  • How do I programmatically trigger a mx:Button click event?

    - by knorv
    Consider the following mx:Button: <mx:Button click="doSomething()" id="myButton"/> Is there some way to programmatically emulate the user clicking the button? One obvious way to do it would simply be to call doSomething() which would give the same end result as clicking the button. But I'm specifically looking for ways to emulate the click -- that is something along the lines of myButton.click() (if that should have existed).

  • Why is good UI design so hard for some Developers?

    - by Chris Ballance
    Some of us just have a hard time with the softer aspects of UI design (myself especially). Are "back-end coders" doomed to only design business logic and data layers? Is there something we can do to retrain our brain to be more effective at designing pleasing and useful presentation layers? Colleagues have recommended a few books me including The Design of Sites, Don't make me think and Why Software sucks , but I am wondering what others have done to remove their deficiencies in this area?

    - by user1661826
    Is there any function in Objective-C to print a list of elements as unordered HTML elements. For ex - [@"a--b-c---d" htmlList: @"--"] returns @ "ab-c-d" the "--" is the delimiter to seperate the string of elements. I have used NSSArray to store the input string and function componentsSeperatedByString:@"--" to get the elements. How do I go ahead in adding the HTML tags li and /li between elements and ul and /ul at the end of the entire list? Please help, Im a beginner in objective -C

  • get attributes from xml tree using linq

    - by nelsonwebs
    I'm working with an xml file that looks like this: <?xml version="1.0" encoding="UTF-8"?> <element1 xmlns="http://namespace1/"> <element2> <element3> <element4 attr1="2009-11-09"> <element5 attr2="NAME1"> <element6 attr3="1"> <element7 attr4="1" attr5="5.5" attr6="3.4"/> </element6> </element5> <element5 attr2="NAME2"> <element6 attr3="1"> <element7 attr4="3" attr5="4" attr6="4.5"/> </element6> </element5> </element4> </element3> </element2> </element1> Where I need to loop through element5 and retrieve the attributes in an Ienumberable like this: attr1, attr2, attr3, attr4, attr5, attr6 using linq to xml and c#. I can loop through the element5 and get all the attribute2 info using but I can't figure out how to get the parent or child attributes I need. UPDATE: Thanks for the feeback thus far. For clarity, I need to do a loop through attribute5. So basically, what I have right now (which isn't much) is . . . XElement xel = XElement.Load(xml); IEnumberable<XElement> cList = from el in xel.Elements(env + "element2").Element (n2 + "element3").Elements(n2 + "element4").Elements(ns + "element5") select el; foreach (XElement e in cList) Console.WriteLine(e.Attribute("attr2").Value.ToString()); This will give me the value all the attr 2 in the loop but I could be going about this all wrong for what I'm trying to acheive. I also need to collect the other attributes mentioned above in a collection (the Console reference is just me playing with this right now but the end result I need is a collection). So the end results would be a collection like attr1, attr2, attr3, attr4, attr5, attr6 2009-11-09, name1, 1, 1, 5.5, 3.4 2009-11-09, name2, 1, 3, 4, 4.5 Make Sense?

  • Extract two double Values from String using RegEx in Java

    - by tzippy
    I am reading a file by line and need to extract latitude and longitude from it. This how lines can looks: DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278 DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10 What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles. Unfortunately there are Values without a dot, so it's probably best to check for numbers from the end of the String. thanks for your help!

  • Tracking SVN changes through multiple merges

    - by Paul D.
    At work we use a branching strategy where all changes start off in a development branch, then subsequently make their way through one or more integration branches, and finally end up in a release branch. Occasionally (more often than I'd like) I find myself needing to figure out where a particular change originated (which development branch). In this case I have to spend a considerable amount of time playing detective to trace a change backwards through 2-3 merges. Am I missing an easy way to do this?

