• Adventures in Windows 8: Solving activation errors

  - by Laurent Bugnion

  Note: I tagged this article with “MVVM” because I got a few support requests for MVVM Light regarding this exact issue. In fact it is a Windows 8 issue and has nothing to do with MVVM Light per se… Sometimes when you work on a Windows 8 app, you will get a very annoying issue when starting the app. In that case, the app doesn’t not even start past the Splash screen. Putting a breakpoint in App.xaml.cs doesn’t help because the app doesn’t even reach that point! So what exactly is happening? Well when a Windows 8 app starts, the system is performing a few check first. One of the checks, for instance, is to see if an app with the same package ID is already available. The package ID is a unique value set in the package manifest. In the Solution Explorer, double click on Package.appxmanifest. This opens the manifest in a special editor Click on the Packaging tab See the GUID under Package Name. This is the unique ID I am talking about. If there is a conflict (i.e. if an app is already installed with the exact same ID), Windows will warm the user that the app is already installed. However when you are in the process of developing an app, you install and uninstall the same app many many times (every time that you start in Visual Studio), and sometimes some issues arise, for instance failing to uninstall the app before starting the new instance of the same app. First step if you get such an error When the application fails to start past the splash screen, the first step is to identify what kind of error happened. In my experience the “already installed” is by far the most frequent (in fact I never had another such error), but it can be something else. An annoying thing is that the popup that shows the error is usually started below the Windows 8 app, and so you don’t even see it! This is especially true if you run this in the Simulator. In that case, do the following: Press on the Simulator’s home button, then press on the Desktop tile on the Start menu. The error popup should be shown on the desktop. If your applications runs on the Local machine, you also do the same and press the Windows button, and then from the Start menu press the Desktop tile. Deployment error in Studio Sometimes the same error causes Visual Studio to fail launching the application at all with a deployment error. This is a better case, because at least it is clear that there is an issue. In that case, write down the code that is shown in the Error window (for instance 0x80073D05 in the example below). Once you have the error code, go to the “Troubleshooting packaging, deployment, and query of Windows Store apps” page and look up the code in question. In my case, the error was “ERROR_DELETING_EXISTING_APPLICATIONDATA_STORE_FAILED”, “An error occurred while deleting the package's previously existing application data.” Solving the “ERROR_DELETING_EXISTING_APPLICATIONDATA_STORE_FAILED” issue Update: Before trying the below, you can also try the simple steps: Exit Visual Studio Go to the Start menu Locate your app’s tile. It should be visible in the Start menu directly, towards the far end on the right. Right click the tile and select Uninstall from the App Bar. Restart Visual Studio and try again. Sometimes it helps. If it doesn’t, then try the following: In order to solve the case where Windows, for any reason, fails to delete the existing application before starting the new instance, follow the steps: Open the Package.appxmanifest in Visual Studio Open the Packaging tab. Change the Package name. For tests you can just try to change the last character of the GUID, though I would recommend creating a brand new GUID. Press Start Type GUID Start the GUID Generator application Select Registry Format Press Copy. Paste the new GUID in place of the Package Name in Visual Studio Important: don’t forget to remove the curly brackets at the beginning and at the end of the newly pasted GUID. Then you just have to cross your fingers and start the application again… If it works, celebrate. if it doesn’t work… well at this point I am not sure so good luck with that ;) Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Data Source Security Part 2

