  • How to check if datetime is older than 20 seconds.

    - by Jelle
    Hello! This is my first time here so I hope I post this question at the right place. :) I need to build flood control for my script but I'm not good at all this datetime to time conversions with UTC and stuff. I hope you can help me out. I'm using the Google App Engine with Python. I've got a datetimeproperty at the DataStore database which should be checked if it's older than 20 seconds, then proceed. Could anybody help me out? So in semi-psuedo: q = db.GqlQuery("SELECT * FROM Kudo WHERE fromuser = :1", user) lastplus = q.get() if lastplus.date is older than 20 seconds: print"Go!"

  • Unmarshalling collections in JaxB

    - by Stas
    Hi, suppose I have this class: public class A { private HashMap<String, B> map; @XmlElement private void setB(ArrayList<B> col) { ... } private ArrayList<B> getB() { ... } } When trying to unmarshall an xml document to this class using JaxB I notice that instead of calling the setB() method and sending me the list of B instances JaxB actually calls the getB() and adds the B instances to the returned list. Why? The reason I want the setter to be called is that the list is actually just a temporary storage from which I want to build the map field, so I thought to do it in the setter. Thanks.

  • Design of Business Layer

    - by Adil Mughal
    Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.

  • Is wordpress a good platform for webapp development?

    - by darlinton
    I am planning a webapp to control bank paying orders. In a quick review, the user goes online and creates a payment order. This order goes to other people that pays it and register the payment on the system. The system keeps track of all the payments, keeping the account balance up-to-date. The system needs a login system, bank integration, and to support at some point thousands of clients. We can find articles on the web about the benefits of using wordpress platform to build webapps. However, I could not find discussion with counterarguments to user wordpress. As the platform the most important choice in webapp project, I would to know more about the pitfalls and harms for choosing wordpress. The question is: What are the benefits and harms for choosing wordpress as a development platform for a webapp that need to be integrated with other system (backend systems) and to handle thousands of users (does it scale up?)?

  • Find Microsoft SDK (psapi.lib) with Cmake and or qmake

    - by La Chamelle
    Hello, i have an application where is use Qt 4.6 and Microsoft SDKs (the Psapi.Lib). I use cmake or qmake to build. For qmake and cmake i specify in hard the path of the Psapi.lib. qmake : win32 { LIBS += "C:\Program Files\Microsoft SDKs\Windows\v7.0A\Lib\Psapi.Lib" } cmake : SET(PSAPI "C:/Program Files/Microsoft SDKs/Windows/v7.0A/Lib/Psapi.Lib") But i want to avoid the hard path, is there is any way to search the SDK lib ? For linux, there is no problem to search : qmake : unix { CONFIG += link_pkgconfig PKGCONFIG += xmu } cmake : IF(UNIX) INCLUDE(FindPkgConfig) PKG_CHECK_MODULES(XMU xmu REQUIRED) INCLUDE_DIRECTORIES(${XMU_INCLUDE_DIR}) LINK_DIRECTORIES(${XMU_LIBRARY_DIRS}) ENDIF() It's possible to make the same ? Thanks you.

  • Any way to get TStringList.CommaText to not escape commas with quotes?

    - by Mason Wheeler
    I'm doing some work with code generation, and one of the things I need to do is create a function call where one of the parameters is a function call, like so: result := Func1(x, y, Func2(a, b, c)); TStringList.CommaText is very useful for generating the parameter lists, but when I traverse the tree to build the outer function call, what I end up with looks like this: result := Func1(x, y, "Func2(a, b, c)"); It's quoting the third argument because it contains commas, and that produced invalid code. But I can't do something simplistic like StringReplace all double quotes with empty strings, because it's quite possible that a function argument could be a string with double quotes inside. Is there any way to make it just not escape the lines that contain commas?

  • How to allow users to customize a DAL

    - by rsteckly
    Hi, I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

  • Using code in both Actionscript3 and Javascript

    - by Ian
    Here's an interesting architectural query. I have a piece of code that needs to run on the server (under Node.js) and on the client (in a Flash 10 app written with Actionscript 3). The code is mostly fairly intricate object manipulation, it doesn't make any API calls, and works fine in both contexts. So far the project is just a demo, so I've been happy to copy and paste the code into both places. But it might be quite interesting to move forward with this. So how would you do it? I assume there is no easy way to get the Flash SDK (has to build without an IDE) to read and do something useful with a .js file. My only thought is that I could write a code-generator that takes the .js file and places it in an ActionScript wrapper. Are there any obvious approaches that I've missed? Just to pre-empt an obvious answer, I know about cross-platform languages like HaXe.

