Eclipse java - how to add full line with double quotes
I'm programming in Eclipse and i have a SQL script that got multiple lines:
SELECT * FROM
.... (bla bla)
... (bla bla )..
... (bla bla bla bla)
I have to add the double quotes like this:
" SELECT * FROM "
+ ".... (bla bla) "
+ "... (bla bla ).."
+ "... (bla bla bla bla) "
Is there any SHORTCUT to do this in Eclipse?

How to export 0.5 million rows to excel/csv (performance issue)?
How to export 0.5 million rows to excel/csv (performance issue)?
Currently we are using NPOI for exporting some large data to
excel(environment--asp.net mvc-4.0 ). Its taking us around a minute to
export 30000 rows to excel. Now the requirement has changed and we want
500000 which is more then 10 times the current rows. NPOI serializer has
some limitations which is having drastic performance
issue..http://npoi.codeplex.com/discussions/443655 ...So after trying lot
of alternatives we decided that we will export this huge chunk of data to
csv file. Before starting with this code change I wanted to get an expert
opinion on how to handle this scenario where you have to deal with such a
massive number of rows export... Is exporting to CSV a better option???
Can any one point out a code sample or an article that has a solution to
data export to csv/excel for more the 0.5 million rows within a 1 min
timeframe..

curve fitting using multiple starting points for every variable
curve fitting using multiple starting points for every variable
Given a random parametric function with n parameters used to fit
datapoints. You define you're parametric function by heigthmodel You're n
startingvalues are defined as initial values For the fitting you use
lsqcurvefit(heigthmodel,initialvalues,...
Is there a way you can give more then one startingvalue for every
parameter. So that you add another string of startingvalues and the model
will start from both startingvalues and will return the best result?
I've already setup something like this:
Heightmodel = ....
Startingvalues = a1 a2 a3 a4 a5
Startingvalues = b1 b2 b3 b4 b5
options=optimoptions(numberofvariables,2) % based on the TypicalX function.
lsqcurvefit(heightmodel,startingvalues,...,options)
It would be interesting to know if I could make this work and if so if I
could add more startingvalues. So I will have p strings of startingvalues
and numberofvariables,p
Also is there a way to present these startingvalues in a matrix form? So
that for the first variable the fitting can choose to start from both a1
or b1, for the second variable from both a2 or b2? ...

Hide a folder from file sharing
Hide a folder from file sharing
I have an app that is link with pdf documents. If the user open a pdf
document in a browser, my app will be listed in the Open in... menu. This
file is downloaded automatically in a folder called Inbox, which I didn't
create, located in the Documents directory. However, I don't want this
folder to appear in iTunes when file sharing is enabled. I don't want to
allow the user to delete or modify neither the folder nor its contents.
Is there any way I can change the properties of this folder to hide it
from iTunes?

however I am receiving this error btstart cannot be resolved or is not a
