• Adding a new view to a Window-based app (re: MapKit tutorial)

  - by blackkettle

  I'm trying add a new view in a window-based application but not really getting anywhere. I've been going through a great MapKit tutorial lately, http://mithin.in/2009/06/22/using-iphone-sdk-mapkit-framework-a-tutorial/ and have successfully set it up and added some further buttons and customizations. However I've gotten stuck at what I assume ought to be a brain-dead simple step. I have added a toolbar to the bottom of the app, and a 'settings' style button. Following this I created a SettingsViewController complete with it's own view. Now I'd like to connect them but I've had absolutely no luck trying to figure out how to do this. I've also gone through several other good tutorials lately, http://miketeo.net/wp/index.php/2008/08/31/simple-iphone-tutorial-part-1.html http://blog.webscale.co.in/?p=228 http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html but I've gotten lost trying to tie these two bits together. I'm sure it is quite trivial to link these two items but I've had no luck.

• Why would a TableAdapter populate a DataSet with "1/1/2000" for an entire timestamp column?

  - by Rob

  I have a TableAdapter filling a DataSet, and for some reason every select query populates my timestamp column with the value 1/1/2000 for every selected row. I first verified that original values are intact on the DB side; for the most part, they are, although it seems a few rows lost their original timestamp because of update queries performed programmatically before the issue was discovered. The DataColumn type is DateType, while the database (Postgres) column type is timestamp. Up until recently, this was all playing very nicely. I noticed the issue in a bound DataGridView control, and verified that this is not related to data binding by utilizing the 'Preview Data' option in the VS DataSet Editor. Usually when I notice unexpected values popping up in my application it's related to a mis-configured property, type conflict, or another silly mistake I've made. So after checking properties and types, and even recreating the TableAdapter from scratch, to say I'm a little baffled is an understatement. Does anyone have any ideas of what I could do to fix the issue and/or diagnose the cause?

• Java Socket Disconnect Reporting vs. C# Disconnection

  - by ikurtz

  in C# when a sockets connection is terminated the other node is informed of this before terminating the link thus the remaning node can update the connection status. in Java when i terminate a communication link the other node keeps reporting the connection as valid. do i need to implement a read cycle (makes sense) that reports the connection as lost when it recieves a -1 during read (in C# this is 0 i think)? thank you for your insight. EDIT: thanks to you both. as i suspected and mentioned in my post that an additional check is required to confirm the connected state of a connection.

• 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!

• Move websites from IIS7 to IIS 7.5

  - by Adam Winter

  Can anyone suggest the best way of moving websites on server1 with IIS7 to server2 with IIS 7.5 on it? I've read some articles which suggest copying the applicationHost.config file while preserving the configProtectedData node, but I'm concerned there may be settings in the IIS 7.5 config that don't exist in the current IIS7 config which would be lost. I've also seen suggestions of moving each site individually by using a command like this: AppCmd.exe LIST SITE "My Site" /config /XML mysite.xml This method just takes too long to do this for dozens of sites. There must be a better way of moving all the sites at once to the new platform.

• Difficulty to start up with basic unit test (Sample from my book -- SportsStore)

  - by Richard77

  Hello, I'm really new in TDD and, actually, I'm trying to follow the sample from my book (SportsStore -- Pro ASP.NET MVC Framework/Steve Sanderson/APRESS). I'm on pages 103-105. Although there are more on this, as new to all of this, I'm concerned with the following statements. ProductsController controller = new ProductsController(repository); var result = controller.List(2); //... regarding the above statements, when I write this (as in the book), var products = result.ViewData.Model as IList<Product>; I get a compiler error "System.Web.MVC.ActionResult" does not contain a definition for ViewData ..." But, when I remove the List() from the statement, then the compiler error disapear. var result = controller.List(2);//Doesn't work var result = controller;//It works Is something wrong there? I checked Apress website for that book, but there is nothing listed as Errata or issue. So I'm really lost. Thanks for helping

• Retain, alloc, properties ... Topic to make your Obj-c life easier !

  - by gotye

  Hey everyone, The more I code, the more I get lost ... so I decided to create a topic entirely dedicated to the memory management for me (and others) not to waste hours understanding obj-c basics ... I'll update it as new questions are asked ! Okay below is some examples : // myArray is property (retain) myArray = otherArray; //myArray isn't a property myArray = otherArray; //myArray is a property (retain) myArray = [[NSArray alloc] init]; //myArray isn't a property myArray = [[NSArray alloc] init]; Could you explain to me what happens in every cases ? And especially the number 3 ;) Thanks for the time. Gotye.