  • Cannot load JRubyEngine because org.apache.bsf.util.BSFEngineImpl not found

    - by Ceilingfish
    Hi, I'm trying to use JRuby in a custom application, and I don't seem to be able to load the JRubyEngine object. My class looks like functionally similar to this: public class ScriptEngine { private static ScriptEngine engine = new JRubyEngine(); public void run(final String script, final Map<String,Object> input) { final Bindings context = engine.createBindings(); context.putAll(input); try { engine.eval(script,context); } catch (ScriptException e) { log.error("Failed to execute script: "+getScript(),e); } } } However this fails at compilation with the complaint: [javac] Compiling 486 source files to /workspace/myProject/build/src [javac] /workspace/myProject/src/net/ceilingfish/ScriptEngine.java:31: cannot access org.apache.bsf.util.BSFEngineImpl [javac] class file for org.apache.bsf.util.BSFEngineImpl not found [javac] private static ScriptEngine engine = new JRubyEngine(); [javac] ^ [javac] 1 error Does anyone have any insights on where I can get this class from? Or if there is a better way to be instantiating a JRubyEngine object.

  • Problem wit MDAC when trying to compile in VS2008 using x64 bit target platform

    - by grobartn
    I am trying to compile an 32 bit application. I am aware of problems with it but that is why its being compiled on 64 bit version. I am hanging at this problem. Application uses lots of sql stuff. In sqltypes.h file: (provided by MDAC) #ifdef _WIN64 typedef INT64 SQLLEN; typedef UINT64 SQLULEN; typedef UINT64 SQLSETPOSIROW; #else For some reason when its compiled on 32 bit platform it works great But when I try building it on 64 it goes berserk. Error 61 error C2146: syntax error : missing ';' before identifier 'SQLLEN' ..\external\microsoft sdk\include\sqltypes.h 50 It does not recognize INT64, UINT64. Is there something I need to enable so it will work under 64 build process? Missing some #include or #define? Any help would be great Thanks

  • jsTree: Prevent before and after TYPE, only use inside

    - by Nic Hubbard
    I am using jsTree which is very nice. When dragging and dropping, I don't really care for the before and after types, I only want to use inside. Meaning, I am only concerned about that parent that a child is dropped into, rather than where the order is with other elements INSIDE the parent. So, I wanted to build my callback, so it always refers to the parent node that it is inside. But, it is not fool proof, yet. onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { if (TYPE == 'inside') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).attr('rel')+' '+TYPE); } else if (TYPE == 'after') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).parent().parent('li').attr('rel')+' '+TYPE); } }, Does anyone have suggestions, how I can change my callback, so that the REF_NODE is always the parent that the NODE is moved into? Rather than a sibling of, which is a child of the parent?

  • how to install mysqlDb for MySQL and Python ON WINDOWS

    I AM A NET DEVELOPER TRY TO INSTALL MYSQLDB FOR PYTHON I KEEP HAVING THIS ERROR MESSAGE raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb I AM FOLLOWING THIS INSTRUCTION FROM THIS SITE <"http://sourceforge.net/project/shownotes.php?release_id=303257" I DO NOT UNDERSTAND THESE LINES Windows ....... C:... python setup.py install C:... python setup.py bdist_wininst The latter example should build a Windows installer package, if you have the correct tools. In any event, you must have a C compiler. Additionally, you have to set an environment variable (mysqlroot) which is the path to your MySQL installation. In theory, it would be possible to get this information out of the registry, but like I said, I don't do Windows, but I'll accept a patch that does this. I HAVE BEEN SEARCHING FOR ANSWER ALL DAY PLEASE DO ANYBODY REALLY KNOW HOW TO DO THIS OR AT LEAST POINT ME IN THE RIGHT DIRECTION???? THANKS and what is the c compiler for???????

  • Free hosting service for private and public git repositories

    - by Alexander
    Hi, does anyone know a free service for hosting private and public git repositories? There are a lot of services like for example the well known github. Most of them only allow hosting of public repositories. I want to host one or more of my private programming projects using git, but not all of them should be public (at least not for now). I also found the free service GitFarm which is build using the Google App Engine technology, but i couldn't find any information how it works (don't know what "built on Google App Engine technology" means) or if there are any other limitations. Also it seams like there is no web front-end available. An integrated web front-end, bug tracker and stuff like this would also be a big plus!

