  • How to read any email account from a domain using C#?

    - by Brendan Enrick
    I guess this is sort of two questions that are tied together. Related questions have discussed how to read and parse email using pop3. I need to be able to do this, however, I want this to be able to work with any email address I need. I am trying to allow users to submit content by emailing it to a unique email address, which will automatically know to which account the content should be associated. Is there a good way to create these email addresses on the fly and check these email accounts so for content submissions? Alternatively is there a way to make a "wildcard" email account which gets all of the email sent to the domain and allows me to see what the to address was?

  • Change the default output folder for a java command when executed by php

    - by jax
    I am trying to run a java command like this in a PHP Joomla Component. It works, however, the files generated from the command are written to /administrator and I want them to be written to the location where the Java command resides ie. /administrator/com_mycomponent/java/MyJavaApp.jar //run the command $javaCommand = "$javaCommand -jar $keyGeneratorFile $appName"; $response = exec($javaCommand); if(empty($response)) { JError::raiseError(500, "Key Generation failed for command: $javaCommand"); } What can I do? Is there some sort of option I can use with the java command?

  • How to use GPS data like the double value returned by getLatitude()?

    - by Dan
    I have been searching quite a bit for an answer, but maybe I'm just not using the correct terminology. I am creating an app that will access a database to return a list of other users that are within a certain distance of the users location. I've never worked with this type of data, and I don't really know what the values mean. I'd like to do all the calculations on the backend with either MySQL or PHP. Currently, I am storing the latitude and longitude as doubles within the database. I can access them and store them, but I have no idea how I might be able to sort them based on distance. Perhaps I should be using a different type or some technique that is common in this area. TIA.

  • How to Print reports in Silvelright 4

    - by lightmeetsdark
    I am wondering if there is anything built in to Silverlight, or possibly c# to allow for printing reports? I'd be happy with any number of methods: exporting files to a pdf format and printing from there, exporting as a text document of some sort and printing from there, or just simply showing the print dialog from the web application itself. I know there are ways to do this in C#, but the c# code-behind is different for many things in Silverlight applications and I can't seem to find anything that will work. So if anyone has any ideas on things I could try it would be very much appreciated! Thank you!

  • jquery/ajax load new content when available

    - by Tim
    I know this is quite a vague question -- sorry about that. If I have a forum, shoutbox or something similar where users enter and submit data, running on PHP and MySQL, what is the best way to have the newly submitted content automatically display on the page for all users when it is submitted? Much like a live newsfeed, if you like... The effect sort-of works here at stackoverflow, when you are answering a question you are told when new answer is submitted. I want to test for newly submitted content and then display it automatically. Any suggestions? Many thanks :)

  • Sorting a listview (Win32/C++)

    - by Zenox
    I'm trying to sort a listview when the user clicks on the column header. I am catching the LVN_COLUMNCLICK notification like so: case LVN_COLUMNCLICK: { NMLISTVIEW* pListView = (NMLISTVIEW*)lParam; BOOL test = ListView_SortItems ( m_hDuplicateObjectsList, ListViewCompareProc, pListView->iSubItem ); break; } However it seems to fail. My test variable is FALSE and my ListViewCompareProc never gets hit (it has a simple return 1 while I am trying to hit a debug point inside of it). Is there something I am missing for sorting a listview?

  • Git is deleting an ignored file when i switch branches

    - by Max Williams
    I have one branch (let's call it B) that ignores a certain file, which isn't ignored in some other branches (eg branch A). When i switch from branch B to branch A, then back to B again, the file has been deleted. Is this normal? I can sort of see how it would happen, in the sense that branch B thinks it's not there, and branch A thinks that it is, so when i go back to B it 'tidies it away'. But it's kind of annoying. Any suggestions? thanks, max

  • Speedup C++ code

    - by Werner
    Hi, I am writing a C++ number crunching application, where the bottleneck is a function that has to calculate for double: template<class T> inline T sqr(const T& x){return x*x;} and another one that calculates Base dist2(const Point& p) const { return sqr(x-p.x) + sqr(y-p.y) + sqr(z-p.z); } These operations take 80% of the computation time. I wonder if you can suggest approaches to make it faster, even if there is some sort of accuracy loss Thanks

  • How to test that invalid arguments raise an ArgumentError exception using RSpec?

