Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
I'm reading data from the microphone and want to perform some analysis on it. I'm attempting to generate a spectrum analyser something like this:
What I have at the moment is this:My understanding is that I need to perform a Fourier analysis - a Fast Fourier Transform ? - to extract the component frequencies and their amplitudes.
Can someone confirm my understanding is correct and exactly what type of Fourier transform I need to apply?
At the moment, I'm getting frames containing 4k samples from the mic (using NAudio). The buffer I've got is 16bits/sample (Signed Short). For reference, the above plot shows approx half a frame I'm coding in VB so any .Net libraries/examples (preferably on NuGet) would be of most use. I believe implementations vary considerably so the less I have to massage my data, the better.
I am drawing an arc within a square or a polygon with the maximum possible radius inside.When the arc is drawn within the boundary of the square or polygon,the arc length will intersect at few points on the square or polygon.How to find the coordinates of the intersecting points of arc at the periphery of the square/ polygon?
I have a large set of latitude and longitude coordinates from a GPS which, when plotted, creates a 'jerky' line over time. I would like to 'smooth' this line into another set of coordinates which I can then plot to make the track more 'smooth'.
I may need to add more intermediate coordinates to do this. I just wondered if there are any code snippets out there or even MS Excel functions
documents that are required for a project. Such as:e.g: What sort of document I have create at the requirement analysis phase...etc I need to know all the documents that are required from start to end of the software project.
What's the part that MSF (Microsoft Solutions framework) plays?If we need to use MSF, what sort of documents that are required from it?
I'm using VB 2005, and am hoping to have streaming video to my application with some sort of video analysis. Right now as a test, I have an axWindowsMediaPlayer control playing a video from a URL. I'm figuring I need to be able to detect the colors of the pixels in the video for simple analysis, but I haven't been able to do this yet. I've been able to view the pixel colors in every area of the screen except for the media player window (just shows up black, as if you were to make a screenshot of the media player video). Is this at all possible to do?
I decided to try the Code Analysis tool that came with VB2010 (at some levels). It produced LOTS of fascinating comments. Many of the comments make no sense, such as one about not disposing of a type on all paths when there is only one path that ends with an explicit call to object.Dispose. I think the analysis engine is looking at some of the calls, but they all return to the caller properly.
I'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.
I am looking for a way to be able to export a beizer-curve (a curve like in the example below)from my app to a DXF-file.What I need is a way to calculate the control-points and parameters that DXF-format requires (format as in link below)
How hard would it be to graph a curve of a function in a VB form.
Attached is a graph from excel which is exactly what I need to do.
I have the function of some fluid properties and I'd like to choose a min and max temp then have the function graphed, with temp as the x and the fluid property as the y which would auto scale to fit the curve.
Actually now the program i have to return the properties at one temp is just a GUI front end to call a fortran program to return the properties so actually if I just use that it'd be graphing points and not directly from the function. I can always make it completely VB based if graphing from a function is easier than points. It'd be a slight pain to rewrite all the code for the functions though.
I am trying to write code in vb.net to find a equation when data points are given. For example (1,5),(2,6) etc. I need to find a equation(not necessarily always linear) from the given points. How do I calculate a trendline for a graph? How to get equation.
How to make a color curve adjasment for editing colors of an image?I found a C# project on Mr.SkyDrive but the problem is the coloring adjasment, because the coloring adjasment wasn't as other programs adjasment it wasn't correct if you view the image closely you will see some red, pink, and green pixels: (the curve like this must make the image negative)
I have several points where I draw a curved line from point to point using:e.Graphics.DrawCurve(p, theArrayOfPoints)Was wondering is it poss to draw text starting from the 1st point that followed the curve? This way the text bends.
The picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.
I intend to choose developing a Web Content Management System using asp.net with VB.net 2008 but I'm not sure about how long it takes to program such system. Is 4 months enough for developing such system? This 4 months is the duration of this semester and Includes about two months for analysis and design and the rest is left for implementation.
I have been tasked with getting a asp.net (vb.net) talking to an analysis services engine on our production servers. The web server is a separate machine from the web server.The web server runs as the IUSR_ user.The application (of course) works on the development machine which has both IIS and Analysis services on it.The problem I see appears to be a permissions error (returned in the browser by the asp.net app):An existing connection was forcibly closed by the remote host ....
it is described in a similar post here: http:[url]......I am not a system admin, nor am I an expert in analysis services (why have I been tasked with this you ask? because other people haven't been able to get it working and it has fallen on me). I have tried creating and adding the user (IUSR_) to the sql server and added that user to the role. While that worked on my local machine, it did not work in our production environment where the sql and web servers are separate.
With this assignment, you are provided with an incomplete object-oriented implementation of the GAME MANIA software system based on Visual Basic 2008. The specification and the subsequent modelling are explained in a case study titled Game Mania: GAME AND GAME CONSOLE RENTAL STORE.
An implementation of the following classes are made available as the basis of your development work:
Note that the user interface provided is very basic. You need to change it, as you feel appropriate so that it will reflect the required functionality. For example, in the present implementation version, no provisions were made in the user interface for querying and handling fines associated with late returns.Providing this aspect in the user interface might be necessary as part of handling renting of games and game consoles.
I have a website where people do the data entry. I have data stored in SQL server.Now I need to push the data to 3rd party to do some analysis work.What are my options to do this kind of job?
I'm writing a threaded multi-client chat application in VB.NET(2008). While the thread is running and a message is received from the server(in this particular case: "ping") i wish to copy the content of the variable holding the newly received data to another variable(as that first variable is constantly changing) and then later call the Checkmsg() sub which contains a select case to analyse the string and notice a particular command(in this case, when it notices "ping" as received data, I want it to send "pong" back to the server.) and react to it. Now the problem is the code actually "jumps" to the Checkmsg() sub, and fails to compare properly the received data to my select case argument. I've tried setting messageboxes at a couple of place to see if my data was somehow changed but even before the line that compares the two strings the message box prints "ping" and the select case is set to react to "ping" but it wont "move". Now I don't really understand, i've done much vb programming but i'm learning threads.
