  • HTML onmouseover doesn't work to show up text

    - by REALFREE
    I'm trying to show some information on a picture when onmouseover/onmouseout event occurs. What I want to achieve is something like this website does on top selling. My code is like this: <div class="container" onmouseover="$('#info').css('display','block');" onmouseout="$('#info').css('display','none');"> <img src=..."> <div id="info" style="display:none"> ... some text ... </div> </div> So div info block is initially hidden, but when mouse is on a picture I want the information to appear on corresponding picture (with tint background on the image to see text well). But somewhat it doesn't work. I appreciate any suggestion how to approach this problem. Edit: more precisely, the reason why I choose to use inline because I need to show/hide text corresponding to the image(contain unique div id)that user put their mouse on/out. That means I have many div container and each container has unique div id.

  • Getting DirectoryNotFoundException when trying to Connect to Device with CoreCon API

    - by ageektrapped
    I'm trying to use the CoreCon API in Visual Studio 2008 to programmatically launch device emulators. When I call device.Connect(), I inexplicably get a DirectoryNotFoundException. I get it if I try it in PowerShell or in C# Console Application. Here's the code I'm using: static void Main(string[] args) { DatastoreManager dm = new DatastoreManager(1033); Collection<Platform> platforms = dm.GetPlatforms(); foreach (var p in platforms) { Console.WriteLine("{0} {1}", p.Name, p.Id); } Platform platform = platforms[3]; Console.WriteLine("Selected {0}", platform.Name); Device device = platform.GetDevices()[0]; device.Connect(); Console.WriteLine("Device Connected"); SystemInfo info = device.GetSystemInfo(); Console.WriteLine("System OS Version:{0}.{1}.{2}", info.OSMajor, info.OSMinor, info.OSBuildNo); Console.ReadLine(); } My question: Does anyone know why I'm getting this error? I'm running this on WinXP 32-bit, plain jane Visual Studio 2008 Pro. I imagine it's some config issue since I can't do it from a Console app or PowerShell. Here's the stack trace as requested: System.IO.DirectoryNotFoundException was unhandled Message="The system cannot find the path specified.\r\n" Source="Device Connection Manager" StackTrace: at Microsoft.VisualStudio.DeviceConnectivity.Interop.ConManServerClass.ConnectDevice() at Microsoft.SmartDevice.Connectivity.Device.Connect() at ConsoleApplication1.Program.Main(String[] args) in C:\Documents and Settings\Thomas\Local Settings\Application Data\Temporary Projects\ConsoleApplication1\Program.cs:line 23 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException:

  • Crystal Reports Failed Database Login

    - by Marlon
    Hello, After spending a good 3 to 4 hours on google trying to find any solution to my problem I haven't had much luck. Basically, we use crystal reports for our .NET applications with a sql server back end, we have many clients each with their own server and so our reports need to have their connections dynamically set. Up until a week ago this worked fine. However a few days ago a client reported they were getting a database login prompt for a report (only one report, the rest worked fine). We were quite stumped but we managed to reproduce it on a netbook which didn't have visual studio or sql server installed. In the end the dev decided to reproduce the report in the hope it was just an oddity in that particular report. Unfortunately a new client today also experienced the same problem, but this time for every crystal report they had - and also they worked on the netbook, so we are really quite lost here. Below is a screenshot of what our clients get presented with - and here is the code that I use to set the connection information in the report cI.ServerName = (string)builder["Data Source"]; cI.DatabaseName = (string)builder["Initial Catalog"]; cI.UserID = (string)builder["User ID"]; cI.Password = (string)builder["Password"]; foreach (IConnectionInfo info in cryRpt.DataSourceConnections) { info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password); } foreach (ReportDocument sub in cryRpt.Subreports) { foreach (IConnectionInfo info in sub.DataSourceConnections) { info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password); } } As always, any help much appreciated.

