[RESOLVED] Simple 3D Graphics With DirectX

Jun 6, 2010

I'm just having some difficulty with nitpicky details. To give you a gauge of the level of programming I'm at I'll just tell you about some of the work I've done. Of course, you can skip down to the last paragraph if you don't have the time.I've created an emulator for a programming language I call "Blue Code". It's kinda a spoof on Redcode, which you may have read about before. You load programs which use simple commands like add, divide, copy, jump, split (like making a new thread), etc. You can load multiple programs in and each instruction sits on a line of a circular memory. Then each program takes turns trying to get the other to run an illegal function, at which time it looses. I think it's quite a bit better than Redcode actually.I also wrote a program a couple years back (when I was 13?) that draws fractal trees, it's quite fun.

So, I have a pretty good grasp on VB, but recently I got into 3D graphics using the Direct3D library. Unfortunately, the function I'm using to save meshes is not working. I know the rest of my program works just dandy because I've loaded quite a few sample meshes. Now, I've come to the conclusion that my saving code is irreparably broken, so I won't even show it to you. What I need is somebody to write an outline of what I need in a saving function, or, better yet, actually write a saving function which I can customize to my purposes. The parameters are, a somewhat unconventional List(of List(of CustomVertex.PositionNormalTextured)), List(of Material), and List(of String). List of lists includes a bunch of lists of vertices I wish to use, where each list represents a subroutine. The list of strings and list of materials represent texture file names and surface materials respectively.

Rendering Graphics Efficiently - DirectX - Graphics Card And Use Of DirectDraw Or OpenGL

Sep 23, 2011

We have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.

The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.

So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

DirectX - How To Create 2D Graphics

Aug 20, 2009

I have found an example about how to create 2D Graphics in Visual Basic using DirectX here. I have created a new Windows Application, I have copied the code, but I get errors. The code seems to be OK, but the application refuses to start. I have the nVIDIA 7300LE Graphics Card and I'm using Windows Vista x64 with DirectX 10 and Microsoft .NET Framework 3.5 SP1. I have also downloaded the DirectX Redistributable Package (March 2009) in order to make my application work...

Draw Simple Graphics In Program?

Oct 11, 2009

I'm a unviversity student and for an assignment we have to make a simple project where the user specifies a shape and a color, and then the shape is drawn in some kind of space. So like they choose circle, green, and in this blank space on the form a green circle appears, pretty simple. Anyways we have some kind of msdn alliance thing where we can download Visual Studio for academic purposes, so I downloaded Visual Studio 2008. I spent about an hour going through the tool box trying to figure out what could possibly allow me to draw stuff in it, and I'm really not sure what it could be. On some online tutorials it said something about a function on picture boxes like picturebox.Circle(100,100), 100, vbgreen or something similar, and when I tried making a picturebox and writing this code nothing worked. My friend told me to use a 'canvas' but neither of use know how to actually find such a control (its not in the toolbox).[urls]....

Interface And Graphics :: Build An Application With A Simple MENU?

Mar 31, 2009

current version is 2008 I'm trying to build an application with a simple MENU. When the user clicks on a Menu Item i want the container to show some controls, now when the user clicks another Menu Item, the container needs to change and show other controls, and so on with every menu Item the user clicks, one at a time.

I thought of panels showing and hiding for every menu Item clicking, but that would use a lot of memory as ALL the controls would be created, some of them just not showing. I also though of an MDI application, but i dont want multiple forms (with the menu bar) opening inside one form. I just want the actual container of one form to change.

[RESOLVED] Application For 64 Bit Computer?

Apr 2, 2009

I wrote a small application for a friend that opens a Excel sheet, get's some data from it and stores that data into a file. I compiled it for AnyCPU (I also did a compile just for his 64 bit machine, same result).Here is the problem:He is able to run the program on a 32 bit computer without any problem, it just won't work on his 64 bit computer.Here is the error he is getting App failed to initialize properly (0xc0000135)

Is this my problem or could this be his problem? As far as I can tell I'm all up to date with VS2008.Is there somewhere I can look specifically what the latest build is for VS2008? I am using VB2008.

Resolved Stumped Regex Works In C# But Not VB?

Jan 12, 2010

I'm working through the Pro ASP.NET MVC Framework book by Apress (which is great, btw) and it's in C# although we mostly work in VB so I'm "translating" the examples along the way. So far so good but I ran into something that has thrown me.Long story short we need to validate that the string the user gave us as an email address. This returns true in C#:

Console.WriteLine(System.Text.RegularExpressions.R egex.IsMatch("Me@me.com", ".+\@.+\..+"));

But this returns false in VB:Console.WriteLine(System.Text.RegularExpressions.R egex.IsMatch("Me@me.com", ".+\@.+\..+"))

VS 2008 [RESOLVED] System.Net.Dns.GetHostAddresses

Apr 9, 2010

Yesterday s**ked, and today ain't (sic) looking better. I have an application I have been working on and it can be slow to start when my ISP is down because of DNS. My ISP was down for 3 hours yesterday, so I didn't think much about this piece of code I had added, until I found that it is always slow to start. This code is supposed to return your IP address and my reading of the link suggests that should be immediate, but it isn't, at least on my machine.Oh, and yesterday before the internet went down, I upgraded (oymoron) to XP SP3, and have had other problems.So my questions / request:

1. Am I doing this right?

2. If you run this on your machine does it take 39 seconds to return your IP address? [code]

Resolved Normalize Path With Length More Than 260 Chars?

Feb 8, 2010

My issue is to combine two paths which one or both of them may contain double dots. I used Path.Combine(string, string) and the returned string is still a long path as a result of concatenating these two paths. Single or double dots are not eliminated.

So, I tried to use Path.GetFullPath(string) method with the concatenated path as the argument.PathTooLongException is thrown because this path has more than 260 characters. However, if this path is normalized, it won't exceed the maximum characters for a file path.

VS 2008 [RESOLVED] Threads And Problem With Form

May 26, 2009

Hi

I have a thread that it calling many processes.

While the processes are executed (spends some seconds or minutes in completing all the tasks) I show form "Please wait to complete all tasks".

But one of these processes I have to show a form because the user has to choose a few data. But the problem is that this form is showed minimized.

Already I have tried to show it maximized and to bring it to the front but it does not do it.

how I can show this form to front and maximized?

My actual code is:




f= New frmLPlantillas
f.WindowState = FormWindowState.Maximized
f.BringToFront()
If f.ShowDialog() = DialogResult.OK Then
value1= f.xxxx
value2= f.zzzzz
value3= f.aaaa
value4= f.bbbbbb
Else
Return False
Exit Function
End If

Thanks in advance.
