  • Is there a way to create a string that matches a given C# regex?

    - by Chris Phillips
    My application has a feature that parses text using a regular expression to extract special values. I find myself also needing to create strings that follow the same format. Is there a way to use the already defined regular expression to create those strings? For example, assume my regex looks something like this: public static Regex MyRegex = new Regex( @"sometext_(?<group1>\d*)" ); I'd like to be able to use MyRegex to create a new string, something like: var created = MyRegex.ToString( new Dictionary<string, string>() {{ "group1", "data1" }}; Such that created would then have the value "sometextdata1".

  • Checking for multiple images loaded

    - by Stanni
    Hi, I'm using the canvas feature of html5. I've got some images to draw on the canvas and I need to check that they have all loaded before I can use them. I have declared them inside an array, I need a way of checking if they have all loaded at the same time but I am not sure how to do this. Here is my code: var color = new Array(); color[0] = new Image(); color[0].src = "green.png"; color[1] = new Image(); color[1].src = "blue.png"; Currently to check if the images have loaded, I would have to do it one by one like so: color[0].onload = function(){ //code here } color[1].onload = function(){ //code here } If I had a lot more images, Which I will later in in development, This would be a really inefficient way of checking them all. How would I check them all at the same time?

  • Why people define class, trait, object inside another object in Scala?

    - by Zwcat
    Ok, I'll explain why I ask this question. I begin to read Lift 2.2 source code these days. In Lift, I found that, define inner class and inner trait are very heavily used. object Menu has 2 inner traits and 4 inner classes. object Loc has 18 inner classes, 5 inner traits, 7 inner objects. There're tons of codes write like this. I wanna to know why the author write it like this. Is it because it's the author's personal taste or a powerful use of language feature?

  • Shared memory of same DLL in different 32 bit processes is sometimes different in a terminal session

    - by KBrusing
    We have an 32 bit application consisting of some processes. They communicate with shared memory of a DLL used by every process. Shared memory is build with global variables in C++ by "#pragma data_seg ("Shared")". When running this application sometime during starting a new process in addition to an existing (first) process we observe that the shared memory of both processes is not the same. All new started processes cannot communicate with the first process. After stopping all of our processes and restarting the application (with some processes) everything works fine. But sometime or other after successfully starting and finishing new processes the problem occurs again. Running on all other Windows versions or terminal sessions on Windows server 2003 our application never got this problem. Is there any new "feature" on Windows server 2008 that might disturb the hamony of our application?

  • Enableeventvalidation in web user control

    - by Khushi
    Hi, i have a web user control containing a repeater. The repeater contains three buttons. On button click it gives the following error : Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. Since user control does not have page directive, so i changed the enableEventValidation to false, but it restricted the itemcommand event of the repeater. Can someone guide me, how to solve this problem?

  • Can the LibreOffice LightProof grammar library be used externally?

    - by Phyxx
    LibreOffice 3.5 includes a grammar checker, called (or maybe based on) LightProof. From what I have read, LightProof seems to be a Python library that can be used to check for custom grammar rules. But I can not for the life of me find a project page for LightProof. The closest I got was http://cgit.freedesktop.org/libreoffice/lightproof/tree/, which seems to be the code for the LibreOffice extension, not LightProof itself. So is LightProof actually a library that can be implemented in other applications, or is it just a code word for a LibreOffice feature?

  • Visual Studio scratch disk behavior

    - by bobobobo
    I don't know if this feature exists, but I'd like a way to control Visual Studio 2010's scratch disk behavior (other than completely turning off intellisense). Right now it creates a massive .sdf file in the project folder (50MB+), and then it goes and creates an IPCH folder with 60MB+ of precompiled headers. All that's well and good while VS is running, but after it exits, I really would like the disk back. Is there a way to configure vs 2010 to Use the same location (%AppData%\VSScratch) for scratch disk files (so its easier to blow it away?) Automatically delete .sdf /ipch on exit? I know they don't delete them because its faster to startup.. but if you delete them yourself, startup time isn't that much increased..

  • How can I get Facebook Profile image from email?

    - by Forbini
    There's an outlook plugin called Xobni that has a really cool feature, if a contact has an email address, it will fetch that contact's profile picture and display it. Their FAQ states the following: Xobni sends an encrypted email address to Facebook to retrieve the Facebook profile for the person who is currently being viewed in the Xobni sidebar. Your own Facebook profile is never altered by Xobni, and all Facebook privacy settings are strictly followed when viewing other profiles. I'd like to duplicate this functionality. However, I can't figure out which API call they're using. I'm assuming when they say "encrypted email address" that's laymen's terms for the email hash. Once a username is derived, the graph api looks ideal for actually fetching the image, but I'm having trouble going from email hash to profile ID.

