  • Help with this reg. exp. in PHP

    - by Jonathan
    Hi, i don't know about regular expressions, I asked here for one that: gets either anything up to the first parenthesis/colon or the first word inside the first parenthesis. This was the answer: preg_match('/(?:^[^(:]+|(?<=^\\()[^\\s)]+)/', $var, $match); I need an improvement, I need to get either anything up to the first parenthesis/colon/quotation marks or the first word inside the first parenthesis. So if I have something like: $var = 'story "The Town in Hell"s Backyard'; // I get this: $match = 'story'; $var = "screenplay (based on)"; // I get this: $match = 'screenplay'; $var = "(play)"; // I get this: $match = 'play'; $var = "original screen"; // I get this: $match = 'original screen'; Thanks!

  • Quartz 2D animating text?

    - by coure06
    i have to animate text around a circle. The text will also scale up/down. Whats the best approach to accomplish this? (i am using Quartz 2D) My approach is: -- Calculate point using sin and cos methods. -- Move Pen there and draw text with alpha and size. -- Clear the screen -- Calculate next point using sin and cos methods. -- Move pen there and draw text with alpha and size. -- clear the screen so on... any better way?

  • Printing complex widgets in Qt

    - by Jens
    I have a complex widget with tons of different subwidgets, e.g. subclasses of QLabel. I want to print this widget, but obviously I do not want to print the background, I want to print with differing text colors or have the style of frames slightly modified. As I do not really want to iterate through all subwidgets with a special "print" function, which I would need to attach to all widgets (how to add "print" to a QLabel?), I would like to use paintEvent. If I have a hierarchy MyWidget - derived from - some QWidget, I would like to insert a sublayer MyWidget - MyPrintWidget - some QWidget, where myPrintWidget::paintEvent would check, if the current print is going to the screen (thus call QWidget::paintEvent), else if we are printing to the printer, call some function MyPrintWidget::drawWidget instead. Is this the right way to print-enable a widget? How can I figure out in paintEvent, that I'm printing to a printer instead of the screen? Is there a good example of printing complex widgets?

  • detect if extended desktop is to the left or to the right

    - by bobobobo
    So, I have a screen capture utility (it takes full screen shots and saves it to png files) I've written, and it uses SM_CXVIRTUALSCREEN and SM_CYVIRTUALSCREEN to determine the width and height of the desktop. I then get the desktop DC and copy out the bits and save them as png. BitBlt( backDC, 0, 0, backBufferCX, backBufferCX, desktopDC, X_SRC, 0, SRCCOPY ); Here X_SRC is usually 0, UNLESS THE DESKTOP HAS BEEN EXTENDED "TO THE LEFT". In that case it needs to be -1280px, for example, if the left monitor measures 1280px. How can I determine if the desktop's starting point is negative (if the user has extended his desktop to the left?)

  • ncurses - expect: sleep executes at wrong time

    - by rahul
    I have some ncurses apps that I need to automate to test repeatedly. I am placing the "sleep" command between "send" commands. However, what i see is that all the sleep's are executed in the beginning before the screen loads. expect concatenates the sends (I see that at the screen bottom during sleep) then issues them together. I have tried sending all keys with "send -s" or "send -h". That marginally helps. I've replaced "-f" on line 1 with "-b" - again a tiny difference. Why isn't "sleep" pausing at the right time. Incidentally, my programs have a getc() loop, so i can't use "expect" command. I tried that too. #!/usr/bin/expect -f spawn ruby testsplit.rb #expect set send_human {3 3 5 5 7} set send_slow {10 1} exp_send -s -- "--" exec sleep 3 send -s "+" send -s "=" sleep 1 send -h -- "-" send -h -- "-" sleep 1 send -h -- "v" interact

  • Java long task - Did it stop writing to file?

    - by rockit
    I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

  • JPanels, JFrames, and Windows, Oh my!

    - by Jonathan
    Simply stated, I am trying to make a game I am working on full-screen. I have the following code I am trying to use: GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gs = ge.getDefaultScreenDevice(); if(!gs.isFullScreenSupported()) { System.out.println("full-screen not supported"); } Frame frame = new Frame(gs.getDefaultConfiguration()); Window win = new Window(frame); try { // Enter full-screen mode gs.setFullScreenWindow(win); win.validate(); } Problem with this is that I am working within a class that extends JPanel, and while I have a variable of type Frame, I have none of type Window within the class. My understanding of JPanel is that it is a Window of sorts, but I cannot pass 'this' into gs.setFullScreenWindow(Window win)... How should I go about doing this? Is there any easy way of calling that, or a similar method, using a JPanel? Is there a way I can get something of type Window from my JPanel? - EDIT: The following method changes the state of JFrame and is called every 10ms: public void paintScreen() { Graphics g; try{ g = this.getGraphics(); //get Panel's graphic context if(g == null) { frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setExtendedState(frame.getExtendedState()|JFrame.MAXIMIZED_BOTH); frame.add(this); frame.pack(); frame.setResizable(false); frame.setTitle("Game Window"); frame.setVisible(true); } if((g != null) && (dbImage != null)) { g.drawImage(dbImage, 0, 0, null); } Toolkit.getDefaultToolkit().sync(); //sync the display on some systems g.dispose(); } catch (Exception e) { if(blockError) { blockError = false; } else { System.out.println("Graphics context error: " + e); } } } I anticipate that there may be a few redundancies or unnecessary calls after the if(g==null) statement (all the frame.somethingOrOther()s), any cleanup advice would be appreciated... Also, the block error is what it seems. I am ignoring an error. The error only occurs once, and this works fine when setup to ignore the first instance of the error... For anyone interested I can post additional info there if anyone wants to see if that block can be removed, but i'm not concerned... I might look into it later.

