VS 2010 - Draw A Straight Line Between Two Points And Calculate The Length Of That Line?
Jan 3, 2012I have a picture in my picturebox. In that picture, I need to draw a straight line between two points and calculate the length of that line (probably in pixels). Is there any suggestion how to do it?

the 2 points either side of the centre points
are +/- width or height * 0.2761423749154
i have 4 known points, topLeft, topRight, bottomRight, + bottomLeft.
the polygon won't always be a regular rectangle as it is in the image

View 3 RepliesUsing As A Straight 'finishing Line'?
Jan 24, 2010I have a line shape which I am using as a straight 'finishing line'. As the program runs an identically shaped line shape appears. I am a little confused from where and how it is appearing, as I only have the one line shape. Also, on some runs of the program 'trails' of the cars that are racing across the screen remain.Are these issues something simple I can fix?
View 5 RepliesWorking Out The Point Positions Along A Straight Line?
Jul 22, 2010I have two points (x1, y1) and (x2,y2) and have a straight line between the 2 points, from this I can work out the distance between the 2 points lets say it is 50.What I want to do is increase or decrease the length of the line by a predefined amount lets say 10.So If I increase the line length by 10 (from 50 to 60), What I want to work out is what point(x3,y3) would be at the end of the increased line.Hope this makes sense.I have tried to work out the new point using the angle but it does not work correctly, it does not seems to produce a perfectly straight line and the angle from point (x1,y1) to the new (x3,y3) is not the same as the angle from point (x1,y1 to x2,y2).
This is what I have tried:
:I work out the angle
aAngle =Math.Atan((Y2 Y1) / (X2 X2))

Aug 16, 2010Under the MouseLeftButtonUp event handker store the first coordinates of the lines second endpoint. Then call the length method to obtain the distance between the two endpoints(the lines length). Fianlly display the line on the canvas and the line's length in the Length=Label. Below is the code I have so far. There are no errors, but when I run the application nothing happens.

VS 2008 Depreciation Loop - Calculate Straight-line Depreciation (cost * 1/n) N Being The Number Of Years To Depreciate
Jul 25, 2010I have a program where I have to calculate straight-line depreciation (cost * 1/n) n being the number of years to depreciate, and Double-Declining depreciation (cost * 2/n) using user input for year of purchase, cost, and years of depreciation. The output needs to be put into 4 columns in a list box. Year, Value at beginning of year, Amount of depreciation during the year and Total depreciation to the end of the year.
The problem I am having is with my loop. It is not properly calculating. I'm sure I am doing something wrong that is simple, but I can't see it.
Here is my code; the problem areas are bold:
Public Class frmDepreciation
Dim Cost, Life, Year, Depreciation, BegValue, EndValue, Total, Counter As Double
Dim fmtStr As String = "{0,-10}{1,10}{2,17}{3,5}{4,-15}"
Dim fmtStr2 As String = "{0,-10}{1,10}{2,17}{3,15}"

Drawing A Line With Points?
May 13, 2009I have a question about drawing lines. Most of the code snippets I've seen approach drawing a line with the mouse down as the startpoint and the mouse up as the endpoint. But I am trying to draw a line by startpoint as
a mouse click and then an endpoint as a mouse click just as you do on a typical cad program.

View 1 RepliesVS 2008 Calculate Points On Line?
Feb 23, 2012Using the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.
' Xc = 1965
' Xp = 0
' Yc = 5244

Functions To Draw Line Or Move To Points
Jul 19, 2009Currently there are functions to draw line or move to points, commonly known as LineTo(x,y) of MoveTo(x,y). I am wondering if there is also a LineTO or MoveTo function(s) for 3D, i.e. LineTo(x,y,z) or MoveTo(x,y,z).
View 1 RepliesVS 2008 : Microsecond Timer To Plot Points On Line?
Feb 27, 2012A couple of options seem to be available to achieve better accuracy and shorter periods than the Timer control in VB allows, however they too seem to have their own unique drawbacks. I am trying to plot (draw) points that are calculated in my VB application and then represent them in real time with an accuracy of a couple percent. If VB can calculate the points in the microsecond time range, would it be reasonable to hang an external pulse source on a usb port and use the "Datachanged" event to count the pulses that will be summed and used to plot the points?Ultimately, this is a machine control application that requires "reasonably precise" timing - ie. CNC type control. The points are scaled and drawn and then step and direction signals are sent out through another USB port.

Apr 4, 2010I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"
