  • wpf c# databinding on object

    - by Enriquev
    Hello, say I have this control: public partial class bloc999 : UserControl { bloc999Data mainBlock = new bloc999Data(); public bloc999() { InitializeComponent(); mainBlock.txtContents = "100"; base.DataContext = mainBlock; } } in the xaml: <TextBox Margin="74,116,106,0" Name="txtContents" Text="{Binding Path=txtContents, UpdateSourceTrigger=PropertyChanged,Mode = TwoWay}" /> <TextBox Margin="74,145,106,132" Name="txtContents2" Text="{Binding Path=txtContents2, UpdateSourceTrigger=PropertyChanged,Mode = TwoWay}" /> Then I have this class: public class bloc999Data : INotifyPropertyChanged { string _txtContents; string _txtContents2; public event PropertyChangedEventHandler PropertyChanged; void NotifyPropertyChanged(string propName) { if (this.PropertyChanged != null) this.PropertyChanged( this, new PropertyChangedEventArgs(propName)); } public string txtContents2 { get { return this._txtContents2; } set { if (int.Parse(value) > int.Parse(this._txtContents)) { this._txtContents2 = "000"; } else this._txtContents2 = value; NotifyPropertyChanged("txtContents2"); } } public string txtContents { get { return this._txtContents; } set { this._txtContents = value; NotifyPropertyChanged("txtContents"); } } } Ok now say I have A button on the form and I do this in the code: mainBlock.txtContents2 = "7777777"; It puts 000 in the textbox, but If i just type in manually, in the textbox (txtContents2, the setter code is called but for some reason the textboxes value does not change, the instance value does change. help?

  • How to route tree-structured URLs with ASP.NET Routing?

    - by Venemo
    Hello Everyone, I would like to achieve something very similar to this question, with some enhancements. There is an ASP.NET MVC web application. I have a tree of entities. For example, a Page class which has a property called Children, which is of type IList<Page>. (An instance of the Page class corresponds to a row in a database.) I would like to assign a unique URL to every Page in the database. I handle Page objects with a Controller called PageController. Example URLs: http://mysite.com/Page1/ http://mysite.com/Page1/SubPage/ http://mysite.com/Page/ChildPage/GrandChildPage/ You get the picture. So, I'd like every single Page object to have its own URL that is equal to its parent's URL plus its own name. In addition to that, I also would like the ability to map a single Page to the / (root) URL. I would like to apply these rules: If a URL can be handled with any other route, or a file exists in the filesystem in the specified URL, let the default URL mapping happen If a URL can be handled by the virtual path provider, let that handle it If there is no other, map the other URLs to the PageController class I also found this question, and also this one and this one, but they weren't of much help, since they don't provide an explanation about my first two points. I see the following possible soutions: Map a route for each page invidually. This requires me to go over the entire tree when the application starts, and adding an exact match route to the end of the route table. I could add a route with {*path} and write a custom IRouteHandler that handles it, but I can't see how could I deal with the first two rules then, since this handler would get to handle everything. So far, the first solution seems to be the right one, because it is also the simplest. I would really appreciate your thoughts on this. Thank you in advance!

  • iPhone SDK: How do you download video files to the Document Directory and then play them?

    - by Jessica
    I've been fooling around with code for ages on this one, I would be very grateful if someone could provide a code sample that downloaded this file from a server http://www.archive.org/download/june_high/june_high_512kb.mp4, (By the way it's not actually this file, it's just a perfect example for anyone trying to help me) and then play it from the documents directory. I know it seems lazy of me to ask this but I have tried so many different variations of NSURLConnection that it's driving me crazy. Also, if I did manage to get the video file downloaded would I be correct in assuming this code would then successfully play it: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"june_high_512kb.mp4"]; NSURL *movieURL = [NSURL fileURLWithPath:path]; self.theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [_theMovie play]; If the above code would work in playing a video file from the document directory, then I guess the only thing I would need to know is, how to download a video file from a server. Which is what seems to be my major problem. Any help is greatly appreciated.

