Clue - Who dun it? The Data Adapter, DataSet, SqlSelect etc...

Ok, I know my connection string and config file are good. Once the rest of the code is added I receive this error:

"SQL Server does not exist or access denied. "

I'm using the 1.1 framework and my hosting company provides MSSql 2005.

Thanks for your time,

Charlie

If you are receiving that error, it generally means that your connection string is NOT good. Check out this KB article:Potential causes of the "SQL Server does not exist or access denied" error message.

That string was pasted in from another page on the same host. It works fine there. Why should I not assume that it's good?

Hello,

Something I just noticed in the stack trace.

 
 blog.WebForm1.Page_Load(Object sender, EventArgs e)in c:\inetpub\wwwroot\blog\index.aspx.cs:31
 

 this is still referencing my local machine. How can I change this?

Hi,

From your code, I can see your connection string is:

Server=xxx.xxx.xxx.x;Database=myDataBase;User ID=myID;Password=myPass

Please check if your server address is correct. Is the SQL server you're connecting to a default instance or a named instance. If a named instance, please try to use Server=xxx.xxx.xxx.xxx\InstanceName

also, please check the login name and password. You can try to create a .udl file for testing. Here are the steps:

1. Create a Text file.
2. Rename it to .udl
3. Double click on the file, and test in the Data Link Properties window.

HTH.

I believe I found the issue. This being my first attempt to host a .net web app on a ISP, it didn't occur to me that modifying the connection string in the provided online text editor wouldn't be sufficient. Simply put, I needed to recompile my app.

Thank-you all for your support.
