Hello,
I have got four classes A, B, C and D.
Class A has a member b of class
B.
Class B has a member c of class C.
A has a member D* dpointer;
This hierarchy has to be preserved (in fact this is a GUI with app, window, panel as A, B and C).
Now B and C must use a method from *dpointer.
Is there something more elegant than giving dpointer as a member of B and C ? Is it bad ?
Hello,
I want to set the size of a JFrame such that the contentPane is the desired size. JFrame.setSize() doesn't take the window decorations into account, so the contentPane is slightly too small. The size of the window decorations are platform and theme specific, so it's bad news to try to manually account for them.
JFrame.getContentPane().setSize() fails because it's managed.
Ideas?
Thanks!
I've seen a lot this kind of code recently :
if ($foo = $bar->getFoo())
{
baz($foo);
}
Is this considered good or bad practice ?
For example, Netbeans IDE give a notice if you use this kind of code :
Possible accidental assignment,
assignments in conditions should be
avoided
What do you think ?
Hi,
Today I got this question for which I think I answered very bad. I said stream is a data that flows and reader is a technique where we read from that is a static data. I know this is an awful answer, so please provide me the crisp difference and definitions between these two with example in Java.
Thanks.
Using bash, I have a list of strings that I want to use to replace an int. Here's an example:
day1=Monday
day2=Tuesday
day3=Wednesday
day4=Thursday
day5=Friday
day6=Saturday
day7=Sunday
If I have an int, $dow, to represent the day of the week, how do I print the actual string? I tried this:
echo ${day`echo $dow`}
but get error of "bad substitution". How do I make this work? Note: I can change the $day variables to a list or something.
I have already a site with a single homepage index.php which accepts 2 parameters like
http://mydomain.com/index.php?param1=something¶m2=somethingelse
param2 can be optional
I want to install wordpress on the root directory, except for index.php and the above url, I want wordpress to show the blog pages.
How to do that either in PHP and/or htaccess ? (I'm very bad at htaccess so I prefer php).
Hi,
Is sequential coupling (http://en.wikipedia.org/wiki/Sequential_coupling) really a bad thing in code?
Although it's an anti-pattern, the only risk I see is calling methods in the wrong order but documentation of an API/class library with this anti-pattern should take care of that. What other problems are there from code which is sequential? Also, this pattern could easily be fixed by using a facade it seems.
Thanks
I am fighting to keep the use of stored procedures in our company. There are a few people who say they are bad and we should not use them. We are using DB2 on the i-series.
Please help in my argument to keep stored procedures alive in my company.
I just spent some time reading http://stackoverflow.com/questions/2768248/is-md5-really-that-bad (I highly recommend!).
In it, it talks about hash collisions. Maybe I'm missing something here, but can't you just encrypt your password using, say, MD5 and then, say, SHA-1 (or any other, doesn't matter.) Wouldn't this increase the processing power required to brute-force the hash and reduce the possibility of collision?
Very quick question about programming practices here:
I've always used echo() to output HTML code to the user as soon as it was generated, and used ob_start() at the same time to be able to output headers later in the code. Recently, I was made aware that this is bad programming practice and I should be saving HTML output until the end.
Is there a reason for this? What is it, and why isn't output buffering a good alternative?
Thanks!
I read a lot of blogs and see people all the time talking about bad things in the java programming language; a lot of them are about annotations and generics that were added to the language in 1.5 release. What are the things in the language or the API that you don't like or would design differently?
I merged the wrong way between two branches. I then ran the following:
git reset --hard HEAD^
I am now back at the previous commit (which is where I want to be). Was that the correct thing to do?
The bad commit is still in the repository, is that okay or should I do something else to remove it from the repository?
I have not pushed or committed anything else yet.
Hello,
A class A possesses an instance c of a class C. Another class B has to modify c through C::setBlah(); method.
Is it bad to create an accessor C getC(); in A and then use A.getC().setBlah() ?
Or should I create a method A::setBlah(); that would call C::setBlah(); ? Isn't it annoying if there are several methods like that ?
I just wonder is there's any way to fire any event via IE's event-triggering implementation - fireEvent. I've tried to use it but failed with all event except click.
The only reason i've get interested with this issue it curiousity, thus, any answers like "just do not trigger events, it is a bad idea" - all such answers would be considered, well...not full)))
thanks in advance
I ran this using MySql and it appears to not like TEXT. With SQL server i use nvarchar(max) What should i use in MySQL? In other tables some fields will be descriptions and may be long so ATM i am thinking fixed length is bad.
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;
Hi,
If I am developing a class and I don't know who are going to use it. What's the drawback if I declare all the member functions virtual? It's a good design or bad design?
Thanks so much!

Hello.
In my program, I need to make use of an ElementTree object in various functions in my program.
More specifically, I am doing this:
tree = etree.parse('somefile.xml')
I am passing this tree around in my program.
I was wondering whether this is a good approach, or can I do this:
Create a global tree (I come from a
C++ background and I know global is
bad)
Create the tree again wherever required.
Or is my approach ok?
I have a technical interview on Monday and they were kind enough to give me a heads-up to brush up on my basic algorithms. It's been years since I looked at that kind of stuff and I'm pretty weak on it to begin with so I generally have a bad feeling about this. What's the best way to review the basics and get some practice in before Monday?
I tried the following && conditional for my if statement and I get a "bad range" error:
<% if (from_today(contact, call.days) == 0..7) && (show_status(contact, call) == 'no status') %>
Why and how can I fix it? The only other way I could do it was to have a second nested if statement and break it apart...not pretty :(
i wrote a program that needs to continuously run. but since im a bad programmer it crashes every so often. is there a way to have another program watch it and restart it when it crashes?
what java method takes an int and returns +1 or -1? the criteria for this is weather or not the int is positive or negative. I looked through the documentation but i'm bad at reading it and i can't find it. I know i've seen it somewhere though.
$a = "sad day
Good day
May be Bad Day
";
$a=~s/\w+ \w+/_/gm;
print $a;
I am trying to subsitue with _ all spaces between words .
But its not working . What is wrong with that.
Hi,
I have a simple question. Is it okay to use array without single or double quotion like $array[key]? I thought it is bad because PHP look for constant first if I don't use single or doulbe quotion. One of my colleagues told me that it does not matter.
WHat do you guys think?