    - by RRB

  • Disable the Go button in the Keyboard for a UITextfield in iphone app.

    - by coder net
    Hi, My app has a screen where keyboard is always visible. The main element of the screen is a UITextfield. For easy data entering, keyboard is always made visible. When the user finishes entering data and hits Go, the app performs a 4,5 seconds action which is done in the background thread in order to show UIActivityIndicatorView. My problem is that the Go button on the keyboard still shows as enabled since the logic is performed in the background. The user could potentially hit the Go again causing it to run again. I am not able to set editable/userinteraction properties to No because then the keyboard disappears. Is there anyway just to disable the Go button or freeze the keyboard until the background thread returns?

  • Unlock device, display a text, then lock again

    - by Waza_Be
    For the need of my application, I need to display a message on the screen even if the lockscreen is enabled, then wait 3 seconds, than I have to lock again the phone as I don't want it to make unwanted phone calls in your pockets. First part is easy: if (PreferenceManager.getDefaultSharedPreferences( getBaseContext()).getBoolean("wake", false)) { KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode(); WakeLocker.acquire(ProtoBenService.this); Intent myIntent = new Intent(ProtoBenService.this,LockActivity.class); myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (isKeyguardUp) { ProtoBenService.this.startActivity(myIntent); } else Toast.makeText(ProtoBenService.this.getBaseContext(), intention, Toast.LENGTH_LONG).show(); WakeLocker.release(); } With this class: public abstract class WakeLocker { private static PowerManager.WakeLock wakeLock; public static void acquire(Context ctx) { if (wakeLock != null) wakeLock.release(); PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "CobeIm"); wakeLock.acquire(); } public static void release() { if (wakeLock != null) wakeLock.release(); wakeLock = null; } } And the Activity: public class LockActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Window window = getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); TextView tv = new TextView(this); tv.setText("This is working!"); tv.setTextSize(45); setContentView(tv); Runnable mRunnable; Handler mHandler = new Handler(); mRunnable = new Runnable() { @Override public void run() { LockActivity.this.finish(); } }; mHandler.postDelayed(mRunnable, 3 * 1000); } } So, this is nice, the phone can display my text! The only problem comes when I want to lock again the phone, it seems that locking the phone is protected by the system... Programmatically turning off the screen and locking the phone how to lock the android programatically I think that my users won't understand the Device Admin and won't be able to activate it. Is there any workaround to lock the screen without the Device Admin stuff?

  • [Android] Weird black line on top of list view

    - by CaseyB
    I am creating a layout with a ListView and at the very top of the list there is this weird black line that I can't seem to figure out how to get rid of! It's part of the ListView because it moves up and down as I size the ListView. Has anyone ran into this before? I couldn't get DDMS to take a screen capture for some reason so I took a picture of the screen with my G1, so please forgive the quality! As you can see the line is there at the top of the fade out in the list.

  • in jqgrid, how can i have the editform disappear after submit

    - by leora
    right now, when i click submit it sends a message to the server and updates the databased and refreshes the screen but it keeps the edit form popup on the screen. Is there anyway to have it disappear once the submit is complete. its kind of annoying because its a little unclear that you are done because the form just sits there (even through the grid has refreshed) i have closeAfterEdit and closeAfterAdd set to true but it doesn't seem to do anything. jQuery("#grid").navGrid("#pager", { }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterEdit: true, url: siteRoot + controller + "/Update" }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterAdd: true, url: siteRoot + controller + "/Add" }, { reloadAfterSubmit: true, url: siteRoot + controller + "/Delete" }, { multipleSearch: true }

    - by Daniel Granger
    I have an edit view in my app which is a instance of UITableViewController and contains one cell with a textfield in a grouped table. At the moment this cell is at the top of the screen and is firstResponder so they keyboard is visible as well. But in all the Apples apps like the Contacts App when you edit a piece of information like an Email it buts both of its rows in the middle between the Nav Bar and the Keyboard not at the top of the screen. How do I achieve this effect? Many Thanks

  • Configuring 2 XBee Modules on OSX for wireless connection

    - by Annette
    I am trying find out how and with which program for OSX (10.5.8) I can configure serial ports? I am trying to establish a wireless connection between two Xbee´s (RF modules) and cannot figure out how to use ZTerm nor screen under Terminal. The setup I am using is: an Arduino+Xbeeshield+Xbee with external power supply, and an xbee on the xbee explorer connected to the Computer via USB. I am trying to gather information on this through various forums, but most of them cover the configuration issue for PC using X-CTU (which I tried with CrossOver but it doesn´t recognize ny of my ports). According to one source, using screen under Terminal should show me all my serial ports, particularly /dev/tty.KeySerial1 - but it doesn´t show, even though I´ve plugged in both my arduino+xbee shield and the xbee on the explorer.

  • how to animate a menu item into a large div (window) using jquery's animate?

    - by ijjo
    i'm pretty sure this can be done pretty easily with jquery's animate api, but i'm not good enough to figure it out. what i want to do is this: i have a menu item at the top of the viewport that the user will click on. when the user clicks on it, you'll see something that looks like the div "popping" out of the menu and float to a particular location on the screen. when i say popping i don't mean anything fancy - i just mean it appears to be originating from the menu item and settling somewhere on the screen that i specify. but the important part is that this animation happens really fast. fast enough where you don't have to actually wait for the window to appear, but slow enough so the eye sees the animation start from the menu item and end up at a new location where the window will actually appear, and appear with a specify height and width. hope that all made sense?

  • How to close a form in UserControl

    - by FJPoort
    I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?

  • C++ SDL State Machine Segfault

    The code compiles and builds fine, but it immediately segfaults. I've looked at this for a while and have no idea why. Any help is appreciated. Thank you!
