• Static Libraries on iPhone device

  - by Akusete

  I have two projects, a Cocoa iPhone application and a static library which it uses. I've tested it successfully on the iPhone simulator, but when I try to deploy it to my iPhone device I get (symbol not found) link errors. If I remove the dependancy of the library the project builds/runs fine. I have made sure all the build settings are set to iPhoneOS not the simulator. Im sure its something simple, but has anyone run into similar problems moving from iPhone simulator to device? --EDIT: I have managed to create new projects (one for the application and one for the static library), and successfully get them to run on the iPhone or simulator. But I have a very strange problem... for each specific project I cannot get it working for BOTH the device and the simulator... I have double checked the build settings, made sure the libraries that are being references are for the matching build settings (I believe) but I cannot resolve these linking errors. I think I must be doing something very wrong... all the apple documentation says 'its super simple - one click' but this is giving me a lot of problems. This is probably something to do with xCode build settings, but I cannot seem to understand why selecting the different build platforms and rebuilding the libraries does not work.

• Use Django ORM as standalone [closed]

  - by KeyboardInterrupt

  Possible Duplicates: Use only some parts of Django? Using only the DB part of Django I want to use the Django ORM as standalone. Despite an hour of searching Google, I'm still left with several questions: Does it require me to set up my Python project with a setting.py, /myApp/ directory, and modules.py file? Can I create a new models.py and run syncdb to have it automatically setup the tables and relationships or can I only use models from existing Django projects? There seems to be a lot of questions regarding PYTHONPATH. If you're not calling existing models is this needed? I guess the easiest thing would be for someone to just post a basic template or walkthrough of the process, clarifying the organization of the files e.g.: db/ __init__.py settings.py myScript.py orm/ __init__.py models.py And the basic essentials: # settings.py from django.conf import settings settings.configure( DATABASE_ENGINE = "postgresql_psycopg2", DATABASE_HOST = "localhost", DATABASE_NAME = "dbName", DATABASE_USER = "user", DATABASE_PASSWORD = "pass", DATABASE_PORT = "5432" ) # orm/models.py # ... # myScript.py # import models.. And whether you need to run something like: django-admin.py inspectdb ... (Oh, I'm running Windows if that changes anything regarding command-line arguments.).

• XmlDocument.Load() throws XmlSchemaValidationException

  - by Praetorian

  Hi, I'm trying to validate an XML document against a schema (which is embedded in my program as a resource). I got everything to work, so I tried to test for errors by adding a second sibling node in the XML at a location where the schema specifies maxOccurs="1". The problem is that my ValidationEventHandler is never getting called, also XmlDocument.Load() is throwing an XmlSchemaValidationException exception when I'd expected XmlDocument.Validate() to do that. This is the code I have: private void ValidateUserData( string xmlPath ) { var resInfo = Application.GetResourceStream( new Uri( @"MySchema.xsd", UriKind.Relative ) ); var schema = XmlSchema.Read( resInfo.Stream, SchemaValidationCallBack ); XmlSchemaSet schemaSet = new XmlSchemaSet(); schemaSet.Add( schema ); schemaSet.ValidationEventHandler += SchemaValidationCallBack; XmlReaderSettings settings = new XmlReaderSettings(); settings.Schemas = schemaSet; settings.ValidationType = ValidationType.Schema; XmlDocument doc = new XmlDocument(); using( XmlReader reader = XmlReader.Create( xmlPath, settings ) ) { doc.Load( reader ); // <-- This line throws an exception if XML is ill-formed reader.Close(); } doc.Validate( SchemaValidationCallBack );// <-- This is never reached } private void SchemaValidationCallBack( object sender, ValidationEventArgs e ) { Console.WriteLine( "SchemaValidationCallBack: " + e.Message ); } How do I get the callback to be called so I can handle validation errors? Thanks for your help!

• Saving animated GIFs using urllib.urlopen (image saved does not animate)

  - by wenbert

  I have Apache2 + Django + X-sendfile. My problem is that when I upload an animated GIF, it won't "animate" when I output through the browser. Here is my code to display the image located outside the public accessible directory. def raw(request,uuid): target = str(uuid).split('.')[:-1][0] image = Uploads.objects.get(uuid=target) path = image.path filepath = os.path.join(path,"%s.%s" % (image.uuid,image.ext)) response = HttpResponse(mimetype=mimetypes.guess_type(filepath)) response['Content-Disposition']='filename="%s"'\ %smart_str(image.filename) response["X-Sendfile"] = filepath response['Content-length'] = os.stat(filepath).st_size return response UPDATE It turns out that it works. My problem is when I try to upload an image via URL. It probably doesn't save the entire GIF? def handle_url_file(request): """ Open a file from a URL. Split the file to get the filename and extension. Generate a random uuid using rand1() Then save the file. Return the UUID when successful. """ try: file = urllib.urlopen(request.POST['url']) randname = rand1(settings.RANDOM_ID_LENGTH) newfilename = request.POST['url'].split('/')[-1] ext = str(newfilename.split('.')[-1]).lower() im = cStringIO.StringIO(file.read()) # constructs a StringIO holding the image img = Image.open(im) filehash = checkhash(im) image = Uploads.objects.get(filehash=filehash) uuid = image.uuid return "%s" % (uuid) except Uploads.DoesNotExist: img.save(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext)))) del img filesize = os.stat(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext)))).st_size upload = Uploads( ip = request.META['REMOTE_ADDR'], filename = newfilename, uuid = randname, ext = ext, path = settings.UPLOAD_DIRECTORY, views = 1, bandwidth = filesize, source = request.POST['url'], size = filesize, filehash = filehash, ) upload.save() #return uuid return "%s" % (upload.uuid) except IOError, e: raise e Any ideas?

