  • Changing Emacs Forward-Word Behaviour

    - by gvkv
    As the title says, how does one change the behaviour of emacs forward-word function? For example, suppose [] is the cursor. Then: my $abs_target_path[]= abs_path($target); <M-f> my $abs_target_path = abs[_]path($target); I know I could just use M-f M-b but as far as I'm concerned, that shouldn't be necessary and I'd like to change it. In particular, I want two things: When I press M-f, I want to go to the first character of the next word regardless of whether the point is within a word, within a group of spaces or somewhere else. Customize word-characters on a mode-by-mode basis. After all, moving around in CPerl mode is different than, say, TeX mode. So, in the above example, item 1 would have the cursor would move to the 'a' (and the point to it's left) after hitting M-f. Item 2 would allow me to define underscores and sigils as word characters.

  • Javascript resizing with window.open and WebBrowser control

    - by Raj
    I'm using WPF WebBrowser control and handling NewWindow3 events using following code: IServiceProvider serviceProvider = (IServiceProvider)webBrowser.Document; Guid serviceGuid = SID_SWebBrowserApp; Guid iid = typeof(SHDocVw.WebBrowser).GUID; SHDocVw.WebBrowser wb = (SHDocVw.WebBrowser)serviceProvider.QueryService(ref serviceGuid, ref iid); wb.NewWindow3 += new SHDocVw.DWebBrowserEvents2_NewWindow3EventHandler(wb_NewWindow3); How to handle javascript resizing when navigating using window.open, something like this: window.open('Sample.htm',null,'height=200,width=400,status=yes,toolbar=no,menubar=no,location=no'); Is there anyway to get height and width requested by caller in NewWindow3 event handler?

  • Getting really weird long Contact Group names

    - by Pentium10
    When looking at the Contact Groups on Google Contacts or in the People application of my HTC Legend phone, I get the groups names ok eg: Friends, Family, VIP, Favorite etc... But in my application I get really wrong names such as "Family" became "System Group: Family" "Friends" became "System Group: Friends" "Favorite" became "Favorite_5656100000000_3245664334564" I use the below code to read these values: public Cursor getFromSystem() { // Get the base URI for the People table in the Contacts content // provider. Uri contacts = ContactsContract.Groups.CONTENT_URI; // Make the query. ContentResolver cr = ctx.getContentResolver(); // Form an array specifying which columns to return. String[] projection = new String[] { ContactsContract.Groups._ID, ContactsContract.Groups.TITLE, ContactsContract.Groups.NOTES }; Cursor managedCursor = cr.query(contacts, projection, ContactsContract.Groups.DELETED + "=0", null, ContactsContract.Groups.TITLE + " COLLATE LOCALIZED ASC"); return managedCursor; } What I am missing?

  • How do I change a Git remote HEAD to point to something besides "master"

    - by jhs
    Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.

  • CSharp -- PInvokeStackImbalance detected on a well documented function?

    - by Aaron Hammond
    Here is my code for a ClickMouse() function: [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo); private const long MOUSEEVENTF_LEFTDOWN = 0x02; private const long MOUSEEVENTF_LEFTUP = 0x04; private const long MOUSEEVENTF_RIGHTDOWN = 0x08; private const long MOUSEEVENTF_RIGHTUP = 0x10; private void ClickMouse() { long X = Cursor.Position.X; long Y = Cursor.Position.Y; mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0); } For some reason, when my program comes to this code, it throws this error message: PInvokeStackImbalance was detected Message: A call to PInvoke function 'WindowsFormsApplication1!WindowsFormsApplication1.Form1::mouse_event' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature. Please help?

  • Starting ActiveMQ message listener in Tomcat?

    - by Nick Swarr
    I've created an ActiveMQ MessageListener and configured it using Spring. I'm hosting the listener in Tomcat. When I start up the web application (that features only the listener), should the listener automatically start? Or do I need additional configuration? Here's what I have. First, updated the web.xml to allow spring to configure itself on startup, <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/spring/applicationContext.xml</param-value> </context-param> </web-app> Then I created the applicationContext.xml to configure the ActiveMQ listener, <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.somepackage"/> <context:property-placeholder location="classpath:env.properties"/> <bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="documentListener" class="com.somepackage.SomeListener" /> <bean id="container" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="cachingConnectionFactory"/> <property name="messageListener" ref="documentListener"/> <property name="destinationName" value="STOCKS.MSFT" /> </bean> <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="jmsFactory" /> <property name="sessionCacheSize" value="1" /> </bean> </beans> And that's it. Based on what I've seen around the web, I can't tell if that's all I need? Maybe I need some other configuration in Tomcat to kick off the listener?

