I have two points (x1, y1) and (x2,y2) and have a straight line between the 2 points, from this I can work out the distance between the 2 points lets say it is 50.What I want to do is increase or decrease the length of the line by a predefined amount lets say 10.So If I increase the line length by 10 (from 50 to 60), What I want to work out is what point(x3,y3) would be at the end of the increased line.Hope this makes sense.I have tried to work out the new point using the angle but it does not work correctly, it does not seems to produce a perfectly straight line and the angle from point (x1,y1) to the new (x3,y3) is not the same as the angle from point (x1,y1 to x2,y2).
This is what I have tried:
:I work out the angle
aAngle =Math.Atan((Y2 Y1) / (X2 X2))

View 2 RepliesI 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...

I want to move cursor with visual basic and it seems I found way how to do that. It is possible even click with Visual Basic whereever on screen. But I cannot check out where on the screen the click was done and so I want to draw two short crossing lines on that point as marker where Visual Basic clicked on screen. If it is possible to move cursor to that position and show it then it is as good as drawing marker.

I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.

In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.
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?

The corresponding method for the paint event works fine in a panel, but the picture box doesn't seem to support it. What am I doing wrong?