• You are only allowed to have a single MapView in a MapActivity

  - by ProNeticas

  I have a function that shows a map page so I can get the user to choose their current location. But if you run this function twice it crashes the App with the Single MapView in a MapActivity error (i.e. opening that settings view again). public void showMapSetterPage(View v) { Log.i(DEBUG_TAG, "Settings screen, set map center launched"); // Set which view object we fired off from set_pv(v); // Show Map Settings Screen setContentView(R.layout.set_map_center); // Initiate the center point map if (mapView == null) { mapView = (MapView) findViewById(R.id.mapview); } mapView.setLongClickable(true); mapView.setStreetView(true); mapView.setBuiltInZoomControls(false); mapView.setSatellite(false); mapController = mapView.getController(); mapController.setZoom(18); LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Location location = lm .getLastKnownLocation(LocationManager.GPS_PROVIDER); int lat = (int) (location.getLatitude() * 1E6); int lng = (int) (location.getLongitude() * 1E6); Log.i(DEBUG_TAG, "The LAT and LONG is: " + lat + " == " + lng); point = new GeoPoint(lat, lng); // mapController.setCenter(point); mapController.animateTo(point); } So I have a button that shows this View and onClick="showMapSetterPage". But if you go back to the settings screen out of the map and click the button again I get this error: 03-06 20:55:54.091: ERROR/AndroidRuntime(28014): Caused by: java.lang.IllegalStateException: You are only allowed to have a single MapView in a MapActivity How can I delete the MapView and recreate it?

• How to change CSS color values in real-time off a javascript slider?

  - by bflora

  I'm making a page where the user gets a javascript slider that goes from 0 to 100 and can use it to set the opacity of a div on the page. I want the opacity of that div to change in real-time as they work the slider. I've not done this before. What's the best approach? There cursor in the slider displays the slider's current value as you move it. It seems to be that I just need to find a way to display that value in any arbitrary other place on the page so I can display it in the style settings for the div. The .js file that generates the slider has a line that (I think) is setting the current value in the cursor: $(this).children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); TO get this changing number to display somewhere else at the same time, do I just need to add a div somewhere and then add a line like this? $("#newDivId").children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); That seems like it would give me the number showing up in a div. How then would I get it into a form I could put into the style settings for a div? If this was a php variable, I would do something like this, style="opacity:<?php print $value ?>;" What would be the .js equivalent?

• How do I save the edits for a checkbox that implements an email notification?

  - by Ralph The Mouf

  On my site, a user gets email notifications when someone comments on their profile, or comments on their blog etc...I have made a email settings page that has checkboxes to allow the user to decide to receive emails or not. This is what I am wrapping around the email notification code chunck for the pages that have the php mail: <?php if(isset($_POST['email_toggle']) && $_POST['email_toggle'] == 'true') { if(isset($_POST['commentProfileSubmit']) && $auth) { $query etc $to = etc } } My question is what do I put on the email settings script that has the actual check boxes to make them stay checked or unchecked once you submit your settings? Another words what do I put in the if(isset portion to implement the changes? if(isset($_POST['email_toggle']) && $_POST['email_toggle'] == 'true') { /* what do I put here? */ header("Location: Profile.php?id=" . $auth->id); mysql_query($query,$connection); /* input/check boxes and submit button */ <tr> <td class="email_check"> <input type="checkbox" name="email_toggle" value="true" checked="checked" /> Receive email Notifications When Someone Answers A Question You've Answered </td> </tr> <tr> <td> <input style="margin:10px 0px 0px 10px;" class="submit" type="submit" name="email_toggle" value="Save Settings" /> </td> </tr> }

• How to setup and teardown temporary django db for unit testing?

  - by blokeley

  I would like to have a python module containing some unit tests that I can pass to hg bisect --command. The unit tests are testing some functionality of a django app, but I don't think I can use hg bisect --command manage.py test mytestapp because mytestapp would have to be enabled in settings.py, and the edits to settings.py would be clobbered when hg bisect updates the working directory. Therefore, I would like to know if something like the following is the best way to go: import functools, os, sys, unittest sys.path.append(path_to_myproject) os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings' def with_test_db(func): """Decorator to setup and teardown test db.""" @functools.wraps def wrapper(*args, **kwargs): try: # Set up temporary django db func(*args, **kwargs) finally: # Tear down temporary django db class TestCase(unittest.TestCase): @with_test_db def test(self): # Do some tests using the temporary django db self.fail('Mark this revision as bad.') if '__main__' == __name__: unittest.main() I should be most grateful if you could advise either: If there is a simpler way, perhaps subclassing django.test.TestCase but not editing settings.py or, if not; What the lines above that say "Set up temporary django db" and "Tear down temporary django db" should be?

