Replacement For Random Access File In VS 2010?
Sep 3, 2010The application reads information similar to a DXF file. For purposes of discussion, the data consists of lines, those lines have endpoints, x1,y1,x2,y2. Within the file those lines create "paths", in other words, they are connected. There can be many separate paths within a single file. However in the original file, the geometry is not in any particular order, the paths are not indicated.

Nov 26, 2011I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background.

When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

View 3 RepliesFile I/O And Registry :: Random File IO In VB 2008?
Feb 28, 2012I have managed to learn a little of VB 2008 but I'm still struggling. I managed to convert one VB6 program to VB .net but all the file IO in it is sequential access.I'm trying to convert a VB6 program to .net. This program uses almost entirely random file IO.In one of the books I have, I found an example which, with a minor mod worked. I tried using that code to modify my program and it does not work. In my code, the FileGet results in the obj containing null strings. Yet in the sample program using the same structure, the obj contains actual data.The file is being opened because the record count is calculated correctly [iUpper = LOF(F_Trk) / TrkLen].
I used a Type in VB6 which I converted to a Structure in VB 2008. The function in which the problem occurs is below as well as the Structure declaration and the Function it calls (PAB) which is a derivation of the PathAddBackslash API call.Is there an easier, more efficient way to achieve the same results in VB .NET?[code].....[code]......

View 7 RepliesVS 2010 Picking A Random Number Only Once?
Oct 6, 2011I'm trying to figure out how to make a number be randomly picked but only picked once when a button is clicked. I've got the simple random number code down already but I can't seem to figure out how to have it picked only once.This is basic random code that I'm using right now.
Randomize()
Dim value As Integer = CInt(Int((14 * Rnd()) + 1))
It picks out a number from 1 to 14 and returns it as an integer in "value", and I'm using to set that to open a specific form but I don't want that specific form to open more than once in a session. So if the number three was already picked out then it could never be returned ever again.

View 2 RepliesVS 2010 - Picking Random Items (weapons)
Sep 21, 2011how to go about picking the random weapons. When you generate a random class, the user must first enter their current rank (level). This is because you are unable to use certain guns until you reach a specified level. This keeps the program from giving out guns the user can't use. What I am doing is allowing the user to give certain parameters as to what type of gun they want to use (or don't want to use). For example, I have checkboxes for the user to pick if they want assault rifles, SMGs, LMGs, Snipers, Shotguns, RPG, etc.
I did this in another version of this program I made, but the only option was to pick whether or not you wanted RPGs included. So, it was easy enough to check if the weapon was an RPG and if it was simply generate another random weapon. I could do this, but with the number of options there are, I don't think this would be the best solution.

VS 2010 - Random Sequence Generator For Names
Mar 1, 2012For a school project I need to create an application one element of that it puts 14 names into a random order, I figured the best way to do this was with an array and a for/next loop (it cannot repeat the names) each name would be declared as a string with the name of the variable being a number between 1,14. Then there would be a text box relating to each index of the array, I am sure you get what I mean. However, my for/next loop seems to be getting stuck and causing the application to halt and I cannot seem to work out why.
Here is my code.
Public Class Form1
Dim iNumber As Integer
Dim arrNumber(0 To 13) As Integer
Public Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have yet to write in the section which converts the random numbers into the names, as I discovered this error whilst debugging the for/next loop.
