  • What is the best way to implement a Server-Client connection between an iPad and multiple iPhones?

    - by Infinite
    Based on a college-project I'm trying to realize a relatively simple game (Poker) where an iPad acts as Server and multiple iPod-Touchs connect to it as Clients. Gamekit seems to drop out, since those old ipod-touch-devices don't have bluetooth-support. Are there already some Frameworks out there simplifying the process, or do I have to fall back on TCP-Streaming-Sockets and implement it myself?

  • How to connect two files and use the radio button?

    - by Stupefy101
    I have here a set of form from the index.php to upload a zip file, select an option then perform a converter process. <form action="" method="post" accept-charset="utf-8"> <p class="buttons"><input type="file" value="" name="zip_file"/></p> </form> <form action="index.php" method="post" accept-charset="utf-8" name="form1"> <h3><input type="radio" name="option" value="option1"/> Option1 </h3> <h3><input type="radio" name="option" value="option2"/> Option2 </h3> <h3><input type="radio" name="option" value="option3"/> Option3 </h3> <p class="buttons"><input type="submit" value="Convert"/></p> </form> In the other hand, this is my code for the upload.php that will extract the Zip file. <?php if($_FILES["zip_file"]["name"]) { $filename = $_FILES["zip_file"]["name"]; $source = $_FILES["zip_file"]["tmp_name"]; $type = $_FILES["zip_file"]["type"]; $name = explode(".", $filename); $accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed'); foreach($accepted_types as $mime_type) { if($mime_type == $type) { $okay = true; break; } } $continue = strtolower($name[1]) == 'zip' ? true : false; if(!$continue) { $message = "The file you are trying to upload is not a .zip file. Please try again."; } $target_path = "C:xampp/htdocs/themer/".$filename; // change this to the correct site path if(move_uploaded_file($source, $target_path)) { $zip = new ZipArchive(); $x = $zip->open($target_path); if ($x === true) { $zip->extractTo("C:xampp/htdocs/themer/"); // change this to the correct site path $zip->close(); unlink($target_path); } $message = "Your .zip file was uploaded and unpacked."; } else { $message = "There was a problem with the upload. Please try again."; } } ?> How can i connect both files that will perform the extracting process? And how to include the codes for radio button after submission? Please Help.

  • How can I implement a 'select all' check-box on my CRM 4 custom form?

    - by Gryphoenix
    I am working on a custom CRM form with numerous checkboxes, organized by sections. I would like to implement a 'select all' feature to the form and am trying to understand how to format the JavaScript. My research thus far has pointed me to the possibility of using a FOR statement to iterate through all of the elements in the section I want to process, setting their values accordingly, but am unsure of which document.getElements ... method to utilize.

  • How do you debug MySQL stored procedures?

    - by Cory House
    My current process for debugging stored procedures is very simple. I create a table called "debug" where I insert variable values from the stored procedure as it runs.

  • Detecting if a file is binary or plain text?

    - by dr. evil
    How can I detect if a file is binary or a plain text? Basically my .NET app is processing batch files and extracting data however I don't want to process binary files. As a solution I'm thinking about analysing first X bytes of the file and if there are more unprintable characters than printable characters it should be binary. Is this the right way to do it? Is there nay better implementation for this task?

    I am in the process of setting up a batch script to do a specified action if the script was run on a weekday, and an alternate action if run on the weekend.

Can someone please answer both if it is possible, and if it is at least a framework of how to implement it. Thanks in advance.

  • pass commands to an running R-Runtime

    - by tiny81
    Hi, is there a way to pass commands (from a shell) to an all ready running R-runtime/R-Gui, without copy&past. So far I only know how to call R via shell with the -f or -e option, but in both cases a new R-Runtime will process the R-Script or R-Command I passed to it. I rather would like to have an open R-Runtime waiting for commands passed to it (via what ever connection is possible). regrads, Tiny

  • Clickonce appref.ms argument

    - by alan
    I have a clickonce application that is available online or offline. The program takes an argument. When online I pass the argument on the url like so "url?argument" and it works well. Offline i start a process with the startmenu link to the application. My question is, is it possible to pass an argument to my application via this link? I guess I could somehow work out the location of the application file but is there an alternative?

  • Best way to ask confirmation from user before leaving the page

    - by JohnathanKong
    Hey Everyone, I am currently building a registration page where if the user leaves, I want to pop up a CSS box asking him if he is sure or not. I can accomplish this feat using confirm boxes, but the client says that they are too ugly. I've tried using unload and beforeunload, but both cannot stop the page from being redirected. Using those to events, I return false, so maybe there's a way to cancel other than returning false? Another solution that I've had was redirecting them to another page that has my popup, but the problem with that is that if they do want to leave the page, and it wasn't a mistake, they lose the page they were originally trying to go to. If I was a user, that would irritate me. The last solution was real popup window. The only thing I don't like about that is that the main winow will have their destination page while the pop will have my page. In my opinion it looks disjoint. On top of that, I'd be worried about popup blockers. Just to add to everyones comments. I understand that it is irritating to prevent users from exiting the page, and in my opinion it should not be done. Right now I am using a confirm box at this point. What happens is that it's not actually "preventing" the user from leaving, what the client actually wants to do is make a suggestion if the user is having doubts about registering. If the user is halfway through the registraiton process and leaves for some reason, the client wants to offer the user a free coupon to a seminar (this client is selling seminars) to hopefully persuade the user to register. The client is under the impression that since the user is already on the form, he is thinking of registering, and therefore maybe a seminar of what he is registering for would be the final push to get the user to register. Ideally I don't have to prevent the user from leaving, what would be just as good, and in my opinion better is if I can pause the unload process. Maybe a sleep command? I don't really have to keep the user on the page because either way they will be leaving to go to a different page. Also, as people have stated, this is a terriable title, so if someone knows a better one, I'd really appreciate it if they could change the title to something no so spammer inviting.

  • Multiple repositories, single setup

    - by graham.reeds
    If I use multiple repositories, all located under a single root folder, how can I set it up so that they will use a single master svnconf/passwd file for setup but still allow me to customize each if the need arises? This is on windows but I guess the process would be similar on other systems. Update: I am using svnserve as a service.

  • How to change windows exe file's icon in linux without wine?

    I know I can use ResHacker to change a resource from windows and I know I can use ResourceUpdate function to do the same problematically (again in windows). My problem is that I have to update the icon of a windows exe file in linux, without using wine. (the reason for not using wine is that this process should run on an automation server that change the files and sign them). I don't know even where to start from.

  • carry flag and subtraction issue!

    - by Zia ur Rahman
    If a large number is subtracted from a smaller number then borrow is needed. The carry flag plays the role of borrow during the subtraction operation. Now suppose we want to subtract 56 from 66, obviously the borrow is needed and carry flag will be set. Now how this subtraction is performed to get the result -10, how computer will distinguish that the result is going to be a negative number. Please explain the process.
