public class RecordService
{
`private readonly ISystemTime systemTime;`
public RecordService(ISystemTime systemTime)
{
this.systemTime = systemTime;
}
public void RouteRecord(Record record)
{
if (record.Created <
systemTime.CurrentTime().AddMonths(-2))
{
// process old record
}
// process the record
}
}
In the unit test you can use mock object and decide what to return
[TestClass]
`public class When_old_record_is_processed`
`{`
`[TestMethod]`
`public void Then_it_is_moved_into_old_records_folder()`
`{`
`var systemTime = A.Fake<ISystemTime>(); `
`A.CallTo( () => system.Time.CurrentTime())`
`.Returns(DateTime.Now.AddYears(-1));`
var record = new Record(DateTime.Now);
var service = new RecordService(systemTime);
service.RouteRecord(record);
// Asserts...
}
`}`
I don’t like to inject another interface into my class just to get the current time. It feels too heavy solution for a such a small problem. The solution is to use static class with public function.
public static class SystemTime
{
`public static Func<DateTime> Now = () => DateTime.Now;`
`}`
Now we can remove the ISystemTime injection and RecordService looks like this
public class RecordService
`{`
`public void RouteRecord(Record record)`
`{`
`if (record.Created < SystemTime.Now.AddMonths(-2))`
`{`
`// process old record`
`}`
// process the record
}
}
In the unit tests we can mock the system time just as easily.
[TestClass]
`public class When_old_record_is_processed`
`{`
` [TestMethod]`
`public void Then_it_is_moved_into_old_records_folder()`
`{`
`SystemTime.Now = () => DateTime.Now.AddYears(-1); `
`var record = new Record(DateTime.Now);`
`var service = new RecordService();`
service.RouteRecord(record);
// Asserts...
}
}
Of course there is a downside to all this. You are using public fields (The HORROR!) so nobody is stopping you writing code like this.
public class RecordService
`{`

Also I think it is better to educate developers than create abstractions just to protect them from doing any mistakes. Other possible issues are related to running the tests.

You can use the same logic to mock file system operations
public static class FileSystem
`{`
` public static Action<string, string> MoveFile = File.Move;`
`}`
In my opinion implementing this kind of functionality (mocking time, simple file system operations) using public functions is perfectly acceptable. It makes the code easier to read, decreases the dependencies and it is easy to mock in the unit tests. | c# | unit-testing | mocking | null | null | 04/02/2012 01:40:53 | not a real question | How to mock DateTime.Now in unit tests?
===
The normal solution is to hide it behind interface.
public class RecordService
{
`private readonly ISystemTime systemTime;`
public RecordService(ISystemTime systemTime)
{
this.systemTime = systemTime;
}
public void RouteRecord(Record record)
{
if (record.Created <
systemTime.CurrentTime().AddMonths(-2))
{
// process old record
}
// process the record
}
}
In the unit test you can use mock object and decide what to return
[TestClass]
`public class When_old_record_is_processed`
`{`
`[TestMethod]`
`public void Then_it_is_moved_into_old_records_folder()`
`{`
`var systemTime = A.Fake<ISystemTime>(); `
`A.CallTo( () => system.Time.CurrentTime())`
`.Returns(DateTime.Now.AddYears(-1));`
var record = new Record(DateTime.Now);
var service = new RecordService(systemTime);
service.RouteRecord(record);
// Asserts...
}
`}`
I don’t like to inject another interface into my class just to get the current time. It feels too heavy solution for a such a small problem. The solution is to use static class with public function.
public static class SystemTime
{
`public static Func<DateTime> Now = () => DateTime.Now;`
`}`
Now we can remove the ISystemTime injection and RecordService looks like this
public class RecordService
`{`
`public void RouteRecord(Record record)`
`{`
`if (record.Created < SystemTime.Now.AddMonths(-2))`
`{`
`// process old record`
`}`
// process the record
}
}
In the unit tests we can mock the system time just as easily.
[TestClass]
`public class When_old_record_is_processed`
`{`
` [TestMethod]`
`public void Then_it_is_moved_into_old_records_folder()`
`{`
`SystemTime.Now = () => DateTime.Now.AddYears(-1); `
`var record = new Record(DateTime.Now);`
`var service = new RecordService();`
service.RouteRecord(record);
// Asserts...
}
}
Of course there is a downside to all this. You are using public fields (The HORROR!) so nobody is stopping you writing code like this.
public class RecordService
`{`
`public void RouteRecord(Record record)`
`{`
`SystemTime.Now = () => DateTime.Now.AddYears(10);`
`}`
`}`

