Is there a way in VS2010 to monitor net usage, and calculate the current/total download and upload while my application is running?
View 9 Replies
I am wanting to create an application that will monitor the upload/download traffic of a user. Can someone point me too some code that I can have a look at?I have found SharpPcap - A Packet Capture Framework for .NET, but cannot find any vb.net code for it.
I have found this code:
Dim Properties As IPGlobalProperties
Dim StatV4 As IPGlobalStatistics
Properties = IPGlobalProperties.GetIPGlobalProperties
StatV4 = Properties.GetIPv4GlobalStatistics
Dim Packets As Long = StatV4.ReceivedPackets
What actually is a 'packet'? Can I calculate the download/upload from this code by maybe multiplying the recievedPackets by packet size... or something like that?
Alright, so my family just got on a new wireless Broadband Plan, and I'm curious as to who actually uses the most downloads each month, so I figured I could do this easier using a program, rather than recording everything using pen and paper.

View 2 RepliesI want to create an application that able to calculate the total time the user (i.e. myself) spent on a particular application, for example Firefox. And this application should display warning message if the user spent a lot of time on Firefox (for example 1 hour or more)Reason: I'm a VB.NET developer. During my working hours, my main tool is Visual Studio and I suppose to do coding. But I need Firefox occasionally to access internet (particularly SO and other sites) to find solutions for my programming problems. The problem is I addicted to SO and SO sucks my time for hours until I have forgotten that I suppose to continue coding and not browsing the SO site.

View 6 RepliesThe pay rates for the project are:
a. Level 1 - $10.00
b. Level 2 - $12.00
c. Level 3 - $14.00
d. Level 4 - $16.00
e. Benefit Deduction Rate - 0.10
f. Overtime Factor - 1.5
For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.
When the Calculate button is clicked:
a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.
1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.
2. If the user chooses to continue processing, the focus must be set to the Hours text box.
3. If the user chooses to quit, the program must close immediately.
b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.
1. The pay rate is determined by which Job Grade radio button is checked.
2. For hours less than or equal to 40, the total pay is the hours times the pay rate.
3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.
4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.
5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal
places.
6. The focus must be set to the Hours text box.

View 6 RepliesIm wondering if there is some way of monitoring individual processes (read: not mine) cpu usage and ending (asking politely then killing it off) the offending process. I dont know about you, but i've been in multiple instances where i've been unable to get to taskmanager to "choose" process to be killed. For multiple reasons (Either taskmanager has been visible, but a game window is still showing (alt+tab not working), leading to a guess game of clicking processes or cpu usage has been so high that one mouseclick takes 30 sec.)

View 2 RepliesI have seen a different behavior before, but this time my application just doesn't work properly when debugging, while it does everything perfectly after compilation.
My project is beginning and does just one thing: monitor the clipboard and save its contents to a XML. It has just one form (frmMain), which, when loaded, puts itself in Windows clipboard listening, via WIN32 API. Then, whenever receives a message, the form has to check if it's from clipboard and, if so, saves the actual contents.
The code is below:
Public Class frmMain
Private Const WM_CLIPBOARDUPDATE As Integer = &H31D
Private XmlDocument As System.Xml.XmlDocument
[CODE]...
So, as I've said, after compiling, everything works perfectly. However, when debugging the "AddItems" function is never called. I set a stop point in the line Win32 API is called (in frmMain_Load) and the execution NEVER STOPS THERE! Debugging line by line, I found out that after executing some lines from frmMain_Load, VStudio just jumps to WndProc and never comes back to frmMain. I mean, the form is shown, and the rest of its initialization code is never executed. Because of that, my form is never added to clipboard listening (this command is at the end of frmMain_Load) and, consequently, all messages my window receives are not from clipboard, and, therefore, nothing is saved.
Is it normal to VStudio just bypass some code because a event triggered other method? This could lead to lots of complications and it's not consistent with after compiling behavior. A proof that what I said is actually happening is this: I passed the last 5 lines from frmMain_Load (where the Win32API is called) to the beginning, so my program would call the API before initializing the XML file. OK, now what I have: the API is called, but the XML commands are never executed. Consequently, "AddNewEntry" is called, but I have a null-reference error, because my XML was never initialized. Have you ever faced that bizarre behavior? What can I do so my debugging is correct and I don't have to compile my program for each test I want to do?

How can i calculate total time?
I have a sql SELECT statement in vb.net. I have this line of code to calculate a specific percentage of the Net Total:ROUND(Invoices.NetT*'" + txtOnGoing.Text + "'/100,2) As Commission 'txtOnGoing is a text box which pre populates a certain number e.g '10'... this means 10% of the NetT column..The above code works fine, now I want to add the "Commission" Column and display the Total in a text box. Does anyone know how to do this? I know I can use the SUM operator but because the Commission column isnt a column that actually exists in the table I dont know how I could do this.

The program is for calculating an amount of fruit. I have a label saying the name of the fruit, a textbox to enter a value of 0-99 and another textbox with ReadOnly which will show the price.
A little picture here:[URL]
As you can see, the Fruit1 Etc... Is only the fruit name.
The Text box wich indicate 1-99 means the number of fruit.
The Textbox with Cash on it, means the total price.
The Calculate button, when I will push it, all the total price from all the fruit will be added together to form a total price which will be indicated in the total price textbox under the Calculate button.
When I will enter the number of fruit, if I enter 99, it give me a price.
When I will enter 60, I want that the 60 are multiplied by (let say) 0,10$
I just like to know how I can do this... Its really bothering e and I don't want to calculate all the things and make 99 line for 1 fruit cause it will be long.
The code I was using was:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text = "99" Then
TextBox2.text = "10.00$"
Elseif TextBox1.Text = "98" Then
TextBox2.Text = "9,90$"
EndIf
End Sub
Until the the number of the fruit in the code reach 0. So its very long.
I have successfully written this interest calculation, although it is based on the ppmt function and adding up the interest from each payment. This is quite a long looping process.. And it is not accurate because of the rounding of each payment. I was wondering if someone knows if there is a formula I can use, or if the pmt function is capable of this? (e.g. Mortgage payment - total interest payable over 30 years at 5% ( principle and interest repayments))?
