For instance, if I have:
C:\42\main.py
and
C:\42\info.txt
and I want to read info.txt from main.py, I have to input "C:\42\info.txt" instad of just "info.txt".
Is it supposed to be like that?
If not, how can I fix it?
What does "object affine" mean? For instance, there are object affine thread pools. While I understand both thread pools and affine transformations in math, I can't think of an association between them.
Hi,
In the constructor of an object i need to create a WPF mediaElement object:
m_videoMedia = new MediaElement();
but the class can also be instantiated from a other thread so i need to use
Dispatcher.Invoke(DispatcherPriority.Normal,
(Action)(() => { m_videoMedia = new MediaElement(); }));
But how can I get the right dispatcher instance in that constructor :s
How can i write 'one bit' into a file stream or file structure each time? is it possible to write to a queue and then flush it ? is it possible with c# or java?
this was needed when i try to implement an instance of Huffman codding. i can't write bits into files. so write them to a bitset and then (when compression was completed) write 8-bit piece of it each time (exclude last one).
I have an application which uses UDP connection, now when i try to run the app more than once its throwing me an exception
java.net.BindException: Address already in use: Cannot bind
but in my another app, which uses tcp connection, i can open two instance of the same app and its working fine. why this error only with UDP connection?
I have a Queue of items I want to process in a thread, and any instance of a class can add items to the Queue to be processed.
My idea for doing this is to have a static Thread in the class that processes the items, the only problem is that I don't know where to start this thread, since I can't start it in its initialization.
Is there a way I can start a static thread? Or should I be changing the architecture completely?
Certain settings in the Settings app allow you to add rows to tables within the interface (for instance, within the Mail settings you can add accounts)
Is this done with a settings bundle? How is this done?
I have the following 2 macros:
#define SCOPED_ENUM_HEADER(NAME) struct NAME{ enum _NAME{
#define SCOPED_ENUM_FOOTER(NAME) };}; typedef NAME::_NAME NAMEtype;
Only the first instance of NAME get replaced by the passed NAME. What's wrong with it?
Is is to be used in such a way:
SCOPED_ENUM_HEADER(LOGLEVEL)
UNSET,
FILE,
SCREEN
SCOPED_ENUM_FOOTER(LOGLEVEL)
Thanks you
Hello,
I am trying to use this query to return every instance where the variable $d['userID'] is equal to the User ID in a separate table, and then echo the username tied to that user ID.
Here's what I have so far:
$uid = $d['userID'];
$result = mysql_query("SELECT u.username
FROM users u
LEFT JOIN comments c
ON c.userID = u.id
WHERE u.id = $uid;")$row = mysql_fetch_assoc($result);
echo $row['username'];
I need a way to see all the defined variables of the current PHP instance.
By currently defined I mean all the globals, all the local to THIS scope and all the locals to other scopes.
Is there something built in?
I have a table with anniversary dates. I want a query that returns me rows of anniversaries coming up in the next 10 days. For instance:
birthdate
---------
1965-10-10
1982-05-25
SELECT birthdate FROM Anniversaries WHERE mystical_magical_mumbo_jumbo <= 10
+------------+
| birthdate |
+------------+
| 1982-05-25 |
+------------+
1 row in set (0.01 sec)
I'd like to keep the query in the form x <= 10, because I'll use that number 10 in other parts of the query, and if I set it to a variable, I can change it once everywhere by changing the variable, and not have to re-write the query.
Hi,
I am trying to make an exit button for my application. Anyhow I am able to track all the instance of activity in my application and then finish them all. But still some activity remain alive in some cases. Dont know how. Is there any method to kill a particular application in android. Or any other way can I exit from my application.
Thanks
When creating a new instance of a MyClass as an argument to a function like so:
class MyClass
{
MyClass(int a);
};
myFunction(MyClass(42));
does the standard make any grantees on the timing of the destructor?
Specifically, can I assume that the it is going to be called before the next statement after the call to myFunction() ?
Hi everyone,
I took my first step today on working with cloud servers and chosed Amazon EC2 for this project. Since I am a bit of a newcomer on this, I didn't fully understand their pricing:
What happens when a instance is idling
with no connections being made. Does
it still cost us money?
It would be sad to have instances idling and costing us money when we do not use them...
Thanks a lot!
Hello, could some one recommend a way to get page name from a url using JavaScript?
For instance if I have http://www.cnn.com/news/1234/news.html?a=1&b=2&c=3
I just need to get "news.html" string
Thanks!
This is useful if you are trying to create class methods metaprogramatically:
def self.create_methods(method_name)
# To create instance methods:
define_method method_name do
...
end
# To create class methods that refer to the args on create_methods:
???
end
My answer to follow...
Hello,
I'd like to know if the executing thread is the one that created a given control instance (to prevent cross-thread if it's not).
Is that possible ?
Thx.
I am willing to build an email application which runs on the server side.
Not being familiar with any particular server I wonder if I can get some recommendations based on experience.
I have seen many great startups which built some neat apps on the email platform (for instance, friendfeed's notification mechanism, or surely posterous which mail is at the heart of their business logic), and wonder about which mail server have they found easy to learn and integrate with.
PS:
MS Exchange or any other not open-source are not an option
Must run on linux
I have a column of states, and, depending on the query, I want to order by results by a particular state, then by id (Asc or Desc, depending). For instance, I might want to show all rows with state "HI", sorted by ID desc, and then all the other rows, sorted by id desc.
I was hoping I could do this in one query, rather than getting all my favored state results, and then getting the rest. Can I?
If I have a template definition like the one below, can someone provide a code sample for how I would actually instantiate an instance of this with two of my own classes?
template <class T1, class T2>
class LookUpTable {
public:
LookUpTable();
void set(Tl x, T2* y);
T2* get(Tl x);
};
Thanks.
For example, I open a file called "abc.txt". Now I want to search for all occurrences of "he is" and "first" simultaneously. I want to be able to do a search forward i.e. Ctrl-s and I'll reach the next instance of either of the two search strings.
I would like to have in my Flex application the ability to post objects (for instance images or text items) where user can drag/drop for absolute positioning on the screen, resize it and rotate it (although not high priority). I'm wondering if there is a library that would do so out of the box or do you recommend implementing my own?