  • Clarification needed: How does .NET runtime resolve assembly references from parent folder?

    - by aoven
    I have the following output structure of executables in my solution: %ProgramFiles% | +-[MyAppName] | +-[Client] | | | +-(EXE & several DLL assemblies) | +-[Common] | | | +-[Schema Assemblies] | | | | | +-(several DLL assemblies) | | | +-(several DLL assemblies) | +-[Server] | +-(EXE & several DLL assemblies) Each project in solution references different DLL assemblies, some of which are outputs from other projects in solution, and others are plain 3rd-party assemblies. For example, [Client] EXE might reference an assembly in [Common], which is in a different directory branch. All references have "Copy Local" set to false, to mirror the layout of the files in the final installed application. Now, if I take a look at reference properties in the Visual Studio IDE, I see that "Path" of every reference is absolute and that it corresponds to the actual output location of the assembly. That's understandable and correct. As expected, solution compiles and runs just fine. What I don't understand is, why everything seems to work even when I close the IDE, rename the [MyAppName] directory and run the [Client] EXE manually? How does the runtime find the assemblies if the reference paths aren't the same as they were at the time of linking? To be clear - this is actually exactly what I'm after: a semi-dispersed set of application files that run fine regardless of where the [MyAppName] directory is located or even what it's named. I'd just like to know, how and why this works without any specific path resolution on my part. I've read the answers to this similar question, but I still don't get it. Help much appreciated!

  • How to find the leaky faucet that loads into Malloc 32kb

    - by Rob
    I have been messing around with Leaks trying to find which function is not being deallocated (I am still new to this) and could really use some experienced insight. I have this bit of code that seems to be the culprit. Every time I press the button that calls this code, 32kb of memory is additionally allocated to memory and when the button is released that memory does not get deallocated. What I found was that everytime that AVAudioPlayer is called to play an m4a file, the final function to parse the m4a file is MP4BoxParser::Initialize() and this in turn allocates 32kb of memory through Cached_DataSource::ReadBytes My question is, how do I go about deallocating that after it is finished so that it doesn't keep allocating 32kb every time the button is pressed? Any help you could provide is greatly appreciated! - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //stop playing theAudio.stop; // cancel any pending handleSingleTap messages [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSingleTap) object:nil]; UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [g_AppsList objectAtIndex: [touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource: filename ofType:@"m4a"]; theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:-1]; [theAudio setVolume: g_Volume]; [theAudio play]; }

  • Why can't I Bind a viewmodel property to a dependency property of a custom control

    - by Robert
    I want to use a color picker in my wpf application and I saw a nice looking one on this codeproject page. The control works fine until I want to connect the control to a viewmodel. I created a small test program with this viewmodel: public class ColorViewModel : ViewModelBase { public ColorViewModel() { LineColor = Brushes.Yellow; } SolidColorBrush _brushColor; public SolidColorBrush LineColor { get { return _brushColor; } set { _brushColor = value; RaisePropertyChanged(() => LineColor); } } } The test program has a textbox and the colorpicker controls: <StackPanel Orientation="Horizontal"> <TextBlock Text="Please Select a Color" FontWeight="Bold" Margin="10" Foreground="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged}"/> <vw:ColorPickerControlView x:Name="ForeColorPicker" Margin="10" CurrentColor="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged }"/> </StackPanel> In the loaded event of the window I set the viewmodel to the datacontext like this: DataContext = new ColorViewModel(); The problem is that I can't seem to bind the LineColor property of the viewmodel to the CurrentColor property of the ColorPickerControlView. The CurrentControl property of the ColorPickerControlView seems to be fine. The constructor looks like this: public ColorPickerControlView() { this.DataContext = this; InitializeComponent(); CommandBindings.Add(new CommandBinding(SelectColorCommand, SelectColorCommandExecute)); } In the constructor of the UserControl there is the line this.DataContext = this; I read that is is necessary to bind the dependency properties. Do I override this line when I set my viewmodel to the datacontext and is that why I can't bind to the CurrentColor property? Is there any workaround? Or did I make another mistake?