  • cannot override a concrete member without a third member that's overridden by both

    - by huynhjl
    What does the following error message mean? cannot override a concrete member without a third member that's overridden by both (this rule is designed to prevent ``accidental overrides''); I was trying to do stackable trait modifications. It's a little bit after the fact since I already have a hierarchy in place and I'm trying to modify the behavior without having to rewrite a lot of code. I have a base class called AbstractProcessor that defines an abstract method sort of like this: class AbstractProcessor { def onPush(i:Info): Unit } I have a couple existing traits, to implement different onPush behaviors. trait Pass1 { def onPush(i:Info): Unit = { ... } } trait Pass2 { def onPush(i:Info): Unit = { ... } } So that allows me to use new AbstractProcessor with Pass1 or new AbstractProcessor with Pass2. Now I would like to do some processing before and after the onPush call in Pass1 and Pass2 while minimizing code changes to AbstractProcessor and Pass1 and Pass2. I thought of creating a trait that does something like this: trait Custom extends AbstractProcessor { abstract override def onPush(i:Info): Unit = { // do stuff before super.onPush(i) // do stuff after } And using it with new AbstractProcessor with Pass1 with Custom and I got that error message.

  • Detect NetStream events with AS3 Video Object (not component)

    - by JFOX
    I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video. Video embed code: // Initialize net stream nc = new NetConnection(); nc.connect (null); // Not using a media server. ns = new NetStream(nc); // Add video to stage vid = new Video(456,675); addChild (vid); // Add callback method for listening on // NetStream meta data client = new Object(); ns.client = client; client.onMetaData = this.nsMetaDataCallback; client.onCuePoint = this.onCuePoint; // Play video vid.attachNetStream ( ns ); ns.play ("flv/00_010.flv"); callback handlers in the same class as the above code: public function onCuePoint(info:Object):void { trace("cuePoint: time = " + info.time + " name = " + info.name + " type = " + info.type); if (ns) ns.pause(); } public function nsMetaDataCallback (mdata:Object):void { trace (mdata.duration); } Is there anything I am missing have wrong to capture events from my net stream?

    Hi, I have a static generic dictionary in a class. As static memeber cannot serialized so i have implented ISerializable interface and method GetObjectData to serialize. I have a constructor which will also accept SerializationInfo and StreamingContext to deserliaze the dictionay. Now when i try to serialize and deserialize , it always return 1(thoug i added 2 entries). please find the pseduo code- [Serializable] public class MyClass : ISerializable { internal static Dictionary<long, string> dict = new Dictionary<long,string>(); public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("static.dic", MyClass1.dict, typeof(Dictionary<long, string>)); } public MyClass(SerializationInfo info, StreamingContext context) { MyClass.dict= (Dictionary<long, string>)info.GetValue("static.dic", typeof(Dictionary<long, string>)); } public void Add() { dict.Add(21, "11"); } public MyClass() { dict.Add(21, "11"); } } public class MyClass { MyClass myClass = new MyClass(); public static void Main() { myClass.Add(); FileStream fileStream = new FileStream("test.binary", FileMode.Create); IFormatter bf = new BinaryFormatter(); bf.Serialize(fileStream, myClass); fileStream.Dispose(); fileStream.Close(); fileStream = new FileStream("test.binary", FileMode.Open); bf = new BinaryFormatter(); myClass = (MyClass1)bf.Deserialize(fileStream); } }

  • Running Solr on VPS problems

    - by Camran
    I have a VPS with Ubuntu OS. I run solr om my local machine (windows xp laptop) just fine. I have configured Jetty, and Solr just the same way as on my computer, but on the server. I have also downloaded the JRE and installed it on the server. However, whenever I try to run the start.jar file, the PuTTY terminal shows a bunch of text but gets stuck. I could pase the text here but it is very long, so unless somebody wants to see it I wont. Also, I cant view the solr admin page at all. Does anybody have experience in this kind of problem? Maybe java isn't correctly installed? It is a VPS so maybe installation is different. Thanks UPDATE: These are the last lines from the terminal, in other words, this is where it stops every time: INFO: [] webapp=null path=null params={event=firstSearcher&q=static+firstSearcher+warming+query+from+solrconfig.xml} hits=0 status=0 QTime=9 May 28, 2010 8:58:42 PM org.apache.solr.core.QuerySenderListener newSearcher INFO: QuerySenderListener done.

