I'm sure some of you know the equation to get the distance of 2 points on a coordinate grid, and I'm making a program to do just that, the only problem is that when I use the square root function it doesn't return an exact number, what's wrong with my code?[code]...

i am having a problem in building up a VBcode for getting the minimum distance between a set of coordinate points. what actually i an trying is to find the minimum distance between one set of coordinate points(A(x1,y1),Bx2,y2),C(x3,y3),D(x4,y4),E(x5,y5)) with respect to another set of CO-ord points (i(x1,y1),j(x2,y2),k(x3,y3),l(x4,y4),m(x5,y5))..

the above is code which i have created till now and the next step is calculating the mindistance criteria..search criteria . rear points is the one we get frm solidworks and b.rearpoints is the one present in database we compare both of them find the one which is very similar to the one in database..

View 5 RepliesI would like to get 3 point coordinates on mouse clicks and get them display in the text boxes. I'm working with my project. An image will be loaded in a picture box and the image has 3 reference point. I need all the points coordinate to be display separately whenever user click on the points. When user click on the first point, the coordinate of the point will be display as point a, click on the second point,the coordinate will be display as point b, and click on the third point,the coordinate will be display as point c.
View 4 RepliesI'm using Visual Basic 2006 and i'm a newbie so excuse me if my question is not complete. I basically have a picturebox, in which i am displaying an image from a webcam. Now the user clicks on two points on the image and i need to get the distance between the two points in terms of the number of pixels. I did think of and try the pythagorean theorem, but i'm confused as to what units the answer turns out in. Is it in terms of inches? or pixels? Do i need to set the Scale Mode propety to pixels to get it in pixels? And if so, is there a way to get the number of pixels per inch? Sorry for asking so many questions but i've been reading other forums and i'm confused!
View 12 RepliesThis project is based on a MUD, or at least originates from playing them. I have an ascii map where each character represents a type of terrain. I have found code for reading one line at a time, but I need to not only dictate which line to be read, but how many characters in to the line to read. Basically trying to make a grid/coordinate system, where I can tell it my location is 4, 7 and the program will read the fourth line, seventh character.

View 4 RepliesI am currently making a 2d game where a spaceship flies around a 2d map.Currently, I am moving the ship with keys, but would like to implement mouse clicking as well.I am wanting to enter an x and y coordinate and have the ship move to that coordinate.
These are my variables:
PlayerFacingAngle, PlayerPositionX, PlayerPositionY, PlayerVelocityX and PlayerVelocityY
You could check to see if the distance across the form minus the distance across the picture box is equal to the horizontal location of the picture box to see if it's on the right side. For the left side, just check if the horizontal location of the picture box is 0.

View 4 Repliesassuming i have an isoceles triangle, where i know the height + base width, how
can i calculate the width of that triangle at 1/3 of the distance from the point + 2/3 of the distance from the point?
i thought it'd be simply 1/3 base width + 2/3 base width, but my drawing is +/- a few pixels when i resize it?

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

View 8 RepliesI can't get a simple answer to this. I have pixel coordinates, I want to print an image in a (landscape) page at those coords.In my printing event I do:
Dim mypoint As New PointF(1, 1192)e.Graphics.DrawImage(My.Resources.littleSquare, mypoint)
This obviously doesn't work: I specify pixels but the driver expects inches(?) or what?
Tried to: e.Graphics.PageUnit = GraphicsUnit.Inch with no luck.I'd like a conversion method like:
