My json object looks like:
User { ID: 234, name: 'john', ..);
I want to build a string of all the ID's.
How can I do this? is there a more elegant way than below?
var ids = '';
for(int x = 0; x < json.length; x++)
{
ids += json[x].Id + ",";
}
// strip trailing id

Does anybody have an example of working with database using Visual C++ and OLEDB? What should I include on top of my code?
I have searched the internet and most examples are using C# or VB. Examples written by C++ are usually not complete.
I really appreciate your help.
Best,
Shadi.

I have an object (Contacts) which has two has_many relationships: Campaign and Company
When I am in the Campaign view, I want to add a Contact.
But without a Company_Id, Controller says cannot find company_id (which needs to be there if I add a Contact through the Company).
What should I do?
Hi,
I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor:
def p = toProxy(1)
assert p == 1
assert p * 2 == 2
assert p.underlying == 1
def p2 = toProxy(objWithMethodFoo)
p2.foo()
p2.underlying.foo()
I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.
Doctrine Automatically creates indexes on columns that are used to define object relations,
For example
user: id, name
message: id, sender_id, receiver_id, message
if I define relationship between message and user in a way that message has one Sender and has one Receiver, doctrine will automatically index sender_id and receiver_id fields when I generate sql from model. I would like to disable index on sender, because I manually create index with sender_id and receiver id together. How can I disable auto generated index?
I am a rank beginner in C#. I am currently using this code:
objGraphics.Clear(SystemColors.Control);
What I want to do is Clear this object to black (or some other RGB color), and I'm stumped as to how to replace the SystemColors.Control with, preferably, an RGB color spec. I'd probably want to clear to black most of the time. Any help will be much appreciated!
I've made 2 apps, App A and App B. App A's sole purpose is to allow users to sign up and App B's purpose is to take select users from App A email them. Since App A & B were created independently & are hosted in 2 separate Heroku instances, how can App B access the users database in App A? Is there a way to push certain relevant rows from App A to App B?
I read some tutorials on how to read data from a database.properties file- which basically stored key-value pairs.
What i want to know is, in which folder should I place this file? Is it in the root (ie "src") or within a package... And how do I access this file, if it is placed in "src"- my code will be within a package (and the package's directory will be under src)- so how do I access the properties file, which is in "src", from a class within a package?
Hi there,
I'm trying to find information on different ways to traverse an object tree in python.

Thanks so much

I can successfully symbolicate my function names using Shark profiler but not with the Object Allocations instrument.à

Do you know of any good doc on Excel PivotTables object model ?
I have read "Excel 2007 Programmers reference", googled a bit, and found small bits here and there, but nothing global, coherent and complete.
Preferably for version < 2007, so I keep upwards compatibility when developing.
Thanks !
This is regarding SQL server 2008 management studio..
I connect to different environment DB and every time I launch the Sql management console, I have to sign up every time to get those connections back in object explorer. Is there a way I could persist the connection so I don't have to login every time to different environments?
Hi,
Every time when I change some values in form controls, I need to set a property of an object or vice versa. Instead of writing some methods for each control, I want a general solution for GUI elements. I do not use WPF but only C# 3.0.
Any suggestions?
Thanks.
This line:
used_emails = [row.email for row
in db.execute(select([halo4.c.email], halo4.c.email!=''))]
Returns:
['[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]']
I use this to find a match:
if recipient in used_emails:
If it finds a match I need to pull another field (halo4.c.code) from the database in the same row. Any suggestions on how to do this?

I've got a 'MyDataTable' class that inherits from System.Data.DataTable
I've implemented ISerializable in my class and have a 'Public Overrides Sub GetObjectData...'
But when I try to serialize the an object of 'MyDataTable' I get an error saying that 'MyDataTable' is not marked as serializable.
If I used a DataTable instead - my code serializes correctly.
If I add a serializable attribute to the 'MyDataTable' class - it serializes correctly, but I'm told that is unnecessary if I implement ISerializable.
Can someone point me in the right direction?
