  • PHP fastest method of reading server response

    - by Peter John
    Hi there, im having some real problems with the lag produced by using fgets to grab the server's response to some batch database calls im making. Im sending through a batch of say, 10,000 calls and ive tracked the lag down to fgets causing the hold up in the speed of my application as the response for each call needs to be grabbed. I have found this thread http://bugs.php.net/bug.php?id=32806 which explains the problem quite well, but hes reading a file, not a server response so fread could be a bit tricky as i could get part of the next line, and extra stuff which i dont want. Any help much appreciated!

  • Trying to keep filled bars in a faceted plot

    - by John Horton
    Not sure what I'm doing wrong here. I have this plot: ggplot(data.PE5, aes(ybands,fill=factor(decide))) + geom_bar(position="dodge") which produces: Then I want to facet by a factor, creating two stacked plots w/ dodged, colored bars ggplot(data.PE5, aes(ybands,fill=factor(decide))) + geom_bar(position="dodge") + facet_grid(~group_label) However, I lose the factor-based coloring, which I want to keep:

  • Custom class object in Initialization list

    - by Michael
    I have a class Bar: class Bar { public: Bar(void); ~Bar(void); }; And a class Foo that gets a reference to Bar object as a constructor parameter and needs to save it in a private member bar_ : class Foo { private: Bar& bar_; public: Foo(Bar& bar) : bar_(bar) {} ~Foo(void) {} }; This doesn't compile : overloaded member function not found in 'Parser' missing type specifier - int assumed. Note: C++ does not support default-int Now i suspect couple of things that i need to assure, the second error is for Bar& bar_; declaration in Foo. Do i need to use an explicit constructor when declaring bar_ ? I am interested in learning how the compiler works regarding this matter, so a detailed explanation would be highly appreciated. Thanks.

  • php preg_match pattern to extract a specific information, regex

    - by Michael
    I need to extract a specific Id from a html document but the problem is that the id must not "be used". Here is the html content http://pastebin.com/wF2dx8JZ As you may see there are different html blocks . Some of them contain the "Used" word so I need to extract only the first id which is not used. Basically I can write a simple pattern like : $pattern = "/javascript:tw(.*))/"; preg_match_all($pattern, $content, $matches); $id = $matches[1][0]; However in this case I'm also getting the "ids" which are used so I don't know how to exclude them from the equation . Any idea would be highly appreciated.

  • CSS [custom?] attributes

    - by Michael
    radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

  • Is there a way to morph / convert a circular sprite into a square programmatically?

    - by John
    I have a sprite which is basically just an image of a circle and some content inside. Is there a way that I can programmatically stretch / distort it into something like: I don't care so much about the distortion. The original circular image is 100x100px, and the modified image should also be 100x100px. So its really the content that is being distorted. Can this be done using shaders or some other programmatic way ? The initial circular image is most likely determined at run time, which is why I need to programmatically convert the circular sprite to square. Please do not edit the tags, as the question applies to both versions of cocos2d (iPhone & x), and the solution will most likely work in both regardless of whether one uses C or C++ since the apis are similar, and OpenGL commands work similarly.

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  • C++ method declaration, class definition problem

    - by John Fra.
    I have 2 classes: A and B. Some methods of class A need to use class B and the opposite(class B has methods that need to use class A). So I have: class A; class B { method1(A a) { } } class A { method1(B b) { } void foo() { } } and everything works fine. But when I try to call foo() of class A from B::method1 like this: class B { method1(A a) { a.foo(); } } I get as result compile errors of forward declaration and use of incomplete type. But why is this happening? (I have declared class A before using it?)

  • selecting a row by means of a button ... using didSelectRowAtIndexPath

    - by John Smith
    hey people , I have a question concerning a button I would like to create which selects my previous selected row. This is what I came up so far but since I'm new with the functionality and such I could definately use some pointers I created a toolbar with a button and behind this button is the following action. -(void)clickRow { selectedRow = [self.tableView indexPathForSelectedRow]; [self.tableView:[self tableView] didSelectRowAtIndexPath:selectedRow]; } in my didSelectRowAtIndexPath there is a rootViewController being pushed rvController = [RootViewController alloc] ...etc So what I would like is my function clickRow to select the row and push the new rootviewcontroller (which has the right info since I'm using a tree ). I tried something like this as well -(void)clickRow { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; NSArray *Children = [dictionary objectForKey:@"Children"]; rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; rvController.CurrentLevel += 1; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } The last function works a little but a little is not enough;) For instance if I press the middle row or any other it constantly selects the toprow. thnx all for those of you reading and trying to help

  • Workaround for richfaces combobox hotkey bug

    - by John
    Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

  • Is key 'chord' functionality provided by Win32/.net?

    - by John
    Several MS apps support the concept of chords, like "CTRL+X,Y" which means "holding down CTRL, press X, then Y". Is this a bespoke thing they (and other companies) implement, or is it built into any APIs? It would be nice to be able to set up event handlers or accelerators based on chords rather than write code to do it.

  • Does a program exist for checking two similar directories for file differences?

    - by John Sullivan
    Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • Can you set a gradient brush for a listboxitem background in silverlight?

