  • how do I instrospect appengine's datastore models?

    - by python for ever
    in order to dynamically create a form, i have to find the property types of a model's properties at runtime. appengine docs says that Model.properties() will return a dictionary of properties name and their class type. when i use this method in my code, only the name is returned and the classtype value is always empty.

  • What are the scenarios in which case a new class will be loaded?

    - by GK
    That is when you have any jar file attached to you your class path. then as far as i know any class from the jar is loaded for the first time when, when you create any object of that type. or If you are accessing any static member or method of that class. or when you load that by using Class.forName() method. So are there any other ways of loading a class for the first time?

  • IE is doing strange things with JQuery

    - by Syncopated
    So ... The thing is, the code works in FireFox, no problems. But when I open the same page, it gives me the following error: "Undefined is null or not an object." But when I copy the code to a localhost page, it works fine. Also when I clear my cache in IE it works, but only once, if I refresh after that one load, it gives me the same error. Here is the code: <script type="text/javascript" src="datepicker/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> var count3 = 0; var count5 = 0; var count2 = 0; var count4 = 0; $(document).ready(function(){ $('#switch3').click(function(){ $('#switchDiv3').slideToggle(350); if(count3 == 0){ count3 = 1; document.getElementById('switchImage3').src = "images/ArrowDown.png"; return; } else { count3 = 0; document.getElementById('switchImage3').src = "images/ArrowRight.png"; return; } }); ... (this is the code for each item that is generated) </script> And the code that determines the div that should hide: <table width="100%" border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td width="20" align="center" valign="top" style="padding-right: 3px"> <a style="cursor: pointer;" id="switch3"><img width="20" height="20" src="images/ArrowRight.png" id="switchImage3" style="border-style: solid; border-width: 1px; border-color: black;"/></a> </td> <td> <div id="switchDiv3"> <div align="left"> (Contents of the div here) </div> </div> </td> </tr> </table> Any help is appreciated! Thanks in advance

  • Python: Open() using a variable

    - by nuustik
    Good day, I've ran into a problem with opening a file with randomly generated name in Python 2.6. import random random = random.randint(1,10) localfile = file("%s","wb") % random Then I get an error message about the last line TypeError: unsupported operand type(s) for %: 'file' and 'int' I just couldn't figure this out by myself nor with Google, but there has to be a cure for this, I believe. Thanks.

    - by d0pe
    I'm having some difficulties with this problem. The main idea is, I initialized a variable of class type B in class A, class A.h has the variable Z declared as public, like B *Z; In class A.cpp, I initialized it as Z = new B(); Now, I want to access that variable from class C and I'm unable to do so. C.h includes A.h and B.h

  • "SELECT DISTINCT" ignores different cases

    - by powerbar
    Hello, I have the problem, that MSSQL Server 2000 should select some distinct values from a table (the specific column is of the nvarchar type). There are the sometimes the same values, but with different cases, for example (pseudocode): SELECT DISTINCT * FROM ("A", "a", "b", "B") would return A,b But I do want (and do expect) A,a,b,B because they actually are different values. Any idea how to solve this problem? Thanks a lot in advance!

    - by Ivan
    I'm curious about this code snippet: public static class XNAExtensions { /// <summary> /// Write a Point /// </summary> public static void Write(this NetOutgoingMessage message, Point value) { message.Write(value.X); message.Write(value.Y); } // ... }; What does the this keyword mean next to the parameter type? I can't seem to find any information about it anywhere, even in the C# specification.

  • How is <tgmath.h> implemented?

    - by sync
    C doesn't have (to the best of my knowledge) overloading or templates, right? So how can a set of type-agnostic functions with the same name exist in plain ol' C? The usual compile-time trickery would involve a whole bunch of macros, wouldn't it?
