This is the xml code:
<RelativeLayout android:id="@+id/descripcionRelative" android:layout_below="@+id/descripcion_bold" android:layout_width="match_parent" android:layout_height="125dip" android:background="@drawable/my_border">
<WebView android:id="@+id/webViewDescripcion" android:layout_width="wrap_content" android:layout_height="wrap_content"/>
</RelativeLayout>
The attribute android:layout_height of RelativeLayout is 125dip, because if text is too large, I want to delimitate to 125dip. If text is large, I will see text with scroll. Great!
But... if text is short, I see a lot of innecessary space.
One solution is change android:layout_height of RelativeLayout to wrap_content. If text is short, the component will have the exact pixels, but if text is too large, I can't delimitate it.
The BIG PROBLEM is that I can't calculate the WebView's height. If i do: descripcion_web.getHeight() it return 0.
If I call this method here, it doesn't return the well number:
descripcion_web.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView webView, String url) {
super.onPageFinished(webView, url);
RelativeLayout marco = (RelativeLayout)findViewById(R.id.descripcionRelative);
System.out.println("Height webView: "+webView.getHeight());
System.out.println("Height relative: "+marco.getHeight());
}
});
I try to call method in onResume() but it doesn't work.
Another attempt to solve the problem, is set android:layout_height to match_parent and use a View method setMaximumHeight(), but It doesn't exist. However, exists setMinimumHeight()...
How can I resolve this? Thank you very much! | android | webview | size | relativelayout | null | null | open | Adjusting dinamic size of layout in Android

My site is www.sweet.ie
I'm trying to get rid of the scrollbars as I want the scrolling to be done as per the JQuery (people keep trying to use the regular scrollbars and telling me theres something wrong with the site).
If I put overflow:hidden; in the Body style the site doesnt' work in IE 9 and below + Firefox. So i've taken it out and the scrollbars are there
What do I do? I'm not a crazy programmer, i'm more on the design end of things. Banging head against the wall isn't helping.
If anyone could help me I would really really appreciate it.
Thanks so much,
Aileen | 1 |

Basically what I am doing is providing a web based translation service for a "Thousands of Problems for Theorem Provers" application. I take a document written in [PSOA RuleML][1] language and translate it into [TPTP-FOF][2].
To demonstrate this translation I want to provide two RESTful web services. One to translate the PSOA RuleML and another to provide reasoning ([initial report][3]).
The first service uses Java/ANTLR3/RestEasy and the second service uses Java/ApacheCommonsExec to test the generated TPTP Strings returned from the first service against the theorem prover.
Does Apache Commons Exec provide sufficient security to do this? I realize there are other obvious solutions e.g. compose the services, to ensure that only TPTP FOF sentences are tested. But I would like to expose this theorem prover itself as a web service if possible any ideas SO. Thanks in advance!

Every time I show my family/friends what I have done they think it looks a little "basic". I am inclined to agree
I know how to customise the table view but apart from that everything I make just looks a bit "appy". All the books I have just cover the basics. There's nothing in there that looks amazing.
I know this is a very vague question but I really need to make things look better.
Do I have to be good at art?
I have heard of people using custom designs in Quartz composer, is this how they do it?

When served over http it appears to work correctly. I am using a self signed security certificate on my development machine. This is the only thing that I can think might make the difference between http and https serving the same manifest file(using relative links so the origin is correct). What is causing the difference between http and https, and how to I correct it?

The following example, adds a dictionary with a select field with a `name='tags'` attribute.
data = {}
for tag in tags:
data['tags'] = tag.name
form = Form(initial=data)
As it is expected, the loop is overwriting the key 'tags', so it only prevails the last value (and indeed, the form shows the last value). I expected that maybe passing a list would work:
data = {}
l = []
for tag in tags:
l.append(tag.name)
data['tags'] = l
form = Form(initial=data)
But in this case, it just doesn't work.
As you can imagina, I'm using a form similar to this:
class NewTopicForm(forms.Form):
... some fields
tags = ChoiceField(
widget=forms.Select(),
choices=SOME_CHOICES
)
What is the correct way to populate a form with a select field when I need to add several values?.

