I have a simple peice of code that queries a database and returns a count. Everything works fine, I get all of the results that I expect, and no error messages are displayed. But, when I'm testing I noticed that my debug window is full of this message: "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"

Any idea what this is and why it's happening? What am I doing wrong?

Dim connection As SqlClient.SqlConnection
Dim command As SqlClient.SqlCommand
Dim dataObject As Object

' connectionString is built here... code not important

Try
' Open the connection
connection = New SqlClient.SqlConnection(connectionString)
connection.Open()

' Initialize the datareader
command = New SqlClient.SqlCommand("SELECT COUNT(name) AS RecordCount FROM sysdatabases WHERE filename='" & filePath & "'", connection)
dataObject = command.ExecuteScalar
recordsReturned = dataObject

' Close the connection
dataObject = Nothing
command.Dispose()
connection.Close()
connection.Dispose()
Catch ex As Exception
DisplayErrorMessage(ex)
End Try

' recordsReturned is evaluated and value is returned here
' Once again, this code is removed because it's not important

Public Sub DisplayErrorMessage(ByVal ex As Exception)
' Display the error message
MsgBox(ex.Source & ": " & ex.Message, MsgBoxStyle.Critical, My.Application.Info.ProductName)
End Sub
