return $value ? $value : $default;

but when i pass in a variable that doesn't exist such as an non existent array key i'll get a warning:

*Notice: Undefined index: cool in file.php on line 7*
I know i can suppress the error by doing this:
defaultValue(@$bob['cool'], 'beans');
but is there anything I can do in to the function that won't throw an error if it get's passed an invalid argument. Much like the function empty(). I know i'm only try to save a character's worth of work, but I'm trying to learn as well.

class Parser
{
...
double matrix_[4][4];
};
The user of this class needs to call an API function (as in, a function I have no control over, so I can't just change its interface to make things work more easily) that looks like this:
void api_func(const double matrix[4][4]);
The only way I have come up with for the caller to pass the array result to the function is by making the member public:
void myfunc()
{
Parser parser;
...
api_func(parser.matrix_);
}
Is this the only way to do things? I'm astounded by how inflexible multidimensional arrays declared like this are. I thought <code>matrix_</code> would essentially be the same as a <code>double**</code> and I could cast (safely) between the two. As it turns out, I can't even find an _unsafe_ way to cast between the things. Say I add an accessor to the <code>Parser</code> class:
void* Parser::getMatrix()
{
return (void*)matrix_;
}
This will compile, but I can't use it, because there doesn't seem to be a way to cast back to the weirdo array type:
// A smorgasbord of syntax errors...
api_func((double[][])parser.getMatrix());
api_func((double[4][4])parser.getMatrix());
api_func((double**)parser.getMatrix()); // cast works but it's to the wrong type
The error is:
> error C2440: 'type cast' : cannot convert from 'void *' to 'const double [4][4]'
...with an intriguing addendum:
> There are no conversions to array types, although there are conversions to references or pointers to arrays
I can't determine how to cast to a reference or pointer to array either, albeit that it probably won't help me here.
To be sure, at this point the matter is purely academic, as the <code>void*</code> casts are hardly cleaner than a single class member left public! | c++ | arrays | null | null | null | null | open | How to deal with arrays (declared on the stack) in C++?

Effectively, I'm taking an originator_id (a number between 0 and 99) and a 'next_element' (it's really just a sequential counter between 1 and 999,999).
We are trying to create a 6-character 'code' from them.
The originator_id is multiplied up by a million, and then the counter added in, giving us a number between 0 and 99,999,999.
Then we convert this into a 'base 32' string - a fake base 32, where we're really just using 0-9 and A-Z but with a few of the more confusing alphanums removed for clarity (I, O, S, Z).
To do this, we just divide the number up by powers of 32, at each stage using the result we get for each power as an index for a character from our array of selected character.
<pre>
Thus, an originator ID of 61 and NextCodeElement of 9 gives a code of '1T5JA9'
(61 * 1,000,000) + 9 = 61,000,009
61,000,009 div (5^32 = 33,554,432) = 1 = '1'

182,601 div (3^32 = 32,768) = 5 = '5'
18,761 div (2^32 = 1,024) = 18 = 'J'
329 div (1^32 = 32) = 10 = 'A'

I'm not desperately concerned about optimisation unless this method is actually an order of magnitude (or so) worse than any alternative.
The code only ever gets executed in small bursts, maybe generating 20 or 30 codes every 10 minutes or so. Because of the large range of numbers I don't want to pre-calculate the codes into a huge table (only small pockets of the overall code range will be used in any given installation).
However, I'm sure there's probably a tidier way of achieving the same result - particularly those divisions and subtractions.
Any constructive criticism, observations or suggestions would be most welcome.

I'm not desperately concerned about optimisation unless this method is actually an order of magnitude (or so) worse than any alternative.
The code only ever gets executed in small bursts, maybe generating 20 or 30 codes every 10 minutes or so. Because of the large range of numbers I don't want to pre-calculate the codes into a huge table (only small pockets of the overall code range will be used in any given installation).
However, I'm sure there's probably a tidier way of achieving the same result - particularly those divisions and subtractions.
Any constructive criticism, observations or suggestions would be most welcome.

Thoughts? Any help would be greatly appreciated. Thanks. | c# | installer | null | null | null | null | open | Uninstall Command Fails Only in Release Mode
===
I am able to successfully uninstall a third-party application via the command line and via a custom Inno Setup installer.
Command line Execution:
MSIEXEC.exe /x {14D74337-01C2-4F8F-B44B-67FC613E5B1F} /qn
Inno Setup Command:
[Run]
Filename: msiexec.exe; Flags: runhidden waituntilterminated;
Parameters: "/x {{14D74337-01C2-4F8F-B44B-67FC613E5B1F} /qn";
StatusMsg: "Uninstalling Service...";
I am also able to uninstall the application programmatically when executing the following C# code in debug mode.
C# Code:
string fileName = "MSIEXEC.exe";
string arguments = "/x {14D74337-01C2-4F8F-B44B-67FC613E5B1F} /qn";
ProcessStartInfo psi = new ProcessStartInfo(fileName, arguments)
{
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardOutput = true
};
Process process = Process.Start(psi);
string errorMsg = process.StandardOutput.ReadToEnd();
process.WaitForExit();
The same C# code, however, produces the following failure output when run as a compiled, deployed Windows Service:
"This action is only valid for products that are currently installed."
Additional Comments:
- The Windows Service which is issuing
the uninstall command is running on
the same machine as the code being
tested in Debug Mode. The Windows
Service is running/logged on as the
Local system account.
- I have consulted my application logs
and I have validated that the
executed command arguments are thhe
same in both debug and release mode.
- I have consulted the Event Viewer
but it doesn't offer any clues.

So I have been trying to do some simple projects at home to get better at working with .NET. I have been able to transfer much of my Java experience into working with .NET (specifically C#), but the only thing that has really perplexed me is namespaces.
I know namespaces are similar to Java packages, but as from what I can tell the main difference is that with Java packages they use actual file folders to show the seperation, while in .NET it does not and all the files reside in a single folder and the namespace is simply declared in each class.
I find this odd, because I always saw packages as a way to organize and group related code, making it easier to navigate and comprehend. Since in .NET it does not work this work this way, overtime, the project appears more overcrowded and not as easy to navigate.
Am I missing something here? I have to be. Should I be breaking things into separate projects within the solution? Or is there a better way to keep the classes and files organized within a project? | .net | organizing | null | null | null | null | open | .NET namespaces

Recently under load, I ran out of memory in my VM and it was after I added the code to serve the images so I'm pretty sure that streaming larger servlet responses is causing my troubles.
My question is : is there any best practice in how to code a java servlet to stream a large (>200k) response back to a browser when read from a database or other cloud storage?
I've considered writing the file to a local temp drive and then spawning another thread to handle the streaming so that the tomcat servlet thread can be re-used. This seems like it would be io heavy.
Any thoughts would be appreciated. Thanks. | java | java-io | null | null | null | null | open | Streaming large files in a java servlet
