• Wordpress/CSS: List Style Problem.

  - by Ben

  Hi all! I am reasonably new to Wordpress custom themes but I do have some knowlege of CSS, although I am terrible at customising other peoples code which is why I have the problem I am about to explain. I have started a website that my girlfriend and I are doing together. It uses the Simplo Wordpress theme which is pretty cool but when you add a post that has a list in it. It doesn't show the bullets on each of the items. I have tried adding 'list-style:circle;' to a the.postItem class and a couple of other divs and classes that I thought were relevant but it doesn't work. You can take a look for yourself, it may be easier to understand my problem that way. If you go to: http://brokeandstarving.com/234/bennos-shepherds-pie/ there is a list of ingredients and also the steps under the method is a list as well. My question is, where do I edit the CSS to make the bullets appear next to the list items? I hope that makes sense. Thanks in advance, - Ben

• ASP.Net forms authentication - multiple providers

  - by Chris Klepeis

  I have an ASP.Net 4.0 application, and within it is a folder called "Forum", setup as a sub application in IIS 7. This forum package implements a custom provider for .net membership. The forum is running in .net 3.5. I'd like to setup the main site so that when users login, it logs them into both my site and the forum site. Both the main site and the forum have separate .Net membership tables. How can I specify which provider to use with formsauthentication? right now I have FormsAuthentication.SetAuthCookie(...); this, however, just uses my default provider and does nothing with the provider for the forum I tried setting the forum app and my web app to have the same cookie name, as well as setting the machinekey on each: <machineKey validationKey="AutoGenerate" validation="SHA1" /> no dice. I googled and didnt really come up with any example of how to use multiple providers like I want to. I updated my web.config to have both provideers but this is useless if I cannot specify in my code which one to use.

• UITableView UITableViewCell dynamic UILabel Height storyboard

  - by Mikel Nelson

  This isn'an a question, just a results log on an issue I had with XCode 4.5 storyboards and dynamic height UITableCell with a UILabel. The issue was; the initial display of a cell would only show part of the resized UILabel contents, and that the visual UILabel was not resized. It would only display correctly after scrolling off the top of the Table and back down. I did the calculations in hieghtForRowAtIndexPath and sizeToFit the UILabel in rowAtIndexPath. The sizes where coming up ok in debug, but the device was not updating the display with the correct size and UILable.text value. I had created the dynamic UITableCell in a storyboard. However, I had set the width and height to a nominal value (290x44). It turns out, this was causing my issues. I set the width and height to zero (0) in the story board, and everything started working correctly. (i.e. the UILabels displayed at the correct size with full content). I was unable to find anything online on this issue, except for some references to creating the custom table cell with a frame of zero. Turns out, that was really the answer (for me).

Thanks in advance -rockdale

• jQuery rotator not rotating properly - too much recursion

  - by Matt Nathanson

  I've built a custom jQuery rotator using just basic animation to rotate the 3 Divs (images). I've built the function and then reinitiate the function using it as a call back. Here's the code: function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber-1; if ( featureNumber == 1) {featureNumber2=3} var CurrentFeature2 = "#container" + featureNumber2; $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); $('#container2').stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); var featureNumber3 = featureNumber+1; if ( featureNumber == 3){featureNumber3=1} var CurrentFeature3 = "#container" + featureNumber3; $(CurrentFeature3).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); if (featureNumber ==1) {featureNumber=3} else{featureNumber--}; $(CurrentFeature).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature3).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature2).stop(false, false).delay(4500).animate({'top' : '-330px'}, 25,ImageRotate()); }; It's worth noting that when calling the function again I also tried making another function called ImageRotate2(); and it did the same thing. It loops, but i get all sorts of funkiness. Edit: I've also tried some answers in the replies and they both leave me with recursion errors each second.