  • Closing a hook that captures global input events

    - by Margus
    Intro Here is an example to illustrate the problem. Consider I am tracking and displaying mouse global current position and last click button and position to the user. Here is an image: To archive capturing click events on windows box, that would and will be sent to the other programs event messaging queue, I create a hook using winapi namely user32.dll library. This is outside JDK sandbox, so I use JNA to call the native library. This all works perfectly, but it does not close as I expect it to. My question is - How do I properly close following example program? Example source Code below is not fully written by Me, but taken from this question in Oracle forum and partly fixed. import java.awt.AWTException; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.GridLayout; import java.awt.MouseInfo; import java.awt.Point; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.JFrame; import javax.swing.JLabel; import com.sun.jna.Native; import com.sun.jna.NativeLong; import com.sun.jna.Platform; import com.sun.jna.Structure; import com.sun.jna.platform.win32.BaseTSD.ULONG_PTR; import com.sun.jna.platform.win32.Kernel32; import com.sun.jna.platform.win32.User32; import com.sun.jna.platform.win32.WinDef.HWND; import com.sun.jna.platform.win32.WinDef.LRESULT; import com.sun.jna.platform.win32.WinDef.WPARAM; import com.sun.jna.platform.win32.WinUser.HHOOK; import com.sun.jna.platform.win32.WinUser.HOOKPROC; import com.sun.jna.platform.win32.WinUser.MSG; import com.sun.jna.platform.win32.WinUser.POINT; public class MouseExample { final JFrame jf; final JLabel jl1, jl2; final CWMouseHook mh; final Ticker jt; public class Ticker extends Thread { public boolean update = true; public void done() { update = false; } public void run() { try { Point p, l = MouseInfo.getPointerInfo().getLocation(); int i = 0; while (update == true) { try { p = MouseInfo.getPointerInfo().getLocation(); if (!p.equals(l)) { l = p; jl1.setText(new GlobalMouseClick(p.x, p.y) .toString()); } Thread.sleep(35); } catch (InterruptedException e) { e.printStackTrace(); return; } } } catch (Exception e) { update = false; } } } public MouseExample() throws AWTException, UnsupportedOperationException { this.jl1 = new JLabel("{}"); this.jl2 = new JLabel("{}"); this.jf = new JFrame(); this.jt = new Ticker(); this.jt.start(); this.mh = new CWMouseHook() { @Override public void globalClickEvent(GlobalMouseClick m) { jl2.setText(m.toString()); } }; mh.setMouseHook(); jf.setLayout(new GridLayout(2, 2)); jf.add(new JLabel("Position")); jf.add(jl1); jf.add(new JLabel("Last click")); jf.add(jl2); jf.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent we) { mh.dispose(); jt.done(); jf.dispose(); } }); jf.setLocation(new Point(0, 0)); jf.setPreferredSize(new Dimension(200, 90)); jf.pack(); jf.setVisible(true); } public static class GlobalMouseClick { private char c; private int x, y; public GlobalMouseClick(char c, int x, int y) { super(); this.c = c; this.x = x; this.y = y; } public GlobalMouseClick(int x, int y) { super(); this.x = x; this.y = y; } public char getC() { return c; } public void setC(char c) { this.c = c; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } @Override public String toString() { return (c != 0 ? c : "") + " [" + x + "," + y + "]"; } } public static class CWMouseHook { public User32 USER32INST; public CWMouseHook() throws UnsupportedOperationException { if (!Platform.isWindows()) { throw new UnsupportedOperationException( "Not supported on this platform."); } USER32INST = User32.INSTANCE; mouseHook = hookTheMouse(); Native.setProtected(true); } private static LowLevelMouseProc mouseHook; private HHOOK hhk; private boolean isHooked = false; public static final int WM_LBUTTONDOWN = 513; public static final int WM_LBUTTONUP = 514; public static final int WM_RBUTTONDOWN = 516; public static final int WM_RBUTTONUP = 517; public static final int WM_MBUTTONDOWN = 519; public static final int WM_MBUTTONUP = 520; public void dispose() { unsetMouseHook(); mousehook_thread = null; mouseHook = null; hhk = null; USER32INST = null; } public void unsetMouseHook() { isHooked = false; USER32INST.UnhookWindowsHookEx(hhk); System.out.println("Mouse hook is unset."); } public boolean isIsHooked() { return isHooked; } public void globalClickEvent(GlobalMouseClick m) { System.out.println(m); } private Thread mousehook_thread; public void setMouseHook() { mousehook_thread = new Thread(new Runnable() { @Override public void run() { try { if (!isHooked) { hhk = USER32INST.SetWindowsHookEx(14, mouseHook, Kernel32.INSTANCE.GetModuleHandle(null), 0); isHooked = true; System.out .println("Mouse hook is set.

