  • What could the negative effects be of attaching to a process as a debugger?

    - by I_like_traffic_lights
    Background A client of mine has a major problem. They have a CRM system, which was created by a single person over a period of 9 years. Unfortunatelly, a few weeks ago, this person died. I believe the company has learned their lesson, and they have started a project of rewriting the CRM system to a modern platform. I have been hired to create a solution in the meantime to make adaptations to the CRM system. I have given up understanding the code, as this would take too long. My solution, is therefore, to make a window and show this on top of the CRM system, whenever this CRM system is showing. This part works fine, but my major problem is extracting the data from the CRM system. Proposed solution After excluding 6 approaches, including runtime code injection, memory searching, database integration, I have arrived at attaching to the process as a debugger, so I get notified about event, and use this in combination with reading from process memory. This approach seems to work, but I am worried about possible side-effects of this approach. Question What are the dangers of using this in a production environment, where there are 250 employees utilizing the system. Needless to say, I cannot risk reducing the already shaky stability of the system.

  • Issues with simple jQuery image gallery with Colorbox plugin

    - by Chris
    I'm putting together an image gallery for an ecommerce site and wanting to use colorbox to launch larger images. My problem is that image launched in colorbox stays as the first one launched and should reflect the image shown as img#bigpic - the link to the image does appear to be updating correctly. Here's the jQuery I have: $(document).ready(function(){ $("#largeimage").colorbox(); imageSwapper(".thumbnails a"); function imageSwapper(link) { $(link).click(function(){ $("#bigpic").attr("src", this.href); $("#largeimage").attr("href", this.rel); return false; }); }; $("#largeimage").bind('mouseenter mouseleave', function(event) { $("#largeimage span").toggleClass('showspan'); }); }); ...and the HTML <a href="_images/products/large/bpn0001_1.jpg" id="largeimage"><span></span><img src="_images/products/bpn0001_1.jpg" id="bigpic" /></a> <div class="thumbnails"> <ul> <li><a href="_images/products/bpn0001_1.jpg" rel="_images/products/large/bpn0001_1.jpg"><img src="_images/products/mini/bpn0001_1.jpg" /></a></li> <li><a href="_images/products/bpn0001_2.jpg" rel="_images/products/large/bpn0001_2.jpg"><img src="_images/products/mini/bpn0001_2.jpg" /></a></li> <li><a href="_images/products/bpn0001_3.jpg" rel="_images/products/large/bpn0001_3.jpg"><img src="_images/products/mini/bpn0001_3.jpg" /></a></li> </ul> </div> Any help would be much appreciated!

  • How do I unbind another jQuery function on .click()?

    - by Mike Barwick
    I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

  • What is the fastest (to access) struct-like object in Python?

    - by DNS
    I'm optimizing some code whose main bottleneck is running through and accessing a very large list of struct-like objects. Currently I'm using namedtuples, for readability. But some quick benchmarking using 'timeit' shows that this is really the wrong way to go where performance is a factor: Named tuple with a, b, c: >>> timeit("z = a.c", "from __main__ import a") 0.38655471766332994 Class using __slots__, with a, b, c: >>> timeit("z = b.c", "from __main__ import b") 0.14527461047146062 Dictionary with keys a, b, c: >>> timeit("z = c['c']", "from __main__ import c") 0.11588272541098377 Tuple with three values, using a constant key: >>> timeit("z = d[2]", "from __main__ import d") 0.11106188992948773 List with three values, using a constant key: >>> timeit("z = e[2]", "from __main__ import e") 0.086038238242508669 Tuple with three values, using a local key: >>> timeit("z = d[key]", "from __main__ import d, key") 0.11187358437882722 List with three values, using a local key: >>> timeit("z = e[key]", "from __main__ import e, key") 0.088604143037173344 First of all, is there anything about these little timeit tests that would render them invalid? I ran each several times, to make sure no random system event had thrown them off, and the results were almost identical. It would appear that dictionaries offer the best balance between performance and readability, with classes coming in second. This is unfortunate, since, for my purposes, I also need the object to be sequence-like; hence my choice of namedtuple. Lists are substantially faster, but constant keys are unmaintainable; I'd have to create a bunch of index-constants, i.e. KEY_1 = 1, KEY_2 = 2, etc. which is also not ideal. Am I stuck with these choices, or is there an alternative that I've missed?

