<pre>
#define foreach(var, container) for (typeof((container).begin()) var = (container).begin(); var != (container).end(); ++var)
</pre>
It is used like this:
<pre>
std::vector< Blorgus > blorgi = ...;
foreach(blorgus, blorgi) {
blorgus->draw();
}
</pre>
I would like to make something similar that iterates over a map's values. Call it "foreach_value", perhaps. So instead of writing
<pre>
foreach(pair, mymap) {
pair->second->foo();
}
</pre>
I would write
<pre>
foreach_value(v, mymap) {
v.foo();
}
</pre>
I can't come up with a macro that will do this, because it requires declaring two variables: the iterator and the value variable ('v', above). I don't know how to do that in the initializer of a for loop, even using gcc extensions. I could declare it just before the foreach_value call, but then it will conflict with other instances of the foreach_value macro in the same scope. If I could suffix the current line number to the iterator variable name, it would work, but I don't know how to do that.

class ToBeTested {
public:
void doForEach() {
for (vector<Contained>::iterator it = m_contained.begin(); it != m_contained.end(); it++) {
doOnce(*it);
doTwice(*it);
doTwice(*it);

}
void doOnce(Contained & c) {
// do something
}
void doTwice(Contained & c) {
// do something
}
// other methods
private:
vector<Contained> m_contained;
}
I want to test that if I fill vector with 3 values my functions will be called in proper order and quantity. For example my test can look something like this:
tobeTested.AddContained(one);
tobeTested.AddContained(two);
tobeTested.AddContained(three);
BEGIN_PROC_TEST()
SHOULD_BE_CALLED(doOnce, 1)

SHOULD_BE_CALLED(doOnce, 1)
SHOULD_BE_CALLED(doTwice, 2)
SHOULD_BE_CALLED(doTwice, 2)
tobeTested.doForEach()
END_PROC_TEST()
How do you recommend to test this? Are there any means to do this with CppUnit or GoogleTest frameworks? Maybe some other unit test framework allow to perform such tests?
I understand that probably this is impossible without calling any debug functions from these functions, but at least can it be done automatically in some test framework. I don't like to scan trace logs and check their correctness.

Now while the application works well, the other day I was having a look at the routine that I use to generate the SQL string to pass the database and frankly, it was bad.
I was just posting a question here to see if anyone else has a better way of doing this.
What I have is a form with a bunch of controls ranging from text boxes to radio buttons, each of these controls are like database filters and when the user hits search button, a SQL string(I would really like it to be a LINQ query because I have changed to LINQ to SQL) gets generated from the completed controls and run.
The problem that I am having is matching each one of these controls to a field in the database and generating a LINQ query efficiently without doing a bunch of "if ...then...else." statements. In the past I have just used the tag property on the control to link to control to a field name in the database(don't flame I was still only a noob at that time)
I'm sorry if this is a bit confusing, its a bit hard to describe. Just throwing it out there to see if anyone has any ideas.
Thanks

My current project requires me to do different things based on different HTTP request headers for nearly every action.
Currently, I have one massive Controller, and every action method has an ActionName attribute (so that I can have multiple versions of the same action that takes the same parameters, but does different things) and a custom FilterAttribute that checks if certain headers have certain values.
I would really like to push the code into separate Controllers, and have the RouteTable select between them based on the headers, but can't think of the cleanest way to do this.
## Example ##
For example, say I have a list of files. The service must process the request in one of two ways:
1. The client wants a zip file, and passes "accept: application/zip" as a header, I take the list of files, pack them into a zip file, and send it back to the client.
2. The client wants an html page, so it passes "accept: text/html", the site sends back a table-formatted html page listing the files. | asp.net-mvc | routing | asp.net | .net | null | null | open | Best way to differentiate MVC Controllers based on HTTP headers

The user is able to change this value, then click on a button where the code behind basically iterates through each DataGridItem in the grid, does a FindControl for the ID of the textbox then assigns the .Text value to a variable which is then used to update the database. The datagrid is rebound with the new values.
The issue I'm having is that when assigning the .Text value to the variable, the value being retrieved is the original databound value and not the newly entered user value. Any ideas as to what may be causing this behaviour?
Code sample:
foreach(DataGridItem dgi in exGrid.Items)
{
TextBox Text1 = (TextBox)dgi.FindControl("TextID");

Currently I have this working mapping the collection as type Int32 and NH seems to take care of it, but it's not exactly ideal.

