  • Having a hard time implementing jquery serialScroll to a website. Need help!

    - by Martin Defatte
    Here's the page I am attempting to implement it on. www.yosoh.com/2010/advertising/beyond/ I have a custom script with figures out the width of all the images, adds it up, then sets the width of that page... I'd like to be able to set the arrows at the top to scroll to the next div (div.portfolioImage). I've followed Ariel Fischer's demo and documentation as best I can... but something keeps escaping me. I've finally gotten some "movement" on page load.. but to tell you the truth, I can't figure out if it's my html structure, css styles, or implementation of serialScroll causing the issue. here's the code for the buttons: <ul id="portfolioNav"> <li><a href="" id="prev">&larr;</a></li> <li><a href="" id="next">&rarr;</a></li> </ul> Here's the script, as it is right now: $('#mainContent').css('overflow', 'hidden'); $('#mainContent').serialScroll({ items:'.portfolioItem', prev:'a#prev', next:'a#next', axis: 'x', duration:1200, force:true, stop:true, lock:false, easing:'easeOutQuart', jump: true });

  • CSS Caching and User-CUstomized CSS - Any Suggestions?

    - by Joe
    I'm just trying to figure out the best approach here... my consideration is that I'd like my users to be able to customize the colors of certain elements on the page. These are not pre-made css they can choose from, but rather styles that can be edited using javascript to change the style, so they cannot be "pre-made" into separate style sheets. I am also generating the css into a cache directory since I am generating the css through a PHP script. I am thinking that, perhaps I should: 1) If cached css file doesn't exist, create css file using the website default style settings. 2) If cached css file does exist, check if user has custom settings, if so, edit the cache file before displaying it. Btw, when I refer to "cached file" I mean the PHP generated css document. My goal is to prevent the need to have PHP re-generate the css file each time, whilst still allowing users, when logged in, to have their customized css settings applied. I will store these settings in a database most likely so when they return it is saved for them when they login.

  • Proggraming a VPN, Authontication stage - RFC not clear enough

    - by John
    I have a custom build of a unix OS. My task: Adding an IPSec to the OS. I am working on Phase I, done sending the first 2 packets. what I am trying to do now is making the Identefication Payload. I've been reading RFC 2409 (Apendix B) which discuss the keying materials (SKEYID, SKEYID_d, SKEYID_a, SKEYID_e and the IV making). Now, I use SHA1 for authontication and thus I use HMAC-SHA1 & my encryption algorithem is AES 256bit. The real problem is that the RFC is not clear enough of what should I do regarding the PRF. It says: "Use of negotiated PRFs may require the PRF output to be expanded due to the PRF feedback mechanism employed by this document." I use SHA1, does it mean I do not negotiate a PRF? In my opinion, AES is the only algorithm that needs expention (a fixed length of 256bit), so, do i need to expand only the SKEYID_e? If you happen to know a clearer, though relible, source then the RFC please post a link. Thanks in advance!

  • C++ Formatting like visual studio c# formatting

    - by Fire-Dragon-DoL
    I like the way Visual studio (2008) format C# code; unfortunately it seems it doesn't behave in the same way when writing C++ code. For example, when I write a code in this way: class Test { public: int x; Test() {this->x=20;} ~Test(){} }; in C# (ok this is C++ but you can understand what I mean), this part: Test() {this->x=20;} Will become Test() { this->x=20; } This is obviusly a stupid example, but there are a lot of things where putting brackets in correct position, indenting code and other things with my own hands becomes boring. I can obviusly change editor if you suggest me a good one for C++ code, I would like to find something with these features: Intellisense (like vs, at least similiar) Custom class coloring (in c# they are cyan, why are they black in c++?) Wordwrap (possibly) Documentation when you mouse over a method/variable Auto formatting (when you close a bracket like "}" in c# you'll get everything well formatted) obviusly I can find other features, but this is what is in my mind at the moment. Thanks for any suggestion

  • How could I make this display for listbox?

    - by baron
    Hello everyone, I have a databound listbox which is actually displaying two columns of data. It is displayed as follows: <UserControl.Resources> <DataTemplate x:Key="AlignedPairs"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="10" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding Fruits}" Grid.Column="0" /> <TextBlock Text="->" TextAlignment="Center" Grid.Column="1" /> <TextBlock Text="{Binding Colors}" Grid.Column="3" /> </Grid> </DataTemplate> </UserControl.Resources> <ListBox Name="lbStuff" Grid.ColumnSpan="2" Grid.Row="1" ItemTemplate="{StaticResource AlignedPairs}"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch" /> </Style> </ListBox.ItemContainerStyle> </ListBox> Then Itemsource set in codebehind. Based on some logic however, I would like to set either a line or a item in one of the columns, e.g. a fruit to red, or the line to bold. I have code to work out which Fruit or Color I would like to differentiate (by color/bold) in the code behind, but I can't figure out, especially given the custom listbox display, how I could go about setting a particular item to a different color/bold. Does anyone have any ideas? Let me know if any further code is required. Cheers.

