  • How do I convert a single char in string to an int

    - by Guest
    Keep in mind, if you choose to answer the question, I am a beginner in the field of programming and may need a bit more explanation than others as to how the solutions work. Thank you for your help. My problem is that I am trying to do computations with parts of a string (consisting only of numbers), but I do not know how to convert an individual char to an int. The string is named "message". for (int place = 0; place < message.size(); place++) { if (secondPlace == 0) { cout << (message[place]) * 100 << endl; } } Thank you.

  • Display loading while webservice is running

    - by poseid
    On the initial request to a page, I trigger a webservice and want to display a loading message. When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?

  • How do you handle options that can't be used together with OptionParser?

    - by Joel
    My Python script (for todo lists) is started from the command line like this: todo [options] <command> [command-options] Some options can not be used together, for example todo add --pos=3 --end "Ask Stackoverflow" would specify both the third position and the end of the list. Likewise todo list --brief --informative would confuse my program about being brief or informative. Since I want to have quite a powerful option control, cases like these will be a bunch, and new ones will surely arise in the future. If a users passes a bad combination of options, I want to give an informative message, preferably along with the usage help provided by optparse. Currently I handle this with an if-else statement that I find really ugly and poor. My dream is to have something like this in my code: parser.set_not_allowed(combination=["--pos", "--end"], message="--pos and --end can not be used together") and the OptionParser would use this when parsing the options. Since this doesn't exist as far as I know, I ask the SO community: How do you handle this?

  • How to modify partial, depending on controller it's viewed from?

    - by user284194
    I'm using a partial from my "messages" controller in my "tags" controller. The portion in question looks like this: <% unless message.tag_list.nil? || message.tag_list.empty? %> <% message.tags.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> <% end %> Is there a way to hide this portion of the partial only when it is viewed from the "tags" controller?

  • How to implement event notification mechanism in AIR

    - by nxhoaf
    Do you know how to implement event notification mechanism in AIR ? For simplicity, consider an example: I want to build two applications: "television" and "remote". Among them, television is implemented using AIR. For the "television" I want to use my remote to send message to the television. How must I do to implement "television" in such way that, it runs in waiting mode and whenever it receives a message from "remote", it will process the message and make a suitable action (i.e. change channel, increase volume...). Thank you in advance.

  • Unwanted automated creation of new instances of an activity class

    - by Marko
    I have an activity (called Sender) with the most basic UI, only a button that sends a message when clicked. In the onClickListener I only call this method: private void sendSMS(String msg) { PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, Sender.class), 0); PendingIntent pi = PendingIntent.getActivity(this, 0, myIntent, 0); SmsManager sms = SmsManager.getDefault(); sms.sendTextMessage("1477", null, msg, pi, null); } This works ok, the message is sent but every time a message is sent a new instance of Sender is started on top of the other. If I call sendSMS method three times, three new instances are started. I'm quite new to android so I need some help with this, I only want the same Sender to be on all the time

  • Running Javascript in PHP

    - by Zero
    I'm loading an external .php file using: <script type="text/javascript" src="myfile.js.php"></script> Within the external myfile.js.php file, I'm using: <?php header('content-type: text/javascript'); $message = "Test message"; ?> document.write('<?php echo $message; ?>'); Everything works fine until I change the name of myfile.js.php to just myfile.php Why does it stop working if I remove the .js part from the file name? I'm serving the file as text/javascript, plus shouldn't the .js part be ignored since .php is the actual file extension? Does anyone know why? Thanks!

  • how to create resources without VS C++ 2008 creating MFC files

    - by numerical25
    I am creating a WIN32 application and I want most of all my application events to be made through the message queue. But everytime I create a dialog box or any resource like that. The IDE auto generates code that I don't necessarily need. I believe it's MFC code not sure. here it is. // dlgChangeDevice.cpp : implementation file // #include "stdafx.h" #include "ZFXD3D.h" #include "dlgChangeDevice.h" // dlgChangeDevice dialog IMPLEMENT_DYNAMIC(dlgChangeDevice, CDialog) dlgChangeDevice::dlgChangeDevice(CWnd* pParent /*=NULL*/) : CDialog(dlgChangeDevice::IDD, pParent) { } dlgChangeDevice::~dlgChangeDevice() { } void dlgChangeDevice::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(dlgChangeDevice, CDialog) ON_CBN_SELCHANGE(IDC_COMBO5, &dlgChangeDevice::OnCbnSelchangeCombo5) END_MESSAGE_MAP() // dlgChangeDevice message handlers void dlgChangeDevice::OnCbnSelchangeCombo5() { // TODO: Add your control notification handler code here } Not sure what it is but I don't need it. I want to retrieve all my code through the dialog message queue. So what should I do ?? Just disregard it and delete it. Will a hurt anything by doing so ??

    Hey guys I have one command that works on my remote linux server but not my windows (WAMP package) local server.