I found a post that said to define a class as
public class CEnumType : EnumStringType {
public CEnumType() : base(MyEnum) { }
}
and then map the enum as CEnumType, but this gives "CEnumType is not mapped" or something similar.
So has anyone got experience doing this?

{
public enum EAction
{
do_action,
do_other_action

I have to choose between designing my web-based forms and writing code for them in Visual Studio Tools for Applications (aka VSTA) or Visual Studio Tools for Office (aka VSTO). VSTA is included free as part of the license for InfoPath 2007; VSTO, also free, requires Visual Studio 2005 / 2008. I have licenses for both of the products and cannot easily decide what the pros and cons of each IDE might be. | 0 |

The most common scenario I have seen is to use a single sql account with the permissions set to what is required by the application. This account is used by all application calls. Then when people require access over the database via query tools or such a seperate Group is created with the query access and people are given access to that group.
The other scenario I have seen is to use complete Windows Authentication End to End. So the users themselves are added to groups which have all the permissions set so the user is able to update and change outside the parameters of the application. This normally involves securing people down to the appropiate stored procedures so they aren't updating the tables directly.
The first scenario seems relatively easily to maintain but raises concerns if there is a security hole in the application then the whole database is compromised.
The second scenario seems more secure but has the opposite concern of having to much business logic in stored procedures on the database. This seems to limit the use of the some really cool technologies like Nhibernate and LINQ. However in this day and age where people can use data in so many different ways we don't forsee e.g. mashups etc is this the best approach. | asp.net | sql | nhibernate | null | null | null | open | Database Authentication for Intranet Applications

With the passing of Moore's law do you thing that there might be a shift away from Frameworks?
I suspect that one of the reasons for Vista not being an outstanding success was that it ran much slower than XP, and, because computers had not improved as greatly in speed as in the past, this change seemed like a step backwards.
For years CPU speed outstripped the speed of software so new frameworks that adding layers of OS obfuscation and bloat did little harm. Just imagine how fast Windows 95 would run on todays hardware (given a few memory tweaks). Win2K then WinXP were great improvements, and we could live with them being slower because of faster computers.
However, even years ago, I noticed that programs written say in MS foundation classes didn't seem quite as crisp as code doing the same thing written directly to the API. Since the proliferation of these frameworks like .Net and others can only have made this situation worse, is it possible that we might discover that being above to write code in 'C' directly to the Win32 API (or the equivalent in other OS's) will become a strong competitive advantage, even if it does take longer to write?

Fair enough, but is there a workaround to allow a Generic Enum, or am I going to have to mimic the Parse function and pass a type as an attribute, which forces the ugly boxing requirement to your code. | c# | generics | enums | null | null | null | open | Create Generic method constraining T to an Enum
===
I'm building a function to extend the Enum.Parse concept that
- allows a default value to be parsed in case that an Enum value is not found
- Is case insensitive
So I wrote the following
public static T GetEnumFromString<T>(string value, T defaultValue) where T : Enum
{
if (string.IsNullOrEmpty(value)) return defaultValue;
foreach (T item in Enum.GetValues(typeof(T)))
{
if (item.ToString().ToLower().Equals(value.Trim().ToLower())) return item;
}
return defaultValue;
}