• FluentNHibernate mapping of composite foreign keys

  - by Faron

  I have an existing database schema and wish to replace the custom data access code with Fluent.NHibernate. The database schema cannot be changed since it already exists in a shipping product. And it is preferable if the domain objects did not change or only changed minimally. I am having trouble mapping one unusual schema construct illustrated with the following table structure: CREATE TABLE [Container] ( [ContainerId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_Container] PRIMARY KEY ( [ContainerId] ASC ) ) CREATE TABLE [Item] ( [ItemId] [uniqueidentifier] NOT NULL, [ContainerId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_Item] PRIMARY KEY ( [ContainerId] ASC, [ItemId] ASC ) ) CREATE TABLE [Property] ( [ContainerId] [uniqueidentifier] NOT NULL, [PropertyId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_Property] PRIMARY KEY ( [ContainerId] ASC, [PropertyId] ASC ) ) CREATE TABLE [Item_Property] ( [ContainerId] [uniqueidentifier] NOT NULL, [ItemId] [uniqueidentifier] NOT NULL, [PropertyId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_Item_Property] PRIMARY KEY ( [ContainerId] ASC, [ItemId] ASC, [PropertyId] ASC ) ) CREATE TABLE [Container_Property] ( [ContainerId] [uniqueidentifier] NOT NULL, [PropertyId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_Container_Property] PRIMARY KEY ( [ContainerId] ASC, [PropertyId] ASC ) ) The existing domain model has the following class structure: The Property class contains other members representing the property's name and value. The ContainerProperty and ItemProperty classes have no additional members. They exist only to identify the owner of the Property. The Container and Item classes have methods that return collections of ContainerProperty and ItemProperty respectively. Additionally, the Container class has a method that returns a collection of all of the Property objects in the object graph. My best guess is that this was either a convenience method or a legacy method that was never removed. The business logic mainly works with Item (as the aggregate root) and only works with a Container when adding or removing Items. I have tried several techniques for mapping this but none work so I won't include them here unless someone asks for them. How would you map this?

• MKMapKit exception when using canShowCallout on annotation view

  - by Kendall Helmstetter Gelner

  I'm trying to use a pretty straightforward custom map annotation view and callout - the annotation view when I create it, just adds a UIImageView as a subview to itself. That works fine. However, when I call canShowCallout on the annotation view, An exception is thrown in MapKit immediately after returning the view. The end of the stack looks like: #0 0x94e964e6 in objc_exception_throw #1 0x01e26404 in -[MKOverlayView _addViewForAnnotation:] #2 0x01e22037 in -[MKOverlayView _addViewsForAnnotations:animated:] #3 0x01e1ddf9 in -[MKOverlayView showAddedAnnotationsAnimated:] #4 0x01df9c0e in -[MKMapView _showAddedAnnotationsAndRouteAnimated:] #5 0x01e0371a in -[MKMapView levelView:didLoadTile:] My viewForAnnotation is pretty simple: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { if ( ! [annotation isKindOfClass:[MyAnnotation class]] ) return nil; MyAnnotationView *useView = (MyAnnotationView *)[myMapView dequeueReusableAnnotationViewWithIdentifier:@"resuseview"]; if ( useView == nil ) { useView = [[[MyAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"resuseview"] autorelease]; useView.canShowCallout = YES; // if commented out view appears just fine } else { useView.annotation = annotation; } return useView; } As noted in the code, the annotation view works fine as is - until I add canShowCallout, then it crashes the first time the map gets the view.

• ActionScript : Applying frame to a image / background?

  - by Jay

  I am editing a custom calendar application in flash. The purpose of this app is to let you select your own images, and create a calendar out of it. You can basically, drag and drop images of your choice and they apply frame/borders, or drag and drop embellishments. Here is the piece of code that draws a border/frame on the embellishment/image of your choice. tempListener.onLoadInit = function(target_mc:MovieClip) { var mcName = target_mc._name.substring(0, target_mc._name.indexOf("@", 0)); if(mcName == "frame_Image") { target_mc.onPress = function() { if(_root.selectedImage != null) { var index = this._name.substring(this._name.indexOf("@",0)+1, this._name.length); var objPath = nodesFrames.childNodes[index-1].attributes.image; if(_root.selectedImage._name.split("@")[0] == "image") { var mask = _root.selectedImage[_root.selectedImage._parent._name + "_" + _root.selectedImage._name + "_maskMc"]; frameImageWidth = mask._width; frameImageHeight = mask._height; frameImageXScale = -1; frameImageYScale = -1; } else { frameImageXScale = _root.selectedImage._xscale; frameImageYScale = _root.selectedImage._yscale; _root.selectedImage._xscale = 100; _root.selectedImage._yscale = 100; frameImageWidth = _root.selectedImage._width; frameImageHeight = _root.selectedImage._height; } if(_root.selectedImage["frame"]) {} else { _root.selectedImage.createEmptyMovieClip("frame", _root.selectedImage.getNextHighestDepth()); } var image_mcl1:MovieClipLoader = new MovieClipLoader(); image_mcl1.addListener(_root.mclFrameListener); image_mcl1.loadClip("Images/" + objPath, _root.selectedImage["frame"]); } } } I need to somehow apply the chosen frame image, to the entire background - not just to the embellishment or image. How do I go about this? Thanks in advance for your inputs. Please let me know if the question doesn't make sense, I will attach some images that can help you with the context.

