  • Are there design-time watch windows for Visual Studio 2008/2010?

    - by Jeff
    There are many times when I need to test a little snippet of .net code but rebuilding and publishing the entire project or writing a suite of unit tests just seems like overkill. For example, I am writing a regular expression right now and I want to see if it the pattern is matching on the right parts. I could go and find a million other utilities that do that sort of thing, but that is not exactly my point. FireBug has an exact analogue to what I want - the FireBug console. There is a text box where the user can enter some JavaScript and FireBug will execute it on the spot and display the return value. I would love to be able to enter something like (new Regex("b+")).Replace("abc", "x") and see the results without having to do all the overhead. Does VS have anything like this?

  • synchronizing reads to a java collection

    - by jeff
    so i want to have an arraylist that stores a series of stock quotes. but i keep track of bid price, ask price and last price for each. of course at any time, the bid ask or last of a given stock can change. i have one thread that updates the prices and one that reads them. i want to make sure that when reading no other thread is updating a price. so i looked at synchronized collection. but that seems to only prevent reading while another thread is adding or deleting an entry to the arraylist. so now i'm onto the wrapper approach: public class Qte_List { private final ArrayList<Qte> the_list; public void UpdateBid(String p_sym, double p_bid){ synchronized (the_list){ Qte q = Qte.FindBySym(the_list, p_sym); q.bid=p_bid;} } public double ReadBid(String p_sym){ synchronized (the_list){ Qte q = Qte.FindBySym(the_list, p_sym); return q.bid;} } so what i want to accomplish with this is only one thread can be doing anything - reading or updating an the_list's contents - at one time. am i approach this right? thanks.

  • Date or String declaration in a javabean

    - by Jeff
    Should I declare an attribute in a javabean that holds a date value a user types in on an HTML form as a String or Date? I feel I should declare as a Date, however, since I do server validation on all form data, if the date doesn't validate, when I pass the form bean back to the jsp view for correcting, I lose the date value that the user tried to type in. If I declare as a String, if the date doesn't validate, I'm able to set the string value in the bean and pass the bean back to the view and the user can see what they incorrectly typed. But with a String declaration for Date inputs I forsee problems down the road with my DAO. I want to be able to use a DAO utility which generates a prepare statement using setObject. In my html form I request dates to be mm/dd/yyyy and in DAO i'm using Oracle Date. I can not use hibernate or such, since this is a corporate intranet. What is the best practice "pattern" I should be following??

  • Any GUI libaray for iPhone & Andriod based on OpenGL ES?

    - by Jeff
    Since both iPhone and Android support OpenGL ES, is there any open source or commercial GUI library we can use for these two platforms? Or is it doable (or how difficult) to port an application from one to another platform? As I know, for iPhone only, libNUI (http://www.libnui.net) is a good choice (dynamic layout & mature), but it only provides GPL & commercial license. Any other open source tool similar with libNUI?

  • C# change e-mail 'from' address to a user-provided one.

    - by Jeff
    We have an app that allows users to send e-mails from our system. It allows the user to specify their e-mail address, and gives them several standard templates to use as a starting point for their e-mail. When we send the e-mails, we use the address they provided as the 'reply-to', but the 'from' address of the e-mail (naturally) looks like our system (from '[email protected]'). Is there a way to change this without getting tangled up in spam filters or automatic blocking? We'd prefer not to confuse the recipient as to who actually composed the e-mail they've received.

  • question on src folders in eclipse

    - by Jeff Colapietro
    So, I've been doing android application tutorials and everytime I create a package, for example the helloAndroid tutorial is com.example.android. When it saves this to src it creates a folder for com, another for example and one last one for android. So it gives me the error "class com.example.android does not exist" because its broken into different folders. If anyone can help me out please email me at: [email protected] Thank you very much.

  • How to publish to Facebook fan/business pages (not user profiles)

    - by Jeff Putz
    I'm trying to figure out if fan/business pages are conceptually similar to regular user pages. My end goal is to publish events from a third-party Web site (new content, announcements, etc.) into the FB page that promotes the third-party site. I'm not sure where to start exactly. Been looking at the .NET Facebook SDK, and it seems focused on FB apps and authentication. Not sure where I should be looking. Help is appreciated!