  • (closed) nodejs responding an image (via pipe and response.end()) leads into strange behaviour

    - by johannesboyne
    What the Problem was: I had 2 different writeStreams! If WriteStram#1 is closed, the second should be closed too and then it all should be piped... BUT node is asynchronious so while one has been closed, the other one hasn't. Even the stream.end() was called... well you always should wait for the close event! thx guys for your help! I am at my wit's end. I used this code to pipe an image to my clients: req.pipe(fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res)) it does work but sometimes the image is not transferred completely. But no error is thrown neither on client side (browser) nor on server side (node.js). My second try was var img = fs.readFileSync(__dirname+'/imgen/cached_images/' + link); res.writeHead(200, { 'Content-Type' : 'image/png' }); res.end(img, 'binary'); but it leads to the same strange behaviour... Does anyone got a clue for me? Regards! (abstracted code...) var http = require('http'); http.createServer(function (req, res) { Imgen.generateNew( 'virtualtwins/www_leonardocampus_de/overview/28', 'www.leonardocampus.de', 'overview', '28', null, [], [], function (link) { fs.stat(__dirname+'/imgen/cached_images/' + link, function(err, file_info) { if (err) { console.log('err', err); } console.log('file info', file_info.size); res.writeHead(200, 'image/png'); fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res); }); } ); }).listen(13337, '127.0.0.1'); Imgen.generateNew just creates a new file, saves it to the disk and gives back the path (link)

  • Why does the BackgroundWorker in WPF need Thread.Sleep to update UI controls?

  • ASP.NET DropDownList control doesn't postback correctly inside of UserControl

    - by RichardAZ
    I have a situation where a DropDownList control is not posting back correctly. The AutoPost property is set to true, so the postback does happen, but the SelectedValue is not set to the correct value. In addition, the onSelectedIndexChanged event doesn't fire. The exact same code works perfect fine on an ASPX page, but does not work in a ASCX control. I have tried all the obvious things, I hope, trying to figure this one out, but no luck so far. I have even investigated what comes back in Request.Form["__EVENTTARGET"] and __EVENTARGUMENT. __EVENTTARGET does point to the drop down list, but the argument is empty. Can the folks of StackOverflow help lead me in the right direction to debug this issue. Of course, it is further complicated by master pages and the usual overcomplication of ASP.NET. Here is the code: <div> <asp:DropDownList ID="testDrop" runat="server" AutoPostBack="true" EnableViewState="true" onselectedindexchanged="testDrop_SelectedIndexChanged"> <asp:ListItem Value="1" Text="1">1</asp:ListItem> <asp:ListItem Value="2" Text="2">2</asp:ListItem> </asp:DropDownList> </div> And here is the generated html: <select id="ctl00_MainContent_rptAccordion_ctl00_statControl_testDrop" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop\',\'\')', 0)" name="ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop"> <option value="1" selected="selected">1</option> <option value="2">2</option> THANKS!

  • How do I change the application background color at run-time in a Flex 3.5 application?

    - by Adam Tuttle
    I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

  • Dynamic Views based on view models

    - by Joe
    I have an asp.net mvc 2 app. I need to display the same page to each user. But each user has different rights to the data. IE some can see but not edit some data, some cannot edit nor see the data. Ideally data that cannot be seen nor edited is whitespace on the view. For security reasons I want my viewmodels to be sparse as possible. By that I mean if a field cannot be seen nor edited , that field should not be on the viewmodel. Obviously I can write view for each view model but that seems wasteful. So here is my idea/wishlist Can I decorate the viewmodel with attributes and hook into a pre render event of the html helpers and tell it to do &nbsp; instead??? Can I have the html helpers output &nbsp; for entries not found on the viewmodel?? or can I easily convert a view built into code then programaticlly build the markup and then put into the render engine to be processed and viewd as html on client side??