• How do I flatten an associative array into an array with only values in PHP?

  - by aalaap

  I have an array that has keys and values. For eg: Array ( [name] => aalaap [age] => 29 [location] => mumbai ) I want to convert the keys from this into values, but I want the values to apear right after the keys. For eg: Array ( [0] => name [1] => aalaap [2] => age [3] => 29 [4] => location [5] => mumbai ) I can easily write an iteration function that will do this... for eg: array_flatten($arr) { foreach ($arr as $arrkey => $arrval) { $arr_new[] = $arrkey; $arr_new[] = $arrval; } return $arr_new; } ...but I'm trying to find out if there's any way this can be accomplished using array_combine, array_keys, array_values and/or array_merge, preferably in one, so i don't need to use a custom function. Is there?

• Google Maps InfoBubble pixelOffset

  - by Sam

  I am trying to implement a custom infoBubble that has the box opening to the side of a marker. This has turned out to be harder than expected. Using the normal infoWindow you can use pixelOffset. See here for the documentation Using infoBubble this does not seem to be the case. Is there anyway of using pixelOffset in an infoBubble, or something that will do the same thing? I have found this very difficult to search for, as using a google search such as this returns no relevant results Google Search Below is all my resources I have been using. Example of infoBubble here. My JavaScript to setup the map and infoBubble here. And now my javascript here just in-case the jsfiddle link is broken. <script type="text/javascript"> $(document).ready(function () { init(); }); function init() { //Setup the map var googleMapOptions = { center: new google.maps.LatLng(53.5167, -1.1333), zoom: 13, mapTypeId: google.maps.MapTypeId.ROADMAP }; //Start the map var map = new google.maps.Map(document.getElementById("map_canvas"), googleMapOptions); var marker = new google.maps.Marker({ position: new google.maps.LatLng(53.5267, -1.1333), title: "Just a test" }); marker.setMap(map); infoBubble = new InfoBubble({ map: map, content: '<div class="phoneytext">Some label</div>', //position: new google.maps.LatLng(-35, 151), shadowStyle: 1, padding: '10px', //backgroundColor: 'rgb(57,57,57)', borderRadius: 5, minWidth: 200, arrowSize: 10, borderWidth: 1, borderColor: '#2c2c2c', disableAutoPan: true, hideCloseButton: false, arrowPosition: 7, backgroundClassName: 'phoney', pixelOffset: new google.maps.Size(130, 120), arrowStyle: 2 }); infoBubble.open(map, marker); } </script>

• What can I read from the iPad Camera Connection Kit?

  - by HELVETICADE

  I'm building a small controller device that I'd like to partner with a computer. I've settled on using OSC out from my custom built hardware and am pretty satisfied with what I can get from WOscLib. Two goals I'd like to achieve are portability and a very ratio between battery:computing power, and this has lured me towards using iPhoneOS to accomplish my goals. I think the iPad would suit my needs perfectly, except that using wifi to broadcast OSC out from my device requires a third device and would destroy the goal of portability, whilst also introducing potential latency and stability headaches. My question is pretty simple: Can I push my OSC-out FROM my controller TO an iPad via USB and the Camera Connection Kit? If I could accomplish this, the two major goals of my project would be fulfilled very nicely. This seems like it should be a simple little question, but researching this obsessively over the past few weeks has left me more almost more uncertain than if I had done no research at all. I'd really like some more confidence before I go down this route, and it seems like it should be possible. Any insight would be very, very appreciated.

