  • Sending mass email using PHP

    - by Alan
    I am currently writing a music blog. The administrator posts a new article every 2-3 days. Once the administrator posts an article, a mass email will be sent to around 5000 subscribers immediately. What is the best way to implement the mass mail feature? Does the following function work? function massmail() { $content = '...'; foreach ($recipients as $r) { $_content = $content . '<img src="http://xxx/trackOpenRate.php?id='.$r.'">'; mail($r, 'subject', $_content); } } Another question: If all 5000 subscribers are using Yahoo Mail, will Yahoo treat it as a DDOS attack and block the IP address of my SMTP server?

  • Pig: Count number of keys in a map

    - by Donald Miner
    I'd like to count the number of keys in a map in Pig. I could write a UDF to do this, but I was hoping there would be an easier way. data = LOAD 'hbase://MARS1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( 'A:*', '-loadKey true -caching=100000') AS (id:bytearray, A_map:map[]); In the code above, I want to basically build a histogram of id and how many items in column family A that key has. In hoping, I tried c = FOREACH data GENERATE id, COUNT(A_map); but that unsurprisingly didn't work. Or, perhaps someone can suggest a better way to do this entirely. If I can't figure this out soon I'll just write a Java MapReduce job or a Pig UDF.

  • Twitter Trends API weekly.json causing error "Cannot use object of type stdClass as array"

    - by tucson
    I have the following PHP code: $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$URL); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $result = curl_exec($ch); curl_close($ch); $obj = json_decode($result); foreach ($obj[0]->trends as $trend) echo utf8_decode($trend->name); which works fine for URL #1 (into the variable $URL): http://api.twitter.com/1/trends/1.json?exclude=hashtags but causes an error "Cannot use object of type stdClass as array" for URL #2: http://api.twitter.com/1/trends/weekly.json?exclude=hashtags I have searched for a while, but can't figure out a code to fix this and handle both URLs. Any help would be much appreciated.

  • strategy for observer pattern?

    - by fayer
    I want to use observer pattern for a logging system. We have got logObservers and logObservables. The class that will have to log something will implement iLogObservable and include these methods: private $logObservers = array(); public function addLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function removeLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function write($type, $message) { foreach($this->logObservers as $logObserver) { $logObserver->log($level, $message); ; } } Then I noticed, that a lot of classes that will use logging will have these methods and I have to copy paste. So isn't it better to have these methods in a class I call LogObservable or just Log and then use strategy (instantiate this class inside all classes that will have to log). When I change the methods in Log, all logObservables will be affected. However, I have not seen anyone use observer pattern with strategy pattern yet, but it seems to be very efficient and remove the duplications. What do you think?

  • Using MEF to build a tabbed application dynamically

    - by Mmarquee
    I'm rather taken with MEF and plan to use it to build a demo application to load different tabs. I am a begineer at MEF and WPF and although MEF is loading the assemblies I'm stuck at loading the controls into the TabItem I have created. My code looks a bt like this .. foreach (var page in pages) { TabItem item = new TabItem(); item.Header = page.PageTitle; /// Errm??? // Add each page tcPageControl.Items.Add(item); } The tabs are Pages, so I might be doing it totally wrong, and any help would be appreciated. Thanks in advance

  • Relative XPath selection using XmlNode (c#)

    - by maxp
    Say i have the following xml file: <a> <b> <c></c> </b> <b> <c></c> </b> </a> var nodes = doc.SelectNodes("/a/b"); will select the two b nodes. I then loop these two nodes suchas: foreach (XmlNode node in nodes) { } However, when i call node.SelectNodes("/a/b/c"); It still returns both values and not just the descendants. Is it possible to select nodes only descening from the current node?

