Anyone knows where I can download binary search tree for VB.Net ? I'm working on a small project for my company and I'm thinking of using BST as a sorting tool.I used to do BST using C++ and I was using linked list. I'm not sure if that can be done in VB.Net but is there any other ways? any input and comments are welcome.
I need to compare two tree-structured reports and show comparison results in a datagridview in vb.net. I think using tree structure should be efficient. But note that I DO NOT use a tree view to display results (I found a lot of help in tree view though). All I want to do is to construct two trees, and then search the trees and compare. I do not know how to write this in vb.net.
I have a delete method for a binary search tree. It only deletes the last two entered values. When trying to delete the root or anything to left of it it returns a null pointer exception.
PublicFunction Delete(ByVal key AsInteger) AsBoolean Dim current AsNode = root Dim parent AsNode = root Dim isLeftChild AsBoolean = True While (current.value <> key) parent = current If (key < current.value) Then isLeftChild = True current = current.rightNode Else

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
Couldn't think of a better title.(Background on the problem/me)Okay, so, first question/post here, so hi. Now that that's done with, the information pertinent to my problem. I'm fairly new to VB (and programming as well, aside from screwing around with C++ and learning assembler(well, attempting is the better word) god knows how many years ago), and have only seriously been programming for about under half a year, and my skill level is about at that stage. Only been using VB.Net, nothing older. Depending on the time of day and if I'm home or at school, I fluxuate between VB express and Vis Studio 08. Umm, this program I'm having trouble with was on a test that I took yesterday (took the problem home with me cause I really wanted to figure out what was wrong with it).
The stipulations of the test were: No For->Each Loops No using Built-In Sorting or Searching Functions
I'm creating a search function to search through a binary file and find a record based on the users input. Surprisingly, that isn't the problem! The problem I'm having is that as part of this I'm using a procedure to display results in text boxes, and I'm getting the error "Too many arguments to private sub display customer"I've encountered this error before, but never really knew what it was... Here is my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click FilenameCust = "F:\College\CustomersFile.bin"
As I am to VB.NET, I would like someone to help me on SearchButton code. I am using MS Access database. I would like to get the result of search commond into ListView.
I have converted this parallel extension c# code sample to VB.NET
[URL]
using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)
Return SendTaskCore(ping, userToken, Function(tcs) ping.SendAsync(address, tcs))saying that ping.SendAsync(address, timeout, tcs) does not produce a value
2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
I'm looking for a control like the image bellow, treeview combined with a listview, and with editable cells.does someone have a sample code or some information on how can i do this?
I recently aqquired VB 2010 Express but have limited programming experience.I am looking for sample code and/or literature which will show me how to plot a Y=f(X) curve - for example code which will plot a straight line, a parabola, etc.I need it as a template from which I can learn about how to build such a graphing program and then tailor one to my needs.
I have a vbscript that does the following but I want to do it in vb .net and was hoping someone could post some sample code to get me started. The script does the following. Monitors 2 folders specified in a config file. When a zip file is put in the one of the folders it us automatically unzipped to a working folder and then the zip file is renamed to unzipped-<zip>.zip. I am hoping someone could post a visual studio project or code that might help me get started.
I am trying to write a program which performs a binary search. The user will input the name of a state in a textbox.I have a listbox which is populated with the 50 states in ABC order.The middle of the list must be determined and then determine which half of the list the state may be located. If the middle item is less than the state name the state should be in the second half of the list. If it's greater than the state name is should be in the first half of the list. The calculation for looking at the middle itemi the list is:
middle = CInt(first + last)/2)
There is a variable 'flag' which is initially set to false and then will be set to true if the state name is found. The variable first is initially set to 0 and last needs to be set to one less than the number of items in the list.Below is a very rough program fragment.
Code: Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click Dim i As Integer Dim flag As Boolean = False Dim first As Double = 0
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click Dim counter As Integer = 0 Dim t As DataTable = DirectCast(Session("MyDataTable"), DataTable) Dim row1 As DataRow = t.NewRow() If (isUnique(t) And counter < 30) Then row1("ID") = counter + 1
I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...
Is someone can give me an example in code making in searching for telephone numbers. Im just a begginer with just a little knowledge in coding. Any simple example that can give me hints on how to start a code in searching of telephone numbers.
I know how to genrate a serial number using GUID. How can I use it. Suppose I send a CD with the software to someone. I do not want just anyone to use it. They have to have the KEY or SN. How can I impliment it so that if you do not have the s/n / key then you will not be able to install the software.
When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.
I am looking for sample code for vb.net Dynamic Dashboard applications? i want the code in vb.net which will be my front end and sql will be my back end for database?