• WCF throttling and emptying the listenBacklog quickly

  - by user1161625

  I'm sort of a WCF newbie (inheriting tasks from someone) and I'm trying to better throttle my application. We have a service that sends print jobs to the Windows print queue and it seems that rather than dumping all of the jobs into the queue it holds on to them in the listenBacklog and slowly releases them to the Windows print queue. Here is my throttling behavior: <behavior name="throttling"> <serviceThrottling maxConcurrentCalls="144" maxConcurrentSessions="1168" /> <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/> </behavior> I'm using a custom binding for this service also which is here: <customBinding> <binding name="oneWayPrintBinding" receiveTimeout="00:30:00"> <reliableSession maxPendingChannels="16" inactivityTimeout="01:30:00" /> <binaryMessageEncoding> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" /> </binaryMessageEncoding> <tcpTransport maxReceivedMessageSize="67108864" listenBacklog="1024" /> </binding> </customBinding> Any recommendations would be very helpful.

• Is it possible to replace values ina queryset before sending it to your template?

  - by Issy

  Hi Guys, Wondering if it's possible to change a value returned from a queryset before sending it off to the template. Say for example you have a bunch of records Date | Time | Description 10/05/2010 | 13:30 | Testing... etc... However, based on the day of the week the time may change. However this is static. For example on a monday the time is ALWAYS 15:00. Now you could add another table to configure special cases but to me it seems overkill, as this is a rule. How would you replace that value before sending it to the template? I thought about using the new if tags (if day=1), but this is more of business logic rather then presentation. Tested this in a custom template tag def render(self, context): result = self.model._default_manager.filter(from_date__lte=self.now).filter(to_date__gte=self.now) if self.day == 4: result = result.exclude(type__exact=2).order_by('time') else: result = result.order_by('type') result[0].time = '23:23:23' context[self.varname] = result return '' However it still displays the results from the DB, is this some how related to 'lazy' evaluation of templates? Thanks! Update Responding to comments below: It's not stored wrong in the DB, its stored Correctly However there is a small side case where the value needs to change. So for example I have a From Date & To date, my query checks if todays date is between those. Now with this they could setup a from date - to date for an entire year, and the special cases (like mondays as an example) is taken care off. However if you want to store in the DB you would have to capture several more records to cater for the side case. I.e you would be capturing the same information just to cater for that 1 day when the time changes. (And the time always changes on the same day, and is always the same)

• Share Localization

  - by fop6316

  I was able to localize my Alfresco Model (+ constraints lists) by following these rules : http://wiki.alfresco.com/wiki/Data_Dictionary_Guide#Model_Localization But I would like to know if there is something similar for Share ? Do we only have to use the "label-id" attributes without worrying of any convention ? Is it better to use : label.companyName=Company name or something like sop_sopModel.field.sop_companyName.title=Company Name or anything else ? I didn't see any recommandation on the wiki. Here is an example of label-id's I don't know how to format. This is a part of my share-config-custom.xml file. I know this is not really important but I would like to do things properly. <config evaluator="aspect" condition="sop:company"> <forms> <form> <field-visibility> <show id="sop:companyName" /> <show id="sop:companyAddress" /> </field-visibility> <appearance> <set id="sopPanel" appearance="bordered-panel" label-id="???" /> <field id="sop:companyName" label-id="???" set="sopPanel" /> <field id="sop:companyAddress" label-id="???" set="sopPanel" /> </appearance> </form> </forms> </config> Thanks

• GZipStream in an WebHttpResponse producing no data

  - by Pierre 303

  I want to compress my HTTP Responses for client that supports it. Here is the code used to send a standard response: IHttpClientContext context = (IHttpClientContext)sender; IHttpRequest request = e.Request; string responseBody = "This is some random text"; IHttpResponse response = request.CreateResponse(context); using (StreamWriter writer = new StreamWriter(response.Body)) { writer.WriteLine(responseBody); writer.Flush(); response.Send(); } The code above works fine. Now I added gzip support below. When I test it with a browser that supports gzip or a custom method, it returns an empty string. I'm sure I'm missing something simple, but I just can't find it... IHttpClientContext context = (IHttpClientContext)sender; IHttpRequest request = e.Request; string acceptEncoding = request.Headers["Accept-Encoding"]; string responseBody = "This is some random text"; IHttpResponse response = request.CreateResponse(context); if (acceptEncoding != null && acceptEncoding.Contains("gzip")) { byte[] bytes = ASCIIEncoding.ASCII.GetBytes(responseBody); response.AddHeader("Content-Encoding", "gzip"); using (GZipStream writer = new GZipStream(response.Body, CompressionMode.Compress)) { writer.Write(bytes, 0, bytes.Length); writer.Flush(); response.Send(); } } else { using (StreamWriter writer = new StreamWriter(response.Body)) { writer.WriteLine(responseBody); writer.Flush(); response.Send(); } }