  - by Steve Felts

  In Part 1, I introduced the default security behavior and listed the various options available to change that behavior.  One of the key topics to understand is the difference between directly using database user and password values versus mapping from WLS user and password to the associated database values.   The direct use of database credentials is relatively new to WLS, based on customer feedback.  Some of the trade-offs are covered in this article. Credential Mapping vs. Database Credentials Each WLS data source has a credential map that is a mechanism used to map a key, in this case a WLS user, to security credentials (user and password).  By default, when a user and password are specified when getting a connection, they are treated as credentials for a WLS user, validated, and are converted to a database user and password using a credential map associated with the data source.  If a matching entry is not found in the credential map for the data source, then the user and password associated with the data source definition are used.  Because of this defaulting mechanism, you should be careful what permissions are granted to the default user.  Alternatively, you can define an invalid default user to ensure that no one can accidentally get through (in this case, you would need to set the initial capacity for the pool to zero so that the pool is populated only by valid users). To create an entry in the credential map: 1) First create a WLS user.  In the administration console, go to Security realms, select your realm (e.g., myrealm), select Users, and select New.  2) Second, create the mapping.  In the administration console, go to Services, select Data sources, select your data source name, select Security, select Credentials, and select New.  See http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/ConfigureCredentialMappingForADataSource.html for more information. The advantages of using the credential mapping are that: 1) You don’t hard-code the database user/password into a program or need to prompt for it in addition to the WLS user/password and 2) It provides a layer of abstraction between WLS security and database settings such that many WLS identities can be mapped to a smaller set of DB identities, thereby only requiring middle-tier configuration updates when WLS users are added/removed. You can cut down the number of users that have access to a data source to reduce the user maintenance overhead.  For example, suppose that a servlet has the one pre-defined, special WLS user/password for data source access, hard-wired in its code in a getConnection(user, password) call.  Every WebLogic user can reap the specific DBMS access coded into the servlet, but none has to have general access to the data source.  For instance, there may be a ‘Sales’ DBMS which needs to be protected from unauthorized eyes, but it contains some day-to-day data that everyone needs. The Sales data source is configured with restricted access and a servlet is built that hard-wires the specific data source access credentials in its connection request.  It uses that connection to deliver only the generally needed day-to-day information to any caller. The servlet cannot reveal any other data, and no WebLogic user can get any other access to the data source.  This is the approach that many large applications take and is the reasoning behind the default mapping behavior in WLS. The disadvantages of using the credential map are that: 1) It is difficult to manage (create, update, delete) with a large number of users; it is possible to use WLST scripts or a custom JMX client utility to manage credential map entries. 2) You can’t share a credential map between data sources so they must be duplicated. Some applications prefer not to use the credential map.  Instead, the credentials passed to getConnection(user, password) should be treated as database credentials and used to authenticate with the database for the connection, avoiding going through the credential map.  This is enabled by setting the “use-database-credentials” to true.  See http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/ConfigureOracleParameters.html "Configure Oracle parameters" in Oracle WebLogic Server Administration Console Help. Use Database Credentials is not currently supported for Multi Data Source configurations.  When enabled, it turns off credential mapping on Generic and Active GridLink data sources for the following attributes: 1. identity-based-connection-pooling-enabled (this interaction is available by patch in 10.3.6.0). 2. oracle-proxy-session (this interaction is first available in 10.3.6.0). 3. set client identifier (this interaction is available by patch in 10.3.6.0).  Note that in the data source schema, the set client identifier feature is poorly named “credential-mapping-enabled”.  The documentation and the console refer to it as Set Client Identifier. To review the behavior of credential mapping and using database credentials: - If using the credential map, there needs to be a mapping for each WLS user to database user for those users that will have access to the database; otherwise the default user for the data source will be used.  If you always specify a user/password when getting a connection, you only need credential map entries for those specific users. - If using database credentials without specifying a user/password, the default user and password in the data source descriptor are always used.  If you specify a user/password when getting a connection, that user will be used for the credentials.  WLS users are not involved at all in the data source connection process.