• Waiting until one event has happened before moving onto the next.

  - by jaasum

  I currently have a scrolling anchor animation that also adds an "active" class to the anchor clicked. I am trying to fit the below function into the works as well, so say someone clicks "anchor 1", "anchor 1" will get an active class and the window will scroll to that location. But, after that has happened say the user manually begins scrolling down the page, I want the active class to be removed. The problem I am running up against now is that the below function will happen when the scrolling animation from a clicked anchor is taking place. How can I disable this only when the window is being scrolled from a clicked anchor? $(window).scroll(function() { $('a[href^=#]').removeClass('active'); }); Here is the scrolling anchor script I am working with. /******* *** Anchor Slider by Cedric Dugas *** *** Http://www.position-absolute.com *** Never have an anchor jumping your content, slide it. Don't forget to put an id to your anchor ! You can use and modify this script for any project you want, but please leave this comment as credit. *****/ jQuery.fn.anchorAnimate = function(settings) { settings = jQuery.extend({ speed : 500 }, settings); return this.each(function(){ var caller = this $(caller).click(function (event) { event.preventDefault() var locationHref = window.location.href var elementClick = $(caller).attr("href") var destination = $(elementClick).offset().top; $("html:not(:animated),body:not(:animated)").animate({ scrollTop: destination}, settings.speed, 'easeOutCubic', function() { window.location.hash = elementClick }); return false; }) }) } And lastly, my jQuery // Scrolling Anchors $('[href^=#]').anchorAnimate(); // Active Class For Clicked Anchors var anchorscroll = $('a[href^=#]') anchorscroll.click(function(){ var anchorlocation = $(this).attr("href"); anchorscroll.removeClass('active'); $(this).addClass('active'); $('a[href='+anchorlocation+']').addClass('active'); });

• Programmatically setup a PEAP connection in Windows Mobile

  - by tomlog

  I have been working on this for a few days and this is doing my head in: Our application is built using the .NET Compact Framework 2.0 and running on Windows Mobile 5 & 6 devices. We can set the WLAN connection of the device programmatically using the Wireless Zero Config functions (described here: msdn.microsoft.com/en-us/library/ms894771.aspx), most notably the WZCSetInterface function which we pinvoke from our application. This works fine for WEP and WPA-PSK connections. In a recent effort to add support for WPA2 networks we decided to modify the code. We have successfully added support for WPA2 which uses a certificate for the 802.1x authentication by setting the correct registry settings before calling WZCSetInterface. Now we want to do the same for WPA2 using PEAP (MS-CHAPv2) authentication. When manually creating such a connection in Windows Mobile the user will be prompted to enter the domain/user/password details. In our application we will have those details stored locally and want to do this all programmatically without any user intervention. So I thought going along the same route as the certificate authentication, setting the correct registry entries before calling WZCSetInterface. The registry settings we set are: \HKCU\Comm\EAP\Config\[ssid name] Enable8021x = 1 (DWORD) LastAuthSuccessful = 1 (DWORD) EapTypeId = 25 (DWORD) Identity = "domain\username" (string) Password = binary blob containing the password that is encrypted using the CryptProtectData function (described here: msdn.microsoft.com/en-us/library/ms938309.aspx) But when these settings are set and I call WZCSetInterface with the correct parameters, it still prompts me with the User Logon dialog asking for the domain/username/password. Has anyone got an idea what I need to do to prevent the password dialog from appearing and connect straight away with the settings stored in the registry?

• Declaring models elsewhere than in "models.py" AND dynamically

  - by sebpiq

  Hi ! I have an application that splits models into different files. Actually the folder looks like : >myapp __init__.py models.py >hooks ... ... myapp don't care about what's in the hooks, folder, except that there are models, and that they have to be declared somehow. So, I put this in myapp.__init__.py : from django.conf import settings for hook in settings.HOOKS : try : __import__(hook) except ImportError as e : print "Got import err !", e #where settings.HOOKS = ("myapp.hooks.a_super_hook1", ...) The problem is that it doesn't work when I run syncdb(and throws some strange "Got import err !"... strange considering that it's related to another module of my program that I don't even import anywhere :/ ) ! So I tried successively : 1) for hook in settings.HOOKS : try : exec ("from %s import *" % hook) - doesn't work either : syncdb doesn't install the models in hooks 2) from myapp.hooks.a_super_hook1 import * - This works 3) exec("from myapp.hooks.a_super_hook1 import *") - This works to So I checked that in the test 1), the statement executed is the same than in tests 2) and 3), and it is exactly the same ... Any idea ???

• Android: stop activity appearing when an app is reopened?

