  - by jJack

  What is a Windows scripting language that: does not rely on .NET and offers the most OOP support and has simplest deployment? It doesn't necessarily need to be a scripting language; It can be in the form of a compiled executable, however it needs to be self contained--only ONE file, no DLL's and it cannot be declared to "include" other files. I cannot rely on the user having any .NET installed and it needs to be able to run on Windows 7 64 bit. By "most OOP support", I basically mean anything that has better OOP support than VBScript. A little context: Everything I have done thus far is in VBScript and writes a bunch of data into an .html file, which in the end is to be viewed by Internet Explorer. It also zips up a bunch of directories and files. It heavily relies on accessing the registry, file-system, and WMI (I can probably do without accessing WMI though, as long as I have good registry access). I can bring myself to code in any language so long as it meets me ridonkulous requirements stated above. I look forward to some good answers from those more experienced than I.

• How do I edit a row in NSTableView to allow deleting the data in that row and replacing with new d

  - by lampShade

  I'm building a to-do-list application and I want to be able to edit the entries in the table and replace them with new entries. I'm close to being able to do what I want but not quit. Here is my code so far: /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { [myArray addObject:[textField stringValue]]; [tableView reloadData]; } - (int)numberOfRowsInTableView:(NSTableView *)aTableView { return [myArray count]; } - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex { return [myArray objectAtIndex:rowIndex]; } - (id)init { [super init]; myArray = [[NSMutableArray alloc] init]; return self; } -(IBAction)removeItem:(id)sender { NSLog(@"This is the index of the selected row: %d",[tableView selectedRow]); NSLog(@"the clicked row is %d",[tableView clickedRow]); [myArray replaceObjectAtIndex:[tableView selectedRow] withObject:[textField stringValue]]; [myArray addObject:[textField stringValue]]; //[tableView reloadData]; } @end

• Can I compare a template variable to an integer in App Engine templates?

  - by matt b

  Using Django templates in Google App Engine (on Python), is it possible to compare a template variable to an integer in an {% if %} block? views.py: class MyHandler(webapp.RequestHandler): def get(self): foo_list = db.GqlQuery(...) ... template_values['foos'] = foo_list template_values['foo_count'] = len(foo_list) handler.response.out.write(template.render(...)) My template: {% if foo_count == 1 %} There is one foo. {% endif %} This blows up with 'if' statement improperly formatted. What I was attempting to do in my template was build a simple if/elif/else tree to be grammatically correct to be able to state #foo_count == 0: There are no foos. #foo_count == 1: There is one foo. #else: There are {{ foos|length }} foos. Browsing the Django template documents (this link provided in the GAE documentation appears to be for versions of Django far newer than what is supported on GAE), it appears as if I can only actually use boolean operators (if in fact boolean operators are supported in this older version of Django) with strings or other template variables. Is it not possible to compare variables to integers or non-strings with Django templates? I'm sure there is an easy way to workaround this - built up the message string on the Python side rather than within the template - but this seems like such a simple operation you ought to be able to handle in a template. It sounds like I should be switching to a more advanced templating engine, but as I am new to Django (templates or any part of it), I'd just like some confirmation first.

• Debugging unexpected error message - possible memory management problem?

  - by Ben Packard

  I am trying to debug an application that is throwing up strange (to my untutored eyed) errors. When I try to simply log the count of an array... NSLog(@"Array has %i items", [[self startingPlayers] count]); ...I sometimes get an error: -[NSCFString count]: unrecognized selector sent to instance 0x1002af600 or other times -[NSConcreteNotification count]: unrecognized selector sent to instance 0x1002af600 I am not sending 'count' to any NSString or NSNotification, and this line of code works fine normally. A Theory... Although the error varies, the crash happens at predictable times, immediately after I have run through some other code where I'm thinking I might have a memory management issue. Is it possible that the object reference is still pointing to something that is meant to be destroyed? Sorry if my terms are off, but perhaps it's expecting the array at the address it calls 'count' on, but finds another previous object that shouldn't still be there (eg an NSString)? Would this cause the problem? If so, what is the most efficient way to debug and find out what is that address? Most of my debugging up until now involves inserting NSLogs, so this would be a good opportunity to learn how to use the debugger.

