In C static can mean either a local variable or a global function/variable without external linkage. In C++ it can also mean a per-class member variable or member function.
Is there any reference to how it happened that the static keyword that seems totally irrelevant to lack of external linkage is used to denote lack of external linkage?
Hello;
Why can't I start a line using a parenthesis followed by the keyword new?? For example:
(New <custom_obj>).foo(var)
In that case is obvious that I'm trying to avoid creating a named instance of the the <custom_obj> because I know that I'll only be using it at that sentence.
Note that actually creating a named instance is not a problem for me... I just wanna know the reason why this is not possible.
I'm using Google prettify for syntax highlighting and I'd like to modify the colors to match my website theme, but I don't understand some of the abbreviations from these:
str = string
atw
kwd = keyword
tag = tag
com = comment
typ = type?
atn
dec = declaration?
lit
pun = punctuation? like colons, braces?
pln
prettyprint
I have a stored procedure that will return xml. I have delared a variable of type xml and trying to execute the following code
declare @v xml

whereas id is returned by another query. now it keeps compalinng about the following error
Incorrect syntax near the keyword 'execute'.
for my project i need to access entire pages(100) of google at a time for a particular keyword.I used 'for' loop for accessing pages in url written in my c# code.But it is taking more time to access.Some times it showing HttpRequest error.Any way to increase the speed?
I have a class (Class B) that inherits another class (Class A) that contains virtual methods.
Mistakenly, I omitted the override keyword when declaring a (supposed to be) overriding method in Class B.
Class A
public class ClassA{
public virtual void TestMethod(){
}
}
Class B
public class ClassB : ClassA{
public void TestMethod(){
}
}
The code compiled without a problem. Can anyone explain why?
The line cmd.ExecuteNonQuery();
cmd.CommandText
CREATE TRIGGER subscription_trig_0 ON subscription
AFTER INSERT AS
UPDATE user_data
SET msg_count = msg_count + 1
FROM user_data
JOIN INSERTED ON user_data.id = INSERTED.recipient;
The exception:
Incorrect syntax near the keyword 'TRIGGER'.
Then using VS 2010, connected to the very same file (a mdf file) i run the query above and i get a success message.
Why can't i define a variable recursively in a code block?
scala> {
| val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
| }
<console>:9: error: forward reference extends over definition of value fibs
val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
^
scala> val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
fibs: Stream[Int] = Stream(1, ?)
lazy keyword solves this problem, but i can't understand why it works without a code block but throws a compilation error in a code block.
Hi,
I want to extract the status from the string untill I found a timespan. My input is something like "Something in start but not with this keyword of sure. STATUS: My Status Is Here Which can be anything but timespan 23:59:01 and so on. I want to extract the string after STATUS: untill 23:59:01 is found. How can i achieve this through regex. this 23:59:01 is a timespan and it is always in this format hh:mm:ss
Is there any existing Python library that can validate data in Excel format? Or what kind of keyword should I use to search such an open source project? Thanks.
So, I came across an interesting method signature that I don't quite understand, it went along the lines of:
void Initialize(std::vector< std::string > & param1, class SomeClassName * p);
what I don't understand is the "class" keyword being used as the parameter, why is it there? Is it necessary to specify or it is purely superficial?
I have a keyword field with a list of 5 keywords for each item. example below:
2008, Honda, Accord, Used, Car
Will MySQL full text return the item above for the following search requests?
2008 Honda Accord
Honda Accord
Used Car
If so, how well will this hold up when searching through fifty thousand plus records?
I am learning Entity framework and linq-to-entities.
It's possible to get cross values from multiple tables using JOINS (join keyword) or using the navigation fields ( associations) in which case the framework knows how to reference the cross data.
My question is what to use when?
In Resharper I edited the inspection severity of the 'use var keyword when possible' to ''do not show'.
But when I select a certain word in the code file, Resharper still shows a pencil with an Action list in the left border with the action 'use var'.
Where can I edit the actions that should be shown? I cannot find this option.
I'm trying to figure out the syntax for creating a view (or function) but only if a dependent CLR assembly exits.
I've tried both
IF EXISTS (SELECT name FROM sys.assemblies WHERE name = 'MyCLRAssembly')
begin
create view dbo.MyView as select GETDATE() as C1
end
and
IF EXISTS (SELECT name FROM sys.assemblies WHERE name = 'MyCLRAssembly')
create view dbo.MyView as select GETDATE() as C1
go
Neither work. I get
Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword
'view'.
How can this be done?
I am generating tables from classes in .NET and one problem is a class may have a field name key which is a reserved MySQL keyword. How do I escape it in a create table statement? (Note: The other problem below is text must be a fixed size to be indexed/unique)
create table if not exists misc_info (
id INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
key TEXT UNIQUE NOT NULL,
value TEXT NOT NULL)ENGINE=INNODB;
I'm working with MS Excel interop in C# and I don't understand how this particular line of code works:
var excel = new Microsoft.Office.Interop.Excel.Application();
where Microsoft.Office.Interop.Excel.Application is an INTERFACE defined as:
[Guid("000208D5-0000-0000-C000-000000000046")]
[CoClass(typeof(ApplicationClass))]
public interface Application : _Application, AppEvents_Event
{
}
I'm thinking that some magic happens when the interface is decorated with a CoClass attribute, but still how is it possible that we can create an instance of an interface with a new keyword? Shouldn't it generate a compile time error?
I want to extract some keywords out of a query string for a search application in asp.net.
I decoded the url string first, so it's plain text
I have this to start with, but I want to add a keyword group
I'd like to trim off the stuff for pure words, but not sure if that's possible
I also have a long list of possible query string value fields that I want to check against
?q=
@q=
?qs=
&qs=
We have a images folder which has about a million images in it.
We need to write a program which would fetch the image based upon a keyword that is entered by the user.
We need to match the file names while searching to find the right image.
Looking for any suggestions.
Thanks

how do i set a sql server connection to readonly? i tried googling and all i found was File Mode=Read Only but it didnt work (File Mode keyword not supported). And the reference looked sql ce specific.
No luck with sqlite Read Only=True either.
