• Transferring data to (Windows) Mobile Devices

  - by Ritu

  I created an app for Windows Mobile 6.5 and am fairly happy with it. However, if anyone else need to use this app, they will have to transfer an initial file (txt or csv) to the device. For a developer this isn't a problem but is this too much to ask of an end user? Granted, they will want to move (sync) data back to their desktop after the device's data have been updated. So how do other apps solve this problem? Do I need to provide some kind of syncing software?

• how to use use case relations - uml

  - by joao alves

  Heys guys! Im have been study UML and im trying to to design the use case diagram of a problem. Lets supose my app consists in this: Two Requesites: - create teams - create players This is the deal: A user can create a team, and after create a team he can create players for that team(not required). But in this app there are multiple users, and a user can create a team and other user can create players. The only constraint is that to create players must exist alreay a team. I research and i end up a little confuse. If i get the concepts of relations on use case diagrams right, i think i should have the folowwing two use cases: [use case - create team] <-------extends---- [use case - create player] I need opinions,Is this the proper solution? or should i have two not related use cases? Thanks in advance, and im sorry my english.

• Add HttpOnly flag to cookies on the fly with Apache?

  - by Zack

  So I have a java webapp that uses tomcat with an apache proxy layer. I'm looking to make all cookies set from the app have the httpOnly flag. The problem with this is that tomcat is responsible for setting the flag from the application side and its default (in servlet api 2.5) is false. I was hoping I could set this flag for all cookies on the fly using apache. I've been trying different combinations and the closest I have gotten is setting the last cookie passed to httpOnly which is of course wrong: Header append Set-Cookie "; HttpOnly" I have no way of knowing what cookies/values are going to be passed from the app. Is this even possible?

• moving EDMX file System.Data.MetadataException: Unable to load the specified metadata resource.

  - by Dani

  I have a ASP.NET MVC 2 project. I've created edmx file on the class library project that holds the model. now I've created another class library called it shared and moved the edmx file over there. resolved some issues, everything compiles, but it can't find the connection string resource at runtime. I've copied the ConnectionString part of the Web.Config to the main file, the old class library app.config file and the new class library app.config file. Still get this error: System.Data.MetadataException: Unable to load the specified metadata resource. Line 75: public myProjdb() : base("name=myProjdb", "MyProjdb") in the MyProj.Designer.cs file. Any Idea how to resolve this issue ? Is there a better way to store connection string data ?

• Beginner, learning as I go - how to get C#/SQLite db set up and ready for testing?

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• enable hardware virtulization in BIOS

  - by rhon

  I am running a FOXCONN AM2+ M61PMV with an AMD Athlon II X2 240 windows 7 ultimate 64 bit From startup I have hit the del key and the options for enabling the Hardware virtulization are not there. I have checked the Microsoft tool that says I can run virtual and i have checked SecurAble, that says yes. But I have an open case w/microsoft (they've been trying for a week [7 tech support people later]) and they're saying that i need to ensure that the hardware is enabled. Where do I go to see? is there another way besides from the start up? HELP!

• amp is included in url struts tag

  - by lakshmanan

  Hi, In my web application, I use strust2 url tag to pass parameters like id etc., For example, I use a link to delete an entity and I use param to pass the id of the entity to be deleted. And I follow this throughout my web app for adding, editing, deleting an entity. During run time, sometimes, I don't get the params to be stored in my action's bean properties. When I see the link that is generated, I get something like <a href='/projit1/p/discuss/viewDiscussion.action?d=11&amp;amp;amp;projid=11&amp;amp;disid=4'> What are these amps for ? why do they sit in between the action calls (made by link via url tag actions ) ? By the time I traverse back and forth in my web app, I get 10s and 20s of amp sitting in the request URL. What is the problem here ? Please help.

• Toshiba laptop only shows black screen with mouse pointer after starting up

  - by BubblySue

  I only see black screen after the startup. It just shows the logo and the status bar upon start, then it goes black screen with moveable cursor. I tried alt+ctrl+del, but it doesn't work. I pressed shift 5 times and it makes a sound. I already removed battery and restarted it, but still the same. I can go to safe mode and scanned thru there. Still, desktop won't show up. Don't know what else to check?