• iPhone UI layout debugging

  - by Cruinh

  I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.origin.x, currentView.frame.origin.y, currentView.frame.size.width, currentView.frame.size.height); currentView = currentView.superview; } I expect this should show me the coordinates and size of each element up the hierarchy from the given view to the app's root UIWindow element, with the coordinates for each element relative to its parent. However, that does not seem to be the case. In my current situation, I have a UI I'm trying to debug where every other time I rotate the device, the whole UI shifts up or down 20 pixels, yet the code block above reports exactly the same numbers every time. I tried calling the above code after as much as a second delay, but that the numbers still come out the same each time. Does anyone know a better way to inspect the screen coordinates of UI elements? If I can detect when one is wrong, I can compensate for the problem when it appears.

• Need some help to determine the amount of recursive calls in PHP

  - by Ben Fransen

  Hi all, I've got a, I think fairly easy question, but this is bugging me for a while now. So I figured, maybe I can get some help here. Since recursive functions are always a bit tricky, and sometimes a bit unclear to me, I keep struggling to create a nice working solution to get my menudata. In one of my classes I have this function, which gives me all menu-items recursivly. The thing I want is to determine at which recursionlevel a certain object was retrieved so I can create a nicely looking HTML output with indents for the levels of nesting. public function GetObjectList($parentID = 0, $objectlist = null) { if(is_null($objectlist)) { $objectlist = new ObjectList("Model_Navigation"); } $query = MySQL::Query("SELECT * FROM `Navigation` WHERE `WebsiteID` = ".SITE_ID. " AND `LanguageID` = ".LANG_ID." AND `ParentID` = ".$parentID); while($result = MySQL::FetchAssoc($query)) { $object = new Model_Navigation(); $object->ID = $result["ID"]; $object->WebsiteID = $result["WebsiteID"]; $object->LanguageID = $result["LanguageID"]; $object->ParentID = $result["ParentID"]; $object->Name = $result["Name"]; $object->Page = Model_Page::GetObjectByID($result["PageID"]); $object->ExternalURL = $result["ExternalURL"]; $object->Index = $result["Index"]; $object->Level = [here lies my problem]; $objectlist->Add($object); self::GetObjectList($object->ID, $objectlist); } return $objectlist; } Hope to hear from you! Greetings from Holland, Ben Fransen

• iPhone: UITableView not Displaying New Data After Call to reloadData

  - by donnib

  My problem is that the cell.textLabel does not display the new data following a reload. I can see the cellForRowAtIndexPath being called so I know the reloadData call goes thru. If I log the rowString I see the correct value so the string I set label text to is correct. What am I doing wrong? I have following code : - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; static NSString *RowListCellIdentifier = @"RowListCellIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:RowListCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:RowListCellIdentifier]autorelease]; } NSMutableString *rowString = [[NSMutableString alloc] init]; [rowString appendString:[[[rows objectAtIndex:row] firstNumber]stringValue]]; [rowString appendString:@" : "]; [rowString appendString:[[[rows objectAtIndex:row] secondNumber]stringValue]]; [rowString appendString:@" : "]; [[cell textLabel] setText:rowString]; [rowString release]; return cell; } - (void)viewWillAppear:(BOOL)animated { [self.tableView reloadData]; [super viewWillAppear:animated]; }

• How do I forward `<Ctrl>-<Tab>` in Konsole?

  - by M. Tibbits

  I want to use intelligent tabbing in Emacs in C++ mode, but I also want to be able to insert a tab character when necessary. From other posts, I gather that the easiest way is to bind <Ctrl>-<Tab> to indent. However, it appears that Konsole in KUbuntu won't forward the <Ctrl>? My current .emacs file contains: (defun my-c-mode-common-hook () (setq c++-tab-always-indent t) (setq tab-width 4) (setq indent-tabs-mode t) ) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook) (global-set-key [C-tab] 'self-insert-command) So I believe that this will bind <Ctrl>-<Tab> to inserting a tab character. However, when I run: <Ctrl>-h k <Ctrl>-<Tab> Emacs only reports that I pressed the tab key. Is there some option to Konsole (which I have searched through to no avail) or global preferences in KUbuntu that I need to set so that the <Ctrl>- is also forwarded? (It certainly forwards all of the other <Ctrl>-blah commands.)

