Connection String Property Has Not Been Initialized Error
Aug 1, 2012
I am getting above mentioned error when I try to run the following code:
Private strConnString As String = ConfigurationManager.ConnectionStrings("conString").ConnectionString
Private con As New SqlConnection(strConnString)
Private pID As Integer
'FIRST SECTION
Dim query As String = "query"
Dim cmd As New SqlCommand(query)
[Code] .....
The error is coming from the second SQL cmd but if I comment out the first section; the second section runs fine.
I must have made another basic error but I just can't figure out what it is.

In some posts I have read on other forums, those with database connection problems (I am thinking about Access) sometimes get the error: 'Connection property has not been initialized' which might translate as 'you have not kick-started your connection'. One reason for that, according to a number of replies I have come across, is that 'you have not set the connection property of the command object' ('you have not told command how to connect').
So would something like this:
Code:
Dim conn As New OleDbConnection
Dim OleDbConnection As New OleDbConnection
Dim cmd As New OleDbCommand
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|myDatabase.mdb;"
conn.Open()
cmd = New OleDbCommand("SELECT strName FROM school WHERE strName=@strName", conn)
cmd.Parameters.AddWithValue("@strName", UserName.Text)
cmd.Connection = conn
cmd.ExecuteNonQuery()
conn.Close()
a) initialise the connection property and b) set the connection property of the command object?

I have some Class A, which is data-layer in my web-application, and I'm using A's methods to accomplish Db operations. It looks like this.
[code]...
In case when my .aspx page calls 2 methods of class A during the postback, my page throws
"The ConnectionString property has not been initialized" exception for second method call.
I tried to put _sqlcon initialization into constructor, but it still throws exception.

I am trying to setup my page with a drop down which value comes from one SQL query and item list comes from another SQL query to the same database...
what I want to do is:
read 1 line from bugs table. this line includes a projectid which will be the value of the drop down. I also read the projects table for active projects/id and load this as drop down items....
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
{
conn.Open();
using (SqlCommand bug = new SqlCommand(
"SELECT bugs.id, bugs.projectid, bugs.typeid, bugs.subtypeid, bugs.version, bugs.summary, " +
"users.email AS creator, bugs.createddate, bugs.text, bugs.closeddate, bugs.history " +
"FROM bugs INNER JOIN users ON bugs.creatorid = users.id WHERE (bugs.id = @idd)", conn))
{
bug.Parameters.AddWithValue("idd", Request.QueryString["ID"]);
try
{
SqlDataReader reader = bug.ExecuteReader();
if (reader.Read())
{
String projectid = reader[1].ToString();
// read project name list...
using(conn) using (SqlCommand projects = new SqlCommand("SELECT name, id FROM projects WHERE active=true"))
try
{
SqlDataReader pr = projects.ExecuteReader(); // This line causes the exception... what am I doing wrong?
while (pr.Read()) project.Items.Add(new ListItem(reader[0].ToString(), reader[1].ToString()));
}
catch { }

I have been looking through the event viewer on our server and can see quite a few people with this error but I can't replicate this myself but it is causing issues for people viewing our website is there anyway I can "initialize" Command Text property?
UPDATE
So I have this query
datelistquery = "SELECT DISTINCT property_id, ' - Sleeps ' + cast(number_slept as varchar) as combsleeps, number_slept FROM openquery ("+Application("hpbDsrc")+",'SELECT property_id, number_slept FROM web_details WHERE part_full_flag = ''F'' AND location = ''"&Session("TenChosenLocCode")&"'' AND property_id = ''"&Session("passedPropId")&"'' AND pets_yn like ''"&Session("TenPets")&"'' AND number_slept >= ''"&Session("TenAdults")&"'' AND year_week = ''"&Session("TenHolStDateHP1")&"'' AND on_hold = ''NO'' AND booked = ''NO'' ') ORDER BY number_slept, property_id"
So should I put at the start sqlCommand.CommandText(datelistquery) = "Select Distinct...."

I need to configure a property of a custom control I wrote, specifically before the control calls OnInit. If I assign it as part of the ASPX file, it naturally works, but if I instead move the assignment to different parts of the code-behind, it will throw an error for having an empty and invalid value. The following is what it looks like when functional in the ASPX page.
<MyCustomControls:SingleCascadeLookupMulti FilterString="Seventh" FilterByStatus="true" ControlMode="New" FieldName="Speciality" EnableViewState="true" ID="sclmDocuments" runat="server" TemplateName="SingleCascadeLookupMulti" />
The property in question is FilterString, which is just a simple string. It should be noted as well that the FieldName property (inheritted from the control's base class "BaseFieldControl") would also throw an error if it is not initialized, but if I set FieldName in the code behind's OnInit method, it works correctly. FilterString is not so, it won't actually be assigned. So I know that some methods for certain properties will work for setting the property's value, but it won't always work. I tried placing it in OnPreInit as well, to no avail.
I am taking a dynamic assignment approach because the functionality of this page needs to be replicated for a number of different lists, and the FilterString and FieldName properties will differ in every case. Rather than write half a dozen mostly-identical aspx pages all with the same code behind but differing just in what those two properties are, I figured it would be wiser to use the page's query string and some derived parameters to set those properties dynamically. As such, what methods are available to accomplish this task?

I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

I have set up a small SQL Server database for users to login and also create accounts. There is a problem with the connection string though. Whenever I use the connection string below in the web.config file I get a server error page and cannot view the website. However when I take out this connection string I am able to view the website albeit the database doesn't work.

I'm loading a .aspx page via fancybox (ajax loading mode).I was using fancybox 1.2.6, working fine, then upgraded to fancybox 1.3.4 and IE now triggers the JS error above (in the subject of the post). Then why am I posting on ASP.net forum you might ask?!?... read on...Debugging the JS code, the error happens inside jQuery in the .html(data) function where it does a evalScript .each scripts inside data. jQuery version is 1.4.2.I'm able to resolve the problem by editing fancybox-1.3.4.js at line 265. I just use innerHTML to circuvent the evalScript that occurs inside html()... and it works:
//tmp.html( data ); <-- original code commented out where JS error occured
var tmpDiv = tmp.get(0); <-- new "plaster" kind-of fix
tmpDiv.innerHTML = data; <-- new "plaster" kind-of fix
Why I'm posting on ASP.net and not on jQuery nor fancybox groups is that I consider that the proper fix would be in the .aspx that is loaded via ajax.To summarize the problem. There is a base .aspx page that has a couples of text and buttons. When you click a button, it loads via AJAX a new .aspx page (using fancybox). You end up with two ScriptManager js code and it triggers an error when executing :
//<![CDATA[
Sys.WebForms.PageRequestManager._initialize('ctl00$ScriptManager', document.getElementById('aspnetForm'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);

I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.