    - by Michael
    I am looking for a way to set a gradientbrush as the background for a listbox item. I have a DataTemplate defined and have specified a gradient brush but it always appears as the listbox background (i.e. it never shows as a gradient brush). I have been able to set the background of the listbox itself, and I can set the listboxitem's background to a standard color using the "setter" object....but none of these are what I am after. I really want the background on each list item to be a gradient brush. Below is the datatemplate that I have constructed. <ListBox Name="MyListBox" Margin="12,67,12,169"> <ListBox.ItemTemplate> <DataTemplate> <Grid Height="51" VerticalAlignment="Bottom"> <Grid.Background> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FFC9F4D0"/> <GradientStop Color="#FF2AC12A" Offset="0.333"/> <GradientStop Color="#FF35DE35" Offset="1"/> </LinearGradientBrush> </Grid.Background> <Canvas > <dataInput:Label Width="227" Foreground="Yellow" Canvas.Left="158" Canvas.Top="8" Content="{Binding Place}"/> <dataInput:Label Width="146" Foreground="Yellow" Canvas.Left="8" Canvas.Top="8" Content="{Binding Date}"/> <dataInput:Label Content="{Binding People}" Width="346" FontSize="9.333" Foreground="Black" Canvas.Left="166" Canvas.Top="28"/> <!-- <dataInput:Label Width="45" Content="Accept" Foreground="White" Canvas.Left="8" Canvas.Top="28"/> <dataInput:Label Width="45" Content="Decline" Foreground="White" Canvas.Left="57" Canvas.Top="28"/> --> <dataInput:Label Content="SomeText" Width="101" FontSize="9.333" Foreground="White" Canvas.Left="389" Canvas.Top="10"/> <Image Height="21" Width="21" Canvas.Left="500" Canvas.Top="8" Source="Green Button.png"/> </Canvas> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Any Thoughts?

  • Alternative to Windows Azure tables out of the cloud

    - by John Grey
    Hi :) I'm developing a .NET app, which needs to run both on Azure and on regular Windows Servers(2003). It needs to store a few GB of data and SQL Azure is too expensive for me, so I'll use Azure tables in the cloud version. Can you recommend a storage solution, which will run on standalone servers and have an API and behavior similar to Azure tables? From what I've seen Server AppFabric does not include Tables. TIA

  • users see my SMS messages as coming from '1010100001'

    - by John Leonard
    In my application, I ask the user to enter their cell and select their provider. I append the provider's email and create the message and fire via php.mail() The problem is that no matter what the header info is, the message comes from '1010100001' on some phones (like AT&T and the iPhone). When testing on my Verizon phone, I get the proper email address as the sender. Any idea how I can send a clearer message?

  • ASP .NET Added Event Handlers to buttons on Page_Load. Event handlers do not fire the first click, b

    - by John
    Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers are triggered. On the second click, they are triggered. Any ideas? Example of Button Definition Button btn = new Button(); btn.Text = "Click Me Locked Screen"; bth.Click += new EventHandler(Btn_Click); Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something }

  • R: How can I reorder the rows of a matrix, data.frame or vector according to another one.

    - by John
    test1 <- as.matrix(c(1, 2, 3, 4, 5)) row.names(test1) <- c("a", "b", "c", "d", "e") test2 <- as.matrix(c(6, 7, 8, 9, 10)) row.names(test2) <- c("e", "d", "c", "b", "a") test1 [,1] a 1 d 2 c 3 b 4 e 5 test2 [,1] e 6 d 7 c 8 b 9 a 10 How can I reorder test2 so that the rows are in the same order as test1? e.g: test2 [,1] a 10 d 7 c 8 b 9 e 6 I tried to use the reorder function with: reorder (test1, test2) but I could not figure out the correct syntax. I see that reorder takes a vector, and I'm here using a matrix. My real data has one character vector and another as a data.frame. I figured that the data structure would not matter too much for this example above, I just need help with the syntax and can adapt it to my real problem.

  • How are exceptions allocated on the stack caught beyond their scope?

    - by John Doe
    In the following code, the stack-based variable 'ex' is thrown and caught in a function beyond the scope in which ex was declared. This seems a bit strange to me, since (AFAIK) stack-based variables cannot be used outside the scope in which they were declared (the stack is unwound). void f() { SomeKindOfException ex(...); throw ex; } void g() { try { f(); } catch (SomeKindOfException& ex) { //Handling code... } } I've added a print statement to SomeKindOfException's destructor and it shows that ex is destructed once it goes out of scope in f() but then it's caught in g() and destructed again once it goes out of scope there as well. Any help?

  • How much do politics/office intrigue interfere with your day to day tasks at work?

    - by Michael Dorgan
    I'm currently blessed to be employed at a location where politics are pretty much non-existant and management overhead is nearly nil. As I've only worked at this one location for my entire, lengthy career, I have very little frame of reference outside of an occasional Dilbert comic or offhand comment from others about just how bad office politics and management interference get in the way of getting your code done elsewhere. While I'm not actively looking for a new job, this one point has made me quite reluctant to even look seriously elsewhere. My question is, just how much are politics a way of life in larger companies - in or out of the game industry and how much does it affect your day to day satisfaction?
