Hi,
In class design, is it a bad habit if one method calls another method in the same class (For example, 3 methods call 1 method in the same class).
Thanks

How do I restrict a string to whitelisted characters?
// "HOW am I to understand; this is, BAD"
$str = restrictTo($str,"0-9a-z,. ");
// " am I to understand this is, "
Is there an inbuilt function in PHP that does something close? I can't formulate a regular expression for this though :(
OpenAL is such a huge thing, and the documentation doesn't tell what values are acceptable for properties. That's really bad.
I'm using the document: "OpenAL_Programmers_Guide.pdf"
Whenever I look up a property I'm left in the dark what value might be ok. For example, take AL_PITCH. What value?
Maybe someone wrote a better one? Or is there something like a wiki place with more details?
Hi!
I am well aware about error_reporting(0); & ini_set('display_errors', "Off"); to make error messages go away.
What would be an appropriate way to do this - for a specific file or part of code only?
Surpressing errors with @'s seems like a bad idea since it apparently slows the code down...
Thanks!
Hi, consider the following code:
const QString& MyClass::getID(int index) const
{
if (i < myArraySize && myArray[i]) {
return myArray[i]->id; // id is a QString
} else {
return my_global_empty_qstring; // is a global empty QString
}
}
How can I avoid to have an empty QString without changing the return type of the method? (It seems that returning an empty QString allocated on the stack is a bad idea)
Thanks.
I am trying to make 3 rows of 4 buttons each that will take up the entire width of the screen. I have tried Linear Layout but have trouble adding a second row and from what I have read nesting Linear Layouts is bad practice. I tried to use relative layout several times but I cannot manage to get the buttons to fill the width of the screen because it ignores layout_weight, I then tried nesting linear layout in relative layout but layout_weight is still ignored.
What is the best way to accomplish this?
Hey,
im using a connection to a server in my php script, opened with fsockopen() and i want it to share between different pages so i serialized it and saved it in a session variable but it seems that that ia a bad idea because when i do this nothing happens...
Not even an error.
The problem is that this connection requires a handshake so i cant reconnect everytime
Another question, whats the timeout of fsockopen or does the connection stay alive if the. original php script which called it is closed?
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 ?
First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed.
My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms.
It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)
I'm executing the following query
SELECT COUNT(*)
FROM table
WHERE field1='value' AND (field2 = 1000 OR field3 = 2000)
There is one index over field1 and another composited over field2&field3.
I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146.000 rows.
Suggestions on how to improve this? 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 ?
The idea behind the question is -
Just say No! to C# Regions
It is said that "the reason to use #region tags because all the things they are hiding is just really bad code."
How do you use regions effectively?
Example:
@try {
// 1) do bad stuff that can throw an exception...
// 2) do some more stuff
// 3) ...and more...
}
@catch (NSException *e) {
NSLog(@"Error: %@: %@", [e name], [e reason]);
}
If 1) throws an exception, is the block immediately canceled like a return in a function or a break in a loop? Or will 2) and 3) be processed no matter what happens in 1)?
I have a 200kb file, what I use in multiple pages, but on each page I need only 1-2 lines of that file so how I can read only these lines what I need if I know the line number?
For example if I need only the 10th line, I don`t want to load in memory all the lines, just the 10th line.
Sorry for my bad english!
I was wondering if anyone new how to get access the metadata (the date in particular) from jpg, arw and dng files.
I've recently lost the folder structure after a merge operation gone-bad and would like to rename the recovered files according to the metadata.
I'm planning on creating a little C++ app to dig into each file and get the metadata.
any input is appreciated.
( alternatively, if you know of an app that already does this I'd like to know :)
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 bind custom DataTable to DataGrid through ObjectDataSource, where i use SelectMethod and UpdateMethod. SelectMethod working great, but when I try to update row it's breaking by MissingMethodException. What should i do to fix this problem?
Sorry for my bad english ;)
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 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.
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 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 have the code:
private void Button1_Click (object sender, EventArgs e)
(
Form2 f2 = new Form2 ();
f2.Show ();
)
how to make so that Form2 when you click on Button1 not opened for the second time, if it is open?
sorry for bad english
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!