  • iphone download several files

    - by Floo
    hi all !  In my app i need to download several plist.  to download a plist i use the NSURLconnection  in my code i use an UIAlertView with a UIActivityIndicator then when the download is finished i add a button to the alert to dismiss it.  To download the plist i use somewhere in my code an NSURL set to the adresse where the plist is, next i set a NSURLRequest with the url cache policy and a timeout interval.  Then i set my NSMutableData to the NSURL connection with a NSURLRequest.  In the delegate didReceiveData: i append data to my mutable data object, in the didFailWithError: i handle error. And finaly in the connectionDidFinishLoading  i serialize my data to a plist so i can write to file my plist, and release my alertview.  My problem is : how can i do if i have sevetal file to download because the connectionDidFinishLoading is called each time my NSURLConnection is finished but i want to release my UiAlert when everything is finished. But when the first plist is downloaded my code in the connectionDidFinishLoading will fire.  here is my code :  in the view did load :  // set the UiAlert in the view did load  NSURL *theUrl = [NSURL URLWithString:@"http://adress.com/plist/myPlist.plist"]; NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; self.plistConnection = [[ NSURLConnection alloc] initwithRequest:theRequest delegate:self startImmediatly:YES]; //plistConnection is a NSURLConnection - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {  [incomingPListData appendData:data]; } -(void)connection:(NSURLConnection *)connectionDidFailWithError:(NSError *)error { // handle error here  } -(void)connectionDidFinisloading:(NSURLConnection *) connection {  NSPropertyListFormat format; NSString *serialErrorString;  NSData *plist = [NSPropertyListSerialisation propertyListFromData:incomingPlistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&serialErrorString]; if (serialErrorString) {//error} else { // create path and write plist to path} // change message and title of the alert so if i want todownload an another file  where do i put the request the connection and how can i tell the didFinishLoading to fire code when all my file are downloaded.  thanks to all

  • Installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4

    - by Christine Q.
    I have faced serious difficulties while installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4 w/ Doctrine ORM. The installation directly from the server did not work out like with previous plugins that I have installed: C:\pathsymfony plugin:install sfJqueryTreeDoctrineManagerPlugin plugin installing plugin "sfJqueryTreeDoctrineManagerPlugin" No release available for plugin "sfJqueryTreeDoctrineManagerPlugin" This is why I needed to install the plugin by downloading the tgz-archive and install it manually like this: C:\pathsymfony plugin:install "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" plugin installing plugin "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" sfSymfonyPluginManager Installing web data for plugin I guess everything should be fine this far? After that I edited \apps\admin\config\settings.yml like instructed in the plugins readme file. all: .settings: enabled_modules: [default, sfJqueryTreeDoctrineManager] I also checked that the plugin was enabled in \config\ProjectConfiguration.class.php like this: $this->enablePlugins(array( // other plugins, 'sfJqueryTreeDoctrineManagerPlugin' )); I published assets and cleared cache: C:\pathsymfony plugin:publish-assets >> plugin Configuring plugin - sfJqueryTreeDoctrineManagerPlugin C:\pathsymfony cc Finally I added the required helper to the newly created apps\admin\modules\category\templates\indexSuccess.php <?php use_helper("sfJqueryTreeDoctrine"); echo get_nested_set_manager("Category", "name"); When loading the page I unfortunately get the following error: 500 | Internal Server Error | InvalidArgumentException Unable to load "sfJqueryTreeDoctrineHelper.php" helper in: SF_ROOT_DIR\apps\admin\modules/businessunitgroup/lib/helper, SF_ROOT_DIR\apps\admin\lib/helper, SF_ROOT_DIR\lib/helper, SF_SYMFONY_LIB_DIR/helper. The file sfJqueryTreeDoctrineHelper.php exists indeed but not in any previously mentioned folder. The file can only be found in the folder \plugins\sfJqueryTreeDoctrineManagerPlugin\lib\helper. I guess that Symfony doesn't look to that folder while finding helpers? I have tried to move the helper file to one of the previously mentioned folders. As expected, that changes the error. Now I get: 500 | Internal Server Error | sfConfigurationException The component does not exist: "sfJqueryTreeDoctrineManager", "manager". Unfortunately I can't figure out how should I be able to retrieve the "missing" component from the correct folder. I would be very grateful for any advice to help me forward. By the way, I am aware that there are other nested-set / tree plugins available for Symfony (like sfDoctrineTreePlugin and caPropelTreePlugin) but unluckily those are either uncompatible or too limited for my needs.

