Creating A 3d Gl Graphics Chat - & C# ?
Sep 19, 2011
I want to create a 3d graphics chat. (Think Imvu Not Single Life. I tried opensim, that's a virtual world, not what I'm looking for, plus would prefer to code my own, as I was needing to rewrite so much)This chat I would run between friends on my own server (no monies for server costs)
First I need to know if I am on the right track or not.
ie : need 3d graphics engine at base ? (Any opensource ones I could look at legally to learn from?) need instant group chat engine?(Any opensource ones I could look at legally to learn from?) need login forms, web browser/viewer to run graphical chat in? plus of course I would need a database of meshes and so on?
So first I need to know if I'm looking into the right areas, plus where to find up to date tutorials (ie links) the web is huge? (Oh and opinions from more experienced people.)
Furthermore can this all be coded in vb.net or do i need to code part in C# and add together, can that be done?
Plus I am using a trial version of ms visual studio 10, I am unable to purchase it when trial runs out and do not know what I can switch to then that is free an legal to use, to learn an create opensource projects.

I have google it but I couldn't find the answers. So basically I want to make a Client-Server chat. I just want to creating each server for the clients to entered the chat room with each different server, e.g: client 1 and client 2 entered chat server 1 (just a name of a room), client 3 and client 4 entered chat server 2 and so on. How I can do that?

I am using VB.NET to try and capture a portion of the screen so I found this code in several places to capture the whole screen:
Dim screenSize = SystemInformation.PrimaryMonitorSize
Dim bitmap = New Bitmap(screenSize.Width, screenSize.Height)
Using g As Graphics = Graphics.FromImage(bitmap)
g.CopyFromScreen(New Point(0, 0), New Point(0, 0), screenSize)
End Using
bitmap.Save("c:scratchscreenshot.png", System.Drawing.Imaging.ImageFormat.Png)
This works with no error throw and the file is created successfully but the resulting image is completely transparent (it is the correct size) - This question relates to the same error but the solution is to use Win32 GDI which I want to avoid if possible

I am creating a multiplayer chess game in Visual Basic.Net and I need to create tiles for the game. Earlier, I used buttons for the tiles, but then I realized that not only did they look ugly, but the coding part also became a problem. Also, the images of the chess pieces didn't properly fit on the buttons and they became distorted. Also, shifting the image to a different button every time a move was played also became very inefficient. So, in view of these difficulties, I want to build a proper board, but I have no idea where to start from or what controls to use for the design.

I am creating an application with mlutiple forms. When you click on a button in the main menu, the main menu will close and the new window will be diplayed. When you hit back on the new window, the main menu will be displayed.I know how to show new forms by using Form1.Show(). When I try to return to the main menu by hitting a back button I created, the main menu does not show up, but the program continues running. In the first form, I have the code: [code] Also, am I creating the new forms the right way for an application the will have maybe 15 forms?

I've been trying to get some help for this in another thread,but it looks like it's a task that is going to need a wider audience to try and find someone who knows something about writing/creating procedural textures at the pixel level in VB.Net. The VB6 example I'm trying to convert to VB.Net is attached to this post.

I believe that this is in the correct forum due to it being about creating an interface item, but if I am wrong then let me know and I'll try and bring this thread to the attention of the mods to be moved to a more appropriate forum. I am currently trying to create a generic navigation control with a similar style to the outlook navigation bar. I have figured out how I would be able to dynamically create the bottom part where you select the menu option, but I'm struggling to figure out how I would be able to create the top part, which can contain any user control that the developer would want.
So basically what I'm trying to figure out is, is there a way to allow for a developer to add controls to a specific area of your user control?If there is a way of achieving that then if anyone knows how to do this;In ASP.Net you have the login controls and with one of them, you are able to have different views depending on whether the user who is viewing the web page is logged in or not. Is there a way of achieving this in VB.Net for a user control that could be set up so that I could have the developer able to switch the view in the designer to show them the view for when a specific navigation option has been selected.
The one thing that I have thought of that could possibly cause a problem is having the capability of knowing when one of the user controls has been clicked, while I haven't figured this out exactly, I believe I should be able to achieve this by having an event for the navigation user control that provides the developer a reference to the control.
While I would hope that I have explained what I'm thinking well, its before my first coffee of the morning so I might have missed out some detail which would help someone to help me if I have then please let me know and I'll provide any details required.Also if what I'm envisioning is Pie in the sky, then let me know and I'll just have to make a base which I would just have to make a more bespoke system.

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...

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

ok, i know the code is a little rough, but it should be good to give you an idea of what im trying to do, if not i will still explain.simply draw 2 lines one from left to right, another from top to bottom, intersecting through the tip of the mouse.ok, theres no problem there the lines draw perfectally the way i want them.... BUT! now heres the issue im having.i cant get rid the previous lines.i did a bit of good old "Google'ing" and ran across a few links that all pointed me to the ReDrawWindow API, so i tried (as you can see in the above code) but i just cant seem to get it worked out.

So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.

My application is all centered around one form with lots of graphics drawings on it.All these drawings take place from within a paint event handler. However, the amount of code within that sub is becomming unwieldy.I have been trying to move sonme of it to another class and use the "dim temp as Graphics = e.graphics" construction to continue to draw graphics. However, I get all kind of argument exception runtime arreors when doing so (and I do not get these with the same graphics operations directly from the original paint event handler. I have also tried to pass on the original e argument, but with the same result.Is my conclusion that there is no solution to this so to continue with the unwieldy amount of code,correct, or am I mistaken somewhere. the "dim temp as graphics = e graphics" is recommended.

I load my picturebox with a jpeg. If I put my DrawObjects() sub into picturebox paint event.When ever a picturebox.refresh or picturebox.visible = true (vb.net seems to draw my DrawObjects() first, then load the jpeg Image over my drawing - erasing drawing) Is there a way to get the picturebox to redraw the jpg image first then draw on it, in picturebox paint event?

In a Previous Thread, I asked some questions about how to create graphics. Everything was OK, until I realized that the graphics are really slow. While I was trying to find out what the problem was, I realized that the processor load was about 50% and my graphics card was not used at all. So doesn't Visual Basic use the Graphics Accelerator to process graphics? What I made is not a real program. It's like an experiment (I tried to make an image flip). Here is the Code:
