  • How long does a MailItem.Property[myProperty] live?

    - by Darien Ford
    I'm writing a TransportAgent for Exchange and want to tag a MailItem with some identifying information. The MailItem class seems to have this functionality with the MailItem.Properties property; however, my question is to the length of time an entry would remain available. e.g. e.MailItem.Properties.Add(new KeyValuePair<string,object>("MyKey", "myValue")); After this MailItem is delivered to the correct mailbox, if someone were to reply to the email, would the newly created reply retain that set value? I think while writing this question out I have answered it for myself (which rationally would be no) but any practical experience and insight would be appreciated.

  • Get client timezone (not GMT offset amount) in JS

    - by Rex M
    I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

  • Where is the best place to put <script> tags in HTML markup?

    - by mipadi
    When embedding JavaScript in an HTML document, where is the best place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). This seems to leave the end of the <body> section as a logical place for <script> tags. So, where is the best place to put the <script> tags? (This question references this question, in which it was suggested that JavaScript function calls should be moved from <a> tags to <script> tags. I'm specifically using JQuery, but more general answers are also appropriate.)

  • An exception to the "only one implementation" rule ?

    - by ereOn
    While I was reading the accepted answer of this question, I had the following question: Typically, methods are defined in header files (.hpp or whatever), and implementation in source files (.cpp or whatever). One of the main reasons it is bad practice to ever include a "source file" (#include <source_file.cpp>) is that its methods implementation would then be duplicated, resulting in linking errors. When one writes: #ifndef BRITNEYSPEARS_HPP #define BRITNEYSPEARS_HPP class BritneySpears { public: BritneySpears() {}; // Here the constructor has implementation. }; #endif /* BRITNEYSPEARS_HPP */ He is giving the implementation of the constructor (here an "empty" implementation, but still). But why then including this header file multiple times (aka. on different source files) will not generate a "duplicate definition" error at link time ?

  • What's the "right" way to get Win32 p/Invoke declarations?

    - by Daniel Earwicker
    I typically use the site http://www.pinvoke.net/ to grab a DllImport declaration whenever I need to call a Win32 API, and I've noticed it's the de facto standard response on Stack Overflow to API interop questions. Is this what "everyone" does? Is there a better way? Does Microsoft offer an alternative? e.g. a tool that reads .h files and outputs an assembly. Why aren't there some standard assemblies that just expose all the Win32 APIs? What would be the barrier to creating them and using them, as an alternative to a site like pinvoke.net?

  • Facebook like box not working on mobile browser

    - by Kelend
    I'm writing a simple splash page for a client to hold a like box widget: <iframe src="http://www.facebook.com/plugins/likebox.php?id=***********&amp;width=238&amp;connections=4&amp;stream=false&amp;header=false&amp;height=200" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:238px; height:200px;" allowTransparency="true"></iframe> The page displays fine, with the like box, but when you click on the like it depresses without prompting the user to logon and does not update facebook. This behavior seems to be on mobile browsers only. On desktop browsers (ie8, firefox, safari) it works just fine. Anyone had this happen, and if so what was their solution?

  • The implicit function __strcpy_chk() call

    - by Summer_More_More_Tea
    Hi everyone: I'm now performing a stack buffer overflow attack test on my own PC( Ubuntu 9.10, gcc-4.4.1 ) based on the article http://www.tenouk.com/Bufferoverflowc/Bufferoverflow4.html. Yet I haven't achieved the goal. Each time a segfault is thrown accompanied with some error informaiton. I compile the source code, and wanna get further information using objdump. Function __strcpy_chk is invoked in the assembly code dumped out, and it's said that "The __strcpy_chk() function is not in the source standard; it is only in the binary standard." Does this the mechanism a compiler employed to protect runtime stack? To finish my test, how can I bypass the protection? Regards.

  • Windows Mobile 6.x How to explicitly lock the app in one orientation?

