Simulate Records In Database Without Entering?
Mar 2, 2010
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)?

I am a beginner with ASP.Net and I am trying to build a Web site which searches a MS SQL database for a person by name using a search form. I have decided to do this project in two steps. Step one was to develop the functionality in basic .aspx page, and then step two is to transfer the working code into the 'business starter kit' template provided with Visual Studio Express 2008. During step 1, I have created the search form, a results page, and also a detailed results page which all work exactly as desired. However, I have now been working on step 2 and trying to place the search form portion of generic page into a page created within the actual web site created using the business starter kit and this is where i am running into problems.
My search form will not work and gives me no results when I enter in a person's name. I have checked, double-checked, and qtriple checked all of the controls I am using, the database connection, the gridview settings, etc... and everything appears correct. I can create simple .aspx pages, not utilizing the masterpage.master file, and copy and paste my search from code into that and again everything works perfectly, but it does not work within my actual Web page being used for the site. Thus, this leaves me to believe the probelm has something to do with the masterpage.master page. Can someone take a look at my code and see if they see anything which may be causing my problem(s)? I have been working on this since sunrise this morning and it is getting quite frustrating that I cannot figure out what the problem is.
search.aspx page code

masterpage.master page code

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 am working on a project in .NET (C#), connected with a database. And I am entering values in database through 'text-box' control, for a part of the project. What I want is to check if the user entering value already exsists in the database and if so, shows error during that time only.
I have searched for any familiar post here, that could solve my query, but didn't get any.
my EXACT objective(if not cleared earlier):-
when the user enter the value in
textbox, automatically an event to
check any duplicate records in
database should occur. And if found,
displays an error message

currently 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.

This is my GET Method to get my data from my DataTable
Private Function GetData() As PagedDataSource
' Declarations
Dim dt As New DataTable
Dim dr As DataRow
Dim pg As New PagedDataSource
' Add some columns
dt.Columns.Add("Column1")
dt.Columns.Add("Column2")
' Add some test data
For i As Integer = 0 To 10
dr = dt.NewRow
dr("Column1") = i
dr("Column2") = "Some Text " & (i * 5)
dt.Rows.Add(dr)
Next
' Add a DataView from the DataTable to the PagedDataSource
pg.DataSource = dt.DefaultView
' Return the DataTable
Return pg
End Function
It returns the DataTable as "pg"
What changes must I make to this GET method to get the records from a table in my database?
C# examples will also do but would be great to see a reply with my code and then the changes....

On an ASPX.Page, I have a button that performs a postback. User must be prevented from clicking it more than once. I want to do this with jQuery but
jQuery(document).ready(function() {
$('#<%= saveButton.ClientID %>').click(function() { $(this).attr('disabled', 'true'); });
});
doesn´t work for me because the button does not postback. Is there an easy way to prevent a second click while still keeping the functionality of the button?