  • Eclipse does not start on Windows 7

    Suddenly Eclipse today has decides to stop working. The last thing I did was close all perspectives and close Eclipse. When loading eclipse from the command prompt, using: "eclipse.exe -clean" the splash screen loads for a split second then exits. When I run the command: eclipsec -consoleLog -debug it results in the following output: Start VM: -Dosgi.requiredJavaVersion=1.6 -Dhelp.lucene.tokenizer=standard -Xms4096m -Xmx4096m -XX:MaxPermSize=512m -Djava.class.path=d:\devtools\eclipse\\plugins/org.eclipse.equinox.launcher_1.3. 0.v20130327-1440.jar -os win32 -ws win32 -arch x86_64 -showsplash d:\devtools\eclipse\\plugins\org.eclipse.platform_4.3.0.v20130605-20 00\splash.bmp -launcher d:\devtools\eclipse\eclipsec.exe -name Eclipsec --launcher.library d:\devtools\eclipse\\plugins/org.eclipse.equinox.launcher.win 32.win32.x86_64_1.1.200.v20130521-0416\eclipse_1503.dll -startup d:\devtools\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v201303 27-1440.jar --launcher.appendVmargs -product org.eclipse.epp.package.standard.product -consoleLog -debug -vm C:/Program Files/Java/jdk1.6.0_37/bin\..\jre\bin\server\jvm.dll -vmargs -Dosgi.requiredJavaVersion=1.6 -Dhelp.lucene.tokenizer=standard -Xms4096m -Xmx4096m -XX:MaxPermSize=512m -Djava.class.path=d:\devtools\eclipse\\plugins/org.eclipse.equinox.launcher_1.3. 0.v20130327-1440.jar Error occurred during initialization of VM Incompatible minimum and maximum heap sizes specified Checking Task Manager shows no Java process running and both the CPU and memory usage are very low.

  • My jquery cookies are not resetting, even though am using the correct code.

    - by Adam Libonatti-Roche
    My problem is that I am trying to reset some form cookies so when someone has completed their form, they are reset so it is possible for someone else to complete the form. Simple and obvious. But However many different lines of code I put in, the cookies just do not seem to be disappearing. I am using the remember function from the site below: Komodo Media So the details stay when they move away from the page: the code i have for the page starting is as follows: <script type="text/javascript"> function remember( selector ){ $(selector).each( function(){ //if this item has been cookied, restore it var name = $(this).attr('name'); if( $.cookie( name ) ){ if( $(this).is(':checkbox') ){ $(this).attr('checked',$.cookie( name )); }else{ $(this).val( $.cookie(name) ); } } //assign a change function to the item to cookie it $(this).change( function(){ if( $(this).is(':checkbox') ){ $.cookie(name, $(this).attr('checked'), { path: '/', expires: 1 }); }else{ $.cookie(''+name+'', $(this).val(), { path: '/', expires: 1 }); } }); }); } // JQUERY FOR THIS PAGE $(document).ready( function(){ remember("[name=username]"); remember("[name=firstname]"); remember("[name=lastname]"); remember("[name=email]"); remember("[name=password]"); remember("[name=address1]"); remember("[name=address2]"); remember("[name=postcode]"); remember("[name=country]"); } ); </script> And the code for resetting them is simple enough, as it takes the cookie name and sets it to null. However, this does not work as on returning to the form, all fields from before are still there. Any help with this would be brilliant.

  • How to checkout from SVN with an ANT task?