  - by AP257

  Hi there In Android, I have some code to check whether the user has GPS switched on, and launch the Settings for them to turn it on if they don't. It looks like this: private void buildAlertMessageNoGps() { final AlertDialog.Builder builder = new AlertDialog.Builder(this); builder .setMessage( "Your GPS seems to be disabled - you need it to get a location fix. Turn it on now?") .setCancelable(false).setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick( @SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) { Intent j = new Intent(); j.setAction("android.settings.LOCATION_SOURCE_SETTINGS"); startActivity(j); } }).setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) { dialog.cancel(); } }); final AlertDialog alert = builder.create(); alert.show(); } However, I'm finding that if the user opens the Settings, turns GPS on, then carries on using the app as normal, there is an odd problem. Often, when the user reopens the app, the Settings are at the front. How can I set them so they don't keep reappearing? I wonder if I should be using the CLEAR_TOP flag or something similar... I've tried looking at the docs for the Activity flags but find them a bit confusing. Anyone know?

• Split user.config into different files for faster saving (at runtime)

  - by HorstWalter

  In my c# Windows Forms application (.net 3.5 / VS 2008) I have 3 settings files resulting in one user.config file. One setting file consists of larger data, but is rarely changed. The frequently changed data are very few. However, since the saving of the settings is always writing the whole (XML) file it is always "slow". SettingsSmall.Default.Save(); // slow, even if SettingsSmall consists of little data Could I configure the settings somehow to result in two files, resulting in: SettingsSmall.Default.Save(); // should be fast SettingsBig.Default.Save(); // could be slow, is seldom saved I have seen that I can use the SecionInformation class for further customizing, however what would be the easiest approach for me? Is this possible by just changing the app.config (config.sections)? --- added information about App.config The reason why I get one file might be the configSections in the App.config. This is how it looks: <configSections <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" <section name="XY.A.Properties.Settings2Class" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" / <section name="XY.A.Properties.Settings3Class" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" / </sectionGroup </configSections I got the sections when I've added the 2nd and 3rd settings file. I have not paid any attention to this, so it was somehow the default of VS 2008. The single user.config has these 3 sections, it is absolutely transparent. Only I do not know how to tell the App.config to create three independent files instead of one. I have "played around" with the app.config above, but e.g. when I remove the config sections my applications terminates with an exception.

• Generic Func<> as parameter to base method

  - by WestDiscGolf

  I might be losing the plot, but I hope someone can point me in the right direction. What am I trying to do? I'm trying to write some base methods which take Func< and Action so that these methods handle all of the exception handling etc. so its not repeated all over the place but allow the derived classes to specify what actions it wants to execute. So far this is the base class. public abstract class ServiceBase<T> { protected T Settings { get; set; } protected ServiceBase(T setting) { Settings = setting; } public void ExecAction(Action action) { try { action(); } catch (Exception exception) { throw new Exception(exception.Message); } } public TResult ExecFunc<T1, T2, T3, TResult>(Func<T1, T2, T3, TResult> function) { try { /* what goes here?! */ } catch (Exception exception) { throw new Exception(exception.Message); } } } I want to execute an Action in the following way in the derived class (this seems to work): public void Delete(string application, string key) { ExecAction(() => Settings.Delete(application, key)); } And I want to execute a Func in a similar way in the derived class but for the life of me I can't seem to workout what to put in the base class. I want to be able to call it in the following way (if possible): public object Get(string application, string key, int? expiration) { return ExecFunc(() => Settings.Get(application, key, expiration)); } Am I thinking too crazy or is this possible? Thanks in advance for all the help.

  First off I'd like to let everyone know I have searched my particular problem and can't seem to find what's causing my problem. I have an SQL Server 2008 instance running on a network machine and a client I have written connecting to it. To connect I have a small segment of code that establishes a connection to an sql server 2008 instance and returns a DataTable populated with the results of whatever query I run against the server, all pretty standard stuff really. Anyway the issue is, whenever I open my program and call this method, upon the first call to my method, regardless as to what I've set my Connection Timeout value as in the connection string, it takes about 15 seconds and then times out. Bizarrely though the second or third call I make to the method will work without a problem. I have opened up the ports for SQL Server on the server machine as outlined in this article: How to Open firewall ports for SQL Server and verified that it is correctly configured. Can anyone see a particular problem in my code? string _connectionString = "Server=" + @Properties.Settings.Default.sqlServer + "; Initial Catalog=" + @Properties.Settings.Default.sqlInitialCatalog + ";User Id=" + @Properties.Settings.Default.sqlUsername + ";Password=" + @Properties.Settings.Default.sqlPassword + "; Connection Timeout=1"; private DataTable ExecuteSqlStatement(string command) { using (SqlConnection conn = new SqlConnection(_connectionString)) { try { conn.Open(); using (SqlDataAdapter adaptor = new SqlDataAdapter(command, conn)) { DataTable table = new DataTable(); adaptor.Fill(table); return table; } } catch (SqlException e) { throw e; } } } The SqlException that is caught at my catch is : "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." This occurs at the conn.Open(); line in the code snippet I have included. If anyone has any ideas that'd be great!

