Does anyone know if it is possible to measure when a file has been downloaded?
I place files for clients to download but there are two things I need to know. One is if the file has been downloaded at all at any point. Second is how many times the file has been downloaded. Can each file (usually but not always image files - sometimes pdfs) be tagged in some way to record what happens to it?
I need to save a file into special folder.
if (TextBox1.Text == s)
{ MessageBoxResult mbr = MessageBox.Show(this, "Do you want to save file?", "saved", MessageBoxButton.YesNoCancel); // if (mbr == MessageBoxResult.Yes) // { // //string path = string.Empty; // string path; // path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "abcFile"; // if (!Directory.Exists(path)) // Directory.CreateDirectory(path); // }
It creates a folder abc if it doen't exist, i need to save s where s is a textfile.
I am building an excel file using the OpenXml sdk 2.0. I am putting it in a memory stream and outputting it to the browser.The problem I am receiving is wiht IE 9 if I click Open it says "filename couldn't be downloaded". If I hit save/save as and save it to the filesystem, then open it, the file opens fine with no errors.
In Firefox regardless of if I use save or open the file when opened in excel says its corrupt.I already built the file by writing it to the filesystem first and that code works. Also since saving to desktop in IE lets me open the file, im assuming the problem has to be with the settings on the Response.BinaryWrite.
I have tried changing the buffer types, changing the content types to include "application/octet-stream", and tried using the extension/content type for office 2003 instead of 2007/2010...Here is my code
Code:
Dim byteArray As Byte()
Using mStream As New MemoryStream
Using spreadSheetDoc As SpreadsheetDocument = SpreadsheetDocument.Create(mStream, SpreadsheetDocumentType.Workbook)
Dim workBPart As WorkbookPart = spreadSheetDoc.AddWorkbookPart
Dim workSPart As WorksheetPart = workBPart.AddNewPart(Of WorksheetPart)()

I am working on a web application and in ASp.Net using VB.net. The requirement is to create a csv file on the server and the user should be able to save the file on his machine. I am creating a csv file on the server and throwing the contents of the csv file to the user using Response.Write method.The problem I am facing is instead the csv file content, user is getting the html code of the page which he is accessing I wrote the following code in my aspx.vb :
strPhysicalPath = Server.MapPath("CSV/" & PathVirtual)
appendFileContents(AppStartupPath, "strPhysicalPath : " & strPhysicalPath)
Dim objFileInfo
As System.IO.FileInfo
objFileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
How can I get the csv content in the file that is being downloaded by the user?

I have a very simple page with which a user uploads a file. Using only server-side C# (e.g. the code-behind), how can I measure the amount of time the user had to wait for the file to upload?
View 3 RepliesIs there a way to measure the time elapsed for a web page to execute?
And if so, is it safe to use that figure to estimate the speed of the web page as the number of users grow and the database grows. Ie: if the page currently takes 1 second to process through x amount of rows in the database, to estimate it would take 2 seconds with 2x rows?
I would like to check how long an ASP.NET page takes to execute (server stuff obviously, not interested in how long it takes to throw the results down the line and for the browser to render them at this stage).
Having done some searching, I came across http:[URL] which shows how to do just this. Trouble is, it doesn't work for me. I copied the code exactly, but the execution time is always zero.
I tried enabling tracing, and that showed an elapsed time between Page_Init and Page_PreRender, but the values returned by Environment.TickCount were exactly the same in both events, so the elapsed time was 9obviously) zero.

I am looking for load testing, to find out how many users my app can handle.
Is there any recommended load testing tool?
how would i go about measuring the number of users connecting a server...
i need to make a code for it..
I am trying to determine if I have a database connection leak. So I need to see the number of open connections. I have some simple test code that creates a leak:
protected void Page_Load(object sender, EventArgs e)
{
for(int i = 0; i < 100; i++)
{
SqlConnection sql = new SqlConnection(@"Data Source=.SQLExpress;UID=sa;PWD=fjg^%kls;Initial Catalog=ABC");
sql.Open();
}
}
Note there is no .Close and this does infact crash after being run 3 times in quick succession.
In order to measure the leak I am running the Performance monitor and measuring SQLServer: General Statistics/User Connections:
However, these seem to be zero when I run my code:
What should I change to actually see the connections?
ANSWER
I have approved an answer below. Even though it doesn't use the performance tools, its good enough for my use. Bottom line is I wanted to see how many connections remain open after opening a web page and this did the trick.
i published an web application now, i want to measure that speed, response time etc., what is the best to find these?
View 4 RepliesI'm making a app for a bank, but it doesnt manage very important data. I have two problems, it will run over a VERY large LAN network protected by all kinds of security(antivirus and firewalls) and the bandwidth in certain regions is as low as 56kbps.(Its a desktop app with a web server backend connected by web services)
From the security point of view all I want is to prevent someone from executing the web services from some other source or app results in change in the database . I'm thinking of each desktop app installed with a install code, this will be hashed and required as a parameter for every function call and will act as an authentication ticket? Is this good enough? Are they better SIMPLER means?
For performance, how do I measure or know if the web service will send and receive data at a decent rate?

I have designed a gridview one of the fields of which I want to send the user to an URL onclick. After browsing the net for a while, I opted for converting the BoundField to a TemplateField. The same OLAP metric ([Measures].[GP]) works fine in the bound field yet produces an error in the Template:

HorizontalAlign="Center"

I have a little web app derived from one template (LinkDirectory). It works fine both on local and on live website.
But, when I download the database (which is filled with valud data, visible in the web app) from the website data (for maintenance purposes), it appear empty (no tables) in my local wite.
What did I miss ? is there a better way to get the database back home ?
