    - by Michael Quiles
    How can I call the button1_Click event in the form closing event so I don't have to copy and paste the code from button1_Click? public void button1_Click(object sender, EventArgs e) { //Yes or no message box to exit the application DialogResult Response; Response = MessageBox.Show("Are you sure you want to Exit?", "Exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2); if (Response == DialogResult.Yes) // Exits the application Application.Exit(); } public void xGameThemeComboBox_SelectedIndexChanged(object sender, EventArgs e) { string folder = Application.StartupPath; string theme = (string)xGameThemeComboBox.Items[xGameThemeComboBox.SelectedIndex]; string path = System.IO.Path.Combine(folder, theme + ".jpg"); Image newImage = new Bitmap(path); if (this.BackgroundImage != null) this.BackgroundImage.Dispose(); { this.BackgroundImage = newImage; } } private void xGameForm_FormClosing(object sender, FormClosingEventArgs e) { // call button1_Click here }

  • setting variables and values in html & js

    - by air
    i have one js file in that js file i have following variables var image_path="images"; var style_path="style"; i want to use these variables in html file(s) like in image statement <img src="path from js/logo.gif"> or in style sheet statement <link rel="stylesheet" href="path from js/constant.css" type="text/css" /> Basic idea behind this is: if we change name of image folder or path of image folder we only do change in one JS file not 1000 html files. same for style sheet. or any other way to do same in java script or Jquery Thanks

  • How to Solve N-Queens Problem in Scheme?

    - by Philip
    Hi, I'm stuck on the extended exercise 28.2 of How to Design Programs. Here is the link to the question: http://www.htdp.org/2003-09-26/Book/curriculum-Z-H-35.html#node_chap_28 I used a vector of true or false values to represent the board instead of using a list.

  • Using selection sort in java to sort floats

    - by user334046
    Hey, I need to sort an array list of class house by a float field in a certain range. This is my code for the selection sort: public ArrayList<House> sortPrice(ArrayList<House> x,float y, float z){ ArrayList<House> xcopy = new ArrayList<House>(); for(int i = 0; i<x.size(); i++){ if(x.get(i).myPriceIsLessThanOrEqualTo(z) && x.get(i).myPriceIsGreaterThanOrEqualTo(y)){ xcopy.add(x.get(i)); } } ArrayList<House> price= new ArrayList<House>(); while(xcopy.size()>0){ House min = xcopy.get(0); for(int i = 1; i < xcopy.size();i++){ House current = xcopy.get(i); if (current.myPriceIsGreaterThanOrEqualTo(min.getPrice())){ min = current; } } price.add(min); xcopy.remove(min); } return price; } Here is what the house class looks like: public class House { private int numBedRs; private int sqft; private float numBathRs; private float price; private static int idNumOfMostRecentHouse = 0; private int id; public House(int bed,int ft, float bath, float price){ sqft = ft; numBathRs = bath; numBedRs = bed; this.price = price; idNumOfMostRecentHouse++; id = idNumOfMostRecentHouse; } public boolean myPriceIsLessThanOrEqualTo(float y){ if(Math.abs(price - y)<0.000001){ return true; } return false; } public boolean myPriceIsGreaterThanOrEqualTo(float b){ if(Math.abs(b-price)>0.0000001){ return true; } return false; } When i call looking for houses in range 260000.50 to 300000 I only get houses that are at the top of the range even though I have a lower value at 270000. Can someone help?

  • How to combine a relative top with an absolute bottom in CSS?

    - by ceving
    I need to define a div which must stay with the top at the normal position, which differs from the top of the surrounding element: position:relative top:0 and which grows in the height up to the size of the surrounding element: position:absolute bottom:0 I have no idea how to combine the both. Whenever I use a relative box I loose the absolute bottom and whenever I use an absolute box I loose the relative top. Can anybody help me how to do this in CSS? Here is an example: <html> <head> </head> <style type="text/css"> @media screen { body { position: absolute; top: 0; left: 0; right: 0; bottom: 0; margin: 0; padding: 0; } #head { background-color: gray; } #rel { background-color: green; position: relative; top: 0; bottom: 0; float: left; } #abs { background-color: red; position: absolute; top: 0; bottom: 0; float: left; } } </style> <body> <div id="head"> <h1>Head</h1> </div> <div id="abs"> <h2>absolute</h2> </div> <div id="rel"> <h2>relative</h2> </div> </body> </html> "relative" does not grow at all and "absolute" grows too much.

