For a school project we need to visualise a computer network graph. The number of computers with specific properties are read from an XML file, and then a graph should be created. Ad random computers are added and removed.Is there any open source project or algorithm that could help us visualising this in VB.net? Or would you suggest us to switch to java.
Update: We eventually switched java and used the Jung libraries because this was easier for us to understand and implement.
i am working on project of using ant colony optimization and espcially on antnet algorithm but i have many problems in programming of this algorithm, and since i dont perfer using simulation for that purpose.
I want to write a simple beam search algorithm to solve a maze (like a tree, and the output must be the shortest path).So, if anyone have tried to write a beam search algorithm before, preferably in VB.NET language, it would be great if you can share it in a pseudo-code format.
Because, I have no idea on how to write the algorithm. I have tried to Google it, but I understand nothing.I found this source though (which I don't understand at all XD) [URL]..So, back to my question, how to write a beam search algorithm? Preferably, in VB.NET language and pseudo-code will be enough for me (an actual example code will be great though
WHERE IS MY Problem. Develop a COMPLETE algorithm using pseudo code to solve the following problem: Your network contains hundreds of workstations. The primary local drive (C on each of those workstations may contain many folders immediately under the root folder. You need to search each of the folders under the root folder on each of the workstations to see if the file nasty.bug exists. You need to do two things with respect to this file. First, count the number of times this file is actually found and, after all the workstations have been scanned, display a message indicating the total number of occurrences of this file across your network. Second, whenever the file is found, it should be deleted.
I am trying to write a code about counting inversion algorithm.I finished the code but the result was wrong..I dont no where is the problem but I think it is in the count-merg function [code]
I have a standard scoring algorithm but I need to help on a piece of code to only execute the scoring algorithm at certain times.I want it to be triggered by dates, but the problem arises if the program is used after 2 (or more) dates have passed, the first date will not be added as the second date is the newest and therefore the one that triggers the scoring algorithm. - The scoring algorithm gets the scores for that week, which are stored in a text file.
I want to find a way to speed up this code.if you look at the condition of If calculated Then in the code below, this is what slowing down the code.While the code provided seem fast with Const initBit = 4 try it with something over 12.
I want to be able to use this code (with calculated param as True) with initBit of 20 or more.
Beware that 20 or more might require a gig or more of ram and/or compiled as x64.
C# code (converted with an online tool from VB.NET):
I am trying to implement an Algorithm called "Diamond-Square Algorithm" I am having trouble ending it so that it retiurns the required result. So far I have the folloiwng.
Anyone have VB.Net or VBA code to ascertain if an Excel Object is positioned over (Hiding) spreadsheet data?I have code to create/position a chart object. Where would I begin to determine if there is data "under" an object.
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:
EDIT: Solved (see comments) I have a For loop inside a sub, and right below it I have a MessageBox function. Everything compiles correctly, however for some reason, if the loop executes and exits successfully, anything outside and below the For doesn't get executed.
[Code]...
it displays only 10 items in the ListBox afterwards. I've searched everywhere, but I did not find anything related to such an issue. I'm kinda puzzled, anyone got a clue of what's going on? EDIT: Forgot to specify, the sub is actually a TextBox.TextChanged event
So my teacher gave us this assignment that I'm having trouble understanding why she wants us to write outside of the button Private Sub.1. Write the code for the Calculate Total and Grand Total button a. Declare a variable to accumulate the individual totals outside the sub procedures b. Calculate the total by multiplying the selected number of atendees by the selected cost, and display this total in the label next to Total c. Calculate the grand total by adding the total calculated in step 3.b to the grand total variable. Display the grand total next to Grand Total I'm don't understand why she says 1a. I feel like you can just write all the variables in the same Sub on the calculate button.
Basically, if you go to Start and click Computer and then click on the Network link on the left hand side, you'll notice on the right hand side several categories, one of which is titled "Network Infrustructure", in that category, my router is listed, and in my case, it is "LINKSYS WAG160N Wireless-N ADSL2+ Gateway" and when you right-click and select properties, it lists basic info such as internal/gateway IP address, on mine it is "192.168.1.1" I would like to know how to retreive this information in code, preferably a Windows API so that i can call it using a legacy VB6 app. Also, even if you just know a .NET version or a Delphi version, please do list that as well as i can code in both. However, the answer i'm ultimately seeking is a method to access this via VB6 so that would probably be a WinAPI call (will upvote & select this as answer), however, other methods are also welcome incase i can't find a legacy method (i will upvote these).