    - by Stuart
    I'm trying to get an app on the WinMo App Store. As part of this, Microsoft App's Store has asked that I need to support landscape as well as portrait. What they've said is OK is: If dynamic switching is implicitly allowed, the app will be tested just as if it supports both portrait and landscape even if only a portrait or landscape resolution is checked. You may explicitly lock the app in one orientation (which means portrait mode if the app does not handle landscape mode functions), provided the default OS orientation is preserved once the app exits. I'd love to do answer 2 - but I can't find any way of doing it - and they won't provide me any other clues - they suggested I ask on the forums... so here I am on Stack Overflow - far better than on the forums :) Anyone got any suggestions?

  • Do Managers in Python Multiprocessing module lock the shared data?

    - by AnonProcess
    This Question has been asked before: http://stackoverflow.com/questions/2936626/how-to-share-a-dictionary-between-multiple-processes-in-python-without-locking However I have several doubts regarding the program given in the answer: The issue is that the following step isn't atomic d['blah'] += 1 Even with locking the answer provided in that question would lead to random results. Since Process 1 read value of d['blah'] saves it on the stack increments it and again writes it. In Between a Process 2 can read the d['blah'] as well. Locking means that while d['blah'] is being written or read no other process can access it. Can someone clarify my doubts?

  • Initialising structs in C++

    - by Neil Butterworth
    As an addendum to this question, what is going on here: #include <string> using namespace std; struct A { string s; }; int main() { A a = {0}; } Obviously, you can't set a std::string to zero. Can someone provide an explanation (backed with references to the C++ Standard, please) about what is actually supposed to happen here? And then explain for example): int main() { A a = {42}; } Are either of these well-defined? Once again an embarrassing question for me - I always give my structs constructors, so the issue has never arisen before.

  • OO C++ - Virtual Methods

    - by Phorce
    Just a really quick question here. I'm using virtual functions to read in from a text file. Now, it's virtual because in one aspect I want the values to be normalised, and, in the other respect I don't want them to be normalised. I have tried to do this: bool readwav(string theFile, 'native'); So in theory, if the 'native' is used, this method should be called, however, if 'double' is called then a different version of the method is called. Same for if the value is empty, it should just perform the native option. First question, why doesn't the declaration above work? Also, is this the best route to go down? Or, would it be better to have just one class method that switches between the options. Thanks :)

  • How to find the number of inversions in an array ?

    - by Michael
    This is an phone interview question: "Find the number of inversions in an array". I guess they mean O(N*log N) solution since O(N^2) is trivial. I guess it cannot be better than O(N*log N) since sorting is O(N*log N) I have checked a similar question from SO and can summarize the answers as follows: Calculate half the distance the elements should be moved to sort the array : copy the array and sort the copy. For each element of the original array a[i] find it's position j in the sorted copy (binary search) and sum abs(i - j)/2. Modify merge sort : modify merge to count inversions between two sorted arrays (it takes O(N)) and run merge sort with the modified merge. Does it make sense ? Are there other (maybe simpler) solution ? Isn't it too hard for a phone interview ?

  • FACEBOOK LINTER ERROR: value for property 'og:image:url' could not be parsed as type 'url'

    - by Martin Devarda
    I've read all threads in stack overflow about this issue, but my problem persists. THE PROBLEM IS ON THIS PAGE: http://www.organirama.it/minisite-demo/001.html THE PAGE CONTAINS THIS TAGS <meta property="og:title" content="A wonderful page" /> <meta property="og:type" content="video.movie" /> <meta property="og:url" content="http://www.organirama.com/minisite-demo/001.html" /> <meta property="og:image" content="http:/www.organirama.com/minisite-demo/photos-small/001.png" /> <meta property="og:site_name" content="Organirama"/> <meta property="fb:admins" content="1468447924"/> LINTER ERROR Object at URL 'http://www.organirama.com/minisite-demo/001.html' of type 'video.movie' is invalid because the given value 'http:/www.organirama.com/minisite-demo/photos-small/001.png' for property 'og:image:url' could not be parsed as type 'url'. WHAT I DISCOVERED The problem seems somehow related to the domain. Infact, if I make og:image point to another image on another domain, everything works.