• Error on 64 Bit Install of IIS &ndash; LoadLibraryEx failed on aspnet_filter.dll

  - by Rick Strahl

  I’ve been having a few problems with my Windows 7 install and trying to get IIS applications to run properly in 64 bit. After installing IIS and creating virtual directories for several of my applications and firing them up I was left with the following error message from IIS: Calling LoadLibraryEx on ISAPI filter “c:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll” failed This is on Windows 7 64 bit and running on an ASP.NET 4.0 Application configured for running 64 bit (32 bit disabled). It’s also on what is essentially a brand new installation of IIS and Windows 7. So it failed right out of the box. The problem here is that IIS is trying to loading this ISAPI filter from the 32 bit folder – it should be loading from Framework64 folder note the Framework folder. The aspnet_filter.dll component is a small Win32 ISAPI filter used to back up the cookieless session state for ASP.NET on IIS 7 applications. It’s not terribly important because of this focus, but it’s a default loaded component. After a lot of fiddling I ended up with two solutions (with the help and support of some Twitter folks): Switch IIS to run in 32 bit mode Fix the filter listing in ApplicationHost.config Switching IIS to allow 32 Bit Code This is a quick fix for the problem above which enables 32 bit code in the Application Pool. The problem above is that IIS is trying to load a 32 bit ISAPI filter and enabling 32 bit code gets you around this problem. To configure your Application Pool, open the Application Pool in IIS Manager bring up Advanced Options and Enable 32 Bit Applications: And voila the error message above goes away. Fix Filters Enabling 32 bit code is a quick fix solution to this problem, but not an ideal one. If you’re running a pure .NET application that doesn’t need to do COM or pInvoke Interop with 32 bit apps there’s usually no need for enabling 32 bit code in an Application Pool as you can run in native 64 bit code. So trying to get 64 bit working natively is a pretty key feature in my opinion :-) So what’s the problem – why is IIS trying to load a 32 bit DLL in a 64 bit install, especially if the application pool is configured to not allow 32 bit code at all? The problem lies in the server configuration and the fact that 32 bit and 64 bit configuration settings exist side by side in IIS. If I open my Default Web Site (or any other root Web Site) and go to the ISAPI filter list here’s what I see: Notice that there are 3 entries for ASP.NET 4.0 in this list. Only two of them however are specifically scoped to the specifically to 32 bit or 64 bit. As you can see the 64 bit filter correctly points at the Framework64 folder to load the dll, while both the 32 bit and the ‘generic’ entry point at the plain Framework 32 bit folder. Aha! Hence lies our problem. You can edit ApplicationHost.config manually, but I ran into the nasty issue of not being able to easily edit that file with the 32 bit editor (who ever thought that was a good idea???? WTF). You have to open ApplicationHost.Config in a 64 bit native text editor – which Visual Studio is not. Or my favorite editor: EditPad Pro. Since I don’t have a native 64 bit editor handy Notepad was my only choice. Or as an alternative you can use the IIS 7.5 Configuration Editor which lets you interactively browse and edit most ApplicationHost settings. You can drill into the configuration hierarchy visually to find your keys and edit attributes and sub values in property editor type interface. I had no idea this tool existed prior to today and it’s pretty cool as it gives you some visual clues to options available – especially in absence of an Intellisense scheme you’d get in Visual Studio (which doesn’t work). To use the Configuration Editor go the Web Site root and use the Configuration Editor option in the Management Group. Drill into System.webServer/isapiFilters and then click on the Collection’s … button on the right. You should now see a display like this: which shows all the same attributes you’d see in ApplicationHost.config (cool!). These entries correspond to these raw ApplicationHost.config entries: <filter name="ASP.Net_4.0" path="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" enableCache="true" preCondition="runtimeVersionv4.0" /> <filter name="ASP.Net_4.0_64bit" path="C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_filter.dll" enableCache="true" preCondition="runtimeVersionv4.0,bitness64" /> <filter name="ASP.Net_4.0_32bit" path="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" enableCache="true" preCondition="runtimeVersionv4.0,bitness32" /> The key attribute we’re concerned with here is the preCondition and the bitness subvalue. Notice that the ‘generic’ version – which comes first in the filter list – has no bitness assigned to it, so it defaults to 32 bit and the 32 bit dll path. And this is where our problem comes from. The simple solution to fix the startup problem is to remove the generic entry from this list here or in the filters list shown earlier and leave only the bitness specific versions active. The preCondition attribute acts as a filter and as you can see here it filters the list by runtime version and bitness value. This is something to keep an eye out in general – if a bitness values are missing it’s easy to run into conflicts like this with any settings that are global and especially those that load modules and handlers and other executable code. On 64 bit systems it’s a good idea to explicitly set the bitness of all entries or remove the non-specific versions and add bit specific entries. So how did this get misconfigured? I installed IIS before everything else was installed on this machine and then went ahead and installed Visual Studio. I suspect the Visual Studio install munged this up as I never saw a similar problem on my live server where everything just worked right out of the box. In searching about this problem a lot of solutions pointed at using aspnet_regiis –r from the Framework64 directory, but that did not fix this extra entry in the filters list – it adds the required 32 bit and 64 bit entries, but it doesn’t remove the errand un-bitness set entry. Hopefully this post will help out anybody who runs into a similar situation without having to trouble shoot all the way down into the configuration settings and noticing the bitness settings. It’s a good lesson learned for me – this is my first desktop install of a 64 bit OS and things like this are what I was reluctant to find. Now that I ran into this I have a good idea what to look for with 32/64 bit misconfigurations in IIS at least.© Rick Strahl, West Wind Technologies, 2005-2011Posted in IIS7   ASP.NET

