Connection Property Not Initialized

Feb 9, 2006

Hi,

I'm trying to do a database operation in ASP.NET page using the following code:

string connString = "SERVER=localhost;DATABASE=chbr;UID=sa;PWD=password;Connection Timeout=120";
SqlConnection sqlConn = new SqlConnection(connString);
sqlConn.Open();

string commandStr = "...";  

SqlCommand command = new SqlCommand(commandStr); 
  
command.ExecuteNonQuery();
sqlConn.Close();

But I kept getting the exception saying "ExecuteNonQuery: Connection property has not been initialized."

What did I do wrong?

Thanks!

ExecuteNonQuery: Connection Property Has Not Been Initialized

Feb 9, 2005

I am trying to create a web form that will be used to create new users. The
first step that I am taking is creating a web form that can check the
username against a database to see if it already exists. I would it to do
this on the fly, if possible. When I execute my current code, I get the
following error:

ExecuteNonQuery: Connection property has not been initialized

Below is the code from the page itself:
-----
<!-- #INCLUDE FILE="../include/context.inc" -->
<!-- #INCLUDE FILE="../include/db_access.inc" -->

<script language="VB" runat="server">

Sub CheckButton_Click(Sender as Object, e as EventArgs)

Dim result As Int32
Dim cmd As OdbcCommand

cmd = new OdbcCommand( "(? = CALL CheckUserExists(?))", db_conn )
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add( "result", OdbcType.Int ).Direction =
ParameterDirection.ReturnValue

cmd.Parameters.Add( "@userName", OdbcType.VarChar, 100 ).Value =
Request.Form("userName")

cmd.ExecuteNonQuery()
result = cmd.Parameters("result").Value

If result <> 1 Then
CheckResults.Text="<font color=""#ff0000"">Username already
exists!</font>"
Else
CheckResults.Text="<font color=""#009900"">Username is
available.</font>"
End If

end Sub

</script>

<html><body>
<form runat="server">
<asp:TextBox id=userName runat="server" />
<asp:Button id=CheckButton runat="server" Text="Check Username"
onClick="CheckButton_Click" />

<p>
<asp:Label id=CheckResults runat=server />
</form>
</body></html>
-----

Can anyone see why I might get this error? Here are some more details of
the error:

Line 15: cmd.Parameters.Add( "@userName", OdbcType.VarChar, 100 ).Value =
Request.Form("userName")
Line 16:
*Line 17: cmd.ExecuteNonQuery()
Line 18: result = cmd.Parameters("result").Value

Thank You,

ExecuteReader: Connection Property Has Not Been Initialized.

Mar 11, 2005

I have a web form that is generating an error and I can't seem to figure out why for the life of me. Below is the code:


Private Sub VerifyNoDuplicateEmail()
Dim conn As SqlConnection
Dim sql As String
Dim cmd As SqlCommand
Dim id As Guid
sql = "Select UserID from SDCUsers where email='{0}'"
sql = String.Format(sql, txtEmail.Text)
cmd = New SqlCommand(sql, conn)
conn = New SqlConnection(ConfigurationSettings.AppSettings("cnSDCADC.ConnectionString"))
conn.Open()
Try
'The first this we need to do here is query the database and verify
'that no one has registed with this particular e-mail address
id = cmd.ExecuteScalar()
Response.Write(id.ToString & "<BR>")
Catch
Response.Write(sql & "<BR>")
Response.Write("An error has occurred: " & Err.Description)
Finally
If Not id.ToString Is Nothing Then
'The e-mail address is already registered.
Response.Write("Your e-mail address has already been registered with this site.<BR>")
conn.Close()
_NoDuplicates = False
Else
'It's safe to add the user to the database
conn.Close()
_NoDuplicates = True
End If
End Try
End Sub

Web.Config
<appSettings>
<!-- User application and configured property settings go here.-->
<!-- Example: <add key="settingName" value="settingValue"/> -->
<add key="cnSDCADC.ConnectionString" value="workstation id=STEPHEN;packet size=4096;integrated security=SSPI;data source=SDCADC;persist security info=False;initial catalog=sdc" />
</appSettings>


Can anyone show me the error of my ways?

