Change Pictureboxes X2 Y2 To Tilt Some Degrees Other Than 90 Degree Angles?
Jan 15, 2011I dont even know if you can do this in vb.net but, how do you change the pictureboxes x2 y2 to tilt some degrees other than 90 degree angles?

Detect Mouse Wheel Tilt?
Jul 5, 2009To detect rotation of the mouse wheel in .NET/WinForms, I can override OnMouseWheel. Clicking can be detected by overriding OnMouseDown (it's just the Middle button). But how do I detect tilting of the wheel (tilt to the left/right for horizontal scrolling)? Neither OnMouseWheel, not OnMouseDown is being called when I tilt the mouse wheel.

View 2 Replies.net - Make Mouse Tilt Horizontal Scrolling Always Repeat?
Jun 12, 2012I'm designing a form with a horizontal scroll bar docked at the bottom. I wanted to add support for side-scrolling using mouse tilt buttons and found this solution which, after a bit of tinkering, seemed to do the trick - that is, while the form only had GDI graphics drawn on its surface.
However, since then I've added some controls to the form and found that when the mouse is over any of them the tilt operation only fires once-at-a-time instead of repeatedly as it does when the mouse is over any other part of the form.To see what I mean (if you have a mouse with tilt buttons) dock a horizontal scrollbar onto the bottom of a form, add a few other controls and paste in this code:
Public Class Form1
Const WM_MOUSEHWHEEL As Integer = &H20E
Protected Overrides Sub WndProc(ByRef m As Message)
[code]....
You'll see that side-scrolling repeats when the mouse is over a blank part of the form, but only "one-shots" when it's over a control.I'm guessing the solution lies somewhere in the message's .Result value, but I'm at a loss as to what that should be. In fact I'm not even sure I'm returning a correct value anyway because the code in the original solution threw an exception to the DirectCast function so I swapped that for CType, which seemed to work okay. I've tried working it out using Spy++ but I can't see anything obvious.
UPDATE:I've noticed when I include 'Child' windows in Spy++ there are two (0x020E) messages and two return values, 1 then 0. I presume the message is being passed onto the control by the form. So I guess the question now is: can the message be prevented from being passed to the control? Or can the control's return value be intercepted and converted to 1?
Way To Do Collisions From All Angles
Aug 19, 2009Well 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).

View 37 RepliesWorking With IntersectsWith And Angles?
Mar 9, 2011I 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, 2010Here'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, 2011I'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.

Aug 20, 2010Im 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?

View 10 RepliesCompare The Degree Of Similarity Between Two Or More Images?
Jun 15, 2011I am capturing images from a webcam and I have to compare the degree of similarity between two or more images. that is... which two images are the closest match.
I know I cannot compare the pixels...so how do i go about it?
I am using Visual basic 2010 on Win7
This comparison need to be sufficiently fast. Within 2-3 seconds.
I was looking into pixel by pixel comparison. but webcam pictures as I understand do have slight changes between frames(disturbances).
I am working on recognizing hand gestures...which would in turn control a small mechanical crane...
for example a thumbs-up sign would mean a signal for crane to be switched on...and a full palm shown would mean a stop your work sign.
I plan wearing a white glove against a black background.
I also have ideas like dividing the screen into a 10x10 matrix.
