• Working with Japanese filenames in PHP 5.3 and Windows Vista?

  - by Jon

  I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with: header('Content-Type: text/html; charset=UTF-8'); setlocale(LC_ALL, 'en_US.UTF8'); mb_internal_encoding("UTF-8"); At the top (Exporting as plain text until I can sort this out). What can I do? I need this to work and I don't have much time.

• [FLEX 3] Placing images into a Collage Canvas

  - by Bridget

  I've got an array of different sized images. I want to place these images on a canvas in a sort of automated collage. Does anyone have an idea of how to work the logic behind this concept? All my images have heights divisible by 36 pixels and widths divisible by 9 pixels. They have mouseDown functions that allow you to drag and drop. When dropped the image goes to the closest x point divisible by 9 and y point divisble by 36. There is a grid drawn on top of the canvas. I've sorted the array of images based on height, then based on their widths. imagesArray.sortOn("height", Array.NUMERIC | Array.DESCENDING); imagesArray.sortOn("width", Array.NUMERIC | Array.DESCENDING); I'd like to take the largest image ( imageArray[0] ) to put in corner x,y = 0,0. Then randomize the rest of the images and fit them into the collage canvas.

• How to make a rectangle on screen invisible to screen capture ?

  - by Kesarion

  How can I create a rectangle on the screen that is invisible to any sort of screen capture(printscreen or aplications) ? By create a rectangle on screen I mean something like this: #include <Windows.h> #include <iostream> void drawRect(){ HDC screenDC = ::GetDC(0); ::Rectangle(screenDC, 200, 200, 300, 300); ::ReleaseDC(0, screenDC); } int main(void){ char c; std::cin >> c; if (c == 'd') drawRect(); std::cin >> c; return 0; } I'm using Visual Studio 2010 on Windows XP

• Arrange 0's & 1's in a array

  - by Ganesh M

  This is one of an interview question which I had recently. I would like to know others perception of approach for this problem. Question: You are given a structure which holds an employee details with two elements as int Deptartment and string Name. struct Employee { string Name; int Dept; } You are given details of N Employees among which there are N/2 employees Dept are 0's and N/2 employees dept are 1's arranged in some random order. You need to sort the employee details based on their Dept value and it should be stable i.e., the order of 1s and 0s in the original record should be maintained. For example, given the following sample data: Name Dept X1 0 X2 1 X3 0 X4 1 X5 0 after sorting the result should be: Name Dept X2 1 X4 1 X1 0 X3 0 X5 0 The algorithm should be stable and the complexity should be o(N), with constant space for additional variables (which means sorting should be done in-place).

• Using Javascript to detect the bottom of the window and ignoring all events when a request is loading

  - by Aaron Reba

  I have an anonymous function to detect the user has scrolled to the bottom of the window. Inside of the anonymous function, I have a call to a database that takes a while to complete. var allowing_more = 1; $(window).scroll(function() { if (allowing_more == 1){ if ($(window).scrollTop() + $(window).height() == $(document).height()) { allowing_more = 0; //query allowing_more = 1; } } }); In this time, if the user scrolls to the bottom of the window again, it seems a queue is made holding the occurences the user scrolled to the bottom of the window while the query was loading. Upon completing of the query, these occurences are then executed. I have a boolean statement to detect if the anonymous function is accepting more query requests but this seems to be ignored. Is there some sort of way to ignore an anonymous function temporarily and re-enable it?

• How to get the right row in a sorted DataView?

  - by ZeissS

  Hi, I have a DataGrid containing a small table. Until now, I had a double click handler on this grid which iterated over all rows to find the selected one: DataTable table = (DataTable)this.dataGrid.DataSource; int selectedRow = -1; for (int i=0; i<table.Rows.Count; i++) if (this.dataGrid.IsSelected(i)) selectedRow = i; break; } if ( selectedRow != -1 ) { DataRow row = table.Rows[selectedRow]; // More code ... } Problem: When the user clicks on a column header and sort the table, table.Rows does not return the right rows. It still contains the unsorted rows. How can I get the right column?

• Rails 3 - raw/html_safe not working in some cases?

  - by Frexuz

  I'm having difficulties with output not being encoded even though I'm using raw or html_safe. This one is writing out the &nbsp in my final HTLM page. def build_tag_cloud(tag_cloud, style_list) tag_cloud.sort!{ |x,y| x.permalink <=> y.permalink } max, min = 0, 0 tag_cloud.each do |tag| max = tag.followers.to_i if tag.followers.to_i > max min = tag.followers.to_i if tag.followers.to_i < min end divisor = ((max - min) / style_list.size) + 1 html = "" tag_cloud.each do |tag| name = raw(tag.name.gsub('&','&amp;').gsub(' ','&nbsp;')) link = raw(link_to "#{name}", {:controller => "/shows", :action => "show", :permalink => tag.permalink}, :class => "#{style_list[(tag.followers.to_i - min) / divisor]}") html += raw("<li>#{link}</li> ") end return raw(html.to_s) end What is allowed in using raw and html_safe? And how should my example above be fixed?