Thanks,

System.InvalidOperationException: ExecuteReader: Connection Property Has Not Been Initialized.

Jan 29, 2008

Hi,

I have written a CLR Function in C#. The function works as expected except that I am trying to read data some data during the function call and get the following error:


Msg 6522, Level 16, State 1, Line 1

A .NET Framework error occurred during execution of user-defined routine or aggregate "fn_SLARemaining":

System.InvalidOperationException: ExecuteReader: Connection property has not been initialized.

System.InvalidOperationException:

at System.Data.SqlClient.SqlCommand.ValidateCommand(String method, Boolean async)

at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result)

at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)

at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method)

at System.Data.SqlClient.SqlCommand.ExecuteReader()

at SLARemaining.SupportTimes.addSupportHours()

at SLARemaining.CalculateTimeRemaining.GetTimeRemaining(String openDate, Decimal SLADuration)

at UserDefinedFunctions.fn_SLARemaining(SqlDateTime DateFrom, SqlDateTime DateTo, SqlInt32 PriorityTime, SqlDecimal AdjustmentTime, SqlDecimal Status)

.


The main code for the function is this:


using System;

using System.Data;

using System.Data.SqlTypes;

using System.Data.SqlClient;

using Microsoft.SqlServer.Server;

public partial class UserDefinedFunctions

{

[Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read)]

public static SqlString fn_SLARemaining(SqlDateTime @DateFrom, SqlDateTime @DateTo, SqlInt32 @PriorityTime, SqlDecimal @AdjustmentTime, SqlDecimal @Status)

{

SLARemaining.CalculateTimeRemaining remaining;

remaining = new SLARemaining.CalculateTimeRemaining();

int duration = Convert.ToInt32(PriorityTime.ToString());

if (!DateFrom.IsNull)

{

string date = DateFrom.Value.ToShortDateString() + " " + DateFrom.Value.ToShortTimeString();

SqlString result = remaining.GetTimeRemaining(date, duration);

return result;

}

else

{

return null;

}

}

};


The function calls the following method from another class:


public string[] addSupportHours()

{

string[] supportedHours = new string[28];

SqlDataReader dr;



SqlCommand cmd = new SqlCommand();

cmd.CommandText = "xxxxxxx"; //<-- commented out for this post

using (SqlConnection cn = new SqlConnection("context connection=true;"))

{

cn.Open();


dr = cmd.ExecuteReader();



while (dr.Read())

{
//do some stuff
}

cn.Close();

cn.Dispose();
}

The error message claims that the connection has not been initialized - can't work out why? Any help will be appreciated!

The ConnectionString Property Has Not Been Initialized

Jul 30, 2007

In short, I have a couple grid views on a page that are used for editing as well as sorting, etc.  The grids are setup to use the SqlDataSources.  I'm trying to deploy this to a server environment for different instances (test,cert,prod) and am trying to set the ConnectionString for the SqlDataSource in the code behind (Page_Load()).  Everything works well, except, I get an error message that says the "ConnectionString Property Has Not Been Initialized."  Its a javascript alert coming up on top of the grid view.
Here is how I'm trying to set the ConnString in the Page_Load():this.EmployeeTimeCardDataSource.ConnectionString = ConfigurationManager.ConnectionStrings[connStr].ConnectionString;
Here is an example of the DataSource.<asp:SqlDataSource ID="EmployeeTimeCardDataSource" runat="server"    SelectCommand="sp_Select_Managers_Employees_List"    SelectCommandType="StoredProcedure">  <SelectParameters>     <asp:SessionParameter Name="CurrentUser" SessionField="User" Type="String" />  </SelectParameters></asp:SqlDataSource>

