VS 2005 A Line Intersecting Rectangles?
Jun 20, 2010
I 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.

I am drawing an arc within a square or a polygon with the maximum possible radius inside.When the arc is drawn within the boundary of the square or polygon,the arc length will intersect at few points on the square or polygon.How to find the coordinates of the intersecting points of arc at the periphery of the square/ polygon?

just needed to get my head round something. Say I have a class 'myClass' with properties ID and Name. Now say I have 2 lists of objects of this type as follows:
Dim list1 as List(of myClass) = GetList1()
Dim list2 as List(of myClass) = GetList2()
What I want is to 'intersect' (this may not be the right word!) the two sets of data by the Name property, but bring back the ID property from list1. A suitable database analogy would be if list1 and list2 were tables, I'd want to do a left join from list1 to list2 on the Name field.

I am trying to create a LINQ query statement that retrieve intersecting data from 3 datatables (dt, dt1, dt2). My first attempt to do so with the following LINQ query statement was successful: [code] However in my design, I would need the LINQ query statement to be dynamically generated, because I want a user to be able to retrieve intersecting data entries from VARIABLE number of datatables. In this case, the first option is not as good as the "INTERSECT" query operator, with which I can just easily connect each SQL query statement with a "INTERSECT" operator. The problem is that my second attempt using the "intersect" operator fails, and after many trials and errors I still can't get it to work. [code]

In my space invaders game, you press start, which creates 15 pictureboxes. When I hit the spacebar, a bullet moves to the top of the screen. What code would allow me to make a picturebox invisible that isn't named yet?

I am trying to have different types of rectangles. I thought something like this would work, but Rectangle is not a class.
Public Class xRectangle
Inherits Rectangle
End Class
What I wanted this for was to remove a selection rectangle from an existing drawing. I have all of the objects to draw stored in a list and I am trying to remove the selection rectangle without removing the object it is covering.

I 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?

I just want to draw some lines between the rectangles in vb.net. I used g.drawstring() method to that.
But now, based on a value I just want to change the opacity of the arrow.

I 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.

Lets 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?

I have two rectangles; a character and a block. The character is suppose to jump onto the block and then either jump off it or walk off it. I am really getting frustrated with this because I cannot get it to work.

I 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.

My 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.

Redrawing rectangles on a Form? I have a problem repainting my form, I'm creating a "Bouncing block" Type of game , the Ball as a PicturBox, the Bar as A Picture Box And the Breakable "Targets" as An Array of Rectangles created in my forms Paint event using "e.Graphics.FillRectangles(Brush, rectsF)". It Looks a little like this:
Top of my Form(in the MainForm class):
Dim Brush As New SolidBrush(Color.Red)
Dim rectsF() As Rectangle

I have a DataGridView (not data bound, not editable) that displays a bunch of data. I want to draw rectangles around some of the blocks of cells to set them apart visually. For example, I want to draw a red border around the block of cells from row 3 colum 2 to row 6 column 3 so that there is a red rectangle around the 8 cells.I've found how to paint rectangles around individual cells or rows, but I can't work out how to do it for a block of cells.

I don't really know how to explain this except that I want to draw a bunch of rectangles in a LOOP, then I want each rectangle to be put into an array. To be more specific as alot of people keep telling me to be....I am making a robot, that can move left or right from below the screen, the robot is a rectangle with a barrel in the middle of it. The robot can shoot bullets, but as I understand I have to draw the bullets from the code. So far I have the functions written down to get started and I have tried all the drawing methods, and none of them will do what I want.
vb.net
Public Class Form1
Robot Settings

I'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.

I am able to get the lines to change their locations, but the dragHandle rectangles won't update - they stay at their starting locations. I would have thought since the points list changed the updateLinehandles() would fix it.

I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return?Going to try using /U or /A CMD switch next..

I want to be able to click and drag the mouse over the picturebox to create a selection area and I want it to snap an image to each place on the picturebox that it can. So if I have it set to snap to 50 pixels, and I select the points (50,50) - (100,100) I should get back 4 points: (50,50), (50,100), (100,50), and (100,100). The thing is though, It can't loop through every single location.

I 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.
