  • echoing javascript when an ajax funtion is called

    - by Roland
    I'm doing a ajax call via the normal jquery ajax funtion My ajax looks as follows jQuery('#yt10').live('click',function(){jQuery.ajax({'data':{'set':$("#booking_set_id1").val(),'setStat':$("#booking_stockStatus").val(),'setNum':$("#booking_setNum").val()},'beforeSend':function(){ if($("#booking_set_id1").val() == "" || $("#booking_stockStatus").val() == "" || $("#booking_setNum").val() == ""){ $("#error").addClass("flash-error"); $("#error").html("Please fill in all relevant set details before adding a set"); return false; } },'dataType':'html','success':function(data,status){ $("#mainrow").show(); $("#error").removeClass("flash-error"); $("#error").html(""); $("#setTable tr:last").after(data); $("#booking_set_id1").val(""); $("#booking_stockStatus").val(""); $("#booking_setNum").val(""); },'url':'/booking/newSet','cache':false});return false;}); Now the function newSet needs to echo javascript to the bowser but somehow jquery filters the javscript out. Is it possible to echo javascript via ajax

  • Get Taskbar's Battery and PhoneSignal indicators icons and draw into a picturebox (C#/WindowsMobile)

    - by Christian Almeida
    Hi, Is there any way to get taskbar's battery and phonesignal indicators icons and then draw into a picturebox or something? Why do I need this? I need all screen space available, so all forms are maximized and they cover up the windowsmobile taskbar. But, I have to display information about battery e phone signal strength in just a couple of forms. I know how to get their values (like systeminformation.phonesignalstrength), but what I want is the "current icon", so I don't need to worry about their values. It's just a visual information for the user. In last case, if this is not possible, how to get those icons from windowsmobile shell, so I'll draw them by my self, treating each differente status/values that they assume. (This is what I don't want to do!) Thanks in advance and sorry for my poor english.

  • Can't get websrvmng to run in Plesk SSH terminal.

    - by JohnB
    I am following this MediaTemple KB article and stuck at the last step. When I try to run the websrvmng (using the ssh terminal in Plesk) using the code the KB references: /usr/local/psa/admin/sbin/websrvmng -v -a I receive a 'File or Directory not found' error. I am a n00b when it comes to this stuff and would really appreciate any advice/suggestions for how to get websrvmng to run. I have searched through tons of articles on it but found nothing more illuminating than the above code. I am sure I'm overlooking something simple (login as root to run? something I need to replace in the code like usr?). It is a MediaTemple DV server running CentOS 5 and as I said using Plesk. I desperately need to get this to work and I am pulling my hair out, so as I said any help would be greatly appreciated.

  • Geopraphic Charting controls for Websites

    - by Ian
    Hi All, I need to create dash boards showing geographic regions and show sales, hot spots etc on a map. What have you tried and what do you recommend? I like the look of both Fusion Charts and Dundas I will be using asp.net for the site but any control's or library's including flash or javascript are good options. Most important is the look and feel followed by functionality in South Africa. After my last post looking for commercial mapping solutions, it looks like they are very expensive and now I am investigating alternatives to full mapping solutions. thanks

  • Java TCP keep-alive for a master server

    - by asmo
    Context: Master server (Java, TCP) monitoring a list of hosted games (a different machine for the master server and for each hosted game server). Any user can host a game on his PC. Hosted games can last weeks or months. Need: Knowing when hosted game servers are closed or no longer reachable. Restriction 1: Can't rely on hosted servers' "gone offline update message", since those messages may never arrive (power down, Internet link cut, etc.) Restriction 2: I'm not sure about TCP's built-in keep-alive, since it would mean a 24/7 open socket with each hosted server (correct me if I'm wrong) Any thoughts?

  • Python: unix socket -> broken pipe

    - by Heinrich Schmetterling
    I'm trying to get Python socket working as an alternative to calling the command line socat. This socat command works fine: echo 'cmd' | sudo socat stdio <path-to-socket> but when I run this python code, I get an error: >>> import socket >>> s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM) >>> s.connect(<path-to-socket>) >>> s.send('cmd') Traceback (most recent call last): File "<stdin>", line 1, in <module> socket.error: (32, 'Broken pipe') Any ideas what the issue is? Thanks.

