  • How to enable directory browsiing in IIS7?

    - by frankadelic
    How I enable directory browsing in IIS7? MS technet says this can be done in the IIS console: Open IIS Manager and navigate to the level you want to manage. In Features View, double-click Directory Browsing. In the Actions pane, click Enable if the Directory Browsing feature is disabled and you want to enable it. Or, click Disable if the Directory Browsing feature is enabled and you want to disable it. http://technet.microsoft.com/en-us/library/cc731109%28WS.10%29.aspx However, my IIS console doesn't have the Directory Browsing option mentioned in Step 2. How can this option be made available. Note, this is for a static HTML site, so I don't have any web.config or ASPX files.

  • XAttribute Generating strange namespaces

    - by Adam Driscoll
    I'm constructing an XElement with a couple attributes that have different namespaces. The code looks like this: var element = new XElement("SynchronousCommand", new XAttribute("{wcm}action", "add"), new XAttribute("{ns}id", Guid.NewGuid()), new XElement... ); The XML that is generated looks like this: <unattend xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:schemas-microsoft-com:unattend"> <SynchronousCommand d5p1:action="add" d5p2:id="c0f5fc6d-d407-4d3d-8a05-d84236cca2fb" xmlns:d5p2="ns" xmlns:d5p1="wcm"> ... </SynchronousCommand> </unattend> I'm just wondering if the auto-generated d5p2 is valid and why it is doing this. According to the XML standards here it seems like it would be valid. But why is it not: <unattend xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:schemas-microsoft-com:unattend"> <SynchronousCommand wcm:action="add" ns:id="c0f5fc6d-d407-4d3d-8a05-d84236cca2fb" > To generate the XML I'm doing this: public class unattend { public List<XElement> Any {get;} } var unattend = new unattend(); unattend.Add(element); serializer.Serialize(xmlWriter, unattend);

  • How do I reference my MainViewController from another class?

    - by todd412
    Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations: - (void)viewDidLoad { [super viewDidLoad]; cc = [CustomClass new]; NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"image-1-off.jpg"], [UIImage imageNamed:@"image-2-off.jpg"], [UIImage imageNamed:@"image-3-off.jpg"], [UIImage imageNamed:@"image-4-off.jpg"], nil]; offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; offSequence.animationImages = imageArray; offSequence.animationDuration = .8; offSequence.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:offSequence]; [offSequence startAnimating]; } That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line: [self.view addSubview:offSequence]; I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such: - (void) setMainViewController: (MainViewController *) the_mvc { mvc = the_mvc; } And then I called it within MainViewController like so: [cc setMainController:MainViewController:self]; But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?

  • Visual Studio - Edit source code located in a database

    - by mfeingold
    I am building something similar to Server Explorer for Apache CouchDB. One of the things necessary is to be able to edit CouchDB view definitions which in CouchDB are JavaScript functions. How can I trick Visual Studio into using my object to retrieve and save the content of the JavaScript function but still use the rest of it - I am happy with editor itself and have no intention of writing my own Editor/Language Service, etc. The latter would be much bigger effort than what this project warrants Edit After more digging I am still stuck. Here is what I know: IVsUIShellOpenDocument interface provides a method OpenStandardEditor which can be used to open the standard Visual Studio editor. As one of the parameters this method takes a Pointer to the IUnknown interface of the document data object. This object is supposed to implement several interfaces described in many places all over the MSDN. Visual Studio SDK also provides a 'sample' implementation of the document data object VsTextBufferClass. I can create an instance of this class and when I pass the pointer to the instance to the OpenStandardEditor I can see my editor and it seems to work ok. When I try to implement my own class implementing the same interfaces (IVsTextBuffer, VsTextBuffer, IVsTextLines) OpenStandardEditor method returns success, but VS bombs out on call editor.Show() with an access violation. My suspicion is that VsTextBufferClass also implements some other interface(s) but not in C# way but rather in the good old COM way. I just do not know which one(s). Any thoughts?

