Hi folks,

Since I have a freshly installed version of Visual Web Developer Express, as an alternate approach, I decided to try to install DNN 4.3.4 from scratch using Michael Washinton's well document, step-by-step:  "Setting up Your DotNetNuke Version 4 Development Environment" - (http://www.adefwebserver.com/DotNetNukeHELP/DNN4_DevelopmentEnvironment/DNN4DevelopmentEnvironment1.htm)

I followed the instructions perfectly, and in fact, every one of his screens matched mine exactly (with the exception of the directory name - mine was shortened to "DNN434")

At the point that his instruction states: "The site sets up using the default settings that are set to use SQL Server Express." is where I got the following error message:

Error Installing DotNetNuke

Current Assembly Version: 04.03.04

ERROR: Could not connect to database specified in connectionString for SqlDataProvider

There was no way to reach Michael on his site, so I'm trying my luck here...

When I looked at SQL Server Management Studio Express CTP, I could not see a new database... I noticed that his instructions did not say anything about the creatiion of the database, so I thought that perhaps the script took care of this.  Perhaps not?

If anyone has gone through Michael's instructions, perhaps they can spot something missing?

Thanks!

Here is your clue: ERROR: Could not connect to database specified in connectionString for SqlDataProvider

There are two things I would do: a) Check the connection string in the web.config file to make sure it was correct. OR b) check and make sure the database exists.

Right... I had already looked into that.  The connection string was originally:

<connectionStrings>

<add name="SiteSqlServer" connectionString="Data Source=rob\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|database.mdf;" providerName="System.Data.SqlClient"/>

</connectionStrings>

So I added a database called DNN434 and changed the connection string to:

<add name="SiteSqlServer" connectionString="Data Source=rob\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|dnn434.mdf;" providerName="System.Data.SqlClient"/>

I also changed the <appSettings> add key string appropriately.

I still got this error:

ERROR: Could not connect to database specified in connectionString for SqlDataProvider

So... it sounds like the database is still not correctly set-up.  I'm looking into this, but Michael if you're reading, please make a note about this in your instructions...

Cheers!

If you use the default connection string format from DNN, you need to create your dnn434.mdf in the App_Data folder of the DNN web application. 

http://msdn2.microsoft.com/en-us/library/ms228037.aspx

Otherwise, switching to a more traditional connectiong string, without the AttachDbFileName syntax might be easier.

e.g. place something similar to this in both required locations in the web.config.

    <!-- Connection String for SQL Server 2005 Express C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\ -->
    <add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;Database=dnn434;" providerName="System.Data.SqlClient" />