  • Can I add and remove elements of enumeration at runtime in Java

    - by Brabster
    It is possible to add and remove elements from an enum in Java at runtime? For example, could I read in the labels and constructor arguments of an enum from a file? @saua, it's just a question of whether it can be done out of interest really. I was hoping there'd be some neat way of altering the running bytecode, maybe using BCEL or something. I've also followed up with this question because I realised I wasn't totally sure when an enum should be used. I'm pretty convinced that the right answer would be to use a collection that ensured uniqueness instead of an enum if I want to be able to alter the contents safely at runtime.

  • How to remove hyperlink but keep text for an array of links?

    - by Keith Donegan
    My question is fairly similar to this question: Remove hyperlink but keep text? but, I can't seem to workout how I can feed an array of class names and do this in one go? For Example <a class="unwrap" href="#">Blah</a> <a class="unwrap" href="#">Blah</a> <a href="#">Blah</a> <a class="unwrap" href="#">Blah</a> I would just like the links with the unwrap class to be modified.

  • is it possible to use a python scrapper in a website?

    - by Tom
    I want to scrap a website and use that content in a website of my own. I am just wondering if that can be done with python 2.7, and if so how? If not, do I have to use JavaScript to scrap it? And do you have a good place to learn how to do that or good libraries for it. For those of you wondering, the website I am scrapping is legal, and they allow for this to be done. I have searched all over but apparently nobody tries to implement these scrappers that they write. I can write a web scrapper in python just fine. Say my scrapper scraps a name from a wikipedia page (John Doe for example), how can I use that name that I get in my website? Another update, I have found pjsrape and PhantomJS. I have only found one stack overflow post and the github examples with aren't very intuitive. If anybody has any experience or better ways to do it I would very much appreciate it

  • Implementing a 'many-to-many' database

    - by Raven Dreamer
    Greetings, stack*overflow* In my database, I already have one table, 'contacts' that contains records of individual people. I also have several other tables in my database which represent "skill sets" that contain records denoting a particular skill. 1) Am I correct in plotting this as a "many-to-many" relationship? (each contact can have multiple skill sets, and each skill set can belong to multiple contacts) 2) I'm new to databases -- do I want to link the tables? 3) Is there a way to implement this in my program (C# + windows forms) such that for any given record in the 'contacts' table, either the names of all associated 'skill set' tables or all the 'skill' records associated with the 'contact' record could be retrieved? (Database is located on SQL Server Express 2008)

  • POST and multiple submit buttons on form (iphone)

    - by Jonathan
    NSString *reqURL = [NSString stringWithFormat:@"%@/login",SERVER_URL]; NSMutableURLRequest *req = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:reqURL]]; [req setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"]; NSData *myRequestData = [NSData dataWithBytes:[@"username=whatever&password=whatever" UTF8String] length: [@"username=whatever&password=whatever" length]]; [req setHTTPMethod: @"POST"]; [req setHTTPBody: myRequestData]; NSData *returnData = [NSURLConnection sendSynchronousRequest:req returningResponse: nil error: nil]; NSString *html = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; I got this code from another question I asked. But what happens if there is more than one submit button. I really have no idea how to ask this question. An example of such situation is on the logout page for this site. There are no fields to enter data into, but there are 2 submit buttons. How can I "simulate clicking" on one of those buttons using code like the above (so not using a UIWebView)

  • Additional information with widgets in django

    - by fromclouds
    I am displaying a django widget, with which I need to display additional information (something like a tool tip) that is attendant to the widget. I essentially have a widget that asks a random question, which is self contained. {{ form.fieldname }} displays the full widget which looks something like (à la the widget's render method): <label for="id_answer">Question:</label> <input type="hidden" name="question_id" value="n" /> <span class="prompt">What is the air-speed velocity of an unladen swallow?</span> <input type="text" name="answer" /> What I'm essentially asking is, is there a way to break out the prompt, so that I can lay the widget out piecemeal? I would like to lay it out not with a call to {{ form.fieldname }} as above, but like: {{ form.fieldname.label }} {{ form.fieldname.prompt }} {{ form.fieldname }} Does anyone know how to do this?