Have to develop an application that will let me choose between cell phone plans, individual and family plans i have the forms and all choices done,. new forms open and old ones hide to keep it clean. i think i got all the variables declared, and got no debugging errors, but when i select the options, it always gives me the following:
1. adds one more phone than selected
2. only shows phone subtotal, tax and total
3. prices for options and monthly fees never show
Here is my code for all 3 forms
Public Class frmMain Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click End End Sub
I am developing an ASPX VB.NET file. My assignment is to convert an integer representing week of the year into that end date. For example, if user selects Week 4 for 2011, I want to get date = 1/22/11. How do I do this in VB.NET?
I'm supposed to change the keyboard language to Farsi(Persian) by using API functions while the program is running( It's a plain form with a text box). I'm already late for the due date.
I have two drop down boxes in my program. When you select an item from the first drop down, it populates select-able items in the second. When I select something in the second and then change the selection in the first one, the values remain in the second. How do I "reset" the second drop down when the first is changed?
displaying the first 10 Fibonacci numbers. My code displays the following result: 1, 2, 3, 5, 8, 13, 21, 34, 55 and I need it to also display the first two Febonacci numbers (0 and 1). How would I do that?
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a As Integer = 0
If i have a class called A and a class called B, if B inherits A that means A is the super class and B is the subclass. I have been asked to describe why class A is not an abstract class but as i see it class A is an abstract class A, as it has been created for Class B to use in the future, is it something to do with Class B not being able to access the fields in Class A as although they are private by default?
I am trying to unit test for data being input into a textbox (txtPrice). If it is not numeric, it throws a messagebox stating that the input must be numeric. However, when I unit test, I can't figure out why my test fires the message box twice.THis is my (simple) unit test:
Public Sub txtBoxes_LeaveTest() Dim target As frmEstimate_Accessor = New frmEstimate_Accessor ' TODO: Initialize to an appropriate value Dim sender As Object = Nothing ' TODO: Initialize to an appropriate value[code].....
My understanding is that for unit testing, you declare the sender, and (in this case) set the sender to some value that will trip the message box. 112L should do this on the leave event. I then write my expected, which in this case is 112L, fire the event, and then get the actual out of the text box. I then Assert.AreEqual to ensure the expected and actual are the same.
Working through trace tables and wanted to check to see if my results where correct, I have designed the following code to check each stage of the loop, but the code keeps throwing up an error about casting when i try to run it. I can see when the error comes back that the writeline is holding info but what have i done wrong.
I would like to ask something about Network in VB.NetI try to search network code sample to produce VB.Net application (Like Server and client)But I found a lot of codes (Server and client) and the codes are very complicated for me because codes are mixed with chatting process So I would like to know or want some sample Network VB.Net application(code) the application has two forms
form1(server) and form2(client)
form2(client) has (one button or textbox)
form1(server) can make visible or invisible (button or textbox) of the form2 (Like that code, I can able to make or learn other processes) I want to know how to code it. If I can get the code, I can learn more smoothly with various way
Dim fs As New FileStream("C:Womanizer2.m4a", FileMode.Create) Dim writer As New BinaryWriter(fs) Dim reader As New StreamReader(networkStream) 'Dim send As [Byte]() = reader.ReadBytes(fs.Length)
[code]....
These are two code blocks from the two programs I have wrote. The first is the server program that receives a connection and writes the file to disk. The second is the Client program that sends the file to the server to be written to disk.As it is - it hangs. I did once get it to write to the disk - but the file was twice the size of the original. what objects to use for transferring a file over a TCP IP network connection with TCPClient and TCPListener.
I've been taking a class on it this semester and am starting to get very confused and behind. I've been pretty stuck on my hwk assignment for this week and was wondering if anyone could possibly hint at what I'm doing wrong or if I'm just completely way off. The whole rows and columns in arrays seems to be throwing me off now. Also, sorry if this is not the right place to post something like this I was not sure which section this fit under.