I'm in the progress of writing a web server script that lets you create custom iOS apps (basically exchanging logos and a few other things). The web server customizes a previously uploaded "shell" .ipa and re-zips the whole container to send it to the user's browser. That is: we customize a previously uploaded .ipa on the web server and let the user download it for submission to the App Store.
The next step would be to re-codesign the whole .ipa - because we changed the .IPA contents and the user must use his own signing identity - so that he can actually upload it to the App Store.
From what I understand, there is a "CodeResources" file which contains some kind of hash for each resource file in the bundle, and the executable contains some kind of embedded signature as well. To generate these, you'd have to use the "codesign" utility on the user's computer, then use Application Loader to submit it to the App Store. Correct so far?
What I'm trying to find out is:
1. Is there a way to codesign the .ipa on the server (with having the user upload his certificate beforehand), so that he does not have any extra work to do?
2. If 1) is not possible, is there some kind of tool that allows to re-codesign the .ipa without much hassle? Xcode seems to require some project setup work to do just a bit of code signing - if possible at all.
3. Are there any alternative ways to codesign the .ipa files for the user - possibly without having to manually do it by hand?
Thanks in advance!

- Radio
- Visible Light
- Sound
- Wi-Fi
- 3G
And I believe that the best solution would be sound, low hertz like below the spectrum which animals / humans can hear.
Why do I believe that sound would be easiest?
<br>Because it can bounce on walls and mostly anything to get to a reciever and because it's the easiest way and most likely cheapest way to do it.
The question is: where do I find / how do I make such a device that can send and read low hertz? I don't know what range I'm talking about, but atleast something that won't disturb animals or humans hehe.

(That is, a C# program uses PInvoke to call my custom shared library which in turn calls another shared library.)
In Windows, my custom shared library links to the shared library when my custom library links and when the C# application executes, all symbols are resolved.
On Linux, linking my shared library does not link the other shared library. With a C++ driver, I specify the other library when the *application* is linked and at that time, all symbols are resolved. However, when I try to call my shared library from a C# program (compiled using mono) symbols in the other shared library are not resolved. I've tried using the MONO_PATH variable to specify the other library but it seems not to make a difference. I've also tried specifying the unresolved function in a DLLimport statement, but that seems not to help either.
How can I specify a shared library that is not directly called by C# code so that mono/cli finds it at run time?
I use the following commands to build the shared library:
g++ -fPIC -g -c -Wall libexif-wrapper.cpp
g++ -shared -Wl,-soname,libexif-wrapper.so.1 -o libexif-wrapper.so.1.0.1 libexif-wrapper.o -lc
ar rcs libexif-wrapper.a libexif-wrapper.so.1
And the following command line to compile my C# driver:
mcs -unsafe -define:LINUX Test-libexif-wrapper.cs
On execution I get an error that a symbol used by my shared library is not found:
/usr/bin/cli: symbol lookup error: ../../../C/libexif-wrapper/libexif-wrapper/libexif-wrapper.so.1: undefined symbol: exif_data_new_from_file
(libexif-wrapper is my shared library which serves as a shim between the C# application and libexif.)
I have not been able to figure out how to solve this. Any suggestions would be appreciated.

I have an x-code project of my iPhone app which I want to charge money for it. In addition to that app, I would like to deploy additional "light" version of this app free of charge which of course will have some limitations.
Best way I can think of is adding a new 'Light' configuration in my existing x-code project and define a constant like LIGHT_VERSION only in this configuration that will be tested in my code.
Will that solution work? or do I have to create a new 'Light' project pointing to all sources and resources of original project?

Like I have the main Namespace for my data access layer so let's say I have this namespace as my data layer ..DAL

Can someone explain why this is happening? Is there something I could do to the `UserSetting` class to make the problem disappear? The application is quite performance sensitive and I'd rather not have the exception.

Can anyone with Windows programming expertise clarify whether this is happening because Mozilla "rolled their own" objects rather than deriving from MFC, which is presumably why this action is successful on Windows own and other Microsoft applications?

Now the iframe works perfectly fine in Chrome loads the content as expected, but in Firefox it seems to have disabled javascript in this case (notice none of the script files being downloaded), which is an issue as the widgets are extremely javascript heavy and don't function without it.