  • regex partial match for several different groups

    - by koral
    I need regexp to match string build from several groups (A is any letter, 9 is any digit): group 1 regex [A-Z]{1,2}[0-9]? A A9 AA9 group 2 regex [A-Z]{1,3}[0-9]? A AA AAA AAA9 group 3 regex [A-Z]{2,3}[0-9]?[A-Z]? AAA AA9 AA9A group 4 regex [0-9]{1,2}[A-Z]{1,2}[0-9]? 9A 9AA 9A9 99A9 Not each group must be present but there must be all in correct order - I mean (digit is group number): 1 12 123 1234 So if there is present group 3 there must me all preceding groups present also. As there are four groups (can be more), so alternative like ^[A-Z]{1,2}[0-9]{1}|[A-Z]{1,2}[0-9]{1}\s{1}[A-Z]{1}[0-9]?$ is not the best option as it would be complicated and difficult to maintain. Is there any solution with groups or something? The order of groups is important.

  • (iPhone SDK) How to link instance variables to a specific UILabel

    - by Timbo
    I'm using the iPhone SDK to build a simple application. I've created a brand new class which has a single variable. I need to make 5 instances of that class, which I have no trouble doing. I can create those instances and also set the variables without issue. What i do need to know is this: How do I link each of the 5 different instances of the variable to different and specific UILabels? Would I be better to create a method that dynamically creates and positions the labels? Thanks for your help in advance, I'm now to this iphone programming thing. I'm serious about learning fast though so I have posted a bounty on this question here : http://www.askearn.com/Responses.aspx?QuestionID=6542613f-7be8-4bb3-a950-aac218d47711

  • FluentNHibernate 1.1 / Castle 1.1 dependency

    - by Innogetics
    I would like to upgrade my FluentNHibernate to version 1.1, but I found out it uses Castle.Core 1.1. I use Castle.Windsor 1.2 in my app which works with Castle.Core 1.2. I now need to find a version of Castle.Windsor that uses this earlier version of Castle.Core, but I can't find it anywhere. What do you recommend I should do? Wait for a version of FluentNHibernate that uses the latest Castle.Core? OR build FluentNHibernate 1.1 from source using the latest Castle.Core? OR downgrade my Castle.Windsor version?

  • Copying (or recovering) a .PFX password to another machine?

    - by Adam Robinson
    First things first, I'm aware of all of the finger-wagging potential that this question provides. However, I'm attempting to help out a friend with a project so I haven't been part of the decision making process thus far. I'm attempting to set up a new development machine, but one of the projects is signed with a .PFX key that's password protected and the original developer does not remember the password. The current development machine can open and build the project just fine, so I'm wondering if there is any way either to copy or to recover the saved password that Visual Studio is using on the original box so that the file can be used on the new box. Signing with a new file is obviously an option, but one that we'd prefer to avoid. Does anyone know of a way either to recover or copy the credentials for this file to a new machine?

  • How can I create a MethodInfo from an Action delegate

    - by Michael Meadows
    I am trying to develop an NUnit addin that dynamically adds test methods to a suite from an object that contains a list of Action delegates. The problem is that NUnit appears to be leaning heavily on reflection to get the job done. Consequently, it looks like there's no simple way to add my Actions directly to the suite. I must, instead, add MethodInfo objects. This would normally work, but the Action delegates are anonymous, so I would have to build the types and methods to accomplish this. I need to find an easier way to do this, without resorting to using Emit. Does anyone know how to easily create MethodInfo instances from Action delegates?

  • How do I create SEO-Friendly urls in ASP.Net-MVC

    I'm getting myself acquainted with ASP.Net-MVC, and I was trying to accomplish some common tasks I've accomplished in the past with webforms and other functionality. On of the most common tasks I need to do is create SEO-friendly urls, which in the past has meant doing some url rewriting to build the querystring into the directory path. for example: www.somesite.com/productid/1234/widget rather than: www.somesite.com?productid=1234&name=widget What method do I use to accomplish this in ASP.Net-MVC? I've search around, and all I've found is this, which either I'm not understanding properly, or doesn't really answer my question: http://stackoverflow.com/questions/734583/seo-urls-with-asp-net-mvc

  • Mootools not loading fast enough IE6

    - by Tom
    Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom
