ConnectionString Property

Jun 28, 2006

I am having trouble initializing my connection. This is the code:




Dim
DBConnPhone As New
SqlConnection(ConfigurationManager.AppSettings("DBConnPhone"))






        Dim DBConnClient As New
SqlConnection(ConfigurationManager.AppSettings("DBConnClient"))
       




        Dim Sqlcomm1 As New SqlCommand




        Dim Sqlcomm2 As New SqlCommand




        DBConnPhone.Open()




       
DBConnClient.Open()



Once I start debugging, it stops and give me the error "The ConnectionString Property was not initialized" Any suggestions?

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.

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>

Data Access Error - ConnectionString Property

Mar 29, 2006

Hi guys,
I'm getting this error:System.InvalidOperationException: The ConnectionString property has not been initialized
when I'm trying to connect to an SQL database using the following code:
Dim mySelectQuery As String = "SELECT [tabl_id] FROM [myTable]"Dim myConnection As New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("myConnString"))Dim myCommand As New SqlCommand(mySelectQuery, myConnection)myConnection.Open()Dim myReader As SqlDataReadermyReader = myCommand.ExecuteReader()While myReader.Read()   Response.Write(myReader("tabl_id") & "<br/>")End WhilemyConnection.Close()
and in web.config:
<appSettings/>   <connectionStrings>      <add name="myConnString" connectionString="Data Source=100.100.100.100;Initial Catalog=myDatabase;User ID=me;Password=password" providerName="System.Data.SqlClient"/>   </connectionStrings>
If I place the actual connection string inside instead of trying to reference the web.config setting it works, but using 'System.Configuration.ConfigurationManager.AppSettings' returns the error. Is there something I'm doing wrong?

Flat File Source And ConnectionString Property

Sep 11, 2007

Hi,
i have inherited a SSIS project that was left unfinished by a previous developer. One thing i notice with it is that all the flat file sources in the connection manager have hardcoded paths for the ConnectionString property. I would like to change this so that at least the path, and if possible the file name, are dynamic - i.e. they are determined either by parameters passed into the package when it is run or they are contained within a config file.

Is this possible? Can anyone supply a link to an article or tutorial specifically covering this?

Many thanks

Hello!  I'm recieving an error when I submit a form to an Access database.  I took this site over from someone else and kept their code as I'm more of a designer than a programmer.  If anyone has any ideas as to how to fix it, I would really appreciate it.  I'm pretty clueless when it comes to this.  I've tried to figure it out on my own, but I seem to be failing.  Any help would be great!  Here's what I receive when I submit the form:

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!

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)?

What Different Are There Between ConnectionString (Part 1) And ConnectionString (Part 2) In Web.config

Apr 12, 2006

What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config
The CCWW is my PC's name, normally I can connect to the database ASPNETDB.MDF correctly either Part 1 or Part 2 in a web page,After I open Database Explorer panel and browse ASPNETDB.MDF, I can't connect to database using Part 2 when I open a webpage in Microsoft Visual Web Developer 2005 Express Edition,but I can correctly open a webpage using Part 1 after I open Database Explorer panel.
What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config?
I guess  while I use Part 1 to connect, maybe it will be cancel exclusive method of the database  ASPNETDB.MDF first, but when I connect to database using Part 2, maybe two programms both Part 2 and Database Explorer visit ASPNETDB.MDF at the same time!
 
--------------------------------------Part 1------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF"          providerName="System.Data.SqlClient" />  --------------------------------------Part 1------------------------------------------------------------------------
--------------------------------------Part 2------------------------------------------------------------------------<add name="MyConnect"  connectionString="Data Source=CCWWSQLEXPRESS;Initial Catalog=ASPNETDB.MDF;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF"     providerName="System.Data.SqlClient" />--------------------------------------Part 2------------------------------------------------------------------------

Referencing One Item's Hidden Property In Order To Set Another's Hidden Property

Feb 15, 2007

Hello,

I have a group I'll call G4.

The header table row for G4 contains 3 textboxes containing the sums of the contents within G4. The header table row for G4 is visible while it's contents, including the G4 footer table row, is kept invisible until the report user drills down into the group.

When the report user drills down into G4 the footer table row becomes visible and the sums of the contents of the group are displayed for a second time.

At this point I want the sums in the header to be set to invisible when the sums in the footer are made visible by the drilldown.

When I try to reference the hidden property of textbox66 in the G4 footer in order to set the hidden property of header textbox57 in the G4 header I get to this point...

=IIF(reportitems!textbox66.

When it fails to give me an option of choosing the .Hidden property and instead only gives me a .Value.

If I complete the IIF statement manually so that it spells out .....

=IIF(ReportItems!Textbox66.Hidden = False, True, False)

...the report chokes on it.

So my question is, how do I reference the hidden property of one or more textboxes in a group to use as condition checks to set the hidden property of another textbox in that same group?

Thank you for any help you can provide. We are only now beginning to implement reporting services and I have not yet had the chance to research this in greater detail for lack of time.

End Sub  But when it execute i receive this exeption Login timeout expiredAn error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. Is this mean that i can not make a connection to my sql server 2005.