    - by Josh
    I'm interested in any way that I can create an Ant task to checkout files from SubVersion. I "just" want to do the checkout from the command line. I've been using Eclipse with Ant and SubVersion for a while now, but my Ant and SubVersion knowledge is somewhat lacking as I relied on Eclipse to wire it all together. I've been looking at SvnAnt as one solution, which is part of Subclipse from Tigris at http://subclipse.tigris.org/svnant/svn.html. It may work fine, but all I get are NoClassDefFoundErrors. To the more experienced this probably looks like a simple Ant configuration problem, but I don't know about that. I copied the svnant.jar and svnclientadapter.jar into my Ant lib directory. Then I tried to run the following: <?xml version="1.0"?> <project name="blah"> <property environment="env"/> <path id="svnant.classpath"> <pathelement location="${env.ANT_HOME}/lib"/> <fileset dir="${env.ANT_HOME}/lib/"> <include name="svnant.jar"/> </fileset> </path> <typedef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="svnant.classpath" /> <target name="checkout"> <svn username="abc" password="123"> <checkout url="svn://blah/blah/trunk" destPath="workingcopy"/> </svn> </target> </project> To which I get the following response: build.xml:17: java.lang.NoClassDefFoundError: org/tigris/subversion/javahl/SVNClientInterface I am running SVN 1.7 and SvnAnt 1.3 on Windows XP 32-bit. Thanks for any pointers!

  • Git Diff with Beyond Compare

    - by Avanst
    I have succeeded in getting git to start Beyond Compare 3 as a diff tool however, when I do a diff, the file I am comparing against is not being loaded. Only the latest version of the file is loaded and nothing else, so there is nothing in the right pane of Beyond Compare. I am running git 1.6.3.1 with Cygwin with Beyond Compare 3. I have set up beyond compare as they suggest in the support part of their website with a script like such: #!/bin/sh # diff is called by git with 7 parameters: # path old-file old-hex old-mode new-file new-hex new-mode "path_to_bc3_executable" "$2" "$5" | cat Has anyone else encountered this problem and know a solution to this? Edit: I have followed the suggestions by VonC but I am still having exactly the same problem as before. I am kinda new to Git so perhaps I am not using the diff correctly. For example, I am trying to see the diff on a file with a command like such: git diff main.css Beyond Compare will then open and only display my current main.css in the left pane, there is nothing in the right pane. I would like the see my current main.css in the left pane compared to the HEAD, basically what I have last committed. My git-diff-wrapper.sh looks like this: #!/bin/sh # diff is called by git with 7 parameters: # path old-file old-hex old-mode new-file new-hex new-mode "c:/Program Files/Beyond Compare 3/BCompare.exe" "$2" "$5" | cat My git config looks like this for Diff: [diff] external = c:/cygwin/bin/git-diff-wrapper.sh

  • python __import__() imports from 2 different directories when same module exists in 2 locations

    - by programer_gramer
    Hi, I have a python application , which has directory structure like this. -pythonapp -mainpython.py -module1 -submodule1 -file1.py -file2.py -submodule2 -file3.py -file3.py -submodule3 -file1.py -file2.py -file5.py -file6.py -file7.py when I try to import the python utilities(from mainpython.py) under submodule3 , I get the initial 2 files from submodule1.(please note that submodule1 and 3 have 2 different files with the same name). However the same import works fine when there is no conflict i.e it correctly imports file 5,6,7 from submodule3. Here is the code : name=os.path.splitext(os.path.split("module1\submodule3\file1.py")[1])[0] -- file1.py name here is passed dynamically. module = import(name) //Here is name is like "file1" it works(but with the above said issue, though, when passes the name of the file dynamically), but if I pass complete package as "module1.submodule1.file1" it fails with an ImportError saying that "no module with name file1" Now the question is how do we tell the interpreter to use only the ones under "module1.submodule3.file2"? I am using python This is really urgent one and I have run out of all the tries. Hope some experienced python developers can solve this for me?

  • Get current PHP executable from within script?

