oh, simply put the connection code in a try catch
so u dont need to search for further ways to see if the database exists
try {
        //connect to data base
}
catch (Exception exc)
{
   ShowMessage(exc.Message)
}

It kind of depends on what you're up to, and what language you're using. Here's a snippet of C# code that will retrieve a list of all the SQL Servers available for connection:

// This part retrieves a list of all of the available SQL Servers that can be connected to
SQLDMO.Application sql = new SQLDMO.ApplicationClass();
try
{
      SQLDMO.NameList servers = sql.ListAvailableSQLServers();
      IEnumerator ServerEnumerator = servers.GetEnumerator();
      while (ServerEnumerator.MoveNext())
      {
            // Do stuff with ServerEnumerator.Current;
      }
}
finally
{
      System.Runtime.InteropServices.Marshal.ReleaseComObject(sql);
      sql = null;
}

Otherwise you can use the registry to find out what versions of SQL Server are installed. Try the following key:

HKLM\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion\CurrentVersion

This post lists some other keys to check for different versions of SQL Server: http://www.dotnet247.com/247reference/msgs/55/277144.aspx

You can also identify which MSI was used for installation: http://support.microsoft.com/?kbid=311762

I just noticed that he said he was an Access programmer. My comment probably didn't make too much sense in that context then.

I don't have any issues with the topic being closed.
