On iPhone simulator the cancel button on the tweet composer works fine and dismisses the view. However, on iPad simulator the cancel button does not work and the tweet composer view remains on the screen. It is even weirder because after pressing the cancel button, the keyboard retracts and the underlying views become active. It behaves as if the view has been dismissed but its is still there.
The code I used when the user pressed the action button is:
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex];
if ([buttonTitle isEqualToString:@"Open in Safari"]){
[[UIApplication sharedApplication] openURL:[self.webView.request URL]];
}else if ([buttonTitle isEqualToString:@"Twitter"]){
if ([TWTweetComposeViewController canSendTweet]){

[tweetSheet addURL:[self.webView.request URL]];
tweetSheet.completionHandler = ^(TWTweetComposeViewControllerResult result){
if (result == TWTweetComposeViewControllerResultCancelled){
[self dismissModalViewControllerAnimated:YES];
}
};
[self presentModalViewController:tweetSheet animated:YES];
}else {

Do you have any idea on how to solve this problem or is it a bug of the simulator?

(Don't bother lecturing me that I could do this in the table definition, I have second datetime field that is using that functionality already and you can only do it with one column per table.)
This trigger works great for my purposes:
CREATE TRIGGER foobar_insert

FOR EACH ROW SET NEW.created=NOW();
So whenever a new row is inserted, `foobar.created` gets set to the current time. This is great when I do something like:
> INSERT INTO foobar (foo) VALUES ('bar');
The only problem with this is that if I want to explicitly set `foobar.created` in the insert statement, it gets overridden by the trigger.
So,
> INSERT INTO foobar (foo,created) VALUES ('foo','2006-01-01 12:12:12');
results in `foobar.created` equaling the time of the insert, not the time specified in the insert statement.

| .net | sql-server-2008 | sdk | cognos | clrstoredprocedure | null | open | System.IO.FileNotFoundException when executing CLR Stored Procedure to run a Cognos Report
===
Good Morning. I am currently experiencing an issue with a CLR Stored procedure calling an assembly created in Visual Basic (VS 2008). At the highest level, the assembly executes a report contained in Cognos8 and moves the output to a specificed directory on the network. I have no issue when calling the method from a simple test EXE, but when I try to execute via the CLR stored procedure, I am getting the following:
Msg 6522, Level 16, State 1, Procedure ReportRunner, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "ReportRunner":
System.IO.FileNotFoundException: Could not load file or assembly 'cognosdotnetassembly_2_0, Version=10.1.4707.501, Culture=neutral, PublicKeyToken=d6e6d7d808b7e5b7' or one of its dependencies. The system cannot find the file specified.

I just watched your interview at MIX11 and and saw that you were implementing a universal lambda converter in your toolkit. I had implemented such a converter a while ago along with a version of the DynamicLibrary that works in Silverlight. You mentioned that you were still having issues getting that library to work. The video was a couple of weeks old, but if you are still having issues, I can send the code to you.

Laurent,
I just watched your interview at MIX11 and and saw that you were implementing a universal lambda converter in your toolkit. I had implemented such a converter a while ago along with a version of the DynamicLibrary that works in Silverlight. You mentioned that you were still having issues getting that library to work. The video was a couple of weeks old, but if you are still having issues, I can send the code to you.

Obviously in C# any variable has to be new'd, so it wouldn't be deleted until the next garbage collection cycle, and if you immediately create a new classlet, you could have an out-of-sync logger.
How would people try to solve this problem in C#? I want the logger syntax to be as unobtrusive to the current function as possible, and still support functions with multiple exit points.

I am trying to highlight a set of keywords using javascript and regex, I facing one problem, my keyword may contain literal and special characters as in @text #number etc. I am using word boundary to match and replace the whole word and not a partial word (contained within another word).
var pattern = new regex('\b '( + keyword +')\b',gi); here this expression matches the whole keywords and highlights them, however incase if any keyword like "number:" do not get highlighted.
I am aware that \bword\b matches for a word boundary and special characters are non alphanumeric characters hence are not matched by the above expression.
Can you let me know what regex expression I can use to accomplish the above.
thanks,
Bhupen*
hi,
For the above I tried Tim Pietzcker suggestion for the below regex,
expr: (?:^|\\b|\\s)(" + keyword + ")(?:$|\\b|\\s)
the above seems to be working for getting me a match for the whole word with alphanumeric and non alphanumeric characters, however whenever a keyword has consecutive html tag before or after the keyword without a space, it does not highlight that keyword (e.g. social security ****number:**< br >**).
I tried the following regex, but it replaces the html tag preceding the keyword
expr: (?:^|\b|\s|<[^>]+>)number:(?:$|\b|\s|<[^>]+>)
Here for the keyword **number:** which has "< br >" (space added intentionally for br tag to avoid browser interpreting the tag) coming next without space in between gets highlighted with the keyword.
Can you suggest an expression which would ignore the consecutive html tag for the whole word with both alphanumeric and non alphanumeric characters.