  • Reload a UITable on the fly when editing a UITextField inside one of the cells

    - by Saze
    I have a UITable containing some customs UITableCells. Those cells contain a few UILabels and a UITextField. The datasource of the table comes from a main controller's property. (This controller is also the delegate and the dataSource for the table). Here's a simplified screenshot of the UI: Now, I need to update "on the fly" the content of all the UILabels when the user edits one of the UITextFields. To do so, at the I am listening to the "Editing Changed" event at the UITextField level. This triggers the following action: - (IBAction) editChangeHandler: (id) sender { MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [[delegate.viewController.myDataSourceArray objectAtIndex:self.rowIndex] setANumber: [theTextField.text intValue]]; [delegate.viewController reloadRows]; } The reloadRows method in the viewController is as such: - (void) reloadRows { NSLog(@"called reloadRows"); //perform some calculations on the data source objects here... [theUITable reloadData]; } My problem here is that whenever the user changes the value in the field, the reloadRows method is successfully called, so is apparently the reloadData but it also causes the keyboard to be dismissed. So in the end, the user can only touch one key when editing the TextField before the keyboard is dismissed and the table reloaded. Does anybody knows a solution to this or have experienced the same issue?

  • Stopping a SoundPlayer loop at the local level

    - by EvanRyan
    I'm working on setting up an alarm that pops up as a dialog with multiple sound file options the user can choose from. The problem I'm having is creating a sound player at the local level that I can close with a button. The problem I'm having is that the sound keeps looping when I close the form because the SoundPlayer doesn't exist within the button click event. here's what I have: void callsound() { if (SoundToggle == 0) // if sound enabled { if ((SoundFile == 0) && (File.Exists(@"attention.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"attention.wav"); alarm.PlayLooping(); } if ((SoundFile == 1) && (File.Exists(@"aahh.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"aahh.wav"); alarm.PlayLooping(); } } private void button1_Click(object sender, EventArgs e) { //alarm.Stop(); Only works if SoundPlayer declared at class level this.Close(); } Is there a way I can do what I want to do by declaring the SoundPlayer instances where I am? Or is there a way to declare it at the class level, and still be able to change the sound file based on user settings?

    - by Industrial
    Hi everybody, We have a web server that we're about to launch a number of applications on. On the server-level we have managed to work out the error handling with the help of Hyperic to notify the person who is in charge in the event of a database/memcached server is going down. However, we are still in the need of handling those eventual error and log events that happen on application level to improve the applications for our customers, before the customers notices. So, what's then a good solution to do this? Utilizing PHP:s own error log would quickly become cloggered if we would run a big number of applications at the same time. It's probably isn't the best option if you like structure. One idea is to build a off-site lightweight error-handling application that has a REST/JSON API that receives encrypted and serialized arrays of error messages and stores them into a database. Maybe it could, depending on the severity of the error also be directly inputted into our bug tracker. Could be a few well spent hours, but it seems like a quite fragile solution and I am sure that there's better more-reliable alternatives out there already. Thanks,

  • DateChooser is behaving strangely

    - by Tam
    I'm writing a Flex application and I came across what I think is a weird problem. I want to create a text box and a DateChooser as the datefield didn't do what I wanted and it's Halo so I can't skin it easily. I want the DateChooser to show when I click on the text input. Here is an except from my code: <s:TextInput id="wholeDate" width="100" mouseOver="stopChangeToNormal();" paddingRight="10" click="date1.visible = true" focusOut="date1.visible = false"/> <s:Button label="Go" width="70" /> </s:Panel> <mx:DateChooser id="date1" visible = "false" change="useDate(event);" mouseOver="changeToNormalState = false;" y="{wholeDate.y + buttonsGroup.y + 20}" x="{wholeDate.x + buttonsGroup.x - 175 }" /> The weird thing is that it works as I wanted if I make it visible = "true" to start but if I have it visible="false" it doesn't work! It shows but the date I select doesn't show in the box as it does if I have it as visible="true", but I don't want it to be visible initially. Any ideas?

