Create And Search A Non-binary Tree?

Jan 17, 2012

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.

Create A Custom Tree(view) Structure?

Jan 1, 2012

I'm looking for a way to create the treeview structure in memory with a classes, so I can loop through them, like with a collection and easily load the data into a treeview, listview, datagridview or simply work with the data in the background.

There's a treenode class that I could use, but I've noticed that when I have a lot of data in the nodes, it has a lot overhead when for example serializing, because it also saves the checked state, imageindex of the nodes and things like that, which I never need. The saved file is about 10 times bigger than the actual data, which is not acceptable.

Create A Tree Based On Path Of Object?

Sep 20, 2011

I have a bunch of objects, they aren't in XML but the xml document would look like this[code]...

The tree is obviously very deep. Does anyone have an algorithm to create this into a jstree, series of "UL" and "LI". It would be christmas if you had the code in vb...but I will be satisfied with just the logic. My thought is to eventually make this into a jsonp web service so I can use jstree to build a tree, but for now im just trying to understand the logic necessary to parse this correctly.

Tree.SelectedNode = Tree.Nodes(0) 'returns Error With System Reserved Partition?

I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.

C# - Create An Expression Tree To Do The Same As "StartsWith"?

Dec 29, 2010

Currently, I have this method to compare two numbers

Private Function ETForGreaterThan(ByVal query As IQueryable(Of T), ByVal propertyValue As Object, ByVal propertyInfo As PropertyInfo) As IQueryable(Of T)
Dim e As ParameterExpression = Expression.Parameter(GetType(T), "e")

[code]....

It works fine and is consumed in this way

query = ETForGreaterThan(query, Value, propertyInfo)

As you can see, I give it an IQueryable collection and it add a where clause to it, base on a property and a value. Y can construct Lessthan, LessOrEqualThan etc equivalents as System.Linq.Expressions.Expression has this operators predefined.How can I transform this code to do the same with strings? System.Linq.Expressions.Expression don't give me a predefined operator like "contains" or "startwith"?

Enhancements To Class Diagram?

Jan 28, 2009

I have built a class diagram for a proram i am building in vb, and i need some help to enhance it.The program description:"Modeling Car Parking System Modeling Car Parking System (MCPS) is the software that manages a parking for cars. The dedicated employees in that parking will use this system to control the parking. This software will facilitate the work in the parking and covers most activities performed, such as booking, cashing, and organizing. In the following, we will provide a comprehensive description of the parking (the scope of the system) followed by a description of the system with the functions that will be performed.

The Parking (The scope of the system)The parking consists of two floors, with a capacity of three hundred car places, and opens 24 hours all the week�s days. It has two main control stations; one is located at the entrance gate, and managed by an employee whose main functions are entering data to the system, then providing a receipt to the driver, and the other is located at the exit gate (cashier station), managed by an employee whose main functions are checking the receipt, entering data to the system, cashing, and providing an invoice.

The parking has three barriers, two main barriers are placed at the entrance and exit gates, and the third one is located at the second floor�s gate. They are controlled by using a remote control.When a driver wants to park his car, he has to drive it to the entrance where an employee (receptionist) will enter the car plate number to the system, then prints out a receipt to the driver. This receipt will contain information such as, the car plate number and the entry time. After that, the receptionist will open the barrier to allow the car enters the parking.

Inside the parking, the second floor will be kept empty (closed by the barrier) until the first floor will be full. When the first floor becomes full, the employee will open the barrier to allow the cars to park in the second floor. A driver can park his car in any vacant place in the available floor.When a driver wants to leave the parking, he drives his car to the exit gate and presents the receipt to the employee in the cashier station, who in turn, will check if the number recorded in this receipt (at the entrance) is similar to the real plate number of the car. After that, the employee will enter that number to the system, take the money, provide an invoice to the driver, and finally, open the barrier to allow the car leaves the parking.The list price in the parking, declares that parking a car for an hour costs 3850 LBP, and each extra parking hour will cost 3000 LBP.

Description of the System :The system will operate 24 hours, and will perform the tasks related to the work in the parking. The following scenario will explain what we mean by �will perform the tasks� in the parking.

At the entrance gate, the employee will enter the car plate number to the system as a (driver ID), and select the available floor which is in service from a menu. The system, in its turn, will store these data and additional data such as the time entered, and then issues a receipt including information such as driver ID, entry time, date, and the available floor reference.

At the exit gate, the employee will enter the car plate number (driver ID) to the system which will generate the data related to it, and prints out an invoice including the current time, date, total parking time, and the total amount of money (parking fee); since the parking fee and the duration will automatically be calculated and displayed by the system.

In addition to the tasks which the system will achieve at the entrance and exit gates, it also will provide statistical information such as the total count of cars that exist in the parking at any time, and the number of the vacant or busy parking lots (car places) in each available floor. Also, the simulation which will be part of the system will play a role in managing the parking since it will show an up to date comprehensive scheme of the parking.

The graphical simulation of the car movement flow When a car will enter the parking, and after an employee has implemented all the tasks associated by the entrance such as entering the car plate number, and selecting the available floor, the system will issue a receipt and automatically will lead the user (employee) to the simulation part. The simulation part is a form that contains cars and parking lots as graphical components, when a user click such a button �Drive-in a car� a car will move to occupy an available empty parking lot.

When a car will exit the parking, and after an employee has implemented all the tasks associated by the exit gate such as entering the car plate number, the system will issue a receipt and automatically will lead the user (an employee) again to the simulation part. When a user clicks such a button �Drive-out a car�, the car will leave to parking lot was occupied.

VB2008 Much Slower Than VB6 - Drawing A Small Diagram On The Screen

May 17, 2010

I'm upgrading to VB2008 from VB6 and have noticed that when drawing a small diagram on the screen it is much slower. In VB6 is is drawn 'instantly' in VB2008, 34 lines, 5 arcs and 15 text items are taking 112000,000 ticks to draw- I can see it being drawn line by line. The codes contains the code to draw the diagram and some minor calculations to determine what to draw. If I just draw 4 lines directly it takes 80,000 ticks which looks 'instant'. It looks as if the calculations are slowing it down. Is there some reason for this, is there a box I have not ticked that makes it slow?

Build And Display A Simple Diagram That Is Built From Data Entered By The User?

Aug 22, 2011

I wish to build and display a simple diagram that is built from data entered by the user. Because I can't post a picture of the types of diagrams here I'll use the following example. Image a picture of a house as a child might draw it a large square, with a triangle for a roof, a rectangle for a door, and two smaller squares for windows. Now I want to build an application that lets the user enter data and change that drawing according. For example, by entering the length and height of the house the size changes, change the number of windows, size of the door or height of the roof.

Now this may seem like a useless application but keep in mind the house is just an example the real purpose is different but should be as simply drawn. I'm looking for suggestions on make this work. Should I use a paint? or is something like this better done with a tie into the Visio references?

Create A ComboBox In An Inputbox?

I can manage everything else except making the sheet selection a multiple option one.

At the moment the name of the wanted Excel sheet is typed into the text field in the inputbox. But I want the textfield to be a dropdownlist which would be populated with this:

With ComboBox1
For i As Integer = 1 To XL_WB.Worksheets.Count
Dim nimet As Excel.Worksheet = XL_WB.Worksheets(i)