  • Understanding Flash SWC's imported into Flex Builder 3 and key framed animation

    - by Hank Scorpio
    I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar). The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this : removeChild(myPreloader); myPreloader = null; though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation. Any clues to this would be greatly appreciated.

  • Rendering a control generates security exception in .Net 4

    - by Jason Short
    I am having a problem with code that worked fine in .Net 2 giving this error under .Net 4. Build (web): Inheritance security rules violated while overriding member: 'Controls.RelatedPosts.RenderControl(System.Web.UI.HtmlTextWriter)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden. This is in DotNetBlogEngine. There were several other security demands in the code that .Net 4 didn't seem to like. I followed some of the advice I found on blogs (and here) and got rid of all the other errors. But this one still eludes me. The Main blogengine core dll is not set for security demands anylonger and is compiled for .Net 4 as well. This error is in the website side attempting to use the dll. There are controls that call a RenderControl method taking an HtmlTextWriter. Apparently the text writer now has some soft of security attributes set on it. Each of the controls implements a custom interface ( public interface ICustomFilter ), there are no security permissions present or demands. The site is running full trust on my local dev machine.

  • cellForRowAtIndexPath: crashes when trying to access the indexPath.row/[indexPath row]

    - by Emil
    Hey. I am loading in data to a UITableView, from a custom UITableViewCell (own class and nib). It works great, until I try to access the indexPath.row/[indexPath.row]. I'll post my code first, it will probably be easier for you to understand what I mean then. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CustomCell"; CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id currentObject in topLevelObjects){ if ([currentObject isKindOfClass:[CustomCell class]]){ cell = (CustomCell *) currentObject; break; } } } NSLog(@"%@", indexPath.row); // Configure the cell... NSUInteger row = indexPath.row; cell.titleLabel.text = [postsArrayTitle objectAtIndex:indexPath.row]; cell.dateLabel.text = [postsArrayDate objectAtIndex:indexPath.row]; cell.cellImage.image = [UIImage imageWithContentsOfFile:[postsArrayImg objectAtIndex:indexPath.row]]; NSLog(@"%@", indexPath.row); return cell; } The odd thing is, it does work when it loads in the first three cells (they are 125px high), but crashes when I try to scroll down. The indexPath is always avaliable, but not the indexPath.row, and I have no idea why it isn't! Please help me.. Thanks.

  • Issues in Convergence of Sequential minimal optimization for SVM

    - by Amol Joshi
    I have been working on Support Vector Machine for about 2 months now. I have coded SVM myself and for the optimization problem of SVM, I have used Sequential Minimal Optimization(SMO) by Mr. John Platt. Right now I am in the phase where I am going to grid search to find optimal C value for my dataset. ( Please find details of my project application and dataset details here http://stackoverflow.com/questions/2284059/svm-classification-minimum-number-of-input-sets-for-each-class) I have successfully checked my custom implemented SVM`s accuracy for C values ranging from 2^0 to 2^6. But now I am having some issues regarding the convergence of the SMO for C 128. Like I have tried to find the alpha values for C=128 and it is taking long time before it actually converges and successfully gives alpha values. Time taken for the SMO to converge is about 5 hours for C=100. This huge I think ( because SMO is supposed to be fast. ) though I`m getting good accuracy? I am screwed right not because I can not test the accuracy for higher values of C. I am actually displaying number of alphas changed in every pass of SMO and getting 10, 13, 8... alphas changing continuously. The KKT conditions assures convergence so what is so weird happening here? Please note that my implementation is working fine for C<=100 with good accuracy though the execution time is long. Please give me inputs on this issue. Thank You and Cheers.

  • Best full text search for mysql?

