  • MySQL: How to check if a string is a valid DATE, TIME or DATETIME

    - by Svish
    When I try to put a value into a DATE field which is invalid, MySQL seems to use 0000-00-00 instead. Is there a way I can do this "check" without updating a DATE field? And to do it from for example PHP? Like, is there a way I can query the MySQL server and ask "Hey, is this DATE, TIME or DATETIME valid to you?" Or is there maybe an even better way of doing it?

  • How to find the class object of Java generic type?

    - by Samuel Yung
    Assume I have a generic type P which is an Enum, that is <P extends Enum<P>>, and I want to get the Enum value from a string, for example: String foo = "foo"; P fooEnum = Enum.valueOf(P.class, foo); This will get a compile error because P.class is invalid. So what can I do in order to make the above code work?

  • Does a syntax for this exist? In any language?

    - by Michael
    It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

  • How to reference a particular JSON in a function call.

    - by Jane Wilkie
    Hi guys! I have two javascript routines.. the first one declares some JSON and it contains a function that takes two arguments, the first argument being the json object that needs traversing and the second argument is the tab that the rendering is done in. The second routine merely passes the name of the JSON that needs traversing and tab to render in. The code is below.... <script language="JavaScript1.2" type="text/javascript"> var arr = [ {"id":"10", "class":"child-of-9", "useless":"donotneed"}, {"id":"11", "class":"child-of-10", "useless":"donotneed"}]; var arrtwo = [ {"id":"12", "class":"child-of-12", "useless":"donotneed"}, {"id":"13", "class":"child-of-13", "useless":"donotneed"}]; function render_help(json,tab){ var html=''; for(var i=0;i<json.length;i++){ var obj = json[i]; for(var key in obj){ var attrName = key; var attrValue = obj[key]; if (attrName == "id"){ html = html +'<B>'+attrValue+'</B>'+'<BR><BR>'; }else if (attrName == "class"){ html = html + attrValue + '<BR><BR>'; } } } document.getElementById(tab).innerHTML=(html); } </script> <script language="JavaScript1.2" type="text/javascript"> render_help(arr,"helptab"); </script> Various testing and strategically placed alert boxes indicate that the tab parameter is being passed and interpreted correctly. I know this because when I change .... document.getElementById(tab).innerHTML=(html); to document.getElementById(tab).innerHTML=("Howdy"); and it renders "Howdy" just fine. Putting an alert box (alert(json)) in to check the value of json yields.... [object.Object],[object.Object] The JSON object remains elusive. For the purposes of this scripting I need the JSON "arr" to be iterated over. I feel like the answer is fairly obvious so far no luck. Admittedly I am new with Javascript and I am apparently missing something. Does anyone have a clue as to what I'm overlooking here? Happy New Year to you all! Janie

  • Why is .NET Post different from CURL? broken?

    - by ironnailpiercethesky
    I dont understand this. I ran this code below and the result json string was the link is expired (meaning invalid). However the curl code does the exact same thing and works. I either get the expected string with the url or it says i need to wait (for a few seconds to 1 minute). Why? whats the difference between the two? It looks very F%^&*ed up that it is behaving differently (its been causing me HOURS of problems). NOTE: the only cookie required by the site is SID (tested). It holds your session id. The first post activates it and the 2nd command checks the status with the returning json string. Feel free to set the CookieContainer to only use SID if you like. WARNING: you may want to change SID to a different value so other people arent activating it. Your may want to run the 2nd url to ensure the session id is not used and says expired/invalid before you start. additional note: with curl or in your browser if you do the POST command you can stick the sid in .NET cookie container and the 2nd command will work. But doing the first command (the POST data) will not work. This post function i have used for many other sites that require post and so far it has worked. Obviously checking the Method is a big deal and i see it is indeed POST when doing the first command. static void Main(string[] args) { var cookie = new CookieContainer(); PostData("http://uploading.com/files/get/37e36ed8/", "action=second_page&file_id=9134949&code=37e36ed8", cookie); Thread.Sleep(4000); var res = PostData("http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined", null/*this makes it GET*/, cookie); Console.WriteLine(res); /* curl -b "SID=37468830" -A "DUMMY_User_Aggent" -d "action=second_page&file_id=9134949&code=37e36ed8" "http://uploading.com/files/get/37e36ed8/" curl -b "SID=37468830" -A "DUMMY_User_Aggent" "http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined" */ }

  • Sending Data as Instances using Python Sockets

    - by Alice
    I'm working on the networking part of a 2 player game (similar to tetris), and I'm trying to pass the game grid from client to server and vice versa. However, when I tried using send(grid) I get a TypeError: send() argument 1 must be string or read-only buffer, not instance. Is there anyway to circumvent this, or do I have to convert my grid instance into a string and then interpret it from the other side? Thanks in advance!

  • Java slick command line app?

    - by Felix
    Hello Guys, I want to make a slick java commandline app which doesnt include all the nasty "java -jar some.jar arguments" instead, I would have it work just like program -option argument like any other commandline app. I use ubuntu linux, and it would be fine if it included a bit of .sh script or anything. I know I can just create a file with java -jar program.jar and do chmod +x file, afterwards I could run i with ./file, but then how can I pass the arguments to the program ?

  • How to format date from string?

    - by 4thSpace
    I have a string with this value: 2010-05-13 23:17:29 I'd like to format it and am using the following code: NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateStyle = NSDateFormatterMediumStyle; NSDate *formattedDate = [formatter dateFromString:dateString]; [formatter release]; When the debugger reaches the release line, formattedDate shows "invalid CFStringRef" and Cannot access memory at address 0x0 Any ideas what I'm doing wrong?

  • How to find out if a method exists in Obj-C when given an NSString

    - by Justin
    I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.

  • Writing a file shredder in python or ruby?

    - by pmilb21
    In the effort to learn python and/or ruby, I was wondering how a file shredder would be implemented? I would like it to take in a file as an argument and then employ an algorithm to make that file unrecoverable. Would possibly add the support for multiple files or even whole directories later.

  • Check directory for files, retrieve first file

    - by Lowgain
    I'm writing a small ruby daemon that I am hoping will do the following: Check if a specific directory has files (in this case, .yml files) If so, take the first file (numerically sorted preferrably), and parse into a hash Do a 'yield', with this hash as the argument What I have right now is like: loop do get_next_in_queue { |s| THINGS } end def get_next_in_queue queue_dir = Dir[File.dirname(__FILE__)+'/../queue'] info = YAML::load_file(queue_dir[0]) #not sure if this works or not yield info end I'd like to make the yield conditional if possible, so it only happens if a file is actually found. Thanks!