• Simple BizTalk Orchestration & Port Tutorial

  - by bosuch

  (This is a reference for a lunch & learn I'm giving at my company) This demo will create a BizTalk process that monitors a directory for an XML file, loads it into an orchestration, and drops it into a different directory. There’s no real processing going on (other than moving the file from one location to another), but this will introduce you to Messages, Orchestrations and Ports. To begin, create a new BizTalk Project names OrchestrationPortDemo: When the solution has been created, right-click the OrchestrationPortDemo solution name and select Add -> New Item. Add a BizTalk Orchestration named DemoOrchestration: Click Add and the orchestration will be created and displayed in the BizTalk Orchestration Designer. The designer allows you to visually create your business processes: Next, you will add a message (the basic unit of communication) to the orchestration. In the Orchestration View, right-click Messages and select New Message. In the message properties window, enter DemoMessage as the Identifier (the name), and select .NET Classes -> System.Xml.XmlDocument for Message Type. This indicates that we’ll be passing a standard Xml document in and out of the orchestration. Next, you will add Send and Receive shapes to the orchestration. From the toolbox, drag a Receive shape onto the orchestration (where it says “Drop a shape from the toolbox here”). Next, drag a Send shape directly below the Receive shape. For the properties of both shapes, select DemoMessage for Message – this indicates we’ll be passing around the message we created earlier. The Operation box will have a red exclamation mark next to it because no port has been specified. We will do this in a minute. On the Receive shape properties, you must be sure to select True for Activate. This indicates that the orchestration will be started upon receipt of a message, rather than being called by another orchestration. If you leave it set to false, when you try to build the application you’ll receive the error “You must specify at least one already-initialized correlation set for a non-activation receive that is on a non self-correlating port.” Now you’ll add ports to the orchestration. Ports specify how your orchestration will send and receive messages. Drag a port from the toolbox to the left-hand Port Surface, and the Port Configuration Wizard launches. For the first port (the receive port), enter the following information: Name: ReceivePort Select the port type to be used for this port: Create a new Port Type Port Type Name: ReceivePortType Port direction of communication: I’ll always be receiving <…> Port binding: Specify later By choosing “Specify later” you are choosing to bind the port (choose where and how it will send or receive its messages) at deployment time via the BizTalk Server Administration console. This allows you to change locations later without building and re-deploying the application. Next, drag a port to the right-hand Port Surface; this will be your send port. Configure it as follows: Name: SendPort Select the port type to be used for this port: Create a new Port Type Port Type Name: SendPortType Port direction of communication: I’ll always be sending <…> Port binding: Specify later Finally, drag the green arrow on the ReceivePort to the Receive_1 shape, and the green arrow on the SendPort to the Send_1 shape. Your orchestration should look like this: Now you have a couple final steps before building and deploying the application. In the Solution Explorer, right-click on OrchestrationPortDemo and select Properties. On the Signing tab, click “Sign the assembly”, and choose <New…> from the drop-down. Enter DemoKey as the Key file name, and deselect “Protect my key file with a password”. This will create the file DemoKey.snk in your solution. Signing the assembly gives it a strong name so that it can be deployed into the global assembly cache (GAC). Next, click the Deployment tab, and enter OrchestrationPortDemo as the Application Name. Save your solution. Click “Build OrchestrationPortDemo”. Your solution should (hopefully!) build with no errors. Click “Deploy OrchestrationPortDemo”. (Note – If you’re running Server 2008, Vista or Win7, you may get an error message. If so, close Visual Studio and run it as an administrator) That’s it! Your application is ready to be configured and fired up in the BizTalk Server Administration console, so stay tuned!

