  • How to generate an Intent that jumps into a specific short message conversation?

    - by Janusz
    I would like to create an Intent that opens the messages application in a specific conversation. If a short message notification is clicked Logcat reveals the following: INFO/ActivityManager(31909): Starting activity: Intent { act=android.intent.action.VIEW dat=content://mms-sms/conversations/3 flg=0x34000000 cmp=com.android.mms/.ui.ConversationList bnds=[0,586][600,682] } This brought me a little bit further using content://mms-sms/conversations/3 as the data starts up the messages app in the correct conversation. I now only need to find out which conversation a message belongs to.

  • Is there a way to pass a regex capture to a block in Ruby?

    - by Gordon Fontenot
    I have a hash with a regex for the key and a block for the value. Something like the following: { 'test (.+?)' => { puts $1 } } Not exactly like that, obviously, since the block is being stored as a Proc, but that's the idea. I then have a regex match later on that looks a lot like this hash.each do |pattern, action| if /#{pattern}/i.match(string) action.call end end The idea was to store the block away in the hash to make it a bit easier for me to expand upon in the future, but now the regex capture doesn't get passed to the block. Is there a way to do this cleanly that would support any number of captures I put in the regex (as in, some regex patterns may have 1 capture, others may have 3)?

  • super-space-optimized code

    - by Will
    There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

    I am using Open Source toolchain to compile my iPhone apps. So I have no Interface Builder or XCode. How would I setup the layout of widgets like UIButton, UITextView, etc. Also, how would I add an event handler to those UI widgets? Please remember that I don't have Interface Builder or XCode.

  • Use SQL to clone data in two tables that have a 1-1 relationship with each other

    - by AmoebaMan17
    Using MS SQL 2005, Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H I want to clone the data for GroupID == 1 into a new GroupID so that I result with the following: Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 5 | a | 23 | 3 6 | b | 24 | 3 7 | c | 25 | 3 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H 23 | H 24 | J 25 | K I've found some SQL clone patterns that allow me to clone data in the same table well... but as I start to deal with cloning data in two tables at the same time and then linking up the new rows correctly... that's just not something I feel like I have a good grasp of. I thought I could do some self-joins to deal with this, but I am worried in the cases where the non-key fields have the same data in multiple rows.

  • Tag suggestion (not tag autocomplete)

    - by takeshin
    AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

  • C++: Is there a way to limit access to certain methods to certain classes without exposing other pri

    - by dadads
    I have a class with a protected method Zig::punt() and I only want it to be accessible to the class "Avocado". In C++, you'll normally do this using the "friend Avocado" specifier, but this will cause all of the other variables to become accessible to "Avocado" class; I don't want this because this breaks encapsulation. Is what I want impossible, or does there already exist an obscure trick out there that I can use to achieve what I want? Or possibly alternative class design patterns that'll achieve the same thing? Thanks in advance for any ideas!

  • Efficient retrieval of lists over WebServices

    - by Chris
    I have a WCF WebService that uses LINQ and EF to connect to an SQL database. I have an ASP.NET MVC front end that collects its data from the webservice. It currently has functions such as List<Customer> GetCustomers(); As the number of customers increases massively the amount of data being passed increases also reducing efficiency. What is the best way to "page data" across WebServices etc. My current idea is to implement a crude paging system such as List<Customer> GetCustomers(int start, int length); This, however, means I would have to replicate such code for all functions returning List types. It is unfortunate that I cannot use LINQ as it would be much nicer. Does anyone have any advice or ideas of patterns to implement that would be "as nice as possible" Thanks

  • How to check that a regular expression fall into infty loop or not?

    - by Sorush Rabiee
    I'm trying to learn and hopefully use regular expression with Qt. I found that some patterns cause handler to fall into loop. for example searching \b\b in a text, never will terminate. and number of these expressions is infinite (\b\b\b,\b\b\b\b and so on). I'd like to determine and control all invalid expressions. Is there an algorithm to distinguish valid and invalid expressions? If not, how can I prevent my program from falling into an infinite loop?

  • Android: how to obtain AssetManager without reference to Context?

    - by ab11
    I have a Class that needs to obtain a reference to it's application's AssetManager. This class does not extend any sort of android UI class, so it doesn't have a getContext() method, or anything similar. Is there some sort of static Context.getCurrentApplicationContext() type of method? To clarify: my class is intended to be used like a library, for other applications. It has no associated AndroidManifest.xml or control over the context which is calling it.

  • Design ideas for

    - by ZeroVector
    I need to design and I'm looking in to using WCF to accomplish this. Basically here is how I have it: Server process: Generate list of files to transfer across multiple FTP/SFTP sites in to a queue. Client(s): Talk to server to get files to transfer. Transfer the files acquired. All the data necessary to transfer the files will be present. Once transferred successfully, notify the server to remove it from the queue. Also, make sure no other client is trying to perform the transfer. Are there are any good articles/design patterns to use? I think it sounds like a good candidate for WCF since ideally it would be load balanced against a few machines. Development will be in C#/.NET 3.5.

  • Where to store common application settings

    - by Chris
    I want to move my application settings out of XAML and into a config file. For example, ToolTips and Content strings for Buttons/CheckBoxes and Labels. Is this the job of a ResourceDictionary, or should I use the App.Config or Settings.settings file? The ToolTips and Content strings are not really per user, they are more Application wide and may change if the UI is internationalized. Thanks!

  • Django store regular expression in DB which then gets evaluated on page

    - by John
    Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks

  • Becoming better at Vim

    - by Autopulated
    I've been using Vim for quite a long time, but I'm at a level where I use insert mode most of the time, and I still use the arrow keys to move around(!). I feel like I'm not getting the best out of my lovely editor, particularly regarding navigating (especially code), copy & pasting, and doing other manipulations of existing code. (though I am quite comfortable with complicated search/replace patterns). How should I go about learning more? What resources would people recommend?
