I am making a windows service to be able to run operations on a sql server database (insert, edit, etc) and invoke Stored Procs.
However, is there a way for me to know the type of the SP? When invoking from C#, I need to knof if it is returning 1 value, or more, or none (so I can use executereader, scalar, etc)?
Thanks
I have this object which is an instance of a superclass. I want to know which subclass that object really is, so that I can decide what to do with it. There is this getClass() method but it's apparently not used for comparison issues. How can I get the sub-type of my object?
What is the correct type to use in Qt development (or C++ in general) for decimal arithmetic, i.e. the equivalent of System.Decimal struct in .Net?
Does Qt provide a built-in struct? (I can't find it in the docs, but maybe don't know where to look.)
Is there a "standard" C++ library to use?
Sorry for the multitude of iPhone Programming newb questions but..
what is the reason for having an unsigned type for something such as
- (unsigned)count
for the NSArray class.
Why not just define it as
- (int)count
?
I have a control that I purchased. When I tried to inherit from the control I get this message:
Warning: 'MyNamespace.MyFile': base type 'Mooseworks.UI.MwTextBox' is not CLS-compliant
Is there any way around this besides asking the vendor of my control to make their control CLS compliant?
I am running CentOS 5.5 x86_64 with JDK 1.6, Eclipse Galileo, and the 0.9.7 ADT is installed; however, after installation, the Android project type is not available. I have checked in the installed packages list and it is installed. Anybody encounter this problem before? Could it be due to my use of the 64-bit java VM that is installed on my system?
Hello,
how can I generate a xsd schema for a c# type (in code). There must be certainly a way, because xsd schema is generated for datacontracts in wcf.
When I type some Class, e.g. Console, then press ctrl+space and intellisense show hint "Class System.Console Represents standart input, output and error streams...."
How programmatically get this text. Can't find in google, may be I'm stupid noob.
Thanks.

public partial class Deal

public class Deal_Validation
{
[Required]
public string Title { get; set; }
public double? EstValue { set; get; }

How to validate EstValue (check if it is of type double?)
Thanks
Hi,
anyone has tried to create a symfony form filter from a class which has a field of type "date" ?
When i do it, i get this error:
500 | Internal Server Error |
Doctrine_Connection_Mysql_Exception
SQLSTATE[HY093]: Invalid parameter
number: number of bound variables does
not match number of tokens stack trace
I think the error dependens on this command:
'SELECT b.id AS b_id, b.day AS b_day FROM birthday b WHERE b.day = ? AND
b.day <= ?', array('month' = '1','day' = '2', 'year' = '2014')
but i dont know how can i solve it..
Any idea?

Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability?
As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.
I'd like to write a templated function which changes its behavior depending on template class types passed in. To do this, I'd like to determine the type passed in. For example, something like this:
template <class T>
void foo() {
if (T == int) { // Sadly, this sort of comparison doesn't work
printf("Template parameter was int\n");
} else if (T == char) {
printf("Template parameter was char\n");
}
}
Is this possible?
If i try nltxt = nllen.toString(); with nllen being int nllen = nl.getLength(); i get the error Cannot invoke toString() on the primitive type int.
I want to convert the int to string so i can display the number of entries with Log...
Why doesnt it work?
In Eclipse, the Java Method Override Indicator is the little upwards arrow next to a method in the Type Hierarchy view.
A solid arrow means a method overrides an existing method lower in the hierarchy.
What does the hollow arrow mean?
Do annotations effect either arrow?
is there a way to go from a MetaTable to an instance of an entity type so it can be queried with LINQ? What I want to do is this:
MetaTable table = GridDataSource.GetTable ();
var entity = table.GetInstanceOfEntity();
var test = (from t in entity select t).ToList();
where table.GetInstanceOfEntity() is something that I'm not sure how to implement.
Thank you
So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java?
By the way, just for reference, is this possible in C++?
Thanks.
Hello - I have an image that is currently stored in variable of type "File"..

Thanks!
Hi,
I am looking for a free/cheap SQLite editor that can handle BLOB type for Mac OS X. Basically, I just need to create a database that contains images, then load it to an iPhone app bundle. No need for fancy queries. Could someone recommend the best editor available out there for this purpose?
Thanks a lot
I have a lot of classes and want to create some kind of 'directory'.
So that I can create menus automatically.
Clicking a menu-item would then create an instance of the class and shows the window.
What I want for this is an array of System.Type where I can stuff in all the classes without instantiating them.
Though from my test and (unsuccessful) googling, this doesn't seem possible.
Any ideas?
By default certain programs format their output according to the type of the stream they write to. For example, the output of ls and ls > file looks differently. I'd like to know how this is achieved by a program. Additionally, is there a way by which we can trick such programs as if the output stream is a terminal where it actually is a file (especially when they don't have any options that affect output formatting)?