• Traversing through an arbitrary dictionary tree structure in C#

  - by Rudism

  I am trying to write a recursive C# function that will operate on generic dictionaries of the form IDictionary<string, T> where T is either another IDictionary<string, T> or a string. My first failed attempt looked something like this: public string HandleDict(IDictionary<string, string> dict){ // handle the leaf-node here } public string HandleDict<T>(IDictionary<string, IDictionary<string, T>> dict){ // loop through children foreach(string key in dict.Keys){ HandleDict(dict[key]); } } I also tried variants of HandleDict<T>(IDictionary<string, T>) where T : IDictionary<string, T> but that also doesn't quite work. I know that what I want to do could be achieved through a custom class as the parameter instead of dictionaries, and that my attempts are conceptually flawed (there's no end to the recursion in the generic function). I would still like to know if there is actually a way to do what I want here using just generic IDictionaries.

• Google Adwords API response parse

  - by Yun Ling

  I am trying to figure out how to parse the Adword API query response without exceptions and one issue that i came across is that sometimes, the data itself contains comma besides the comma between each column. Say i do a query on Adroup, campaign and impression by using <reportDefinition xmlns="https://adwords.google.com/api/adwords/cm/v201209"> <selector> <fields>CampaignName</fields> <fields>AdgroupName</fields> <fields>Impressions</fields> <predicates> <field>Status</field> <operator>IN</operator> <values>ENABLED</values> <values>PAUSED</values> </predicates> </selector> <reportName>Custom Adgroup Performance Report</reportName> <reportType>ADGROUP_PERFORMANCE_REPORT</reportType> <dateRangeType>LAST_7_DAYS</dateRangeType> <downloadFormat>CSV</downloadFormat> </reportDefinition> Since my campaign has comma within the string like below: "Adroup,Campaign,Impressions, Premiun Beer, Beer, Chicago, 1000" where the adgroup is "premium beer" and campaign is "Beer,Chicago". that will cause an issue if we parse this information by using comma. Does anyone know how to solve this problem?

• How can i use a commandlinetool (ie. sox) via subprocess.Popen with mod_wsgi?

  - by marue

  I have a custom django filefield that makes use of sox, a commandline audiotool. This works pretty well as long as i use the django development server. But as soon as i switch to the production server, using apache2 and mod_wsgi, mod_wsgi catches every output to stdout. This makes it impossible to use the commandline tool to evaluate the file, for example use it to check if the uploaded file really is an audio file like this: filetype=subprocess.Popen([sox,'--i','-t','%s'%self.path], shell=False,\ stdout=subprocess.PIPE, stderr=subprocess.PIPE) (filetype,error)=filetype.communicate() if error: raise EnvironmentError((1,'AudioFile error while determining audioformat: %s'%error)) Is there a way to workaround for this? edit the error i get is "missing filename". I am using mod_wsgi 2.5, standard with ubuntu 8.04. edit2 What exactly happens, when i call subprocess.Popen from within django in mod_wsgi? Shouldn't subprocess stdin/stdout be independent from django stdin/stdout? In that case mod_wsgi should not affect programms called via subprocess... I'm really confused right now, because the file i am trying to access is a temporary file, created via a filenamevariable that i pass to the file creation and the subprocess command. That file is being written to /tmp, where the rights are 777, so it can't be a rights issue. And the error message is not "file does not exist", but "missing filename", which suggests i am not passing a filename as parameter to the commandlinetool.

  I have a custom UIImageView class that creates thumbnails (UIImageView) and each thumbnail has a label. The label is created by another class. The label class creates a UIImageView and a UITextView on top of it. This is the init object class' init method: - (id)initWithFrame:(CGRect)frame { if ([super initWithFrame:frame] == nil) { return nil; } CGRect myFrame = CGRectMake(0, 0, 100, 100); myLabel = [[myLabelClass alloc] initWithFrame: myFrame]; //myLabelClass is a UIImageView based class [myLabel setCenter:CGPointMake(50, 50)]; [self addSubview: myLabel]; return self; } So, I have this MAIN VIEW CONTROLLER | |___ UIImageView WITH LABEL | |____ label background (UIView) |____ UITEXTVIEW (text) Now I want to write the contents of all these 3 components to a quartz context. I need to write using drawInRect, because I need to write the full object to a precise location. I expected object.layer.contents to be the image equivalent to these 3 "layers" flattened, in other words, the object's image, the label background and the label text, as it would if I created these 3 objects in Photoshop and flatten the composition. I also expect object.myLabel.layer.contents to contains the rendered contents of the UITextView over the label background. The problem is that when I use UIImage *myImage = [UIImage imageWithCGImage:objecto.myLabel.layer.contents]; [myImage drawInRect:CGRectMake(0, 0, 100, 100)]; I get nothing. How can I obtain a "flattened" image resultant to the full object (including its subviews)? thanks