PHP OO? | So, I'd say I have a firm grip on procedural PHP and would like to start looking at the OO style of programming. I've googled and found *enough* tutorials about objects/classes etc demonstrated with chimps, cars, fingers, whatever which just isn't useful. I'd like real-world examples and whilst I've seen other questions here answered with links to real examples, I feel they're still a little too fast-paced.
I'm not saying that I'm incapable of learning OO or that I feel it's too advanced, its just I appreciate the fact that OO is a colossal topic and would rather learn properly from the start, knowing the right standards and practises, learning everything in depth rather than being introduced to advanced features in a few sentences.
If anybody cares to link me to some good online tutorials of this calibre, that would be wonderful - I really wouldn't mind a few book recommendations either (Amazon UK please :)) since usually published author's work is trustworthy.
Also - is it worth me looking at another language to get to grips with the OO mindset? I've read that other languages (say, Java?) that force you to have object orientation are a much better way of learning the ropes?
All input appreciated and I'll be sure to mark the correct answer when I get it. :)

This is a very simple shopping cart exercise I'm doing to learn ASP. I create the session, add things to it, and then on the checkout page should be able to remove items from the cart one by one. If I click remove, the item is removed from the listbox, but not from the session. I know it persists in the session because if I click the link to the shopping page, the listbox on the shopping page will populate with the item I thought that I removed.
I've tried removing it two different ways, and I'm not sure why it isn't working.
note: The dictionary keys are the actual names of the products being used to populate the listboxes. The value entry is the productID# which I don't actually use right now. The listbox on the shopping page is being populated with data from a sqlsource. SelectedItem.Text = product name (whats shown) and SelectedValue = productID (not used).

This isn't really a question, but here's the bug report, as instructed.
Bug:
In the code file 'main.js', an object reference error occurs when a Google map is dynamically destroyed within the DOM, pointing to the marginLeft property when it no longer exists.
Solution:
Check for the object instance before trying to modify the 'marginLeft' property.

I appreciate the referral, but this is not a technical question. I don't actually have a question, but would like to report a bug against the Maps API, since this is a coding issue within the main.js code file. There isn't anything wrong with my implementation, which worked fine all through 2011, and nothing has changed. So where do bugs get reported?

Hello,
I just noticed this error today, which didn't occur in the past. I've had the same code up for a year now, and last saw this particular page about a month ago with no script errors. It's sort of strange.
Steps to reproduce:
1. Open http://whatsock.com
2. Click the Live Demo tab. (The Google map is at the bottom, with no errors)
3. Now click the Overview tab (Now the below error is generated)

print strftime("%Y-%m-%d", single_date.timetuple())
Notes:
I'm not actually using this to print; that's just for demo purposes.
The variables start_date and end_date are datetime.date objects, because I don't need the timestamps (they're going to be used to generate a report).
I checked the StackOverflow questions which were similar before posting this, but none were exactly the same.

This is working fine, but I'm looking for any feedback on how to do it better. Right now I think it's better than nested loops, but it starts to get Perl-one-linerish when you have a generator in a list comprehension. Any suggestions are welcome.

* Theres a child process started by the parent, which only has one pipe open, stdout.
* In order for the parent to end the process, it calls pclose
* We can't call read on the pipe to detect if its broken to end the process (because it's a write only pipe, read will always return immediately with an error)
Is there a way to get an event from the pipe when the read end (on the parent) closes? If not, we have to continuously write garbage to the pipe in order to detect when it closes, which is a sub-optimal and wasteful solution.

The code is:
$("#nav li ul li a #changeBG1").css("background-color","red");
And the nav HTML looks a little like this:
<ul id="nav">
<li><a href="index.php">home</a></li>
<li><a href="custHelp.php">who we are</a>
<ul>
<li id="changeBG1"><a href="about.php">about</a></li>
<li id="changeBG2"><a href="help.php">team</a></li>
</ul>
</li>
However, it does not seem to change just that one, it changes ALL of them. I can not seem to find out how to call the ID of **NAV** and then the ID of **changeBG1** so only that one will change.
The Jquery code is:
var url = window.location.href;
url = url.substr(url.lastIndexOf("/") + 1);
$("#theNav").find("a[href='" + url + "']").addClass("theNavsBG");
if (url == 'about.php'){
$("#nav li ul li a #changeBG1").css("background-color","red");
}
