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.

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:
"C:Program FilesMicrosoft OfficeVisio10Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio11Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio12Visio.exe" /nologo
For each Visio versions in the command line (but I am not using the command line).
The problem I am having is that I can't run this code from my vb .net application, because my application uses the following code to load Visio:
Dim vsoApplication As Application
vsoApplication = New Visio.Application()
vsoApplication.Visible = False
And I do not know how to call the "/nologo" feature on loading time from my code to skip the Visio splash screen.

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)

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?

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.

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.

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 have been working on a project of mine that will streamline some issues at the office. (Note: There is not much in way of documentation or comments as I just started on this)
This is what I have so far and I am getting this error:
"System.ObjectDisposedException was unhandled"
I can edit the database with the second form initally, but it pops up an error after I return to Form1 and then attempt to enter into the 2nd form any subsequent time after the first initial load.
Here is my code:
Option Strict On
Option Explicit On
