• Changing the image of a scroll bar without flash.

  - by user352527

  How can i change the appearance (not the color) of a scrollbar within a box with overflow? I know how to do it in flash, I need a way to do it without it. In fact, I want to know how they did this slider in the apple web site: http://www.apple.com/mac/ It seems they used css along with javascript, but that's all I know. Is it possible that they did it using DOM, DHTML, HTML 5, Ruby or PHP? I have no idea. If you'd be kind enough to share the answer, I thank you in advance.

• How to set html content in Moodialog

  - by Diego

  Hello, i've just downloaded Moodialog, a Mootools plugin for dialog, but i have a problem. If content is set via parameters it will be text and not html. Can you help me change the function to accept html? I suppose that this is the code to be edit. setContent: function(){ var content = Array.from(arguments); if (content.length == 1) content = content[0]; this.content.empty(); var type = typeOf(content); if (['string', 'number'].contains(type)) this.content.set('text', content); else this.content.adopt(content); return this; }, I tried to edit 'text' in 'html', but it will not work. Thanks for help (and sorry for my bad english).

• JQuery display problems?

  - by DuH

  I'm new to JQuery and was wondering how can I have Changes saved! displayed only once even if the user presses the submit button multiple times for example if a user decides to change there info three different times the text, Changes saved!Changes saved!Changes saved! is displayed i only want Changes saved! displayed once. How can I fix this problem? What part of my code needs to be fixed? Here is the JQuery code. $(function() { $('#changes-saved').hide(); $('.save-button').click(function() { $.post($('#contact-form').attr('action'), $('#contact-form').serialize(), function(html) { $('div.contact-info-form').html(html); $('#changes-saved').append('Changes saved!').show(); }); $('a').click(function () { $('#changes-saved').empty(); $('#changes-saved').hide(); }); return false; // prevent normal submit }); });

• iframe/lightbox refresh issues

  - by user96828

  Hi Please check out: http://gherkin.co.nz/refresh/ and click on the purple box that says 'Membership chest' You should then see some form fields in an iframe in the lightbox. If you click on the "GO" button, the page will change (currently Not found, which is fine for now). If you click the dark area to close the box, then click the purple card again - it will take you back to the not found page. When called, I want the content to always go back to the page specified in the iframe src, not the last page. Can it go back to the first specified page on this second click? Does that make sense? basically I want the iframe/lightbox to refresh its content each time it is called.

• Editing a UIViewController from another class.

  - by Guy

  I am trying to programmatically change the user interface of a UIViewController from another NSObject class. The problem is that I am unsure of how to access the UIViewController's view from the NSObject class. So for example, in my NSObject class, I say something like: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; self.view.backgroundColor = [UIColor yellowColor]; but I keep getting errors saying "Request for member "view" in something not a strut or union." Is there something I need to allow my NSObject class to see my UIViewController? Thanks!

• Very strange form behaviour

  - by musoNic80

  I can't work this out. One minute it was working fine and now it's not and I can't see what's changed!! My problem is simply submitting a username and password for a login function. The form method is set to "post" but for some reason no data is getting through. If I dump $_REQUEST or $_POST they return empty. I know the form is submitting because if I change the method to "get" I receive the data as expected. Can anyone think of any reason why "get" would work when "post" isn't?!?!? If it's relevant, I'm using the codeigniter framework.

• Better performance to Query the DB or Cache small result sets?

  - by user169867

  Say I need to populate 4 or 5 dropdowns w/ items from a database. Each drop down will have < 15 items in it. These items almost never change. Now I could query the DB each time the page is accessed or I could grab the values from a custom class that would check to see if they already exist in ASP.Net's cache and only if they don't query the DB to update the cache. It's trivial for me to write but I'm unsure if the performace would be better or not. I think it would be (although not likely anything huge). What do you think?

• What is the difference between a constructor and a procedure in Delphi records?

  - by HMcG

  Is there difference in behavior between a constructor call and a procedure call in Delphi records? I have a D2010 code sample I want to convert to D2009 (which I am using). The sample uses a parameterless constructor, which is not permitted in Delphi 2009. If I substitute a simple parameterless procedure call, is there any functional difference for records? I.E. TVector = record private FImpl: IVector; public constructor Create; // not allowed in D2009 end; becomes TVector = record private FImpl: IVector; public procedure Create; // so change to procedure end; As far as I can see this should work, but I may be missing something.