Basically I am asking if there is an engineering mode available that would allow for me to turn off A5/1 encryption (use A5/0 or A5/2) on any of the phones we have been given for testing so that they can be used with the other equipment that we have? Our equipment does not allow the "network" to disable encryption and our network cannot support A5/1 or A5/3.
I'd greatly appreciate any help. We have:
Nokia N75
Nokia N95
Nokia N900
Nokia 7610
Nokia E61i
HTC Excalibur (S620/S621)
HTC Vox (S710)
HTC Startrek (Qtek 8500)
ETEN Glofiish X500
Can we do that on any of these phones? These are simply the older phones that people have donated for the project. If we have a bad sample of phones, can you suggest any models that allow for this? My first goal is get it working for GSM/GPRS but then I am supposed to get it working for UMTS (W-CDMA) too.
Thank you and regards,

Here's what I have.
In the View (a DataGrid to be specific):
<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectionChanged" >
<cmnwin:InvokeDelegateCommandAction
Command="{Binding SelectedExcludedItemChangedCommand}"
CommandParameter="{Binding RelativeSource={RelativeSource self}, Path=SelectedItems}" />

</i:Interaction.Triggers>
In the ViewModel:
public DelegateCommandWithParameter SelectedActiveItemChangedCommand
{
get
{
return selectedActiveItemChangedCommand ??
(selectedActiveItemChangedCommand = new DelegateCommandWithParameter(DoSelectedActiveItemsChanged, CanDoSelectedActiveItemsChanged));
}
}
public bool CanDoSelectedActiveItemsChanged(object param)
{
return true;
}
public void DoSelectedActiveItemsChanged(object param)
{
if (param != null && param is List<Object>)
{
var List = param as List<Object>;
MyLocalField = List;
}
}
The new kind of DelegateCommand that allows me to pass objects as args:
public class DelegateCommandWithParameter : ICommand
{
#region Private Fields
private Func<object, bool> canExecute;
private Action<object> executeAction;
private bool canExecuteCache;

this.executeAction = executeAction;
this.canExecute = canExecute;
}

#region ICommand Members
public bool CanExecute(object parameter)
{
bool temp = canExecute(parameter);
if (canExecuteCache != temp)
{
canExecuteCache = temp;
if (CanExecuteChanged != null)
{
CanExecuteChanged(this, new EventArgs());
}
}
return canExecuteCache;
}
public event EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
executeAction(parameter);
}
#endregion
}
Whenever my code gets to the DoSelectedActiveItemsChanged, the arg is always NULL.... am I being a complete doofus here? Where does the CommandParamter get linked to the command args? AKA, why does the View pass nothing back to the command. Please help.

At the same time, I think the iPad version should not be the iPhone version writ large. A different UI is certainly warranted to most cases, but there will be spots where you want to reuse a dialog, or a whole view hierarchy.
So, I ask the community. What are some good practices to follow to ensure that my app can be universal with minimal tweaks? | 4 |

In a [previous exercise][1] I created a JSF web application that simulates the roll of two dice. The output after each page refresh looks something like this:
> On your third throw you have thrown a 3 and a 6.
Now, I want to create an application similar to that, except that both dice and the throw counter will be displayed as images. The throw counter must display values in range 1 to 9.
I am not very experienced in jsf, hence I am asking for some advice as to how to get started with this exercise. If you could help, that would be much appreciated. Thanks!