• Python Post Upload JPEG to Server?

  - by iJames

  It seems like this answer has been provided a bunch of times but in all of it, I'm still getting errors from the server and I'm sure it has to do with my code. I've tried HTTP, and HTTPConnection from httplib and both create quite different terminal outputs in terms of formatting/encoding so I'm not sure where the problem lies. Does anything stand out here? Or is there just a better way? Pieced together from an ancient article because I really needed to understand the basis of creating the post: http://code.activestate.com/recipes/146306-http-client-to-post-using-multipartform-data/ Note, the jpeg is supposed to be "unformatted". The pseudocode: boundary = "somerandomsetofchars" BOUNDARY = '--' + boundary CRLF = '\r\n' fields = [('aspecialkey','thevalueofthekey')] files = [('Image.Data','mypicture.jpg','/users/home/me/mypicture.jpg')] bodylines = [] for (key, value) in fields: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"' % key) bodylines.append('') bodylines.append(value) for (key, filename, fileloc) in files: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, filename)) bodylines.append('Content-Type: %s' % self.get_content_type(fileloc)) bodylines.append('') bodylines.append(open(fileloc,'r').read()) bodylines.append(BOUNDARY + '--') bodylines.append('') #print bodylines content_type = 'multipart/form-data; boundary=%s' % BOUNDARY body = CRLF.join(bodylines) #conn = httplib.HTTP("www.ahost.com") # In both this and below, the file part was garbling the rest of the body?!? conn = httplib.HTTPConnection("www.ahost.com") conn.putrequest('POST', "/myuploadlocation/uploadimage") headers = { 'content-length': str(len(body)), 'Content-Type' : content_type, 'User-Agent' : 'myagent' } for headerkey in headers: conn.putheader(headerkey, headers[headerkey]) conn.endheaders() conn.send(body) response = conn.getresponse() result = response.read() responseheaders = response.getheaders() It's interesting in that the real code I've implemented seems to work and is getting back valid responses, but the problem it it's telling me that it can't find the image data. Maybe this is particular to the server, but I'm just trying to rule out that I'm not doing some thing exceptionally stupid here. Or perhaps there's other methodologies for doing this more efficiently. I've not tried poster yet because I want to make sure I'm formatting the POST correctly first. I figure I can upgrade to poster after it's working yes?

• When is Facebook Connect supposed to call its delegate methods?

  - by RickiG

  Hi The Facebook connect code is eluding me a bit. I have no problem doing a login, and a wall post, however, I simply can not figure out how the delegate methods for the FBDialog andFBStreamDialog is supposed to work. - (void)postToWall { FBStreamDialog *dialog = [[[FBStreamDialog alloc] init] autorelease]; dialog.delegate = self; dialog.userMessagePrompt = @"Enter your message:"; dialog.attachment = [NSString stringWithFormat:@"JSONpost code"]; [dialog show]; } I adhere to these protocols in my controller: <FBDialogDelegate, FBSessionDelegate, FBRequestDelegate> I then implement the two methods: - (void) dialogDidCancel:(FBDialog *)dialog { NSLog(@"Failed"); } - (void) dialogDidSucceed:(FBDialog *)dialog { NSLog(@"Success"); } After I tap "publish" and the postToWall methods is done executing the Facebook "pop up" in the UI is empty, except a small "X" in the top right corner and a "F" (facebook logo) in the top left corner. The UI will stay there until I tap the "X", this results in the dialogDidCancel delegate method being called. The post data is showing up on the Facebook page, everything seems to work. Why is thedialogDidSucceedmethod never called? I need this to release my facebook controller and restore the UI back to where the user was before "starting" FB Connect. Thank You:)

• Cocos2d shake/accelerometer issue.

