  • Java Socket - how to catch Exception of BufferedReader.readline()

    - by Hasan Tahsin
    I have a Thread (let's say T1) which reads data from socket: public void run() { while (running) { try { BufferedReader reader = new BufferedReader( new InputStreamReader(socket.getInputStream()) ); String input = reader.readLine(); } catch (IOException e) { e.printStackTrace(); } } } Another Thread (lets say T2) try to finish the program in one of its method. Therefore T2 does the following: T1.running = false; socket.close(); Here is this scenario for which i couldn't find a solution: T1 is active and waiting for some input to read i.e. blocking. context switching T2 is active and sets running to false, closes the socket context switching because T1 was blocking and T2 closed the socket, T1 throws an Exception. What i want is to catch this SocketException. i can't put a try/catch(SocketException) in T1.run(). So how can i catch it in T1's running-method? If it's not possible to catch it in T1's running, then how can i catch it elsewhere? PS: "Another question about the Thread Debugging" Normally when i debug the code step by step, i lose the 'active running line' on a context switch. Let's say i'm in line 20 of T1, context switch happens, let's assume the program continues from the 30.line of T2, but the debugger does not go/show to the 30.line of T2, instead the 'active running line' vanishes. So i lose the control over the code. I use Eclipse for Java and Visual Studio for C#. So what is the best way to track the code while debugging on a context switch ?

  • Drupal's profile_save_profile Doesn't Work in hook_cron, When Run by the Server's cron

    - by anschauung
    I have a problem with the following implementation of hook_cron in Drupal 6.1.3. The script below runs exactly as expected: it sends a welcome letter to new members, and updates a hidden field in their profile to designate that the letter has been sent. There are no errors in the letter, all new members are accounted for, etc. The problem is that the last line -- updating the profile -- doesn't seem to work when Drupal cron is invoked by the 'real' cron on the server. When I run cron manually (such as via /admin/reports/status/run-cron) the profile fields get updated as expected. Any suggestions as to what might be causing this? (Note, since someone will suggest it: members join by means outside of Drupal, and are uploaded to Drupal nightly, so Drupal's built-in welcome letters won't work (I think).) <?php function foo_cron() { // Find users who have not received the new member letter, // and send them a welcome email // Get users who have not recd a message, as per the profile value setting $pending_count_sql = "SELECT COUNT(*) FROM {profile_values} v WHERE (v.value = 0) AND (v.fid = 7)"; //fid 7 is the profile field for profile_intro_email_sent if (db_result(db_query($pending_count_sql))) { // Load the message template, since we // know we have users to feed into it. $email_template_file = "/home/foo/public_html/drupal/" . drupal_get_path('module', 'foo') . "/emails/foo-new-member-email-template.txt"; $email_template_data = file_get_contents($email_template_file); fclose($email_template_fh); //We'll just pull the uid, since we have to run user_load anyway $query = "SELECT v.uid FROM {profile_values} v WHERE (v.value = 0) AND (v.fid = 7)"; $result = db_query(($query)); // Loop through the uids, loading profiles so as to access string replacement variables while ($item = db_fetch_object($result)) { $new_member = user_load($item->uid); $translation_key = array( // ... code that generates the string replacement array ... ); // Compose the email component of the message, and send to user $email_text = t($email_template_data, $translation_key); $language = user_preferred_language($new_member); // use member's language preference $params['subject'] = 'New Member Benefits - Welcome to FOO!'; $params['content-type'] = 'text/plain; charset=UTF-8; format=flowed;'; $params['content'] = $email_text; drupal_mail('foo', 'welcome_letter', $new_member->mail, $language, $params, '[email protected]'); // Mark the user's profile to indicate that the message was sent $change = array( // Rebuild all of the profile fields in this category, // since they'll be deleted otherwise 'profile_first_name' => $new_member->profile_first_name, 'profile_last_name' => $new_member->profile_last_name, 'profile_intro_email_sent' => 1); profile_save_profile($change, $new_member, "Membership Data"); } } }

    I have an ActiveRecord::Base class which needs to have a field that is automatically generated when a new instance is made. How should I go about doing this? By defining an initialize function? class Thing < ActiveRecord::Base # 'special' (integer) needs to be set to lowest unused number (above 0) # considering that random rows will be removed via other processes end This is as far as I've got! Any ideas?