    - by ConroyP
    We're currently running MySQL on a LAMP stack and have been looking at implementing a more thorough, full-text search on our site. We've looked at MySQL's own freetext search, but it doesn't seem to cope well with large databases, which makes it far too slow for our needs. Our main requirements are: speed returning results simple updating of index In addition to the above, our "nice to have"s are: ideally not something that requires adding a module to MySQL plays nicely with PHP (majority of our dev work done using PHP) There seems to be quite a few healthy open-source projects to add fast, reliable full-text search to MySQL, so I'm basically looking for recommendations/suggestions on what you've found to be the most useful product out there, easiest to set up, etc. So far, the list of ones we've been starting to play around with are: Sphinx, C++ based, used by craigslist, thepiratebay Lucene, Java-based Apache project, powers zeoh.com and zoomf.com Solr, Java-based offshoot of Lucene, used to power searches on Digg, CNet & AOL Channels Are there any better ones out there that we haven't come across yet? Can you recommend / suggest against any of the options we've gathered so far? Thanks for your help! Update @Cletus suggested Google's Custom Search Engine. We recently trialled this on a couple of projects, and it's an almost-perfect fit for our needs. The problem is that entries on our site are updated quite regularly, and unfortunately the speed at which entries go in/get updated in Google's index was just too slow and erratic for us to rely on, even with the addition of sitemaps and requested crawl rate changes.

  • CATiledLayer blanking tiles before drawing contents

    - by Greg Plesur
    All, I'm having trouble getting behavior that I want from CATiledLayer. Is there a way that I can trigger the tiles to redraw without having the side-effect that their areas are cleared to white first? I've already subclassed CATiledLayer to set fadeDuration to return 0. To be more specific, here are the details of what I'm seeing and what I'm trying to achieve: I have a UIScrollView with a big content size...~12000x800. Its content view is a UIView backed by a CATiledLayer. The UIView is rendered with a lot of custom-drawn lines Everything works fine, but the contents of the UIView sometimes change. When that happens, I'd like to redraw the tiles as seamlessly as possible. When I use setNeedsDisplay on the view, the tiles redraw but they are first cleared to white and there's a fraction-of-a-second delay before the new content is drawn. I've already subclassed CATiledLayer so that fadeDuration is set to 0. The behavior that I want seems like it should be possible...when you zoom in on the scrollview and the content gets redrawn at a higher resolution, there's no blanking before the redraw; the new content is drawn right on top of the old one. That's what I'm looking for. Thanks; I appreciate your ideas. Update: Just to follow up - I realized that the tiles weren't being cleared to white before the redraw, they're being taken out entirely; the white that I was seeing is the color of the view that's beneath my CATiledLayer-backed view. As a quick hack/fix, I put a UIImageView beneath the UIScrollView, and before triggering a redraw of the CATiledLayer-backed view I render its visible section into the UIImageView and let it show. This smooths out the redraw significantly. If anyone has a better solution, like keeping the redraw-targeted tiles from going away before being redrawn in the first place, I'd still love to hear it.

  • WordPress > Optimizing a query to show recent posts with a "View All" link when postcount exceeds ma

    - by Scott B
    I have a setting in my theme that allows the site owner to set the maximum number of posts ($maxPosts) to display in a "Recent Posts" menu. I'm using a custom script to generate the recent posts (because the Recent Posts widget does not highlight the current page, which I need for my css). My menu also is set up to display a "View All" link below the post listing, but only if the actual post count is $maxposts I'm trying to work out the best method for getting the post count and comparing it to $maxposts in order to determine whether or not to show a "View All" link. I'm sure there's probably a better way, but here's my code. I'm looking to optimize it to support very large post counts... $cat=get_cat_ID('excludeFromRecentPosts'); $catHidden=get_cat_ID('hidden'); $myquery = new WP_Query(); $myquery->query(array( 'cat' => "-$cat,-$catHidden", 'post_not_in' => get_option('sticky_posts') )); $myrecentpostscount = $myquery->found_posts; if ($myrecentpostscount > 0) { //show the menu if ($myrecentpostscount > $maxPosts) { //show "View All" link } } I really only need to determine if the total post count from the query is greater than the maxPost setting in order to determine whether to show the "View All" link, so I'm wondering if, in the case there are thousands of posts matching the criteria, to avoid performance issues, I don't need to get a count of all of them. I just need to count up until the point of maxPosts + 1, and that's where I'm struggling a bit because the user could elect to make maxPosts = -1 which means they want to show all posts. But this would be impractical, so I would probably set a upper limit of 20...