Based on academic research on Branding as a business function of Marketing, I have designed two questionnaires which I would appreciate you providing your input, based on your opinions and experience.
The questionnaires are anonymous and are designed to provide primary data on Brand Creation and Development conducted by start-up companies/teams/individuals in particular in the software industry.
1. Brand Development - targetted at formal small businesses, or those acting informally either individually or as part of a team to produce a product.
<http://www.kwiksurveys.com?s=OKLJKK_3ea39107>
2. Consumers - everyone can fill this questionnaire out.
<http://www.kwiksurveys.com?s=OKLJFI_65038e66>
Both questionnaires close on Thursday 29th September 2011. Please take a few moments to complete the survey; your time and support are greatly appreciated.
Kind regards,
Paul.

Yet I have profiler results showing large amounts of time spent in iostream library code (full compiler optimizations), and switching from iostreams to OS-specific I/O APIs and custom buffer management does give an order of magnitude improvement.
What extra work is the C++ standard library doing, is it required by the standard, and is it useful in practice? Or do some compilers provide implementations of iostreams that are competitive with manual buffer management?
To get matters moving, I've written a couple of short programs to exercise the iostreams internal buffering:
* putting binary data into an `ostringstream` http://ideone.com/2PPYw
* putting binary data into a `char[]` buffer http://ideone.com/Ni5ct
* putting binary data into a `vector<char>` http://ideone.com/Mj2Fi
Note that the `ostringstream` version runs fewer iterations because it is so much slower.
On ideone, the `ostringstream` is about 3 times slower than `std:copy` + `back_inserter` + `std::vector`, and about 15 times slower than `memcpy` into a raw buffer. This feels consistent with before-and-after profiling when I switched my real application to custom buffering.
These are all in-memory buffers, so the slowness of iostreams can't be blamed on slow disk I/O, too much flushing, synchronization with stdio, or any of the other things people use to excuse observed slowness of the C++ standard library iostream.
It would be nice to see benchmarks on other systems and commentary on things common implementations do (such as gcc's libc++, Visual C++, Intel C++) and how much of the overhead is mandated by the standard. | c++ | performance | iostream | null | null | 07/02/2011 02:28:23 | not constructive | Does the C++ standard mandate poor performance for iostreams, or am I just dealing with a poor implementation?

Since big software firms take the patent ownership of features, could be a feature of your software causes patent violation?
Let me explain this issue with an example:
You write a software and you will add a feature to Copy function. For example, you will add filtering feature additionally to CTRL+C.
With the example above I need to clarify issues below:
1. If our new feature for "filtering for the copy command" is protected with a patent, is there exists a possible patent violation if we use the same feature in our software?
2. If yes, how can we figure out that our new "filtering for the copy command" can cause a patent violation?
3. Another Case related to above:
Case: No one ows patent right for the feature and you add this feature first to your software. Is there a possible risk such as: Another guy applies for patent of this feature, and if he get the patent for it could your software start to violate the patent then?
4. Can such small features like above "filtering for the copy command" can be patented? If yes a software developer should worry with the patent violation issue in addition to design and development.
You have definitely heard patent violation cases between big software companies but they have departments for patent searching, lawyer teams etc. But if you are only a small software development team there are not only no one to carry out that kind of patent issues, but also your sources are insufficent.

This doesn't seem to be a problem when using `ZipFile(filename)`, but perhaps it's problematic when passing `ZipFile` a file-like object, because of some implementation details in the `zipfile` module?