The ConnectionString Property Has Not Been Initialized

Jan 25, 2008

Hi all
      This is the code in my web.config file.
       <appSettings>    <add key="ConnectionString" value="server=127.0.0.1;database=testdb;uid=sa;pwd=sa"/>     </appSettings>
      When I'm connecting to the sqlserver database,the page shows that The ConnectionString property has not been initialized.
      The code that I used to get the "ConnectionString" as belows
using System.Configuration;
protected static string connectionString =ConfigurationSettings.AppSettings["ConnectionString"]; 
  public static object GetSingle(string SQLString,params SqlParameter[] cmdParms)  {   using (SqlConnection connection = new SqlConnection(connectionString))   {    using (SqlCommand cmd = new SqlCommand())    {     try     {                              PrepareCommand(cmd, connection, null,SQLString, cmdParms);      object obj = cmd.ExecuteScalar();      cmd.Parameters.Clear();      if((Object.Equals(obj,null))||(Object.Equals(obj,System.DBNull.Value)))      {            return null;      }      else      {       return obj;      }         }     catch(System.Data.SqlClient.SqlException e)     {          throw new Exception(e.Message);     }         }   }  }
 
These code works well on my machine.When running on my colleague's machine ,the page show that exception.
  Any ideal?

ConnectionString Property Has Not Been Initialized

Nov 18, 2005

My IT dept set up an SQL db on a server for me and I am connected to it through a port.  They told me I had to create my tables through an MS Access adp, which I have done.  I am using VWD Express and am trying to create a login page using usernames and pw's from a db table. I am connected (at least the db Explorer tab shows I am) to the MS Access adp and can drop a GridView from my Employees table from it onto a page and get results.  I keep getting the "ConnectionString property not initialized" error message pointing to my sqlConn.Open() statement and cannot figure out why.  I have looked at hundreds of posts but can't seem to find anything that works.  If someone could point me to some post or website that could explain connecting to a SQL db through a port or whatever you think I need to learn to get this fixed I would appreciate it.

The ConnectionString Property Has Not Been Initialized

Feb 5, 2006

I have installed SQL Server 2005 Express Edition.I have defined the connectionstring in my web.config as follows:
<connectionStrings><add name="MyDB" connectionString="Server=local;Provider=SQLOLEDB;Initial Catalog=Shop;Trusted_Connection=Yes;DataSource==.SQLExpress;AttachDBFilename=Data/MyDB.mdf" providerName="System.Data.SqlClient"/></connectionStrings>Here's my vb code:
Dim connStr As String = ConfigurationManager.ConnectionStrings("MyDB").ToString()Dim DBConnection As New SqlConnectionDim SQLCmd As New SqlCommand("SELECT * FROM tblMember WHERE UserName=@UserName", DBConnection)SQLCmd.Parameters.Add(New SqlParameter("@UserName", tbUserName.Text))DBConnection.Open()and on that last line I receive the error: The ConnectionString property has not been initializedNow, I have seen SO many different versions of a connectionstring that im totally confused!!I want to use windows authentication (I know thats better for security reasons).But I have difficulties understanding the attributes required (AND THEIR MEANING!) of the connectionstring. (e.g. do I need to define DataSource or Initial Catalog or AttachDBFileName and the rest? What does it do exactely?)Also: I have registered my server as "MyServer" is that the alias I need/can use in my connectionstring?If someone could explain me the above questions it would be of GREAT help!!

The ConnectionString Property Has Not Been Initialized

Apr 19, 2006

Hello, I have just begun my first web application in vs 2005.  I have a done a bit of coding in VS 2003.  I have some list boxes on the page that use an ObjectDatasource that I set up with the wizard--and they work well and connect to SQL server.  But I wanted to re use some of my old code for another list box on the page and put code in myself. 
  Dim MyConnection As SqlConnection = New SqlConnection(ConfigurationManager.AppSettings("CONN_DATAConv"))
Dim ProcConnection As SqlConnection = New SqlConnection(ConfigurationManager.AppSettings("CONN_DATAConv"))
Dim myCommand As New SqlCommand(CommandText, MyConnection)
MyConnection.Open()
ProcConnection.Open() Here is what is in the web.config   <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<appSettings/>
<connectionStrings>
<add name="DataConvConnectionString_gisad" connectionString="Data Source=PWDGIS4;Initial Catalog=DataConv;Persist Security Info=True;User ID=gisad;Password=erv11new"
providerName="System.Data.SqlClient" />

<add name="CONN_DATAConv" connectionString="Data Source=PWDGIS4;Initial Catalog=DataConv;Persist Security Info=True;User ID=gisad;Password=erv11new"
providerName="System.Data.SqlClient" />
</connectionStrings>
 Please note that I canged the connection string call from
ConfigurationSettingsAppSettings that was in vs 2003
But the connections won't open.  Any help would be greatly appreciated.

