Is there a place to set header and library path for ALL projects in VC2010 express?
When i set them they seem to only apply to a single project (eg i have to set them everytime i start a new project).
I have a java primitive type at hand:
Class c = int.class; // or long.class, or boolean.class
I'd like to get a 'default value' for this class - specifically the value is assigned to fields of this type if they are not initialized. E.g., '0' for a number, 'false' for a boolean.
Is there a generic way to do this? I tried
c.newInstance()
But I'm getting an InstantiationException, and not a default instance.
Let's say I've got:
Dim los1 as New List(Of String)
los1.Add("Some value")
Dim los2 as New List(Of String)
los2.Add("More values")
What would be the most efficient way to combine the two into a single List(Of String)?
Edit: While I'm loving the solutions everyone has provided so far, I probably should also mention I'm stuck using the .NET 2.0 framework. Any other suggestions?
Most of the languages like C++ when writing into a file, put an EOF character even if we miss to write statements like :
filestream.close
However is there any way, we can put the EOF character according to our requirement, in C++, for an instance.
Or any other method we may use apart from using the functions provided in C++.
If you need to ask more of information then kindly do give a comment.
Thanks in advance.
I am using Netbeans 6.8
The problem is that the projects explorer (that displays all the projects and their contents) displays each package as a node. For instance, if there is package hierarchy like this;
com.mycompany.myproject.package1.package1.1
then it displays 5 nodes for the five packages which is very disturbing while development.
Is there any way by which I can configure it(Netbeans) so that it groups all the subpackages of a package under one node and displays the subpackages only when I expand the package node?
I use the DAO method Execute to delete some records. If this fails this is clear by checking RecordsAffected (it will be 0). But is it possible to get the error message (for instance, to log or to show to the user)? I've try to delete the records by hand in the Table grid I get a clear dialog message, e.g. "The record cannot be deleted or changed because tabel x includes related records".
Hi,
I've seen iphone related open source library which says something like,
"You need 4.0+ iOS build environment but the code will run on 3.0+ iOS device."
I wonder how those two requirements can differ and how can I tell a minimum 'device' iOS version which a certain api would need.
For instance I want to use UIGestureRecognizer but the apple doc says it's 3.2+, but I want my app run on 3.12+.
Is there a difference between build os requirement and device os requirement to run an app?
Thank you
$('#customerAddress').text().replace(/\xA0/,"").replace(/\s+/," ");
Going after the value in a span (id=customerAddress) and I'd like to reduce all sections of whitespace to a single whitespace. The /\s+/ whould work except this app gets some character 160's between street address and state/zip
What is a better way to write this? this does not currently work.
I'm trying to create a program in C# that lists the content of a library in Windows Media Center (for instance the video library).
Is this possible using the Windows Media Center SDK, without having to create it as an addin for WMC, but as an "external" program, running on the same machine as WMC?
I've had a big problem in some library code, which I've pinned down to a single statement:
System.out.println((String) null);
Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException.
In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?
Hello,
I have an object of CalendarEntry
I know that http://www.google.com/calendar/feeds/[email protected]/allcalendars/full is the feed url of all calendars
but how I can get this feed url from CalendarEntry instance?
Because I wanna post a new entry in a specified calendar and I need this url.
Thanks!
Hi,
I guess it has to do something with string being a reference type but I dont get why simply string.Replace("X","Y") does not work?
Why I need to do `string A=stringB.Replace("X","Y")
I thought it is just a method to be done on specified instance? Thanks for explanation
EDIT: Thank you so far. I extend my question Why "b+="FFF"works but the b.replace is not?
I have a simple two vector dataframe (length=30) that looks something like this:
> mDF
Param1 w.IL.L
1 AuZgFw 0.5
2 AuZfFw 2
3 AuZgVw 74.3
4 AuZfVw 20.52
5 AuTgIL 80.9
6 AuTfIL 193.3
7 AuCgFL 0.2
8 ...
I'd like to use each of the rows to form 30 single value numeric vectors with the name of the vector taken from mDF$Param1, so that:
> AuZgFw
[1] 0.5
etc
I've tried melting and casting, but I suspect there may be an easier way??
Thanks in advance

I have an SQL query that has an alias in the SELECT statement
SELECT
CONCAT(YEAR(r.Date),_utf8'-',_utf8'Q',QUARTER(r.Date)) AS 'QuarterYear'
Later, I want to refer to this in my group by statement.
I'm a little confused...should I wrap this with backticks, single quote or just leave it unwrapped int he group by
GROUP BY
`QuarterYear `
or should I do this?:
GROUP BY
'QuarterYear'
or just this?:
GROUP BY
QuarterYear
I just wrote a custom progress bar, it's single buffered and will remain so. How many frames per second are desirable for something like this? I don't want to waste too much CPU updating the screen unnecessarily.
I am writing a networking application using the java.nio api. My plan is to perform I/O on one thread, and handle events on another. To do this though, I need to synchronize reading/writing so that a race condition is never met.
Bearing in mind that I need to handle thousands of connections concurrently, is synchronization worth it, or should I use a single thread for I/O and event handling?
Hi guys, I'm studying MEF and I'm not able to resolve a problem.
I have a main application, called MainMEF, and a simple module, called SimpleModule. This one consists of a single UserControl which is loaded dinamically.
When MainMEF starts up, I would be able to pass to the module a reference to main application contained into MainMEF.
How could I fix this? Thanks in advance.
Hello: Does anyone have a solution to convert an acts_as_tree model to json that includes all its nodes? I trued using :include=:children, but that only goes down to one single level. Any idea how to iterate the whole tree?
Hi,
i would like to set the date format of all the dates in my web application in a central location.
i mean if the website is opened in USA it will have a format such as
3/19/2010 (March/19/2010)
while in Italy will be
19/3/2010 (19/March/2010)
i am no really concerned with how to locate the users but indeed on how to set the different date format for the whole application in one single location in c#.NET
thanks
There are two arrays with equivalent size. How to decide whether these two arrays contain the same set of elements, but the orders of these elements in the respective arrays are different.
For instance.
A = [a, b, c]
B= [b, c, a]
For instance this code:
function stuff() {
this.onlyMethod = function () {
return something;
}
}
// some error is thrown
stuff().nonExistant();
Is there a way to do something like PHP's __call as a fallback from inside the object?
function stuff() {
this.onlyMethod = function () {
return something;
}
this.__call__ = function (name, params) {
alert(name + " can't be called.");
}
}
// would then raise the alert "nonExistant can't be called".
stuff().nonExistant();
Say that I have a table with one column named CustomerId.
The example of the instance of this table is :
CustomerId
14
12
11
204
14
204
I want to write a query that counts the number of occurences of customer IDs.
At the end, I would like to have a result like this :
CustomerId NumberOfOccurences
14 2
12 1
11 1
204 2
14 1
I cannot think of a way to do this.
Hi, I have a structs action object instance that loads a variable from a properties file.I want it to happen only the first time the action is called, so in further executions its read from memory. Any hints ? Thanks.
Is there a way to stop other subs from running while in a separate sub.
for instance say your in the sub
CreateNumber()
and the subs are setup like
CreateNumber()
AddNumber()
DeleteNumber()
Is there a way to be in CreateNumber() and call a function to stop AddNumber from running after creaetNumber() is finished? i just want my program to sit there to wait for an event to happen.
Hey,
I'm looking for a way to use something similar to link_to_unless_current but for sub URLs, so for instance for both these URLs:
/entity_name/
/entity_name/123
it will not result as a link. How can I achieve that in Rails?
