Application That Measure Response And Loading Time Of Webpage
Sep 6, 2009
I like to make an console application to measure the time it takes to fully load a web page, what's the best approach to do that? The purpose of this small app is to monitor some pages in a website, in a predetermined interval, in order to be able to know beforehand if something is going wrong with the webserver or the database server. It would be nice to be able to measure the time it takes to fully load the the page (images, css, javascript, etc). I have some code but I is not measuring the fully page.
Dim sw As New System.Diagnostics.Stopwatch
Dim req As System.Net.HttpWebRequest = CType(HttpWebRequest.Create("[URL]"), HttpWebRequest)
sw.Start()
Dim res As System.Net.HttpWebResponse = CType(req.GetResponse(), HttpWebResponse)
sw.Stop()
Dim timeToLoad As TimeSpan = sw.Elapsed
I need a start date, a Total time passed until now, an average time per step, and a estimated time to finished. How can I do that? Also, I can close the application and when start up again I want to get the time counters as the last time, so How can I store that data is normal txt file (I say txt to take advantage of the ini app file which is a txt).
I have a VB.NET application that executes a test when the user clicks a "Start" button. The application communicates back and forth with a USB device and eventually stops when the USB device sends back a specific trigger, or if the user chooses to cancel the test. I would like to measure the time elapsed during each test and display it to the screen.The program is significantly complex and I have several timers that control sampling rate, the frequency of the output, the frequency of signals in a calibration method, etc.I tried two approaches so far, both of which led to invalid time measurements. I say they're invalid because I used several stopwatches I know to be accurate in addition to the system clock (the clock with a second hand that pops up when you double click the time in the bottom right hand corner of Windows XP) to measure the actual time of each test. Consistently, my program will indicate more time has passed than actually has.I tried simply dividing the number of samples I took by the the sampling frequency. I got back a time that was about 1.33 times greater than the actual time. This ratio would change with different frequencies, and even with the same frequency from day to day.
I tried using the DateTimePicker in my main form to measure the time passage. At the start of the test I'd record the start time, startTime = DateAndTimePicker1.value, at the end of the test I'd record the end time, endTime = DateAndTimePicker1.value, and then I'd set the text of a label equal to their difference, TestDurationLabel.text = (endTime - startTime).ToString. I initialized startTime and endTime as Dates. I get back a time that is about 1.2 times greater than the actual time.
I made two applications the first one calls the other. But the other application takes time to load. Even on a fast Pc. So i was thinking of adding a loading form to it. For example when the other application is done loading the loading form goes away.
Above is the response of the page I am trying to get if I enter the URL: However, the program just crashes with the following code (i.e. never even displays final - meaning stream is still going on) I think that it is streaming the video, in addition to the source- which I do not want to happen How can I retrieve this source?
I have a question. I am creating a VB .NET application that opens Visio to do some stuff there. Visio runs a splash screen on startup and the only way to stop the splash screen from loading is to use code like:
Basically, I have a Web Browser object on a Visual Basic form. However, about 5 seconds after it finishes loading ANY webpage, the entire program stops responding. I figured the issue was related to internet explorer, so I updated to Internet Explorer 9 Beta and the issue is fixed (this is a very strange fix)!!! However, Internet Explorer 9 is not available for Windows XP. what might be causing this and a possible solution for computers that are running XP?
I'm not able to find my answer from threads.I want close the loading of web page when it take more of tot seconds...(if is possible with a Firefox or IE)
StrAdrress = "http://www.google.com" Try System.Diagnostics.Process.Start(strAddress.Trim) Catch ex As Exception MsgBox(ex.Message, MsgBoxStyle.Critical, "Error") End Try
Threading.Thread.Sleep(50000) So you can see I wait 50 seconds now..Is it possible to convert this code in : if the page not load in 10 seconds, stop load,close the tab and open another tab with another address?

how to get my program to submit user data into a login form and then wait until the next page is done loading so that it can examine the contents of the page and determine whether the login succeeded or failed. Here's my current code:
Public Class Dialog1 Private Sub Dialog1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I'm trying to login to a website wait for the page to finish loading then navigate to a page in this website.

How to use the documentcompleted?
I'm trying to see if a file I have loaded is located in the "Xampp-localhost-folder".
I'm loading a php-file-path into a textbox. After pressing a button the php file is loaded in a webbrowser. Now here's a problem. .PHP-files don't load local. The user needs to have at least Apache (MySQL/PHP/FileZilla FTP Server etc) installed so the page can be loaded via localhost.
The most important service that needs to be running is httpd.exe (Apache) or FileZillaServer.exe.
Public Function ProcessesRunning(ByVal ProcessName As String) As Integer Try Return Process.GetProcessesByName(ProcessName).GetUpperBound(0) + 1
I have a windows service that utilizes an infinite loop and thread.sleep. The sleep time for the thread is 10 seconds.When the service is initially started AND has work to do (data exist in SQL), it immediately does it's processes. It continues to be responsive and process tasks every 10 seconds as long as it has work to do. If no data is present in SQL for an extended period (i.e. 15-20 minutes) then the service starts responding very slowly. It will eventually pick the data up and process it, but it takes more like 10 minutes instead of 10 seconds.
How can I stop users from clicking into a webbrowser until the webpage has completely finished loading ?Until the webbrowser DocumentCompleted event has completed users should be able to see the page but not click into the control.

I have created a vb.net application that uses a SQL Server database at a remote location over the internet.There are 10 vb.net clients that are working on the same time.The problem is in the delay time that happens when inserting a new row or retrieving rows from the database, the form appears to be freezing for a while when it deals with the database, I don't want to use a background worker to overcome the freeze problem.I want to eliminate that delay time and decrease it as much as possible?
I was currently writting a Cyber Cafe for the client side which start up with a form that maximize and block all the client control like shortcut key and other security. It's fine to work in my pc and it take only about 5 second to startup the application and lock the client. But when i run the application in a pc that installed with games, it took about 40 second to run my apllication. I notice in task manager panel, the process need to read the whole application before it could load my first form. Is there any idea i can speed up my loading time? I have try to set the process priority to "real time" and startup using batch files, but it still need 30 second to load my first form.
I am going to open word document inside the browser.

Me and a few other people are developing a piece of software that measures levels of distraction based on some user settings. The user will be able to designate certain programs, websites, etc. as "on task" and anything else will be considered "off task" by the program. The only road block we have run into is being able to grab the user's current web page in real time -- at any given second we need to be able to programatically determine what web page the user is viewing (in any browser) and determine whether it falls under "on task" or "off task". We would like to do this by creating a C# extension for Fiddler2 but are open to other suggestions as well (the software itself is programmed in VB.NET).
I am using stored procedures in my application using vb.net, while executing stored procedures on mysql database server thru application, the response time from the server is more. Is there any settings that i need to set on mysql db server or any changes in connection string or in code.
