How To Find Angles Of LineShape Controls

May 9, 2012

I need a Function or section of code that finds the angle of a lineShape. Alternitively, a code to find the angle between two set coordinates would also work. I need to know the angle in order for my program to work properly. I'm using VB Express 2010.

Way To Do Collisions From All Angles

Aug 19, 2009

Well I attempted collision detection and it was only ok. First of all only the out of bounds place would work because I just made the right side of the screen make you go left etc.My moving button also goes outside of the area for a brief second before it teleports back to the bounds + 3 or w/e.Never mind all of that I guess.Could someone give me some source code for the simplest way to do collisions from all angles (like a zelda game or something...) or just up/down or left/right (like in pong).

Working With IntersectsWith And Angles?

Mar 9, 2011

I followed this tutorial [URL] in creating a pong game in VB NET, everything worked well as followed but believe there is still more development that needs to be done to it, for example if the ball is moving horizontally in a straight line, it will just re-bound of the paddles in the same angle everytime which means there is no point to the game. When the game starts moving the ball at a random angle and the ball re-bounds of either paddles, it will re-bound in the same angle it started with each time.

Pointed out what code this is:

Dim random As New Random() ' Random instance
Dim xVel As Single = Math.Cos(random.Next(6, 8)) * speed ' Move ball from randomized angle in X-axis
Dim yVel As Single = Math.Sin(random.Next(6, 8)) * speed ' Move ball from randomized angle in Y-axis

[code]....

If the ball hits the top of the paddle object, it should re-bound at a different angle How it should be is when the ball hits the paddle object, it should re-bound at a different angle, if it intersects at the top of the paddle, it should re-bound up or bottom of paddler should re-bound down.

C# - Bug In The Matrix.RotateAt Method For Certain Angles?

May 24, 2010

Here's the code i'm using to rotate:

Dim m As New System.Drawing.Drawing2D.Matrix
Dim size = image.Size
m.RotateAt(degreeAngle, New PointF(CSng(size.Width / 2), CSng(size.Height / 2)))
Dim temp As New Bitmap(600, 600, Imaging.PixelFormat.Format32bppPArgb)
Dim g As Graphics = Graphics.FromImage(temp)
g.Transform = m
g.DrawImage(image, 0, 0)

(1) Disposals removed for brevity.

(2) I test the code with a 200 x 200 rectangle.

(3) Size 600,600 it just an arbitrary large value that I know will fit the right and bottom sides of the rotated image for testing purposes.

(4) I know, with this code, the top and left edges will be clipped because I'm not transforming the orgin after the rotate.

The problem only occurs at certain angles:

(1) At 90, the right hand edge disappears completely.
(2) At 180, the right and bottom edges are there, but very faded.
(3) At 270, the bottom edge disappears completely.

Is this a known bug?If I manually rotate the corners an draw the image by specifying an output rectangle, I don't get the same problem - though it is slightly slower than using RotateAt.

How To Calculate Angles Of Right Triangle Given Lengths

Apr 5, 2011

I'm working on a Pythagorean Theorem program that calculates the sides and angles of a right triangle. I have the side measurements and all that down, but I can't find the Visual Basic function that will allow me to calculate the angles from the side measurements. I've tried asin and sinh, but both give me the wrong measure.

VS 2008 Recognizing The Pixel Angles?

Aug 20, 2010

Im making a little game. All it does is make a bunch of Random Letters. Move around the screen. Im drawing to the form with paint. But i wanted to make it. So you have to click the letter that my program ask's you to click. I know there is easy ways of doing this. Like just getting the x,y and the mouse x,y on the click event. But i was wondering. If i could accomplish this task. Just by Scanning about 10x10 pixels from where the mouse down event is triggerd. to see if a letter is there. And how i could make it see if it is an A or B etc. The font is white. And about this size. I was thinking about it counting all the white pixel's but that wouldn't work?

.net - Remove Selected LineShape Shadow Effect?

Mar 23, 2010

Is there a way to remove the LineShape shadow effect when selecting the lineShape? I tried

Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
Dim g As Graphics = e.Graphics
g.SmoothingMode = SmoothingMode.AntiAlias
Dim oldmode As SmoothingMode = g.SmoothingMode
g.DrawLine(_Pen, X1, Y1, X2, Y2)
g.SmoothingMode = oldmode
End Sub

but finally, this have some back effects on invalidation: when moving (in a panel) the line leave traces - does not invalidate properly.

VS 2008 - LineShape Control - Cannot Select Text Boxes

Aug 8, 2011

I am facing an important problem with the LineShape control (installed with the Visual Basic Power Pack) . The problem is that in design time once I have "Sent to back" some controls (other controls, like text boxes), I can no longer select them! The controls get stuck on the form and I can't select them anymore! Even if I select those controls from the Properties window, I still can't do anything with them (like move them over the form etc). Right now I am using VS 2008. However maybe this problems doesn't appear on VS 2010?

VS 2008 - Windows Forms Designer Lineshape Echo Artifact

Feb 10, 2009

In a windows forms class in Visual Basic 2008, there are several horizontal lines created with the lineshape control dragged from the toolbox. A very strange thing is happening with the horizontal lines. In the forms designer, all of the the lines (both horizontal and vertical) look fine, but when the program is executed (in debug mode), about 3 seconds after painting the screen nicely, I get echos of portions of the horizontal lines about 50px or so above my horizontal lines. You can look at the screenshot here: [URL]

Can't Seem To Find Anyway To Adjust The Volume Controls?

Sep 15, 2009

I've been digging around but I can't seem to find anyway to adjust the volume controls (the windows general ones) using VB .NET.Basically, I want to make a program that's always on top that allows me to changemute the microphone and the other volume values on a specific device - not necessarily the one set as default.

I got this weird feeling that I'm missing something quite simple but I simply could not find anything. I saw some media players and such but nothing similar to what I was looking for.