  • IE7 issue - cannot download streamed file when Automatic prompting for file downloads is disabled

    - by Jai ganesh K
    Hi, My application is J2EE (JSP/Servlet) based. I encounter an issue when i try to open a new window (pop-up) from JSP and call a Servlet action (e.g. Streamer.do) which streams a PDF file inside that pop-up. Problem: While IE 7 - Tools - Internet Options - Security - Custom Level - Downloads - Automatic prompting for file downloads is Disabled and while pop-up window get opened, I am unable to download the file (Save/Open prompt is not comming up). In contrast, when I enable this option, I am able to download. But this option sometimes would be disabled in some environments. While testing this in Mozilla Firefox 3.0/3/5/IE6 it is working fine without any settings change. When i check it to enable i then get the Save/Open prompt to work correctly. This should be problem with IE7. Can anybody help us with Javascript or any working settings which doesnt care whether the "Automatic prompting for downloads" option in IE7 is enabled. Any help in this would be much appreciated. Regards! Jai

  • Implementing a customized drawable in Android

    Hi , I was trying to get hold of 2D graphics in Android. As a example i want to implement a custom drawable and show it in my Activity I have defined a customized drawable by extending from Android drawable as mentioned below myDrawable extends Drawable { private static final String TAG = myDrawable.class.getSimpleName(); private ColorFilter cf; @Override public void draw(Canvas canvas) { //First you define a colour for the outline of your rectangle Paint rectanglePaint = new Paint(); rectanglePaint.setARGB(255, 255, 0, 0); rectanglePaint.setStrokeWidth(2); rectanglePaint.setStyle(Style.FILL); //Then create yourself a Rectangle RectF rectangle = new RectF(15.0f, 50.0f, 55.0f, 75.0f); //in pixels Log.d(TAG,"On Draw method"); // TODO Auto-generated method stub Paint paintHandl = new Paint(); // paintHandl.setColor(0xaabbcc); paintHandl.setARGB(125, 234, 213, 34 ); RectF rectObj = new RectF(5,5,25,25); canvas.drawRoundRect(rectangle, 0.5f, 0.5f, rectanglePaint); } @Override public int getOpacity() { // TODO Auto-generated method stub return 100; } @Override public void setAlpha(int alpha) { // TODO Auto-generated method stub } @Override public void setColorFilter(ColorFilter cf) { // TODO Auto-generated method stub this.cf = cf; } } I am trying to get this displayed in my activity, as shown below public class custDrawable extends Activity { /** Called when the activity is first created. */ LinearLayout layObj = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); layObj = (LinearLayout) findViewById(R.id.parentLay); ImageView imageView = (ImageView) findViewById(R.id.icon2); myDrawable myDrawObj = new myDrawable(); imageView.setImageDrawable(myDrawObj); imageView.invalidate(); // layObj.addView(myDrawObj, params); } } But when i run the app i see no rectangle on the activity, can anyone help me out?

  • C++ resize a docked Qt QDockWidget programmatically?

    - by Zac
    I've just started working on a new C++/Qt project. It's going to be an MDI-based IDE with docked widgets for things like the file tree, object browser, compiler output, etc. One thing is bugging me so far though: I can't figure out how to programmatically make a QDockWidget smaller. For example, this snippet creates my bottom dock window, "Build Information": m_compilerOutput = new QTextEdit; m_compilerOutput->setReadOnly(true); dock = new QDockWidget(tr("Build Information"), this); dock->setWidget(m_compilerOutput); addDockWidget(Qt::BottomDockWidgetArea, dock); When launched, my program looks like this: http://yfrog.com/6ldreamidep (bear in mind the early stage of development) However, I want it to appear like this: http://yfrog.com/20dreamide2p I can't seem to get this to happen. The Qt Reference on QDockWidget says this: Custom size hints, minimum and maximum sizes and size policies should be implemented in the child widget. QDockWidget will respect them, adjusting its own constraints to include the frame and title. Size constraints should not be set on the QDockWidget itself, because they change depending on whether it is docked Now, this suggests that one method of going about doing this would be to sub-class QTextEdit and override the sizeHint() method. However, I would prefer not to do this just for that purpose, nor have I tried it to find that to be a working solution. I have tried calling dock-resize(m_compilerOutput-width(), m_compilerOutput-minimumHeight()), calling m_compilerOutput-setSizePolicy() with each of its options...nothing so far has affected the size. Like I said, I would prefer a simple solution in a few lines of code to having to create a sub-class just to change sizeHint(). All suggestions are appreciated.

  • Creating instance of a service-side DataContract class on client-side in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

  • How to set up a user Quartz2D coordinate system with scaling that avoids fuzzy drawing?