• Ant - using vssadd to add multiple file

  - by mamendex

  Hi, I'm trying to use vssadd task to add a tree of source files to a recent created project on VSS. But it happens to be adding only the folder tree, all files missing. <vsscp vsspath="$/DEV/APL_${version}" ssdir="${vssapl}" serverPath="${vsssvr}"/> The vssadd task displays the name of the folders it's creating: ... (vssadd) $/DEV/APL_0.0.10c/src/domain: (vssadd) $/DEV/APL_0.0.10c/src/mbeans: (vssadd) $/DEV/APL_0.0.10c/src/service: ... The script runs successfully but the files never get in the repository. Trying to use wilcards are no good, the task says it found no matching files and ss returns with a code of 100: <vssadd ssdir="${vssapl}" localPath="C:\Workspace\APL_Build*.*" recursive="true" serverPath="${vsssvr}" comment="Build ${versao} at ${to.timestamp}"/ I've noticed that vssadd does not accept fileset tag either, so I'm kind of lost here. Any tips? tks

• How to force a node inside tiny mce ?

  - by KutePHP

  Hi All, I'm using tiny mce for my project and want to validate the node inside the tiny mce. On click of a text element, let's say a paragraph with some id, I load editor for the element. But, sometimes if user replaces the whole content, the node and its HTML is lost. I want to retain this node and only the content is removed. The node can be a paragraph or heading or ul or ol. EDIT : I'm providing dummy text such as "Lorem epsum .....". User will be removing this dummy text and add his content. How can I accomplish this ?

• Yet another Rails routing question

  - by danhere

  I can't seem to grasp the Rails routing just yet. I want to be able to link the site to, for example, ...com/store/xbox360/Mass Effect 2 (which is /store(my controller)/:system/:title). I have the database entries that include the :system and :title variables (?). How would I route these to show up and filter these entries? Or is this something I need to set up in the controller? I'm lost. Thanks so much for your help.

• vim - how am I suppose to read this command to remove all blanks at the end of a line

  - by whaley

  I happened across this page full of super useful and rather cryptic vim tips at http://rayninfo.co.uk/vimtips.html. I've tried a few of these and I understand what is happening enough to be able to parse it correctly in my head so that I can possibly recreate it later. One I'm having a hard time getting my head wrapped around though are the following two commands to remove all spaces from the end of every line :%s= *$== : delete end of line blanks :%s= \+$== : Same thing I'm interpreting %s as string replacement on every line in the file, but after that I am getting lost in what looks like some gnarly variation of :s and regex. I'm used to seeing and using :s/regex/replacement. But the above is super confusing. What do those above commands mean in english, step by step?

• For REST, how do I receive posted data using PHP?

  - by netrox

  I want to set up a tiny RESTful interface for my web services using PHP. The problem is that I looked at frameworks and I cannot figure out how do I recieve the posted data without field names? For example, if a server posts data to my server, I cannot figure out how do I get it without needing the postfield (POST variables). Traditionally, with forms, people send post data with field names such as this: curl_setopt($ch, CURLOPT_POSTFIELDS, postfield=postvalue); and I would use PHP code like this: $postvalue=$_POST[postfield]; to get value of postfield but since the server posting data is not using postfield and is just sending XML, how do I get it without fields? How do I capture the XML? That's where I am lost.

• facebook php-sdk not logging out

  - by Meisam Mulla

  I'm having a hard time getting this to work. I use the following to generate the logout url: $logout = "https://www.facebook.com/logout.php?next=" . urlencode('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF']) . "&access_token=" . $facebook->getAccessToken(); Which generates the correct (worked with the last version) url: https://www.facebook.com/logout.php?next=http%3A%2F%2F...&access_token=AA....ZD However this does not actually log the user out. I tried using $facebook->getLogoutUrl(array('next' => 'myurl')) which generates pretty much the same url. This also did not work. I am lost as to why its not logging the user out. I actually tried manually putting the address into the address bar but it redirects me to the Facebook homepage.

• MediaElement seems to disable lock screen when playing a video

  - by CrossProduct

  I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

• Remapping design issue

  - by Sirupsen

  Hello, I'm currently developing a Ruby Gem and I'm a bit lost on the design currently. Basically, I'm remapping some APIs, so my skeleton is something like this: module MyApp module SomeApi class Function > Base::Function ... end class Function2 > Base::Function2 ... end ... end module SomeApi2 ... end class RemappedFunction def initalize # set some values and stuf ... end def remapped_method # Problem: # How would I know, if I should take contact to # SomeApi, or SomeApi2? end end def interact_with(api) # What would be the best way of letting RemappedFunction # know which API to use? end end someapi2 = MyApp.interact_with(:someapi2) someapi2.remapped_method Any ideas?

• Delphi - How to prevent Forms/MsgBoxes to move under prior form?

  - by durumdara

  Hi! Many times we experienced after Windows 98 era that some dialogs are lost their Z-Order, and moved back to prior form. For example: Dialog1.ShowModal; Dialog1.OnClickButton() : ShowMessage('anything'); When MessageBox appears, sometimes not got focus, it is moved under Dialog1. The users confused on it, because they are say: application freezed!!! But if they are uses AltTab to move another app and back, the focus return to the MessageBox, and it will be the foreground Window. We experienced this with ShowMessage, MessageBox, normal forms, QuickReport forms also. Is anyone knows about this? Is it Windows bug? How to prevent it? How to catch this? Thanks for your help: dd

• JQuery: which element was clicked?

