Dear all,
I'm using ASP.net 2003, I need to display some of the messages that retrieve from a table in my sql server 2k. When I run the program, it works fine, but all of the messages that are supposed to get from the db table were not show. Below is my connection string in web config :
<add key="dbconn" value="data source=localhost;initial catalog=MyWeb;Min Pool Size=3;Max Pool Size=20;Pooling=true;password=mypassword;persist security info=True;user id=sa;workstation id=local" />
Any help will be greatly appreciated

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,

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,

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!

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?

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>

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?

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. Web config:

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!!

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.

}
public MovieDataReader()
{
SqlConnection con = new SqlConnection(@"Data Source=""ANDREW_JRSQLEXPRESS"";Integrated Security=True;Initial Catalog=Movies");

try
{

cmd.ExecuteNonQuery();
}
finally

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

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>

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?

i defined 3 pkg scope user variables of type string in the ssis variables window, typed null as their value, and tried passing them (thru exec sql task) to an sp who expects 3 varchar(23) params.
The sp is blowing up because their values arent null.
The sql task command reads exec sp_name ?,?,?. In the sql task editor's param mapping window, I have each param listed with direction "input", data type varchar and the individual sp params in the parameter name column. I think the plumbing is set up correctly because I'm fine when I send the System Variable StartTime as a 4th param to the sp with data type DATE on the ssis end and datetime on the sp end.
Does anyone know if ssis string and engine varchar are incompatible or perhaps if null in the variables window doesnt initialize variables?

Where is SQL storing and caching the assemblies used by CLR SP?
I want to read a mapped configuration file for that assembly but it seems that assemblies are not read form their initial location.
Is there a way to use configuration files for the assemblies used by CLR SPs? (I don't want to use a static string to point to a file on the disk)

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.

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!

I am launching a package the following way:
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

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.

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.

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
Suganya
