Recent we are deploy(Setup and Deploy) our Product which is develop in ASp.Net(C#) using SqlServer Here We Face one Problem i.e.
When we install the porduct there is no issue if we manually run the sqlScript file in sql server(manully we create the DataBase and All DataBase Object i.e. Table,StoreProcedure,Function,Views....& We are enter the Sample Data) But We know that is not the Right Approch.
Any one Can tell me the procedure "How to Building DataBase & All DataBase Object with Sample Data when we click the Install and set up file"
In Setup and Deploy wized it ask for any Dependence file for the application i have attach the Dependence file(.sql) but i am not getting any OutPut .
Is there any Command prompt Utility(SqlServer/VS Commandprompt) ?
I know this is kind of simple in my head but the logic has been driving me nuts going through it. I'm trying to build a string from 2 list boxes. Once they select an item in the first list box (that's pulling the list items dynamically from a database), then the second list box appears. Once they select the second list box the video player below it displays a flash video that they chose based on which camera and the date/time of that particular camera. The path for the flash video (.flv) is in the database. I get everything to work up to displaying the flv player but it doesn't play the video since the path to the flv isn't there. Here is the code I currently have along with the queries.

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?
I have a CheckBoxList that I need to get the values from, concatenate, and pass into a stored procedure in SQL Server 2005 utilizing Visual Basic. Due to the way our data layer is I cannot use a SqlCommand object at this level.
I have no problem getting to the selected values in the CheckBoxList:
Dim selectedValue As New StringBuilder
For i = 0 To cblMethods.Items.Count -1
If cblMethods.Items(i).Selected Then
selectedValue.Append(cblMethods.Items(i).Text)
End If
Next
The problem is that I do not know how to list the values in such a way that my stored procedure will pull data:
SET @MethodNames ='GetWords','GetLetters'
SELECT * FROM TABLE WHERE method IN ( @MethodNames )
I've tried experimenting with apostraphes but cannot make it work:
selectedValue.Append("'''" + cblMethods.Items(i).Text + "''', "
I am looking to build a web application from the ground up. I have done a bit of research, however I just thought I would post here to see what kind of responses I get. I will give a brief description of the type of application I am trying to build. It will be a database web app for managing clients and financials of those clients. The application will need a secure log on system for approximately 160 end users, with the ability to change permissions for each user given their individual rights.
Depending on the type of user created they will have access to 1 of 7 unique application modules within the app framework. A data dictionary will be designed and created prior to starting the project as the 7 unique application modules will have common database fields and custom relationships. Based on this information, what asp.net tools, libraries or books would you recommend using?

I am in the process of creating a forum design from scratch, as my first official asp.net application attempt.
Overview:
I would like to handle this task in the following steps:
1) Get input from the user: txtLoginEmail, txtPassword
Form has been submitted:
2) Process inputs a) cut/trim white spaces
b) encrypt password by using SHA1 hashing method located in clsLibrary
3) Check the email address given against the database
Match: Display a message saying that the username already exists.
Doesn't: Add the email address and add encrypted password into the database
Question:
In my Register.aspx.vb code-behind file, inside of the question mark lines, how exactly do I check against
the database to see if that user exists in that database already? I thought perhaps storing the results in
an array and then looping through it to look for matches, but that sounds inefficient. I tried this idea
and after an hour I was unsuccessful. Below is my code for the class objects and pieces of code relevant to this task:

I am inserting the records in Database thru asp.net??One of the columns is unique, I want that suppose the user inserted the same value once,control goes to catch block, I wnat to show my own error message ,only if unique index is same ,Rest for the other exceptions,it thrown by .Net?/
View 11 Repliescurrently I am doing an online store project using an example from one of your tutorials. In the grid view is populated with data and at the below of the grid view, there is a row of empty fields populated below. After user have enter all the necessary info and clicks on the Add New link, the data will be inserted into the database and it will also be displayed in the grid view itself. The software that I am using is called: MS VS 2008 C# The database that I am using is called: MS SQL Server 2008 This is the database.cs for inserting records into the database:
Code:
public bool Insert_ItemsRecords(string id, string itemName, string itemDesc)
{
SqlCommand cmd_ItemsList = new SqlCommand();
cmd_ItemsList.CommandText = "[VRM].[INSERT_ItemsRecords]";
cmd_ItemsList.CommandType = CommandType.StoredProcedure;
cmd_ItemsList.Parameters.Clear();
SqlParameter sqlParaID = new SqlParameter("@id", SqlDbType.VarChar, 10);
sqlParaID.Value = id;
cmd_ItemsList.Parameters.Add(sqlParaID);
SqlParameter sqlParaItemName = new SqlParameter("@itemName", SqlDbType.VarChar, 100);
sqlParaItemName.Value = itemName;
cmd_ItemsList.Parameters.Add(sqlParaItemName);
SqlParameter sqlParaItemDesc = new SqlParameter("@itemDesc", SqlDbType.VarChar, 1000);
sqlParaItemDesc.Value = itemDesc;
cmd_ItemsList.Parameters.Add(sqlParaItemDesc);
return executeNotQuery(cmd_ItemsList);
}
This is the stored procedure:
Code:
ALTER PROCEDURE [OS].[INSERT_ItemsRecords]
@id varchar(10),
@itemName varchar(100),
@itemDesc varchar(1000) .................
I have the code below which does work, but I need to add further functionality to it. The functionality I want to add to it is the text I have commented in the code below.
Dim objSQLConnection As SqlConnection
Dim objSQLCommand As SqlCommand
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim intID As Integer = CType(Request.Form("ID"), Integer)
Dim strHeading As String = CType(Request.Form("Heading"), String)....
Before the if statement, I want to find out if the database already has records with the username in the strUser variable.
I have an ASP.NET web form application that on the server side I need to know the user's identity. I do not need to impersonate the user. I just need their username so I can update some records in a database correctly.When the request is processed I have the following line of code:
string userName = Request.LogonUserIdentity.Name;
if(true == string.IsNullOrEmpty(userName))
{
logger.logwarning("missing username");
}
else
{
logger.loginfo("update by {0}", userName);
}
In my development & QA environment this works perfectly - I see the userName in the log file and all of the database records have the lastModifiedBy field filled in correctly. However, when we go to production - userName is an empty string.
i want to add the particular field in dropdownlist by coding so hows that's possible

I have a datatable with some records.
i want that if record id is exists in database then update the record otherwise insert the record.
But i don't want to hit database again and again, i want to accomplish the task on a single hit.
I've nearly finished the development of a project and would like to test its performance, especially the database query calls. I'm using Linq to SQL to search via usernames, but I've only got around 10 'users' in my database, so I can't really get a decent speed reading. How can I simulate thousands/millions of users in the database without actually creating new records? I've read about Selenium, but it seems that is good for repeat actions (simulating concurrent users?). Are there any other tools I should look into, or are there any options in VS 2008 (Professional Edition)?

View 8 RepliesI have 2 tables in SqlServer 2008.
Table1: T1id, SomeData
Table2: T2id, T1id, SomeData
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".
I have in my page an edit button and textboxes. I want to edit one single record from the database to these textboxes.