  • How to start AJAX in Zend?

    - by Awan
    I am working on some projects as a developer(PHP,MySQL) in which AJAX and jQuery is already implemented. But now I want to learn implementation of AJAX and jQuery stuff. Can anyone tell me the exact steps with explanation? I have created a project in Zend. There is only one controller(IndexController) and two actions(a and b) in my project now. Now I want to use ajax in my project. But I don't know how to start. I read some tutorial but unable to completely understand. I have index.phtml like this: <a href='index/a'>Load info A</a> <br/> <a href='index/b'>Load info B</a> <br /> <div id=one>load first here<div> <div id=two>load second here</div> Here index is controller in links. a and b are actions. now I have four files like this: a1.phtml I am a1 a2.phtml I am a2 b1.phtml I am b1 b2.phtml I am b2 I think you have got my point. When user clicks first link (Load info A) then a1.phtml should be loaded into div one and a2.phtml should be loaded into div two When user clicks second link (Load info B) then b1.phtml should be loaded into div one and b2.phtml should be loaded into div two And someone tell me the purpose of JSON in this process and how to use this also? Thanks

  • Python unittest (using SQLAlchemy) does not write/update database?

I can even see the SQL statements from SQLAlchemy and step through the newly created user object's email -- ...INFO sqlalchemy.engine.base.Engine.0x...954c INSERT INTO users (user_id, user_name, email, ...) VALUES (%(user_id)s, %(user_name)s, %(email)s, ...) ...INFO sqlalchemy.engine.base.Engine.0x...954c {'user_id': u'4cfdafe3f46544e1b4ad0c7fccdbe24a', 'email': u'[email protected]', ...} > .../tests/unit_tests/test_signup.py(127)test_signup_success() -> user = user_q.filter_by(user_name='test').first() (Pdb) n ...INFO sqlalchemy.engine.base.Engine.0x...954c SELECT users.user_id AS users_user_id, ... FROM users WHERE users.user_name = %(user_name_1)s LIMIT 1 OFFSET 0 ...INFO sqlalchemy.engine.base.Engine.0x...954c {'user_name_1': 'test'} > .../tests/unit_tests/test_signup.py(128)test_signup_success() -> self.assertTrue(isinstance(user, model.User)) (Pdb) user <pweb.models.User object at 0x9c95b0c> (Pdb) user.email u'[email protected]' Yet at the same time when I login to the test database, I do not see the new record there. Is it some feature from Python/unittest/SQLAlchemy/Pyramid/PostgreSQL that I'm totally unaware of? Thanks. Jerry

  • How to parse phpDoc style comment block with php?