  • PHP Dynamic Breadcrumb

    - by Adrian M.
    Hello, I got this code from someone and it works very well, I just want to remove the link from the last element of the array: //get rid of empty parts $crumbs = array_filter($crumbs); $result = array(); $path = ''; foreach($crumbs as $crumb){ $path .= '/' . $crumb; $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb)); $result[] = "<a href=\"$path\">$name</a>"; } print implode(' > ', $result); This will output for example: Content Common File I just want a to remove the link from the last item - "File" to be just plain text.. I tried myself to count the array items and then if the array item is the last one then to print as plain text the last item.. but I'm still noob, I haven't managed to get a proper result.. Thank you!

  • Parse string to create a list of element

    - by Nick
    I have a string like this: "\r color=\"red\" name=\"Jon\" \t\n depth=\"8.26\" " And I want to parse this string and create a std::list of this object: class data { std::string name; std::string value; }; Where for example: name = color value = red What is the fastest way? I can use boost. EDIT: This is what i've tried: vector<string> tokens; split(tokens, str, is_any_of(" \t\f\v\n\r")); if(tokens.size() > 1) { list<data> attr; for_each(tokens.begin(), tokens.end(), [&attr](const string& token) { if(token.empty() || !contains(token, "=")) return; vector<string> tokens; split(tokens, token, is_any_of("=")); erase_all(tokens[1], "\""); attr.push_back(data(tokens[0], tokens[1])); } ); } But it does not work if there are spaces inside " ": like color="red 1".

  • empty() not a valid callback?

    - by user151841
    I'm trying to use empty() in array mapping in php. I'm getting errors that it's not a valid callback. $ cat test.php <? $arrays = array( 'arrEmpty' => array( '','','' ), ); foreach ( $arrays as $key => $array ) { echo $key . "\n"; echo array_reduce( $array, "empty" ); var_dump( array_map("empty", $array) ); echo "\n\n"; } $ php test.php arrEmpty Warning: array_reduce(): The second argument, 'empty', should be a valid callback in /var/www/authentication_class/test.php on line 12 Warning: array_map(): The first argument, 'empty', should be either NULL or a valid callback in /var/www/authentication_class/test.php on line 13 NULL Shouldn't this work? Long story: I'm trying to be (too?) clever and checking that all array values are not empty strings.

  • StreamWriter stops writing when file is opened from web link

    - by fearofawhackplanet
    Following on from my previous question... The following code creates log files on a web server: private void LogMessage(Message msg) { using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt")) { sw.WriteLine(msg.ToString()); } } The log files are linked to from an admin page on the web site: foreach (FileInfo file in logDir.GetFiles()) { Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>"); } I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.

    So far I have this code run when the X button is clicked, but I'm not sure if this is the correct way to terminate threads on a form on exit. Type t = this.GetType(); foreach (PropertyInfo pi in t.GetProperties()) { if (pi.GetType() == typeof(Thread)) { MethodInfo mi = pi.GetType().GetMethod("Abort"); mi.Invoke(null, new object[] {}); } } I keep getting this error: "An attempt has been made to free an RCW that is in use.

  • C# method generic params parameter bug?

    - by Mike M
    Hey, I appears to me as though there is a bug/inconsistency in the C# compiler. This works fine (first method gets called): public void SomeMethod(string message, object data); public void SomeMethod(string message, params object[] data); // .... SomeMethod("woohoo", item); Yet this causes "The call is ambiguous between the following methods" error: public void SomeMethod(string message, T data); public void SomeMethod(string message, params T[] data); // .... SomeMethod("woohoo", (T)item); I could just use the dump the first method entirely, but since this is a very performance sensitive library and the first method will be used about 75% of the time, I would rather not always wrap things in an array and instantiate an iterator to go over a foreach if there is only one item. Splitting into different named methods would be messy at best IMO. Thoughts?

