I'm creating a movable scenary with, like 100 different flights. I want to create for every type of flight a triangle...so it's moves around and you have an idea how the airspace looksq like at what moment.Now my question is, what's the best way to draw these rectangles? I created a class 'Flight' and it has a Graphicspath in it. Now I want to update the triangle, which represents the aircraft, with the speed and heading...so it moves around well.

View 1 RepliesI am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees()
NumberOfTrees = Int(Rnd() * 10) + 15
For i = 0 To NumberOfTrees - 1

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.

I'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]

For this program I'll need a timer to stop at a random time interval, say somewhere between 3 and 10 seconds. Anyone know of a technique to do this.

I have the outline of a triangle right where I want it. I need to fill it so it's a solid color. Can anyone give me a start on filling it? (Using VB.NET 2008)
Currently working on a 2D engine, not for gaming but for design software / visualisation for machines. So far it is comming along quite fine. I started to wonder if it were possible to draw a triangle and fill it with some form of a a texture, or even better a polygon and fill that with a texture.
I know that DX can do that for me :P but I am realy focussing on GDI+ at the moment.

View 4 Repliesi was asked to do a program which can find if a 2d point is inside a triangle or not, only the 3 points of the triangle were given. i planned to do this using the slopes of the 3 sides, then with y-y1=m(x-x1) using the other vertex and the point being checked see if the slope was the same sign and on the same side of the line. if this was true for all 3 then the point is inside the triangle the problem is i cant think of a logical expression for the if/then/else structure to show this anyone know what i should use or should i just go down a completely different route?

Here is the code:
Public Structure Triangle
Shared a As Double = 1
Shared b As Double = 1
Shared c As Double = Triangle.FindC
Public angleABC As Double
[Code] .....
I am receiving an error in the function. "Triangle.angleABC" is generating :"Reference to a non-shared member requires an object reference". I need to find the hypotenuse for this Triangle. I have tried setting the variable as an object, this does nothing for the error. Also I've tried to use Public in the function and I receive an error stating it needs to be shared. I would like to work the the Structure with out running any functions on it first.
