• Using Geo APIs to pick a random town from anywhere in the world

  - by Dan Forys

  Hi all, I'm trying to use Yahoo's excellent GeoPlanet API: http://developer.yahoo.com/geo/geoplanet/guide/api-reference.html I would like to pick a random town from anywhere in the world but can't see an easy way to do it. I have tried querying by country and asking for children of type 'town', but can't seem to do that directly. Can anyone think of a way to pluck out a random town WOEID without having to query the country, then the admin regions, then the admin 2, then the admin 3 etc. I have also experimented using YQL, but don't have enough of an understanding about the available APIs.

• VWD Express won't let me add one table!

  - by user530809

  Sorry if this question is too trivial but I really haven't found any related questions and I am shaking too much to think logically. I spent like few hours waiting for SQL Server to finally install (you know, it's Microsoft) and now when I want to add new table to database it says "this feature is not supported by Microsoft Visual Web Developer Express". How could this happen? I mean, what's the point of even letting me use this if I can't even add one table to database, and I won't even know about it until I actually need to do it? Are they really serious or is it just some mistake? Is there any way to get around this problem? I need to create just one simple project with one small table in database but it won't let me, but I can't believe they could actually have nerves to make express edition without such a trivial function, so maybe I just made something wrong and there's actually some way to add this table? Sorry for being so whiny but I'm just fed up with this environment.

• Integration of Magento with third party CRM, POS and ERP solutions

  - by SIA

  Hi there, First of all I would like to Thank the Varien Company for providing the best ecommerce solution and free community edition. I am very excited since i started knowing about magento. I am a web developer and very much interested. I have some concerns about the Integration of Magento with other CRM,ERP systems. How is it possible to integrate Magento with any other Industry standard CRM and ERP system? How can i fetch the data from a ERP and update Magento database, like transactiona replication. Is this possible? And Whats the right way to do it? Also, How can i integrate Magento with POS? Is it possible to have bi-directional data update between Magento and Industry Standard POS? I hope I have stated all my doubts and made it clear. I would be thankful if someone guides me to do the integration, the Right way. Thanks and Regards SIA

• C# PropertyGrid drag drop

  - by gametheoryonline

  I'm trying to implement drag/drop support to a propertygrid in C# using VS2005 (.NET 2.0). The propertygrid can handle the dragenter etc. events, but there doesn't seem to be a way to get the griditem under the pointer during a drag event. The best I've been able to get so far is to use the selectedgriditem property to retrieve a custom propertydescriptor and set the value, but this requires a grid item to already be selected before starting the drag/drop operation. Has anyone had any luck with implementing this? Thanks :-)

• Jenkins and Visual Studio Online integration authentication

  - by user3120361

  right now I am trying to Setup Continuouse Integration - Delivery for a basic WCF Service, which will be hosted on a Microsoft Azure VM. The Project is Version Controlled through Visual Studio Online. So I installed Jenkins (also on the Azure VM), TFS plugin etc. and started the first Test Build: As Server URL I used "[VSO Adress]/DefaultCollection" and for Login purposes my Microsoft Account (I can Access VSO with that). The Problem is, when I run the Build I get the following error: Started by user Developer Building in workspace C:\Program Files (x86)\Jenkins\jobs\test\workspace [workspace] $ "C:\Program Files (x86)\TEE-CLC-11.0.0.1306\TEE-CLC-11.0.0\tf.cmd" workspaces -format:brief -server:[VSO Adress]/DefaultCollection ****" An error occurred: Access denied connecting to TFS server [VSO Adress] (authenticating as har****@*******o.com) FATAL: Executable returned an unexpected result code [100] ERROR: null Finished: FAILURE So my question is, whether it is generally possible to connect Jenkins and VSO that way and if so, which login credentials are needed

• In XAML is there way to bind key press and key release to specific commands?

  - by Ashley Davis

  In my application I have keys that bound to commands using the KeyBinding class. The command is executed when the key is pressed and released. I have a special case where I want to bind separate commands to the pressed action and to the released action. For example when the space key is pressed I want my app to run a command to enter a special mode. Then when the space key is released I want to run another command to exit that special mode. Currently I do this by manually handling the KeyUp and KeyDown events. Is there anyway to execute commands for pressed and released purely in XAML?