  • Delete from array help

    - by Camran
    I have a cookie which stores info in an array. This is for a classifieds website, and whenever users delete their 'ads' the cookie must also be removed of the ad which was deleted. So I have this: if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; $ad_arr = unserialize($_COOKIE['watched_ads']); foreach($ad_arr as $val){ if($val==$id){ // $id is something like "bmw_m3_10141912" unset($val); setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } } This doesn't work... any idea why? I think its a problem with the unset part... Also, keep in mind if there is only one value inside the array, what will happen then? Thanks

  • Exception when programmatically copying content type

    - by BeraCim
    Hi all: I'm getting exceptions when copying content type from one web to another: foreach (SPContentType destinationWebCt in destinationWeb.ContentTypes) { destinationWeb.ContentTypes.Add(existingWebCt); destinationWeb.Update(); } existingWebCt is the content type from another web e.g. /Site/Web. destinationWeb is the web that I wish to copy the content type to e.g. /Site/DestinationWeb. I got the SPException that says something like content type can not be added outside of its scope. Then I decided to replace all "ContentTypes" to "AvailableContentTypes", but then I got the SPException saying this collcetion could not be modified. So how can I copy a content type to another web? Thanks.

  • Cross-Platform Camera API

    - by Karim
    Hi, I'm now building a video transforming filter that have to transform video frames in real-time. One of the key requirements of the filter is to have high performance to minimize the number of dropped frames during the transform. Another requirement that is of lower priority but also nice to have is to make it cross-platform (both PC's and Mobile devices). The application is built in C++. Now my question is: is there any API that is more portable and has a similar or better performance characteristics than DirectShow? as DirectShow's portability is only limited to Windows-based devices (PCs and Windows Mobile&CE platforms). Also I've notices that for example using HTC's custom camera API has far better performance than what DirectShow offers. If you want to check this, try to build a filter in DirectShow that will multiply each color by 2 and render that in real-time from camera on the screen. Then do the same with HTC's API. There is almost 4-5x performance boost with vendor's specific API. So it'd be very nice if the library used the device-specific implementation of the driver, as performance is critical when doing this transforms on a mobile device (which is about ~500 MHz).

  • How to get encoding from MAPI message with PR_BODY_A tag (windows mobile)?

    - by SadSido
    Hi, everyone! I am developing a program, that handles incoming e-mail and sms through windows-mobile MAPI. The code basically looks like that: ulBodyProp = PR_BODY_A; hr = piMessage->OpenProperty(ulBodyProp, NULL, STGM_READ, 0, (LPUNKNOWN*)&piStream); if (hr == S_OK) { // ... get body size in bytes ... STATSTG statstg; piStream->Stat(&statstg, 0); ULONG cbBody = statstg.cbSize.LowPart; // ... allocate memory for the buffer ... BYTE* pszBodyInBytes = NULL; boost::scoped_array<BYTE> szBodyInBytesPtr(pszBodyInBytes = new BYTE[cbBody+2]); // ... read body into the pszBodyInBytes ... } That works and I have a message body. The problem is that this body is multibyte encoded and I need to return a Unicode string. I guess, I have to use ::MultiByteToWideChar() function, but how can I guess, what codepage should I apply? Using CP_UTF8 is naive, because it can simply be not in UTF8. Using CP_ACP works, well, sometimes, but sometimes does not. So, my question is: how can I retrieve the information about message codepage. Does MAPI provide any functions for it? Or is there a way to decode multibyte string, other than MultiByteToWideChar()? Thanks!

  • Jquery background overlay/alert without .onclick event - php responder?

    - by Philip
    Hi guys, I have no experience with jquery or javascript for that matter. I am trying to implement this technique to respond to users for errors or messages in general. lights-out-dimmingcovering-background-content-with-jquery This method uses the onclick event and that's not what im after, I have tried to replace .onclick with .load but that doesn't seem to work. I'm after a quick fix as I really don't have the time to learn jquery or its event handlers. The goal is to catch any errors or message's and once these are called the alert box is called without any further actions such as .onclick. How my code would look: {PHP} $forms = new forms(); if(count($forms->showErrors) > 0 // or == true) { foreach($forms->showErrors as $error) { print('<p class="alert">'.htmlspecialchars($error, ENT_QUOTES).'</p>'); } }