• Running a Ruby interpreter on iPad

  - by slothbear

  I'll be taking a trip soon with my iPad, without my laptop. I'd like to continue to tinker with Ruby while I'm on the road. I have an iPhone developer program membership, and I'm not interested in submitting this stuff to the app store. I found the shinycocos project, which appears to embed a Ruby interpreter in an app. But I can't get it to run, and it seems pretty customized for running cocos2d stuff. My first goal is to run an interactive command line like Try Ruby!. After that, I'd like to enter small programs in a UITextView and run them. I'd appreciate any clues, tips, or existing projects you might know of.

• How do I wrap this BAIL macro in Xcode?

  - by willc2

  I use this little snippet to halt my iPhone app in the simulator. NSAssert((0), @"Bail early while testing"); When I try to make it a #defined macro like this: #define BAILNOW (NSAssert((0), @"Bail early while testing")) I get this build error: error: expected expression before 'do' It seems to be related to the nesting of the NSAssert() macro but I'm at a loss as to how to get around it. Should I dig into the NSAssertionHandler docs or is there some simpler way to halt the app in it's tracks? Or should I just set a breakpoint and get on with my life?

• Validating call to web service against schema before sending request

  - by Cen

  I am calling a web service (written in Java) in my web app. I use the WSDL to generate proxy classes using the wsdl.exe command line tool. Everything is working fine. However, I have found out that the web service is not doing any data validation at all when they receive a request from my app. Hence, if I happen to send one minute piece of data that isn't exactly what they want, I receive a general fault error in return, with no specifics at all of what the incorrect (if any) piece of data is. So, before I make the request, I'd like to validate my request against the schema they have provided. Is this possible, and if so, how do I go about this? Thanks in advance

• Snow Leopard Hangs at Login Window

  - by jessecurry

  I've had an issue for the past few months, but I rarely restart so it hasn't caused too much trouble. Basically, when I start up my Mac (iMac10,1 - 3.06GHz Intel Core 2 Duo, OS X 10.6.3) everything proceeds as usual until I reach the login window. The login window displays normally, but keyboard and mouse input seem to be ignored. This condition persists for around 5 minutes at which time everything goes back to normal. While the login window is frozen my second monitor appears entirely blue, the second monitor receives a background as soon as the login window becomes responsive. If I startup while holding SHIFT the problem still occurs, but the freeze is much shorter. Looking through my logs I see no activity during the time that the login window is frozen. I've attempted to repair disk permissions, and gone through every possible maintenance option in Cocktail.

• Why does Oracle SQL Developer take so long to open?

  - by oscilatingcretin

  I think anyone who's used Oracle SQL Developer will agree that it's painfully slow on the load. My research has lead me to a solution that seems to have helped a little, and that's telling OSQLD not to check for updates on startup. However, it still takes several minutes to open. What could OSQLD possibly be doing during load time? Is there any way get it to open right away? Edit: Adding potentially relevant system specs: CPU: Intel i5-2520M 2.5 ghz Windows 7 32-bit RAM: 4 gb

• problem with struts actions and redirections

  - by Casey

  I am trying to update a simple web app that was built with struts2, jsp and standard servlets. I am trying to redirect a url to a specific action but can't seem to get it to work right. For example, the url that is correct is: http://localhost:8080/theapp/lookup/search.action Here is my web.xml: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app> <display-name>theapp</display-name> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> And here is my struts.xml: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <default-action-ref name="search" /> <action name="search" method="search" class="com.theapp.SearchAction" > <result>index.jsp</result> <result name="input" >index.jsp</result> <result name="error" type="redirect">site_locator_mobile/error.action</result> </action> The problem here is that if I don't specify the correct url as above, I just get the index.jsp file, but without any properties in index.jsp being processed because the information is contained in the servlet. What I would like to is if someone just entered: http://localhost:8080/theapp/lookup/ than they would be taken to: http://localhost:8080/theapp/lookup/search.action Thanks

• Context menu for loaded SWF

  - by Palantar

  I have a Flex app with a viewport that loads a series of other swfs. I would like to place a context menu over top of the SWFs when the user right-clicks. To that end, I have set up a fairly standard context menu where each item has a ContextMenuEvent.MENU_ITEM_SELECT event handler. One problem: The eventHandler never gets called. If I place the context-menu code anywhere else in the app, i.e. not on top of a loaded SWF, everything works fine. However, when I place the exact same code on the SWF viewport, the context menu items appear, but the eventHandlers are never called. Any ideas?