    - by benizi
    I want to run a PHP cli program from within PHP cli. On some machines where this will run, both php4 and php5 are installed. If I run the outer program as php5 outer.php I want the inner script to be run with the same php version. In Perl, I would use $^X to get the perl executable. It appears there's no such variable in PHP? Right now, I'm using $_SERVER['_'], because bash (and zsh) set the environment variable $_ to the last-run program. But, I'd rather not rely on a shell-specific idiom. UPDATE: Version differences are but one problem. If PHP isn't in PATH, for example, or isn't the first version found in PATH, the suggestions to find the version information won't help. Additionally, csh and variants appear to not set the $_ environment variable for their processes, so the workaround isn't applicable there. UPDATE 2: I was using $_SERVER['_'], until I discovered that it doesn't do the right thing under xargs (which makes sense... zsh sets it to the command it ran, which is xargs, not php5, and xargs doesn't change the variable). Falling back to using: $version = explode('.', phpversion()); $phpcli = "php{$version[0]}";

  • Run AppleScript with Elevated Privileges from Objective C

    - by cygnl7
    I'm attempting to execute an uninstaller (written in AppleScript) through AuthorizationExecuteWithPrivileges. I'm setting up my rights after creating an empty auth ref like so: char *tool = "/usr/bin/osascript"; AuthorizationItem items = {kAuthorizationRightExecute, strlen(tool), tool, 0}; AuthorizationRights rights = {sizeof(items)/sizeof(AuthorizationItem), &items}; AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights | kAuthorizationFlagPreAuthorize | kAuthorizationFlagInteractionAllowed; status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL); Later I call: status = AuthorizationExecuteWithPrivileges(authorizationRef, tool, kAuthorizationFlagDefaults, (char *const *)args, NULL); On Snow Leopard this works fine, but on Leopard I get the following in syslog.log: Apr 19 15:30:09 hostname /usr/bin/osascript[39226]: OpenScripting.framework - 'gdut' event blocked in process with mixed credentials (issetugid=0 uid=501 euid=0 gid=20 egid=20) Apr 19 15:30:12: --- last message repeated 1 time --- ...

(-1708) After researching this for a few hours my first guess is that Leopard somehow doesn't want to do what I'm doing because it knows it's in a setuid situation and blocks calls that ask about user-specific things in the applescript. Am I going about this all wrong? I just want to run the equivalent of "sudo /usr/bin/osascript ..." Edit: FWIW, the first line that causes the "execution error" is: set userAppSupportPath to (POSIX path of (path to application support folder from user domain)) However, even with an empty script (on run argv, end run and that's it) I still get the 'gdut' message.

  • How to recalculate all-pairs shorthest paths on-line if nodes are getting removed?

    - by Pavel Shved
    Latest news about underground bombing made me curious about the following problem. Assume we have a weighted undirected graph, nodes of which are sometimes removed. The problem is to re-calculate shortest paths between all pairs of nodes fast after such removals. With a simple modification of Floyd-Warshall algorithm we can calculate shortest paths between all pairs. These paths may be stored in a table, where shortest[i][j] contains the index of the next node on the shortest path between i and j (or NULL value if there's no path). The algorithm requires O(n³) time to build the table, and eacho query shortest(i,j) takes O(1). Unfortunately, we should re-run this algorithm after each removal. The other alternative is to run graph search on each query. This way each removal takes zero time to update an auxiliary structure (because there's none), but each query takes O(E) time. What algorithm can be used to "balance" the query and update time for all-pairs shortest-paths problem when nodes of the graph are being removed?

  • IIS- defining a website as a dev site

    - by Lock
    I am new to IIS. Is there a way during the setup of IIS to have a variable of some sort set that I can use to tell my site that this is the development copy? I am using PHP via IIS 7.5 and would like to have a file with a few lines that define which databases etc is used by my application. Is this the purpose of web.config? I would love there to be a place in the setup of the website where I can set a few variables that are accessibly by my application. That way, when I migrate files to live, I don't need to worry about access details to databases etc.