  • image transistion

    - by Jeff Main
    Hi all. I've gotten stuck again. I've got an image (album cover) that I'll be changing in code behind, and wish to basicaly do the following. When a new album cover image is determine and aquired, I want the current image in the image control to fade out, get updated with the new cover, and then fade back in. I'm not seeing very many good examples on how to accomplish this in code behind. The following was my latest failed attempt... if (currentTrack != previousTrack) { BitmapImage image = new BitmapImage(); image.BeginInit(); image.CacheOption = BitmapCacheOption.OnLoad; image.CreateOptions = BitmapCreateOptions.IgnoreImageCache; image.UriSource = new Uri(Address, UriKind.Absolute); image.EndInit(); Storyboard MyStoryboard = new Storyboard(); DoubleAnimation FadeOut = new DoubleAnimation(); FadeOut.From = 1.0; FadeOut.To = 0.0; FadeOut.Duration = new Duration(TimeSpan.FromSeconds(.5)); MyStoryboard.Children.Add(FadeOut); Storyboard.SetTargetName(FadeOut, CoverArt.Name); Storyboard.SetTargetProperty(FadeOut, new PropertyPath(Rectangle.OpacityProperty)); CoverArt.Source = image; DoubleAnimation Fadein = new DoubleAnimation(); Fadein.From = 0.0; Fadein.To = 1.0; Fadein.Duration = new Duration(TimeSpan.FromSeconds(.5)); MyStoryboard.Children.Add(Fadein); Storyboard.SetTargetName(Fadein, CoverArt.Name); Storyboard.SetTargetProperty(Fadein, new PropertyPath(Rectangle.OpacityProperty)); MyStoryboard.Begin(this); } I'd prefer to do this in code behind simply because that is where I'm aquiring the image. Otherwise, I'm not sure how I'd trigger it. An example would be greatly appriciated. Thanks.

  • I need an OpenOffice Calc formula to fetch the Google PageRank for the top 5 listed results of a giv

    I have a list of search terms: A | B | C | D | E | _______________________________________________________________ 1 | SEARCH TERM PR #1 PR #2 PR #3 PR #4 2 | lcd screens 3 | mud 4 | eurpoean sport cars 5 | perfume How can the search term in my spreadsheet fetch the Google PageRank of the top five domain/page results for each term? I've seen similar "pagerank fetching" questions here, but those are based on known domains. In my scenario, the domain is unknown until results are fetched based on a search term.

  • Question about software that tracks divs better than notepad++

    - by Jeff
    I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

  • ios - almost there with updating Core Data

    - by Jeff Kranenburg
    I have been following the answer of this question: How to update existing object in core data? and in the answer it comes across this line of code to update a record within the array: Favorits* favoritsGrabbed = [results objectAtIndex:0]; Now this updates whatever is set a record 0 of the database, no matter what cell I select to edit. I am sorry but I cannot figure out how to change it into updating the cell I have selected. Starting to grow grey hairs here:-) The problem (maybe it is my mindset) is that I am required to give an integer and I am unable to find something to substitute it. Any help would be great.

  • jquery filtering content before specific string

    - by jeff
    Is is possible remove all content before a specific string with jquery? For instance say I wanted to strip all the text before the word "subcommittee" in this example below. How would I do that? With losses mounting among hoteliers, fishermen and others whose livelihoods have been curtailed by the spill, frustration is "rapidly escalating" along the Gulf Coast alive." Linn told a House Energy and Commerce subcommittee Monday that the amount of money BP has paid local residents for their losses has typically been about $5,000, a sum he dismissed as "a marketing ploy." Businesses such as his vacation rental company are borrowing money to pay their overhead costs, which he called "the only way we're going to keep our business alive."

  • How can I treat a sequence value like a generated key?

