  • VB6 App + .Net component working as compiled app but not in VB6 IDE

    - by Craig Johnston
    I have a VB6 App that uses a .Net component (via a .tlb reference in the VB6 app) which is working fine when executed as a compiled app, but it produces an error from the VB6 IDE a certain point when it is trying to use the .NET component. I should note that the error occurs when the .NET component is meant to be invoking a third party reporting component. What could the problem be? Could the VB6 IDE be looking in a different location for certain DLLs? The .tlb is in the same location as the application executable so I don't why there should be a problem. I need to have the application running in the IDE in order to debug and step through the code.

  • Eclipse hangs while opening workspace after upgrading to GWT 2.0/Google app engine 1.2.8

    - by Domchi
    After upgrading to the newest GWT/Google app engine I have problems opening my workspace in Eclipse. On startup, Eclipse hangs almost immediately and needs to be closed. This happens only in the workspace where I use GWT with app engine, and I weren't able to consistently reproduce it - sometimes it starts normally, and sometimes I need to kill the proces and restart it. There is nothing in Eclipse error log. Eclipse version is Galileo, running on Windows 7 RC. Anyone else had similar problems? I googled but Google is not my friend today. EDIT: Still happens after upgrading to GWT 2.0.1.

  • Interface Photoshop size for iPhone app

    - by Sorin M
    Hello, I am building an iPhone app interface and I know the dpi has to be 163, but when it comes to the size of the file, I was looking through all the recommendations and found 2 different answers... Does anyone know what size should i set the Photoshop file at? The answers I have so far are: "The screen on the iPhone is 480×320, minus the 20-pixel status bar (making a 460×320 working screen size). The screen shots on the App Store should not include the status bar." "400 x 320 or 960 x 640 (iPhone 4) You must also consider the landscape mode (320 x 400 and 640 x 960)" I would really appreciate the answer. Thanks!

  • MVC in a Google App Engine Java world

    - by thatismatt
    I'm coming to Java from C# & ASP.NET MVC, I'd love to find an equivalent in the Java world that I could use on the Google App Engine. I've already started to have a play with FreeMarker and even made the first steps towards writing a very simple framework. Ideally I wouldn't have to do all the hard work though, someone must have done this already! So my question is - what frameworks are there out there that would be familiar for me coming from ASP.NET MVC and I could use them on Google App Engine for Java. The key things I'd want are: Simple Routing - /products/view/1 gets mapped to the view action of the products controller with the productid of 1 Template Engine - some way of easily passing 'ViewData' to the view, and from the view easily accessing it, ideally I'd love to avoid anything that is too XMLy (thus why I like FreeMarker).

  • What alternatives are there to Google App Engine?

    - by Chris Marasti-Georg
    What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

  • change the class loading order google app engine java

    - by Shekhar
    I am trying to create an application on google app engine using struts2. Struts2 internally uses freemarker .One of the Freemarker framework classes suppose X internally uses a class javax.swing.Treenode which is not in google app engine jre white list. Now in order to run my application i created a new class X in the same package structure as it was in freemarker framework and copied the class to WEB-INF classes.Then When i run my application it run fine. The problem is that i want to take out the class X from my application sourcecode and move it to newly created jar and place it in WEB-INF/lib folder. So that i can reuse the code in multiple project and my code remains clean of the freemarker code. But when i run the application it picks the old class X from the original freemarker framework.As a result i get ClassNotFoundException. Can anyone provide any help such that i can change the ClassLoading order such that my jar containing X class loads first.

  • Google App Engine: Unit testing concurrent access to memcache

    - by Phuong Nguyen de ManCity fan
    Would you guys show me a way to simulating concurrent access to memcache on Google App Engine? I'm trying with LocalServiceTestHelpers and threads but don't have any luck. Every time I try to access Memcache within a thread, then I get this error: ApiProxy$CallNotFoundException: The API package 'memcache' or call 'Increment()' was not found I guess that the testing library of GAE SDK tried to mimic the real environment and thus setup the environment for only one thread (the thread that running the test) which cannot be seen by other thread. Here is a piece of code that can reproduce the problem package org.seamoo.cache.memcacheImpl; import org.testng.Assert; import org.testng.annotations.AfterMethod; import org.testng.annotations.BeforeMethod; import org.testng.annotations.Test; import com.google.appengine.api.memcache.MemcacheService; import com.google.appengine.api.memcache.MemcacheServiceFactory; import com.google.appengine.tools.development.testing.LocalMemcacheServiceTestConfig; import com.google.appengine.tools.development.testing.LocalServiceTestHelper; public class MemcacheTest { LocalServiceTestHelper helper; public MemcacheTest() { LocalMemcacheServiceTestConfig memcacheConfig = new LocalMemcacheServiceTestConfig(); helper = new LocalServiceTestHelper(memcacheConfig); } /** * */ @BeforeMethod public void setUp() { helper.setUp(); } /** * @see LocalServiceTest#tearDown() */ @AfterMethod public void tearDown() { helper.tearDown(); } @Test public void memcacheConcurrentAccess() throws InterruptedException { final MemcacheService service = MemcacheServiceFactory.getMemcacheService(); Runnable runner = new Runnable() { @Override public void run() { // TODO Auto-generated method stub service.increment("test-key", 1L, 1L); try { Thread.sleep(200L); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } service.increment("test-key", 1L, 1L); } }; Thread t1 = new Thread(runner); Thread t2 = new Thread(runner); t1.start(); t2.start(); while (t1.isAlive()) { Thread.sleep(100L); } Assert.assertEquals((Long) (service.get("test-key")), new Long(4L)); } }