  • Optimizing if-else /switch-case with string options

    - by cc
    What modification would bring to this piece of code? In the last lines, should I use more if-else structures, instead of "if-if-if" if (action.equals("opt1")) { //something } else { if (action.equals("opt2")) { //something } else { if ((action.equals("opt3")) || (action.equals("opt4"))) { //something } if (action.equals("opt5")) { //something } if (action.equals("opt6")) { //something } } } Later Edit: This is Java. I don't think that switch-case structure will work with Strings. Later Edit 2: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ).

  • What is the best software to capture full-screen 3h programming session in Windows?

    - by Hugo S Ferreira
    Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

  • Idiomatic ruby for temporary variables within a method

    - by Andrew Grimm
    Within a method, I am using i and j as temporary variables while calculating other variables. What is an idiomatic way of getting rid of i and j once they are no longer needed? Should I use blocks for this purpose? i = positions.first while nucleotide_at_position(i-1) == nucleotide_at_position(i) raise "Assumption violated" if i == 1 i -= 1 end first_nucleotide_position = i j = positions.last while nucleotide_at_position(j+1) == nucleotide_at_position(j) raise "Assumption violated" if j == sequence.length j += 1 end last_nucleotide_position = j Background: I'd like to get rid of i and j once they are no longer needed so that they aren't used by any other code in the method. Gives my code less opportunity to be wrong. I don't know the name of the concept - is it "encapsulation"? The closest concepts I can think of are (warning: links to TV Tropes - do not visit while working) Chekhov'sGun or YouHaveOutlivedYourUsefulness. Another alternative would be to put the code into their own methods, but that may detract from readability.

  • Handling button click in ASP.NET MVC 2 RTM

    - by Leniel Macaferi
    I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request.

  • Time to ignore IDisposable?

    - by Mystagogue
    Certainly we should call Dipose() on IDisposable objects as soon as we don't need them (which is often merely the scope of a "using" statement). If we don't take that precaution then bad things, from subtle to show-stopping, might happen. But what about "the last moment" before process termination? If your IDisposables have not been explicitly disposed by that point in time, isn't it true that it no longer matters? I ask because unmanaged resources, beneath the CLR, are represented by kernel objects - and the win32 process termination will free all unmanaged resources / kernel objects anyway. Said differently, no resources will remain "leaked" after the process terminates (regardless if Dispose() was called on lingering IDisposables). Can anyone think of a case where process termination would still leave a leaked resource, simply because Dispose() was not explicitly called on one or more IDisposables? Please do not misunderstand this question: I am not trying to justify ignoring IDisposables. The question is just technical-theoretical.

  • Jquery click() not behaving like user click

    - by rpiontek
    I have searched for a solution to this for the last several hours but to no avail. When I click on a button that has a return false in OnClientClick, no postback occurs to the server. When I use jquery to trigger the click function of the button, OnClientClick fires first, but regardless of the return value, a postback occurs. Here's a simple sample... So, in this example, when Button1 is clicked normally, no postback occurs. When Button2 is clicked, a postback always occurs. Is this a bug or intended behavior?

  • How can I set partial text color in JTextArea

    - by ComputerJy
    I want to set color for specific lines in the text area. What I've found so far, was the following // Declarations private final DefaultStyledDocument document; private final MutableAttributeSet homeAttributeSet; private final MutableAttributeSet awayAttributeSet; // Usage in the form constructor jTextAreaLog.setDocument(document); homeAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(homeAttributeSet, Color.blue); StyleConstants.setItalic(homeAttributeSet, true); awayAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(awayAttributeSet, Color.red); // Setting the style of the last line final int start = jTextAreaLog.getLineStartOffset(jTextAreaLog.getLineCount() - 2); final int length = jTextAreaLog.getLineEndOffset(jTextAreaLog.getLineCount() - 1) - start; document.setCharacterAttributes(start, length, awayAttributeSet, true); But this is not working. What am I doing wrong?

