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 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?

Object Oriented Programing, Where To Draw The Line?

Jul 10, 2011

I created a project in Excel-VBA (wich I'm also new at) that connect to a SQL. It retrieves data, puts it in arrays, calculates, writes it up nicely and mails it to a mailing list before it closes itself down. This works when Excel is stable on the server, which it is not. Therefore I'm set on rewriting it to VB.NET (just have to learn it first).Project:To build this project in VB.NET I wanted to try and make it Object Oriented (OO). I have read that OO is when I create a Sub or Module for different tasks. Are there any advantages in learning/doing this from the start? I plan on creating Subs for almost everything, and then call it from a Main sub.

Too much OO?:
These are the modules I plan to create (and call)