  • Java/JAXB: Accessing property of object in a list

    - by Mark Lewis
    Hello Using JAXB I've created a series of classes which represent my XML schema. Validating against the schema an XML file has thus become a 'tree' of java objects representing the XML. Now I'd like to access, delete and add an object of one the created types in my tree. If I've got classes' methods arranged like this: RootType class has: public List<FQType> getFq() { // and setter return fq; } FQType class has: public RemapType getRemap() { // and setter return remap; } RemapType class has: public String getSource() { // and setter return source; } What's the most concise way to code reading and writing of the 'source' member of a RemapType instance in an FQType instance with, say, fqtypeID=1, in an array of type RootType (in which RootType instances also each have rootID)? Currently I'm using a for loop Iterator in which is an if rootID = mySelectedRootID. In the if I nest a second for loop Iterator over the contained FQType instances and in that a second if fqTypeID = mySelectedFQTypeID. IE for loop iterator/if statement pairs to recognise the object of desire. With all the bells and whistles this way is nearly 15 lines of code to access a data type - can I do this in one line? Thanks

  • Why my object sees variables which were not given to it in the constructor?

    - by Roman
    I have the following code. Which is "correct" and which I do not understand: private static void updateGUI(final int i, final JLabel label) { SwingUtilities.invokeLater( new Runnable() { public void run() { label.setText("You have " + i + " seconds."); } } ); } I create a new instance of the Runnable class and then in the run method of this instance I use variables label and i. It works, but I do not understand why it work. Why the considered object sees values of these variables. According to my understanding the code should look like that (and its wrong): private static void updateGUI(final int i, final JLabel label) { SwingUtilities.invokeLater(new Runnable(i,label) { public Runnable(int i, JLabel label) { this.i = i; this.label = label; } public void run() { label.setText("You have " + i + " seconds."); } }); } So, I would give the i and label variables to the constructor so the object can access them... By the way, in the updateGUI I use final before the i and label. I think I used final because compiler wanted that. But I do not understand why.

  • Mount "Macrium Reflect" on a partition, boot from there?

    - by b e
    Can Macrium's Reflect recovery CD be mounted/used with GRUB ? If the cd can be 'put' (loaded/mounted/...) in a partition, then the only disc needed would be the actual recovery disc, which could be on an external hard drive, or even on the same machine in another partition, thus allowing on to recover using only what's on the machine itself. I have WXPpro and Xubuntu8.04 double mounted, really happy with them together, use each right now to fix problems with the other when they come up. Also have a partition for the Reflect CD, but I just can't get it to load from Grub, which would be great... Thanks for any thoughts, probably someone has already done this I know !

  • Advice needed: cold backup for SQL Server 2008 Express?

    - by Mikey Cee
    What are my options for achieving a cold backup server for SQL Server Express instance running a single database? I have an SQL Server 2008 Express instance in production that currently represents a single point of failure for my application. I have a second physical box sitting at the installation that is currently doing nothing. I want to somehow replicate my database in near real time (a little bit of data loss is acceptable) to the second box. The database is very small and resources are utilized very lightly. In the case that the production server dies, I would manually reconfigure my application to point to the backup server instead. Although Express doesn't support log shipping, I am thinking that I could manually script a poor man's version of it, where I use batch files to take the logs and copy them across the network and apply them to the second server at 5 minute intervals. Does anyone have any advice on whether this is technically achievable, or if there is a better way to do what I am trying to do? Note that I want to avoid having to pay for the full version of SQL Server and configure mirroring as I think it is an overkill for this application. I understand that other DB platforms may present suitable options (eg. a MySQL Cluster), but for the purposes of this discussion, let's assume we have to stick to SQL Server.

