  • CakePHP and jQuery - Unobtrusive actions

    - by fortysixandtwo
    I'm trying to make an unobtrusive action for deleting bookmarks in CakePHP. Allthough it's working just fine, I suspect there must be a better way to do this. Could someone please point me in the right direction? function delete($id = null) { $ok = $this->Bookmark->delete($id); if($this->RequestHandler->isAjax()) { $this->autoRender = false; $this->autoLayout = false; $response = array('status' => 0, 'message' => 'Could not delete bookmark'); if($ok) { $response = array('status' => 1, 'message' => 'Bookmark deleted'); } $this->header('Content-Type: application/json'); echo json_encode($response); exit(); } // Request isn't AJAX, redirect. $this->redirect(array('action' => 'index')); }

  • Subversion: Ignore a Directory in the Repo on Commit

    - by Charles
    I have all the boost header files in this repository and when I do a check in it takes a really long time to scan all those files that will never change. Because I want users that checkout the project to be able to compile without installing boost I am in a pickle. I want to checkout everything, and then ignore updates (there will never be any) on a directory. Tortoise svn has a ignore-on-commit change list, but I cannot find anyway to add an entire directory to this list, and I do not fancy the idea of 'modifying' all the boost files so I can add them to this change list. Is there a simple solution?

  • How to deal with many to many relationships with NSFetchedResultsController?

    - by Phil Yates
    OK so I have two entities in my data model (let's say entityA and entityB), both of these entities have a to-many relationship to each other. I have setup a NSFetchedResultsController to fetch a bunch of entityA. Now I'm trying to have the section names for the tableview be the title of entityB. sectionNameKeyPath:@"entityB.title" Now this causes a problem, where by the section name returned from that relationship appears to be ({title1}) or ({title1,title2...titleN}) obviously depending on how many different entityB's are involved. This doesn't look great in a tableview and doesn't group the objects as I would like. What I would like is a section per entityB title with entityA appearing under each section, under multiple sections if necessary. I'm at a loss as how I am supposed to achieve this whether I need to update the predicate to get the entity to appear multiple times or whether I need to update the section and header functions to do some processing as the controller loops through the objects. Any help is appreciated :) Thanks

  • paypal IPN php script

    - by pol
    I just realized that my paypal ipn handler in php doesn't work anymore (and I change nothing), I use the sample php script provided by paypal. I tried to isolate the problem by making several test, and at this time I can say that the problem is not the "VERIFIED" or the "INVALID" thing but comes from these lines: [...] fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); if (strcmp ($res, "VERIFIED") == 0) { // check the payment_status is Completed [...] Anyone know if paypal change something or why it doesn't work? thanks' ps: if I put my code before all the paypal tests (before the line "if (!$fp)") it just works fine

  • How to Store Cookies in Ruby?

    - by viatropos
    I am programmatcally accessing authenticated content in my CDN on Google App Engine, and it's returning a cookie that I'm supposed to store: {"set-cookie"=>"ACSID=cookie-hash; expires=Mon, 12-Apr-2010 01:56:06 GMT; path=/"} What do I do with that? This is my first time dealing with Cookies. I can put in the header of the next request, but what's the recommended way to store that? I'm testing this with irb in the console and when I exit and try again, the cookie is gone. How do I save it for a few days/weeks? I'm using pure ruby without Rails or anything. Thanks so much.

  • Setting foreground color for HSSFCellStyle is always coming out black

    - by Ascalonian
    I am using POI to create an Excel spreadsheet in Java. I have the following code used for creating a header row: HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet("Report"); // some more code HSSFRow row = sheet.createRow(0); HSSFCell cell = row.createCell(cellNumber); HSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setFillBackgroundColor(HSSFColor.GREY_25_PERCENT.index); cellStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND); HSSFFont font = wb.createFont(); font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); font.setColor(HSSFColor.WHITE.index); cellStyle.setFont(font); cell.setCellStyle(cellStyle); The issue I am having is that setting the fill background color on the cell always comes out black, no matter what color I pick. What am I doing wrong? If I don't use the "setFillPattern" line, no color shows up at all.