• iOS iPad Master Detail template can't interact with detail view

  - by CraigularB

  I have an iPad app generated from the Master-Detail template in XCode. The iPad Storyboard has under the Detail View Controller a View that holds a ScrollView which holds an ImageView. In the DetailViewController.m file I added the following code to allow the ScrollView to move and zoom the image: -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.comicImage; } This works great on the iPhone (it's a universal app) but not the iPad; I can scroll and zoom the image on the iPhone no problem, but on the iPad it's like the ScrollView isn't responding to the touches, and I can't figure out how to pass the touches on to the ScrollView. I've already deactivated the popover controller from appearing with a right swipe like this: self.splitViewController.presentsWithGesture = NO; How do I make it so the user can interact with the ScrollView in the DetailViewController?

• iPhone UIImage Display Controller

  - by Bill Shiff

  Hello, I would like to be able to display a UIImage from within my app and support a lot of the functionality available in the built-in Photos app (i.e., pinch-to-zoom, pan, etc). I don't really want to write a bunch of code that someone has already written, so I'm wondering if there is a library out there already that I could just import into my project. I'm aware of the Three20 project, but I don't want to import a huge library if I don't have to. Is anyone aware of an available library that's already out there for displaying UIImages? Or part of some open-source project that can be pulled out on its own? Thanks!

• Explorer fails to load with UAC enabled

  - by user37679

  While running an InstallShield based installer, my Windows 7 machine became unresponsive. After forcing a reboot, I can log in to the system, but explorer does not run. I can log in as a different user without issue and when I change UAC to its lowest setting, I can log in as the user that was performing the install. However, if I re-enable UAC, I am unable to get explorer to run again on login. I have checked the HKCU\Software\Microsoft\Windows\CurrentVersion\Run and RunOnce, but don't see anything that isn't configured to run on startup. I completed the installation of the software as the "good" user without issue.

• How does Core Data determine if an NSObjects data can be dropped?

  - by Kevin

  In the app I am working on now I was storing about 500 images in Core Data. I have since pulled those images out and store them in the file system now, but in the process I found that the app would crash on the device if I had an array of 500 objects with image data in them. An array with 500 object ids with the image data in those objects worked fine. The 500 objects without the image data also worked fine. I found that I got the best performance with both an array of object ids and image data stored on the filesystem instead of in core data. The conclusion I came to was that if I had an object in an array that told Core Data I was "using" that object and Core Data would hold on to the data. Is this correct?

• Deleting a node in a family tree

  - by user559142

  Hi, I'm trying to calclulate the best way to delete a node in a family tree. First, a little description of how the app works. My app makes the following assumption: Any node can only have one partner. That means that any child a single node has, it will also be the partner nodes child too. Therefore, step relations, divorces etc aren't compensated for. A node always has two parents - A mother and father cannot be added seperately. If the user doesn't know the details - the nodes attributes are set to a default value. Also any node can add parents, siblings, children to itself. Therefore in law relationships can be added. I have the following classes: FamilyMember String fName; String lName; String dob; String gender; FamilyMember mother, father, partner; ArrayListchildren; int index; int generation; void linkParents(); void linkPartner(); void addChild(); //gets & sets for fields Family ArrayListfamily; void addMember(); void removeMember(); FamilyMember getFamilyMember(index); ArrayListgetFamilyMembers(); FamilyTree Family family; void removeMember(); //need help void displayFamilyMembers(); void addFamilyMember(); void enterDetails(); void displayAncestors(); void displayDescendants(); void printDescendants(); FamilyMember findRootNode(); void sortGenerations(); void getRootGeneration(); I am having trouble with identifying the logic for removing a member. All other functions work fine. Has anyone developed a family tree app before who knows how to deal with removing various different nodes in the family "tree"? e.g. removing a leaf removing a leaf with partner (what if partner has parents etc) removing a parent It seems to be another recursive property but my head is swelling from over thought.