    - by Jeff Knecht
    Here is my situation and my constraints: I am using Java 5, JDBC, and DB2 9.5 My database table contains a BIGINT value which represents the primary key. For various reasons that are too complicated to go into here, the way I insert records into the table is by executing an insert against a VIEW; an INSTEAD OF trigger retrieves the NEXT_VAL from a SEQUENCE and performs the INSERT into the target table. I can change the triggers, but I cannot change the underlying table or the general approach of inserting through the view. I want to retrieve the sequence value from JDBC as if it were a generated key. Question: How can I get access to the value pulled from the SEQUENCE. Is there some message I can fire within DB2 to float this sequence value back to the JDBC driver?

  • Nhiberate, multiple tables, same class

    - by jeff
    It's been asked a million times, its like this. Say Invoice is the base class and InvoiceHistory is the class that simply inherits from Invoice. When I do something like invoiceList = session.CreateCriteria(typeof(Invoice)).List(); I get everything from Invoice (that I want, plus everything from InvoiceHistory). Do I need to have an InvoiceBase and create derived versions for Invoice and InvoiceHistory?

  • Parameterizing a SQL IN clause?

    - by Jeff Atwood
    How do I parameterize a query containing an IN clause with a variable number of arguments, like this one? select * from Tags where Name in ('ruby','rails','scruffy','rubyonrails') order by Count desc In this query, the number of arguments could be anywhere from 1 to 5. I would prefer not to use a dedicated stored procedure for this (or XML), but if there is some fancy SQL Server 2008 specific way of doing it elegantly, I am open to that.

  • How to combine Option values in Scala?

    - by Jeff
    Hi! I want to be able to apply an operation f: (T,T) => T to two Option[T] values in Scala. I want the result to be None if any of the two values is None. More specifically, I want to know if is there a shorter way to do the following: def opt_apply[T](f: (T,T) => T, x: Option[T], y: Option[T]): Option[T] = { (x,y) match { case (Some(u),Some(v)) => Some(f(u,v)) case _ => None } } I have tryied (x zip y) map {case (u,v) => f(u,v)} but the result is an Iterator[T] not an Option[T]. Any help will be appreciated. Thanks.

  • Passing a NSString to another ViewController using classes

    - by Jeff Kranenburg
    I know this insanely simple, but I am re-teaching myself the basics and trying to get my head around this:-) I have one ViewController called MainVC and I have one called ClassVC In ClassVC I have this code: @interface ClassVC : UIViewController { NSString *mainLine; } @property (nonatomic, retain) NSString *mainLine; @end and I have this in the implementation file: @synthesize mainLine = _mainLine; -(NSString *)_mainLine { _mainLine = @"This a string from a Class"; return _mainLine; } Now I was thinking that if I #import the ClassVC into MainVC I would be able to transfer that string along as well like so: This code is in the viewDidLoad _mainLabel.text = _secondClass.mainLine; NSLog(@"%@", _secondClass.mainLine); But that is not working - so cannot I not pass strings in through this way???

  • Apache RewriteRule not rewriting as expected

    - by Jeff
    Can you any one see anything wrong with the following apache rewrite rule: This is in my .htaccess file inside a folder called "text" a subdirectory of localhost/lombardpress I have the following rule Options +FollowSymlinks RewriteEngine on RewriteRule ([^/]+) /textdisplay.php?fs=$1 [NC] I was expecting this input: http://localhost/lombardpress-dev/text/lectio1 to rewrite to this: http://localhost/lombardpress-dev/text/textdisplay?fs=lectio1 But instead I get a 404 error. The requested URL /textdisplay.php was not found on this server. It looks to me like the RewriteRule has re-written the address but not as I intended - so there must be something wrong with my regular expression. Let me know if I can provide further information.

  • SQL Modify question

    I need to replace a lot of values for a Table in SQL if the inactivity is greater then 30 days. I have UPDATE VERSION SET isActive = 0 WHERE customerNo = ( SELECT c.VersionNo FROM Activity b INNER JOIN VERSION c ON b.VersionNo = c.VersionNo WHERE (Months_between(sysdate, b.Activitye) > 30) ); It only works for one value though, if there is more then one returned it fails. What am I missing here? If someone could educate me on what is going on, I'd also appreciate it.