  • Render multiple Form instances

    - by vorpyg
    I have a simple application where users are supposed to bet on outcome of a match. A match consists of two teams, a result and a stake. Matches with teams are created in the Django admin, and participants are to fill in result and stake. The form must be generated dynamically, based on the matches in the database. My idea is to have one (Django) Form instance for each match and pass these instances to the template. It works fine when I do it from django shell, but the instances aren't rendered when I load my view. The form looks like this: class SuggestionForm(forms.Form): def __init__(self, *args, **kwargs): try: match = kwargs.pop('match') except KeyError: pass super(SuggestionForm, self).__init__(*args, **kwargs) label = match self.fields['result'] = forms.ChoiceField(label=label, required=True, choices=CHOICES, widget=forms.RadioSelect()) self.fields['stake'] = forms.IntegerField(label='', required=True, max_value=50, min_value=10, initial=10) My (preliminary) view looks like this: def suggestion_form(request): matches = Match.objects.all() form_collection = {} for match in matches: f = SuggestionForm(request.POST or None, match=match) form_collection['match_%s' % match.id] = f return render_to_response('app/suggestion_form.html', { 'forms': form_collection, }, context_instance = RequestContext(request) ) My initial thought was that I could pass the form_collection to the template and the loop throught the collection like this, but id does not work: {% for form in forms %} {% for field in form %} {{ field }} {% endfor %} {% endfor %} (The output is actually the dict keys with added spaces in between each letter - I've no idea why…) It works if I only pass one Form instance to the template and only runs the inner loop. Suggestions are greatly appreciated.

  • what's the difference between /etc/init.d/sshd start and /usr/sbin/sshd?

    - by jasono
    I'm having issues with passwordless ssh. I've checked, double checked and checked again that I have everything set up correctly. Both machines are RHEL6 and when the destination machine first boots up passwordless ssh does not work. If I stop ssh (service sshd stop or /ect/init.d/sshd stop) and then start it directly (/usr/sbin/sshd) passwordless ssh works fine. If I start ssh via the service (service sshd start or /etc/init.d/sshd start) passwordless ssh does not work. Just for testing I've tried commenting out the entire start() function in /etc/init.d/sshd and replace it with /usr/sbin/sshd - that still fails to allow passwordless ssh. I believe that this means that something in the /etc/init.d/sshd file is causing the screw up but I don't know enough about linux to narrow the issue down.

  • Connecting to a DLNA server in Vista's Media Centre

    - by Basic
    I've got a Windows 7 machine with a DLNA server set up. I can stream from it to my mobile and a number of other devices with no issues. All clients are auto-authorised so no permissions issues either. I have a Vista laptop on the network which I'd like to use to play back some of the videos. I can see the media server in the network view, if I double-click it, I can see the server in Windows Media Player. I can't find any way to add a DLNA source to Windows Media Centre, though. Where's the setting hidden?

  • Non-english domain naming issues in programming

    - by Svend
    Most programming code, I imagine is written in english. But I'm curious how people handling the issue of naming herein. Alot of programming is done within some bussiness domain, usually with well established terms for certain procedures, items. I'm from Denmark for instance, and something I work alot with has a term called "indblikskode", which sorta translates to "insight code". So, do I use the line "string indblikskode = ..." in the C# code for some webservice related to this? Or do I try to use a translation, such as "insightcode"? The bussiness I'm in isn't even consistent in it's language, for instance using the term "organisatorisk enhed" (organizatorical unit), but just as often using the abbreviation "OU", which is obviously abbreviated from the english. How do other people handle this naming issue, while keeping consistent, and sane (in everything from simple variable names in your code, to database tables, to server names)? Duplicates: Should identifiers and comments be always in English or in the native language of the application and developers? Do you use another language instead of english ?

  • How to dual OS 32-bit/64-bit Windows 7 Ultimate.

    - by Cyril Horad
    I have a problem with regards to my nVidia driver not running on 64-bit. I decided to install both 32-bit and 64-bit on my ASUS K42JC (4GB RAM upgrade) in order to function the nVidia on the 32-bit. My question is, how could I make my laptop run on either 32-bit or 64-bit OS. What options I am suppose to use, a single, double, or triple partition? From an answer: Well. When I installed the nVidia driver from either the ASUS site and the prescribed driver from NVIDA site via System Requirements Lab, both ended up freezing my laptop to the point when the desktop is about the finish booting. I have tried three(3) times reformatting and trying to fix the problem. Yet no use. I filed a ticket to the Asus support but for now no replies yet. But this bothers me, why wouldn't the nVidia run on 64bit yet it runs perfectly on 32bit.

