  • easy way to get the top level domain?

    - by Michel
    Hi, i want to get the domain extention (at least i hope it is called this way) from the site name the user is currently on. so from www.bbc.co.uk it's co.uk and www.google.com = .com http://stackoverflow.com/questions/ask = .com etc. especially the ones with the double name (like co.uk) gives me headaches.... EDIT as i understand from the comments, co.uk is not a top level domain? that makes life easier! EDIT new name (top level domain) in the title

  • Custom Visual Studio 2008 Designer

    - by Mick
    How do I create a custom Visual Studio 2008 UI designer for a C# file? For example, when you double click on a DataSet in the Solution Explorer, a UI screen appears that allows you to edit the DataSet, even though it is defined in XML/code (which you can right click and "View Code"). Usually this code is separated from user code in some way, either by region ("Windows Forms Designer Generated Code"), by codegen (".g.cs" for WPF XAML files), or some other means like partial classes.

  • refactoring this function in Java

    - by Joel
    Hi folks, I'm learning Java, and I know one of the big complaints about newbie programmers is that we make really long and involved methods that should be broken into several. Well here is one I wrote and is a perfect example. :-D. public void buildBall(){ /* sets the x and y value for the center of the canvas */ double i = ((getWidth() / 2)); double j = ((getHeight() / 2)); /* randomizes the start speed of the ball */ vy = 3.0; vx = rgen.nextDouble(1.0, 3.0); if (rgen.nextBoolean(.05)) vx = -vx; /* creates the ball */ GOval ball = new GOval(i,j,(2 *BALL_RADIUS),(2 * BALL_RADIUS)); ball.setFilled(true); ball.setFillColor(Color.RED); add(ball); /* animates the ball */ while(true){ i = (i + (vx* 2)); j = (j + (vy* 2)); if (i > APPLICATION_WIDTH-(2 * BALL_RADIUS)){ vx = -vx; } if (j > APPLICATION_HEIGHT-(2 * BALL_RADIUS)){ vy = -vy; } if (i < 0){ vx = -vx; } if (j < 0){ vy = -vy; } ball.move(vx + vx, vy + vy); pause(10); /* checks the edges of the ball to see if it hits an object */ colider = getElementAt(i, j); if (colider == null){ colider = getElementAt(i + (2*BALL_RADIUS), j); } if (colider == null){ colider = getElementAt(i + (2*BALL_RADIUS), j + (2*BALL_RADIUS)); } if (colider == null){ colider = getElementAt(i, j + (2*BALL_RADIUS)); } /* If the ball hits an object it reverses direction */ if (colider != null){ vy = -vy; /* removes bricks when hit but not the paddle */ if (j < (getHeight() -(PADDLE_Y_OFFSET + PADDLE_HEIGHT))){ remove(colider); } } } You can see from the title of the method that I started with good intentions of "building the ball". There are a few issues I ran up against: The problem is that then I needed to move the ball, so I created that while loop. I don't see any other way to do that other than just keep it "true", so that means any other code I create below this loop won't happen. I didn't make the while loop a different function because I was using those variables i and j. So I don't see how I can refactor beyond this loop. So my main question is: How would I pass the values of i and j to a new method: "animateBall" and how would I use ball.move(vx + vx, vy + vy); in that new method if ball has been declared in the buildBall method? I understand this is probably a simple thing of better understanding variable scope and passing arguments, but I'm not quite there yet...

  • What's the fastest way to draw a Hello World in Java

    - by Mordan
    What's the fastest way to draw a Hello World on the screen as a GUI in Java, 1- by using the minimum number of classes. 2- with the least byte code executed 2- the JVM tweaks so when I double click on the Jar file in Windows, the Hello World appears in no time (assuming the Runtime is not already loaded).

  • Qt releasing memory occopied by unneeded images

    - by Gerhman
    I have a QML Flickable with 3 QML image elements that cycle through 8 image files. My problem is for each new image it loads into memory it does not release the the unused image. This is causing memory usage to become double what is necessary at times. I would like to know if there is some function I can use to force it to unload all the unused images? If it makes a difference, this is mainly for Symbian.

  • iPhone Application failing to come back from sigkill

    - by overscore
    I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

  • C++ Change image based on a click (Visual Studio C++)

    - by Jimbo
    In visual studio, when making a C++ windows application form. I want a picture to change when I click on it. So when I double click the picture and it brings up the click action script, what script do I use..... Similiar to int temp = System::Int32::Parse(label1->Text); temp++; label1->Text = temp.ToString(); Which just increments an integer in a label

