I have a TCP connection set up and I know how much data is coming in etc. I was wondering if there was a direct way to measure the current bit rate or a best practice to measure it accurately, say over a couple of seconds?
View 2 RepliesWell an alternative way is by just showing the connection speed which is:
Dim AllNetConn() As NetworkInterface = NetworkInterface.GetAllNetworkInterfaces
Dim IntConnSpeed As Integer = AllNetConn(0).Speed / 1024
Dim StrConnSpeed As String = IntConnSpeed & " Kbps"
[Code]....
But i need something more specific like the download/upload speed.. I know that i could make my program download a file with the size of 100kb and measure how much time it took to download but i dont know how to measure the time...
You know in windows, it says your connection speed down in the toolbar. How can I find this programmaticaly in vb.net?
Here is my code to get internet connectivity

I am writing a VB.NET app that connects to a legacy application using TCP.
The communication is working fine and is very quick once connected, but there is always a delay (of around 2.5-3.5 seconds) when I create the new connection even though I am connecting to my local machine[code]...

View 4 RepliesI have some problems that about GraphicsPath:
How to measure a path's length?
How to insert a point along the path without changing its pattern?
and how to get a nearest point along the path with a given point?
or
get a on-path-point with a given percentage of the length of the path,
e.g.: 3/4 of Path(new point(){(0,0),(2,4)}) = (1.5,3)
(like Adobe Flash, the object can follow a path to move.)
I have tried to measure length with Graphicspath.flatten, but it takes time and not accurate enough. Is there a formula to do that?
get sample code by using NI-6009 to measure voltage(Vrms) and Curent (Irms) . Before this i'm trying to make code with using example in National Instrument VB2010.But i still can't display the right values of voltage(Vrms) and Current (Irms) from waveform that I used.The data comes from data acquisition grid in source array i used to plot sinus waveform.But the problem is I don't know how to measure voltage(Vrms) and Curent (Irms) from that waveform. I am also don't know how to start programming between NI-6009 DAQ Card and Visual Basic 2010 Express.
View 1 RepliesI 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.
As I've noted in another thread I'm trying to put together a secured kiosk app for access to our college library catalogue.I've managed to do most of the stuff with little fuss but, given that I'm not much of a programmer, I'm having a bit of trouble with certain features I'd like to incorporate.One of them is that I'd like the webbrowser control to return to the components designated homepage after 5 minutes of inactivity.

The problem I'm having is while trying to find all Measure Groups that are related to a given Dimension. I've been digging through the API and it doesn't seem that Dimensions have any information on Measure Groups at all, but Measure Groups can contain Dimensions.
This makes it easy if I want to get a list of related Dimensions given a Measure Group(measureGroup.Dimensions), but what I'm looking for is the opposite.
The only thing I can think of is to loop through all the Measure Groups within the Cube and check if it contains a reference to the Dimension in question[code]...

All these method of mesuring the string returns different values for the width, and they are all the wrong value They all mesure the narrow caracteres as "i" as being narrower then they realy are and the wide caractere as "W" as wider than they realy are What would the proper way to draw and/or mesure a string to get the right position on the screen where the text ends
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.