• Track/Display Array Index As Part Of Cout (C++)

  - by John Smith

  Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

• Programmatically selecting file in explorer

  - by flashk

  In my application I can programmatically open explorer and select a file using the following code: void BrowseToFile(LPCTSTR filename) { CString strArgs; strArgs = _T("/select,\""); strArgs += filename; strArgs += _T("\""); ShellExecute(0, _T("open"), _T("explorer.exe"), strArgs, 0, SW_NORMAL); } My problem is that if I call this function a second time with a different file, but in the same folder, the selection in explorer does not change to the new file, but remains on the previous file. For example, if I call my function with C:\path\to\file1.txt, a new explorer window will open and file1.txt will be selected. If I call my function a second time with C:\path\to\file2.txt, the existing explorer window will be activated, but the selection will still be on file1.txt. Is there a way to force explorer to update the selection or a better way to accomplish this?

• Save VM properties with EF code first

  - by Julien

  I thought this would be simple but can't find any good examples. public Class BookVm : ImplementsPropertyChanged { public int BookId {get;set;} private bool _favorite; public bool Favorite { get { return _favorite; } set { _favorite = value; OnPropertyChanged("Favorite"); MyDbContext.SaveChanges() // this does not work } } Then in my XAML bound to Book <CheckBox Content="Favorite" IsChecked="{Binding Favorite}" /> How and when do I call SaveChanges() on my DatabaseContext? I don't want to implement a save button. If I intercept the PropertyChange event and call SaveChanges, nothing seems to happen. My object is modified in memory but the database does not see a change. My BookVm class is created on application startup like so: foreach (var book in MyDbContext.Books) Books.Add(book); Where Books is an ObservableCollection<Book> in my MainWindowVm

• Binding to 'To' In Storyboard

  - by Peanut

  I'll try to make this as simple as I can. I want to do this: <Storyboard x:Name="MoveToLocation"> <DoubleAnimation Duration="0:0:0.5" To="{Binding X}" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="grid" d:IsOptimized="True"/> </Storyboard> As you may have noticed the Binding on 'To' Property does not work. It seems to only accept static values. How does one do this animation with MVVM? I cant just put in static data, cause it's going to change. Thanks.

• Hibernate or JPA or JDBC or ???

  - by Yatendra Goel

  I am developing a Java Desktop Application but have some confusions in choosing a technology for my persistence layer. Till now, I have been using JDBC for DB operations. Now, Recently I learnt Hibernate and JPA but still I am a novice on these technologies. Now my question is What to use for my Java Desktop Application from the following? JPA Hibernate JDBC DAO any other suggestion from you... I know that there is no best choice from them and it totally depends on the complexity and the requeirements of the project so below are the requirements of my project It's not a complex application. It contains only 5 tables (and 5 entities) I wan't to make my code flexible so that I can change the database later easily The size of the application should remain as small as possible as I will have to distribute it to my clients through internet. It must be free to use in commercial development and distribution.

• How can I see what capybara found in a failing cucumber step?

  - by ajmurmann

  I started migrating from cucumber + webrat to cucumber + capybara. Now the behavior of "I should see " seems to be somewhat different. Most of these fail now, although I didn't change anything on the page. I replaced the snippet that should be found with some stuff that is on every page and for some text it works and for other text it doesn't. I can't find any pattern in what is found in the page's content and what is not. Webrat used to print what the page content is that it found, in case it did not contain the required phrase. Is there anyway to have capybara show what text it got from the page in which it tried to find the text?

• proper Django ORM syntax to make this code work in MySQL

  - by gtujan

  I have the following django code working on an sqlite database but for some unknown reason I get a syntax error if I change the backend to MySQL...does django's ORM treat filtering differently in MySQL? def wsjson(request,imei): wstations = WS.objects.annotate(latest_wslog_date=Max('wslog__date'),latest_wslog_time=Max('wslog__time')) logs = WSLog.objects.filter(date__in=[b.latest_wslog_date for b in wstations],time__in=[b.latest_wslog_time for b in wstations],imei__exact=imei) data = serializers.serialize('json',logs) return HttpResponse(data,'application/javascript') The code basically gets the latest logs from WSlog corresponding to each record in WS and serializes it to json. Models are defined as: class WS(models.Model): name = models.CharField(max_length=20) imei = models.CharField(max_length=15) description = models.TextField() def __unicode__(self): return self.name class WSLog(models.Model): imei = models.CharField(max_length=15) date = models.DateField() time = models.TimeField() data1 = models.DecimalField(max_digits=8,decimal_places=3) data2 = models.DecimalField(max_digits=8,decimal_places=3) WS = models.ForeignKey(WS) def __unicode__(self): return self.imei

• Can I use Visual Studio 2010's C++ compiler with Visual Studio 2008's C++ Runtime Library?

