VS 2010 Draw A Line And Calculate The Angle?
Oct 20, 2011
I Have created a program (see below) that enables you to use you cam. You then draw a line and calculate the angle. The purpose is that I do alot of work with remote control cars and need to acuratley set toe and camber angles, it takes to long with the "old" method So I am creating this little program. ok, so, lets see what I want to do. Well, the first thing I would like to do is draw a line from top to bottom of my picture box dead center of left to right, this is dead center of the cam so the bottom of your item should be posistioned to meet the bottom of the centre line. I then draw a line from bottom to top of the objects angle. I then use the dead center line and the line I drew to calculate the angle.

I 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?

Ok. So I have a program I have made to calculate angles. i have a line for true vertical and I need the program to draw the line at a given angle. Basically, if I put 82 in textbox1, I want the program to calculate the cordinates where that line sits on the X axis, The y axis is always picturebox1.height, So the y axis isn't important here, just the x axis.
What would I do to calculate this angle into a visual graphic?

if i use
Dim Gr As Graphics = SomePanel.CreateGraphics()
Gr.Drawline(StartingPoint, EndingPoint)
I want to be able to have a line drawn from point a to b, but be able to rate it 90 degress based on user input so if the user inputs 70 I want it to rotate 30 degree's to simulate a 70 deg relationship to a horizontal line that it touches if that makes any sense. a is starting point b is the user inputs 70 and it draws it at 70 in relationship to the horizontal lineheres the image that i forgot to post above Attached image(s)

i am trying to get the angle of a line in relation to the x axis. The line is being drawn in a picturebox. So its the Upper right quadrant of the cartesian plane ... but its flipped over the x axis.im using this code
a=pt(1).x
b=pt(1).y
c=pt(2).x
d=pt(2).y
z=math.atan2((c-a),(d-b))*(180/math.pi)
The issue is that the line im drawing is almost parallel to the x axis but its returning a value of roughly 90 degrees .It seems like it is giving me the angle in relation to the y axis, but not being super good at the math myself im not exactly sure what to change here.

I am currently drawing a line with Graphics. Drawline. Once this is drawn, under certain circumstances I want to change the colour of it. When the line is drawn, does it become an object that I can then refer, or do I simply draw a new line over the original in a different colour

For class, I am creating a Tic Tac Toe game. When there is a win I would like to draw a line over the 3-in-a-row. Not sure if this is possible because I used an array of buttons to represent the X's and O's. If this is not possible I would like to highlight the winning buttons.

I need to draw a line on a series of pictures: I have decompiled a movie file to 1200 pictures. I also have 1200 samples of vector data (coordinates of the line: beginning point, ending point , size of vector (length) and direction (angle)... anything). With these data I want for each corresponding picture to draw a line corresponding to this vector data for instance: picture 550 needs to get a line drawn from point (5,95) ... these are (x,y) coordinates. in direction of 5 degrees from a vertical line and length 55. Visual Basic do that? I understand there will be some work in locating the origin of the x,y coordinate system and telling the program what 'size 1' means...

I want to move cursor with visual basic and it seems I found way how to do that. It is possible even click with Visual Basic whereever on screen. But I cannot check out where on the screen the click was done and so I want to draw two short crossing lines on that point as marker where Visual Basic clicked on screen. If it is possible to move cursor to that position and show it then it is as good as drawing marker.

I seem to have great difficulty in creating a draw pen line function whereby the user clicks a button to create a line then picks a point on the form and types in a length in a textbox, which will also become the length of the line, its self.

I am trying to find some algorithms or formulas for doing a fillet or blend operation on the intersection of an arc and a line segment given a particular radius. In other words, I need to find the equation for the circle that will have tangent points on both the line and the arc. Eventually, this has to be calculated using VB.Net

I have a borderless form that I'm "docking" onto the top edge of my screen. Inside of the form, I'm placing a single toolstrip control, which docks across the entire form -> (picture the taskbar to get an idea of what I'm talking about).Because the borderless form has no edge to it, I wanted to draw a black line along the bottom edg` of the form to differentiate the form from the windows or desktop behind it.
The problem that I'm facing is that`the toolstrip will not move "behind" the line when it's docked, no matter how I order the control layers.
I've tried programatically sending the control to back to no avail either.
Any ideas on how to get the line to show above the docked toolstrip?
