  • How can I tell what files are currently open by a process (i.e. my app)?

    - by chaiguy
    I am using a Lucene.Net index and want to give the user an option to move the index, but am having trouble closing it down so the directory/contents can be moved (I keep getting access denied exceptions). I need to be able to have some more information so I can debug this problem, such as being able to tell what files are currently open, and as much information about each use as possible. Alternatively, is there any way to simply force close a bunch of files so they can be moved? This would make things a lot easier to solve.

  • How does my ASP.NET app get the SMTP settings automatically from web.config?

    - by Ryan
    I noticed that we always just are like: SmtpClient mSmtpClient = new SmtpClient(); // Send the mail message mSmtpClient.Send(mMailMessage); And the only place the credentials are set are in web.config: <system.net> <mailSettings> <smtp> <network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/> </smtp> </mailSettings> </system.net> So my question is, how does it automagically get them out?

  • What would you use for auto completion in Rails app?

    - by Andrei
    I want to use auto-completion in a number of fields (5-7) in my forms. There is a screencast on auto-completion with Prototype library by Ryan Bates ( http://railscasts.com/episodes/102-auto-complete-association). On the other hand, I have noticed that quite many guys suggest jQuery for this task ( http://jquery.bassistance.de/autocomplete/demo/). And I guess, there was probably some development last year(s), so I ask you - what would you use nowadays to auto-complete your form fields and why? BTW, I still have an open question on auto completion for HABTM association: http://stackoverflow.com/questions/1510935/how-to-do-habtm-management-with-auto-completion-in-rails

  • Possible to "next track" e.g. Spotify from my app?

    - by parse
    I'm planning on doing a application for Android 2.1 that changes song every minute (through what I hope exists in Android, "next track") for the application using the audio device atm. So if I have Spotify (http://www.spotify.com) running in background already, playing music, can I through my program change to the next track? Let me know if I was unclear about anything. Thanks in advance!

  • Need some advice before starting coding my next iPhone app...

    - by Tom
    Hi! I need some advice about how should I start coding something. So here is the context: I've just finished building a CMS that manage a SQLite database. My application will be picking this database and use its content as the application's content. So far it's pretty simple. The application will have a navigation that will browse through various workflows, and once at the end workflow, it'll show contents from the database. A consultation kind a thing, example: Liquids - Juice - Orange Juice - Informations about Orange Juice. For my SQLite transactions, so far I believe I'll be using fmdb. It looks like a great wrapper. Here's a simple schema from one of the database: Workflow: id: { type: integer(3), primary: true, autoincrement: true } workflow_id: { type: integer(1) } name: { type: string(255) } That table's rows will be my navigations. Do you believe I should use a navigation controller? If so, then how could I generate the navigation tree from it? I have a good working knowledge of Objective-C and Foundation framework, but never went too far with it so that is why I'm asking before starting in the wrong direction :) Thanks a lot.

  • How do I create a point system in a Rails app that assigns points to users and non-authenticated-use

    - by codyvbrown
    I'm building a question and answer application on top of twitter and I'm hitting some snags because I'm inevitably dealing with two classes of users: authenticated and non-authenticated. The site enable users to give points to other users, who may or may not be authenticated, and I want to create a site-wide point system where the application stores and displays this information on their profile. I want to save this point data to the user because that would be faster and more efficient but non-authenticated users aren't in our system, we only have the twitter handle. So instead we display the points in our system like this: @points = point.all( :select => "tag, count(*) AS count", # Return tag and count :group => 'tag', # Group by the tag :order => "2 desc", :conditions => {:twitter_handle => params[:username]}) Is there a better way to do this? Is there a better way to associate data with non-authenticated users?

  • Why are the default UI controls in my iPhone app blurred?

    - by Tom H
    Why would the default iPhone interface elements, specifically the UISwitch (unmodified) and a UISegmentedControl appear slightly blurred? I have not changed them or called any private APIs. This blurring occurs when I run it both in the simulator and when I load it on my iPod Touch, so I don't think it's a one off drawing glitch. These elements were created via some code (initWithFrame:) not in interface builder. Here is a screenshot of the blurring in the simulator: http://drp.ly/14rS6a It looks similar on the actual device. Thanks for your help

  • Can my app arrange a gdb breakpoint or watch?

    - by Larry Gritz
    Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

  • How to set the ReturnUrl for the Login link in MVC 3 app?

    - by user762196
    using System; using Microsoft.Practices.Unity; namespace <MyNameSpace> { public class UrlFactory { public static UrlFactory Current { get { return HttpApplicationUnityContext.Current.Resolve<UrlFactory>(); } } public string GetLoginUrl() { return String.Format("{0}/login?ReturnUrl={1}", MyConfig.BaseHttpUrl, <GET_PAGE_URL>); } } The user can be on any page on the site and click the Login link. But the ReturnUrl must always point to the exact page where he clicked it. I must take the user back to the page he clicked the login link. In my code above, how do I get the page url in <GET_PAGE_URL>? Thanks

  • How does the NY Times iPhone app do this?