  - by BillyONeal

  I have an application that needs to operate on Windows 2000. I'd also like to use Visual Studio 2010 (mainly because of the change in the definition of the auto keyword). However, I'm in a bit of a bind because I need the app to be able to operate on older OS's, namely: Windows 2000 Windows XP RTM Windows XP SP1 Visual Studio 2010's runtime library depends on the EncodePointer / DecodePointer API which was introduced in Windows XP SP2. If using the alternate runtime library is possible, will this break code that relies on C++0x features added in VS2010, like std::regex?

• How do I test how my client program will react to a web server error?

  - by Brad Bruce

  I have a client program based on LibCurl. I have run into a situation where on some occasions a program on the server runs longer than the configured IIS timeout. IIS then terminates the program and returns a 502 error status to the client. I have added code to the client to capture this issue. Now, I need to find a way to prove that the change will work. I haven't been able to reliably reproduce the issue, so don't have a good test case. Any suggestions?

• What is the fastest way to trim blank lines from beginning and end of array?

  - by Edward Tanguay

  This script: <?php $lines[] = ''; $lines[] = 'first line '; $lines[] = 'second line '; $lines[] = ''; $lines[] = 'fourth line'; $lines[] = ''; $lines[] = ''; $lineCount = 1; foreach($lines as $line) { echo $lineCount . ': [' . trim($line) . ']<br/>'; $lineCount++; } ?> produces this output: 1: [] 2: [first line] 3: [second line] 4: [] 5: [fourth line] 6: [] 7: [] What is the fastest, most efficient way to change the above script so that it also deletes the preceding and trailing blank entries but not the interior blank entries so that it outputs this: 1: [first line] 2: [second line] 3: [] 4: [fourth line] I could use the foreach loop but I imagine there is a way with array_filter or something similar which is much more efficient.

• ASP.NET TextBox verses input type="text" behavior

  - by harrije

  I notice with ASP.NET if the server side control TextBox is used with out autopostback it will not submit (or postback) the form when typed text ends with enter, which is different from the behavior for plain old HTML pages. Fine, I can set autopostback to get the behavior I want after the enter key. However, autopostback will also cause submit (or postback) when the typed text does not end with enter but focus has changed (i.e. with tab or mouse click), which again is different from plain old HTML pages. How can I get an ASP.NET page to behave the same as a plain old HTML page with respect to text input regardless of whether enter key or change of focus occurs?

• iPhone: Chained views

  - by Michael

  I want to have dynamically created views and be able to scroll(change views like in camera roll) either from my program or user should also be able to do that. The views should contain only a simple text. Each view has to replace other, so they are like chained. The other example is the screenshots of applications in app store application details. I don't know which classes to check/start so if anyone can give me an idea of how this could be designed I would appreciate it.

• MSSQL choosing row (from group) with max value

  - by sriehl

  I have a large database and am putting together a report of the data. I have aggregated and summed the data from many tables to get two tables that look like the following. id | code | value id | code | value 13 | AA | 0.5 13 | AC | 2.0 13 | AB | 1.0 14 | AB | 1.5 14 | AA | 2.0 13 | AA | 0.5 15 | AB | 0.5 15 | AB | 3.0 15 | AD | 1.5 15 | AA | 1.0 I need to get a list of id's, with the code (sumed from both tables) with the largest value. 13 | AC 14 | AA 15 | AB There are 4-6 thousand records and it is not possible to change the original tables. I'm not too worried about performance as I only need to run it a few times a year.

• [Flex 4] Removing sort arrows from AdvancedDataGridColumn Header.

  - by zeroDivisible

  Hello, I am doing this simple project using Flex 4 SDK and I got stuck with this simple problem: I have turned sortable property for AdvancedDataGridColumn to false, but the column header is still rendered as: As You can see, my label for this header is "06", but the column header is divided and it keeps the place for sort arrow. How can I change this? I would like my column header to contain only my label. I know that most probably I need to do some magic with AdvancedDataGridHeaderRenderer but I just started learning Flex and would like to receive some help. Thank You for help. Best regards, Mike.

• Why would this line throw exception for type initializer failed?

  - by Jaggu

  I had a class: public class Constant { public static string ConnString = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString; } which would throw exception on LIVE: Type initialize failed for Constant ctor If I change the class to: public class Constant { public static string ConnString { get { return ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString; } } } it works. I wasted 2 hours behind this but I still don't know why would this happen. Any ideas? Note: The 1st class used to work on DEV environment but not on LIVE. The 2nd class works on DEV and also on Production. I am using VS2010 on production and Asp.Net 4.0 Website project. I am totally amazed by this inconsistency to say the least! Edit: This class was in App_Code folder.
