  • Problem with y-axis in Matlab Diagram

    - by Claus
    Hi, I am drawing a simple bar diagram in Matlab. The problem is, that the value at x = 0 lets the y-axis disappear partially. Is there a way to bring the y-axis to the front instead of hiding between the y-value for x=0? Is there any option I can make sure the y-axis is always in the front? Many thanks, Claus

  • Looking for a visualization and charting package

    - by Jeff Meatball Yang
    I have some specific requirements, with the most important at the top: Can plot line and stacked bar charts Can customize mouse events (hover, click) on chart data Compatible and performant with IE7/8 (likely will use excanvas.js) Can optionally control label formats, legends, colors Open source preferred, or at least can purchase the source Can be hosted locally I have seen a couple potentially good ones: Google's interactive charts (But code must be accessed via Google servers) EJSChart Flot Does anyone have experience with these, or others, and can make a recommendation?

  • Python - Get Instance Variables

    - by Chris Bunch
    Is there a built-in method in Python to get an array of all a class' instance variables? For example, if I have this code: class hi: def __init__(self): self.ii = "foo" self.kk = "bar" Is there a way for me to do this: >>> mystery_method(hi) ["ii", "kk"] Thanks guys! Edit: I originally had asked for class variables erroneously. Thanks to all who brought this to my attention!

  • Python: How efficient is subtring extraction?

    - by Cameron
    I've got the entire contents of a text file (at least a few KB) in string myStr. Will the following code create a copy of the string (less the first character) in memory? myStr = myStr[1:] I'm hoping it just refers to a different location in the same internal buffer. If not, is there a more efficient way to do this? Thanks!

  • What is the Null Character literal in TSQL?

    - by David in Dakota
    I am wondering what the literal for a Null character (e.g. '\0') is in TSQL. Note: not a NULL field value, but the null character (see link). I have a column with a mix of typical and a null character. I'm trying to replace the null character with a different value. I would have thought that the following would work but it is unsuccessfull: select REPLACE(field_with_nullchar, char(0), ',') from FOO where BAR = 20

  • wrong operator() overload called

    - by user313202
    okay, I am writing a matrix class and have overloaded the function call operator twice. The core of the matrix is a 2D double array. I am using the MinGW GCC compiler called from a windows console. the first overload is meant to return a double from the array (for viewing an element). the second overload is meant to return a reference to a location in the array (for changing the data in that location. double operator()(int row, int col) const ; //allows view of element double &operator()(int row, int col); //allows assignment of element I am writing a testing routine and have discovered that the "viewing" overload never gets called. for some reason the compiler "defaults" to calling the overload that returns a reference when the following printf() statement is used. fprintf(outp, "%6.2f\t", testMatD(i,j)); I understand that I'm insulting the gods by writing my own matrix class without using vectors and testing with C I/O functions. I will be punished thoroughly in the afterlife, no need to do it here. Ultimately I'd like to know what is going on here and how to fix it. I'd prefer to use the cleaner looking operator overloads rather than member functions. Any ideas? -Cal the matrix class: irrelevant code omitted class Matrix { public: double getElement(int row, int col)const; //returns the element at row,col //operator overloads double operator()(int row, int col) const ; //allows view of element double &operator()(int row, int col); //allows assignment of element private: //data members double **array; //pointer to data array }; double Matrix::getElement(int row, int col)const{ //transform indices into true coordinates (from sorted coordinates //only row needs to be transformed (user can only sort by row) row = sortedArray[row]; result = array[usrZeroRow+row][usrZeroCol+col]; return result; } //operator overloads double Matrix::operator()(int row, int col) const { //this overload is used when viewing an element return getElement(row,col); } double &Matrix::operator()(int row, int col){ //this overload is used when placing an element return array[row+usrZeroRow][col+usrZeroCol]; } The testing program: irrelevant code omitted int main(void){ FILE *outp; outp = fopen("test_output.txt", "w+"); Matrix testMatD(5,7); //construct 5x7 matrix //some initializations omitted fprintf(outp, "%6.2f\t", testMatD(i,j)); //calls the wrong overload }

  • Java api to get windows Special folders

    - by SvrGuy
    I once found a nifty little library that used JNI to allow java applications on Windows to get the locations of various "special" directories on windows. I can't for the life of me find it again... In particular, I need to get the location of the "All Users" (shared) "Application Data" directory. So, anyone have a bullet proof way in Java to locate the "All Users" "Application Data" folder? It needs to be bullet proof.

  • Best way to copy the entire contents of a directory in C#

    - by Keith
    I want to copy the entire contents of a directory from one location to another in C#. There doesn't appear to be a way to do this using System.IO classes without lots of recursion. There is a method in VB that we can use if we add a reference to Microsoft.VisualBasic: new Microsoft.VisualBasic.Devices.Computer(). FileSystem.CopyDirectory( sourceFolder, outputFolder ); This seems like a rather ugly hack. Is there a better way?

  • What are the basics of dealing with user input events in Android?

