Calculation Of Minimum Distance Between Coordinate Points?
Apr 12, 2012
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))..
ublic Function DoSearch(ByVal SearchCritera As Bracket, ByVal ListToSearchFrom As System.Collections.Generic.List(Of TRacksDefinitions.Racks.Bracket)) As System.Collections.Generic.List(Of TRacksDefinitions.Search.SearchBracket) Implements TRacksDefinitions.Search.ISearch.DoSearch
[code]....
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..

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]...

code that creates a program where a user can key in 3 coordinate points and when the click "Generate Triangle" button. the program automatically creates the program.

I 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.

I'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!

I am using the following code to get distance between two propertys. The problem i am having is each Distance Calculation is being obliterated and I am only geting back the last Calculation instead of each calculation/distance

I 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.

assuming 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?

I'm using Visual Studio and table adapters using an Access DB as the backend. I need the minimum 4 digit value. I want to get next available 4 or 5 digit number. And this will change depending upon the users request. Currently I use a table adabpter query. But how would I write a query. I suppose I could do a long iterative loop through all values until I see a 4 digit.But I'm trying to think of something more efficient.
Function GetNextAvailableNumber(NumofDigits) as Long

I 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:
Dim mypoint As New PointF(convertPixelsIntoInches(1), convertPixelsIntoInches(1192))
e.Graphics.DrawImage(My.Resources.littleSquare, mypoint)Private Function convertPixelsIntoInches(ByVal pixels As Integer) As Single

I've got a map of the country I reside in and have all the railroad stations marked out. i've got all the co ordinates for each station and distances from one station to another.My question is what would the best way be to get the shortest distance between two stations, keeping in mind that one station may run through many others and there is more than one way to get there. See pic attached

I have a chart on a Windows Form with several line graphs. I would like to be able to get the x-coordinate from a mouse click on the chart in such a way that the user would be able to place vertical annotations on the chart at the location of the click. I looked at the Chart.HitTest function, but that will only do what I need if the user clicks on a data point, not anywhere in the chart area.

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
Label5.Text = "X:" & e.X
Label6.Text = "Y:" & e.Y
End Sub
Dim objectrect As Rectangle = rects(0)
Dim object_x As Integer = objectrect.X
Dim object_y As Integer = objectrect.Y
Label7.Text = object_x
Label8.Text = object_y
I discovered that these labels are not the same, the mouse move is more accurate. My mouse is currently pointing at the upper left corner of rectangular.
