View 37 RepliesI need to overlay a small bar along the top of the screen over a fullscreen DirectX game. I have searched for a while but I have not found any code examples for VB.NET 2008 (I've never used any previous version). How can I do this? Would this involve learning DirectX programming?
View 2 RepliesI'm using using System.Graphics for my latest project (A simple 2D application). Problem is, it gets a horrible FPS and I'm only drawing 8x8 tiles (usually 10-12 is enough to bring it down to 12FPS).
A friend of mine suggested that I use DirectX. He also suggested XNA but I opposed because I don't want my clients to have to install the XNA distributional. DirectX is common enough (to my knowledge) and I can just include the dll's if I need to.
So, my search began. I've been looking only for DirectX 2D tutorials for VB.net. I've had no solid success thus far. In truth, all I need to do is be able to draw bitmap x at position pos.
I've been using System.Graphics and a hacked up bitmap as my buffer thus far so I'll go for any improvement that I can get.
I'm using VB.net so I'll be ok if you give my one for C#, I'm pretty good at being able to read it (and I have a nice converter too). I would just prefer VB.net to save time.
I have been working on an angle calculating program. I have incorprated a feature so you can type the angle and the program draw it. I have since added a few new features and updated everything as such. For the life of me I can't figure out why the draw angle has stoped working. let me just paste some code.
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
[Code]....
Right, the program isn't so complicated. The important bit is that you type an angle in textbox1 and hit enter. Then what happens is the angle is calculated against a base line (one of the new features is that this base line can be moved from left to right and center.) the problem occurs when you hit enter, the program doesnt actually draw the line for you.
This is more of a mathematical problem than programming problem.I have created a very basic 3D engine using Visual Basic .Net. It displays lines on the screen with an additional z axis. The engine works, however when part of the line goes below 0 it messes up and starts drawing the line inverted again.
This is how it calculates the points:
y = (point.y / z) + offset.y + camera.y
x = (point.x / z) + offset.x + camera.x
Can anyone work out a way to only draw part of the line when it intersects the z=0 axis?

I want to be able to have a line drawn from point a to b, but be able to rate it 90 degress based on user input so if the user inputs 70 I want it to rotate 30 degree's to simulate a 70 deg relationship to a horizontal line that it touches if that makes any sense. a is starting point b is the user inputs 70 and it draws it at 70 in relationship to the horizontal lineheres the image that i forgot to post above Attached image(s)
I was wondering if anyone could steer me to any good references to using OpenGL in vb.Net? I wanted to try a simple line drawing test to start off with, and came across many old discussions about using CsGl or the Tao Framework. But I could not get CsGL to import into Net2008 (the Add Reference window simply could not see the DLL that was clearly there when using Windows Explorer). And although I could get Tao to import OK, and found portions of one person's project, I figured that somehow the GL window he was referring to had to first be set up as a GL object (new class?).In addition, all the OpenGL books I have looked at only discuss OGL with respect to some version of C.From what I have gathered, you need a connector between vb.Net and the opengl32.dll libraries and that is what CsGL and Tao are about. But the edumucation resources seem very few.
View 13 Replieshow to draw in vb.net, and I figured the easiest way is to get my hands dirty and start coding. I figure that the best way to start is by drawing a line on the form. What I'm trying to do is use the graphics.drawline(), but I'm failing. This is what I'm using so far

I have a question about drawing lines. Most of the code snippets I've seen approach drawing a line with the mouse down as the startpoint and the mouse up as the endpoint. But I am trying to draw a line by startpoint as
a mouse click and then an endpoint as a mouse click just as you do on a typical cad program.
That's vertical and 1 pixel wide. This is for a mulitiprocessor performance monitor.How do I do it....if you tell me which routine to use... I'll take it from there. I don't think the routine is
System.Drawing.Graphics.DrawLine, because it's looks to an external reference like I'm putting random pixels in.If possible I need to put the pixels in by hand. Besides this line of pixeld is another line of pixels for another epoch. They are not related numrically.
My program is giving the error: "End of statement expected" The red lines are the ones giving errors. I'm trying to draw lines on a picturebox to create a graph

View 1 RepliesI'm using vb10.
Is it possible when drawing a line to use a binary pattern? Is there a command for this?
Example:
167 is 1010 0111
Draw a line X32 x Y1 would be: 10100111101001111010011110100111
205 is 1100 1101
Draw a line X32 x Y1 would be : 11001101110011011100110111001101
1's being pixels drawn and 0's not.

I'm trying to make a very simple Silverlight application.I want it to be full-screen, and I want to draw a line onto a Canvas.My problem is that the .Width and .Height of the canvas never seem to have a valid value. The website shows the canvas at 400x300 pixels or so, and when you click on it, it goes into Fullscreen mode.I want to use the Height and Width to find the usable space of the screen. I've tried adding events (thinking that the canvas wasn't yet ready to be used immediate after the full-screen line of code) but the LayoutChanged and Resized events don't seem to yield anything.
View 1 RepliesWhen I try to play an audio file through DirectX, that isn't my development machine, I receive this error.
The DirectX library I'm using is Microsoft.DirectX.AudioVideoPlayback.dll.
I include the library when I build the application and I thought that would work. Both PCs have the same version of DirectX installed. So what else do I need to install?
The app itself is meant to run on a USB, so I can't install it, but I'm able to install 3rd party libraries during the initial load.
I would like to build a line chart which can redraw or change during a period of time with dynamic data. So that the x, y axis will change if out of range. The graph may be somehow similar to Matlab. I am using vs2005.
View 2 RepliesI'm playing an audio file like so:
VB.NET Dim audio As New Audio(Application.StartupPath & "est.wav", True) audio.Balance = 10000 audio.Play()
Which works great. But if I need to change that file, I get an UnauthorizedException because the I haven't disposed of it. But, if I add a dispose after .Play, it won't play.
Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.