    - by inutan
    Hello there, I have two Services called TemplateService, TemplateReportService (both defined in one WCF Service Library) to be exposed to the client application. And, I am trying to host these services under Windows Service. Can anyone please guide me if App.config in Windows Service will be same as the one in WCF Library? Here is my app.config in WCF Library: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <system.serviceModel> <services> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" ></endpoint> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateService/" /> </baseAddresses> </host> </service> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateReportService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateReportService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateReportService/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ReportingComponentLibrary.TemplateServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> So, the App.config in my Windows Service(Where I am hosting above two services) will be same as above or there are only some particular sections that I need to move.

    I've got a grails 1.1 web app running great in development but when I try and run it in production with an sqlserver database it crashes in a weird way.

  • GAE API to find where the app is running - local machine OR gae cloud

    - by Jayesh
    Hi, I have a Google App engine application that I want to work differently depending upon if it is running in my local dev environment (i.e. with dev_appserver.py) as against running in actual GAE cloud. Currently I use a flag variable that I manually toggle to achieve that. But I am sure one day I will forget to change it and will lead to problem. So I would like to know if there is an API or some other way to figure out where the GAE app is actually running? Thanks.

  • appcfg.py upload_data entity kind problem

    - by Dingo
    Hi, I am developing application on app-engine-path and I would like to upload some data to datastore. For example I have a model models/places.py: class Place(db.Model): name = db.StringProperty() longitude = db.FloatProperty() latitude = db.FloatProperty() If I save this in view, kind() of this entity is "models_place". All is ok, Place.all() in view work fine. But: If I upload some next row using appcfg.py upload_data, the kind() of this entities is Place. loader.py look like this: import datetime, os, sys from google.appengine.ext import db from google.appengine.tools import bulkloader libs_path = os.path.join("/home/martin/myproject/src/") if libs_path not in sys.path: sys.path.insert(0, libs_path) from models import places class AlbumLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'Place', [('name', lambda x: x.decode('utf-8')), ('longitude', float), ('latitude', float), ]) loaders = [AlbumLoader] and command for uploading: python /usr/local/google_appengine/appcfg.py upload_data --config_file=places_loader.py --kind=models_place --filename=data/places.csv --url=http://localhost:8000/remote_api /home/martin/myproject/src/

  • Goolge App Engine authorization with Google Apps Domain

    - by Ron
    I have successfully followed the examples to gain an AuthSub token to authorize my application to have access to the user's Google Calendar. I have added the domain parameter to the method gdata.auth.generate_auth_sub_url so that the application is authenticated against a Google Apps Domain user. The app is then installed in one of our test domains. This is working fine, however, each user in the domain has to go through the authorization process. In other Marketplace Apps that I have tried, this authorization is done once for the whole domain when the app is installed. How is this achieved?

  • Google App Engine and Git best practices

    - by systempuntoout
    I'm developing a small pet project on Google App Engine and i would like to keep code under source control using github; this will allow a friend of mine to checkout and modify the sources. I just have a directory with all sources (call it PetProject) and Google App Engine development server points to that directory. Is it correct to create a repo directly from PetProject directory or is it preferable to create a second directory mirroring the develop PetProject directory? In the latter case, anytime my friend will release something new, i need to pull fetch from Git copying the modified files to the develop PetProject directory. If i decide to keep the repo inside the develop directory, skipping .git on Gae yaml is enough? What are the best practices here?

  • How to parse app.config using ConfigurationManager?

