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."

ExecuteReader Requires An Open And Available Connection. ...current State Is Connecting
Apr 21, 2010Using VS 2005 and SQL Express 2005. This WinForm application runs fine on 5 out of 6 stand alone computers that is it installed on. The 6th computer is slightly older running XP sp2.As I understand it, using DbDataAdapter will perform the open, close and dispose functions for you. Therefore, Pooling should not be an issue. I am thinking that the default 15 second time out setting may be the cause?? There is some MultiThreading that will also use DbDataAdapters in the same manner but only 3-4 would be firing at the same time.The connection string is Data Source=(local)DataBase;Initial Catalog=Code;Integrated Security=True The command which throws the exception is If CodeDataAdapter.Fill(CodeDataSet.CodeTable) > 0 Then...So I am thinking that adding Connect Timeout = 60 to the connection string even though the 15 second default seems like a lifetime. Could this 15 seconds be eaten up if some other process or application takes over?

View 5 Replies.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.
