class NewCombo : System.Windows.Forms.ComboBox
{
public NewCombo() { DropDownItems = 50; }
}
The problem is that the base class property "DropDownItems" has a 'default' attribute set on it that is a different value (not 50). As a result, when I drag the control onto a form, the designer file gets an explicit 'mycontrol.DropDownItems = 50;' line.
At first this doesn't matter. But if later I change my inherited class to 'DropDownItems = 45;' in the constructor this does not affect any of the controls on any form since all those designer files still have the value 50 hardcoded in them. And the whole point was to have the value set in one place so I can deal with the customer changing his mind.
Obviously, if I were creating my own custom property in the subclass, I could give it its own designer default attribute of whatever I wanted. But here I'm wanting to change the default values of properties in the base. Is there any way to apply Visual Studio attributes to a base class member?

I have a project (I'll call it myproject) that includes another project (vendor). The vendor project is a standalone project maintained by someone else. Including a project like this is fairly [straightforward][1], but in this case there is a tiny snag: each project generates its own config.h file, each of which defines standard macros such as PACKAGE, VERSION, etc. This means that, during the build, when vendor is being built, I get lots of errors like this:
... warning: "VERSION" redefined
... warning: this is the location of the previous definition
... warning: "PACKAGE" redefined
... warning: this is the location of the previous definition
These are just warnings, for the time being at least, but I would like to get rid of them. The only relevant information I've been able to turn up with a google search is [this][2] thread on the automake mailing list, which isn't a whole lot of help. Does anybody else have any better ideas?

It's usually done at the last minute (or not at all), next to no time gets allocated to it, etc.
In the past I've picked a tool, installed it on my machine first, hit the home page, upping the concurrency settings. Then I'd write a simple login script, a simple site walkthrough (in an ecommerce site adding a few items to a cart and checkout). Then I'd rope in as many developers as I could, install the stress test tool on their machines and do a massive attack. If nothing broke I'd give up and wait for the actual traffic to kill the site for real.
Just hitting the homepage hard almost always would locate a major problem. More scalability problems would surface at the second stage, and even more - after the launch.
The tools I used were Microsoft Homer (aka <a href="http://www.microsoft.com/downloads/details.aspx?familyid=e2c0585a-062a-439e-a67d-75a89aa36495&displaylang=en">Microsoft Web Application Stress Tool</a>) and <a href="http://www.pylot.org/">Pylot</a>.
The reports that these tools generated never made much sense to me, and I spent many hours trying to figure out what kind of concurrent load the site would be able to support.

Where do you put classes for stuff which is both infrastructural and domain specific (for instance I have a FileStorageStrategy class, which stores the files either in the database, or alternatively in database)?

For instance; I have a I/O Completion Port class that throws in the constructor if it can't initialise the port correctly. This uses the Win32 function of CreateIoCompletionPort in the initialiser list. If the handle isn't set correctly - a non-null value - then the constructor will throw an exception. I have never seen this function fail.
I am pretty certain that this (and other functions like it in my code) if they fail will behave correctly, the code is 50 lines long including white-space, so my questions are a) is it worth testing that it will throw, b) and if it is worth testing, how to?
For b) I thought about overriding CreateIoCompletionPort and passing the values through. In the unit test override it and cause it to return 0 when a certain value is passed in. However since this is used in the constructor then this needs to be static. Does this seem valid or not?

That's because the select element is considered an ActiveX object and is on top of every HTML element in the page.
I already saw people hiding selects when opening a popup div, that leads to pretty bad user experience having controls disappearing.
FogBugz actually had a pretty smart solution (before v6) of turning every select into text boxes when a popup was displayed. This solved the bug and tricked the user eye but the behavior was not perfect.
Another solution is in FogBugz 6 where they no more use the select element and recoded it everywhere.
Last solution I currently use is messing up the IE rendering engine and force it to render the absolutely positioned div as an ActiveX element too, ensuring it can live over a select element. This is achieved by placing an invisible iframe inside the div and styling it with:
#MyDiv iframe
{
position: absolute;

- Still have to use PrintDocument to print the memory stream, which is unsupported in a Windows Service (though it may work - haven't gotten that far with the prototype yet)

For instance in .Net 2.0
public interface IHaveChildren {
string ParentType { get; }
int ParentId { get; }
List<IChild> GetChildren()
}
Can (in 3.5) become:
public interface IHaveChildren {
string ParentType { get; }
int ParentId { get; }
}
public static HaveChildrenExtension {
public static List<IChild> GetChildren( this IHaveChildren ) {
//logic to get children by parent type and id
//shared for all classes implementing IHaveChildren
}
}
This seems to me to be a better mechanism for many interfaces. They no longer need an abstract base to share this code, and functionally the code works the same. This could make code more maintainable and easier to test.
The only disadvantage being that an abstract bases implementation can be virtual, but can that be worked around (would an instance method hide an extension method with the same name? would it be confusing code to do so?)
Any other reasons not to regularly use this pattern? | c# | .net-3.5 | extension-methods | null | null | null | open | Extension interface patterns

Should you have properties that you populate, or use paramterized sub's to load the information in your controls?
Part of my fear of using paramteter's is the fact that I cannot make sure that everything will be populated.

I've read about the [Binary Log][1], is that the way that I need to go? Will that not slow down the fallback server a lot? Is there a way to not include some tables in the binary log - where it doesn't matter that the data has changed?

here's i found about the different, but still not make me statisfied
i found this:
> The Session class permits you maintain a user's "state" and track their activity while they browse your site. The Session class stores session information for each user as serialized (and optionally encrypted) data in a cookie. It can also store the session data in a database table for added security, as this permits the session ID in the user's cookie to be matched against the stored session ID. By default only the cookie is saved.

I've tried reading through several tutorials (none of which were that great). I've tried using both Zend and XDebug.
I'm not even sure on exactly how I'm supposed to be using this thing once it's set up properly.
I tried setting a break point in my PHP code, right-clicking the PHP file in the text editor, and selecting 'debug php web application', but it never hits the break point. It opens up a browser within eclipse with some GET parameters attached to my normal URL:
> ?debug_host=192.168.1.2%2C127.0.0.1&start_debug=1&debug_port=10000&original_url=http%3A%2F%2Flocalhost%2Fparticipants&send_sess_end=1&debug_stop=1&debug_start_session=1&debug_no_cache=1331422177353&debug_session_id=1000
One thing I wasn't sure about in my project php debugging properties was the PHP executable field. It was automatically set to 'none', so I had to create an entry that pointed to '/usr/bin/php'. Maybe this isn't correct?
I went as far as creating a simple application with one php file that just had a few echo statements. I can't get the debugger to hit a breakpoint in that either.

The other thing is that it only shows one row of content (sentence finish with 3 dots and it doesn't show the rest of the text), but I guess it has to do with this.

When I try to run this code the compiler doesn't give me any errors, it just hangs and never finishes compiling. I know that it's this line because if I declare this with a shorter string, or with other types of declaration (like putting commas between each char), it works.
Is there a line length limit in the arduino code that's stopping me?
If I have to just accept this and put commas between every char is there a good method?

I believe this is due to the way I've setup the Visual Studio solutions. Hopefully the more projects we run in this environment the better our understanding of how to set them up will be so I'm not questioning why the conflicts happen at this stage.