  • HTML, jQuery Suggestion for a List

    - by AnApprentice
    Hello, I'm creating an app that will have a list of messages, each message can be either read or unread. Think GMAIL (though I'm not trying to rebuild that)... My question is when I output all these messages, I need to list if the message is read or unread, I also need to provide the ability to change the message status, from read to unread. That being said, how do you suggest I stored this? A checkbox, a hidden input value? Any thoughts? Thanks

  • Best way to attach row from datagrid to EF.

    - by AKoran
    Using MVVM and EF...I have a datagrid binding to a View Model (using ObservableCollection). The view model has a save command which simply calls the SaveChanges command of the Data Context. However, when a user adds a new row to the datagrid, the new entity is detached. Is there any easy way to automatically attach it when it gets created. Currently, I'm having to do this in the Save command of my View Model and it seems a bit clunky: foreach (var dataItem in _DataList) // where _DataList is the ObservableCollection { if (dataItem.EntityState == EntityState.Detached) { _DataContext.AddToTestTables(dataItem); } } _DataContext.SaveChanges();

  • gprof and execl() - is it possible?

    - by Chris
    Background: I have a game (an old-school-esque MUD) which I've been attempting to profile with gprof. The documentation of gprof (on Linux 2.6) states that The profiled program must call "exit"(2) or return normally for the profiling information to be saved in the gmon.out file. Now, if I kill the server with the shutdown command, the application "returns normally" (i.e., main() returns) and I get a gmon.out to analyze. However, it's far more common to reboot the server. The reboot command does the following: Writes usernames and socket FD numbers to disc. Makes a call to execl(). The new process looks for the stored data, picks up the FDs, and moves on. I see the following error on the command line, as the whole process fails: Profiling timer expired ./program Question: Is it possible to get a gmon.out file from the execl()-calling process? Perhaps some environmental parameter to execl(), or else perhaps a different, gprof-friendly, system call to achieve the same effect (beginning a new process while preserving file descriptors)?

  • Storing task state between multiple django processes

    - by user366148
    I am building a logging-bridge between rabbitmq messages and Django application to store background task state in the database for further investigation/review, also to make it possible to re-publish tasks via the Django admin interface. I guess it's nothing fancy, just a standard Producer-Consumer pattern. Web application publishes to message queue and inserts initial task state into the database Consumer, which is a separate python process, handles the message and updates the task state depending on task output The problem is, some tasks are missing in the db and therefore never executed. I suspect it's because Consumer receives the message earlier than db commit is performed. So basically, returning from Model.save() doesn't mean the transaction has ended and the whole communication breaks. Is there any way I could fix this? Maybe some kind of post_transaction signal I could use? Thank you in advance.

  • What is the recommended way to split messages in send pipelines?

    - by ToxicAvenger
    I need to split a bizTalk message in the send pipeline. This is easy with disassemblers in receive pipelines, but doesn't work in send pipelines (makes sense). So what is the recommended way to do it? The only easy way to do it is to write the outbound message to file, then reprocess it using a receive pipeline with a disassembler, and then send the generated messages through a outbound pipeline. Honestly, I don't need the additional roundtrip through the message box, but I don't want to create a custom send adapter. Any other suggestions? Any easy way to save messages with multiple parts using the ootb file adapter?

  • Sending OK Response over HTTP to a webpage request

    - by Prashant
    Hi, I am using an SMS Gateway to make my application receive SMSs. For this, the SMS Gateway sends a request to one of the pages in my application with the message as a querystring parameter. eg. http://myapplication/SMSReceiver.aspx?Message=PaulaIsHome. Now after my page gets invoked, I need to send an OK response to the SMS Gateway so that it doesn't keep retrying to send the same message to my application again and again. I cannot figure out how to send the OK response. I am using ASP .Net and C#. Thanks

  • error reporting issues

    - by SunnyOne
    I'm still entangled in error handling problems. After having read and tried lots of different scripts, I still do not have an overall insight on the problem. I made a syntax error on purpose and get the following error message : Parse error: syntax error, unexpected '{' in /home/directory/public_html/mypage.php on line 10 To understand how it work, as a first step, I'd like to remove this message(which I'am able to do) and replace it by a custom one. How can I customize this message ? Thanks a lot.

  • How do I get User.message_set messages to show up for the built in test client?

    - by Conley Owens
    I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

  • Question about regex in linux commands.

    - by smwikipedia
    I ran the following command at linux bash: apt-cache search hex.*(view|edit) My intention was to find any software packages whose name/description contains the pattern 'hex.*(view|edit)'. But among the results I got this: kipi-plugins - image manipulation/handling plugins for KIPI aware programs How could this be in the results list? I didn't see any matching string in this result. Is this a bug of the apt-cache search command? Or do I mis-understand how the regex is used by this command? Many thanks.
