Hi thanks alot for the code. although Iam still having trouble finding the angle of intersection between two lines. what Iam trying to achieve is to get the reflection of a line once it intersects with another line. Kinda like a mirror image of the line. Please help. I am using vb.net 2005 cheers

Hi I need help on how i can find the angles and point of intersection between two lines that i have drawn on the form. I am using VB.net 2005

No its not too late to reply. Anyway I still havent found a way around it. And yes, i have set the database fields on the crystal reports right.

Hi guys I am new with crystal reports and i am trying to load a crystal report wirh data . What i want is to display just one record on the crystal report.

hi how do i go about creating tables in an existing access database from vb.net 2003?

thanks, i hadnt seen the link

the variable am tryin to use keeps changing depending on the circumstances, but i need this variable to be passed onto another form or class.declaring as as constant doesnt seem to solve the problem. i do not want to use a module since i dont understand modules well in vb.net2003. any other ideas? :p

please gimme a code snippet showing how i can pass a variable from one form to another.vs 2003

:p hi is it possible to declare a variable in such a way that it maintains its value even in other forms. iam using vs.net 2003

how can i display a form without the title bar? iam using visual studio.net 2003 :D

thanks a bunch pal, everythin works fine now

ok i have an access database.iam able to read the contents of the database and insert them into a linked list. i have created a linked list class from scratch with methods to insert and delete a node. that is working fine. the major problem is traversing through the linked list and displaying the contents of each node into labels, or a listbox on the form. iam using visual studio.net 2003. this is what i have: the linked list class Public Class ListNode Public data As Object Public link As ListNode Public list As ListBox Public Sub New() data = "empty" link = Nothing End Sub Public Sub AdditemTop(ByRef LN As ListNode, ByVal obj As Object) If LN.data = "empty" Then LN.data = obj Exit Sub End If Dim tempnode As New ListNode With tempnode .data = obj .link = LN End With LN = tempnode End Sub 'list Public Sub Traversal(ByVal LN As ListNode) If Not LN Is Nothing AndAlso LN.data <> "empty" Then MessageBox.Show(LN.data) Traversal(LN.link) End If End Sub Public Sub remove(ByRef LN As ListNode) If LN.data = "empty" Then Exit Sub End If If Not LN.link Is Nothing Then Dim temp As ListNode temp = LN LN = LN.link temp = Nothing Else 'there is only one node left LN.data = "empty" End If End Sub End Class the method called traversal works fine. it displays the contents of each node on the messagebox. what can i do to have it displayed on a listbox or labels on a form??

thanks for your response actually i need help in creating a procedure that would traverse a linked list and return the data in each node in the same order they were entered

iam learning vb.net and i need help in understanding the linked list class. i have this assignment am trying to do Introduction Ourworld is a travel company that provides worldwide flight routes for travellers.The company wants to improve the way in which it creates records and maintains flight routes. It is proposed that the flight route for each traveller will be defined by a linked list. Each node that forms part of such a linked list would be an airport. The resources available at any airport would be detailed via a suitable database. Entities such as Destinations, Date, Time, Carrier, Flight Number, and Seat Class would be part of the information stored in the database for each airport. Aims Produce a prototype of a software system to demonstrate to the management of Ourworld by: 1. Designing, implementing and testing a linked list class. Any linked list object instanced from this class must include the properties and methods: � Forward link � Node Text � Add/Insert node � Remove node 2. Designing, implementing and testing a procedure that would Traverse a linked list generating a graphical representation of the linked list using label controls. 3. Designing, implementing and testing a simple database to demonstrate how clicking on a label control, that represents a node of the linked list, the detail of that part of the flight route could be displayed. Task 1 Design an appropriate linked list class by carefully considering all the properties, methods and events demanded by the application outlined above. NOTE that you may wish to design a node class before you design the linked list class. Pay attention to any data validation that would be required. Task 2 Implement and test the class designed in Task 1 Task 3 Design a procedure for traversing the linked list and displaying the node text properties in a collection of label screen controls. The procedure should show graphically how the nodes of the linked list are connected. Task 4 Implement and test the procedure designed in Task 3. Task 5 Design a simple database that would be sufficient to demonstrate the information that would have to be associated with each node. Task 6 Using Microsoft Access set up the database designed in Task 5. Populate the database with suitable test data. Task 7 By using a suitable event, which should have been designed into the linked list class, implement the means by which a click on the label that represents a particular linked list node produces a display of the database data stored about that node. please help!!!!!!!!!!!!!!!!!!!!!!!