  • Get element id on hover (or mouseover)

    - by Peter C
    Still getting to grips with jQuery and I am pleased to have got as far as I have, especially help from the posts in this forum. However, now got to a working function that does what I want, that is to create a radio group that looks like a button. It pulls data via json and loops through creating the radio buttons. I want to get the id of the radio buttons generated so that I can then parse through to the next step of the app but I can't get it to work. function FillDiv(groups, side) { var cnt = 1; var newClass = ''; var newType = ''; if (side == '#ck-button-left') { newClass = 'leftClass'; newType = 'radio' } else { newClass = 'rightClass'; newType = 'checkbox' } $.each(groups, function (index, groups) { $(side) .append( $(document.createElement('label')).attr({ id: cnt + 'lbl' }) ); $('#' + cnt + 'lbl') .append( $(document.createElement('input')).attr({ id: groups.GroupCode, type: newType, name: 'testGroup', class: newClass }) ); $('#' + groups.GroupCode).after ( $(document.createElement('span')).text(groups.GroupName).attr('class', 'leftSpan') ); $('#' + cnt + 'lbl').after($(document.createElement('br'))); cnt = cnt + 1; }); } Looking through various searched, it should work with something like... $('#leftSpan').mouseover(function () { $('#lblOutput').html(this.id); }); or, as I suspect, it is something to do with the nesting of the label/input that I need to reference the parent or child. Any pointers would be appreciated.

  • CSS working in IE, but not FF

    - by cdotlister
    Hi guys, I have a very simple css file for my Asp.Net MVC application. body { font-family: Arial, Helvetica, sans-serif; font-size: x-small; color: #663300; } input { font-family: Arial, Helvetica, sans-serif; font-size: x-small; background-color: #FFFF99; color: #CC6600; border: 1px solid #808000; } .headerRow { background-color: #FFFFCC; border-style: none none dotted none; border-bottom-width: 1px; border-bottom-color: #800000; font-family: Arial, Helvetica, sans-serif; font-size: x-small; font-weight: bold; text-align: left; vertical-align: middle; text-transform: uppercase; } The Body is working well in both... as is the input. However, the headerRow isn't working in FF, yet works well in IE. Here it is, being used: <table width="700" border="0" cellspacing="1" cellpadding="2"> <tr class="headerRow"> <td> Transaction Date </td> <td> Type </td> <td> Category </td> <td> Budget Assignment </td> <td> Cost Center </td> <td align="right"> Amount </td> </tr> The header row just displays as normal body text though...

  • jQuery replacement for Default Button or Link

    - by pyccki
    As everyone knows, that default button doesn't work in FF, only IE. I've tried to put in the tag or in the and it's not working. I've found a js script to fix this issue, but for some reason it's not working for me. This script for a submit button, i need to use it for a LinkButton, which is should be the same. Link: <div id="pnl"> <a id="ctl00_cphMain_lbLogin" title="Click Here to LogIn" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cphMain$lbLogin&quot;, &quot;&quot;, true, &quot;Login1&quot;, &quot;&quot;, false, true))">Log In</a> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName" /> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName1" /> </div> <script> $(document).ready(function() { $("#pnl").keypress(function(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $("a[id$='_lbLogin']").click(); return true; } }); }); I know that i can override original function "*WebForm_FireDefaultButton*" in This post, but i really wanted to get this one to work. Thanx in advance!!!

  • Difference between these two functions that find Palindromes....

    - by Moin
    I wrote a function to check whether a word is palindrome or not but "unexpectedly", that function failed quite badly, here it is: bool isPalindrome (const string& s){ string reverse = ""; string original = s; for (string_sz i = 0; i != original.size(); ++i){ reverse += original.back(); original.pop_back(); } if (reverse == original) return true; else return false; } It gives me "string iterator offset out of range error" when you pass in a string with only one character and returns true even if we pass in an empty string (although I know its because of the intialisation of the reverse variable) and also when you pass in an unassigned string for example: string input; isPalindrome(input); Later, I found a better function which works as you would expect: bool found(const string& s) { bool found = true; for (string::const_iterator i = s.begin(), j = s.end() - 1; i < j; ++i, --j) { if (*i != *j) found = false; } return found; } Unlike the first function, this function correctly fails when you give it an unassigned string variable or an empty string and works for single characters and such... So, good people of stackoverflow please point out to me why the first function is so bad... Thank You.

  • Adding dynamic content with events in jquerymobile

    - by Christian Waidner
    Currently I'm stuck with a problem in jquerymobile: I'm adding items to a list dynamically and use enhanceWithin() in the end (so styling is correct). After this I like to add click-events for each list item but the problem is, that enhanceWithin runs asynchronous and so I always get the error message "cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'" When I delay the event-adding-code it works perfectly. Does anyone have an idea if there is a enhanceWithin.done event or anything else I can use? HTML: ... <div id="shoppinglist">Loading list...</div> ... Javascript: function updateList() { var result = ""; $.each(shoppinglistItems, function (index, item) { result += '<label><input type="checkbox" ' + item.checked + ' id="item_' + item.id + '">' + item.name + '</label>\n'; }); $('#shoppinglist').html(result).enhanceWithin(); // Change-Events an die Checkboxen knoten $('input[id*=item_]').unbind('change').bind('change', function (event) { var itemid = $(this).attr('id'); itemid = (itemid.split('_'))[1]; // Nur die Zahl extrahieren // Passendes Item aus der Liste der Items suchen und checken $.each(shoppinglistItems, function (index, item) { if (item.id == itemid) { item.checked = "checked"; item.timestamp = moment().format("YYYYMMDDHHmmss"); } }); updateList(); }); }