    - by John Topley
    I'm writing a RubyGem that can raise an ArgumentError if the arguments supplied to its single method are invalid. How can I write a test for this using RSpec? The example below shows the sort of implementation I have in mind. The bar method expects a single boolean argument (:baz), the type of which is checked to make sure that it actually is a boolean: module Foo def self.bar(options = {}) baz = options.fetch(:baz, true) validate_arguments(baz) end def self.validate_arguments(baz) raise(ArgumentError, ":baz must be a boolean") unless valid_baz?(baz) end def self.valid_baz?(baz) baz.is_a?(TrueClass) || baz.is_a?(FalseClass) end end

  • How to figure out "progress" while sorting?

    - by Mehrdad
    I'm using stable_sort to sort a large vector. The sorting takes on the order of a few seconds (say, 5-10 seconds), and I would like to display a progress bar to the user showing how much of the sorting is done so far. But (even if I was to write my own sorting routine) how can I tell how much progress I have made, and how much more there is left to go? I don't need it to be exact, but I need it to be "reasonable" (i.e. reasonably linear, not faked, and certainly not backtracking).

  • Linux How to print all the files with the same prefix after searching for them?

    - by Alyx
    I need to search through a directory which contains many sub directories, each which contain files. The files read as follows question1234_01, where 1234 are random digits and the suffix _01 is the number of messages that contain the prefix, meaning they are apart of the same continuing thread. find . -name 'quest*' | cut -d_ -f1 | awk '{print $1}' | uniq -c | sort -n example output: 1 quest1234 10 quest1523 This searches for all the files then sorts them in order. What I want to do is print all the files which end up having the most occurrences, in my example the one with 10 matches. So it should only output quest1523_01 - 11

  • Can I load a 32 bit DLL into a 64 bit process on Windows?

    - by Lee
    I recently upgraded a c# windows service to run as a 64 bit .net process. Normally, this would be trivial, but the system makes use of a 32-bit DLL written in C++. It is not an option to convert this DLL to 64 bit, so I wrapped the DLL in a separate 32 bit .net process and exposed a .net interface via remoting. This is quite a reliable solution, but I would prefer to run the system as a single process. Is there any way I can load my 32 bit DLL into a 64 bit process and access it directly (perhaps through some sort of thunking layer)?

  • Any custom/third party Visual C# text box Controls with extra features?

    - by PlaZmaZ
    I'm writing a program that uses the textbox in visual C# to read a log file. When dealing with very large amounts of text, writing to the textbox is incredibly slow. The textbox also lacks many features. Are there any custom textbox controls that are faster, or even a sort of embedded editor (with ability to highlight certain words, indent, input bookmarks)? Many of the features I want are programmable, but it would be nice if there was a faster textbox or one that already had these features :) Thanks.

  • Animation with CGPoint in for loop

    - by user1066524
    I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

  • Ruby on Rails: Best way to save search queries in a database

    - by Adam Templeton
    For a RoR app I'm helping develop, I need to save all search queries in a database so I can analyze them later. My plan right now is to create a Result model and table, and just save each search query's text in that table, along with a user's ID, the time, etc. However, the app has about 15,000 users, so I'm afraid the single table approach won't be super efficient when it comes time to parse that data. (The database is setup via MySQL, if that factors in at all.) Am I just being paranoid? Is there a Ruby gem that handles this sort of thing, or a better approach I could take? Any input would be appreciated.

  • Domain Redirection While Maintaining Original URL

    - by Steve
    I have two domains ("this_site.com" and "that_site.com") that I want to point to the same place (same set of files). BUT What I really want to do is maintain the original URL in the address bar while the visitor accesses the different pages. Example: The primary domain holding the web files is "this_site.com". If I type in "that_site.com" in the address bar, I want the address bar to keep displaying "that_site.com" no matter where they go on the web site. Normal domain redirection causes the URL displayed in the address bar to change to the 'master' domain (i.e. the visitor that typed in "that_site.com" will see the address bar's URL change to "this_site.com"). Is there some sort of .htaccess trick that I can employ to do this? What I'm trying to do is NOT confuse visitors who visit one URL and find themselves on a different URL as well as avoid the additional expense and trouble of having to maintain two separate hosting accounts.

  • What do I need to learn to make a website that can make a text file?

    - by lala
    I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

  • How can I tell what is using the memory when there is a heap overflow in Java?

