.net - ConnectionString Property Has Not Been Initialized?
Jul 15, 2009I've looked at a lot of posts on different forums where others have received the same error. Most say they were not referencing the connectionstring from the web.config file correctly, or they were trying to open the connection before setting the connectionstring. Well, if that were the case for me, then how does it work on two different systems, but not on the third? It works on my development PC and on the development server, but not in the production environment. The difference is the web and DB server are separate physical servers in my production environment and on a single server for development. My setup, error message and code will be listed below.
I can simulate the error on my PC if I rename the connection string in either section of the web.config file (appsettings, connectionstrings) to something else. You will see how I have tested both below.

DB/Reporting :: Connection String Property Has Not Been Initialized
Mar 3, 2008I have been given the task of debugging someone else's program. It previously ran flawlessly on a 32-bit Windows XP system, but now we are steadily switching over to 64-bit systems and this program has "spit the bit" so to speak.
This is App.Config.xml
Code:
<configuration>
<appSettings>
[Code] .....
The problem is I don't know my alternatives are. System.Configuration.ConfigurationMananger.AppSettings doesn't work.
I've tracked the problem to the last line Con.Open().
Code:
Public Function get_quotes(ByVal strDBConnection As String) As DataSet
Dim con As SqlConnection = New SqlConnection(strDBConnection)
Dim strQuery As String = "SELECT qmpQuoteID FROM Quotes"
Dim da As New SqlDataAdapter(strQuery, con)
Dim dsQuotes As New DataSet("quotes")
Try
con.Open()
The error is "The ConnectionString property has not been initialized."

Error With The Using Statement And Lazy Initialized Property
Dec 1, 2009The code below will throw an InvalidOperationException: The ConnectionString property has not been initialized. The exception is thrown at the line calling Connection.Open() in the Load method. If I use the try-finally statement instead of the using statement, everything works correctly. Can anyone explain why the exception occurs with the using statement?

I want the Name property of the Dings class to be initialised at first, I know, I could also create the foo-object (as member of dings) later in the constructor.

View 2 RepliesSelect Command Property Has Not Been Initialized Before Calling 'Fill'
Nov 27, 2011I am working on a Windows forms project that connects to a Microsoft Access database, reads the the file, does some math and then provides some basic statistics back.I am teaching myself VB and I know the code below could be more efficient.However, right now I am just trying to make it functional.The program filters the data it needs via sql, and there are several sql statements.I separated the code for each of the sql statements and into a subroutine so that I could call each one when the form loads and also when the user clicks a button to update.The program works fine on the form load, however, when you click the update button you get the following error on the 'odaCalls.Fill' in subroutine Count(): "The select command property has not been initialized before calling 'Fill'.[code]