• WPF TreeView MouseDown

  - by imekon

  I've got something like this in a TreeView: <DataTemplate x:Key="myTemplate"> <StackPanel MouseDown="OnItemMouseDown"> ... </StackPanel> </DataTemplate> Using this I get the mouse down events if I click on items in the stack panel. However... there seems to be another item behind the stack panel that is the TreeViewItem - it's very hard to hit, but not impossible, and that's when the problems start to occur. I had a go at handling PreviewMouseDown on TreeViewItem, however that seems to require e.Handled = false otherwise standard tree view behaviour stops working. Ok, Here's the source code... MainWindow.xaml <Window x:Class="WPFMultiSelectTree.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WPFMultiSelectTree" Title="Multiple Selection Tree" Height="300" Width="300"> <Window.Resources> <!-- Declare the classes that convert bool to Visibility --> <local:VisibilityConverter x:Key="visibilityConverter"/> <local:VisibilityInverter x:Key="visibilityInverter"/> <!-- Set the style for any tree view item --> <Style TargetType="TreeViewItem"> <Style.Triggers> <DataTrigger Binding="{Binding Selected}" Value="True"> <Setter Property="Background" Value="DarkBlue"/> <Setter Property="Foreground" Value="White"/> </DataTrigger> </Style.Triggers> <EventSetter Event="PreviewMouseDown" Handler="OnTreePreviewMouseDown"/> </Style> <!-- Declare a hierarchical data template for the tree view items --> <HierarchicalDataTemplate x:Key="RecursiveTemplate" ItemsSource="{Binding Children}"> <StackPanel Margin="2" Orientation="Horizontal" MouseDown="OnTreeMouseDown"> <Ellipse Width="12" Height="12" Fill="Green"/> <TextBlock Margin="2" Text="{Binding Name}" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}"/> <TextBox Margin="2" Text="{Binding Name}" KeyDown="OnTextBoxKeyDown" IsVisibleChanged="OnTextBoxIsVisibleChanged" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}"/> <TextBlock Margin="2" Text="{Binding Index, StringFormat=({0})}"/> </StackPanel> </HierarchicalDataTemplate> <!-- Declare a simple template for a list box --> <DataTemplate x:Key="ListTemplate"> <TextBlock Text="{Binding Name}"/> </DataTemplate> </Window.Resources> <Grid> <!-- Declare the rows in this grid --> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition/> <RowDefinition Height="Auto"/> <RowDefinition/> </Grid.RowDefinitions> <!-- The first header --> <TextBlock Grid.Row="0" Margin="5" Background="PowderBlue">Multiple selection tree view</TextBlock> <!-- The tree view --> <TreeView Name="m_tree" Margin="2" Grid.Row="1" ItemsSource="{Binding Children}" ItemTemplate="{StaticResource RecursiveTemplate}"/> <!-- The second header --> <TextBlock Grid.Row="2" Margin="5" Background="PowderBlue">The currently selected items in the tree</TextBlock> <!-- The list box --> <ListBox Name="m_list" Margin="2" Grid.Row="3" ItemsSource="{Binding .}" ItemTemplate="{StaticResource ListTemplate}"/> </Grid> </Window> MainWindow.xaml.cs /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { private Container m_root; private Container m_first; private ObservableCollection<Container> m_selection; private string m_current; /// <summary> /// Constructor /// </summary> public MainWindow() { InitializeComponent(); m_selection = new ObservableCollection<Container>(); m_root = new Container("root"); for (int parents = 0; parents < 50; parents++) { Container parent = new Container(String.Format("parent{0}", parents + 1)); for (int children = 0; children < 1000; children++) { parent.Add(new Container(String.Format("child{0}", children + 1))); } m_root.Add(parent); } m_tree.DataContext = m_root; m_list.DataContext = m_selection; m_first = null; } /// <summary> /// Has the shift key been pressed?