The first interesting thing that I realized is that Visual Studio does not automatically generate the ProfileCommon proxy class for you. That's not a big deal since it's simpy a matter of extending the ProfileBase class. After creating a ProfileCommon class, I wrote the following Action method for creating the user profile.
<pre><code>[AcceptVerbs("POST")]
public ActionResult CreateProfile(string company, string phone, string fax, string city, string state, string zip)
{
MembershipUser user = Membership.GetUser();
ProfileCommon profile = (ProfileCommon)ProfileCommon.Create(user.UserName, user.IsApproved) as ProfileCommon;
profile.Company = company;
profile.Phone = phone;
profile.Fax = fax;
profile.City = city;
profile.State = state;
profile.Zip = zip;
profile.Save();
return RedirectToAction("Index", "Account");
}</code></pre>
The problem that I'm having is that the call to ProfileCommon.Create() cannot cast to type ProfileCommon, so I'm not able to get back my profile object, which obviously causes the next line to fail since profile is null.
Following is a snippet of my web.config:
<pre><code><profile defaultProvider="AspNetSqlProfileProvider" automaticSaveEnabled="false" enabled="true">
<providers>
<clear/>
<add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/" />

<add name="City" type="string" />
<add name="State" type="string" />
<add name="Zip" type="string" />
<add name="Email" type="string" >
</properties>
</profile></pre></code>
The MembershipProvider is working without a hitch, so I know that the connection string is good.
Any thoughts on what I might be doing wrong?
Thank you in advance...

Is there a way to strip down the WPF or Forms? and if im stuck using CLR or MFC what would be the easiest way to make it pretty. (my experience with MFC is making very award forms) | 0 |

Unrotated, the major axis of the ellipse spans the width of my viewport. When I rotate 90-degrees about my line-of-sight, the major axis of the ellipse now spans the height of my viewport, thus deforming the ellipse (in this case, making it appear less eccentric).

What do I need to do to prevent this deformation (or at least account for it), so rotation about the line-of-sight preserves the perceived major axis of the ellipse (in this case, causing it to go beyond the viewport)?

I find it very reassuring to have tests that verify the functionality of my code, but it's been tricky to follow some of the recommened practices of TDD. Namely, writing tests first has been hard. And I'm finding it difficult to make my tests readable (due to extensive use of a mocking library).
I chose a mocking library called [mocker](http://labix.org/mocker). I use it a lot since much of the code I'm testing makes calls to (a) other methods in my application that depend on system state or (b) ObjC/Cocoa objects that cannot exist without an event loop, etc.
Anyway, I've got a lot of tests that look like this:
def test_current_window_controller():
def test(config):
ac = AppController()
m = Mocker()
ac.iter_window_controllers = iwc = m.replace(ac.iter_window_controllers)
expect(iwc()).result(iter(config))
with m:
result = ac.current_window_controller()
assert result == (config[0] if config else None)
yield test, []
yield test, [0]
yield test, [1, 0]
Notice that the code this is actually three tests; all use the same parameterized test function. Here's the code that is being tested:
def current_window_controller(self):
try:
# iter_window_controllers() iterates in z-order starting
# with the controller of the top-most window
# assumption: the top-most window is the "current" one
wc = self.iter_window_controllers().next()
except StopIteration:
return None
return wc
One of the things I've noticed with using mocker is that it's easier to write the application code first and then go back and write the tests second, since most of the time I'm mocking many method calls and the syntax to write the mocked calls is much more verbose (thus harder to write) than the application code. It's easier to write the app code and then model the test code off of that.
I find that with this testing method (and a bit of discipline) I can easily write code with 100% test coverage.
I'm wondering if these tests are good tests? Will I regret doing it this way down the road when I finally discover the secret to writing good tests?
Am I violating the core principles of TDD so much that my testing is in vain?

Using jQuery, how would you select the img tags with class "a" that are adjacent to #active (the middle four, in this example)?
You could do it fairly easily by looping over all the following and preceding elements, stopping when the filter condition fails, but I was wondering if jQuery could it natively?

Also, I am doing all of my development locally, using MAMP, so if somebody could tell me how to set up my local environment to work in the same manner (I've read this is more difficult), I would greatly appreciate it. Honestly, I have been trying a everything to no avail, and since this is my first time doing something like this, I am completely lost. Thanks so much for any help! | subdomain | mamp | localhost | wildcard | wildcard-subdomain | null | open | Wildcard Subdomains