  - by Ryan Poolos

  So I a little backstory. I wanted to implement a particle effect and sound effect that both last about 3 sec or so when the user shakes their iDevice. But first issue arrived when the build in UIEvent for shakes refused to work. So I took the advice of a few Cocos veterans to just use some script to get "violent" accelerometer inputs as shakes. Worked great until now. The problem is that if you keep shaking it just stacks the particle and sounds over and over. Now this wouldn't be that big of a deal except it happens even if you are careful to try and not do so. So what I am hoping to do is disable the accelerometer when the particle effect/sound effect start and then reenable it as soon as they finish. Now I don't know if I should do this by schedule, NStimer, or some other function. I am open to ALL suggestions. here is my current "shake" code. - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration { const float violence = 1; static BOOL beenhere; BOOL shake = FALSE; if (beenhere) return; beenhere = TRUE; if (acceleration.x > violence * 1.5 || acceleration.x < (-1.5* violence)) shake = TRUE; if (acceleration.y > violence * 2 || acceleration.y < (-2 * violence)) shake = TRUE; if (acceleration.z > violence * 3 || acceleration.z < (-3 * violence)) shake = TRUE; if (shake) { id particleSystem = [CCParticleSystemQuad particleWithFile:@"particle.plist"]; [self addChild: particleSystem]; // Super simple Audio playback for sound effects! [[SimpleAudioEngine sharedEngine] playEffect:@"Sound.mp3"]; shake = FALSE; } beenhere = FALSE; }

• WPF DataBinding to standard CLR properties in code-behind

  - by nukefusion

  Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

• Anything speaking against the bitnami.org Ruby/Rails/Redmine Stack?

  - by Pekka

  I am looking to set up a Redmine server on a Windows virtual machine on my local workstation. (Background in this related question.) I have zero knowledge of Ruby nor Rails, and while Redmine may be the opportunity to dip into those platforms somewhat, my first goal is to get it running as quickly and easily as possible. For that, I am eyeing the Bitnami Redmine Package. It promises point-and-click install, and a self-contained environment with everything you need. Apart from the learning factor, are there any serious limitations this method implies? Any serious cutdowns in customizability? I will be wanting to customize the template right away, for example, and install plugins. The package looks o.k. to me but before I install it, I was curious to know whether anybody would advise against it and why. Edit: The first impression is great. From 0 to a working Redmine installation in twelve minutes! Wow.

• How to host WCF service and TCP server on same socket?

  Tooday I use ServiceHost for self hosting WCF cervices. I want to host near to my WCF services my own TCP programm for direct sockets operations (like lien to some sort of broadcasting TCP stream) I need control over namespaces (so I would be able to let my clients to send TCP streams directly into my service using some nice URLs like example.com:port/myserver/stream?id=1 or example.com:port/myserver/stream?id=anything and so that I will not be bothered with Idea of 1 client for 1 socket at one time moment, I realy want to keep my WCF services on the same port as my own server or what it is so to be able to call www.example.com:port/myWCF/stream?id=222...) Can any body please help me with this? I am using just WCF now. And I do not enjoy how it works. That is one of many resons why I want to start migration to clear TCP=) I can not use net-tcp binding or any sort of other cool WS-* binding (tooday I use the simpliest one so that my clients like Flash, AJAX, etc connect to me with ease). I needed Fast and easy in implemrnting connection protocol like one I created fore use with Sockets for real time hi ammount of data transfering. So.. Any Ideas? Please - I need help.

• Reading Certificates on iOS Problem

What am I missing? - (void)findCertificate:(NSString *)url { NSInputStream*input = [[NSInputStream inputStreamWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://store.writeitstudios.com"]]] retain]; [input setDelegate:self]; [input scheduleInRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode]; [input open]; NSLog(@"Status: %i",[input streamStatus]); } - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { NSLog(@"handle Event: %i",eventCode); if (eventCode == NSStreamStatusOpen) { NSArray *certificates = (NSArray*)CFReadStreamCopyProperty((CFReadStreamRef)aStream, kCFStreamPropertySSLPeerCertificates); NSLog(@"Certs: %@",CFReadStreamCopyProperty((CFReadStreamRef)aStream, kCFStreamPropertySSLPeerCertificates)); if ([certificates count] > 0) { SecCertificateRef certificate = (SecCertificateRef)[certificates objectAtIndex:0]; NSString *description = (NSString*)SecCertificateCopySubjectSummary(certificate); NSData *data = (NSData *)SecCertificateCopyData(certificate); NSLog(@"Description: %@",description); } } } And yes, I am aware that I am leaking memory.

