After publishing the site, you have to deploy the site on IIS, and does not mean that just putting the code on wwwroot.

Do the Following Steps :
1. Published the code.
2. Put the code into wwwroot
3. Open IIS > You will see there should be a folder with the name of your web application
4. Right Click on that and Click on Properties.
5. Click on Create Virtual Directory Folder.
6. Set additional Setting if you need
7. Then try to access using http://localhost/virtualdirectory/home.aspx

Let me know if you have any issue.

That because you didn't set the framework version in Virtual Directory Properties. Goto the properties of the virtual directory, then go to ASP.NET Tab, check the asp.net version, If your web application developed in asp.net 2.0 then it should be 2.0.x.x .
Set that, apply and try again !!

It will work.

What do you mean by meta base ? Can you tell me what actual error are you getting ? Are you able to view your page now?

Did you try that What CG has already Suggested ?

You have installed IIS before or After Installing .NET Framework ? It seems, your IIS is not registred with ASP.NET .

Run the following command :

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i

[ Note : I assumed the your framework has installed the following location ]

Then Try.

This will resolve your issue.

I believe this means that ASP.NET is not installed for IIS.

Re: Problem of report in excel

5-Jul-09 0:33

Hello every one

I need to develop an application in asp.net where i had to make report in excel for that i wrote my code like

Dim xl As New Excel.Application
 xl = CreateObject("Excel.Application")
        xl.Workbooks.Add()
        xl.visible = True

this code works with vb.net 2005 but the same i want to use in asp.net 2008

so please help me how to approach

I am new to asp.net 2008.

I am guessing you did this in the past via some code you found online and have no idea how it worked. The Excel stuff is not built in, you need to download the toolkit for it from MS. Also, you need Excel to be installed.

You will create an Excel sheet on the server and users will download it ?