• Add keyboard languages to XP, Vista, and Windows 7

  - by Matthew Guay

  Do you regularly need to type in multiple languages in Windows?  Here we’ll show you the easy way to add and change input languages to your keyboard in XP, Vista, and Windows 7. Windows Vista and 7 come preinstalled with support for viewing a wide variety of languages, so adding an input language is fairly simply.  Adding an input language is slightly more difficult in XP, and requires installing additional files if you need an Asian or Complex script language.  First we show how to add an input language in Windows Vista and 7; it’s basically the same in both versions.  Then, we show how to add a language to XP, and also how to add Complex Script support.  Please note that this is only for adding an input language, which will allow you to type in the language you select.  This does not change your user interface language. Change keyboard language in Windows 7 and Vista It is fairly simple to add or change a keyboard language in Windows 7 or Vista.  In Windows 7, enter “keyboard language” in the Start menu search box, and select “Change keyboards or other input methods”. In Windows Vista, open Control Panel and enter “input language” in the search box and select “Change keyboards or other input methods”.  This also works in Windows 7. Now, click Change Keyboards to add another keyboard language or change your default one. Our default input language is US English, and our default keyboard is the US keyboard layout.  Click Add to insert another input language while still leaving your default input language installed. Here we selected the standard Thai keyboard language (Thai Kedmanee), but you can select any language you want.  Windows offers almost any language you can imagine, so just look for the language you want, select it, and click Ok. Alternately, if you want, you can click Preview to see your layout choice before accepting it.  This is only the default characters, not ones that will be activated with Shift or other keys (many Asian languages use many more characters than English, and require the use of Shift and other keys to access them all).  Once your finished previewing, click close and then press Ok on the previous dialog. Now you will see both of your keyboard languages in the Installed services box.  You can click Add to go back and get more, or move your selected language up or down (to change its priority), or simply click Apply to add the new language. Also, you can now change the default input language from the top menu.  This is the language that your keyboard will start with when you boot your computer.  So, if you mainly use English but also use another language, usually it is best to leave English as your default input language. Once you’ve pressed Apply or Ok, you will see a new icon beside your system tray with the initials of your default input language. If you click it, you can switch between input languages.  Alternately you can switch input languages by pressing Alt+Shift on your keyboard. Some complex languages, such as Chinese, may have extra buttons to change input modes to accommodate their large alphabet. If you would like to change the keyboard shortcut for changing languages, go back to the Input Languages dialog, and select the “Advanced Key Settings” tab.  Here you can change settings for Caps Lock and change or add key sequences to change between languages. Also, the On-Screen keyboard will display the correct keyboard language (here the keyboard is displaying Thai), which can be a helpful reference if your physical keyboard doesn’t have your preferred input language printed on it.  To open this, simply enter “On-Screen keyboard” in the start menu search, or click All Programs>Accessories>On-Screen keyboard. Change keyboard language in Windows XP The process for changing the keyboard language in Windows XP is slightly different.  Open Control Panel, and select “Date, Time, Language, and Regional Options”.   Select “Add other languages”. Now, click Details to add another language.  XP does not include support for Asian and complex languages by default, so if you need to add one of those languages we have details for that below. Click Add to add an input language. Select your desired language from the list, and choose your desired keyboard layout if your language offers multiple layouts.  Here we selected Canadian French with the default layout. Now you will see both of your keyboard languages in the Installed services box.  You can click Add to go back and add more, or move your selected language up or down (to change its priority), or simply click Apply to add the new language. Once you’ve pressed Apply or Ok, you will see a new icon beside your system tray with the initials of your default input language. If you click it, you can switch between input languages.  Alternately you can switch input languages by pressing Alt+Shift on your keyboard. If you would like to change the keyboard shortcut for changing languages, go back to the Input Languages dialog, and click the “Key Settings” button on the bottom of the dialog.  Here you can change settings for Caps Lock and change or add key sequences to change between languages. Add support to XP for Asian and Complex script languages Windows XP does not include support for Asian and Complex script languages by default, but you can easily add them to your computer.  This is useful if you wish to type in one of these languages, or simply want to read text written in these languages, since XP will not display these languages correctly if they are not installed.  If you wish to install Chinese, Japanese, and/or Korean, check the “Install files for East Asian languages” box.  Or, if you need to install a complex script language (including Arabic, Armenian, Georgian, Hebrew, the Indic languages, Thai, and Vietnamese), check the “Install files for complex script and right-to-left languages” box.   Choosing either of these options will open a prompt reminding you that this option will take up more disk space.  Support for complex languages will require around 10Mb of hard drive space, but East Asian language support may require 230 Mb or more free disk space.  Click Ok, and click apply to install your language files. You may have to insert your XP CD into your CD drive to install these files.  Insert the disk, and then click Ok. Windows will automatically copy the files, including fonts for these languages… …and then will ask you to reboot your computer to finalize the settings.  Click Yes, and then reopen the “Add other languages” dialog when your computer is rebooted, and add a language as before.     Now you can add Complex and/or Asian languages to XP, just as above.  Here is the XP taskbar language selector with Thai installed. Conclusion Unfortunately we haven’t found a way to add Asian and complex languages in XP without having an XP disc. If you know of a way, let us know in the comments. (No downloading the XP disc from torrent site answers please) Adding an input language is very important for bilingual individuals, and can also be useful if you simply need to occasionally view Asian or Complex languages in XP.  And by following the correct instructions for your version of Windows, it should be very easy to add, change, and remove input languages.