    - by jdmuys
    This topic has been scratched once or twice, but I am still puzzled. And Google was not friendly either. Since Quartz allows for arbitrary coordinate systems using affine transform, I want to be able to draw things such as floorplans using real-life coordinate, e.g. feet. So basically, for the sake of an example, I want to scale the view so that when I draw a 10x10 rectangle (think a 1-inch box for example), I get a 60x60 pixels rectangle. It works, except the rectangle I get is quite fuzzy. Another question here got an answer that explains why. However, I'm not sure I understood that reason why, and moreover, I don't know how to fix it. Here is my code: I set my coordinate system in my awakeFromNib custom view method: - (void) awakeFromNib { CGAffineTransform scale = CGAffineTransformMakeScale(6.0, 6.0); self.transform = scale; } And here is my draw routine: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect r = CGRectMake(10., 10., 11., 11.); CGFloat lineWidth = 1.0; CGContextStrokeRectWithWidth(context, r, lineWidth); } The square I get is scaled just fine, but totally fuzzy. Playing with lineWidth doesn't help: when lineWidth is set smaller, it gets lighter, but not crisper. So is there a way to set up a view to have a scaled coordinate system, so that I can use my domain coordinates? Or should I go back and implementing scaling in my drawing routines? Note that this issue doesn't occur for translation or rotation. Thanks

  • Windows-Mobile Directshow: Specifying bitrate/quality of a WMV video capture

    - by Landstander
    Hi- I'm stumped on this, and I'm really hoping someone could point me in the right direction. I'm currently capturing video in Windows Mobile and encoding it using the WMV 9 DMO (CLSID_CWMV9EncMediaObject). That all works well enough, but the output video's bitrate is too high, resulting in a video file that's much too large for my needs. Ultimately, my goal is to mimic the video settings that Microsoft's Camera Capture Dialog outputs in the "messaging" quality mode (64kbps) from my C++ code. Currently, my code's outputting a WMV file with a bitrate of 352kbps. The only example I could find of specifying the capture bitrate with a WMV9 DMO was this. The idea in that code was basically to use a propertybag to write a bitrate to a property of the DMO. Update: In windows mobile, the closest codec property I can find that seems to equate to the bitrate is "g_wszWMVCVBRQuality". Microsoft's documentation of this property is extremely confusing to me: It basically seems to say that a higher number equates to a higher quality, but it gives absolutely no explanation of the specifics for each number. When I attempt to set this property to value like "1" via a propertybag for the WMV9 DMO, I run into a -2147467259 (unknown) error. To summarize: What is the basic strategy to specify the bitrate/quality of a video being captured via directshow (wmv9) on a windows mobile platform? I've heard (or wondered about) the following methods: Use the propertybag to change the encoder DMO's property that corresponds to bitrate/quality (currently failing) Create your own custom transcoder/encoder to specify it. This seems unnecessary since the WMV encoder works well enough- it's just at too high a bitrate. The VIDEOINFOHEADER has a bitrate property, but I suspect that specifying new settings here will do nothing to alter the actual encoding process since I wouldn't think file attributes would come into play until after the encoding. Any suggestions? PS: I would post specific source code, but at this point it may confuse more than it helps since I'm floundering so much on how to do this. At this point, I'm just trying to validate the general strategy. THANKS!

  • In JQGrid I want to add a row button that doesnt post back.

    - by snyder
    The buttons I have added to the rows still post back even if I specifiy not to do so in the onclick method of the button (onclick=' return false;'). I supose its the grid doing the post back? I am tring to prevent the postback and show my own custom popup forms. gridComplete: function(){ var ids = $('#jqGridControl1').jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var rowid = ids[i]; de = "<input type='image' title='Delete this record.' src='../images/icn_delete.gif' onclick=' return false;' style='border-width:0px;'/>"; ee = "<input type='image' title='Edit this record.' src='../images/icn_edit.gif' onclick=' return false;' style='border-width:0px;' />"; ve = "<input type='image' title='View related information.' src='../images/house.gif' onclick='return false;' style='border-width:0px;' />"; pe = "<input type='image' title='Print' src='../images/icn_printer.gif' onclick=' return false;' style='border-width:0px;' />"; je = "<input type='image' title='Appointment' src='../images/icn_journal.gif' onclick=' return false;' style='border-width:0px;' />"; se = "<input type='image' title='Select' src='../images/icn_select.gif' onclick=' return false;' style='border-width:0px;' />"; jQuery('#jqGridControl1').jqGrid('setRowData',ids[i],{act:de+ee+ve+pe+je+se}); }