• 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!

• how to google a symbol keyword like "$?"

  - by ZhengZhiren

  i saw a trick in a book: in a linux shell, we can use &? to get the return value of a command. For example,we run a command,if it exit normally, the return value is 0. And then we type $?,we will get 0 in the screen. i want to google this kind of usage, so i have to type these two symbol $? in the search blank.But the search engine just return nothing to me... i have looked at the google help page, but still can't find a solution. so my question is: how can i search with this kind of keyword. or if you can give me some advise of the usage of $? or sort of thing, that will be also appreciated.

• PHP Session Array Value keeps showing as "Array"

  - by Nerathas

  Hello, When sending data from a form to a second page, the value of the session is always with the name "Array" insteed of the expected number. The data should get displayed in a table, but insteed of example 1, 2, 3 , 4 i get : Array, Array, Array. (A 2-Dimensional Table is used) Is the following code below a proper way to "call" upon the stored values on the 2nd page from the array ? $test1 = $_SESSION["table"][0]; $test2 = $_SESSION["table"][1]; $test3 = $_SESSION["table"][2]; $test4 = $_SESSION["table"][3]; $test5 = $_SESSION["table"][4]; What exactly is this, and how can i fix this? Is it some sort of override that needs to happen? Best Regards.

• html links & hover events over certain locations on an image.

  - by Tommy

  So i created a web site a long time ago using a designer alot like frontpage + expression design put together, and since then Ive gotten more into coding, and I'm learning html, CSS, and all that good stuff.. and i have this re-designed header that Ive made here: http://prntscr.com/8zct So what I need to know, is how i can get it so that when a user clicks on one of the links in the header design it will redirect to a page. and also if possible, how to make it so when a user hovers over a link a drop down may appear with other options. As me being quite new to this sort of stuff, could anybody help me achieve this? PS. I'm working in Visual Studio with ASP. but that doesn't change anything about the html and css stuff. just letting you guys know.

• Printing contents of a dynamically created iframe from parent window

  - by certainlyakey

  I have a page with a list of links and a div which serves as a placeholder for the pages the links lead to. Everytime user clicks on a link an iframe is created in the div and its src attribute gets the value of the link href attribute - simple and clear, sort of external web pages gallery. What i do have a problem with is printing the contents of the iframe. To do this i use this code: function PrintIframe() { frames["name"].focus(); frames["name"].print(); } The issue seems to be that iframe is created dynamically by JQuery - when I insert an iframe right into the html code, the browser prints the external page all right. But with the same code injected by JavaScript nothing happens. I tried to use JQ 1.3 'live' event on "Print" link, no success. Is there a way to overcome this?

• 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?

• 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

• Few files out of sync but GIT doesn't seem to notice.

  - by doublejosh

  I have two repos that claim to be clean. One was originally cloned from the other and is used for dev work. There are a few files that I can see are not the same. However when I try pulling either way it says everything is up to date. How is this possible? Did that file miss a commit somehow? ...but shouldn't the difference be noticed regardless? Do I need a refresh of some sort?

• 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 :)

• Why do C# and Java require everything to be in a class?

  - by Javier Badia

  It seemed like this question should have been asked before, but searching found nothing. I've always wondered what's the point of making us put every bit of code inside a class or interface. I seem to remember that there were some advantages to requiring a main() function like C, but nothing for classes. Languages like Python are, in a way, even more object oriented than Java since they don't have primitives, but you can put code wherever you want. Is this some sort of "misinterpretation" of OOP? After all, you can write procedural code like you would in C and put it inside a class, but it won't be object oriented.

• 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)?

• 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

• DB fields not showing up in association custom queries?

  - by Kevin

  I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

• 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?

• comparison between point and integer

  - by LawVS

  Right, basically I want to add two numbers together. It's for a working hours calculator and I've included parameters for a night shift scenario as an if statement. However, it now mucks up the day shift pattern. So I want to sort out that if the start time is below 12, then it'll revert to the original equation shown in the code instead of the if statement. -(IBAction)done:(id)sender { int result = [finishHours.text intValue] - [startHours.text intValue]; totalHours.text = [NSString stringWithFormat:@"%d", result]; if (result < 0) { totalHours.text = [NSString stringWithFormat:@"%d", result * -1]; } if (result < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result + 24]; } if (startHours < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result - 24]; }

• 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.

• How to match data between columns to do the comparasion

  - by NCC

  I do not really know how to explain this in a clear manner. Please see attached image I have a table with 4 different columns, 2 are identical to each other (NAME and QTY). The goal is to compare the differences between the QTY, however, in order to do it. I must: 1. sort the data 2. match the data item by item This is not a big deal with small table but with 10 thousand rows, it takes me a few days to do it. Pleas help me, I appreciate. My logic is: 1. Sorted the first two columns (NAME and QTY) 2. For each value of second two columns (NAME and QTY), check if it match with first two column. If true, the insert the value. 3. For values are not matched, insert to new rows with offset from the rows that are in first two columns but not in second two columns
