DataSource Controls :: How To Get The Current Identity Number When Doing Insert
May 20, 2010
The scenario is that I wanna insert a record to the database via INSERT query and I need to user the identity number of this record in the INSERT query.
But I don't know how to achieve this.
Here is my table structure and code for your better understanding.
There are three columns in the Table: categoryID, categoryName, categoryPath. I need the path based on the categoryID which is an identity int column.
I have been searching on here for many hours and read many posts but for some reason I am being slow and cannot figure this out. I am writing a record and need to get the identity field back. I have tried many combinations based on what I have read but the below code is where I am sitting at now. it has appdatasource.ExecuteScalar() underlined and the error says 'ExecuteScalar' is not a member of 'System.Web.UI.WebControls.SQLDataSource'. I would be very grateful if someone could point out what I am missing to get this to work.
Protected Sub SubmitApp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitApp.Click
Dim appdatasource As New SqlDataSource appdatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToString appdatasource.InsertCommandType = SqlDataSourceCommandType.Text appdatasource.InsertCommand = "INSERT INTO APPLICATION (FirstName,MiddleName,LastName,AcceptTerms,IPv4Address,DateInserted) VALUES (@FirstName,@MiddleName,@LastName,@IPv4Address,@DateInserted);select @@SCOPE_IDENTITY" appdatasource.InsertParameters.Add("FirstName", fname.Text) appdatasource.InsertParameters.Add("MiddleName", minit.Text) appdatasource.InsertParameters.Add("LastName", lname.Text) appdatasource.InsertParameters.Add("DateInserted", DateTime.Now()) appdatasource.InsertParameters.Add("IPv4Address", Request.UserHostAddress.ToString) Dim appid As Integer = appdatasource.ExecuteScalar() End Sub
How do I set my insert identity return value parameter in codebehind? I have working code now but i have all of my parameters set in codebehindexcept the following:
I am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.
I am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:
USE [iBankRecords] GO /****** Object: StoredProcedure [dbo].[stp_addPayee] Script Date: 07/05/2010 21:57:07 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[stp_addPayee] ( @CUSTID char(10), @PAYEEACCNUM nvarchar(20), @PAYEEACCTYPE char(10) , @PAYEENAME char(20), @PAYERINITIAL char(20), ) AS DECLARE @ReturnValue int INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF) VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF) IF @@ERROR<>0 BEGIN PRINT 'ERROR' SET @ReturnValue=1 RETURN @RETURNVALUE END ELSE BEGIN SET @ReturnValue=0 RETURN @RETURNVALUE END
May I know how do I have generating a unique ref num and inserting the REF into the above statement?
I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables: the number of departments and the number of records in a user control.
Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?
This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.
Cannot insert explicit value for identity column in table 'UserDetails' when IDENTITY_INSERT is set to OFF.
I'm trying to insert a record through a BLL (Business Logic Layer) class with an 'Insert' button attached to the FooterTemplate of a GridView2. My code:
[Code]....
[Code]....
BLL layer code:
[Code]....
The field 'idUser' is autoincremented. When I use SqlDataSource with a DetailsView, add option it adds a record and autoincrements the 'isUser'.
The site is running on my local IIS 6.1. I Would like to add some features to pull information from our AD. My AD code works on many other projects and on my dev server. Here are my attempts at writing out the username:
am writing a web service in vb.net/asp.net 2, that needs user's name. It works fine when the url request is "www.mysite.com" but if any one has logged-in using "mysite.com" without a "www" and goes to the page that calls my web service, The HttpContext.Current.User.Identity.Name gives null. How can I resolve this problem?
I have a web application using Forms authentication provided by AD. I would like to know if it's possible to use EWS to send mail as the currently logged in user without having to supply credentials, or; would I be required to set up an account with impersonating access which will send mail on behalf of the currently logged in user?
So I'm making a asp.net login. I want the login name that people use to match an id in my SQL database. So that I can retrieve their information. But currently when I use the code below, from which I get the name of the computer I am currently on. However I would like the user Identity to be what they write in the username textbox at the login screen.