ERROR: The ConnectionString Property Has Not Been Initialized.

Apr 17, 2008

Hello,
am trying to run a SP in my class against my database.
However, I get the error below.
The connection string is in the web.config file as thus
<connectionStrings>  <add name="cell_ConnectionString" connectionString="Data Source=xxx.xxx.xxx.xxx,2433;Network Library=DBMSSOCN;Initial Catalog=day;User ID=day;Password=jdhje5rhydgd;" providerName="System.Data.SqlClient"/> </connectionStrings>
and the connection string name is called in my class as thus
 1 SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["cell_ConnectionString"]);
2
3 SqlCommand command = new SqlCommand("cell_ConnectionString", con);
4 command.CommandType = CommandType.StoredProcedure;
5
  
What is wrong here ?
thanks
Ehi

Going Nuts - The ConnectionString Property Has Not Been Initialized - Help!

May 27, 2006

I'm struggling with the different methodologies for using DataSets in 2.0. I can knock this out in no time flat in 1.0, but am bogged down in 2.0. Can anyone guide me on the right track? My code is below. I'm forming a DataSet from a SQL Server Express database from the user's choice from a drop down. My connection string "ASOCTCOConnectionString" is declared in my web.config and used successfully throughout in the WYSIWYG configurations of my databound controls.  But I want to control this in code. This si getting frustrating and right now I'm longing for the clean simplicity I had with Web Matrix :(
In any case, any suggestions? It crashes with this error when opening the connection with MyConn.Open(). I just want to be able to configure a DataSet and apply it to my controls and results.
<code>
Dim connectionString As String = System.Configuration.ConfigurationManager.AppSettings("ASOCTCOConnectionString")
Dim MyConn As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim MyQuery, SearchString As String

Dim myAdapter As New System.Data.SqlClient.SqlDataAdapter
Dim myDataSet As New System.Data.DataSet
Dim mySelectCommand As New System.Data.SqlClient.SqlCommand
mySelectCommand.CommandText = "SELECT * from Device_Type where Category LIKE " & DDLDevType.SelectedItem.Text
mySelectCommand.Connection = MyConn
MyConn.Open()
Grid1.DataSource = myDataSet
Grid1.Databind()
MyConn.Close()
</code>

Cannot Set Connection Property Of Backup Database Task If Connection String Is Customized In Connection Object

Aug 23, 2006

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.

Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.

Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.

Is this an intrinsic issue?

What Is The Property-ID For Local Connection String

Jan 30, 2007



I'm using the SQLCE 3.0 OLEDB Provider via VC++. I cannot seem to find any C++ documentation on using the Local Connection String. We need it to set the Max DB Size.

My primary question is what is the Property-ID for Local Connection String?

Connection Manager Property Expression Editor

May 16, 2007

Is it possible to use a property, say name, of an object ( say the connection object) in the "Property Expression" of that object? I would like to modify the Connection String property of a flat file connection manager to append date to it. To do this I need to be able to use the Name property of the connection manager in the Property Expression editor. How ever I get an error that it does not recognize name, it almost seems to suggest I can only use variables. I find it hard to believe since it seems like common requirement to be able to use properties of an object (connection manager) in modifying other properties of the object. Any help would be greatly appreciated.
Thanks.

Changing The ConnectionString Property For A File Connection Manager

Mar 14, 2006

I have a package that I plan to run against about 700 databases to look for anomalies. I have several package variables in place that are passed in at runtime. One of them will hold the path and filename of the error log for the current database in process. I want each database to generate it's own error log for documentation and research purposes. However, when I run the package, it continues to use the path and filename that I entered when I created the File Connection Manager. I am trying to update that value in a Script Task by using the ConnectionManager class and setting the value for the "ConnectionString" property. This method is working for the OLEDB Connection Manager (which tells the package which Access database to process), but not for my File Connection Manager. Please help!

