Hi,
I would like to know if C++ provides any API (not third-party) for pattern matching using regular expressions like Java does. If it doesn't, whats the best way to do it ?
Thanks.
I have a string which contains a contiguous chunk of digits and then a contiguous chunk of characters. I need to split them into two parts (one integer part, and one string).
I tried using String.split("\D", 1), but it is eating up first character.
I checked all the String API and didn't find a suitable method.
Is there any method for doing this thing?
We had a process that crashed while trying to manipulate an expected mysql record set, running the offending query from the mysql cli showed the following.
mysql SELECT ...;
ERROR 1030: Got error 127 from table handler
Is there a way to easily recreate this condition so we can validate our fix ? (production DB was already repaired).
My web-app has to deliver db-generated content by email. The HTML need not include javascript but _does have to include images and CSS.
It's a safe bet that most users will be viewing this in Outlook. Are general guidelines different for html destined for email vs. IE?
I'm trying to figure out how to instantiate a case class object with reflection. Is there any support for this? The closest I've come is looking at scala.reflect.Invocation, but this seems more for executing methods that are a part of an object.
case class MyClass(id:Long, name:String)
def instantiate[T](className:String)(args:Any*) : T = { //your code here }
Is close to the API I'm looking for.
Any help would be appreciated.
Hi,
Is it possible for entering values into dropdown and saving that values to DB? If yes please help me by giving the code for that. Thanks in advance
I can find how to define columns only when doing migrations.
However i do not need to migrate my model.
I want to work with it "virtually".
Does AR read columns data only from db?
Any way to define columns like in DataMapper?
class Post
include DataMapper::Resource
property :id, Serial
property :title, String
property :published, Boolean
end
Now i can play with my model without migrations/connections.
I know that google goggles will translate a picture to text. What I want to do is allow the user to take a picture (no problem), translate that picture to text(?) and then do some processing on the text (no problem).
Is there any API on android that allows this? or is there any way to programtically communicate with google goggles? I would hate to have the user use goggles then select the saved file with my app.....
I'm a big fan of JGraphT, a Java library for graphs. Could anyone recommend a similar Java library for trees? Preferrably FOSS.
What I need is a good API, preferrably typesafe with generics which allows modelling different kinds of trees (with some user data attached to verticies/edges) and run different algorithms and operations on these trees. For instance, traverse or balance.
At the moment I'm not interested in visualization of trees.
Adobe Air's (read: Flex) mx:HTML component uses WebKit to render webpages. As such, does anyone know of a way to tweak WebKit's settings via the Air application (or a Flex API)? For example, I'd like to set WebKit's "enable-private-browsing" setting from "false" to "true".
I want this SQL query to be written in rails controller using find
select id,name from questions where id not in (select question_id from levels_questions where level_id=15)
How will I do this?I am using Rails framework and MySQL db
thanks in advance.
Ok, So I have to generate very complex reports from my DB.
If I am to do it with SQL the query themselves will be complex, and I will have to do some more manipulation on the results later, code level.
How do libraries like Jasper Reports/ Crystal Reports and friends save me time when developing such reports?
What will they give me?
Hi,
What I want to achieve is after loading my object from the database, to generate a code that will give me a block which initializes my object based on its current values so that I can use this code-block in my unit tests again and again without loading it from Db anymore.
Is there any tool around to achieve such a goal for VS?
thanks

Would it be possible to integrate Python (and/or Perl) and Ruby? I've looked at http://www.goto.info.waseda.ac.jp/~fukusima/ruby/python/doc/ and http://code.google.com/p/ruby-perl/ , but they both seem rather outdated.
Has someone generated a Ruby interface for Python's C API?
Using jquery's $.ajax function, I'm not able to parse the results. For example, I used it like this
$.ajax({
url : "http://api.twitter.com/1/users/show.json?screen_name=techcrunch",
dataType : "json",
success : function(data)
{
// parse the JSON here
},
error : function()
{
alert("Failure!");
},
});
This doesn't work. Do I need a callback function?
I am using mysql_fetch_assoc($query), one of the bit field returns out to be , which is supposedly to be true.
The problem is that I also need to output this to xml and it's an illegal xml character.
the charset for the db table is utf-8. why does this happen?
I have a string of HTML stored in a database. Unfortunately it contains characters such as ®
I want to replace these characters by their HTML equivalent, either in the DB itself or using a Find Replace in my Python / Django code.
Any suggestions on how I can do this?
How do I parse an xml document as a stream using Scala?
I've used the Stax API in java to accomplish this, but I'd like to know if there is a "scala" way to do this.
Hi All,
I have a observable collection of viewmodel objects. How can I subscribe to the Property Changed event of each view model in my collection as they are created and track which ones have been changed, so that I can updated them to my database.
List<DomainObject> objectsToSave = new List<DomainObject>();
foreach (Test val in dirtyObjs)
{
objectsToSave.AddRange(val.GetObjectsToSave());
}
//DB changes
bool saveSucceeded = DataServices.SaveMultiple(objectsToSave);
I'm really looking for something very similar to the way SO is setup where a few different kinds of things can be voted on (questions AND answers). What kind of DB schema, generally, could I use to support voting on many different kinds of objects?
Would I have a single Vote table that would have references to other objects in the database? Or do I have to have or should have a separate vote table for each of the objects I would like to vote on.