If HttpContext.Current.User.Identity.IsAuthenticated Then Dim userName As String = HttpContext.Current.User.Identity.Name Response.Write(userName) End If
So I looked for it on net and I think it might have something to do with my web.config file. As I'm totally new to asp.net I wouldn't know. However here's a part of my Web.config file.
I'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.
any one know why are the following two give me different result? they should both give me no results as the value I give is not available. however, number 1 give me many results, and number 2 works as expected. I'd like the number 1 working as the same as number 2.
1. DECLARE

I got this error when I try to browse my default.aspx and I think this problem cause from my web.config. Take a look on my web.config file.

I create two pages, the first one is the login page with user name and password textboxes - (not asp login control) , when clicking login button I check the login authentication, if it is true redirect to default page. in the default page if !IsCallBack then i check httpcontext.current.user.identity.isauthenticated
if it is false i redirect the user to the login page. but my problem is that the httpcontext.current.user.identity.isauthenticated is always false.
I have installed and repaired .NET 4.0 already, and I can not figure out why IIS will not run 4.0 applications. I am running Windows 2003 R2, Sp2. IIS 6.0 I created a new ASP.NET Application in Visual Studio 2010, and published it to a site on my IIS. In IIS, I have selected it to run with 4.0, and my web.config also says to compile in 4.0 My First error was : Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. (C:Inetpub...web.config line 22)
After some research, I found that my IIS had no v4.0 Web Service Extension setup. I thought this was odd, but I manually added it. New error was : The current identity (NT AUTHORITYNETWORK SERVICE) does not have write access to
C:WINDOWSMicrosoft.NETFrameworkv4.0.30319Temporary ASP.NET Files'.
After some research, I found I needed to add this folder, and give all rights to it. I know something is wrong, I shouldn't have to do this. My application is still erroring.. failing to load my ReportViewer :
Exception message: Could not load file or assembly 'Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
My research and I think my aspnet_regiis did not run properly.. so I trieto run this myself: but I get this error!!
-aspnet_regiis.exe - Application Error
-The application failed to initialize properly (0xc0000005). Click on OK to terminate the application.
And a SQL Server database with ASP.NET Membership and Roles. I am using the LoginView control with the AnonymousTemplate and LoggedInTemplate to manage the user's interaction with logging in and out. The problem I am having is that I am authenticating the user against the database:
If Membership.ValidateUser(_userName, _txtLoginPass.Text) Then returns True and: FormsAuthentication.SetAuthCookie(_userName, False) sets the cookie correctly: FormsAuthentication.Decrypt(FormsAuthentication.GetAuthCookie(_userName, False).Values(0)) {System.Web.Security.FormsAuthenticationTicket} CookiePath: "/" Expiration: #1/21/2010 1:42:27 PM# Expired: False IsPersistent: False IssueDate: #1/21/2010 1:22:27 PM# Name: "jaymo " UserData: "" Version: 2 but when I check HttpContext.Current.User.Identity.IsAuthenticated it always returns False. If done this before and it worked fine. I cannot find any mistake I might have made or where something might have changed between ASP.NET 2.0 and 3.5.
We have an SharePoint site no login (anonymous) with a search module using AJAX. Now the users complains that the module isn't working. When I check the code (not developed by me), I find that the code only runs if "HttpContext.Current.User.Identity.IsAuthenticated=true". Could that ever return true on an anonymous site?
i developed a simple web application. A label and a button. On click of Button, the label will display Hello World.
When I deploy this web application on my web server and access the URL, I get this error message.
The current identity (NT Authority/Network Service) does not have write access to C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
I have tried the following -
Navigate to C:WindowsMicrosoft.NETFrameworkv2.0.50727 and typed the following command -
aspnet_regiis -ga "NT AuthorityNetwork Service"
After that also, it did not work.
We checked the permissions of the folder Temporary ASP.NET Files and for the Network Service user, we checked the Security Permissions and it has all the permissions as required.