  • Ember model is gone when I use the renderTemplate hook

    - by Mickael Caruso
    I have a single template - editPerson.hbs <form role="form"> FirstName: {{input type="text" value=model.firstName }} <br/> LastName: {{input type="text" value=model.lastName }} </form> I want to render this template when the user wants to edit an existing person or create a new person. So, I set up routes: App.Router.map(function(){ this.route("createPerson", { path: "/person/new" }); this.route("editPerson", { path: "/person/:id}); // other routes not show for brevity }); So, I define two routes - one for create and one for edit: App.CreatePersonRoute = Ember.Route.extend({ renderTemplate: function(){ this.render("editPerson", { controller: "editPerson" }); }, model: function(){ return {firstName: "John", lastName: "Smith" }; } }); App.EditPersonRoute = Ember.Route.extend({ model: function(id){ return {firstName: "John Existing", lastName: "Smith Existing" }; } }); So, I hard-code the models. I'm concerned about the createPerson route. I'm telling it to render the editPersonTemplate and to use the editPerson controller (which I don't show because I don't think it matters - but I made one, though.) When I use renderTemplate, I lose the model John Smith, which in turn, won't display on the editTemplate on the web page. Why? I "fixed" this by creating a separate and identical (to editPerson.hbs) createPerson.hbs, and removing the renderTemplate hook in the CreatePerson. It works as expected, but I find it somewhat troubling to have a separate and identical template for the edit and create cases. I looked everywhere for how to properly do this, and I found no answers.

  • Why does my IMultiBindingConverter get an array of strings when used to set TextBox.Text?

    - by mcohen75
    Hi- I'm trying to use a MultiBinding with a converter where the child elements also have a converter. The XAML looks like so: <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource localizedMessageConverter}" ConverterParameter="{x:Static res:Resources.RecordsFound}" > <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="ALIAS" Path="Alias" Mode="OneWay" /> <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="COUNT" Path="Count" Mode="OneWay" /> </MultiBinding> </TextBlock.Text> The problem I'm facing here is, whenever this is used with a TextBlock to specify the Text property, my IMultiValueConverter implementation gets an object collection of strings instead of the class returned by the IValueConverter. It seems that the ToString() method is called on the result of the inner converter and passed to the IMultiValueConverter. If used to specify the Content property of Label, all is well. It seems to me that the framework is assuming that the return type will be string, but why? I can see this for the MultiBinding since it should yield a result that is compatible with TextBlock.Text, but why would this also be the case for the Bindings inside a MultiBinding? If I remove the converter from the inner Binding elements, the native types are returned. In my case string and int.

  • WPF validation red border doesn't show If UserControl collapsed first

    - by Creepy Gnome
    There seems to be a bug with WPF in 3.5, and I was hoping someone may have found a workaround. Basically if you have a custom UserControl that contains a TextBox and it is in a Window but initialized to be Collapsed by default in the xaml or code behind if it fails validation when you make the control visible it will not show the red border until it fails while visible. However, this works correctly when visibility is set to Hidden, just no when Collapsed. I am already overriding the ErrorTemplate with a style to workaround the Adornment issue with the red border staying visibile when you collapse the control. Below is my full style for the TextBox. If there is any additional changes or additions to make it work correctly with collapsed controls that would be great. <Style TargetType="TextBox"> <Setter Property="Margin" Value="3" /> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <ControlTemplate.Resources> <BooleanToVisibilityConverter x:Key="converter" /> </ControlTemplate.Resources> <DockPanel LastChildFill="True"> <Border BorderThickness="2" BorderBrush="Red" Visibility="{ Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}" > <AdornedElementPlaceholder x:Name="placeholder" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true" > <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" /> </Trigger> </Style.Triggers> </Style>

  • Bug in CF9: values for unique struct keys referenced and overwritten by other keys.