• Does UIActivityIndicator require manual threading on iPhone

  - by Akusete

  I am running creating an iPhone application which performs a costly operation and I wanted to create an activityIndicator to let the user know the application has not frozen. The operation is performed entirely in one event call... so there is no chance for the UI framework to receive control to actually display and animate this indicator. The sample apps which use the UIActivityIndicator (or any other similar animation) start and stop the animation in different events, triggered separately at different stages of the program. Do I need to manually create a separate thread to run my operation in, or is there already default support for this kind of behavior?

• Is there a Tool for see files created with binary serialization?

  - by Néstor Sánchez A.

  I've working without problems serializating object graphs to and from files. Everything was fine until today: A dictionary, created in a constructor and NEVER deleted, was lost (null referece) just after deserialization from file, for the first time in more than a year doing the same without troubles. So, is there a Software Tool to look into binary serialization content showing a human/developer-readable version (a la Reflector) of what is stored? AKA: How to analyze (easy, no binary to IL translation. That would take months) binary serialized content? Thanks!

• How do I set permissions on a Server 2003 folder

  - by Richard210363

  Hi There, In my part time position as entire IT department at my Office ( I'm a MCSD developer normally ) I have been asked to change a shared folder. Only I don't really understand all the Shared / Security options. I have a folder that must be accessed by 2 people in the company (and no one else). They both must have read/write/edit and change access. They must be able to read/write/edit each others files; existing or newly created. Should be easy but I'm a bit overwhelemd by all the choices. What should I set? Thanks for your help richard

• What turns away users/prospective users?

  - by Zach Johnson

  In your experience, what kinds of things have turned away users and prospective users from using your programs? Also, what kinds of things turn you away from using someone else's programs? For example, one thing that really bugs me is when someone provides free software, but requires you to enter your name and email address before you download it. Why do they need my name and email address? I just want to use the program! I understand that the developer(s) may want to get a feel for how many users they have, etc, but the extra work I have to do really makes me think twice about downloading their software, even if it does really great things.

• Software Protection: Shuffeling my application?

  - by Martijn Courteaux

  Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

• How to cause bindings to be updated, particularly for derived values?

  - by rrhartjr

  I'm using some CLR objects that use the INotifyPropertyChanged interface and use the PropertyChanged function to update in WPF bindings. Pretty boilerplate: protected void RaisePropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Then the property: private double m_TotalWidgets = 0; public double TotalWidgets { get { return m_TotalWidgets; } set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); } } Is there a better way to update a derived value or even the whole class? Say I had a calculated value: public double ScaledWidgets { get { return TotalWidgets * CONSTANT_FACTOR; } } I would have to fire ScaledWidget's PropertyChanged when TotalWidgets is updated, eg: set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); RaisePropertyChanged("ScaledWidgets"); } Is there a better way to do this? Is it possible "invalidate" the whole object, especially if there are a lot of derived values? I think it would be kind of lame to fire 100 PropertyChanged events.

• Why avoid pessimistic locking in a version control system?

  - by raven

  Based on a few posts I've read concerning version control, it seems people think pessimistic locking in a version control system is a bad thing. Why? I understand that it prevents one developer from submitting a change while another has the file checked out, but so what? If your code files are so big that you constantly have more than one person working on them at the same time, I submit that you should reorganize your code. Break it up into smaller functional units. Integration of concurrent code changes is a tedious and error-prone process even with the tools a good version control system provides to make it easier. I think it should be avoided if at all possible. So, why is pessimistic locking discouraged?

• Saving WPF WIndow and Position

  - by moogs

  What would be the best way to save the window position and size in a WPF app? Currently, I'm saving the window size and position of a WPF App. Here are the events I handle: SourceInitialized : The saved info is loaded on to the window WindowClosing : The current info is saved to the backing store (I copied this from an example). The problem is, when the window is minimized and restored, the settings from the last WindowClosing is retrieved. Now, the StateChanged event fire AFTER the window has minimized, so it does not seem to be what i need. Thanks

• Form Inheritance in Visual Studios designer implementations

  - by CooPzZ

  I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

• How to automate the finding of an M value along a route

  - by Heather Taylor

  Kirk Kuykendall had given a script example a few years back in an ESRI forum http://forums.esri.com/Thread.asp?c=93&f=996&t=88246&mc=4 as to how to find the M (measure) value of a point in a shapefile along a route when you clicked on the point. This is very handy, BUT..I have 1500 points that I need M values for. Is there a way to automate this type of thing? I need the M values for the points to create linear events on the route. Note: I am not a programmer, but have people who can help me out.