    - by Amokrane
    I was using a certain method for parsing my app.config file. Then I was told that using ConfigurationManager is better and simpler. But the thing is I don't know how to do it with ConfigurationManager. My original code looked like this: XmlNode xmlProvidersNode; XmlNodeList xmlProvidersList; XmlNodeList xmlTaskFactoriesList; XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("app.config"); xmlProvidersNode = xmlDoc.DocumentElement.SelectSingleNode("TaskProviders"); xmlProvidersList = xmlProvidersNode.SelectNodes("TaskProvider"); foreach (XmlNode xmlProviderElement in xmlProvidersList) { if (xmlProviderElement.Attributes.GetNamedItem("Name").Value.Equals(_taskProvider)) { xmlTaskFactoriesList = xmlProviderElement.SelectNodes("TaskTypeFactory"); foreach (XmlNode xmlTaskFactoryElement in xmlTaskFactoriesList) { if (xmlTaskFactoryElement.Attributes.GetNamedItem("TaskType").Value.Equals(_taskType)) { taskTypeFactory = xmlTaskFactoryElement.Attributes.GetNamedItem("Class").Value; } } } } What would be the equivalent using ConfigurationManager? (Because all I can see is how to get keys not nodes..) Thanks

  • Problems with testing in app purchases

    - by sashaeve
    I am trying to test my application with in app purchases. I created features, test user, logged out from iTunes on the iPhone and used developer certificate. Load app from XCode in debug mode. When I click "Buy" button I pass all checks for internet availability, canMakePayments and call SKPayment *payment = [SKPayment paymentWithProductIdentifier:featureId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; But all what I see is a pending view and after some minutes it failed in - (void) failedTransaction: (SKPaymentTransaction *)transaction { if (transaction.error.code != SKErrorPaymentCancelled) { NSLog(@"failedTransaction"); } [[MKStoreManager sharedManager] paymentCanceled]; [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; } Please advice in what direction I should go to figure out the problem and what else I should check. P.S. All related questions on SO were checked with no luck.

  • Mixing static and dynamic endpoints in app.yaml file

    - by Greg
    I'm trying to describe endpoints in my App Engine app and am having difficulty for directory structures that mix static and dynamic content. But my yaml rules are conflicting with one another. Before I change my directory structure, does anyone have a recommendation? The goal is to create a directory that contains both documentation (static html files) and implementations. /api - /v1 - getitdone.py - doc.html - index.html What I think I should be doing with my application yaml... - url: /api/v1/getitdone script: api/v1/getitdone.py - url: /api/ static_files: api/index.html upload: api/index.html - url: /api static_dir: api But this causes the dynamic endpoints to fail. I'm assuming the static_dir reference is breaking it. How can I do this without describing every script and static file reference (I have many more than are listed here)?

  • Is the Windows dev environment worth the cost?

    - by MCS
    I recently made the move from Linux development to Windows development. And as much of a Linux enthusiast that I am, I have to say - C# is a beautiful language, Visual Studio is terrific, and now that I've bought myself a trackball my wrist has stopped hurting from using the mouse so much. But there's one thing I can't get past: the cost. Windows 7, Visual Studio, SQL Server, Expression Blend, ViEmu, Telerik, MSDN - we're talking thousands for each developer on the project! You're definitely getting something for your money - my question is, is it worth it? [Not every developer needs all the aforementioned tools - but have you ever heard of anyone writing C# code without Visual Studio? I've worked on pretty large software projects in Linux without having to pay for any development tool whatsoever.] Now obviously, if you're already a Windows shop, it doesn't pay to retrain all your developers. And if you're looking to develop a Windows desktop app, you just can't do that in Linux. But if you were starting a new web application project and could hire developers who are experts in whatever languages you want, would you still choose Windows as your development platform despite the high cost? And if yes, why?

I have tried using Rome and keep getting the following error (tried googling without success), also the code I am running that generates the error is the demo code (so I get the feeling Rome won't work with GAE) java.lang.NoClassDefFoundError: org/jdom/JDOMException at com.sun.syndication.io.SyndFeedOutput.<init>(SyndFeedOutput.java:44) What I am looking for is recommendations for a simple Java library to create and publish an Atom feed from within Google App Engine.

  • I want to create an Android App that checks a website like Woot

    - by tim
    Im new to android and thought it would be fun to develop an app that goes out and checks woot.com. The idea I came up with is for the app to be a widget that refresh woot.com once a day and displays a picture of the item and price. If the widget is clicked on it would open the browser to woot.com. In theory this seems like it would be easy but Im having trouble figuring out where to begin. Any help would be appreciated. Thanks Tim

  • Artificial Intelligence in online game using Google App Engine

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)