    - by Gin Doe
    We've run into a serious issue with CF9 wherein values for certain struct keys can be referenced by other keys, despite those other keys never being set. See the following examples: Edit: Looks like it isn't just something our servers ate. This is Adobe bug-track ticket 81884: http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=81884. <cfset a = { AO = "foo" } /> <cfset b = { AO = "foo", B0 = "bar" } /> <cfoutput> The following should throw an error. Instead both keys refer to the same value. <br />Struct a: <cfdump var="#a#" /> <br />a.AO: #a.AO# <br />a.B0: #a.B0# <hr /> The following should show a struct with 2 distinct keys and values. Instead it contains a single key, "AO", with a value of "bar". <br />Struct b: <cfdump var="#b#" /> This is obviously a complete show-stopper for us. I'd be curious to know if anyone has encountered this or can reproduce this in their environment. For us, it happens 100% of the time on Apache/CF9 running on Linux, both RH4 and RH5. We're using the default JRun install on Java 1.6.0_14. To see the extent of the problem, we ran a quick loop to find other naming sequences that are affected and found hundreds of matches for 2 letter key names. A similar loop found more conflicts in 3 letter names. <cfoutput>Testing a range of affected key combinations. This found hundreds of cases on our platform. Aborting after 50 here.</cfoutput> <cfscript> teststring = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; stringlen = len(teststring); matchesfound = 0; matches = ""; for (i1 = 1; i1 <= stringlen; i1++) { symbol1 = mid(teststring, i1, 1); for (i2 = 1; i2 <= stringlen; i2++) { teststruct = structnew(); symbol2 = mid(teststring, i2, 1); symbolwhole = symbol1 & symbol2; teststruct[ symbolwhole ] = "a string"; for (q1 = 1; q1 <= stringlen; q1++) { innersymbol1 = mid(teststring, q1, 1); for (q2 = 1; q2 <= stringlen; q2++) { innersymbol2 = mid(teststring, q2, 1); innersymbolwhole = innersymbol1 & innersymbol2; if ((i1 != q1 || i2 != q2) && structkeyexists(teststruct, innersymbolwhole)) { // another affected pair of keys! writeoutput ("<br />#symbolwhole# = #innersymbolwhole#"); if (matchesfound++ > 50) { // we've seen enough abort; } } } } } } </cfscript> And edit again: This doesn't just affect struct keys but names in the variables scope as well. At least the variables scope has the presence of mind to throw an error, "can't load a null": <cfset test_b0 = "foo" /> <cfset test_ao = "bar" /> <cfoutput> test_b0: #test_b0# <br />test_ao: #test_ao# </cfoutput>

  • C# 4.0: casting dynamic to static

    - by Kevin Won
    This is an offshoot question that's related to another I asked here. I'm splitting it off because it's really a sub-question: I'm having difficulties casting an object of type dynamic to another (known) static type. I have an ironPython script that is doing this: import clr clr.AddReference("System") from System import * def GetBclUri(): return Uri("http://google.com") note that it's simply newing up a BCL System.Uri type and returning it. So I know the static type of the returned object. now over in C# land, I'm newing up the script hosting stuff and calling this getter to return the Uri object: dynamic uri = scriptEngine.GetBclUri(); System.Uri u = uri as System.Uri; // casts the dynamic to static fine Works no problem. I now can use the strongly typed Uri object as if it was originally instantiated statically. however.... Now I want to define my own C# class that will be newed up in dynamic-land just like I did with the Uri. My simple C# class: namespace Entity { public class TestPy // stupid simple test class of my own { public string DoSomething(string something) { return something; } } } Now in Python, new up an object of this type and return it: sys.path.append(r'C:..path here...') clr.AddReferenceToFile("entity.dll") import Entity.TestPy def GetTest(): return Entity.TestPy(); // the C# class then in C# call the getter: dynamic test = scriptEngine.GetTest(); Entity.TestPy t = test as Entity.TestPy; // t==null!!! here, the cast does not work. Note that the 'test' object (dynamic) is valid--I can call the DoSomething()--it just won't cast to the known static type string s = test.DoSomething("asdf"); // dynamic object works fine so I'm perplexed. the BCL type System.Uri will cast from a dynamic type to the correct static one, but my own type won't. There's obviously something I'm not getting about this...