  • .htaccess mod_rewrite URL query

    - by 1001001
    I was hoping someone could help me out. I'm building a CRM application and need help modifying the .htaccess file to clean up the URLs. I've read every post regarding .htaccess and mod_rewrite and I've even tried using http://www.generateit.net/mod-rewrite/ to obtain the results with no success. Here is what I am attempting to do. Let's call the base URL www.domain.com We are using php with a mysql back-end and some jQuery and javascript In that "root" folder is my .htaccess file. I'm not sure if I need a .htaccess file in each subdirectory or if one in the root is enough. We have several actual directories of files including "crm", "sales", "finance", etc. First off we want to strip off all the ".php" extensions which I am able to do myself thanks to these posts. However, the querying of the company and contact IDs are where I am stuck. Right now if I load www.domain.com/crm/companies.php it displays all the companies in a list. If I click on one of the companies it uses javascript to call a "goto_company(x)" jQuery script that writes a form and submit that form based on the ID (x) of the company. This works fine and keeps the links clean as all the end user sees is www.domain.com/crm/company.php. However you can't navigate directly to a company. So we added a few lines in PHP to see if the POST is null and try a GET instead allowing us to do www.domain.com/crm/company.php?companyID=40 which displays company #40 out of the database. I need to rewrite this link, and all other associated links to www.domain.com/crm/company/40 I've tried everything and nothing seems to work. Keep in mind that I need to do this for "contacts" and also on the sales portion of the app will need to do something for "deals". To summarize here's what I am looking to do: Change www.domain.com/crm/dash.php to www.domain.com/crm/dash Change www.domain.com/crm/company.php?companyID=40 to www.domain.com/crm/company/40 Change www.domain.com/crm/contact.php?contactID=27 to www.domain.com/crm/contact/27 Change www.domain.com/sales/dash.php to www.domain.com/sales/dash Change www.domain.com/sales/deal.php?dealID=6 to www.domain.com/sales/deal/6 (40, 27, and 6 are just arbitrary numbers as examples) Just for reference, when I used the generateit.net/mod-rewrite site using www.domain.com/crm/company.php?companyID=40 as an example, here is what it told me to put in my .htaccess file: Options +FollowSymLinks RewriteEngine On RewriteRule ^crm/company/([^/]*)$ /crm/company.php?companyID=$1 [L] Needless to say that didn't work.

  • Need Help Loading and Manipulating Bitmap Data

    - by Dave
    Using VB6, I need to load a bitmap image and subsequently manipulate some of its data - specifically, I want to rotate a section within the image, and in the end keep the image intact with the rotated section. How do I (1) find out where an image gets loaded into memory (a physical address), and (2) in what format is it stored, a 1-D array, 2-D array, or what? Maybe you can even suggest a better way to do this. Thanks.

  • Not sure what happens to my apps objects when using NSURLSession in background - what state is my app in?

    - by Avner Barr
    More of a general question - I don't understand the workings of NSURLSession when using it in "background session mode". I will supply some simple contrived example code. I have a database which holds objects - such that portions of this data can be uploaded to a remote server. It is important to know which data/objects were uploaded in order to accurately display information to the user. It is also important to be able to upload to the server in a background task because the app can be killed at any point. for instance a simple profile picture object: @interface ProfilePicture : NSObject @property int userId; @property UIImage *profilePicture; @property BOOL successfullyUploaded; // we want to know if the image was uploaded to out server - this could also be a property that is queryable but lets assume this is attached to this object @end Now Lets say I want to upload the profile picture to a remote server - I could do something like: @implementation ProfilePictureUploader -(void)uploadProfilePicture:(ProfilePicture *)profilePicture completion:(void(^)(BOOL successInUploading))completion { NSUrlSession *uploadImageSession = ..... // code to setup uploading the image - and calling the completion handler; [uploadImageSession resume]; } @end Now somewhere else in my code I want to upload the profile picture - and if it was successful update the UI and the database that this action happened: ProfilePicture *aNewProfilePicture = ...; aNewProfilePicture.profilePicture = aImage; aNewProfilePicture.userId = 123; aNewProfilePicture.successfullyUploaded = NO; // write the change to disk [MyDatabase write:aNewProfilePicture]; // upload the image to the server ProfilePictureUploader *uploader = [ProfilePictureUploader ....]; [uploader uploadProfilePicture:aNewProfilePicture completion:^(BOOL successInUploading) { if (successInUploading) { // persist the change to my db. aNewProfilePicture.successfullyUploaded = YES; [Mydase update:aNewProfilePicture]; // persist the change } }]; Now obviously if my app is running then this "ProfilePicture" object is successfully uploaded and all is well - the database object has its own internal workings with data structures/caches and what not. All callbacks that may exist are maintained and the app state is straightforward. But I'm not clear what happens if the app "dies" at some point during the upload. It seems that any callbacks/notifications are dead. According to the API documentation- the uploading is handled by a separate process. Therefor the upload will continue and my app will be awakened at some point in the future to handle completion. But the object "aNewProfilePicture" is non existant at that point and all callbacks/objects are gone. I don't understand what context exists at this point. How am I supposed to ensure consistency in my DB and UI (For instance update the "successfullyUploaded" property for that user)? Do I need to re-work everything touching the DB or UI to correspond with the new API and work in a context free environment?