  • Jquery counting elements by class what is the best way to implement this?

    - by 133794m3r
    Ok what i'm trying to do is to count all of the elements in the current page with the same class and then i'm going to use it to be added onto a name for a input form. Basically i'm allowing users to click on an and then by doing so add another one for more of the same type of items. But i can't think of a way to count all of these simply with jquery/javascript. I was going to then name the item as something like name="whatever(total+1)", if anyone has a simple way to do this i'd be extremely grateful as javascript isn't exactly my native tongue and stack overflow usually has a ton of great answers and a great community so i'm hoping my query will not go unheard.

  • How to Not alter font in webpage after opening a file (pdf or jpg) in ASP.NET C#? [closed]

    - by Victor
    Possible Duplicate: How to not alter font in webpage after opening a pdf in ASP.NET C#? Previously I posted this question: How to open files from a specific route in ASP-NET c#? in fact, I have already asked this however it was only a minor question so I guess it wasn't that important in the previous post, so I will ask here. Whenever I open a pdf with: Response.Write("<script>window.open('FilePath');</script>"); All of the font in the page is altered, example, the letter's size increases and some of the letter's colors are switched to black instead of the font that I assigned. Is there a way that I can work around that?? http://imageshack.us/a/img838/5145/beforeja.png http://imageshack.us/a/img546/4760/afterw.png Oh and I noticed that this also happens when you open images like jpg

  • Why is writing a compiler in a functional language easier?

    - by wvd
    Hello all, I've been thinking of this question very long, but really couldn't find the answer on Google as well a similar question on Stackoverflow. If there is a duplicate, I'm sorry for that. A lot of people seem to say that writing compilers and other language tools in functional languages such as OCaml and Haskell is much more efficient and easier then writing them in imperative languages. Is this true? And if so -- why is it so efficient and easy to write them in functional languages instead of in an imperative language, like C? Also -- isn't a language tool in a functional language slower then in some low-level language like C? Thanks in advance, William v. Doorn

  • Insert new row with data computed from other rows

    - by Tyler McHenry
    Suppose I have a MySQL table called MyTable, that looks like this: +----+------+-------+ | Id | Type | Value | +----+------+-------+ | 0 | A | 1 | | 0 | B | 1 | | 1 | A | 2 | | 1 | B | 3 | | 2 | A | 5 | | 2 | B | 8 | +----+------+-------+ And, for each Id, I want to insert a new row with type C whose Value is the sum of the type A and B values for the rows of the same Id. The primary key on this table is (Id, Type), so there's no question of duplication of Id,Type pairs. I can create the rows I want with this query: SELECT MyTable_A.Id AS Id, 'C' AS Type, (A_Val + B_Val) AS Value FROM (SELECT Id, Value AS A_Val FROM MyTable WHERE Type='A') AS MyTable_A JOIN (SELECT Id, Value AS B_Val FROM MyTable WHERE Type='B') AS MyTable_B ON MyTable_A.Id = MyTable_B.Id Giving: +----+------+-------+ | Id | Type | Value | +----+------+-------+ | 0 | C | 2 | | 1 | C | 5 | | 2 | C | 13 | +----+------+-------+ But the question is: How do I use this result to insert the generated type-C rows into MyTable? Is there a relatively simple way to do this with a query, or do I need to write a stored procedure? And if the latter, guidance would be helpful, as I'm not too well versed in them.
