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 RepliesI am trying to check how much time does a function takes to execute in my code :
I did this :
void foo()
{
int time = System.DateTime.Now.Millisecond;
// code of my function. do this, that, etc.
Console.WriteLine((System.DateTime.Now.Millisecond-time).ToString());
}
What i get is this :
-247
I don't understand why minus ?? & If pro-filer is an option then recommend me some simple option.
Note : Here I have shown a console app but in practice i need for a Web App in ASP.NET which may be n-tier architecture also.
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.
Is it possible to measure the elapsed time from when a user clicks an 'ajaxified' button until the ajax controls are updated?
I'm using ASP.Net v4, Visual Studio 2010, C#, and the MS AjaxToolkit.
I am writing a program to measure the latency(response round trip time) for a web service. I need to have this at client side.
My initial plan is to store the time at which request is sent and then calculate the difference in time when we recieve a response from the web service. Is this the correct way to measure latency of web service. This has some overhead because of storing time and all. How can this be done?
Another option is to attach a timestamp with the SOAP request. But the server should return the timestamp. This will not be possible in case of third party web services.

View 9 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?
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?
internet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.
The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.
Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.
good way to upload multiple files at the same time? I currently am able to upload one file at a time, but would like to be able to select them all and then upload. Right now i am using asp: FileUpload control to upload the files, I know I could just use several of these and then loop them in the code behind to upload, but the pages I am working on have different amount of images to upload.
I have worked on 2 so far, and the first page I had to upload 12 items, while the second page I had 9 to upload. So i don't want to have a ton of these on the screen. Is there anyway i could use a ListBox or something to load them all in the listbox then loop through the box? I would prefer to have a listbox or textbox even, then have like 12 FileUpload's on the page.

need ASP.NET File Upload with Real-Time Progress Bar
View 13 RepliesI made a website for a friend and he uploads a lot of pictures, around 20k per month. And sadly, I made it so he has to upload 1 at a time, because when they are uploaded they are renamed, attached to a group id and watermarked. Is there a way to allow him to select all 20 in a group and have them be uploaded and processed? I've looked into a couple of way to do it, mostly flash, and that will not work since we are renaming and added the newly created name to the db. Adding addition upload controls is not a solution. If we need to make a desktop application that does the uploading, that is alright as well, but we'd like to keep it all in the asp.net environment.

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 want to be able to run an ASP.NET application when a file is upload via FTP. I understand how to use the filewatcher class to monitor the directory but I don't know where to put the code so it is always running.
Files will be uploaded once per month for each group of users of the system and the next time the user logs on after the upload I would like the application to reflect the new data. I don't want to check for a new upload when each user logs on because the processing could take a log time.
The uploads are automatic from multiple other computer systems and not done by any user.
The Application is hosted (by GoDaddy) so I don't have full control of the server.
Is there any way to have a process running all the time in the background and if so how? The application is written in VB.net.
Is there any control out there that will allow a user to upload multiple files at a time to a web server?
View 3 RepliesIs there simply no way to grab multiple files and upload them at the same time via a webform? I have searched everywhere and I cannot find a single code example. The best that I can find is selecting one file at a time to a listbox for holding and then uploading. This is NOT going to work for me.