• SQLite, python, unicode, and non-utf data

  - by Nathan Spears

  I started by trying to store strings in sqlite using python, and got the message: sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings. Ok, I switched to Unicode strings. Then I started getting the message: sqlite3.OperationalError: Could not decode to UTF-8 column 'tag_artist' with text 'Sigur Rós' when trying to retrieve data from the db. More research and I started encoding it in utf8, but then 'Sigur Rós' starts looking like 'Sigur Rós' note: My console was set to display in 'latin_1' as @John Machin pointed out. What gives? After reading this, describing exactly the same situation I'm in, it seems as if the advice is to ignore the other advice and use 8-bit bytestrings after all. I didn't know much about unicode and utf before I started this process. I've learned quite a bit in the last couple hours, but I'm still ignorant of whether there is a way to correctly convert 'ó' from latin-1 to utf-8 and not mangle it. If there isn't, why would sqlite 'highly recommend' I switch my application to unicode strings? I'm going to update this question with a summary and some example code of everything I've learned in the last 24 hours so that someone in my shoes can have an easy(er) guide. If the information I post is wrong or misleading in any way please tell me and I'll update, or one of you senior guys can update. Summary of answers Let me first state the goal as I understand it. The goal in processing various encodings, if you are trying to convert between them, is to understand what your source encoding is, then convert it to unicode using that source encoding, then convert it to your desired encoding. Unicode is a base and encodings are mappings of subsets of that base. utf_8 has room for every character in unicode, but because they aren't in the same place as, for instance, latin_1, a string encoded in utf_8 and sent to a latin_1 console will not look the way you expect. In python the process of getting to unicode and into another encoding looks like: str.decode('source_encoding').encode('desired_encoding') or if the str is already in unicode str.encode('desired_encoding') For sqlite I didn't actually want to encode it again, I wanted to decode it and leave it in unicode format. Here are four things you might need to be aware of as you try to work with unicode and encodings in python. The encoding of the string you want to work with, and the encoding you want to get it to. The system encoding. The console encoding. The encoding of the source file Elaboration: (1) When you read a string from a source, it must have some encoding, like latin_1 or utf_8. In my case, I'm getting strings from filenames, so unfortunately, I could be getting any kind of encoding. Windows XP uses UCS-2 (a Unicode system) as its native string type, which seems like cheating to me. Fortunately for me, the characters in most filenames are not going to be made up of more than one source encoding type, and I think all of mine were either completely latin_1, completely utf_8, or just plain ascii (which is a subset of both of those). So I just read them and decoded them as if they were still in latin_1 or utf_8. It's possible, though, that you could have latin_1 and utf_8 and whatever other characters mixed together in a filename on Windows. Sometimes those characters can show up as boxes, other times they just look mangled, and other times they look correct (accented characters and whatnot). Moving on. (2) Python has a default system encoding that gets set when python starts and can't be changed during runtime. See here for details. Dirty summary ... well here's the file I added: \# sitecustomize.py \# this file can be anywhere in your Python path, \# but it usually goes in ${pythondir}/lib/site-packages/ import sys sys.setdefaultencoding('utf_8') This system encoding is the one that gets used when you use the unicode("str") function without any other encoding parameters. To say that another way, python tries to decode "str" to unicode based on the default system encoding. (3) If you're using IDLE or the command-line python, I think that your console will display according to the default system encoding. I am using pydev with eclipse for some reason, so I had to go into my project settings, edit the launch configuration properties of my test script, go to the Common tab, and change the console from latin-1 to utf-8 so that I could visually confirm what I was doing was working. (4) If you want to have some test strings, eg test_str = "ó" in your source code, then you will have to tell python what kind of encoding you are using in that file. (FYI: when I mistyped an encoding I had to ctrl-Z because my file became unreadable.) This is easily accomplished by putting a line like so at the top of your source code file: # -*- coding: utf_8 -*- If you don't have this information, python attempts to parse your code as ascii by default, and so: SyntaxError: Non-ASCII character '\xf3' in file _redacted_ on line 81, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details Once your program is working correctly, or, if you aren't using python's console or any other console to look at output, then you will probably really only care about #1 on the list. System default and console encoding are not that important unless you need to look at output and/or you are using the builtin unicode() function (without any encoding parameters) instead of the string.decode() function. I wrote a demo function I will paste into the bottom of this gigantic mess that I hope correctly demonstrates the items in my list. Here is some of the output when I run the character 'ó' through the demo function, showing how various methods react to the character as input. My system encoding and console output are both set to utf_8 for this run: '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Now I will change the system and console encoding to latin_1, and I get this output for the same input: 'ó' = original char <type 'str'> repr(char)='\xf3' 'ó' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Notice that the 'original' character displays correctly and the builtin unicode() function works now. Now I change my console output back to utf_8. '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' '?' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Here everything still works the same as last time but the console can't display the output correctly. Etc. The function below also displays more information that this and hopefully would help someone figure out where the gap in their understanding is. I know all this information is in other places and more thoroughly dealt with there, but I hope that this would be a good kickoff point for someone trying to get coding with python and/or sqlite. Ideas are great but sometimes source code can save you a day or two of trying to figure out what functions do what. Disclaimers: I'm no encoding expert, I put this together to help my own understanding. I kept building on it when I should have probably started passing functions as arguments to avoid so much redundant code, so if I can I'll make it more concise. Also, utf_8 and latin_1 are by no means the only encoding schemes, they are just the two I was playing around with because I think they handle everything I need. Add your own encoding schemes to the demo function and test your own input. One more thing: there are apparently crazy application developers making life difficult in Windows. #!/usr/bin/env python # -*- coding: utf_8 -*- import os import sys def encodingDemo(str): validStrings = () try: print "str =",str,"{0} repr(str) = {1}".format(type(str), repr(str)) validStrings += ((str,""),) except UnicodeEncodeError as ude: print "Couldn't print the str itself because the console is set to an encoding that doesn't understand some character in the string.