  • Reusing Object does not work properly

    - by balexandre
    Hi guys, I'm reusing a created Object just to change a Date and the ordinal value, but at the end I get 6 objects exactly as the last. in other words, I'm adding the object as a Reference and I should add as a Value What should I inherit my Object to have the Copy() method ? RecurringPayment rp, copy; rp = new RecurringPayment { ... } payments.Add(rp); // add first object copy = rp; // Copy the original element for (int i = 1; i <= 5; i++) { copy.NextPaymentDate = copy.NextPaymentDate.AddDays(copy.RecurringTime * 7); copy.OrderOrdinal = copy.OrderOrdinal + 1; payments.Add(copy); // add 5 more with X weeks ahead } Thank you

  • Setting outbound 'Expires:' in Squid server's HTTP header

    - by IkeaPimp
    I'm having a problem where items served by my Squid server are being cached by Limelight for too long, sometimes days. It happens when a piece of content has been static for a long time (weeks) and then undergoes numerous changes in a matter of hours. Limelight gets its content from our Squid server and I'm told that if I can add 'Expires: 15m' in the HTTP header the Squid server sends, Limelight will not cache the image for more than 15 min. Unfortunately, I can fond no setting in Squid that will allow me to add this to the header. Here's the HTTP header as presently being sent: HTTP/1.0 200 OK Date: Tue, 15 Dec 2009 23:57:33 GMT Server: nginx/0.5.26 Content-Type: image/jpeg Content-Length: 83843 Last-Modified: Tue, 15 Dec 2009 23:52:00 GMT Accept-Ranges: bytes Age: 450 X-Cache: HIT from squid01.prod.mydomain X-Cache-Lookup: HIT from squid01.prod.mydomain:3128 Via: 1.0 squid01.prod.mydomain:3128 (squid/2.6.STABLE14) Connection: close

Being trying to solve this for a few days now. Thanks!

  • Calculate total by javascript in gridview with paging

    - by louis
    Without paging function, i can loop through the gridview by using var sum = 0; var gridViewCtlId = '<%=timesheetView.ClientID%>'; var grid = document.getElementById(gridViewCtlId); var gridLength = grid.rows.length; so with gridLength i can loop through the gridview to sum all rows. However, when I use paging event of gridview, i use the page size to loop through all rows, but it occurs errors because the last page may not have enough rows. So would you please to help me how to get the rows in the each page of gridview?

  • MemSet & MemCopy

    - by pws5068
    I'm writing a memory allocator, and I need a way to store an integer inside of a chunk of memory. This integer will represent the size of the block so I can navigate to the end given the pointer to the beginning. Here's my test example: head_ptr = (char*) malloc(4*1024*1024); // Allocate 4MB memset(head_ptr,12345,sizeof(int)); // Set Address head_ptr = 12345 memcpy(testInt,head_ptr,sizeof(int)); // Set testInt = head_ptr printf("testInt = %i",testInt); This throws a segmentation fault on the second to last line. Does what I'm trying to do make sense? If so, what is the correct approach?

  • Building iPhone static library for armv6 and armv7 that includes another static library

    - by Martijn Thé
    Hi, I have an Xcode project that has a "master" static library target, that includes/links to a bunch of other static libraries from other Xcode projects. When building the master library target for "Optimized (armv6 armv7)", an error occurs in the last phase, during the CreateUniversalBinary step. For each .o file of the libraries that is included by the master library, the following error is reported (for example, the FBConnectGlobal.o file): warning for architecture: armv6 same member name (FBConnectGlobal.o) in output file used for input files: /Developer_Beta/Builds/MTToolbox/MTToolbox.build/Debug-iphoneos/MTToolbox.build/Objects-normal/armv6/libMTToolbox.a(FBConnectGlobal.o) and: /Developer_Beta/Builds/MTToolbox/MTToolbox.build/Debug-iphoneos/MTToolbox.build/Objects-normal/armv7/libMTToolbox.a(FBConnectGlobal.o) due to use of basename, truncation and blank padding In the end, Xcode tells that the build has succeeded. However, when using the final static library in an application project, it won't build because it finds duplicate symbols in one part of build (armv6) and misses symbols in the other part of the build (armv7). Any ideas how to fix this? M

  • Tomcat gzip while chunked issue

    - by hoodoos
    I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Content-Encoding: gzip Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recieved, but then after ungzipping I see that response is partial. I never seen such behavior with gzip turned off in request headers. So my question is: is it common tomcat issue? maybe one of it's mod which is doing compression? Or maybe it maybe some kind of proxy issue? I can't tell about versions of tomcat or what gzip mod they use, but feel free to ask, i'll try ask my service provider. Thanks.