The template page for creating new articles is the same as the template page for editing existing articles. The only difference is that the form for editing has default/existing values added to it already.
I'm trying to figure out how to use the same action for both routes. Here are my routes:
article_new
url: /article/new/
class: sfDoctrineRoute
options:
model: MyArticle
type: object
param:
module: article
action: edit
article_edit
url: /article/edit/:id/
class: sfDoctrineRoute
options:
model: MyArticle
type: object
param:
module: article
action: edit
requirements:
id: /d+
So both articles point to the following action:
public function executeEdit(sfWebRequest $request)
{
$article = $this->getRoute()->getObject();
$this->form = new MyForm( $article );
// Binding and validation stuff here
// .....
}
This works great when you want to edit an article. `getRoute()->getObject()` automatically get the correct article for you from the `id` slug and passes those values as defaults into the form. Perfect.
But with the `article_new` route, it doesn't work so well. The `getRoute()->getObject()` returns the first article in my database table, even though I didn't feed the url any type of `id` parameter. So the information from the first article in the database gets passed as default values into the form. I obviously don't want this.
I also tried removing the `class: sfDoctrineRoute` stuff from the `article_new` route but then `getRoute()->getObject() fails because it's no longer an `sfRoute` object that I'm working with.
What is the best approach here? I'd like to do everything in one action just to save programming time and future maintenance time.
Also I found that one solution is that I can check to see if `$request->getParameter('id')` is `null` and if so, then `$article = array()`, else the article is retrieved using the `getRoute()->getObject()`. That seems to work fine but I figured there might be less hacky solution. | php | symfony | symfony-forms | null | null | null | open | Symfony: How to use same action for CREATE and UPDATE?

SQL? | I have looked on this site, googled, and even searched adobe developer central, without luck. As such, I think I might not know the correct terminology to search for, as my question is pretty straight-forward. Thus, if the title was misleading I apologize.
I'd like to learn how to create an HTML template which will then insert variables as needed, specifically, the names of cities and states (for a franchise), where it is appropriate.
Not to be too broad but I am a "front-end" web designer yet I am familiar (but not comfortable) with dynamic languages. This seems like it'd be very simple with what I know of PHP and MySQL, and I prefer (I view it as support) open-source technologies, but not at the expense of performance (I have read that PHP doesn't support UTF-8). I don't know much about ColdFusion but some stuff on Adobe's forums seemed like it was along the right lines...
In short, what I am getting at, is I'd like to know how to do this but also, if--for now--I am going to start with learning one dynamic language, what are the pros and cons of them (same for database technology). This may seem contradictory to my previous statement, but being a beginner, it would be awesome if you could recommend one that is "easier" to learn than another.
Basically, I'm asking for people more familiar with this to make a judgement call and give me some guidance...trying to figure everything out myself is making me prematurely old--either that or the 80+ hour weeks.

At first, my code was set up to default to using local storage, and if there is no local storage, then default to cookies.
However, in a few contexts (too complicated to go into here), that is not working, so I want to see if I can go the other way: default to using cookies, and if cookies aren't possible, use local storage.
Really, it's only Android that is having trouble with cookies, so basically if my code is being used on an Android device, then I want to switch to local storage.
In any case, here is the code for setting cookie/local storage data that I have, but it's not working:
function setCookie(c_name, value, expiredays)
{
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = c_name + "=" + escape(value) +
((expiredays === null) ? "" : ";expires=" + exdate.toUTCString());
if(document.cookie.length < 1 && typeof localStorage != "undefined")
{
localStorage.setItem(c_name, value);
}
}
I think the problem might be where it says `document.cookie.length < 1`. Is that a reliable way of seeing if cookies are being set? Part of the problem is I don't know why Android is rejecting my cookies, so I don't know what kind of response it's giving me (and debugging on the phone is not possible).

sudo apt-get install libc-client2007b libc-client2007b-dev
sudo apt-get install php5-imap
sudo /etc/init.d/apache2 start
When I run phpinfo(), I get the following imap values:
IMAP c-Client Version: 2004

Kerberos Support: enabled
Here's my sample code:
<?php
$connect_to = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$user = 'my gmail address';
$password = 'my gmail password';
$connection = imap_open($connect_to, $user, $password)
or die("Can't connect to '$connect_to': " . imap_last_error());
imap_close($connection);
?>
When I execute this code, I get the following output:
Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX in /var/www/clint/gmail/gmail.php on line 10

Note that I can telnet to imap.gmail.com:993 from this computer. I can also hookup Evolution (mail reader) to Gmail through IMAP and fetch mail without problems. So, I don't think this is a firewall issue. I'm pretty sure I've got something in PHP not setup correctly.
Any ideas?

imap_close($connection);
?>
When I execute this code, I get the following output:
Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX in /var/www/clint/gmail/gmail.php on line 10
Can't connect to '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX': TLS/SSL failure for imap.gmail.com: SSL context failed
Note that I can telnet to imap.gmail.com:993 from this computer. I can also hookup Evolution (mail reader) to Gmail through IMAP and fetch mail without problems. So, I don't think this is a firewall issue. I'm pretty sure I've got something in PHP not setup correctly.
Any ideas?
