  • IronPython memory leak?

    - by Mike Gates
    Run this: for i in range(1000000000): a = [] It looks like the list objects being created never get marked for garbage collection. From a memory profiler, it looks like the interpreter's stack frame is holding onto all the list objects, so GC can never do anything about it. Is this by design?

  • how to shift windows forms controls?

    - by Mike
    How can i get same functionality in windows forms as in the next example. When i have two links one beneath, and when i click first link a panel is visibleunder it and next link is shifted. When i click again the panel is invisible and second link shifted back. <script type="text/javascript"> function toggleDivState(divName) { var ctl = window.document.getElementById(divName); if (ctl.style.display == "none") ctl.style.display = ""; else ctl.style.display = "none"; } </script> <a href="javascript:toggleDivState('poll<%# Eval("ID") %>');"> <div style="display: none;" id="poll<%# Eval("ID") %>">

  • XML to JSON - losing root node

    - by Mike
    I'm using net.sf.json with a Java project and it works great. The conversion of this XML: <?xml version="1.0" encoding="UTF-8"?> <important-data certified="true" processed="true"> <timestamp>232423423423</timestamp> <authors> <author> <firstName>Tim</firstName> <lastName>Leary</lastName> </author> </authors> <title>Flashbacks</title> <shippingWeight>1.4 pounds</shippingWeight> <isbn>978-0874778700</isbn> </important-data> converts to this in JSON: { "@certified": "true", "@processed": "true", "timestamp": "232423423423", "authors": [ { "firstName": "Tim", "lastName": "Leary" }], "title": "Flashbacks", "shippingWeight": "1.4 pounds", "isbn": "978-0874778700" } However, the root tag <important-data> is lost in the conversion. Being new to XML and JSON, I am not sure if this is suppose to be the correct behaviour. If not, is there any way to tell net.sf.json to convert it while keeping the root node property? Thanks.

  • Same source, multiple targets with different resources (Visual Studio .Net 2008)

    - by Mike Bell
    A set of software products differ only by their resource strings, binary resources, and by the strings / graphics / product keys used by their Visual Studio Setup projects. What is the best way to create, organize, and maintain them? i.e. All the products essentially consist of the same core functionality customized by graphics, strings, and other resource data to form each product. Imagine you are creating a set of products like "Excel for Bankers", Excel for Gardeners", "Excel for CEOs", etc. Each product has the the same functionality, but differs in name, graphics, help files, included templates etc. The environment in which these are being built is: vanilla Windows.Forms / Visual Studio 2008 / C# / .Net. The ideal solution would be easy to maintain. e.g. If I introduce a new string / new resource projects I haven't added the resource to should fail at compile time, not run time. (And subsequent localization of the products should also be feasible). Hopefully I've missed the blindingly-obvious and easy way of doing all this. What is it? ============ Clarification(s) ================ By "product" I mean the package of software that gets installed by the installer and sold to the end user. Currently I have one solution, consisting of multiple projects, (including a Setup project), which builds a set of assemblies and create a single installer. What I need to produce are multiple products/installers, all with similar functionality, which are built from the same set of assemblies but differ in the set of resources used by one of the assemblies. What's the best way of doing this? ------------ The 95% Solution ----------------- Based upon Daminen_the_unbeliever's answer, a resource file per configuration can be achieved as follows: Create a class library project ("Satellite"). Delete the default .cs file and add a folder ("Default") Create a resource file in the folder "MyResources" Properties - set CustomToolNamespace to something appropriate (e.g. "XXX") Make sure the access modifier for the resources is "Public". Add the resources. Edit the source code. Refer to the resources in your code as XXX.MyResources.ResourceName) Create Configurations for each product variant ("ConfigN") For each product variant, create a folder ("VariantN") Copy and Paste the MyResources file into each VariantN folder Unload the "Satellite" project, and edit the .csproj file For each "VariantN/MyResources" <Compile> or <EmbeddedResource> tag, add a Condition="'$(Configuration)' == 'ConfigN'" attribute. Save, Reload the .csproj, and you're done... This creates a per-configuration resource file, which can (presumably) be further localized. Compile error messages are produced for any configuration that where a a resource is missing. The resource files can be localized using the standard method (create a second resources file (MyResources.fr.resx) and edit .csproj as before). The reason this is a 95% solution is that resources used to initialize forms (e.g. Form Titles, button texts) can't be easily handled in the same manner - the easiest approach seems to be to overwrite these with values from the satellite assembly.

  • jquery ui autcomplete does not disapper with no result

    - by mike
    Hi, I'm using jquery ui autocomplete with the following code: $('#company').autocomplete({ source: function(request, response) { var company_name = $('#company').val(); $.ajax({ type: 'post', url: 'http://new.admin.localhost/client/helper/lookup_company_name', cache: false, data: { company : company_name }, dataType: 'json', success: function(data) { //alert(data); response($.map(data.companies, function(item) { return { label: item.company, value: item.company } })) } }) }, minLength: 2, }); This works as expected... The problem is, if the first few chars match something and then you enter a char that should "break" any match, it just keeps the drop down in place with the results for the last matched char... make sense? Would this be something I needed to change in the script that returns the data or something in the jquery? thanks!

