VS 2010 - Mesh Viewer - Show A Generic Mesh And Texture ?
Jan 26, 2012
I am creating a script editor in vb for a game engine and all is fine with the editor, I just cannot for the life of me get a mesh viewer working. If you are familiar with Unity3d Editor, it has a small 3d viewport that simple shows the mesh associated with the asset script being created where you can click drag rotate the mesh to have a look at it with the selected textures applied.
I have spent many hours digging through msdn trying to figure out how to do this. All samples I find are done in c# none in vb. I have even used code converters with no luck. Bot sure what sdk(s) to use either. How to do it as in setting up a project that has a basid 3D viewport that will also applie selected textures to the mesh? Even if it is hard coded to show a generic mesh and texture, It should be enough for me to grasp how to set it up.

Im currently working my way through understanding direct3D with visual basic for windows mobile. So far I have managed to write a fairly decent engine that allows me to create and transform any number of 3D primitives and 2D sprites. However I cant seem to figure out how to get Direct3D to apply any sort of shading to my meshes. Regardless of what angle they are to the camera, or their position in 3D space, they remain a solid flat color on every single polygon of the mesh.

I looked at several questions/answers posted already such as this one on a planar polygon but could not find one that explains results in 3D such as the one shown in this paper and this one on "point cloud skeletonization through Laplacian-Based Contraction" where this quadratic equation comes back in both.

with a college assignment. We are to make a program for a school class. It is on Flags of Europe. A Picture Viewer should show a flag and the students must type what the flag is in a text box. If it is correct it must say so in a label and display the next flag. I want it to add the correct answers the student got out of 10 flags.

I have a client, who is running Windows 2008 Server 64 bit. He is running our software, it has a built in crystal report viewer functionality. The print dialogue just wouldn't work no matter what. It worked on our 32 bit box and we verified it. I verified it on our 64 bit box, and the print dialogue didn't open either. I did some research online. And one suggestion is to set m_printDlg.UseEXDialog = True. I tried that, but that did not work either...
Here is the code snippet.
#Region " Methods "
Public Overrides Sub PrintReport()
' NOTE: Do not use bug in reportviewer
'MyBase.PrintReport()
Dim objRpt As ReportDocument = CType(Me.ReportSource, ReportDocument)

After several hours of searching the internet I could not find any Report Viewer tutorials that show a project that contains a parent/child report. I'm using rdlc report files.I can create a single report but we want to create a report that shows shows invoice header information followed by the invoice details followed by the next invoice header and details and so on.
If a sample project is not available, do you know of an online tutorial that shows how to do it?I saw something that might help on gotreportviewer.com about subreports, but it's in C# and not VB.Net so I could not figure out how it works.

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.

i'm developing a simple 3D Cad Application that renders some created objects. I'm able to apply a color-based material to the objects but not to cover their surface with a texture, such as a bitmap. These are the two main code blocks of my application:
This code, creates the objects and creates materials for them. (To draw the objects, i'm using the Mesh class' methods):
objects(0) = Mesh.Box(device, obj.SizeX, obj.SizeY, obj.SizeZ)
materials(0) = New Material
materials(0).Diffuse = obj.Material
materials(0).Specular = Color.LightGray
materials(0).SpecularSharpness = 15.0F

I created a module for the functions to create a bmp by combining 4 bitmaps together and using a bump map. This part works. It's as soon as I try to save the bitmap to a memory stream I get an error.[code]

In the project I'm working on I've been using some gif images to define one or more texture brushes. I have the images in a folder and I know how to define the texture brushes as follows.
[Code]...
Let's say I add the images as image files to my application using "Add Existing Item". Is there a way I can define the texture brushes with the images that have been added to the solution in that way and if so could you show me the exact code.

We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.

I have developing an application for our NOC to use at my company, and I would like to implement a VNC viewer. I have never coded this in .NET before. how to get started? All the examples I find, such as TightVNC or VNCSharp, are coded in C# and that is not a language I am familiar with. I am using Visual Studio Pro 2010 and programming in the Visual Basic.NET language.

In my earlier post I failed to mention that my vb 2010 is the express edition. I know that report viewer is not included in the free edition. I downloaded the report viewer for vb 2010 redistributable and it installed fine. Where did it install to is another question, I can't find it anywhere. when I right click on the toolbar and select choose item, the report viewer doesn't show in the net frameworks components list.

I have been provided with a series of RDL files and dataset specifications for each RDL report.I have successfully generated the proper data tables for each report specification but have not yet figured out how to successfully use the reportviewer in my application with the provided RDL files.Due to the large number of reports I will be working with I need to hard code the reportviewer instead of using the control in design mode.

I am currently working with a program where the user is prompted to click certain points on a picture within the picturebox on my form. The issue is that some of the points need to be pretty precise and i want to give them controls to slide the points once they have clicked them. The method for sliding is fairly simple but i want to be able to graphically show it in a secondary picturebox.

I want to add a reference to Visio Viewer 2010 to my toolbox so I can add it to a Windows Form I am developing (not a web form). I went thru both the .NET and COM references to select the option, but it does not seem to be listed anywhere.

Consider:
Public MustInherit Class Column
Public ReadOnly Property ReturnSomethingUseful() As Object
Get
'return something useful
[code]....
But this gives the following error:
Public Overrides Function ParseValue(sValue As String) As Boolean'
cannot override 'Public Overridable Function ParseValue(sValue As String) As Object'
because they differ by their return types.
I accept that you can't do this, but I'd like to be able to preserve the semantics of what I'm. trying to do, which is to have an untyped version that deals with Object, but a typed version in derived classes that knows about the specific type T.

I am trying to construct a generic interface class with generic functions. My goal was to use this to implement multiple worker classes for database interaction that have the same basic functionality. Each class will deal with different object for example, category, product or supplier but unless the the functions in the interface are generic that this won't work.This is the interface code that I have but I don't know if I have done it correctly.

Ok say I have this Dim MyQueueOfClients as new Queue (Of TcpClient) I also have two threads.
In thread one a TcpListener waits for connections then adds a connected TcpClient to MyQueueOfClients.
MyQueueOfClients.Enqueue (TcpClient)In thread two I then check to see if there are any Clients in MyQueueOfClients. If so I then remove them from the MyQueueOfClients.
MyTcpClient = MyQueueOfClients.Dequeue I think the question Im asking is this thread safe?
Can I Enqueue and Dequeue at the same time from different threads?
Well it helps if you read everything. I have just read this as well
A Queue(Of T) can support multiple readers concurrently, as long as the collection is not modified. Even so, enumerating through a collection is intrinsically not a thread-safe procedure. To guarantee thread safety during enumeration, you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.

I am trying to create a list of a generic type in vb.net 2.0 framework.
This is the generic type definition:
Public Class GenericParamMap(Of T)
Public Sub New(ByVal pParamName As String, ByVal pPropValue As T)
mParamName = pParamName
[Code]....
The compiler does not allow a "T" in the method's parameter because it's not defined, but I'm not sure how or where to define it. I thought it was okay to have a generic method definition.

(Not really sure if I phrased the question correctly...) I want to create a lambda expression that would take an Object, attempt to convert it to a passed-in Type, and print to the console whether it was successful or not. At a glance, the lambda expression may seem a pretty silly way to accomplish this task, but I'd really like to know what I'm doing wrong, so I can better grow my skill set.
VS gives me a designer error about the second "T" in the expression below, telling me it isn't defined) This is where I left off:
