Get Accurate Amount Uploaded With TCPClient
Jan 3, 2011
I'm using the code below to send large strings (500kB) to a server. I'd like to show the upload speed and in order to do that, I need to calculate the amount uploaded every second.
In a Timer that fires every second I get the BytesUploaded, divide it by 1024 in order to get KiloBytes (kB/s) and show it to the user. Then I set BytesUploaded to 0 and one second later do the same process.
The uploading is done asynchronously and the size of the data is added to BytesUploaded at once. This means that BytesUploaded is not being updated in a constant flow and has a totally different value almost every second.
0
512000

I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)
but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

im trying to make a simple program that calculates the time it takes to cover x amount off nautical miles at x amount off knots, the code i have so far is this :
Code:Public Class Form1 Private Sub Label2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label2.Click
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
[Code]...
so if i say want to cruise 29 miles at 12 knts it gives me an awnser of 2 hours 24.6 mins instead of 2 hours 25. Although i do realise that 2 hrs 24.6 is technicaly right i was wondering if anyone here could help me with getting it into the correct format?

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

Every sample code I've ever found for drawing rounded rectangles using GDI+ goes something like this (lifted and slightly modified from BobPowell.net):
Private Sub Panel1_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles Panel1.Paint
e.Graphics.Clear(SystemColors.Window)
e.Graphics.SmoothingMode = SmoothingMode.None
[code]....
This produces a rounded rectangle where only the top left corner is accurate.AntiAliasing has to be turned off because it is going through a remote desktop connection, and I can't depend on it being available. Besides, I am looking for a crisp rounded rectangle.I've tried resizing the other corners and changing the pen alignments, but nothing seems to produce a simple, accurate rounded rectangle.Is there a way to draw a better rounded rectangle than this in good old winforms?

I am currently using Decimal, thus far I have not checked thoroughly if it will have any inaccuracies so I wish to know from your experiences what is the best variable type for calculations, it would mainly be for areas.

look at this class and say why it's just returning just the first row in the second query, the issue is that the Salary is showing the right value when debugging, but when deployed to IIS it's just returning the 1st row

I'm creating a program (SURPRISE!), one of the features it has is a tutorial helping with learning a language which has a lot to do with the program's topic. So, I want the program to be capable of getting what the user inputs using his microphone (as a respond to a question the program asks), then analyze it and compare it to a prerecorded answer, then tell him how well he did. How to do that?
If this can't be done using VB.Net, which wouldn't be much of a surprise, then what programming language or whatever do you recommend for me to create an external .exe file which takes in the input, analyzes it, and returns the result to my program? (Isn't this the longest sentence in the English language!)Yeah, and, how can I control how accurate the program is while comparing them?

I am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.

is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?

I need a snippet to check file for validity (I'm allowing users to upload xml files). So I need to check whether uploaded file is XML. The best I can think of is just check if extension is ".xml". What if its replaced?

If you were to upload a project to any site but are concerned about the large file size, what are the only files you need to zip up for your project to work for either VB 2008 or VB 2010? So far I know you don't need the exe's, the pdbs, and xml files.

I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse

I'd like to get both C# and VB.NET sugestion.
I have an ASP.NET FileUpload control, which allows only image type. I used RegularExpressionValidator like below.
<asp:FileUpload ID="fuPhoto" runat="server" TabIndex="40" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator3"
runat="server" ControlToValidate="fuPhoto" Display="Dynamic"
[Code]....
This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.
How do I examine the file content being uploaded?
