  • using multi-markers with multi info-windows

    - by mohsen
    I have an array of info-windows corresponding to an array of markers. Now, I have a problem, I use the below code to generate an info-window, when clicking on the marker all the markers disappear unless one, also when I click on that marker there is no info-window come out. What is the wrong with my code ? or what shall I do ? Any answer will be very appreciated, Thanks in advance. This code is inside a for loop: infoWindoArray[i][j] = new google.maps.InfoWindow({ content:"Lat: "+this.position.lat() + "\nLng: " + this.position.lng() + "\n"+ this.customInfo, }); google.maps.event.addListener(AllMarkers[i][j], 'click', (function(x) { return function() {infoWindoArray[i][j].open(map,AllMarkers[i][j]);} })(x));

  • How do I close a form when the ESC key was hit, but only if no Control handled it?

    - by Gabriel
    I have a Form that closes itself when the ESC key is pressed, thanks to KeyPreview, ProcessKeyEventArgs, ProcessCmdKey or whatever. But I have a Control on that form that does very relevant things when ESC is pressed (it hides itself) and the Form should not be closed when that happens. The control uses the KeyDown event and sets the SuppressKeyPress flag to true, but that happens after the aforementioned form key preview, thus having no effect. Is there some sort KeyPostview ? How do I not close the form when a Control has a relevant use of a key hit ? Edit: The control handling ESC is a textbox embedded in a hand-maid ListView. The textbox appears when the user clicks a cell, enabling edition. To validate the new text, ENTER would be nice (that already works, as giving the focus to anything else). To cancel edition, ESC seems most natural.

  • jquery live() method on custom functions

    - by user271619
    I have a custom event handler, or I suppose some call it a custom jquery function. My problem is I'm trying to apply the live() method to it. But I'm not too successful. Here's a simple custom jquery function: $.fn.myFunction = function() { return $(this).addClass('changed'); } And here I use it: $('.changePlease').myFunction(); Ok, simple enough. But how do I apply the live() method to it?? I actually have no idea if that's even possible. But I do use live() for other things, like: $(".changePlease").live("click",function(){ alert("hello"); }); Any thoughts on this?

  • How to create a glib.Source from Python?

    - by Matt Joiner
    I want to integrate some asyncore.dispatcher instances into GLib's default main context. I figure I can create a custom GSource that's able to detect event readiness on the various sockets in asyncore.socket_map. From C I believe this is done by creating the necessary GSourceFuncs which could involve cheap and non-blocking calls to select, and then handling them using asyncore.read, .write and friends. How do I actually create a GSource from Python? The class glib.Source is undocumented, and attempts to use the class interactively have been in vain. Is there some other method that allows me to handled socket events in the asyncore module without resorting to timeouts (or anything that endangers potential throughput and CPU usage)?

  • Why do my WPF UIElements NOT have OnPreview events?

    - by Matt.M
    I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

  • API For Flex Apps To Interact

    - by dimo414
    I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

  • VBA form_error vs on error

    - by dmr
    I am trying to set up error handling for a MS-Access application. The standard method to do this seems to be with an On Error statement in each subroutine/function. It seems simpler to me to use the Form_Error function to catch all the runtime errors in that form as opposed to an On Error statement for each sub/function called by an event on that form. (Obviously, for code in modules, there is no Form_Error function and therefore the only method is the On Error statement) What are the pros and cons of using On Error vs Form_Error?

  • Java/Swing: Problem with key listener

    - by Mike
    I have a search dialog with a JTextField that's being used as a search box. When the user types something, it searches the DB, shows the result in a JTable and selects the first item in it. If the first result is what they were looking for, I want to let them quickly accept the dialog, by pressing Enter (while the JTextField is focused). So I added a KeyListener to the JTextField and it's working OK. Now the problem: The user opens can open the dialog by pressing Enter when a "Search" button on the dialog's parent frame is focused. The dialog is displayed and the JTextField gets the keyReleased event (from the Enter key that displayed it), so it shows up and closes. If the user holds Enter down, then the JTextField receives the keyPressed, keyTyped and keyReleased events. How can I fix without resorting to ugly workarounds? Platform is Windows 7 x64, btw. Test NetBeans project here: http://dl.dropbox.com/u/6354360/KeyListenerTest.zip Thanks.

  • passing paramters to component in flex

    - by dubbeat
    Hi, I've got 2 files, my Application and a custom component. In my component I have a httpservice and a string named _requestUrl that is bindable. The httpservice uses this. <mx:HTTPService id="srv" url="{_requestUrl}" result="parseHttpResult(event)" resultFormat="xml" method="GET" useProxy="false"> </mx:HTTPService> In my application file I make an instance of my component in the onCreationComplete function. In this function if I say mycomponent._urlRequest ="http://mysite.com" the httpservice throws a null url error but if I say mycomponent.srv.url="http://mysite.com" it works fine. Why is this?

  • assistance with fxcop

    - by amateur
    I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

  • Callback for When jqGrid Finishes Reloading?