  • Drupal CCK field type with complex fAPI child fields

    - by Cliff Smith
    This question is basically a follow-up to this one: http://stackoverflow.com/questions/1640534/drupal-custom-cck-field-with-multiple-child-fields I need to build a CCK field type that stores several pieces of data, and fAPI form elements to accept the input for each piece of data already exist. These elements are built out into multiple HTML form inputs with fAPI #process functions. The problem is that when I try to use these elements in my CCK field, the input from the widget doesn't line up with the database columns specified in hook_field_settings(). The widget returns something like this: Array ( [thumbnail_image] => [imceimage_path] => ... [imceimage_alt] => ... [imceimage_width] => ... [imceimage_height] => ... [user_address] => [address_number] => ... [address_street] => ... [address_city] => ... [address_state] => ... Unless there's a way to specify "sub-columns" in hook_field_settings(), it appears to me that I can't use form element types with sub-elements in CCK fields. I've tried using CCK field validation to pull out the "imce_xxx" values from thumbnail_image and likewise with user_address, but that doesn't get me anywhere. Is it not possible to use form elements with child elements in CCK field definitions? Thanks, Cliff Smith

  • JSF 2.0: Validate equality of 2 InputSecret Fields (confirm password) without writing Code?

    - by yournamehere
    I'm developing a pure JavaEE6 application with JSF 2.0 and Glassfish. My JSF implementation is Primefaces (beside Mojarra provided by Glassfish). I want to verify if the values of 2 password fields in a JSF form are equal. With Seam, there is the neat component <s:validateEquality for="pw1"/>. I want do to the same without Seam, just using JSF (or maybe a component of a JSF library). Until now i only saw examples which validate the form with a custom validator. But i would like to compare the fields without writing Java code or Javascript code. Is that possible? This what it looks like with Seam: ... <h:inputSecret id="passwort" value="#{personHome.instance.password}" redisplay="true" required="true"> <f:validateLength minimum="8"/> <a:support event="onblur" reRender="passwortField" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... <h:inputSecret id="passwort2" required="true" redisplay="true"> <!-- find the JSF2.0-equivalent to this tag: --> <s:validateEquality for="passwort"/> <a:support event="onblur" reRender="passwort2Field" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... Any help is appreciated. Thanks!

  • 2-step user registration with Django

    - by David S
    I'm creating a website with Django and want a fairly common 2-step user registration. What I mean by this is that the user fills in the some basic user information + some application specific information (sort of like a coupon value). Upon submit, an email is sent to ensure email address is valid. This email should contain a link to click on to "finish" the registration. When the link is clicked, the user is marked as validated and they are directed to a new page to complete optional "user profile" type information. So, pretty basic stuff. I have done some research and found django-registration by James Bennett. I do know who James is and have seen him at PyCons and DjanoCons in the past. There is obviously very few people in the world that know Django better than James (so, I know the quality of the code/app is good). But, it almost seems like a bit of over kill. I've read through the docs and was a bit confused (maybe I'm just being a bit dense today). I believe that if I do use django-registration, I will need to have some custom forms, etc. Is there anything else out there I should evaluate? Or are there any good tutorials or videos on using django-registration? I've done a bit of googling, but haven't found anything. But, I suspect that it might be a case of a lot of very common words that don't really find what you are looking for (django user registration tutorial/example). Or is just a case where it would be just about as easy to build your own solution with Django forms, etc? Here is the tech stack I'm using: Python 2.7.2 Django 1.3.1 PostgreSQL 9.1 psycopg2 2.4.1 Twitter Bootstrap 2.0.2

  • Inheritance using prototype / "new"

    - by mikkol
    Hi I'm new in Javascript OO and want to know more about about inheritance. Hope you can provide some advice! I see this great post: How to "properly" create a custom object in JavaScript? which talks about how a class is inherited as I see in other websites, ex.: function man(x) { this.x = x; this.y = 2; } man.prototype.name = "man"; man.prototype.two = function() { this.y = "two"; } function shawn() { man.apply(this, arguments); }; shawn.prototype = new man; The above post claims that in order not to call "man"'s constructor while inheriting, one can use a helper like this instead: function subclassOf(base) { _subclassOf.prototype= base.prototype; return new _subclassOf(); } function _subclassOf() {}; shawn.prototype = subclassOf(man); While I understand its intention, I don't see why we can't call shawn.prototype = man.prototype; I see it works exactly the same. Or is there something I'm missing? Thanks in advance!