    - by user279112
    Hello. I thought I had understood this question, but something is quite wrong here. When the user (me, so far) tries to press keys, nothing really happens, and I am having a lot of trouble understanding what it is that I've missed. Consider this before I present some code to help clarify my problem: I am using Android's Lunar Lander example to make my first "real" Android program. In that example, of course, there exist a class LunarView, and class nested therein LunarThread. In my code the equivalents of these classes are Graphics and GraphicsThread, respectively. Also I can make sprite animations in 2D just fine on Android. I have a Player class, and let's say GraphicsThread has a Player member referred to as "player". This class has four coordinates - x1, y1, x2, and y2 - and they define a rectangle in which the sprite is to be drawn. I've worked it out so that I can handle that perfectly. Whenever the doDraw(Canvas canvas) method is invoked, it'll just look at the values of those coordinates and draw the sprite accordingly. Now let's say - and this isn't really what I'm trying to do with the program - I'm trying to make the program where all it does is display the Player sprite at one location of the screen UNTIL the FIRST time the user presses the Dpad's left button. Then the location will be changed to another set position on the screen, and the sprite will be drawn at that position for the rest of the program invariably. Also note that the GraphicsThread member in Graphics is called "thread", and that the SurfaceHolder member in GraphicsThread is called "mSurfaceHolder". So consider this method in class Graphics: @Override public boolean onKeyDown(int keyCode, KeyEvent msg) { return thread.keyDownHandler(keyCode, msg); } Also please consider this method in class GraphicsThread: boolean keyDownHandler(int keyCode, KeyEvent msg) { synchronized (mSurfaceHolder) { if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) { player.x1 = 100; player.y1 = 100; player.x2 = 120; player.y2 = 150; } } return true; } Now then assuming that player's coordinates start off as (200, 200, 220, 250), why won't he do anything different when I press Dpad: Left? Thanks!

  • Why does ASP.Net rewrite relative paths in runat=server anchor controls?

    - by Atomiton
    I have UserControls in a Controls folder in my solution: /Controls/TheControl.ascx If specify the following: <a runat="server" href="./?pg=1">link text</a> ASP.Net seems to want to rewrite the path to point to the absolute location. For example, If the control is on site.com/products/fish/cans.aspx the link href will be rewritten to read <a href="../../Controls/?pg=1 Why does Asp.Net rewrite these control paths, and is there an elegant way to fix it?

  • How to record / capture audio with RecordControl on Java ME, SE K770i

    - by tomaszs
    I want to record sound on my Java ME App on K770i. So I used this: http://java.sun.com/javame/reference/apis/jsr135/javax/microedition/media/control/RecordControl.html example of RecordControl in my code. It goes like this: import java.util.Vector; import javax.microedition.lcdui.Choice; import javax.microedition.lcdui.Command; import javax.microedition.lcdui.CommandListener; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; import javax.microedition.lcdui.List; import javax.microedition.media.Manager; import javax.microedition.media.MediaException; import javax.microedition.midlet.MIDlet; import java.io.*; import javax.microedition.lcdui.*; import javax.microedition.media.*; import javax.microedition.media.control.*; import javax.microedition.midlet.*; import javax.microedition.rms.*; (...) try { // Create a Player that captures live audio. Player p = Manager.createPlayer("capture://audio"); p.realize(); // Get the RecordControl, set the record stream, // start the Player and record for 5 seconds. RecordControl rc = (RecordControl)p.getControl("RecordControl"); ByteArrayOutputStream output = new ByteArrayOutputStream(); rc.setRecordStream(output); rc.startRecord(); p.start(); Thread.currentThread().sleep(5000); rc.commit(); p.close(); } catch (IOException ioe) { } catch (MediaException me) { } catch (InterruptedException ie) { } But unfortunately when I try to build it, it tells me: *** Creating directories *** *** Compiling source files *** ..\src\example\audiodemo\AudioPlayer.java:121: cannot find symbol symbol : class RecordControl location: class example.audiodemo.AudioPlayer RecordControl rc = (RecordControl)p.getControl("RecordControl"); ^ ..\src\example\audiodemo\AudioPlayer.java:121: cannot find symbol symbol : class RecordControl location: class example.audiodemo.AudioPlayer RecordControl rc = (RecordControl)p.getControl("RecordControl"); ^ 2 errors So my question is: why there is no RecordControl class if in documentations it is written this class should be there. Or is there other method to record / capture audio from microfone in Java ME of Sony Ericsson? How do you record sound?

  • PHP upload filename

    - by incrediman
    I'd like to have my PHP script upload a file with a certain filename in a directory of my choosing. However, the catch is that I need it to exist there immediately upon upload so I can moniter it on my server. I don't want to use a PHP extension or something - this should be very easy to transfer to any PHP setup. So basically: Is there a way to guarantee that, from the very beginning of the file upload process, the file has a certain name and location on the server?

  • Convert HTML DOM into a multidimensional array

    - by dclowd9901
    Where keys are represented by element type and values are represented by #foo and .bar (spaced and ready for explode()). Is it possible, or does something exist for it? I know that this question might incite some wrath, and I'm hoping nobody links to that post about parsing HTML, but I'm hoping it's not impossible. Thanks for the help. Addendum: Ideally, PHP would be used, since it's the only scripting language I know.

    I am writing a Sphinx extension and I need to know the document page source code file system path (.rst file location) to extract some version control system information of it. How can I get this information in my event handler / which event handler I should use? Example: # This package may contain traces of nuts def on_html_page_context(app, pagename, templatename, context, doctree): import ipdb ; ipdb.set_trace() if doctree: print doctree.source def setup(app): app.require_sphinx('1.0') app.connect('html-page-context', on_html_page_context)

  • In subform of a MS Access form, how to hide/show the vertical scroll bars as needed?

    - by PowerUser
    I have a subform in an MS Access form which is not hiding/showing the vertical scroll bars as needed. In the example picture, the vertical scroll bar is showing even though there aren't enough records to warrant vertical scrolling. How do I get the scroll bars to show only when they are needed? Do I need to add an if-then condition to the on_load event? or is there an easier option?