  • Flash - Ease out scrolling moviclip, scrolled by sensor on each side

    - by webfac
    I am hoping someone can shed some light on this issue for me... I have a movieclip that is scrolled by means of a 'sensor' on each side of the stage. The clip scrolls fine in both directions, however here is my problem: When the users mouse leaves the stage, the movie clip stops dead in it's tracks, and this does not provide a noce smooth effect. Looking at the code below, is there any way I could tell the animation to ease out when the users mouse leaves the stage rather than simply stop suddenly? Much appreciated! class Sensor extends MovieClip { public function Sensor() { } public function onEnterFrame() { // var active:Boolean; // is mouse within sensor? if ((_level2._xmouse >= this._x) && _level2._xmouse <= (this._x + this._width)) { active = true; } else { active = false; } if(active) { // which area of the sensor is it in? var relative_position:Number; var relative_difference:Number; relative_position = _level2._xmouse / this._width * 100.0; //_level2._logger.message("relative position is " + relative_position); if (!isNaN(relative_position)) { // depending on which area it is in, tend towards a particular adjustment if(relative_position > _level2._background_right_threshold) { relative_difference = Math.abs(relative_position - _level2._background_right_threshold); //relative_difference = 10; } else if(relative_position < _level2._background_left_threshold) { relative_difference = Math.abs(_level2._background_left_threshold - relative_position); relative_difference *= -1; } else { _level2._background_ideal_adjustment = 0; } var direction:Number; if(_level2._pan_direction == "left") { direction = 1; } else { direction = -1; } _level2._background_ideal_adjustment = direction * (relative_difference / 10) * _level2._pan_augmentation; //_level2._logger.message("ideal adjustment is " + _level2._background_ideal_adjustment); if (!isNaN(_level2._background_ideal_adjustment)) { // what is the difference between the ideal adjustment and the current adjustment? // add a portion of the difference to the adjustment: // this has the effect that the adjustment "tends towards" the ideal var difference:Number; difference = _level2._background_ideal_adjustment - _level2._background_adjustment; _level2._background_adjustment += (difference / _level2._background_tension); // calculate what the new background _x position would be var background_x:Number; var projected_x:Number; background_x = _level2["_background"]._x; projected_x = background_x += _level2._background_adjustment; //_level2._logger.message("projected _x is " + projected_x); // if the _x position is valid, change it if(projected_x > 0) projected_x = 0; if(projected_x < -(_level2["_background"]._width - Stage.width)) projected_x = -(_level2["_background"]._width - Stage.width); _level2["_background"]._x = projected_x; // i recommend that you move your other movieclips with code here } } } } }

  • Is there a floating point value of x, for which x-x == 0 is false?

    - by Andrew Walker
    In most cases, I understand that a floating point comparison test should be implemented using over a range of values (abs(x-y) < epsilon), but does self subtraction imply that the result will be zero? // can the assertion be triggered? float x = //?; assert( x-x == 0 ) My guess is that nan/inf might be special cases, but I'm more interested in what happens for simple values.

  • How to edit item in a listbox shown from reading a .csv file?

    - by Shuvo
    I am working in a project where my application can open a .csv file and read data from it. The .csv file contains the latitude, longitude of places. The application reads data from the file shows it in a static map and display icon on the right places. The application can open multiple file at a time and it opens with a new tab every time. But I am having trouble in couple of cases When I am trying to add a new point to the .csv file opened. I am able to write new point on the same file instead adding a new point data to the existing its replacing others and writing the new point only. I cannot use selectedIndexChange event to perform edit option on the listbox and then save the file.

  • Is frozenset adequate for caching of symmetric input data in a python dict?

    - by Debilski
    The title more or less says it all: I have a function which takes symmetric input in two arguments, e.g. something like def f(a1, a2): return heavy_stuff(abs(a1 - a2)) Now, I want to introduce some caching method. Would it be correct / pythonic / reasonably efficient to do something like this: cache = {} def g(a1, a2): return cache.setdefault(frozenset((tuple(a1), tuple(a2))), f(a1, a2)) Or would there be some better way?

  • Why do I get rows of zeros in my 2D fft?

    - by Nicholas Pringle
    I am trying to replicate the results from a paper. "Two-dimensional Fourier Transform (2D-FT) in space and time along sections of constant latitude (east-west) and longitude (north-south) were used to characterize the spectrum of the simulated flux variability south of 40degS." - Lenton et al(2006) The figures published show "the log of the variance of the 2D-FT". I have tried to create an array consisting of the seasonal cycle of similar data as well as the noise. I have defined the noise as the original array minus the signal array. Here is the code that I used to plot the 2D-FT of the signal array averaged in latitude: import numpy as np from numpy import ma from matplotlib import pyplot as plt from Scientific.IO.NetCDF import NetCDFFile ### input directory indir = '/home/nicholas/data/' ### get the flux data which is in ### [time(5day ave for 10 years),latitude,longitude] nc = NetCDFFile(indir + 'CFLX_2000_2009.nc','r') cflux_southern_ocean = nc.variables['Cflx'][:,10:50,:] cflux_southern_ocean = ma.masked_values(cflux_southern_ocean,1e+20) # mask land nc.close() cflux = cflux_southern_ocean*1e08 # change units of data from mmol/m^2/s ### create an array that consists of the seasonal signal fro each pixel year_stack = np.split(cflux, 10, axis=0) year_stack = np.array(year_stack) signal_array = np.tile(np.mean(year_stack, axis=0), (10, 1, 1)) signal_array = ma.masked_where(signal_array > 1e20, signal_array) # need to mask ### average the array over latitude(or longitude) signal_time_lon = ma.mean(signal_array, axis=1) ### do a 2D Fourier Transform of the time/space image ft = np.fft.fft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log(mgft) log_mgft= np.log(mgft) Every second row of the ft consists completely of zeros. Why is this? Would it be acceptable to add a randomly small number to the signal to avoid this. signal_time_lon = signal_time_lon + np.random.randint(0,9,size=(730, 182))*1e-05 EDIT: Adding images and clarify meaning The output of rfft2 still appears to be a complex array. Using fftshift shifts the edges of the image to the centre; I still have a power spectrum regardless. I expect that the reason that I get rows of zeros is that I have re-created the timeseries for each pixel. The ft[0, 0] pixel contains the mean of the signal. So the ft[1, 0] corresponds to a sinusoid with one cycle over the entire signal in the rows of the starting image. Here are is the starting image using following code: plt.pcolormesh(signal_time_lon); plt.colorbar(); plt.axis('tight') Here is result using following code: ft = np.fft.rfft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log1p(mgft) plt.pcolormesh(log_ps); plt.colorbar(); plt.axis('tight') It may not be clear in the image but it is only every second row that contains completely zeros. Every tenth pixel (log_ps[10, 0]) is a high value. The other pixels (log_ps[2, 0], log_ps[4, 0] etc) have very low values.