  • database search function on an HTML page possible?

    - by synergy989
    Not sure if this is against stackoverflow rules as it's not a specific code question but I really need a little help. I want to know if it is possible to create a search feature (search box) on an HTML webpage that will query a database and return the results? Basically I have a database of products and their related categories. A user would come to the website, enter the category in the search field...somehow query the database and return the results on a new page. Note: the results page doesn't have to be HTML (could be PHP etc). If you could also include a little guidance on how (please nothing detailed, just need a direction). Thank you!

  • how to call functions/methods within CMS block or page?

    - by latvian
    Hi, We are trying to make all our blocks and pages static so that designer or anyone else can easily change the content or design of the website, however. There is a feature that uses our own custom module. So, the template that we want to make static is calling methods out of our custom block, for example, <!--some html code--> ..... <?php $this->helpMeBePartOfCMS(); ?> ..... <!--some html code--> How do i incorporate these method calls inside cms block or page? Thank you

  • Model association changes in production environment, specifically converting a model to polymorphic?

    - by dustmoo
    Hi everyone, I was hoping I could get feedback on major changes to how a model works in an app that is in production already. In my case I have a model Record, that has_many PhoneNumbers. Currently it is a typical has_many belongs_to association with a record having many PhoneNumbers. Of course, I now have a feature of adding temporary, user generated records and these records will have PhoneNumbers too. I 'could' just add the user_record_id to the PhoneNumber model, but wouldn't it be better for this to be a polymorphic association? And if so, if you change how a model associates, how in the heck would I update the production database without breaking everything? .< Anyway, just looking for best practices in a situation like this. Thanks!

  • SQL: Optimize insensive SELECTs on DateTime fields

    - by Fedyashev Nikita
    I have an application for scheduling certain events. And all these events must be reviewed after each scheduled time. So basically we have 3 tables: items(id, name) scheduled_items(id, item_id, execute_at - datetime) - item_id column has an index option. reviewed_items(id, item_id, created_at - datetime) - item_id column has an index option. So core function of the application is "give me any items(which are not yet reviewed) for the actual moment". How can I optimize this solution for speed(because it is very core business feature and not micro optimization)? I suppose that adding index to the datetime fields doesn't make any sense because the cardinality or uniqueness on that fields are very high and index won't give any(?) speed-up. Is it correct? What would you recommend? Should I try no-SQL? -- mysql -V 5.075 I use caching where it makes sence.

  • Have anyone ever create/manipulate a table application from the ground up/scratch?

    - by Darwin
    Have anyone ever create/manipulate a table application from the ground up/scratch? I want to create a table using flash AS 3. I like to have the features like to the MS Studio Web Developer option. The options are create a table, merge cells, split cell, resize columns, delete cell, delete row, delete column etc... I think this is going to be very complicated thing to do. I think the only way to do it is to build it from the ground up because I don’t think Flash has the library/component for it. I was able to create rows and columns by creating the # of rectangles listed it from the left to the right and move the next coordinate for the next row. Now the most challenging this is to manipulate it. This is the must have feature on my website and we don’t want use Javascript to create table on the server side to create the table.

  • Length of text that can just fit into one screen without scrolling

    - by KailZhang
    I find some iphone book apps have such feature: One screen one page of text without scrolling. The text can just fit into the whole screen with linebreaks and indentations. I'm curious of how to implement this. How could I decide the length of text that just fit into the screen. And also, given the whole text, I can calculate out the number of pages. If this is not possible to be done on iPhone(runtime?), then is it possible to process the text before storing it in app? I mean I calculate how many pages I need(how to split the raw text), probably how many lines per page.

  • Initialise a wix CheckBox's check state based on a property?

    - by MauriceL
    How does one initalise a Wix check box based on the value of a property? So far, I've done the following: <Control Id="Checkbox" Type="CheckBox" X="0" Y="0" Width="100" Height="15" Property="CHECKBOX_SELECTION" Text="I want this feature" CheckBoxValue="1" TabSkip="no"> <Condition Action="hide">HIDE_CHECKBOX</Condition> <Condition Action="show">NOT HIDE_CHECKBOX</Condition> </Control> Currently I have two custom actions to set HIDE_CHECKBOX and CHECKBOX_SELECTION. The CHECKBOX_SELECTION custom action occurs immediately after the HIDE_CHECKBOX action. What I'm seeing is that HIDE_CHECKBOX is behaving correctly (ie. the checkbox is hidden) which suggests that I've got the ordering of custom actions correct, but CHECKBOX_SELECTION is not changing the check state of the check box. Is this a safe assumption? Also, I've confirmed that SELECTION is being set to '1' in the logs.