    - by ArgMan
    Alright, I have an RSS feed that gets arranged in a UITableView and then the user selects a story and it loads in a UIWebView. However, I'd like to stop using the UIWebView and just use a UITextView or UILabel. This png is what I am trying to do (just display the various text aspects of a news story): http://img411.imageshack.us/img411/2449/screenshot20100315at120.png Let me start off by saying that I have tried to use the usualNSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"]; and assign it to a UILabel, but it doesn't work the way that I am implementing it (in webViewDidFinishLoad--is that not correct?) and I get a blank textView and normal webView. If I overlay a UITextView on top of a UIWebView on its own (that is, a webView that just loads one page), the code posted above works fine to display the text I require, but the problem arises when the RSS feed is added into the mix. Ideas and/or help, guys? I've been stuck wondering why this doesn't work as it should for a few days now. If you have a better, more efficient way of doing it then placing the code in webViewDidFinishLoad, please let me know! Does it go in my didSelectRowAtIndexPath? I'm lost here, guys. Thank you very much in advance!

  • Android: Best way/library to write an app that simply gets/sets your Facebook status, sends Facebook

    - by D.
    I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature"). Thanks for any help.

  • iPhone app. Creating a custom UIView that contains UITextField and UIButton.

    - by Dmitry Burchik
    Hi all. I am new to iPhone programming. And I have an issue. I need to create a custom user control that I will add to my UIScrollView dinamically. The control has an UITextField and an UIButton. See the code below: #import <UIKit/UIKit.h> @interface FieldWithValueControl : UIView { UITextField *txtTagName; UIButton *addButton; } @property (nonatomic, readonly) UITextField *txtTagName; @property (nonatomic, readonly) UIButton *addButton; @end #import "FieldWithValueControl.h" #define ITEM_SPACING 10 #define ITEM_HEIGHT 20 #define SWITCHBOX_WIDTH 100 #define SCREEN_WIDTH 320 #define ITEM_FONT_SIZE 14 #define TEXTBOX_WIDTH 150 @implementation FieldWithValueControl @synthesize txtTagName; @synthesize addButton; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code txtTagName = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, TEXTBOX_WIDTH, ITEM_HEIGHT)]; txtTagName.borderStyle = UITextBorderStyleRoundedRect; addButton = [UIButton buttonWithType:UIButtonTypeContactAdd]; [addButton setFrame:CGRectMake(ITEM_SPACING + TEXTBOX_WIDTH, 0, ITEM_HEIGHT, ITEM_HEIGHT)]; [addButton addTarget:self action:@selector(addButtonTouched:) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:txtTagName]; [self addSubview:addButton]; } return self; } - (void)addButtonTouched:sender { UIButton *button = (UIButton*)sender; NSString *title = [button titleLabel].text; } - (void)drawRect:(CGRect)rect { // Drawing code } - (void)dealloc { [txtTagName release]; [addButton release]; [super dealloc]; } @end In my code I create an object of that class and add it to scrollView on form. FieldWithValueControl *newTagControl = (FieldWithValueControl*)[[FieldWithValueControl alloc] initWithFrame:CGRectMake(ITEM_SPACING, currentOffset + ITEM_SPACING, 0, 0)]; [scrollView addSubview:newTagControl]; The control looks fine, but if I click to the textbox or to the button nothing happens. Keyboard doesn't appear, the button is not clickable etc.

  • Why did my ASP.NET Web App stop showing AM in times?

    - by qntmfred
    I haven't made any code or configuration changes (that I know of) to my ASP.NET web application and this morning it suddenly stopped showing the AM in my displayed times. PM still shows up, just not AM. It's hosted on Windows Server 2003. I figured somehow the OS regional settings might have been changed somehow, but that doesn't appear to be the case. How could this have happened?

  • How to update to jersey 2.X on an app using jersey 1.1X?

    - by Maxrunner
    i recently faced a problem with the handling of exceptions using jersey. In this case it was that the exceptions thrown from Exception mapper are not re thrown to the underlaying container, i searched and found that this has been fixed in the 2.0 version. But i'm using jersey 1.10 and the 2.X dependencies are all different and its also maven based. Since this project is not using maven, how do i use the more recent version?In the 2.X versions there are no jackson json jars for example. So i'm having some doubts in how to upgrade. Here's my web.xml config entry for jerse <servlet> <servlet-name>Jersey REST Service</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.mobile.rest.resources</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Jersey REST Service</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> regards,