  • Runge-Kutta Method with adaptive step

    - by infoholic_anonymous
    I am implementing Runge-Kutta method with adaptive step in matlab. I get different results as compared to matlab's own ode45 and my own implementation of Runge-Kutta method with fixed step. What am I doing wrong in my code? Is it possible? function [ result ] = rk4_modh( f, int, init, h, h_min ) % % f - function handle % int - interval - pair (x_min, x_max) % init - initial conditions - pair (y1(0),y2(0)) % h_min - lower limit for h (step length) % h - initial step length % x - independent variable ( for example time ) % y - dependent variable - vertical vector - in our case ( y1, y2 ) function [ k1, k2, k3, k4, ka, y ] = iteration( f, h, x, y ) % core functionality performed within loop k1 = h * f(x,y); k2 = h * f(x+h/2, y+k1/2); k3 = h * f(x+h/2, y+k2/2); k4 = h * f(x+h, y+k3); ka = (k1 + 2*k2 + 2*k3 + k4)/6; y = y + ka; end % constants % relative error eW = 1e-10; % absolute error eB = 1e-10; s = 0.9; b = 5; % initialization i = 1; x = int(1); y = init; while true hy = y; hx = x; %algorithm [ k1, k2, k3, k4, ka, y ] = iteration( f, h, x, y ); % error estimation for j=1:2 [ hk1, hk2, hk3, hk4, hka, hy ] = iteration( f, h/2, hx, hy ); hx = hx + h/2; end err(:,i) = abs(hy - y); % step adjustment e = abs( hy ) * eW + eB; a = min( e ./ err(:,i) )^(0.2); mul = a * s; if mul >= 1 % step length admitted keepH(i) = h; k(:,:,i) = [ k1, k2, k3, k4, ka ]; previous(i,:) = [ x+h, y' ]; %' i = i + 1; if floor( x + h + eB ) == int(2) break; else h = min( [mul*h, b*h, int(2)-x] ); x = x + keepH(i-1); end else % step length requires further adjustments h = mul * h; if ( h < h_min ) error('Computation with given precision impossible'); end end end result = struct( 'val', previous, 'k', k, 'err', err, 'h', keepH ); end The function in question is: function [ res ] = fun( x, y ) % res(1) = y(2) + y(1) * ( 0.9 - y(1)^2 - y(2)^2 ); res(2) = -y(1) + y(2) * ( 0.9 - y(1)^2 - y(2)^2 ); res = res'; %' end The call is: res = rk4( @fun, [0,20], [0.001; 0.001], 0.008 ); The resulting plot for x1 : The result of ode45( @fun, [0, 20], [0.001, 0.001] ) is:

  • How do I use multiple where clauses in GHCi?

    - by T.R.
    I'm playing around with GHCi for the first time, and I'm having some trouble writing multi-line functions. My code is as follows: Prelude> :{ Prelude| let diffSquares lst = abs $ squareOfSums lst - sumOfSquares lst Prelude| where Prelude| squareOfSums lst = (fst (sumsAndSquares lst))^2 Prelude| sumOfSquares lst = snd (sumsAndSquares lst) Prelude| sumsAndSquares = foldl (\(sms,sqrs) x -> (sms+x,sqrs+x^2)) (0,0) Prelude| :} It gives the following error: <interactive>:1:142: parse error on input `=' Could someone kindly point me in the direction of what I'm missing?

  • Help me understand FFT function (Matlab)

    - by estourodepilha.com
    1) Besides the negative frequencies, which is the minimum frequency provided by the FFT function? Is it zero? 2) If it is zero how do we plot zero on a logarithmic scale? 3) The result is always symmetrical? Or it just appears to be symmetrical? 4) If I use abs(fft(y)) to compare 2 signals, may I lose some accuracy?