    - by James
    Hi, I am using the jqGrid plug-in and at one point I need to refresh the grid and set the selected row to match the record that I am showing in detail on another section of the page. I have the following code but it does not work: $("#AllActions").trigger("reloadGrid").setSelection(selectedRow); The selectedRow parameter comes from an event handler that gets called when the data is changed and the grid needs to be updated. I'm pretty sure that the problem is that the grid is not loaded when the selection is being set, because if I put a call to alert() between the calls to trigger() and setSelection(), it works. I would be grateful for any advice. [Edit]Looks like http://stackoverflow.com/questions/2529581/jqgrids-setselect-does-not-work-after-reloadgrid is related but did not get resolved.[/Edit]

  • Application disappears after starting - C++ linking managed code dll

    - by Axarydax
    Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP3 x86, and all applications linking managed code dll do not work. After starting the .exe seemingly nothing happens, no window pops up, no memory gets eaten, no task shows in task manager, nothing, nada. Event log is empty, everything is just as if the application returned to the OS right after the start. I am at loss about this, I really don't know how should I start even debugging this problem. I don't want to install VS2010 and everything onto a Windows XP box, I'd like to try something less time intensive first. This all is happening just to native C++ apps that link managed c++ DLL. Pure managed C# apps do work. Pure native C++ apps do work.

    I have the following code which is working, I was wondering if this can simplified more.

Jquery was used to check and uncheck them. Regards

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code. You may modify mine. This code works (javascript) with much smoother frame rate and max bandwidth usage. but the later code (java) dont. same 3 to 8 seconds gap. <!DOCTYPE html> <html> <head> <script type="text/javascript"> (function(){ var img="/*url*/"; var interval=50; var pointer=0; function showImg(image,idx) { if(idx<=pointer) return; document.body.replaceChild(image,document.getElementsByTagName("img")[0]); pointer=idx; preload(); } function preload() { var cache=null,idx=0;; for(var i=0;i<5;i++) { idx=Date.now()+interval*(i+1); cache=new Image(); cache.onload=(function(ele,idx){return function(){showImg(ele,idx);};})(cache,idx); cache.src=img+"?"+idx; } } window.onload=function(){ document.getElementsByTagName("img")[0].onload=preload; document.getElementsByTagName("img")[0].src="/*initial url*/"; }; })(); </script> </head> <body> <img /> </body> </html> and of java (with problem) : package camba; import java.applet.Applet; import java.awt.Button; import java.awt.Graphics; import java.awt.Image; import java.awt.Label; import java.awt.Panel; import java.awt.TextField; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.URL; import java.security.Timestamp; import java.util.Date; import java.util.concurrent.TimeUnit; import java.util.concurrent.atomic.AtomicBoolean; import javax.imageio.ImageIO; public class Camba extends Applet implements ActionListener{ Image img; TextField textField; Label label; Button start,stop; boolean terminate = false; long viewTime; public void init(){ label = new Label("please enter camera URL "); add(label); textField = new TextField(30); add(textField); start = new Button("Start"); add(start); start.addActionListener(this); stop = new Button("Stop"); add(stop); stop.addActionListener(this); } public void actionPerformed(ActionEvent e){ Button source = (Button)e.getSource(); if(source.getLabel() == "Start"){ for (int i = 0; i < 7; i++) { myThread(50*i); } System.out.println("start..."); } if(source.getLabel() == "Stop"){ terminate = true; System.out.println("stop..."); } } public void paint(Graphics g) { update(g); } public void update(Graphics g){ try{ viewTime = System.currentTimeMillis(); g.drawImage(img, 100, 100, this); } catch(Exception e) { e.printStackTrace(); } } public void myThread(final int sleepTime){ new Thread(new Runnable() { public void run() { while(!terminate){ try { TimeUnit.MILLISECONDS.sleep(sleepTime); } catch (InterruptedException ex) { ex.printStackTrace(); } long requestTime= 0; Image tempImage = null; try { URL pic = null; requestTime= System.currentTimeMillis(); pic = new URL(getDocumentBase(), textField.getText()); tempImage = ImageIO.read(pic); } catch(Exception e) { e.printStackTrace(); } if(requestTime >= /*last view time*/viewTime){ img = tempImage; Camba.this.repaint(); } } }}).start(); System.out.println("thread started..."); } }

  • How can I unit test an Android Activity that acts on Accelerometer?

    - by Corey Sunwold
    I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

  • Cant get Tomcat6.0 to work with Windows 7 Environment

    - by CitadelCSCadet
    Prior to upgrading to windows 7, I was able to use Tomcat 6.0, but when I upgraded to the new Windows, and downloaded Eclipse EE, and downloaded the apache content, I am unable to get Apache to run. When I attempt to start my apacher server through either system tray, or even windows services, it gives the followign error screen. "Windows could not start the Apache Tomcat 6 on local computer. For more information review the system event log. Refer to server specific error code 0." I have been able to locate some forums about error code 0, and some other documentation on this problem, but none of the solutions seems to work. One of the solutions I came across said to take the msvcr71.dll (mscvrt.dll on new platforms) and put it into the bin folder of apache. This also did not work. Does anybody know a fix for this problem, or a way to get around it so I can get my server up and running thanks.
