## Interface And Graphics :: Draw A Circle On The Console?

Feb 28, 2012

I am trying to draw a circle on the visual basic console. I have been told that the console is not made for this but i have to use it.

What I want to do is a circle with:

Centre (40,20)

I know from basic trig that the following will give me the points on the circle:

x= (10 x CosA)+40
y=(10 x SinA) +20
(A) being an angle in radians.

Then combine x & y that will give me a point on the circle.

I want to use the '' Sets the cursor position

Console.SetCursorPosition(x, y)
Console.Write(".") "

To print a point(.) on the given position from the formulas above.

Now heres my question how do I get Visual Basic too calculate:

x= (10 x CosA)+40
y=(10 x SinA) +20

360 times i.e 0rad-2Pirad and then pass the x & y [(x,y)] point to my cursor position code so that a '.' is printed at that position. I.e I will end up with a circle made out of 360 '.'

I would asume that a loop is used and also an array to store the 360 Pi values. I'm finding it extremely hard to even get Vb to calculate the Cos of an angle.

## Draw A Line On A Picture?

Jun 29, 2009

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...

## Draw A Line Above A Docked Control?

Nov 9, 2011

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?
