Unhappy INSERT permission failed (p 28)

Hey everybody,

I'm trying to get the Insert button to work on p. 28. My code compiles correctly, it just looks like a database error on the back end. What should I be doing with SQL Server? Do I need to add a special user for this application? Do I need to add some permissions inside this application that I've just missed?

Default Had same issue - stopping me from moving forward.

I have had the same issue. Here are some details.

I created the website as suggested in Ch 1 and went through the steps as carefully as I could.

However, one difference - I created the database in SQLServer 2005 Developer first and ran the script with additional data provided in the FinalDBScriptWithData, so was starting with a precreated database. The database was created to use Integrated Security.

However, for the web site creation, in the Readme.txt of the downloaded code, it states: "When creating the virtual directory in IIS you must disable Annoymous access to the site and enable Integrated Windows authentication."

I checked the settings of the IIS Virtual Dirctory for these and they did not appear to be set by Visual Studio after the solution creation following Ch 1 instructions as the readme stated they should be.

I have tried to run the Ch 2 code both as it was created with Anonymous Access enabled and disabled.

To disable the Anonymous Access, I opened the virtual directory properties dialog from IIS management app, and under the Directory Security tab, clicked the Edit... button to edit the Anonymous access and authentication configuration. I unchecked the "Anonymous access" checkbox and checked the "Integrated Windows Authentication" checkbox.

After going through the creation of the p 28, and selecting view in Browser, I first get a logon dialog though which I log on with my username and password for my local machine (I was surprised to get this...).

Then when I click the button I get the following error message:

Server Error in '/SPSLFF08UI' Application.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Default One solution that worked.

From a different thread, Login failed for user 'NT AUTHORITY\NETWORK SERVICE' I tried adding the following line to the web.config file in the <system.web> section:

<identity impersonate="true" />

Apparently, even though you can set up both SQL Server to use Windows Authentication and the Website to use Windows Authentication, when the website actually runs, it runs under a different account (the ASPNET account in my case). The instruction above causes it to use the client login as the identity of the process. See http://msdn.microsoft.com/en-us/libr...(v=vs.71).aspx and http://msdn.microsoft.com/en-us/libr...(v=vs.71).aspx.

This fixed it for me. I don't know if there is a better solution out there - I would have thought that following the instructions in the book were sufficient. Does anybody know of a higher level setting somewhere which might affect this behavior?
