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]
View 1 RepliesCurrently 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

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.

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

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.

What I'm doing is trying to generate a number 1 through 4 which was easy enough but next what i want to do is assign four variables with the four generated numbers which i do. My next problem is making sure each different variable gets a different number which is a nightmare for me. I tried doing a For loop to see if it would keep generating until it was a completely different number though it would be a 25% chance to get that possibility (actually less because the other three numbers can be the same at this point) i give it 1,000,000 and still 1/4 of the time the first number is the same as one of the other three.
Today I was playing around with Entity Framework and I've read that the generated IL for C# was different than VB.NET for the following code:

As it seems the VB.NET version of this code will contact the database every time the code is executed while the C# version will retrieve the entities from the cache when the code is executed multiple times.Why would they make both languages behave in such a different manner?It was my misconception that both languages just differed in syntax and had almost exactly the same generated IL.Are there any more examples where both languages generated such different IL?

I have 2 arrays that are generated through a function as follows:

So basically theres a list box of co-ordinator IDs and a list box of the positions they are in. On another form there is a combo box with the list of ID's that is transferred from the list box on the processing form. I want to display the Position of the Co-ordinator when their ID is selected. How do I match the positions up so when an ID is selected in the combo box their position will appear?

View 2 Repliesdynamically creating buttons with images in them and then accessing the on click event for that button. However lets say for example I have three buttons created during run time, button 1, 2 and 3 for simplicities sake. Each button needs to correspond to a value (lets say one, two and three). The problem comes in when i want to, for example, click on dynamically generated button 3 and have it display "three" in a message box. But button 2 might close the program. How can i reference an event when i don't know which button corresponds to which action..