• How to display the dynamically created elements for some time?

  - by Holicreature

  i have some rows of data displayed in a table and on mouse over of each row i've list two buttons inside a div element and then display it for some time. And i've associated some functions to be called on clicking the buttons that are dynamically created and displayed elements.. So what i did was i wrote a function which will create elements dynamically and place them exactly where i wanted using styles. And i wrote another function which will remove these dynamically added elements. I called them on mouseover and mouseout events of the row. now when i move mouse out the row to click the button they get disappeared bcoz of my mouseout function. So how can i proceed this? And what is the perfect method to create these kind of stuffs?

• Documenting and defining content types for a CMS or similar project

  - by Rimian

  I'm writing up some documentation on a Drupal project and my task is to define the content types and their attributes. The intended audience is project managers and developers. So it could be a high level document that gives an overview of the system. (I think that's how I describe it: high level rather than high detail) At the moment I'm using open office and bullet points but it seems like an amateurish method when I need to describe details that could be useful for a developer (me). Something like UML would describe detail but is probably more complicated than I need right now and could be too technical for others on the team. Are there any universal methods or templates that I can use to describe information in this case?

• Where/When does C# and the .NET Framework fail to be the right tool?

  - by Nate Bross

  In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

• How to bind a complex dictionary to a Gridview in asp.net?

  - by Mehdi

  I've used an early binding of a dictionary<string, string> to a gridview to show Urls Text and its HRef as key-value and it works like a charm. But since I want to replace the dictionary with this one : dictionary<string, LinkInfo> the binding goes wrong! Should I handle some events like as onItemDataBound or something? and the LinkInfo structure is: public struct LinkInfo{ public string href; public bool Enabled; }

• Tracing\profiling instructions

  - by LeChuck2k

  Hi Y'all. I'd like to statistically profile my C code at the instruction level. I need to know how many additions, multiplications, devides, etc,... I'm performing. This is not your usual run of the mill code profiling requirement. I'm an algorithm developer and I want to estimate the cost of converting my code to hardware implementations. For this, I'm being asked the instruction call breakdown during run-time (parsing the compiled assembly isn't sufficient as it doesn't consider loops in the code). After looking around, It seems VMWare may offer a possible solution, but I still couldn't find the specific feature that will allow me to trace the instruction call stream of my process. Are you aware of any profiling tools which enable this?

• I/O Asynchronous Completion

  - by lockedscope

  In the following, it is said that an I/O handle must be associated with the thread pool but i could not find where in the given example an handle is associated with the thread. Which function or code helps to bind the file handle in that example? Using asynchronous I/O completion events, a thread from the thread pool processes data only when the data is received, and once the data has been processed, the thread returns to the thread pool. To make an asynchronous I/O call, an operating-system I/O handle must be associated with the thread pool and a callback method must be specified. When the I/O operation completes, a thread from the thread pool invokes the callback method. http://msdn.microsoft.com/en-us/library/aa720215(VS.71).aspx

• Solution: Android INSTALL_FAILED_INSUFFICIENT_STORAGE error.

  - by Andrew Smith

  The INSTALL_FAILED_INSUFFICIENT_STORAGE error is the bane of every Android developer's life. It happens regardless of app size, or how much storage is available. Rebooting the target device fixes the problem briefly, but it soon comes back. There are hundreds (if not thousands) of message board posts from people asking why the problem occurs, but the folks at Google are frustratingly silent on the issue. There is a simple workaround. If your test device is running Android 2.2 or later then add the android:installLocation attribute to your application's manifest file, with the value "preferExternal". This will force the app to be installed on the device's external storage, such as a phone's SD card. For example: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andrewsmith.android.darkness" android:installLocation="preferExternal" This is more of a band-aid than a fix, and it may not be ideal if you want your finished app to install on the device's internal memory. But it will at least make the development process a lot less frustrating.

• Does Google provide any Android tutorials that teach how to implement a Service?

  - by Bub

  I apologize in advance for the "newbie" nature of this question. Here is my predicament: I'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction? On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)? Any suggestions would be appreciated.