  • Problems getting PowerPoint Combobox to list items correctly

    - by mike toyn
    I am creating a PowerPoint in which I want users to be able to select an item from a list in a combo box. Nothing needs to happen after this, it is just to provide a record, on screen, of their choice. My problem is that I seem to either be able to populate the combo box and users can select an item but the list gets longer each time the combobox is clicked on (i.e each time it is clicked on the list gets duplicated). Or alternatively, I can clear the combo box, then populate it but in this scenario, the users choice also seems to get cleared. VBA example 1: Private Sub ComboBox1_DropButtonClick() With ComboBox1 .AddItem " ", 0 .AddItem "speed", 1 .AddItem "provisionality", 2 .AddItem "automation", 3 .AddItem "replication", 4 .AddItem "communicability", 5 .AddItem "multi-modality", 6 .AddItem "non-linearity", 7 .AddItem "capacity", 8 .AddItem "interactivity", 9 End With End Sub VBA example 2: Private Sub ComboBox1_DropButtonClick() ComboBox1.Clear With ComboBox1 .AddItem " ", 0 .AddItem "speed", 1 .AddItem "provisionality", 2 .AddItem "automation", 3 .AddItem "replication", 4 .AddItem "communicability", 5 .AddItem "multi-modality", 6 .AddItem "non-linearity", 7 .AddItem "capacity", 8 .AddItem "interactivity", 9 End With End Sub Can anyone help?

  • Comparison question string vs int

    - by Mike
    Can someone explain to me why these comparisons work they way the do. I had a bug in one of my scripts that took me a little bit to work through. I was using read-host and typing a number. It was storing it as a string. Write-Host "(`'2`' -gt 9 ) = " ('2' -gt 9 ) Write-Host "(2 -gt 9 ) = " (2 -gt 9 ) Write-Host "(`'2`' -gt 10 ) = " ('2' -gt 10 ) If you are comparing a string to an Int does it use the Ascii value? If so why does the first one show $false, it should be $true. Then how is it when you chage it to an int of 10 it because $true.

  • iPad web app: Prevent input focus AFTER ajax call

    - by Mike Barwick
    So I've read around and can't for the life of me figure out of to solve my issue effectively. In short, I have a web app built for the iPad - which works as it should. However, I have an Ajax form which also submits as it should. But, after the callback and I clear/reset my form, the "iPad" automatically focuses on an input and opens the keyboard again. This is far from ideal. I managed to hack my way around it, but it's still not perfect. The code below is run on my ajax callback, which works - except there's still a flash of the keyboard quickly opening and closing. Note, my code won't work unless I use setTimeout. Also, from my understanding, document.activeElement.blur(); only works when there's a click event, so I triggered one via js. IN OTHER WORDS, HOW DO I PREVENT THE KEYBOARD FROM REOPENING AFTER AJAX CALL ON WEB APP? PS: Ajax call works fine and doesn't open the keyboard in Safari on the iPad, just web app mode. Here's my code: hideKeyboard: function () { // iOS web app only, iPad IS_IPAD = navigator.userAgent.match(/iPad/i) != null; if (IS_IPAD) { $(window).one('click', function () { document.activeElement.blur(); }); setTimeout(function () { $(window).trigger('click'); }, 500); } } Maybe it's related to how I'm clearing my forms, so here's that code. Note, all inputs have tabindex="-1" as well. clearForm: function () { // text, textarea, etc $('#campaign-form-wrap > form')[0].reset(); // checkboxes $('input[type="checkbox"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.checkbox').removeClass('checked'); // radio inputs $('input[type="radio"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.radio').removeClass('checked'); // selects $('form.custom .user-generated-field select').each(function () { var selection = $(this).find('option:first').text(), labelFor = $(this).attr('name'), label = $('[for="' + labelFor + '"]'); label.find('.selection-choice').html(selection); }); optin.hideKeyboard(); }

  • Google Maps API v3.9: Blurry custom markers when zooming

    - by Mike
    So it appears that Google have fixed the blurry map issue with the 3.9 / 3.10 API, which is great. But there's a new one with custom markers. As soon as you zoom in one level, the custom markers become corrupted / blurry. They rectify themselves if zooming out, although the process of zooming out also makes the markers slightly blurry. The 3.8 API does not exhibit this problem with custom markers. Here's a picture illustrating the problem (I suggest you open the image in a new tab; the blurriness isn't as easily visible when the image is scaled to fit this post). The blurring is most noticeable with the straight lines of the paper crane marker: I've had a prod through the HTML, but I can't really tell how the markers are placed on the map. But I thought that I'd put this issue out there for anyone who has experienced similar, or if anyone has any thoughts on how this can be resolved, save waiting to see if it's a glitch in the API.

  • Should constant contructor aguments be passed by reference or value?