  • Refactor the following two C++ methods to move out duplicate code

    - by ossandcad
    I have the following two methods that (as you can see) are similar in most of its statements except for one (see below for details) unsigned int CSWX::getLineParameters(const SURFACE & surface, vector<double> & params) { VARIANT varParams; surface->getPlaneParams(varParams); // this is the line of code that is different SafeDoubleArray sdParams(varParams); for( int i = 0 ; i < sdParams.getSize() ; ++i ) { params.push_back(sdParams[i]); } if( params.size() > 0 ) return 0; return 1; } unsigned int CSWX::getPlaneParameters(const CURVE & curve, vector<double> & params) { VARIANT varParams; curve->get_LineParams(varParams); // this is the line of code that is different SafeDoubleArray sdParams(varParams); for( int i = 0 ; i < sdParams.getSize() ; ++i ) { params.push_back(sdParams[i]); } if( params.size() > 0 ) return 0; return 1; } Is there any technique that I can use to move the common lines of code of the two methods out to a separate method, that could be called from the two variations - OR - possibly combine the two methods to a single method? The following are the restrictions: The classes SURFACE and CURVE are from 3rd party libraries and hence unmodifiable. (If it helps they are both derived from IDispatch) There are even more similar classes (e.g. FACE) that could fit into this "template" (not C++ template, just the flow of lines of code) I know the following could (possibly?) be implemented as solutions but am really hoping there is a better solution: I could add a 3rd parameter to the 2 methods - e.g. an enum - that identifies the 1st parameter (e.g. enum::input_type_surface, enum::input_type_curve) I could pass in an IDispatch and try dynamic_cast< and test which cast is NON_NULL and do an if-else to call the right method (e.g. getPlaneParams() vs. get_LineParams()) The following is not a restriction but would be a requirement because of my teammates resistance: Not implement a new class that inherits from SURFACE/CURVE etc. (They would much prefer to solve it using the enum solution I stated above)

  • What does explorer use to open a file?

    - by dauphic
    I'm attempting to hook into whatever explorer calls when a file is opened (double-click, context menu open, etc.), however I can't figure out which function that is. Originally, I thought it was ShellExecute, as that does the same thing as far as I can tell, but after hooking into it I learned that it's only used when a new explorer window is opened. Any ideas which function I should be hooking?

  • Telephone Directory

    - by Mizukage of Meron 5
    I need your help. We are ask to make a telephone directory program that asks your name, address, and telephone number. If the name you entered already exists, it will display that it already exists. This is what i have so far... #include<stdio.h> #include<conio.h> struct file { char name[25],address[25]; double telno; }; char tempname[25],tempadd[25]; double tempnum; int x; int choice; FILE *fp; main() { struct file rec; clrscr(); fp=fopen("TelDir.txt","a+"); while(!feof(fp)) { fscanf(fp,"%s %s %.0lf,&tempname,&tempadd,&tempnum); printf("\n%s\t\t%s\t\t\t%.0lf",tempname,tempadd,tempnum); printf("\nEnter Name: "); gets(rec.name); if(strcmp(rec.name,tempname)==1) { printf("\n\nALREADY EXIST!"); printf("\n%s\t\t%s\t\t\t%.0lf",tempname,tempadd,tempnum); getch(); } else { printf("Enter Address: "); scanf("%s",&rec.address); printf("Enter your Telephone No.: "); scanf("%lf",&rec.telno); printf("%s\t\t%s\t\t%\t\t0lf",rec.name,rec.address,rec.telno); fprintf(fp,"%s %s %.0lf\n",rec.name,rec.address,rec.telno); } } fclose(fp); getch(); } But this thing doesn't work. I don't know where the error is. Can someone help me on this? I would really appreciate if you could help me somehow.

  • Money vs. Decimal vs. Float Performance issues (SQL data types for Currency value)?

    - by urz shah
    What data type should be selected in case of Currency value column in SQL server. I have read some where on web Working on customer implementations, we found some interesting performance numbers concerning the money data type. For example, when Analysis Services was set to the currency data type (from double) to match the SQL Server money data type, there was a 13% improvement in processing speed (rows/sec). Is it true??

  • How can I associate .sh files with Cygwin?

    - by Jerph
    I'd like to run a long rsync command in Cygwin by double clicking on a .sh file in Windows. It must start in the file's containing directory (e.g. /cygdrive/c/scripts/) so that relative paths work. Anyone gotten this to work? Note: I've just found chere, a Cygwin package that manages Windows context menus (Bash Prompt Here). It might have some clues.

  • Web UI for inputting a function from the reals to the reals, such as a probability distribution.

    - by dreeves
    I would like a web interface for a user to describe a one-dimensional real-valued function. I'm imagining the user being presented with a blank pair of axes and they can click anywhere to create points that are thick and draggable. Double-clicking a point, let's say, makes it disappear. The actual function should be shown in real time as an interpolation of the user-supplied points. Here's what this looks like implemented in Mathematica (though of course I'm looking for something in javascript):

  • C# Console Program Won't Execute from Command Prompt

    - by user1656066
    I have made a very simple program in C#. When I double click the compiled exe, it executes and works. When I run the exe from the command prompt, it does absolutely nothing. I have tried executing it from an Administrator command prompt also. I am on Windows 7. This is very frustrating. The only command the program executes when ran is SendMessageW(Process.GetCurrentProcess().MainWindowHandle, WM_APPCOMMAND, Process.GetCurrentProcess().MainWindowHandle, (IntPtr)APPCOMMAND_VOLUME_MUTE);

    Can someone please help me with this preg_match if (preg_match('~[^A-Za-z0-9_\./\]~', $filepath)) // Show Error message. I need to match a possible filepath. So I need to check for double slashes, etc. Valid file path strings should look like this only: mydir/aFile.php or mydir/another_dir/anyfile.js So a slash at the beginning of this string should be checked also. Please help. Thanks :)
