Draw Rectangles To Make A Map File?
Dec 11, 2009
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.

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.

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

I was able to make a program that can draw on a form but if I draw very fast, the lines are cut. Check image below :
Another is I want to make my form be able to load a power point presentation. Is it possible? Also, I was wondering if it is possible to save the form as image file like what we do in screenshot?

I am about to make a simple Raffle Draw System.I can display the random ID's of participants, but what I really wanted to achieve is that the names are the ones to be displayed randomly..
Say when a user click the button, using a timer a certain label will randomly display names of participants from the database and by such time that he stop the timer, the name of the winner will eventually shown.[code]...

Subject A |_______|________|________ | Subject B |_______|_________________| Subject C |_______|________|________ | Subject D |_______|_________________| Subject E |_______|____Total__|________ |
there can be different number of rows at the left side,meaning it depends on output of the query.And heres the problem, i need to make another table at the right side. how to make a table at the right side or draw lines without affecting details section? this is just purely table without fields on it.

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.

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 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 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 to get the DataGridView to perform the way it should perform. I'm new to the .NET environment, but I learn fairly quickly. However, I find it difficult to decipher themassive black box of the DataGridView control enough to make it do anything other than what it already does--Draw very slowly.

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.

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'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.