    - by Mike
    When const values are passed to an object construct should they be passed by reference or value? If you pass by value and the arguments are immediately fed to initializes are two copies being made? Is this something that the compiler will automatically take care of. I have noticed that all textbook examples of constructors and intitializers pass by value but this seems inefficient to me. class Point { public: int x; int y; Point(const int _x, const int _y) : x(_x), y(_y) {} }; int main() { const int a = 1, b = 2; Point p(a,b); Point q(3,5); cout << p.x << "," << p.y << endl; cout << q.x << "," << q.y << endl; } vs. class Point { public: int x; int y; Point(const int& _x, const int& _y) : x(_x), y(_y) {} }; Both compile and do the same thing but which is correct?

  • How should I generate HTML to represent class and its properties?

    - by Mike
    Currently I have a class that represents a document. This document needs to be displayed as HTML. I would like to have a method to call such as GetHTML() that would then call GetHTML() on any properties/sections of the document that needed to be rendered. I was initially thinking about using linq and XElement but am wondering if that may cause issues with certain tags in HTML. Would I better off using an HtmlTextWriter? I am open to any suggestions or best practives for this situation. Thanks!

  • Detect at runtime which country's App Store my iPhone app was downloaded from?

    - by Mike McMaster
    I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

  • Batch convert Malformed PDFs to TIF on Linux

    - by Mike Driscoll
    I need to convert a multipage PDF to TIF, but it appears to be a malformed PDF provided by our client. I tried using ImageMagick and GhostScript, but they do not convert the file correctly. The result is only about 85-90% correct. The only thing I've found that appears to do the job is GIMP, but I can't find an example to use it via its Batch Processing methods for PDFs. Here are the warnings I get from ImageMagick and GhostScript: **** Warning: Tf refers to an unknown resource name: FORMS$.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: P06BOB.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: P06BOB.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: P06BOB.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN307A.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN104A.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: HE14BP.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN106E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN106E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: HE08BP.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: HE11BP.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: AR10NP.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN308E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: JIMP2.l Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: HS11C.l Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: FORMS$.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN104A.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN208E.f Assuming it's a font name. **** Warning: Tf refers to an unknown resource name: UN307E.f Assuming it's a font name. **** This file had errors that were repaired or ignored. **** Please notify the author of the software that produced this **** file that it does not conform to Adobe's published PDF **** specification.

  • pass custom environment variables to System.Diagnostics.Process

    - by Mike Ruhlin
    I'm working on an app that invokes external processes like so: ProcessStartInfo startInfo = new ProcessStartInfo(PathToExecutable, Arguments){ ErrorDialog = false, RedirectStandardError = true, RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true, WorkingDirectory = WorkingDirectory }; using (Process process = new Process()) { process.StartInfo = startInfo; process.Start(); process.BeginErrorReadLine(); process.BeginOutputReadLine(); process.WaitForExit(); return process.ExitCode; } One of the processes I'm calling depends on an environment variable that I'd rather not require my users to set. Is there any way to modify the environment variables that get sent to the external process? Ideally I'd be able to make them visible only to the process that's running, but if I have to programmatically set them system-wide, I'll settle for that (but, would UAC force me to run as administrator to do that?) ProcessStartInfo.EnvironmentVariables is read only, so a lot of help that is...

  • Co-opt popular abandonware opensource project?

    - by Mike Bouck
    Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has set up a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In other words the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, set up a new community site, and take matters in their own hands?

  • JavaScript: Changing src-attribute of a embed-tag

    - by Mike
    I have the following scenario. I show the user some audio files from the server. The user clicks on one, then onFileSelected is eventually executed with both the selected folder and file. What the function does is change the source from the embedded object. So in a way, it is a preview of the selected file before accepting it and save the user's choice. A visual aid. HTML <embed src="/resources/audio/_webbook_0001/embed_test.mp3" type="audio/mpeg" id="audio_file"> JavaScript function onFileSelected(file, directory) { jQuery('embed#audio_file').attr('src', '/resources/audio/'+directory+'/'+file); }; Now, this works fine in Firefox, but Safari and Chrome simply refuse to change the source, regardless of Operating System. jQuery finds the object (jQuery.size() returns 1), it executes the code, but no change in the HTML Code. Why does Safari prevent me from changing the <embed> source and how can I circumvent this?

  • YUI Image Loader Images Above Fold Not Loading Until Scroll event.

    - by Mike
    I have a function that is called on the window.onload event to create a group of images and render via the scroll event. function LoadImages(){ var foldGroup = new YAHOO.util.ImageLoader.group(window, 'scroll'); for(var i=0; i<someCounter; i++){ var locationId = locationsArr[i]; foldGroup.registerSrcImage('Location_' + locationId, GetImageDomain()+'/templates/Includes/imagehandler.ashx?locationId=' + locationid); } foldGroup.foldConditional = true; foldGroup.addTrigger(window, 'resize'); } The problem I'm having is that when the page loads, the images "above the fold" are not rendered until I scroll. Is there any tips on troubleshooting this? I'm totally not a js/frontend guy :) Thanks in advance!