    - by Reveller
    Please consider the following code with which I'm trying to parse only the first phpDoc style comment (noy using any other libraries) in a file (file contents put in $data variable for testing purposes): $data = " /** * @file A lot of info about this file * Could even continue on the next line * @author [email protected] * @version 2010-05-01 * @todo do stuff... */ /** * Comment bij functie bar() * @param Array met dingen */ function bar($baz) { echo $baz; } "; $data = trim(preg_replace('/\r?\n *\* */', ' ', $data)); preg_match_all('/@([a-z]+)\s+(.*?)\s*(?=$|@[a-z]+\s)/s', $data, $matches); $info = array_combine($matches[1], $matches[2]); print_r($info) This almose works, except for the fact that everything after @todo (including the bar() comment block and code) is considered the value of @todo: Array ( [file] => A lot of info about this file Could even continue on the next line [author] => [email protected] [version] => 2010-05-01 [todo] => do stuff... / /** Comment bij functie bar() [param] => Array met dingen / function bar() { echo ; } ) How does my code need to be altered so that only the first comment block is being parsed (in other words: parsing should stop after the first "*/" encountered?

  • Lack of security in many PHP applications?

    - by John
    Over the past year of freelancing, I inherited two web projects, both of them built in PHP, both of them with sensitive information like credit card info, bank info, etc... In one application, when I typed http://thecompany.com/admin/, and without being asked for a username and password, I saw every user's sensitive information, including credit card numbers, bank account numbers etc... In another application, I was able to bypass the login screen by simply typing http://the2ndcompany.com/customer.php?user_id=777, and again, without any prompts for username and password, i was able to see user 777's credit card info. I cycled through a few more user_ids (any integer) and saw each person's credit card info. Is something wrong here? Or is this the quality of work that the "average" programmer produces? Because if this is what the average programmer produces, does that means I'm an...gasp...elite programmer?? No..that can't be right....something doesn't make sense. So my question is, is it just coincidence that I inherited two applications both of which are dangerously lacking in security? Or are there are a lot of bad PHP programmers out there?

  • How to systematically generate images from data?

    - by adamvickers
    I work for a performing arts nonprofit. We have seating charts for each of the theaters we work with; each seating chart shows the number of sections, the shape of each section, and the number of rows in each section. We'd like to create dynamic seating charts based on this info. We'd like them to look/feel kinda like this: http://www.fansnap.com/tickets/177754-on. But the tricky part is we'd like to be able to store all the info about each theater (the section names, shape/size of each section, and number of rows in each section) as data and then build a system that reads this data and uses it to create a dynamic map. I'm a life-long web developer, but I don't have have any experience with a difficult graphics problem like this. I realize it's a complex problem and I don't expect anyone to give me a complete answer here, but I would love direction on where I should be looking for more info. Is what I'm describing possible? Does this sort of technique have a name? Where can I learn more about how to accomplish this? What software should I use? Any info would be helpful.

  • MS Exam 70-536 - How to throw and handle exception from thread?

    - by Max Gontar
    Hello! In MS Exam 70-536 .Net Foundation, Chapter 7 "Threading" in Lesson 1 Creating Threads there is a text: Be aware that because the WorkWithParameter method takes an object, Thread.Start could be called with any object instead of the string it expects. Being careful in choosing your starting method for a thread to deal with unknown types is crucial to good threading code. Instead of blindly casting the method parameter into our string, it is a better practice to test the type of the object, as shown in the following example: ' VB Dim info As String = o as String If info Is Nothing Then Throw InvalidProgramException("Parameter for thread must be a string") End If // C# string info = o as string; if (info == null) { throw InvalidProgramException("Parameter for thread must be a string"); } So, I've tried this but exception is not handled properly (no console exception entry, program is terminated), what is wrong with my code (below)? class Program { static void Main(string[] args) { Thread thread = new Thread(SomeWork); try { thread.Start(null); thread.Join(); } catch (InvalidProgramException ex) { Console.WriteLine(ex.Message); } finally { Console.ReadKey(); } } private static void SomeWork(Object o) { String value = (String)o; if (value == null) { throw new InvalidProgramException("Parameter for "+ "thread must be a string"); } } } Thanks for your time!

