I am wanting to create a rectangle for two points (vector). I need a function that takes two points and a length and calculates a perpendicular point from line (vector) AB, to a given length.
I found this code, however it doesn't seem to work.
[Code]...
Looking for something like:
dim rect as system.drawing.rectangle
For each point in rect
Debug.print(point.name, point.value)
Next
I'm making a game that needs to hit test a Rect object inside 4 points that basically forms rotated a rectangle. This means I can't use the Rect class's IntersectsWith function to hit test. So my question is: if I have 4 points that creates an imaginary rectangle of any orientation, how can I tell if another rectangle is inside the "fence" so to speak?

How to make back-up and restore point? what I want to happen is when I click the button back-up. It will generate a back-up of database in access on the current date. And if I click the button restore. the system will restore the last back-up point. So that when there is a file accidentally deleted, the system can retrieve it again.

View 1 RepliesI am attempting to draw and fill a rectangle using percentages passed through the text properties of 4 textboxes. I am attempting to do this in VB 2008. For example:
textbox1, 15%, green

textbox4, 10%, orange
I 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.
is there a way to offset the points in a polygon without having to change each one individually the points are in an array
View 2 RepliesI need to calculate a couple of lengths and an angle, so basic trig. Embarrassingly I can't remember enough of my school trig to sort this out in my head.
Here's the problem pictorially, I need to calculate the two variables in red text (with light blue background) where Radius can anything between 1 and "r.Height /2" and r.Width can be anything between >0 and Radius.
The only other thing I can tell you is ther total width of the dark blue rectangle and the % of that width that r.Width represents - I didn't include it in the picture since it didn't seem relevant.
Ultimately I am trying to create a rectangle to use with GraphicsPath.AddArc.
In 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.
i've got a little problem with List(on T) variables.
[code]...
It works perfectly fine. Does anyone know what the problem is?
Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET

I'M creating a kind of photo viewer, and I cannot figure out how to orient the scroll buttons with the photos I want to draw because they all are different sizes.This is really hard to explain so please ask questions if you don't understand.I'M thinking if i could draw every photo on a single rectangle and then the scroll bars will position that rectangle up or down. but is there a way to make a rectangle inside another one so it only shows inside that rectangle?

Then I would like to press an "Export" button and save the displayed shape coordinates/vertices back to a file location of my choice as a .txt file.

View 1 Repliessuppose i have a tree that have a root node. that root node have 3 child nodes. each child node have 3 child nodes and so on say up to level 4. if i number each node from the root node and numbering from left to right, the root node being number 1 and the left child of the root being number 2, the middle child of the root being number 3 and the right being number 3. on the third level the left child node of the left child node of the root being number 5 and so on. if i have numbers 1 up to 13 and want to put each number into a node numbered the same i.e number 1 gets into the root node, number 2 gets into the left child node of the root and so on. how would i achieve that.
View 1 RepliesI have a program in C++, that is doing some calculations. I use a vector in C++ and resize the vector in the program, in order to conserve and allocate memory. Can you allocate memory in vb.net? So if my user inputs 1000, I want an array/vector to have a size of 1000. Can I change the size of the vector in the program? And is there a difference between container types in vb.net, I was just assuming
Dim xx(1 to 1000) as double, is the standard way of declaring.
And resize xx(1 to N) would be the way to resize.
I am using visual studio 2008 express.
I am working on a project where my forms resize to fill the users screen (which means they have different dimensions depending on screen resolution).I have made some vector images (.eps) in hopes of using them on my forms so that when the form opens the images always look clear, crisp, and not skewed.I am finding that vb.net will not let me import a .eps file into my resources. Is there a way around this? Is there another way to get a vector image into vb? possibly an SDK that will allow me to work with .eps files the same way i work with .dcm images?
