View 1 RepliesPlotting An Array Of Points On Button Click
May 9, 2011I have an global array of points that i want to plot in VB. say X and Y points, and typically they have values of +/-12000. Now I've not done graphics work for a long time and when I did, I used OpenGL with C. Now I need a GUI i'm using VB 2008. Firstly, what's the best method of rendering the array of points? should I use some port of OpenGL? GDI? or what?
Secondly, can I simply print to perhaps a Panel on hit of a button? Thirdly, do I have to place any line drwing code in an "OnPaint" event handler? Finally (for now) if my array represents points in a space much larger than the painting surface, how would I scale and scroll the final image within the the proposed Panel? I look forward to your advice.
VS 2010 Using Array Of Points With E.Graphics.DrawLines
Apr 30, 2010I've rewritten my program so it would be more .net friendly (meaning I try to draw in picturebox.Paint event).
I try to use DrawLines using array of points, which are added by user one by one, but I can't figure out how to force my program to only use points that have been set by user and not the whole array.
When I call DrawLines pointing at my array of eg. 10 points and only 5 had been set, I end up with a nice set of lines with the last going to the upper left corner (0,0) and supposedly staying there for 4 more points, which is unacceptable.
I think of using ReDim Preserve each time, but I am not sure if it is the most efficient way to do this.
Anyone can think of something more elegant before I implement this redim monstrosity?

View 1 RepliesAdd Data Points From Double() Array To Existing Chart Series?
Jun 21, 2012I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?
View 1 RepliesHow To Create Simple Points System For Game
Mar 30, 2012I am creating a points system for a game, this is the code I have but it isn't working as I want it to.
Dim intScore As Integer = 10
Dim intNumOfGames As Integer = 0
intNumOfGames += 1
intScore = intScore - 2
The user will start will a score of 10, but everytime they click the button the user should lose 2 points off the score. But my code above that doesn't happen, when the user clicks the button it only happens once leaving the user with 8 points throughout the game.
Converting DLL's Created With Intermediate Language To Create Entry Points Within A DLL
Nov 16, 2009In need of some desperate help. Has anyone had any experience with a software product called Pres? The programme provides a function (userhook) that can run externally created dll's as the programme offers no COM support. The basic requirements for the dll are as follow.
1, The dll requires a public function named UserInstruction
2, The UserInstruction must have 5 parameters. The first and second of type long, the third a double array and the fourth and fifth parameters required type is a string.
This all seems pretty simple. But as .NET doesnt support exporting functions within a DLL to allow direct public access to the function through third party software it becomes tricky. After doing some research it seems as though this isn't possible in .NET. The only way I can see to do this is to convert the dll to Intermediate Language and play around with it once this is converted and then convert the IL code back to a DLL. I found this on the following site [URL]..After trying this when I try to use the DLL via Pres I am still getting no joy.

View 1 RepliesCreate A Fake Array Using Generics Instead Of Using An Array
Jun 23, 2012This was an experiment to see if I could create a fake array using generics instead of using an array. I decided to try it, because I may use it if I find any advantages to using it over an array. it works, I am just asking for a second or third opinion, have I screwed anything up, or is there an easier way to accomplish this? If I use it, it will be for a 2D game I am creating, and is used to draw the 2D screen graphics, placing an image based on what image identifier is located at what coordinates. The value stored in the fake array is an integer that disignates the graphic to draw and whether it is passible or not, i.e. 0 = a floor image, 501 = a wall image that is impassible (any image number > 500 is impassable) The Class definition:

Create An Array Of An Array (or Arraylist Of An Arraylist) To Hold Strings?
Mar 20, 2012I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?

Create Array With In A Class?
Aug 12, 2009I'm writing a ray tracing program that uses snell's law to trace rays through a system of lenses to examine abberations in a given design.I have a class called lens, which holds variables for example, name of the lens, description, number of elements.I want to be able to have a sub class or array within lens (or some other way to manage this data).I wont know what number of elements is until run time.
So I would need to define the array at run time.Part of the idea of my program is randomly generate lens elements within given rules (as in a massive lot), keep the top designs and continually refine them by making billions of micro adjustments to the variables that define the lens etc, which I can pick up later on as it'll save the database/variables.For example, say Lens(63).NumberOfElements = 6.
I want to be able to access Lens(63).Element(3).Radius1 Etc, there will be a bunch of variables under Element, such as Radius1, Radius2, refractive index, horizontal diameter, vertical diameter, and spacing between the next element if it isnt the first.
And Lens(70) may only have 4 elements etc. How can I define a different array size like that in the class under different parent array indexes at run time?