  • Disabling a CellEditingTemplate programmatically in in a Silverlight DataGrid

    - by bplus
    I have a Silverlight Datagrid, I'd like to make certain cells readonly programmatically. Specifically I have a CellEditingTemplate, I'd like to turn the cell editing off or on depending on the value of CategoryTypeName (see the xmal below). <local:DataGridTemplateColumn Header="Category" > <local:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding CategoryTypeName}"/> </DataTemplate> </local:DataGridTemplateColumn.CellTemplate> <local:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox Width="90" x:Name="CategoryCombo" ItemsSource="{Binding CategoryTypes}" DisplayMemberPath="Name" SelectionChanged="CategoryCombo_SelectionChanged" /> </DataTemplate> </local:DataGridTemplateColumn.CellEditingTemplate> </local:DataGridTemplateColumn> Is there a way to do this? Any help would be very much appreciated. Thanks in advance.

  • Tornado Web & Persistent Connections

    - by Engrost
    How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like that: class MainHandler(RequestHandler): count = 0 @asynchronous def post(self): #get header content type content_type = self.request.headers.get('Content-Type') if not content_type in ACCEPTED_CONTENT: raise HTTPError(403, 'Incorrect content type') text = self.request.body self.count += 1 command = CommandObject(text, self.count, callback = self.async_callback(self.on_response)) command.execute() def on_response(self, response): if response.error: raise HTTPError(500) body = response.body self.write(body) self.flush() execute calls callback when finishes. is my asumption right that with things that way post will be called many times and for one connection count will increase with each httprequest from client? but for each connection I will have separate count value?

  • WITH_OBJECT_HEADERS enabled GC from Dalvik?

    - by Wonil
    Hello, As I know Dalvik VM does not support generational GC as default. But, I found "WITH_OBJECT_HEADERS" compilation flag which could be related with generational GC from HeapInternal.h file. typedef struct DvmHeapChunk { #if WITH_OBJECT_HEADERS u4 header; const Object *parent; const Object *parentOld; const Object *markFinger; const Object *markFingerOld; u2 birthGeneration; u2 markCount; u2 scanCount; u2 oldMarkGeneration; u2 markGeneration; u2 oldScanGeneration; u2 scanGeneration; #endif Does anyone try to build Dalvik with this option enabled? Do you know anything about generational GC support from Dalvik? Regards, Wonil.

  • Master report and subreport communication

    - by Dave Jarvis
    How do you determine whether the content for the detail page being displayed is filled by a specific subreport? For example, consider two subreports on the same master report, using different detail bands: Detail 1 Detail 2 The header on the master report should show certain fields on pages where the subreport in the Detail 2 band is printed. A Return Value from the subreport in the Detail 2 band only seems to be set after the report has finished, even though the Reset type for the variable (in both the master and the subreport) is set to Page. (Setting it to Report also does not help.)

  • Steps in subclassing UINavigationController

    - by RickiG
    Hello I would like to subclass the UINavigationController to get some more freedom in regards to the appearance of the controller. I have some graphics for the different parts, bars, buttons, text etc. Looking at the UINavigationController header file I get little help, I don't know where to start out. I have never subclassed/overridden a UIKit component before, it seems it is a bit like playing Sherlock Holmes. What is the approach? How do I know what to override to get a a specific piece of graphics "injected" the correct place? Do I need to subclass UINavigationBar, UIBarButtonItem etc. etc to get the complete customized look? How do I know if something is off limits in regards to being approved by Apple? Hope someone can point me in the right direction, I have only been able to find examples of changing small parts of the controller, not a full customization by subclassing. Am I going about this the wrong way? Thanks:)

  • php variable scope

    - by Illes Peter
    I have two files: index.php /lib/user.php Index contains the form: <div class="<? echo $msgclass; ?>"> <? echo $msg; ?> </div> <form id="signin" action="/lib/user.php" method="post"> ... </form> User.php makes all the processing. It sets $msg to 'some error message' and $msgalert to 'error' in case of any error. At the end of processing it uses header() to redirect to index.php But after redirection $msg and $msgalert get out of scope and index only gets empty vars. How can i fix this?

  • Python urllib3 and how to handle cookie support?