• Problem interfacing GSM USB modem to Java application

  - by varun

  I am working on an open-source application called FrontlineSMS which can be interfaced with GSM modems to send and receive SMS. The windows installer that is available through their website works fine. Since i wanted to modify it, I got the source code and built the jar and tried to launch it. When I plug in the GSM modem and launch the application, it sometimes detects the GSM device and i am even able to send and receive SMS. Or else 1.) I get the following error- Launching FrontlineSMS for Windows...

• SQLite, python, unicode, and non-utf data

  - by Nathan Spears

  I started by trying to store strings in sqlite using python, and got the message: sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings. Ok, I switched to Unicode strings. Then I started getting the message: sqlite3.OperationalError: Could not decode to UTF-8 column 'tag_artist' with text 'Sigur Rós' when trying to retrieve data from the db. More research and I started encoding it in utf8, but then 'Sigur Rós' starts looking like 'Sigur Rós' note: My console was set to display in 'latin_1' as @John Machin pointed out. What gives? After reading this, describing exactly the same situation I'm in, it seems as if the advice is to ignore the other advice and use 8-bit bytestrings after all. I didn't know much about unicode and utf before I started this process. I've learned quite a bit in the last couple hours, but I'm still ignorant of whether there is a way to correctly convert 'ó' from latin-1 to utf-8 and not mangle it. If there isn't, why would sqlite 'highly recommend' I switch my application to unicode strings? I'm going to update this question with a summary and some example code of everything I've learned in the last 24 hours so that someone in my shoes can have an easy(er) guide. If the information I post is wrong or misleading in any way please tell me and I'll update, or one of you senior guys can update. Summary of answers Let me first state the goal as I understand it. The goal in processing various encodings, if you are trying to convert between them, is to understand what your source encoding is, then convert it to unicode using that source encoding, then convert it to your desired encoding. Unicode is a base and encodings are mappings of subsets of that base. utf_8 has room for every character in unicode, but because they aren't in the same place as, for instance, latin_1, a string encoded in utf_8 and sent to a latin_1 console will not look the way you expect. In python the process of getting to unicode and into another encoding looks like: str.decode('source_encoding').encode('desired_encoding') or if the str is already in unicode str.encode('desired_encoding') For sqlite I didn't actually want to encode it again, I wanted to decode it and leave it in unicode format. Here are four things you might need to be aware of as you try to work with unicode and encodings in python. The encoding of the string you want to work with, and the encoding you want to get it to. The system encoding. The console encoding. The encoding of the source file Elaboration: (1) When you read a string from a source, it must have some encoding, like latin_1 or utf_8. In my case, I'm getting strings from filenames, so unfortunately, I could be getting any kind of encoding. Windows XP uses UCS-2 (a Unicode system) as its native string type, which seems like cheating to me. Fortunately for me, the characters in most filenames are not going to be made up of more than one source encoding type, and I think all of mine were either completely latin_1, completely utf_8, or just plain ascii (which is a subset of both of those). So I just read them and decoded them as if they were still in latin_1 or utf_8. It's possible, though, that you could have latin_1 and utf_8 and whatever other characters mixed together in a filename on Windows. Sometimes those characters can show up as boxes, other times they just look mangled, and other times they look correct (accented characters and whatnot). Moving on. (2) Python has a default system encoding that gets set when python starts and can't be changed during runtime. See here for details. Dirty summary ... well