I am trying to dynamically create a web query in an excel workbook project
and am getting an error whenever I try to use a connection of type URL;

Microsoft.Office.Interop.Excel.Range range = worksheet.get_Range("A1", "A1");
Microsoft.Office.Interop.Excel.QueryTable qTable =
worksheet.QueryTables.Add(@"URL;http://localhost/SampleReport", range, null);
qTable.Name = "Test Report";

I am used C# code and this works fine from a embedded VBA module. Why not
from a .NET managed excel workbook?

Any ideas?

ps. I am getting an ArgumentException with a description of "The parameter is
incorrect"