• Try out Windows Phone 7 on your PC today

  - by Matthew Guay

  Anticipation has been building for the new Windows Phone 7 Series ever since Microsoft unveiled it at the Mobile World Congress in February.  Now, thanks to free developer tools, you can get a first-hand experience of the basic Windows Phone 7 Series devices on your PC. Windows Phone 7 Series represents a huge change in the mobile field for Microsoft, bringing the acclaimed Zune HD UI to an innovative phone platform.  Windows Mobile has often been criticized for being behind other Smartphone platforms, but Microsoft seeks to regain the lead with this new upcoming release.  A platform must have developers behind it to be useful, so they have released a full set of free development tools so anyone can make apps for it today.  Or, if you simply want to play with Windows Phone 7, you can use the included emulator to try out the new Metro UI.  Here’s how to do this today on your Vista or 7 computer. Please note: These tools are a Customer Technology Preview release, so only install them if you’re comfortable using pre-release software. Getting Started First, download the Windows Phone Developer Tools CTP (link below), and run the installer.  This will install the Customer Technology Preview (CTP) versions of Visual Studio 2010 Express for Windows Phone, Windows Phone Emulator, Silverlight for Windows Phone, and XNA 4.0 Game Studio on your computer, all of which are required and cannot be installed individually. Accept the license agreement when prompted. Click “Install Now” to install the tools you need.  The only setup customization option is where to save the files, so choose Customize if you need to do so. Setup will now automatically download and install the components you need, and will additionally download either 32 or 64 bit programs depending on your operating system. About halfway thorough the installation, you’ll be prompted to reboot your system.  Once your computer is rebooted, setup will automatically resume without further input.   When setup is finished, click “Run the Product Now” to get started. Running Windows Phone 7 on your PC Now that you’ve got the Windows Phone Developer tools installed, it’s time to get the Windows Phone emulator running.  If you clicked “Run the Product Now” when the setup finished, Visual Studio 2010 Express for Windows Phone should have already started.   If not, simply enter “visual studio” in your start menu search and select “Microsoft Visual Studio 2010 Express for Windows Phone”. Now, to run the Windows Phone 7 emulator, we have to test an application.  So, even if you don’t know how to program, we can open a phone application template, and then test it to run the emulator.  First, click New Project on the left hand side of the front page. Any of the application templates would work for this, but here let’s select “Windows Phone Application”, and then click Ok. Here’s your new application template, which already contains the basic phone application framework.  This is where you’d start if you want to develop a Windows Phone app, but for now we just want to see Windows Phone 7 in action. So, to run the emulator, click Debug in the menu and then select Start Debugging. Your new application will launch inside the Windows Phone 7 Series emulator.  The default template doesn’t give us much, but it does show an example application running in Windows Phone 7.   Exploring Windows Phone 7 Click the Windows button on the emulator to go to the home screen.  Notice the Zune HD-like transition animation.  The emulator only includes Internet Explorer, your test application, and a few settings. Click the arrow on the right to see the available applications in a list. Settings lets you change the theme, regional settings, and the date and time in your emulator.  It also has an applications settings pane, but this currently isn’t populated. The Time settings shows a unique Windows Phone UI. You can return to the home screen by pressing the Windows button.  Here’s the Internet Explorer app running, with the virtual keyboard open to enter an address.  Please note that this emulator can also accept input from your keyboard, so you can enter addresses without clicking on the virtual keyboard. And here’s Google running in Internet Explorer on Windows Phone 7. Windows Phone 7 supports accelerometers, and you can simulate this in the emulator.  Click one of the rotate buttons to rotate the screen in that direction. Here’s our favorite website in Internet Explorer on Windows Phone 7 in landscape mode. All this, running right inside your Windows 7 desktop… Developer tools for Windows Phone 7 Although it may be fun to play with the Windows Phone 7 emulator, developers will be more excited to actually be able to create new and exciting apps for it.  The Windows Phone Developer Tools download includes Visual Studio Express and XNA Game Studio 4.0 which lets you create enticing games and apps for Windows Phones.  All development for Windows Phones will be in C#, Silverlight, and the XNA game framework.  Visual Studio Express for Windows Phone includes templates for these, and additionally has code samples to help you get started with development. Conclusion Many features are still not functional in this preview version, such as the search button and most of the included applications.  However, this still gives you a great way to experience firsthand the future of the Windows Phone platform.  And, for developers, this is your chance to set your mark on the Windows Phone 7 Series even before it is released to the public.  Happy playing and developing!

