Identify Subtriangle Within A Rectangle Given A Coordinate In That Rectangle?
Feb 22, 2010Given 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?

Collection And Picturebox Intersection?
Jan 8, 2009(VB 2008) ok im making space invaders for a midterm project, that is i made space invaders and then lost my thumb drive, WITHOUT BACKING UP ANY OF MY PROJECTS. point is its due tomorrow and im having trouble with one of my methods. i have a collection that stores all the missles the enemy shoots, then i have a collection that stores each picture box that makes up the barriers. my method is supposed to search thro both collections and check to see if they intersect. if they are both visible they become invisible creating an illusion that they dissappear. i hav organized the rest of my code to ignore the missles and barriers if they are invisible but this part isnt working for some reason.

Graphicspath And Line Intersection?
Mar 17, 2010This is my problem...I have created graphicspaths (gp) in Visual Basic...but every gp has a name. So I want to print every name next to the gp. I use GetBounds to get the nearest rectangle around the gp. But like for a circle the name will be quite far away from the gp. Now I want to draw a line from the name to the outline of the gp...can somebody help me with this little part of script?
View 11 RepliesAny Way Can Check Intersection Between Any Two OBJECTS Not Just Rectangles?
Feb 11, 2012I have made considerable progress on a game I am making, but one of the fundamentals of it relies on collision detection. At the moment, I am using Rectangle.IntersectsWith() to check "collision" between two PictureBoxes, but I don't want everything all square (graphics, etc). So I set about adjusting regions and have ended up with a circular button (from the MSDN example). What I'd like to know is this: Is there any way I can check intersection between any two OBJECTS, not just rectangles? As in, if the rectangle intersects with or is inside the circle in any way then how do I check it programmatically?
View 3 RepliesNunit Assertion For An Empty Intersection Between Collection
Dec 21, 2010I have a list of user names (we'll call 'original list') one object is returning. I have a list of user names (we'll call 'filtration list') another object is returning. I am testing a method that returns all of the items from the original list not in the filtration list. Ideally what I want is something like:
Assert.That(returnedList, Has.No.Members.In(filtrationList))
So far the only thing I can do is iterate over the filtrationList and do
Assert.That(returnedList, Has.None.EqualTo(filteredUser))

View 10 RepliesDraw Ishihara-transformations (circles In Circle Without Intersection)?
Apr 28, 2011Question: I need to draw pictures as below in C#/VB.NET Draw ishihara-transformations (circles in circle without intersection)?
Note that my problem is NOT drawing circles in C#.
My problems is drawing them without much whitespace and without intersection.
My thought would be using "Orbits" and then draw the circles with center on the "orbit" lines. (with some orbit lines for bigger and some only for smaller circles)
Find Line Intersection Point With A Grid Of Lines?
Jun 4, 2009I am suing VB 2008 express edition.
I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.
[URL]
In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.
How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
C# - Built-in Types When (not) To Use?
May 26, 2009C# and VB.NET comes with built in types that maps to the CLR types. Examples are: int (C#) and Integer (VB) maps to System.Int32, long (C#) and Long (VB) maps to System.Int64. What are the best practices for deciding when to use built in types or not to use them (using the System.* structs/classes instead)?

Add Built-in Constants To Program?
Jul 30, 2010It would be good if visual basic had standard math constants like pi, the Euler number, and others built-in so one doesn't have to define them each time and have the possibility of making typos. Even some of the physical constants in MKS unit could be included like the Boltzmann's Constant, speed of light, permittivity and such. Each could be a special simple like kb for the Boltzmann's constant. Or it could be a properties like phyconst.c for the speed of light, phyconst.kb for the Boltzmann's, phyconst.sb for the steffan-Boltzmann's constant, pmathconst.e for e=2.71.

Button Not Appearing When App Built?
Nov 3, 2011I have a problem where a button at the top left of a tab control will not appear in debug or compiled. There is no code telling it to hide.
Now, I can make it re-appear by moving it, then moving it back to the exact same position. If I then re-build it will be there.
It will then be there for a number of builds, at which point it might disappear again. This seems to happen for a few buttons in my project. The common factors are that they are on a tab control (standard dot net ctrl) and near the top left of a tab page.

May 14, 2010i have an application that's in development, but some modules of the application are already built, so the application it's installed in several computers. In my code, i call an external class that i built with several functions that i use in multiple applications, in this class i have a small piece of code that checks in the network (internal), if a new version of the application (Msi File), of the current application it's available, and if it's available, it runs the Msi file.
msiexec /package MSIPackage.msi That worked fine in windows XP, but now some machines have been upgraded to windows 7, and the user need other credentials to run the package. (Elevate Privileges). Other problem it's that in my application i create several folders in the installation and the user doesn't get any permissions to write in the folders.For example i have one Log folder, and i can't write any logs to it.