Class books_Controller{
static function up(){
//create sql database tables;
}
static function down(){
// delete cuurent db table
}
}
Then I call to up to create the tables and down to remove.
books_Controller::up();
Thats great except when setting up a new server it can become a hastle creating and updating an 'init.php' file. Also sites new specific things on a per site basis.
## Proposal
I've thought about creating a simple online php terminal. For example, I could visit domain.com/terminal, enter username and password and be able to eval input. From there I could bring up and down only specific along with other maintence. Pros? Cons?
I don't hate sql, but I find it troublesome to manage/update up to date sql files. Also abstractions are near impossible in sql. | php | null | null | null | null | 06/28/2011 21:39:34 | not constructive | PHP SQL Table Creation and Maintance

What I'm trying to do is store a hierarchical menu in an acts_as_tree data table (done). In application_helper.rb, I create an html menu by querying the database and walking the tree (done). I don't want to do this for every page load.
Here's what I tried:
application.rb
config.menu = nil
application_helper.rb
def my_menu_builder
return MyApp::Application.config.menu if MyApp::Application.config.menu
# All the menu building code that should only run once
MyApp::Application.config.menu = menu_html
end
menu_controller.rb
def create
# whatever create code
expire_menu_cache
end
protected
def expire_menu_cache
MyApp::Application.config.menu = nil
end
Where I stand right now is that on first page load, the database is, indeed, queried and the menu built. The results are stored in the config variable and the database is never again hit for this.
It's the cache expiration part that's not working. When I reset the config.menu variable to nil, presumably the next time through my_menu_builder, it will detect that change and rebuild the menu, caching the new results. Doesn't seem to happen.
Questions:
Is Application.config a good place to store stuff like this?
Does anyone see an obvious flaw in this caching strategy?
Don't say premature optimization -- that's the phase I'm in. The premature-optimization iteration :)

Should following code give warning?
class Foo { public void Do() { /*...*/ } /*...*/ }
class Bar : Foo { public static void Do() { /*...*/ } /*...*/ }
It gives: "warning CS0108: 'Bar.Do()' hides inherited member 'Foo.Do()'. Use the new keyword if hiding was intended."
Let me make a change in code.

If you do following, warning goes away.

Let me make further change.
class Foo { public void Do() { /*...*/ } /*...*/ }
class Bar : Foo {
new public static void Do()
{ new Bar().Do();/*...*/ } /*...*/
}
This does not compile. error CS0176: Member 'Bar.Do()' cannot be accessed with an instance reference; qualify it with a type name instead.
So, I lose access to inherited method via instance reference from static method!

Everything works like a charm until the ipad is rotated to landscape and the page scroll view is zoomed a 33%.
All of the subviews are in their place. their bounds are correct, so as their frame. The thing is that when I swipe over the little galleries they don't scroll any more. The big page does.
I've tried setting canCancelContentTouches to NO to all of the involved scrollviews.
I also subclassed the gallery scroll view to get a grip on the touchesEnded/began/cancelled and try to disable the super view scrolling from there with no success.
I tried to set the galleries as a first responder when I called init on them. With no further results.
Now I can scroll the galleries only if I put my finger for a while on them, so no gesture recognizer steals the swipe from them, and then scroll gently to the next picture of the gallery.
If I swipe normally, sometimes the big outter scrollview would steal the swipe and change the page, and sometimes the little gallery would catch it first.
**this only happens when the scrollview containing the CA layer (the page) is zoomed** otherwise works amazingly great with no issues what so ever.
Am I screwing the UIResponder chain? How could I fix this?
I could paste you some code snippets, but this involves a handful of classes, that I don't know which ones could be of use or not.

String json = xstream.toXML(objPerson);
The order of the output json doesnt match the same order I have in class Person, in other words, the last name (lname) comes before the first name (fname).
Anyone know why that happnes? Can it be controlled?
Supposing we have a list of elements, and I sort it, can I rely that Xstream will convert the list to json and keep the sorting order as it is in the java code?

Some of the images are fine and he can upload but there are a quite a few which he can't.
When he clicks to browse the folder it comes up but the images aren't there.
It doesn't seem to be a mime issue or anything to do with the extension being capitals.
The files seem to be a range of sizes as well so that doesn't help.
I've asked the user to update his system and browser same problem. He has tried several different browsers and has also updated his flash.
Doesn't seem to be a virus or anything nasty.
Does anyone know of any other steps I could take.
I would like to try this out myself but we only have windows and a mac and a command based lunix server and he is on Ubuntu 11.10 - Oneiric Ocelot
Any ideas?
Thanks

