Support for multilanguage applies for all kinds of messages, but tends to be forgotten in the case of error messages. |
I would second not telling the user useless esoteric information like numeric error codes. I would follow that up however by saying to definitely log that information for troubleshooting by more technically savvy people. |
Maybe you should try with ActiveReports.NET or DevExpress XtraReports to generate the reports first by code. Both have PDF export support so you can generate PDF files and send them by mail. |

For any user input (strings, filenames, values, etc), always display the erroneous value with delimiters around it (quotes, brackets, etc). e.g.
The filename you entered could not be found: "somefile.txt"

Big codebases will need it. Look at boost for an example. I don't think anyone would call the boost code 'insane'.

Obviously it's a matter of opinion. But it really boils down to organization. For example, I have a project which has a plugin api that has functions/objects which look something like this:

Ruby and WS-Security |

I'm having troubles finding good Ruby libraries that implement WS-Security. I've seen [wss4r][1] but have yet to use it (and the documentation is a bit light on it). What libraries do you use for this task, or is there a better alternative?

Add the objects you want to remove to a second array and, after the loop, use -removeObjectsInArray:. |
FolderShare is also nice for syncing files. I use it to keep documents, etc. in sync between my laptop and my desktop, for example.
Of course, for code especially this doesn't obviate the need for source control. |

As mentioned above by Greg, programmatically you can use the function_exists() method. Don't forget you can also use the following to see all the environment specifics with your PHP install using the following:
<?php
phpinfo();
?>
|
Why don't you add the objects to be removed to another NSMutableArray. When you are finished iterating, you can remove the objects that you have collected. |
Either use loop counting down over indices – for (NSInteger i = array.count - 1; i >= 0; --i) – or make a copy with the objects you want to keep. In particular, do not use a for(id object in array) loop or NSEnumerator. |
this should do it:
NSMutableArray* myArray = ....;
int i;
for(i=0; i<[myArray count]; i++) {
id element = [myArray objectAtIndex:i];
if(element == ...) {
[myArray removeObjectAtIndex:i];
i--;
}
}
hope this helps... |
source control with VB2005 Express |
|vb.net|version-control| |
Can anyone suggest a good source control system that interfaces with VB2005 Express? As the Express editions of Visual Studio do not allow add-ins does this mean that I will not be able to integrate source control into the IDE? I'm used to the check-in/check-out process of SourceSafe integrated into VB6. Can anyone rec... |
Another idea might be to have the handsets divided into 2 to 4 categories based on say screen dimensions and create builds for them. It is a much faster route too as you will be able to support all the handsets you want to support with much lesser complexity.
Another thing to see is the BREW versions on the handsets... |
Casting a function which returns (void *) to instead be an (int *) is harmless: you're casting one type of pointer to another.
Casting a function which returns an integer to instead be a pointer is most likely incorrect. The compiler would have flagged it had you not explicitly cast it. |

Although it cannot handle the UI side, I unit test MFC code using the Boost Test library. There is a Code Project article on getting started:
[Designing Robust Objects with Boost][1]

There's no magic number, but there's a few things that affect performance in particular:
- Index Cardinality: don't bother indexing a row that has 2 or 3 values (like an ENUM). On a large table, the query optimizer will ignore these.
- There's a trade off between writes and indexes. The more indexes you have, t... |
One possible error could (depending on this is whether what you really want or not) be mallocing with one size scale, and assigning to a pointer of a different type. E.g.,
int *temp = (int *)malloc(sizeof(double));
There may be cases where you want to do this, but I suspect that they are rare.
|
Well, I think it's the exact opposite - always directly cast it to the needed type.

The problem with Google Docs is that it changes the format of uploaded docs in its own format, with catastrophic consequences (page layout, links, summaries...). What I would like is to keep my original documents as is , if I want to . |
Complementing @vonc's answer, don't accept ambiguous abbreviations. Eg:

I see a lot of Windows command line specifics, but if your program is intended for Linux, I find the [GNU command line standard][1] to be the most intuitive. Basically, it uses double hyphens for the long form of a command (e.g., `--help`) and a single hyphen for the short version (e.g., `-h`). You can also "stack" the... |

Sounds like you are participating in a bit of premature optimization. If the application is not built, while performance concerns are good to be aware of, your primary concern should be getting the app written.

For collections they need to have an Add method taking a single argument. If you just need a text format and not specifically xml you might try JSON. I've developed one for .NET, [JsonExSerializer][1], and there are others available as well at [http://www.json.org][2].

It's equivalent to Nullable< DateTime>. You can append "?" to any primitive type or struct. |
[Unitils][1] does this w/ the static method `assertRefEquals`.

Since <code>DateTime</code> is a <code>struct</code>, not a <code>class</code>, you get a <code>DateTime</code> *object*, not a *reference*, when you declare a field or variable of that type. And, in the same way as an <code>int</code> cannot be <code>null</code>, so can this <code>DateTime</code> object never be null,... |
It takes the last two digits of the year and pads the left side with zeroes to a maximum of 2 characters. Looks like a "just in case" for expiration years ending in 08, 07, etc., making sure that the leading zero is present. |
There are a couple of different strategies to writing quines. The obvious one is to just write code that opens the code and prints it out. But the more interesting ones involve language features that allow for self-embedding, like the %s-style printf feature in many languages. You have to figure out how to embed someth... |
You should be able to add `@login_required` decorators across the board and be done with it. Unless you have a boat-load of view functions, it shouldn't be too horrible. |
OK so it's taking the value from the drop down, ABCD
Then it takes the substring from position 2, CD
And then it err, left pads it with 2 zeros if it needs too, CD
Or, if you've just ended X, then it would substring to X and pad to OX
|
It's taking the last two digits of the year, then pad to the left with a "0".
So 2010 would be 10, 2009 would be 09.
Not sure why the developer didn't just set the value on the dropdown to the last two digits, or why you would need to left pad it (unless you were dealing with years 0-9 AD). |