here's the file I added: \# sitecustomize.py \# this file can be anywhere in your Python path, \# but it usually goes in ${pythondir}/lib/site-packages/ import sys sys.setdefaultencoding('utf_8') This system encoding is the one that gets used when you use the unicode("str") function without any other encoding parameters. To say that another way, python tries to decode "str" to unicode based on the default system encoding. (3) If you're using IDLE or the command-line python, I think that your console will display according to the default system encoding. I am using pydev with eclipse for some reason, so I had to go into my project settings, edit the launch configuration properties of my test script, go to the Common tab, and change the console from latin-1 to utf-8 so that I could visually confirm what I was doing was working. (4) If you want to have some test strings, eg test_str = "ó" in your source code, then you will have to tell python what kind of encoding you are using in that file. (FYI: when I mistyped an encoding I had to ctrl-Z because my file became unreadable.) This is easily accomplished by putting a line like so at the top of your source code file: # -*- coding: utf_8 -*- If you don't have this information, python attempts to parse your code as ascii by default, and so: SyntaxError: Non-ASCII character '\xf3' in file _redacted_ on line 81, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details Once your program is working correctly, or, if you aren't using python's console or any other console to look at output, then you will probably really only care about #1 on the list. System default and console encoding are not that important unless you need to look at output and/or you are using the builtin unicode() function (without any encoding parameters) instead of the string.decode() function. I wrote a demo function I will paste into the bottom of this gigantic mess that I hope correctly demonstrates the items in my list. Here is some of the output when I run the character 'ó' through the demo function, showing how various methods react to the character as input. My system encoding and console output are both set to utf_8 for this run: '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Now I will change the system and console encoding to latin_1, and I get this output for the same input: 'ó' = original char <type 'str'> repr(char)='\xf3' 'ó' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Notice that the 'original' character displays correctly and the builtin unicode() function works now. Now I change my console output back to utf_8. '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' '?' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Here everything still works the same as last time but the console can't display the output correctly. Etc. The function below also displays more information that this and hopefully would help someone figure out where the gap in their understanding is. I know all this information is in other places and more thoroughly dealt with there, but I hope that this would be a good kickoff point for someone trying to get coding with python and/or sqlite. Ideas are great but sometimes source code can save you a day or two of trying to figure out what functions do what. Disclaimers: I'm no encoding expert, I put this together to help my own understanding. I kept building on it when I should have probably started passing functions as arguments to avoid so much redundant code, so if I can I'll make it more concise. Also, utf_8 and latin_1 are by no means the only encoding schemes, they are just the two I was playing around with because I think they handle everything I need. Add your own encoding schemes to the demo function and test your own input. One more thing: there are apparently crazy application developers making life difficult in Windows. #!/usr/bin/env python # -*- coding: utf_8 -*- import os import sys def encodingDemo(str): validStrings = () try: print "str =",str,"{0} repr(str) = {1}".format(type(str), repr(str)) validStrings += ((str,""),) except UnicodeEncodeError as ude: print "Couldn't print the str itself because the console is set to an encoding that doesn't understand some character in the string.

