Sleep For PacketSize/Bandwidth Amount Of Duration For A Network Application In VB?
Sep 20, 2011
I would like to sleep for packetSize/Bandwidth amount of duration for a network application in VB. This value varies from "10^-3 - 10^-6" seconds.When I use the Sleep() func, I think it is not sleeping for the duration if it is less than unity (< 1 sec ~~ 0 sec??).
Edited:I have to keep sending packets after a short nap of above range. So, I could not specify, for eg., to sleep for 0.001 milli seconds at the client side.My requirement is for the client side of CS app, which reads a file and keeps sending small packets at regular or irregular interval of sleeps to the Server. The Server, later, captures the packets and processes it at its own rate..

I have an MDI form in VB.nEt where I have to find, if the application remains idle for 20 mins, I got to log off the logged in user. On doing RnD, I found a class that helps us do the same :- http://blog.perfectapi.com/2008/05/detecting-idle-state-in-winforms-apps/
I saved that class in my applicaiton. In my mdi form's Form Load created an instance of that class. Now I don't know how to move ahead i.e. how to find that 20 min lastActivity duration. I belive I got to trap some evcent in my mdi form and find the value of lastActivity and if that is >= 20, then logoff. But which event to trap and how, I have no clue. In the events for the from also, I didn't found any useful.

Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..

I'm looking for a way to pause my application while in a loop without affecting the users ability to control the application, the sleep thread method makes it seem that the app is frozen.

I'm trying to calculate the amount of CPU usage my application uses.
My code.
Try
Dim CPU As Integer = CDec(PerformanceCounter2.NextValue.ToString)
Label44.Text = CPU & "%"

The problem is that sometimes it says it uses more 115% hmmm.... That's when i was for sure that its lying to me.

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]

There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

I have an application in vb.net that runs over a network. Actually shortcut of the exe file is shared over LAN, so databases remain on one computer where the application has been installed. Everything works great except one thing. The logo of this application is saved in a database, that reports can pick to load picture. The logo file is chosen by the user, using OpenFileDialog and then saved in database. It is saved like D: Picturesfilename. jpg When I run the application from network (using shortcut that we have made to the main exe file), it given error on D:Picturesfilename.jpg because this doe not exits in the system that is running the shortcut. How to save the logo path in a way that it always finds it in application directory, when run over the network.

How difficult would it be to have my application check for user authorization over a network?
If I have a php server, each time someone starts my application it should connect to the server and check the users computer name against a list of authorized computers, possibly using MySQL.