    - by Grae
    Hi all, I know a little about profiling, but what I am particularlly insterest in, is what has all the memory when I get these heap over flow exceptions. I will start getting them after about a hour of debugging. I am hoping there is some sort of dump or something, that I can use to get a list of what instances are around at the time the program starts. By the way, sorry if this is a lazy question. I really shoud put sometime in learning about profiling. Grae

  • C# 3.5 Merge 2 lists of 2 different types

    - by Ehsan
    I have 2 generic Lists List<type1> L1 , List<type2> L2 in C# 3.5 Problem: type1 has an attribute called "key1" and type2 has an attribute called "key2" How to merge L1 and L2 on key1 = key2. Both lists are unsorted but I'm welcome to any ideas on how to sort the lists based on the attribute. I'd like to be able to merge the two lists on a key. I know it's not a dictionary and it would've been nice if it was but there is a very specific reason why they are lists which I will not get in to because that is irrelevant.

  • Silently binding a variable instance to a class in C++?

    - by gct
    So I've got a plugin-based system I'm writing. Users can create a child class of a Plugin class and then it will be loaded at runtime and integrated with the rest of the system. When a Plugin is run from the system, it's run in the context of a group of plugins, which I call a Session. My problem is that inside the user plugins, two streaming classes called pf_ostream and pf_istream can be used to read/write data to the system. I'd like to bind the plugin instance's session variable to pf_ostream and pf_istream somehow so that when the user instantiates those classes, it's already bound to the session for them (basically I don't want them to see the session internals) I could just do this with a macro, wrapping a call to the constructor like: #define MAKE_OSTREAM = pf_ostream_int(this->session) But I thought there might be a better way. I looked at using a nested class inside Plugin wrapping pf_ostream but it appears nested classes don't get access to the enclosing classes variables in a closure sort of way. Does anyone know of a neat way to do this?

  • How do I run my application while a UAC dialog window is showing?

    - by Ray
    I have an application that I wrote in .NET. It needs to remain running and have access the desktop that the UAC dialog windows open on and interact with that desktop using keyboard and mouse events. It's sort of like a VNC program. Imagine you are running a VNC program and a UAC window pops up, you want your VNC program to still be able to control the desktop with the UAC window in it so that the user can move the mouse and click the OK button on the UAC dialog. Can anyone tell me how I would go about doing that? Thanks

  • View OS X Desktop on windows remotely at higher resolution then hosting machine

    - by Elijha
    I have a new macbook air 11, which I do some web based programming on, I have a windows box with a 1920x1200 display which I'd like to use to view the mac desktop and keep working at home when I can - taking advantage of the higher resolution screen and full sized keyboard/mouse. I don't think VNC or such is the answer I'm looking for as it would restrict the display to the airs 1366x768 - negating the main benefit more lines of text on screen. From some rudimentary googleing I think I'm after some sort of x-windows / x-11 remote display. But I'm not a Linux user and any discussion seems to be about linux os x or windows Linux setups. Can anyone provide a clear set of instructions on how to do this or an application that can do this.

  • The case of the mysterious MySQL caching across restarts

    - by shanusmagnus
    I found a very slow MySQL query in my web app. The weird thing is that the query is only slow the first time it's executed, despite the fact that the query_cache is set to its default (query_cache_size 0) like so: mysql> show variables like 'query%'; +------------------------------+---------+ | Variable_name | Value | +------------------------------+---------+ | query_alloc_block_size | 8192 | | query_cache_limit | 1048576 | | query_cache_min_res_unit | 4096 | | query_cache_size | 0 | | query_cache_type | ON | | query_cache_wlock_invalidate | OFF | | query_prealloc_size | 8192 | +------------------------------+---------+ The even weirder thing is that this speedup persists even after the MySQL server has been stopped and restarted (I'm using OSX, and perform this restart using the system preferences pane.) The only way I can re-create the poor performance of the initial query is by rebooting the system. So my question is: how is this happening? Obviously some sort of caching at work, but where? And how does it persist across database restarts? This query is mediated through our web app, which comes via PHP/Apache, but there are no extra bells and whistles, and the curious caching also persists across Apache restarts. Help?

  • Throwing an AggregateException in my own code

    - by Pat
    How should I go about collecting exceptions and putting them into an AggregateException to re-throw? For my specific code, I have a loop and will have zero or more exceptions thrown from a part of the code. I was hoping to just add the new exceptions to the AggregateException as they arise, but the documentation sort of indicates that it should be constructed with all the Exceptions at once (there is no method to add an Exception to the object). And what about creating a new AE every time and just including the previous AE in the list of exceptions? Seems a hokey way to do it. Any better ideas?