• Pass Result of ASIHTTPRequest "requestFinished" Back to Originating Method

  - by Intelekshual

  I have a method (getAllTeams:) that initiates an HTTP request using the ASIHTTPRequest library. NSURL *httpURL = [[[NSURL alloc] initWithString:@"/api/teams" relativeToURL:webServiceURL] autorelease]; ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:httpURL] autorelease]; [request setDelegate:self]; [request startAsynchronous]; What I'd like to be able to do is call [WebService getAllTeams] and have it return the results in an NSArray. At the moment, getAllTeams doesn't return anything because the HTTP response is evaluated in the requestFinished: method. Ideally I'd want to be able to call [WebService getAllTeams], wait for the response, and dump it into an NSArray. I don't want to create properties because this is disposable class (meaning it doesn't store any values, just retrieves values), and multiple methods are going to be using the same requestFinished (all of them returning an array). I've read up a bit on delegates, and NSNotifications, but I'm not sure if either of them are the best approach. I found this snippet about implementing callbacks by passing a selector as a parameter, but it didn't pan out (since requestFinished fires independently). Any suggestions? I'd appreciate even just to be pointed in the right direction. NSArray *teams = [[WebService alloc] getAllTeams]; (currently doesn't work, because getAllTeams doesn't return anything, but requestFinished does. I want to get the result of requestFinished and pass it back to getAllTeams:)

• Auto-resolving a hostname in WCF Metadata Publishing

  - by Mike C

  I am running a self-hosted WCF service. In the service configuration, I am using localhost in my BaseAddresses that I hook my endpoints to. When trying to connect to an endpoint using the WCF test client, I have no problem connecting to the endpoint and getting the metadata using the machine's name. The problem that I run into is that the client that is generated from metadata uses localhost in the endpoint URLs it wants to connect to. I'm assuming that this is because localhost is the endpoint URL published by metadata. As a result, any calls to the methods on the service will fail since localhost on the calling machine isn't running the service. What I would like to figure out is if it is possible for the service metadata to publish the proper URL to a client depending on the client who is calling it. For example, if I was requesting the service metadata from a machine on the same network as the server the endpoint should be net.tcp://MYSERVER:1234/MyEndpoint. If I was requesting it from a machine outside the network, the URL should be net.tcp://MYSERVER.mydomain.com:1234/MyEndpoint. And obviously if the client was on the same machine, THEN the URL could be net.tcp://localhost:1234/MyEndpoint. Is this just a flaw in the default IMetadataExchange contract? Is there some reason the metadata needs to publish the information in a non-contextual way? Is there another way I should be configuring my BaseAddresses in order to get the functionality I want? Thanks, Mike

• How should a one-man development shop document their code?

  - by CKoenig

  Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

• iPhone: Creating a hierarchy-based table navigation.

  - by Jack Griffiths

  Hi there, I've tried to ask this before, but nothing got answered. Basically, I would like someone to explain to me how to create a table, which when a cell is tapped, pushes the user to the next view for that cell. I have this so far: Click here to view what I have. I would further like to, say when CSS is tapped, it goes to a new view which has another table in it. This table would then take the user to a detail view, which is scrollable and you can switch pages through it. I would appreciate longer, more structured tutorials on how to do each and every bit to get it to work. Here's my array in my implementation file: - (void)viewDidLoad { arryClientSide = [[NSArray alloc] initWithObjects:@"CSS", @"HTML", @"JavaScript", @"XML", nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Apache", @"PHP", @"SQL", nil]; self.title = @"Select a Language"; [super viewDidLoad]; } and my .h: @interface RootViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITableView *tblSimpleTable; NSArray *arryClientSide; NSArray *arryServerSide; } My current code crashes the script, and this error is returned in the console: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "NextView" nib but didn't get a UITableView.' If that error is the source of why it's not pushing, then an explanation of how to remedy that would also be appreciated Many thanks, Jack

• How to call a service operation at a REST style WCF endpoint uri?