  • Help with complex sql query

    - by eugeneK
    To make story short, i'm building self-learning banner management system. Users will be able to insert these banners to their site when banners will be shown based on sales/impressions ratio. I have 4 tables Banners bannerID int bannerImage varchar.... SmartBanners smartBannerID int smartBannerArrayID int bannerID int impressionsCount int visibility tinyint (percents) SmartBannerArrays smartBannerArrayID int userID int Statistics bannerID int saleAmountPerDay decimal... Each night i need to generate new "visibility" for each SmartBanner based on whole SmartBannerArray that same user has. So i need to get sum of impressions and sales for each bannerID in SmartBannerArray. All comes to my mind is to use double cursor, one will loop thought SmartBannerArrays get needed values for sum of impressions and sales and then inner loop which will access each SmartBanner and change it's "visibility" percentage based on (sales/impressions)/(sumOfSales/sumOfImpressions)*100 Hope you get the picture... Is there any other way to design better tables or not to use double cursor to avoid server overload ?

  • DynamicMethod NullReferenceException

I get a NullReferenceException. My DynamicMethod's signature is: public delegate void DynamicWrite(IMyXmlWriter writer, ref object value, MyContract contract); And I'm definitely not passing in anything null. Thanks in advance!

  • Assignments failing

    - by Andrei Krotkov
    I'm debugging part of a large project in Visual Studio 2005, and stepping through the code line by line. int speed = this->values.speed; int ref = this->values.ref_speed; After stepping past the first line, values.speed has a value of 61, but for some reason, speed is getting assigned the value 58. After the second line, values.ref_speed has a value of 58, but ref gets assigned the value 30. When paused, you can see that the original values are in fact 61 and 58 respectively, but the values getting stored are different. What is causing this behaviour?

  • How can I make my Perl Jabber bot an event-driven program?

    - by TheGNUGuy
    I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run?

  • Constraining window position to desktop working area

    - by simplecoder
    I want to allow a user to drag my Win32 window around only inside the working area of the desktop. In other words, they shouldn't be able to have any part of the window extend outside the monitor(s) nor should the window overlap the taskbar. I'd like to do it in a way that does cause any stuttering. Handling WM_MOVE messages and calling MoveWindow() to reposition the window if it goes off works, but I don't like the flickering effect that's caused by MoveWindow(). I also tried handling WM_MOVING which prevents the need to call MoveWindow() by altering the destination rectangle before the move actually happens. This resolves the flickering problem, but another issue I run into is that the cursor some times gets aways from the window when a drag occurs allowing the user to drag the window around while the cursor is not even inside the window. How do I constrain my window without running into these issues?

  • C# problem with two threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • Disable keyboard on EditText

    - by Ferox
    I'm doing a calculator. So I made my own Buttons with numbers and functions. The expression that has to be calculated, is in an EditText, because I want users can add numbers or functions also in the middle of the expression, so with the EditText I have the cursor. But I want to disable the Keyboard when users click on the EditText. I found this example that it's ok for Android 2.3, but with ICS disable the Keyboard and also the cursor. public class NoImeEditText extends EditText { public NoImeEditText(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onCheckIsTextEditor() { return false; } } And then I use this NoImeEditText in my XML file <com.my.package.NoImeEditText android:id="@+id/etMy" .... /> How I can make compatible this EditText with ICS??? Thanks.

  • Why is the destructor called when the CPython garbage collector is disabled?

    - by Frederik
    I'm trying to understand the internals of the CPython garbage collector, specifically when the destructor is called. So far, the behavior is intuitive, but the following case trips me up: Disable the GC. Create an object, then remove a reference to it. The object is destroyed and the __del__ method is called. I thought this would only happen if the garbage collector was enabled. Can someone explain why this happens? Is there a way to defer calling the destructor? import gc import unittest _destroyed = False class MyClass(object): def __del__(self): global _destroyed _destroyed = True class GarbageCollectionTest(unittest.TestCase): def testExplicitGarbageCollection(self): gc.disable() ref = MyClass() ref = None # The next test fails. # The object is automatically destroyed even with the collector turned off. self.assertFalse(_destroyed) gc.collect() self.assertTrue(_destroyed) if __name__=='__main__': unittest.main() Disclaimer: this code is not meant for production -- I've already noted that this is very implementation-specific and does not work on Jython.

  • Problem with virtual mouse click

For example I call this function every 30 minutes. But if I press WINKEY+L (Windows is locked) only cursor is moved but not press occurs. Any ideas?