  • Secure method for linking to image files uploaded via custom CMS

    - by letseatfood
    How does one provide a direct URL for an image file (JPEG) that is secure? For example, if a PHP script writes uploaded images to directory http://www.somehost.com/images, is it okay to provide http://www.somehost.com/images/someimage.jpg as the URL, or is there a more secure way to do this? Should I look into something like the permalink feature that is a part of Wordpress? I am not sure if that is related. The main reason I ask is that I have a custom PHP/MySQL CMS for managing images. I would like for the client to be able to copy a link to the image they want and then include it in a TinyMCE text editor for inserting the image in their website. Thanks!

  • Is there a tool that automatically saves incremental changes to files while coding?

    - by Bob.
    One of my favorite features of Google docs is the fact that it's constantly automatically saving versions of my document as I work. This means that even if I forget to save at a certain point before making a critical change there's a good chance that a save point has been created automatically. At the very least, I can return the document to a state prior to the mistaken change and continue working from that point. Is there a tool with an equivalent feature for a Ruby coder running on Mac OS (or UNIX)? For example, a tool that will do an automatic Git check-in every couple of minutes to my local repository for the files I'm working on. Maybe I'm paranoid, but this small bit of insurance could put my mind at ease during my day-to-day work.

  • Is object clearing/array deallocation really necessary in VB6/VBA (Pros/Cons?)

    - by Oorang
    Hello, A lot of what I have learned about VB I learned from using Static Code Analysis (Particularly Aivosto's Project Analyzer). And one one of things it checks for is whether or not you cleared all objects and arrays. I used to just do this blindly because PA said so. But now that I know a little bit more about the way VB releases resources, it seems to me that these things should be happening automatically. Is this a legacy feature from pre VB6, or is there a reason why you should explicitly set objects back to nothing and use Erase on arrays?

  • Mercurial: two separate repos somewhat related (yes I'm getting confused)

    - by Lo'oris
    I have a local repository, let's call it ONE. ONE is the actual program. It's an android program, in case it matters for some reason. I have a remote repository, let's call it EXT. EXT is somewhat a library, used by ONE. ONE has a complex directory structure, mandated by android. The main sources are in src/bla/bla/ONE. Since ONE uses EXT, to do it I had to create another directory next to that one, that is src/bla/bla/EXT. I think would like to keep them separated in two repositories, but I need for them to actually be in this same directory structure to compile ONE. At the moment I just created a symlink to do it, but I wonder if there is a better way of doing that, that uses some hg feature.

  • Extracting friends' E-Mail addresses from Facebook (Skype?)

    - by chephy
    I am currently in the process of migrating away from Facebook (privacy concerns, mostly). For obvious reasons, I want to save away the email addresses from my friends' profile pages. However, this turned out to be a rather hard task, because the Facebook API doesn't let you access any mail addresses. However, I just tried the automatic contact import feature of Skype, and it seems to be able to retrieve the email addresses of my friends from Facebook. Does anyone know how it's done so I could replicate it?

  • [PyQt4] QFileDialog problem (native: fast but no input field; non-native: has input field but slow)

    - by Bing Jian
    Hi, This seems a known problem but I have not found a good workaround. I like the style of the non-native QFileDialog, especially the feature that allows the user to input the path directly which is very convenient since the user can easily copy/paste the folder/file name from other applications. However, it seems very slow when the dialog is first launched. The native option is quite responsive but the problem is that it does not provide an input field so for the user to select a folder he/she has to walk into the directory, which can take many mouse clicks and is not fun. I am not sure if you have experienced similar problem or if I miss something. BTW, my PyQt version is 4.4.3 and I am working on Windows XP. Thanks, Bing

  • Unexpected output on initializing array by using both `element-by-element` & `designated` technique

    - by haccks
    C99 provides a feature to initialize arrays by using both element-by-element & designated method together as: int a[] = {2,1,[3] = 5,[5] = 9,6,[8] = 4}; On running the code: #include <stdio.h> int main() { int a[] = {2,1,[3] = 5,[0] = 9,4,[6] = 25}; for(int i = 0; i < sizeof(a)/sizeof(a[0]); i++) printf("%d ",a[i]); return 0; } (Note that Element 0 is initialized to 2 and then again initialised by designator [0] to 9) I was expecting that element 0(which is 2) will be replaced by 9(as designator [0] = 9) and hence o/p will become 9 1 0 5 4 0 25 Unfortunately I was wrong as o/p came; 9 4 0 5 0 0 25 Any explanation for unexpected o/p?