    - by bigredbob
    So I'm looking into urllib3 because it has connection pooling and is thread safe (so performance is better, especially for crawling), but the documentation is... minimal to say the least. urllib2 has build_opener so something like: #!/usr/bin/python import cookielib, urllib2 cj = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) r = opener.open("http://example.com/") But urllib3 has no build_opener method, so the only way I have figured out so far is to manually put it in the header: #!/usr/bin/python import urllib3 http_pool = urllib3.connection_from_url("http://example.com") myheaders = {'Cookie':'some cookie data'} r = http_pool.get_url("http://example.org/", headers=myheaders) But I am hoping there is a better way and that one of you can tell me what it is. Also can someone tag this with "urllib3" please.

  • SDL_BlitSurface() not displaying image?

    - by Christian Gonzalez
    So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed. SDL_Surface* Hello = NULL; SDL_Surface* Screen = NULL; //Sets the size of the window (Length, Height, Color(bits), Sets the Surface in Software Memory) Screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); //Loads a .bmp image Hello = SDL_LoadBMP("Hello.bmp"); //Applies the loaded image to the screen SDL_BlitSurface(Hello, NULL, Screen, NULL); //Update Screen SDL_Flip(Screen); //Pause SDL_Delay(2000); //Deletes the loaded image from memory SDL_FreeSurface(Hello); //Quits SDL SDL_Quit(); return 0; }

  • ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

    - by DennyDotNet
    I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

  • LINQ to SQL: Issue with concurrency

    - by Gib
    I’m working on a sandwich ordering app in ASP.NET MVC, C# and LINQ to SQL. The app revolves around the user creating multiple custom-made sandwiches from a selection of ingredients. When it comes to confirming the order I need to know that there’s enough portions of each ingredient to fulfil all the sandwiches in the user’s order before I commit to the DB as it is possible that an ingredient will go out of stock between adding it to their basket and confirming the order. A bit about the database: Ingredient – Stores ingredient details including number of portions Order – Header table for an order, simply stores the order time OrderDetail – Stores a record of each sandwich in an order OrderDetailItem – Stores each ingredient in each sandwich in an order So basically I’m wondering what the best approach to ensuring that before I add records to Order, OrderDetail and OrderDetailItem I can ensure that the order can be met.

  • WPF DataGrid row validation error count

    - by SuperFloh1234
    Hi! I'm currently facing the problem, that I import an Excel file to a DataGrid. This works pretty fine, but after importing the table, I need to know how many rows are invalid. I have applied several validation rules for the different datatypes, and I have an icon in the row header, that shows up if the row is invalid. But since I have more that 10.000 rows in the grid, I don't want scroll all the way through it to find the errors. Any ideas, how to determine the count of invalid rows (and then maybe bind that to a textbox)? Thx

  • Trying to parse xml, but xmldocument.loadxml() is trying to download?

    - by maxp
    I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

  • Import text file crunching library for Java/Groovy ?

    - by devdude
    In a lot of real life implementations of applications we face the requirement to import some kind of (text) files. Usually we would implement some (hardcoded?) logic to validate the file (eg. proper header, proper number of delimiters, proper date/time value,etc.). Eventually also need to check for the existence of related data in a table (eg. value of field 1 in text file must have an entry in some basic data table). While XML solves this (to some extend) with XSD and DTD, we end up hacking this again and again for proprietary text file formats. Is there any library or framework that allows the creation of templates similar to the xsd approach ? This would make it way more flexible to react on file format changes or implement new formats. Thanks for any hints Sven

  • Outputing resized animated gif to browser using imagick

    I intent to resize an animated gif and outputing it to the browser on-the-fly. My problem is that when I save the resized image it is of good quality, but if I echo it to the browser it is of poor quality and the animation is removed. Here is the code:` header("Content-type:image/gif"); try { /* Read in the animated gif */ $animation = new Imagick("images/nikks.gif"); /*** Loop through the frames ***/ foreach ($animation as $frame) { /*** Thumbnail each frame ***/ $frame->thumbnailImage(200, 200); /*** Set virtual canvas size to 100x100 ***/ $frame->setImagePage(200, 200, 0, 0); } /*** Write image to disk.

  • Can a .csv file be used as a data source in Visual Studio 2008?

    - by Kevin
    I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a SQL Server database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data. Also, I should mention that this program is a stand-alone console program with no user interface.