  • Is there a default way to get hold of an internal property in jQueryUi widget?

    - by prodigitalson
    Im using an existing widget from the jquery-ui labs call selectmenu. It has callback options for the events close and open. The problem is i need in these event to animate a node that is part of the widget but not what its connected to. In order to do this i need access to this node. for example if i were to actually modify the widget code itself: // ... other methods/properties "open" : function(event){ // ... the original logic // this is my animation $(this.list).slideUp('slow'); // this is the orginal call to _trigger this._trigger('open', event, $this._uiHash()); }, // ... other methods/properties However when in the scope of the event handler i attach this is the orginal element i called the widget on. I need the widget instance or specifically the widget instance's list property. $('select#custom').selectmenu({ 'open': function(){ // in this scope `this` is an HTMLSelectElement not the ui widget } }); Whats the best way to go about getting the list property from the widget?

  • RAID 1 not performing as expected

    - by Faken
    I recently bought a new 320Gb hard drive for my computer to set up RAID 1 on it for some added security. Installation went as smooth as could possibly be (plug in power, plug in data cable, start up computer, Intel software recognized new drive, right click create RAID 1, done!). However, for some inexplicable reason, I seem to have strange test results when using BENCH32. On my old configuration, a single 7200 rpm drive, I achieved about 60 MB/s write and 70 MB/s read. With a new RAID 1 configuration, I would expect the write to be slightly diminished but read to be significantly improved (though not exactly double speed). However, with the new configuration, I am getting 90 MB/s write and only about 80 MB/s read. I should NOT be getting improved write performance, especially NOT better than read! What's going on? My system setup is: q6600 2.4ghz CPU 4Gb DDR2 667mhz RAM on board Intel ICH9R "RAID chip" 2x Seagate 7200 RPM 320GB drives in RAID 1 Widows 7 home premium 64-bit

  • FileReference.save() duplicates ByteArray

    - by bartekb
    Hi, I've encountered a memory problem using FileReference.save(). My Flash application generates of a lot of data in real-time and needs to save this data to a local file. As I understand, Flash 10 (as opposed to AIR) does not support streaming to a file. But, what's even worse is that FileReference.save() duplicates all the data before saving it. I was looking for a workaround to this doubled memory usage and thought about the following approach: What if I pass a custom subclass of ByteArray as an argument to FileReference.save(), where this ByteArray subclass would override all read*() methods. The overridden read*() methods would wait for a piece of data to be generated by my application, return this piece of data and immediately remove it from the memory. I know how much data will be generated, so I could also override length/bytesAvailable methods. Would it be possible? Could you give me some hint how to do it? I've created a subclass of ByteArray, registered an alias for it, passed an instance of this subclass to FileReference.save(), but somehow FileReference.save() seems to treat it just as it was a ByteArray instance and doesn't call any of my overridden methods... Thanks a lot for any help!

  • Comparing all properties of an object using expression trees

    - by stringargs
    Hi, I'm trying to write a simple generator that uses an expression tree to dynamically generate a method that compares all properties of an instance of a type to the properties of another instance of that type. This works fine for most properties, like int an string, but fails for DateTime? (and presumably other nullable value types). The method: static Delegate GenerateComparer(Type type) { var left = Expression.Parameter(type, "left"); var right = Expression.Parameter(type, "right"); Expression result = null; foreach (var p in type.GetProperties()) { var leftProperty = Expression.Property(left, p.Name); var rightProperty = Expression.Property(right, p.Name); var equals = p.PropertyType.GetMethod("Equals", new[] { p.PropertyType }); var callEqualsOnLeft = Expression.Call(leftProperty, equals, rightProperty); result = result != null ? (Expression)Expression.And(result, callEqualsOnLeft) : (Expression)callEqualsOnLeft; } var method = Expression.Lambda(result, left, right).Compile(); return method; } On a DateTime? property it fails with: Expression of type 'System.Nullable`1[System.DateTime]' cannot be used for parameter of type 'System.Object' of method 'Boolean Equals(System.Object)' OK, so it finds an overload of Equals that expects object. So why can't I pass a DateTime? into that, as it's convertible to object? If I look at Nullable<T>, it indeed has an override of Equals(object o). PS: I realize that this isn't a proper generator yet as it can't deal with null values, but I'll get to that :)

