View 4 RepliesProgramming Languages - .net Delegates Strongly Typed?
Dec 14, 2011I'm learning delegates in VB.NET and am confused about delegate types. In reading about delegates, I learned that delegates are a data type that can refer to a method with a particular kind of signature. So in the same way that a String can refer to characters, a delegate can refer to a method (for instance) that takes an integer as input and returns an integer as output. But in playing around with delegates, I found that this was not the case. The code below compiles and runs--even though I don't obey the 'typing' in my delegate signature. I'm confused. Am I missing something?
Public Delegate Function myDelegate(ByVal i As Integer) As Integer' int in, rtrn int Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim md As myDelegate 'should be of type int in, rtrn int md = New myDelegate(AddressOf squared) 'allows assign to string in, string out

Do All Programming Languages Use Static / HEAP & Stack Areas To Store Memory
Apr 9, 2012Do all programming languages use the Static, HEAP, & Stack areas to store memory? Does understanding this help me with debugging in any way? How do I query or access the memory in .NET would I ever need to do that? Or the memory addresses?What keywords would I type into Google to get more on how the .NET CLR uses memory?I'm learning Java and am trying to compare .NET and Java and how memory management differs and is similiar.

View 3 RepliesExcel - Code In VBA And Recording A Macro - Input A Values For The X Axis Rotation And The Y Axis Rotation
Sep 16, 2009I am having some major problems with the code in VBA and recording a macro didn't get me anywhere nor is the VBA help file. I have to have it so that I can input a values for the x axis rotation and the y axis rotation so that my 3d surface graph will rotate whatever values I input, the 3d surface graph will rotate those degrees. I also have to have a method for having the default rotation. I was also wondering how to put scroll bars for the x and y rotation. The only other thing I am having trouble with is having an input to check box for right angle axes. So far I have two cells for entering the x rotation value and the y rotation value. I also already have my 3d surface graph.

Case-sensitive Languages Vs Insensitive Languages?
Nov 27, 2010visual basic.net is case insensitive so it allows the coder to write without caring or remembering the casing of variables. it also relieves from the 'undeclared variable' errors if you use the variable in another case than the one used in declaration. The fact that its line termination is a line feed makes it even more readable unlike C# or c++ that need good care in the casing and contineous war with following up with the {}, matching them and figuring out which is for which.my question is what are the advantages of c# over vb knowing that both get compiled to MSIL so there is almost no performance difference between the two languages?

VB2010 Can't Find Images After Publish And Put On Another Computer
Apr 30, 2010I created a hangman game and It works well when I debug, but when I publish and place it on my son computer, when you guess a letter wrong it shows an error and says it can't find the images. I just it is something that I'm doing wrong but I don't know what. Some of the thing that I have tried is including the images in resources. I believe that it has something to do with the startup path, the path that the images are looking for does not exist. The installer installs the program in the programs file

Axis Of Rotation In Vb?
Jan 29, 2011I have created some 3d models(VB) for display in a WPF 3d Viewport and would like to rotate them. I would like to rotate them about an axis of rotation defined by a line through two 3d points. All the examples seem to rotate about one of X Y or Z axes and are not helpful for a more general approach. The angle of rotation is easily found. My maths is a bit rusty now so is there a function that would calculate the axis easily ?

3D Object Rotation In 2008?
May 19, 2009I'm developing a sun shading analysis tool, and part of the analysis involves rotating a house (modelled as a cube consisting of 8 points) by the solar azimuth and solar altitude angles. The reason for this is to determine if the wall in question is facing the sun, and if so I run a shading analysis using a scanline algorithm to determine the percentage of wall plane that is in shade from a tree in the yard (this is modeled using overlapping 2D polygons). The purpose of the rotation and tilt of the object is so that the wall plane is directly perpendicular to the sun, so that the analysis can be done in 2D as opposed to 3D.
I first rotate each point of the house (which is stored in an array) through the azimuth, and then tilt it up through the solar altitude angle. I have set up my 3D coordinate system using the standard right-hand rule for orientation of the x,y,z axes. I'm using a basic rotation matrix as follows:For the azimuth, I am rotating around the z-axis, so I am using the following matrix transformation.
[x',y'] = [x*cos(azimuth) - y*sin(azimuth) , x*sin(azimuth) + y cos(azimuth)]For the altitude, I am rotating the object about the x-axis to tilt it up. I use the initial z-coordinate and the transformed y'-coordinate for the altitude tilt calculation.Each point, when completely rotated and tilted, will have a distinct set of coordinates: [x', y'', z'].Individually, the rotation and tilt work fine. But when I try to do them consecutively, I run into problems.

View 2 RepliesC++ - Direction Of Shortest Rotation Between Two Vectors
Jun 13, 2012my question is regarding working out the direction of the smallest angle between two vectors in 2D. I am making a game in C++ where one of the obstacles is a heat seeking missile launcher. I have it working by calculating the vector between the target and bullet, normalising the vector and then multiplying it by its speed. However, I am now coming back to this class to make it better. Instead of instantly locking onto the player I want it to only do so only when the bullets vector is within a certain angle (the angle between the bullets vector and the vector bulletloc->target). Otherwise I want it to slowly pan towards the target by a degrees thus giving the player enough space to avoid it. I have done all this (in a vb.net project so i could simplify the problem, work it out then re write in in C++). However the bullet always rotates clockwise towards the target even if the quickest route would be counter clockwise. So the problem is working out the direction to apply the rotation in so the smallest angle is covered. Here is my code so you can try and see what I am describing:
Function Rotate(ByVal a As Double, ByVal tp As Point, ByVal cp As Point, ByVal cv As Point)
'params a = angle, tp = target point, cp = current point, cv = current vector of bullet'
[Code]...
I had was to work out the bearing of the two vectors and if the difference is greater than 180 degrees, rotate clockwise otherwise rotate counter clockwise
DirectX.Direct3D Rotation And Textures?
Mar 12, 2011SI like doing random things like 3D objects inside a windows form. With that said, I'm creating an application that will, eventually, write the code for me, after I do it myself visually.If you run the app it will make some more sense I guess.Now, to rotate the cubes, I'm using
.Transform.World = Matrix.RotationYawPitchRoll(CSng(CubeRx(1) / 10), CSng(-CubeRy(1) / 10), CSng(CubeRz(1) / 10))
now I do not want the world to rotate, just my individual cubes.Here's an example of me referring to my cube in action
If howmanycubes >= 1 Then
' vb2 = New VertexBuffer(GetType(CustomVertex.PositionNormalColored), 36, d, Usage.Dynamic And Usage.WriteOnly, CustomVertex.PositionColored.Format, Pool.Default)
[code]....
how to apply textures to the cube.instructions:When running the program, type in values on right side and click create cube.before you click create cube again, those same text boxes will adjust your current cube.Then when you click create new, it places another cube ontop of your current cube, so you'll need to give it new values.Not much validation is going on so some bad values will cause crashes.
Get Text Field Rotation With ITextSharp?
Jun 4, 2009What I need to do is query an iTextSharp AcroField to check if it is rotated, and if so capture the value of the rotation.So If I have the following field:

afi = af.GetFieldItem("fieldName")
What do I need to do to get the rotation (in degrees) of that specific field?
Custom User Control Graphics Rotation?
May 31, 2010I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008.so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate.so far i've tried this:
Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle)
gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74)
gL.RotateTransform(angleLongNeedle)[code].....
As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control.