• VS 2010 SP1 (Beta) and IIS Express

  - by ScottGu

  Last month we released the VS 2010 Service Pack 1 (SP1) Beta.  You can learn more about the VS 2010 SP1 Beta from Jason Zander’s two blog posts about it, and from Scott Hanselman’s blog post that covers some of the new capabilities enabled with it.  You can download and install the VS 2010 SP1 Beta here. IIS Express Earlier this summer I blogged about IIS Express.  IIS Express is a free version of IIS 7.5 that is optimized for developer scenarios.  We think it combines the ease of use of the ASP.NET Web Server (aka Cassini) currently built-into VS today with the full power of IIS.  Specifically: It’s lightweight and easy to install (less than 5Mb download and a quick install) It does not require an administrator account to run/debug applications from Visual Studio It enables a full web-server feature set – including SSL, URL Rewrite, and other IIS 7.x modules It supports and enables the same extensibility model and web.config file settings that IIS 7.x support It can be installed side-by-side with the full IIS web server as well as the ASP.NET Development Server (they do not conflict at all) It works on Windows XP and higher operating systems – giving you a full IIS 7.x developer feature-set on all Windows OS platforms IIS Express (like the ASP.NET Development Server) can be quickly launched to run a site from a directory on disk.  It does not require any registration/configuration steps. This makes it really easy to launch and run for development scenarios. Visual Studio 2010 SP1 adds support for IIS Express – and you can start to take advantage of this starting with last month’s VS 2010 SP1 Beta release. Downloading and Installing IIS Express IIS Express isn’t included as part of the VS 2010 SP1 Beta.  Instead it is a separate ~4MB download which you can download and install using this link (it uses WebPI to install it).  Once IIS Express is installed, VS 2010 SP1 will enable some additional IIS Express commands and dialog options that allow you to easily use it. Enabling IIS Express for Existing Projects Visual Studio today defaults to using the built-in ASP.NET Development Server (aka Cassini) when running ASP.NET Projects: Converting your existing projects to use IIS Express is really easy.  You can do this by opening up the project properties dialog of an existing project, and then by clicking the “web” tab within it and selecting the “Use IIS Express” checkbox. Or even simpler, just right-click on your existing project, and select the “Use IIS Express…” menu command: And now when you run or debug your project you’ll see that IIS Express now starts up and runs automatically as your web-server: You can optionally right-click on the IIS Express icon within your system tray to see/browse all of sites and applications running on it: Note that if you ever want to revert back to using the ASP.NET Development Server you can do this by right-clicking the project again and then select the “Use Visual Studio Development Server” option (or go into the project properties, click the web tab, and uncheck IIS Express).  This will revert back to the ASP.NET Development Server the next time you run the project. IIS Express Properties Visual Studio 2010 SP1 exposes several new IIS Express configuration options that you couldn’t previously set with the ASP.NET Development Server.  Some of these are exposed via the property grid of your project (select the project node in the solution explorer and then change them via the property window): For example, enabling something like SSL support (which is not possible with the ASP.NET Development Server) can now be done simply by changing the “SSL Enabled” property to “True”: Once this is done IIS Express will expose both an HTTP and HTTPS endpoint for the project that we can use: SSL Self Signed Certs IIS Express ships with a self-signed SSL cert that it installs as part of setup – which removes the need for you to install your own certificate to use SSL during development.  Once you change the above drop-down to enable SSL, you’ll be able to browse to your site with the appropriate https:// URL prefix and it will connect via SSL. One caveat with self-signed certificates, though, is that browsers (like IE) will go out of their way to warn you that they aren’t to be trusted: You can mark the certificate as trusted to avoid seeing dialogs like this – or just keep the certificate un-trusted and press the “continue” button when the browser warns you not to trust your local web server. Additional IIS Settings IIS Express uses its own per-user ApplicationHost.config file to configure default server behavior.  Because it is per-user, it can be configured by developers who do not have admin credentials – unlike the full IIS.  You can customize all IIS features and settings via it if you want ultimate server customization (for example: to use your own certificates for SSL instead of self-signed ones). We recommend storing all app specific settings for IIS and ASP.NET within the web.config file which is part of your project – since that makes deploying apps easier (since the settings can be copied with the application content).  IIS (since IIS 7) no longer uses the metabase, and instead uses the same web.config configuration files that ASP.NET has always supported – which makes xcopy/ftp based deployment much easier. Making IIS Express your Default Web Server Above we looked at how we can convert existing sites that use the ASP.NET Developer Web Server to instead use IIS Express.  You can configure Visual Studio to use IIS Express as the default web server for all new projects by clicking the Tools->Options menu  command and opening up the Projects and Solutions->Web Projects node with the Options dialog: Clicking the “Use IIS Express for new file-based web site and projects” checkbox will cause Visual Studio to use it for all new web site and projects. Summary We think IIS Express makes it even easier to build, run and test web applications.  It works with all versions of ASP.NET and supports all ASP.NET application types (including obviously both ASP.NET Web Forms and ASP.NET MVC applications).  Because IIS Express is based on the IIS 7.5 codebase, you have a full web-server feature-set that you can use.  This means you can build and run your applications just like they’ll work on a real production web-server.  In addition to supporting ASP.NET, IIS Express also supports Classic ASP and other file-types and extensions supported by IIS – which also makes it ideal for sites that combine a variety of different technologies. Best of all – you do not need to change any code to take advantage of it.  As you can see above, updating existing Visual Studio web projects to use it is trivial.  You can begin to take advantage of IIS Express today using the VS 2010 SP1 Beta. Hope this helps, Scott