  • Query distinct list of choices for Django form with App Engine Datastore

    - by Brian
    I've been trying to figure this out for hours across a couple of days, and can not get it to work. I've been everywhere. I'll continue trying to figure it out, but was hoping for a quicker solution. I'm using App Engine datastore + Django. Using a query in a view and custom forms, I was able to get a list to the form but then I was not able to post. I have been trying to figure out how to dynamically add the choices as part of the Django form... I've tried various ways with no success. Help! Below are the two models. I'd like to get a distinct list of address_id to show in the location field in InfoForm. This fields could (and maybe should) be named the same, but I thought it'd be easier if they were named different. class Info(db.Model): user = db.UserProperty() location = db.StringProperty() info = db.StringProperty() created = db.DateTimeProperty(auto_now_add=True) modified = db.DateTimeProperty(auto_now=True) class Locations(db.Model): user = db.UserProperty() address_id = db.StringProperty() address = db.StringProperty() class InfoForm(djangoforms.ModelForm): info = forms.ChoiceField(choices=INFO_CHOICES) location = forms.ChoiceField() class Meta: model = Info exclude = ['user','created','modified']

  • How do I configure encodings (UTF-8) for code executed by Quartz scheduled Jobs in Spring framework

    - by Martin
    I wonder how to configure Quartz scheduled job threads to reflect proper encoding. Code which otherwise executes fine within Springframework injection loaded webapps (java) will get encoding issues when run in threads scheduled by quartz. Is there anyone who can help me out? All source is compiled using maven2 with source and file encodings configured as UTF-8. In the quartz threads any string will have encoding errors if outside ISO 8859-1 characters: Example config <bean name="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass" value="example.ExampleJob" /> </bean> <bean id="jobTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="jobDetail" /> <property name="startDelay" value="1000" /> <property name="repeatCount" value="0" /> <property name="repeatInterval" value="1" /> </bean> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="jobTrigger"/> </list> </property> </bean> Example implementation public class ExampleJob extends QuartzJobBean { private Log log = LogFactory.getLog(ExampleJob.class); protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException { log.info("ÅÄÖ"); log.info(Charset.defaultCharset()); } } Example output 2010-05-20 17:04:38,285 1342 INFO [QuartzScheduler_Worker-9] ExampleJob - vÖvÑvñ 2010-05-20 17:04:38,286 1343 INFO [QuartzScheduler_Worker-9] ExampleJob - UTF-8 The same lines of code executed within spring injected beans referenced by servlets in the web-container will output proper encoding. What is it that make Quartz threads encoding dependent?

  • Cannot serialize this List<T> extension

    - by Jaxidian
    I'm trying to push a subset of a collection of data through WCF to be consumed by WCF - think paged data. As such, I want this collection to have one page's worth of data as well as a total number of results. I figured this should be trivial by creating a custom object that extends List. However, everything I do results in my TotalNumber property coming across as 0. All of the data gets serialized/deserialized just fine but that single integer won't come across at all. Here's my first attempt that failed: [Serializable] public class PartialList<T> : List<T> { public PartialList() { } public PartialList(IEnumerable<T> collection) : base(collection) { } [DataMember] public int UnpartialTotalCount { get; set; } And here's my second attempt that failed in the exact same way: [Serializable] public class PartialList<T> : List<T>, ISerializable { public PartialList() { } public PartialList(IEnumerable<T> collection) : base(collection) { } [DataMember] public int UnpartialTotalCount { get; set; } protected PartialList(SerializationInfo info, StreamingContext context) { UnpartialTotalCount = info.GetInt32("UnpartialTotalCount"); } public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("UnpartialTotalCount", UnpartialTotalCount); } } What's the deal here??