DTEXEC.EXE /SQL "ProcessReportingDatabase" /SERVER RTG23SQLDB01 /REPORTING V /SET "Package.Variables[User::RunID].Value";35 /SET "Package.Connections[RSAnalytics].Properties[InitialCatalog]";"Fnd Prj 1 Dec29" /SET "Package.Connections[RSAnalytics].Properties[ServerName]";"RTG23SQLDB01UAT1PROD"

The problem does not happen with the [User::RunID] variable or the [Initial Catalog] property of my [RSAnalytics] connection object. But I am not successful in setting the [ServerName] property.

What happens when executed is that the package retains the ServerName property of the deployed package (Value="RTG23SQLDB01UAT1QA"), instead of what I pass in via DTEXEC???

Is ServerName read-only or something? I've tried configuring the package connection to RTG23SQLDB01UAT1PROD and creating a package configuration that I specify in place of the /SET - but to no avail as well!

This package has to work against 10 instances. I really don't want to have to create a separate package for each instance, and then a hack to figure out which one to call.

TIA - Dave

Problem Configuring Password Property For Oledb Connection.

Feb 17, 2006

I'm creating an xml configuration file to hold the connection string including the password (sql server authentication).  My package protection level is set to 'EncryptSensitiveWithPassword'.  I set up my connection manager and I check the 'Save my password' box. The  'Test connection' button reports that the connection is OK.  I enable the package configurations and I go through the Package Configuration Wizard and I specify 'xml configuration file' and I choose 'Specify configurations settings directly' and I specify a configuration file name with the same directory as the package.  I check the 'ConnectionString' property and the 'Password' property and then click 'Close'.  Then I save my package changes.  Now I look at the xml configuration file in a text editor and I see the Password property has an empty element:

<ConfiguredValue></ConfiguredValue>

Is it supposed to be empty?  When I right-click the package in solution explorer and pick 'Reload with upgrade' then I have to enter the password, but the validation fails with 'Acquire connection' error.  Should I just be saving the 'Connection string' property, or should I save all the connection elements (i.e. ServerName, UserName, Password etc.)?  If I edit the xml configuration file and I type the password into the <ConfiguredValue> element above, and then I do 'Reload with upgrade', then the 'Acquire connection' validation error goes away.  Could this mean that I am not able to encrypt the password?  Thanks.

Integration Services :: SSIS - Connection Manager Property Not Set From Project Parameter

Oct 2, 2015

I am working with SQL Server 2012. I have deployed a SSIS project that has 2 packages in it. The package connection manager (Test) uses an expression to evaluate one of the Project parameter value (TestConnectionString) to set its ConnectionString property.

This works fine in a Dev environment. However when deployed to UAT, it keeps failing with the error: 

PackageExport:Error: The result of the expression
"@[$Project::TestConnectionString]" on property
"Package.Connections[Test].Properties
[ConnectionString]" cannot be written to the property. The expression was evaluated, but cannot be set on the
property.

I can not seem to find what the issue could be. I have come across [URL] .... where it says: "If the package contains project parameters, the package execution may fail." but offers no solution.

Changing Header Rows To Skip Property In Flat File Connection During Runtime

Dec 21, 2006

Hi all

I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.

My expression is as follows:

DataRowsToSkip : @[user:: Var]

where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.

I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.

Its not working....

Can anyone help me out in solving this????

Thanks in advance

Regards

Changing Code Page Property Using Property Expression Doesn't Work

Jun 16, 2006

I am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.

But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.

[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.

If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.

Can someone please help me resolve this.

Thanks much.

Value Of A Readonly Property Of Custom Task Is Not Updated In Property Window

Apr 17, 2008

Hi,

I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?

Thanks for any hints.

(URGENT) Cannot Be Written To The Property. The Expression Was Evaluated, But Cannot Be Set On The Property

May 7, 2008

Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing
"OnError,,,,,,,The result of the expression

"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere"
" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."

I have child SSIS package running under a parent package (through execute package task)

I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager.
The Expression is as follows



"@[User:trTextFileImpDirectory] +"SomeTextStringHere."+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ +"SomeTextStringHere"

Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text
files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch
value from a configuration file on local server.

With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)

While
"Some string here"+ @[User:trANTTextFileName]" part of file name string.

(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.

1) So can someone give me some insight into possible reason of failures.
2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ?
3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?