  - by centr0

  I have a list with links. These links are links to tables on the same page. What I want to do is whatever link I click in the list it will show its corresponding table and hide all the others. Without adding a different id/class to each link in the list and its corresponding table, is there a way to find out which element was clicked and show() its table? From what I understand JQuery returns an array object on its selector. How can I find out what element of the array was clicked? I've tried to use event.which but I'm a little lost. Help is greatly appreciated!

• Learning Python coming from PHP

  - by Coronatus

  Community wiki so don't vote to close, kthxbai. My dynamic language experience is solely PHP. I want to learn Python now to broaden my career opportunities and just because I like programming. :) When learning Java, I used a site (lost the URL/real name now), something like "Java for PHP developers" that had all on one side of the page the PHP code, and on the other side the Java code to do the same thing. Is there a website like that for Python? Any other recommendations/advice? Thanks Edit: I have no votes left today, but I'll up-vote good answers tomorrow :)

• What combination of project-management software will meet my just-started project's needs?

  - by taz

  Hello all, I have a got couple of software projects that I want to run with my friends(max 10 persons) privately(at least for now). But I'm kind of lost between software management systems. I am not even sure about the definitions of my needs. Dear all, what is the definition/name of the system/software that meets my needs listed below? Continuous Integration? And please suggest me a good ALL-IN-ONE instance of it: project roadmap/planning project resource(people) allocation project issue&bug tracking project mailing list project forum project wiki source control server source control client repository change notifier client build system(like scons) nightly build automation IDE integration(VS) Note: I tried Redmine and liked it, but found it kind of slow. All-in-one kind ones will be the most appreciated but if your suggestion includes more than 3 softwares, please suggest me the ones that work together painlessly. thanks in advance..

• Popuplating an NSPopupButton with the contents of two NSArrayControllers

  - by ndg

  I'm looking to populate an NSPopupButton with the contents of two NSArrayControllers. The NSArrayControllers are both bound to my Core Data Managed Object Context and represent separate entities (in this example: Person and Department). Within my NSPopupButton, I would like a list of departments, and the people that work under them. Like so: Department 1 Person 1 Person 2 Department 2 Person 3 Person 4 All departments would need to be disabled by default, meaning that users should only be able to select people listed within the dropdown. I'm lost as to how I would go about doing something like this. The concept of manually populating an NSPopupButton seems fairly trivial, but I'm a bit shaky as to best to populate the element with Core Data objects. Essentially, I'm just looking for someone to point me in the right direction. I imagine there's a right way to do this, and a number of very wrong ways.

• need to query MongoDB using php

  - by Mario Villarroel

  I need to query mongodb with something like this: ("something" < X OR "something" = "nll") AND ("someother"X OR "someother"= "nll") AND z=$z AND s=1 I've tried a few things, but can't get it to work, this is what I've tried: find( array( '$or'=array(array("something"=array("$le",$X)),array("something"="nll")), '$or'=array(array("someother"=array("$ge",$X)),array("someother"="nll")) )) But that's getting me the OR overwritten, so I'm lost on that... After diggin a bit more, I assembled this code that seems to be what I need, but doesn't work either: find( array('$and'=array( array( '$or' = array( array("something"=array('$gte'=$X)),array("something"="nll"))), array('$or' = array( array("someother"=array('$lte'=$X)),array("someother"="nll")))),"Z"=$z, "s"="1"); But this doesn't work as it returns zero results and I know for sure that there are more than 2 items that match on the db. (100% certain)

• How to learn to program C the right way

  - by sfactor

  i have been programming in C/C++ for my academic courses a lot and was under the impression i had a pretty good grasp of it. but lately i had to work in a bluetooth application that had a server and client implementation in a Linux box and an embedded system. i learned bluez bluetooth API, socket/network programming and coded it. however i ran into a lot of problems with memory leaks and segmentation faults and other memory related errors along the way.as the code grew more complex i all but lost control of the pointers and threads and sockets. this got me wondering that i had a lot to learn that they didn't say in the basic C/C++ books. so i wanted to ask for the resources that are available that'll help be code better in a professional way in C/C++ .especially for the Linux/Mac environment (gcc compiler).

• where do i put html files in my web-app folder for a lift project with maven?

  - by egervari

  I'm new to Lift framework for scala. For some reason, index.html resides in the web-app directory, and when I start up jetty, http://localhost:8080/ will point to that index.html file just fine. However, if I put a login.html file in the same folder as the index.html, and then go http://localhost:8080/login, Lift does not serve the file. Where do I need to put the files to get them register? I am a little lost because the behaviour only seems to work for index.html and nothing else. This is what happens when I view source in Chrome: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body>The Requested URL /login was not found on this server</body> </html>