  • JavaApplicationStub Compatibility with all java versions

    - by neelamsharma
    Hi, I am running a Java application on Mac Leopard & on Mac Mini. My Mac Mini upgraded, it is using Java Version 1.6.0_17 and Mac Leopard have version 1.5.0_13. To run that application on Mac Mini I have to copy JavaApplicationStub from path -"/System/Library/Frameworks/JavaVM.framework/Resources/MacOS/JavaApplicationStub" to my application "Content/Resources/Java". But this application successfully run on Mac Leopard. If I do not copy stub at Mac Mini then I am unable to launch application using app by double click, it shows icon for few second then disappears, so in that case I have to run application with its jar. I want that without copying explicitly JavaApplicationStub, how can I run app with all versions of java. If this possible then what changes I have to made? The info.plist file contain JVMVersion is 1.4+. Thanks!

  • ffmpeg volume parameter format

    ffmpeg's -vol parameter is confusing me. 256 => normal (i guess meaning same as input volume, no change) 512 => (double the volume - read this somewhere). So what to do for 3 times the volume? 1.5 times the volume? Basically, lets say I have the max sound amplitudes (audacity levels) in 3 files as: 0.8 0.6 0.9 I want to amplify in the first two files, so that max=0.9 in all files. What parameters of -vol I would use?

  • Type-safe mapping from Class<T> to Thing<T>

    - by Joonas Pulakka
    I want to make a map-kind of container that has the following interface: public <T> Thing<T> get(Class<T> clazz); public <T> void put(Class<T> clazz, Thing<T> thing); The interesting point is that the Ts in each Class<T><- Thing<T> pair is the same T, but the container should be able to hold many different types of pairs. Initially I tried a (Hash)Map. But, for instance, Map<Class<T>, Thing<T>> is not right, because then T would be same T for all pairs in that map. Of course, Map<Class<?>, Thing<?>> works, but then I don't have type-safety guarantees so that when I get(String.class), I can't be sure that I get a Thing<String> instance back. Is there a way to accomplish the kind of type safety that I'm looking for?

  • Ruby TypeErrors involving `expected Data`

    I've ran into situations where I have gotten these expected Data errors before, but they have always pointed to ActiveRecord not playing well with other libraries in the past. This piece of code: def load(kv_block, debug=false) # Converts a string block to a Hash using split kv_map = StringUtils.kv_array_to_hash(kv_block) # Loop through each key, value kv_map.each do |mem,val| # Format the member from camel case to underscore member = mem.camel_to_underscore() # If the object includes a method to set the key (i.e. the key # is a member of self), invoke the method, setting the value of # the member) if self.methods.include?(member.to_set_method_name()) then # Exception thrown here self.send(member.to_set_method_name(), val) # Else, check for the same case, this time for an instance variable elsif self.instance_variable_defined?(member.to_instance_var_name()) self.instance_variable_set(member.to_instance_var_name(), val) # Else, complain that the object doesn't understand the key with # respect to its class definition. else raise ArgumentError, "I don't know what to do with #{member}. #{self.class} does not have a member or function called #{member}" end end end produces the error wrong argument type #<Class:0x11a02088> (expected Data) (TypeError) in the each loop on the first if test. I've inspected a post-mortem debugging instance using rdebug, and running that line manually, it works without a hitch. Has anyone seen this error before and what's been your solution to it? I used to think it was ActiveRecord and other gems stomping on each other's definitions, but I removed any references to ActiveRecord and this still occurs.

  • Manually start screensaver with password protect

    - by gibberish
    Windows 7 I wish to manually lock the computer so I placed a shortcut to scrnsave.exe on the desktop. (I do not want the user to use Ctrl+Alt+Del -- Lock This Computer for various reasons) Problem is that when double-clicked, the screen saver starts but it's not password protected. However, in Personalization -- Screen Saver, that same screen saver is the selected one and it IS configured to display logon screen upon resume. And that works when Windows starts the screen saver.
