Graphics: Picturebox Intersect With Lines?
May 25, 2011There's this form with many random lines connected to one another using
Me.CreateGraphics.DrawLines(Pens.Black, pointsArray)
There's also a Picturebox that can be moved using the arrow keys...
I want a messagebox to show when the picturebox overlaps/intersects with the lines.
How can I do this?
Intersect Extension Method, Case Sensitivity Not Working
Jan 18, 2010I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.

Have Different Types Of Rectangles?

View 5 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?

Draw Rectangles To Make A Map File?
Dec 11, 2009I have an automated electrical tester, I want to create a type of map file so that way the user can select a subset of devices to test. So basically I want to create a type of grid that the user will be able to highlight specific rectangles in the grid so that way the tester knows to test only those specific locations. To start I want to create a 4X4 grid and each individual rectangle in the grid will contain some coordinate information. Does anyone have a tiny example of how I can draw a 4X4 grid, or any thoughts on the best way to do this? The real final map I will be making will have over 50K devices.
View 1 RepliesDrawing PolygonHotSpot Coordinates Around Two Rectangles?
Feb 2, 2011Lets say that I've got the coordinates of two Rectangles, they could be right next to each other or have space between them. I need to draw a PolygonHotSpot around the two rectangles (so it will only cover the two rectangles and the space between them). I've come to find that I have to give the coordinates a clockwise order around the entire polygon, rather than around each rectangle (which works fine for a single rectangle).
So given a list of coordinates, is there a way to get them into the order that I need for there to not be any gaps in my PolygonHotSpot?

Jun 20, 2010I have a bunch of rectangles simulating players for a football game I'm designing. I want to find out how many "players" are in between two points on the field. I have a start point (a defender trying to locate the ball carrier) and endpoint (the ball carrier). I need the number of other players in between those two points (I have all of their coordinates as well). The more traffic in the defender's field of vision the harder it will be to find the ball.

View 9 RepliesCalculating Physics - Rigid Body Rectangles
Apr 13, 2010I need some help calculating physics after a collision, sort of like rigid body physics but just for rectangles, I don't need them to rotate but only to know the x and y speed they leave each other and the angular velocity etc. the collision with the walls work fine since all I'm doing is reversing the speeds of the rectangles (which is probably the wrong way of doing it) but unfortunately this does not not work for the two rectangles colliding with each other, so can some1 lead me in the right direction as to how I can go about calculating this.
View 7 RepliesDraw Single Pixels And Rectangles On Any Web Browser?
Nov 17, 2010My aim is to draw single pixels and rectangles on any web browser.
I ve been thinking alot about this and I think I that there might be 2 ways to do this:
1) Send message api maybe?
2) Direct 3d hook with C++ (Although this is quite complicated)
So my questions are:
Btw the use for it is to detect a certain pixel on the webbrowser and draw on it.
Don't ask why since it is quite complicated and I know also how to use Send message api and I once managed to program a direct 3d hook (but for a 3d game which was based on direct x SDK) with C++ although im not sure if it will work due to webbrowsers dont work with directx.

Find Total Overlap Percent Of Multiple Rectangles ?
Jun 19, 2012I've got a list of System.Drawing.RectangleF objects that all overlap the same RectangleF object.In my picture below, the 3 overlapping rectangles would be the pink, yellow, and red rectangles.My main rectangle in question is the light blue rectangle.
Second Image: I know that with RectangleF objects I can use the Intersect() method that will return me another RectangleF object representing the overlap. But as far as I can tell, this only really works when comparing two rectangles.
My question is: How could I determine the TOTAL area/percentage (i.e. the combined total overlap of the red, yellow, and pink rectangles when compared to the light blue rectangle - but it would need to be smart enough to not count the area in which the red and yellow overlaps twice, and same for the pink and yellow)?
NOTE: The green lines represent the area I'm looking for, just the total area of the blue rectangle that is not visible.
UPDATE: I've added a 2nd image to further demonstrate what I'm looking for. In the second image, the presence of the burgundy rectangle should have no affect on the total percent covered because that area is already covered by the yellow and green rectangles.

Apr 20, 2012I would like to draw a rectangle on a form, for example to mimic a steel beam that is 6 metres long.Within this rectangle, there may be 4 "openings" or circles that mimic a diameter of 600mm, so i need to draw 4 circles within the rectangle, to indicate a beam that has 4 openings. Other issues I need to cater for is that one of the circles may not be in the centre, it may be slightly raised.The user can change the length of the beam and the size of the openings so i'd like to refresh my drawing to keep in line with this.