  - by Dieter Domanski

  Hi, is it possible to call a service operation at a wcf endpoint uri with a self hosted service? I want to call some default service operation when the client enters the endpoint uri of the service. In the following sample these uris correctly call the declared operations (SayHello, SayHi): - http://localhost:4711/clerk/hello - http://localhost:4711/clerk/hi But the uri - http://localhost:4711/clerk does not call the declared SayWelcome operation. Instead it leads to the well known 'Metadata publishing disabled' page. Enabling mex does not help, in this case the mex page is shown at the endpoint uri. private void StartSampleServiceHost() { ServiceHost serviceHost = new ServiceHost(typeof(Clerk), new Uri( "http://localhost:4711/clerk/")); ServiceEndpoint endpoint = serviceHost.AddServiceEndpoint(typeof(IClerk), new WebHttpBinding(), ""); endpoint.Behaviors.Add(new WebHttpBehavior()); serviceHost.Open(); } [ServiceContract] public interface IClerk { [OperationContract, WebGet(UriTemplate = "")] Stream SayWelcome(); [OperationContract, WebGet(UriTemplate = "/hello/")] Stream SayHello(); [OperationContract, WebGet(UriTemplate = "/hi/")] Stream SayHi(); } public class Clerk : IClerk { public Stream SayWelcome() { return Say("welcome"); } public Stream SayHello() { return Say("hello"); } public Stream SayHi() { return Say("hi"); } private Stream Say(string what) { string page = @"<html><body>" + what + "</body></html>"; return new MemoryStream(Encoding.UTF8.GetBytes(page)); } } Is there any way to disable the mex handling and to enable a declared operation instead? Thanks in advance, Dieter

• wpf error template - red box still visible on collapse of an expander

  - by Andy Clarke

  Hi, I'm doing some validation on the DataSource of TextBox that's within an Expander and have found that once a validation error has been triggered, if I collapse the Expander, the red box stays where the TextBox would have been. <Expander Header="Blah Blah Blah"> <TextBox Name="TextBox" Validation.ErrorTemplate="{DynamicResource TextBoxErrorTemplate}" Text="{Binding Path=Blah, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" /> </Expander> I've tried to get round this by binding the visibility of the Error Template to the Expander, however I think there's something wrong with the binding. <local:NotVisibleConverter x:Key="NotVisibleConverter" /> <ControlTemplate x:Key="TextBoxErrorTemplate"> <DockPanel> <Border BorderBrush="Red" BorderThickness="2" Visibility="{Binding Path=IsExpanded, Converter={StaticResource NotVisibleConverter}, RelativeSource={RelativeSource AncestorType=Expander}}" > <AdornedElementPlaceholder Name="MyAdorner" /> </Border> </DockPanel> <ControlTemplate.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> I guess I've gone wrong with my binding, can someone put me back on track please? Alternatively does anyone know another solution to the ErrorTemplate still being visible on the collapse of an Expander?

• Delphi: Problems with TList of Frames

  - by Dan Kelly

  I'm having a problem with an interface that consists of a number of frames (normally 25) within a TScrollBox. There are 2 problems, and I am hoping that one is a consequence of the other... Background: When the application starts up, I create 25 frames, each containing approx. 20 controls, which are then populated with the default information. The user can then click on a control to limit the search to a subset of information at which point I free and recreate my frames (as the search may return < 25 records) The problem: If I quit the application after the initial search then it takes approx. 5 seconds to return to Delphi. After the 2nd search (and dispose / recreate of frames) it takes approx. 20 seconds) Whilst I could rewrite the application to only create the frames once, I would like to understand what is going on. Here is my create routine: procedure TMF.CreateFrame(i: Integer; var FrameBottom: Integer); var NewFrame: TSF; begin NewFrame := TSF.Create(Self); NewFrame.Name := 'SF' + IntToStr(i); if i = 0 then NewSF.Top := 8 else NewSF.Top := FrameBottom + 8; FrameBottom := NewFrame.Top + NewFrame.Height; NewFrame.Parent := ScrollBox1; FrameList.Add(NewFrame); end; And here is my delete routine: procedure TMF.ClearFrames; var i: Integer; SF: TSF; begin for i := 0 to MF.FrameList.Count -1 do begin SF := FrameList[i]; SF.Free; end; FrameList.Clear; end; What am I missing?