(Converting `float` to `int`, mask sign bit, convert back for absolute value, instead of just calling `fabs()`, for example)
Nowadays is almost always better to just use the standard library math functions, since these tiny things are hardly the cause of most bottlenecks anyway.
But I still want to do a comparison, just for curiosity's sake. So I want to make sure when I profile, I'm not getting skewed results. As such, I'd like to make sure the compiler does not optimize out statements that have no side effect, such as:
void float_to_int(float f)
{
int i = static_cast<int>(f); // has no side-effects
}
Is there a way to do this? As far as I can tell, doing something like `i += 10` will still have no side-effect and as such won't solve the problem.
The only thing I can think of is having a global variable, `int dummy;`, and after the cast doing something like `dummy += i`, so the value of `i` is used. But I feel like this dummy operation will get in the way of the results I want.

All the other browsers now support it... except Firefox.
The Firefox developers have been [arguing over it since 2005](https://bugzilla.mozilla.org/show_bug.cgi?id=312156) but despite the obvious demand for it, they can't seem to actually bring themselves to implement it (even an experimental `-moz-` implementation would be sufficient).
A few years ago, someone worked out a way to [hack Firefox 3 to make it support an ellipsis](http://ernstdehaan.blogspot.com/2008/10/ellipsis-in-all-modern-browsers.html). The hack uses the `-moz-binding` feature to implement it using XUL. Quite a number of sites are now using this hack.
The bad news? Firefox 4 is removing the `-moz-binding` feature, which means this hack won't work any more.
So as soon as Firefox 4 is released (later this month, I hear), we're going to be back to the problem of having it not being able to support this feature.
So my question is: Is there any other way around this? (I'm trying to avoid falling back to a Javascript solution if at all possible)

I have a url, something like this `localhost:8080/foo.action?param1=7¶m2=8¶m3=6`
When this is the Url (as it is), `request.getParmeter("param2")` gives me `8` [Correct]
i) When the encoding converts this url to `localhost:8080/foo.action?param1=7%26param2=8%26param3=6`
In this case, `request.getParameter("param1")` gives me `7¶m2=8¶m3=6`

I'm using pyparsing to parse vcd (value change dump) files. Essentially, I want to read in the files, parse it into an internal dictionary, and manipulate the values.
Without going into details on the structure, my problem occurs with identifying nested categories.
In vcd files, you have 'scopes' which include wires and possibly some deeper (nested) scopes. Think of them like levels.
So in my file, I have:
$scope module toplevel $end
$scope module midlevel $end
$var wire a $end
$var wire b $end
$upscope $end
$var wire c $end
$var wire d $end
$var wire e $end
$scope module extralevel $end
$var wire f $end
$var wire g $end
$upscope $end
$var wire h $end
$var wire i $end
$upscope $end
So 'toplevel' encompasses everything (a - i), 'midlevel' has (a - b), 'extralevel' has (f - g), etc.
Here is my code (snippet) for parsing this section:
scope_header = Group(Literal('$scope') + Word(alphas) + Word(alphas) + \
Literal('$end'))
wire_map = Group(Literal('$var') + Literal('wire') + Word(alphas) + \
Literal('$end'))
scope_footer = Group(Literal('$upscope') + Literal('$end'))
scope = Forward()
scope << (scope_header + ZeroOrMore(wire_map) + ZeroOrMore(scope) + \
ZeroOrMore(wire_map) + scope_footer)
Now, what I _thought_ happens is that as it hits each scope, it would keep track of each 'level' and I would end up with a structure containing nested scopes. However, it errors out on
$scope module extralevel $end
saying it expects '$upscope'.
So I know I'm not using the recursion correctly. Can someone help me out? Let me know if I need to provide more info.
Thanks!!!!

For the past few days, I've had the following issues with Chrome:
1) I cannot tab between fields on a form
2) Auto-fill does not show up in forms
3) I need to press the return key twice to get a new line (for example, in this text box).
I've uninstalled all of my extensions, in case that was the issue, but it didn't help. I've written to the support team, but haven't heard back.
If this keeps up, I may need to switch back to Firefox.