  • Sheet and thread memory problem

    - by Xident
    Hi Guys, recently I started a project which can export some precalculated Grafix/Audio to files, for after processing. All I was doing is to put a new Window (with progressindicator and an Abort Button) in my main xib and opened it using the following code: [NSApp beginSheet: REC_Sheet modalForWindow: MOTHER_WINDOW modalDelegate: self didEndSelector: nil contextInfo: nil]; NSModalSession session=[NSApp beginModalSessionForWindow:REC_Sheet]; RECISNOTDONE=YES; while (RECISNOTDONE) { if ([NSApp runModalSession:session]!=NSRunContinuesResponse) break; usleep(100); } [NSApp endModalSession:session]; A Background Thread (pthread) was started earlier, to actually perform the work and save all the targas/wave file. Which worked great, but after an amount of time, it turned out that the main thread was not responding anymore and my memory footprint raised unstoppable. I tried to debug it with Instruments, and saw a lot of CFHash etc stuff growing to infinity. By accident i clicked below the sheet, and temporary it helped, the main thread (AppKit ?) was releasing it's stuff, but just for a little time. I can't explain it to me, first of all I thought it was the access from my thread to the Progressbar to update the Progress (intervalled at 0,5sec), so I cut it out. But even if I'm not updating anything and did nothing with the Progressbar, my Application eat up all the Memory, because of not releasing it's "Main-Event" or whatsoever Stuff. Is there any possibility to "drain" this Main thread Memory stuff (Runloop / NSApp call?). And why the heck doesn't the Main thread respond anymore (after this simple task) ??? I don't have a clou anymore, please help ! Thanks in advance ! P.S. How do you guys implement "threaded long task" Stuff and updating your gui ???

  • include ::before pseudo class in javascript

    - by user1955837
    Why is this thing not working? If I remove ::before from javascript and css it works. But due to the design needs there has to be a ::before. How do I point to the class + ::before? $(function () { var sections = $("section"); var navigation_links = $("nav a"); sections.waypoint({ handler: function (event, direction) { var active_section; active_section = $(this); if (direction === "up") active_section = active_section.prev(); var active_link = $('nav a[href="#' + active_section.attr("id") + '"]'); navigation_links.removeClass("selected::before"); active_link.addClass("selected::before"); }, offset: '25%' }) }); css: .selected::before { display: block; content: ""; margin-top: 6px; width: 8px; height: 8px; background: url(../img/sprite.png) -126px -196px; background-size: 400px 480px; float: left; margin-left: 20px; margin-right: 20px; }

  • Efficient batch SQL query execution on Android, for upgrade database.

    - by Pentium10
    As we Android developers know, the SQLiteDatabase execSQL method can execute only one statement. The doc says: Execute a single SQL statement that is not a query. For example, CREATE TABLE, DELETE, INSERT, etc. Multiple statements separated by ;s are not supported. I have to load in a batch of records, 1000 and counting. How do I insert these efficiently? And what's the easiest way to deliver these SQLs with your apk? I mention, there is already a system database and I will run this on the onUpdate event. I have this code so far: List<String[]> li = new ArrayList<String[]>(); li.add(new String[] { "-1", "Stop", "0" }); li.add(new String[] { "0", "Start", "0" }); /* the rest of the assign */ try { for (String[] elem : li) { getDb().execSQL( "INSERT INTO " + TABLENAME + " (" + _ID + "," + NAME + "," + PARSE_ORDER + ") VALUES (?,?,?)", elem); } } catch (Exception e) { e.printStackTrace(); }
