Draw Rectangle In A Circle?

Mar 12, 2011

User launches the application, enters width of circle, then enters width and height of rectangle and presses the button. Then app draws the circle with rectangle inside of it (if it fits). App should output the coordinates x1;y1 , x1;y2 , x2;y1 , x2;y2 (corners of rectangle) somewhere on form and would be great if it could post those coordinates on x and y axes (optional).

Use Timer To Draw Circle / Path?

Mar 17, 2009

I need to write some code which draws a predefined circular path (say 48pix diameter) and use a timer to delay it to show it being drawn. I need to use GDI+ to do this. My guess is on the Timer.Tick, I would set some Point value for the next point on the path, and then call Invalidate to raise the Paint event.

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)
Radius = 10

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 An Accurate Circle With MouseDown And MouseUp Boundaries?

Dec 30, 2008

is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...

Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?

Draw Ishihara-transformations (circles In Circle Without Intersection)?

Apr 28, 2011

Question: I need to draw pictures as below in C#/VB.NET Draw ishihara-transformations (circles in circle without intersection)?

Note that my problem is NOT drawing circles in C#.

My problems is drawing them without much whitespace and without intersection.

My thought would be using "Orbits" and then draw the circles with center on the "orbit" lines. (with some orbit lines for bigger and some only for smaller circles)

Synchronising Clock With System Clock?

Mar 12, 2009

I'm a totally newb to VB and I want to do this. I want to do display system clock into a textbox. The trick is that I want it to be synchronized with the Windows XP clock. I want to have something like +/- 100 ms accuracy.

Each 'second' change will trigger an output pin to ground into the parallel port. This is very important that the 'second' change in the same time the Windows XP second change. Do not care about the parallel output thing, I'm nearly there. My main concern is the synchronisation with Windows clock.

In my code, I've added a counter that increment +1 at each 'second' change. So, when the 'n' value will reach a determined value, it will trigger another event.

[Code]...

I searched on the net and I found a thing about NIST time server.. Maybe this could be an otpion, but I have even no idea about how using it... I'm a total newb, but I'm ready to learn. So, please use simple language, no hard to understand acronym etc.

Change Colour Of Circle?

Nov 5, 2011

I have created a program that Draw a circle and then you can move it around a picturebox. I have made code so that it changes colour but instead of changing the colour of the circle already been drawn it creates a new circle which when you overlap the original circle with the new circle it cuts part of it.So what I wanted it to do when I change the colour of the circle it changes the colour of the circle already been drawn instead of creating a new circle.

[Code]...

Also I can't use the X and Y coordinate input to move the circle to the entered coordinates.

Display Circle That Follows Cursor ?

Jun 9, 2011

I am making a whiteboard program. So far I managed to generate the ability to draw lines and other small things. The problem is that I want to make a circle that follows the cursor to display what a dot there would look like. I am aware of the creategraphics property of picture boxes, but when I do that the circle stays there and a new one is generated where the mouse is now (an expected result). My question is, is there a way to draw and delete circles as the mouse moves. Also, is there a more efficient way of doing this. I did try using the OvalShape found in the power pack, but I cannot figure out how to display that over the picture box, when I right click the oval nothing happens.

Make The Circle Bigger By +1 Til = To 55?

Feb 8, 2011

I am trying to do a do while loop to make a circle draw itself resized by 1 each time 50 times. I just dont know how to define the numbers that make up the circle size properties. here is my simple code

Me.CreateGraphics.DrawEllipse(pencolor, 135, 125, 5, 5)

I would like to just make a simple do while loop to adjust the 5,5 by +1. I am really new to programming and any help will be excelent. If I knew the property name of the 2 numbers I need to change I could declare them as a letter H & W and just do while

H,W is < 56
H+1
W+1

if this makes any sense?
