://support.microsoft.com/kb/315122

What's the problem?

When you request dynamic content such as an Active Server Pages (ASP) page, an ASP.NET page, an Internet Services API (ISAPI) application, or a Common Gateway Interface (CGI) application on a Microsoft Windows Server 2003 server that is running Internet Information Services (IIS) 6.0, you may receive one of the following error messages:

• Error message 1
  HTTP Error 404 - File Not Found
  
• Error message 2
  HTTP Error 404- File or Directory not found

Cause?
By default, when IIS is installed on any version of the Windows Server 2003 family, IIS only serves static content (HTML).

The Solution?
Enable a Pre-existing Web Service Extension in IIS 6.0

To permit IIS to serve content that requires a specific ISAPI or CGI extension that is already listed in the Web service extensions list, follow these steps:

• Open IIS Manager, expand the master server node (that is, the Servername node), and then select the Web service extensions node.
• In the right pane of IIS Manager, right-click the extension that you want to enable. In this example, this is Active Server Pages.
• Click to select the Allow check box.

Error '80040211' When Sending Email in ASP

All this while, the web server used to host a web application that sends out email when a request is submitted suddenly couldn't send email anymore.
Error returned was this weird figure: Error '80040211'.

Seek my best buddy help: Google and found this link:

Based on the forum, what that guy did is basically change the 'sendusing' fields from 2 to 1.
I tried and the trick works. ^_^

And from the explanation from MSDN
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/bb2a4e60-080f-49bf-be71-e2a7e52ce5ad.asp

cdoSendUsingPickup (value 1)
Send message using the local SMTP service pickup directory.

cdoSendUsingPort (value 2)
Send the message using the network (SMTP over the network).

Couldn't convince myself why this happens since my web server is over the network, but it works. Let's put this on for now, while I'm busying with another project at the moment.

ERROR: Object reference not set to an instance of an object

Problem occurs after the reinstallation of IIS in the web server (since out of a sudden --> might be due to a patch, the IIS is corrupted).

Accessing ASP page works fine in the localhost, but gives this error when accessing .Net page
"Object reference not set to an instance of an object".

Googled the web and found few links that teach on how to solve:

1. Support from Microsoft: http://support.microsoft.com/kb/810098

2. Common causes in VB.net: "http://codebetter.com/blogs/raymond.lewallen/archive/2005/06/23/65033.aspx"

3. Re-registering aspnet_regiis.exe -i: http://dev.communityserver.com/forums/p/474748/531732.aspx

Item #1 and #2 didn't fix my problem, but the #3 did.

Basically, to prevent this error, you need to install IIS before install .Net Framework. If you did the reverse way, the .Net framework somehow are not registered in IIS. Therefore, you need to run the command again "aspnet_regiis.exe -i" to install it.

Screenshot of running the command in cmd prompt:

ERROR: Components required to enumerate web reference are not installed in V2008

Attending a WCF .Net Framework 3.5 training and came across this error when trying to add Service Web Reference.

"The components required to enumerate web references are not installed on this computer. Please re-install Visual studio"

It is kinda weird as I have a full installation of VS2008 on my computer but somehow it says it is not installed. How come?

What I did:

1. I actually try to reinstall VS 2008. Then open up the project again and try to add Service Reference. --> RESULTS: Still FAIL.


2. Google up. Found this magic word "devenv /resetskippkgs". Pump this word into the command prompt. Voila. ---> RESULTS: It SOLVES my problem. (Note that run this magic word on the folder where you installed the VS. In my case, it's "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE").

Solution: Follow step #2 and skip #1.