• noncopyable static const member class in template class

  - by Dukales

  I have a non-copyable (inherited from boost::noncopyable) class that I use as a custom namespace. Also, I have another class, that uses previous one, as shown here: #include <boost/utility.hpp> #include <cmath> template< typename F > struct custom_namespace : boost::noncopyable { F sqrt_of_half(F const & x) const { using std::sqrt; return sqrt(x / F(2.0L)); } // ... maybe others are not so dummy const/constexpr methods }; template< typename F > class custom_namespace_user { static ::custom_namespace< F > const custom_namespace_; public : F poisson() const { return custom_namespace_.sqrt_of_half(M_PI); } static F square_diagonal(F const & a) { return a * custom_namespace_.sqrt_of_half(1.0L); } }; template< typename F > ::custom_namespace< F > const custom_namespace_user< F >::custom_namespace_(); this code leads to the next error (even without instantiation): error: no 'const custom_namespace custom_namespace_user::custom_namespace_()' member function declared in class 'custom_namespace_user' The next way is not legitimate: template< typename F ::custom_namespace< F const custom_namespace_user< F ::custom_namespace_ = ::custom_namespace< F (); What should I do to declare this two classes (first as noncopyable static const member class of second)? Is this feaseble?

• Cross-Platform Camera API

  - by Karim

  Hi, I'm now building a video transforming filter that have to transform video frames in real-time. One of the key requirements of the filter is to have high performance to minimize the number of dropped frames during the transform. Another requirement that is of lower priority but also nice to have is to make it cross-platform (both PC's and Mobile devices). The application is built in C++. Now my question is: is there any API that is more portable and has a similar or better performance characteristics than DirectShow? as DirectShow's portability is only limited to Windows-based devices (PCs and Windows Mobile&CE platforms). Also I've notices that for example using HTC's custom camera API has far better performance than what DirectShow offers. If you want to check this, try to build a filter in DirectShow that will multiply each color by 2 and render that in real-time from camera on the screen. Then do the same with HTC's API. There is almost 4-5x performance boost with vendor's specific API. So it'd be very nice if the library used the device-specific implementation of the driver, as performance is critical when doing this transforms on a mobile device (which is about ~500 MHz).

• divert asp.net child controls

  - by Eric

  Hi Folks, I am trying to create an asp.net custom control that acts as a hosting container for any other controls, similar to the existing ‘Panel’ control. Basically, I need to build a web control that groups a bunch of other controls. It will consist of a header and a body pane, similar to a normal window in desktop application. The header will contain some simple text and some JavaScript driven code that shows/hides the body pane. The body pane simply hosts any number of other controls. +------------------------------------------------------+ | User Details Show/Hide | +------------------------------------------------------+ | Name: [Eric ] | | Address: [Some where] | | Date of Birth: [01/01/1980] | | | | (any other fields goes on) | | | | | +------------------------------------------------------+ Ideally I want to create a control that packs the whole thing together, so at design time I could use the following markup. <myCtl:SuperContainer runat=”server” Title=”User Details”> <asp:label id=”lblName” runat=”server” text=”Name:”/> <asp:textbox id=”txtName” runat=”server”/> <asp:label id=”lblDOB” runat=”server” text=”Date of Birth:”/> <asp:textbox id=”txtDOB” runat=”server”/> (…other controls definition…) </myCtl:SuperContainer> I plan to include two panels in my control, one for the header and another one for the body, but as you can see, the key issue is to find a way to ‘divert’ the child controls that are defined in the markup to the body panel, instead of the default parent container. I feel it can be some how simply override (manipulate) the control property, but don’t know how to properly do so. Can any one give some idea about how to implement this ‘SuperContainer’ control? Many thank, Eric