• client problems - misaligned expectations & not following SDLC protocols

  - by louism

  hi guys, im having some serious problems with a client on a project - i could use some advice please the short version i have been working with this client now for almost 6 months without any problems (a classified website project in the range of 500 hours) over the last few days things have drastically deteriorated to the point where ive had to place the project on-hold whilst i work-out what to do (this has pissed the client off even more) to be simplistic, the root cause of the issue is this: the client doesnt read the specs i make for him, i code the feature, he than wants to change things, i tell him its not to the agreed spec and that that change will have to be postponed and possibly charged for, he gets upset and rants saying 'hes paid for the feature' and im not keeping to the agreement (<- misalignment of expectations) i think the root cause of the root cause is my clients failure to take my SDLC protocols seriously. i have a bug tracking system in place which he practically refuses to use (he still emails me bugs), he doesnt seem to care to much for the protocols i use for dealing with scope creep and change control the whole situation came to a head recently where he 'cracked it' (an aussie term for being fed-up). the more terms like 'postponed for post-launch implementation', 'costed feature addition', and 'not to agreed spec' i kept using, the worse it got finally, he began to bully me - basically insisting i shut-up and do the work im being paid for. i wrote a long-winded email explaining how wrong he was on all these different points, and explaining what all the SDLC protocols do to protect the success of the project. than i deleted that email and wrote a new one in the new email, i suggested as a solution i write up a list of grievances we both had. we than review the list and compromise on different points: he gets some things he wants, i get some things i want. sometimes youve got to give ground to get ground his response to this suggestion was flat-out refusal, and a restatement that i should just get on with the work ive been paid to do so there you have the very subjective short version. if you have the time and inclination, the long version may be a little less bias as it has the email communiques between me and my client the long version (with background) the long version works by me showing you the email communiques which lead to the situation coming to a head. so here it is, judge for yourself where the trouble started... 1. client asked me why something was missing from a feature i just uploaded, my response was to show him what was in the spec: it basically said the item he was looking for was never going to be included 2. [clients response...] Memo Louis, We are following your own title fields and keeping a consistent layout. Why the big fuss about not adding "Part". It simply replaces "model" and is consistent with your current title fields. 3. [my response...] hi [client], the 'part' field appeared to me as a redundancy / mistake. i requested clarification but never received any in a timely manner (about 2 weeks ago) the specification for this feature also indicated it wasnt going to be included: RE: "Why the big fuss about not adding "Part" " it may not appear so, but it would actually be a lot of work for me to now add a 'Part' field it could take me up to 15-20 minutes to properly explain why its such a big undertaking to do this, but i would prefer to use that time instead to work on completing your v1.1 features as a simplistic explanation - it connects to the change in paradigm from a 'generic classified ad' model to a 'specific attributes for specific categories' model basically, i am saying it is a big fuss, but i understand that it doesnt look that way - after all, it is just one ity-bitty field :) if you require a fuller explanation, please let me know and i will commit the time needed to write that out also, if you recall when we first started on the project, i said that with the effort/time required for features, you would likely not know off the top of your head. you may think something is really complex, but in reality its quite simple, you might think something is easy - but it could actually be a massive trauma to code (which is the case here with the 'Part' field). if you also recalled, i said the best course of action is to just ask, and i would let you know on a case-by-case basis 4. [email from me to client...] hi [client], the online catalogue page is now up live (see my email from a few days ago for information on how it works) note: the window of opportunity for input/revisions on what data the catalogue stores has now closed (as i have put the code up live now) RE: the UI/layout of the online catalogue page you may still do visual/ui tweaks to the page at the moment (this window for input/revisions will close in a couple of days time) 5. [email from client to me...] *(note: i had put up the feature & asked the client to review it, never heard back from them for a few days)* Memo Louis, Here you go again. CLOSED without a word of input from the customer. I don't think so. I will reply tomorrow regarding the content and functionality we require from this feature. 5. [from me to client...] hi [client]: RE: from my understanding, you are saying that the mini-sale yard control would change itself based on the fact someone was viewing for parts & accessories <- is that correct? this change is outside the scope of the v1.1 mini-spec and therefore will need to wait 'til post launch for costing/implementation 6. [email from client to me...] Memo Louis, Following your v1.1 mini-spec and all your time paid in full for the work selected. We need to make the situation clear. There will be no further items held for post-launch. Do not expect us to pay for any further items other than those we have agreed upon. You have undertaken to complete the Parts and accessories feature as follows. Obviously, as part of this process the "mini search" will be effected, and will require "adaption to make sense". 7. [email from me to client...] hi [client], RE: "There will be no further items held for post-launch. Do not expect us to pay for any further items other than those we have agreed upon." a few points to consider: 1) the specification for the 'parts & accessories' feature was as follows: (i.e. [what] "...we have agreed upon.") 2) you have received the 'parts & accessories' feature free of charge (you have paid $0 for it). ive spent two days coding that feature as a gesture of good will i would request that you please consider these two facts carefully and sincerely 8. [email from client to me...] Memo Louis, I don't see how you are giving us anything for free. From your original fee proposal you have deleted more than 30 hours of included features. Your title "shelved features". Further you have charged us twice by adding back into the site, at an addition cost, some of those "shelved features" features. See v1.1 mini-spec. Did include in your original fee proposal a change request budget but then charge without discussion items included in v1.1 mini-spec. Included a further Features test plan for a regression test, a fee of 10 hours that would not have been required if the "shelved features" were not left out of the agreed fee proposal. I have made every attempt to satisfy your your uneven business sense by offering you everything your heart desired, in the v1.1 mini-spec, to be left once again with your attitude of "its too hard, lets leave it for post launch". I am no longer accepting anything less than what we have contracted you to do. That is clearly defined in v1.1 mini-spec, and you are paid in advance for delivering those items as an acceptable function. a few notes about the above email... i had to cull features from the original spec because it didnt fit into the budget. i explained this to the client at the start of the project (he wanted more features than he had budget hours to do them all) nothing has been charged for twice, i didnt charge the client for culled features. im charging him to now do those culled features the draft version of the project schedule included a change request budget of 10 hours, but i had to remove that to meet the budget (the client may not have been aware of this to be fair to them) what the client refers to as my attitude of 'too hard/leave it for post-launch', i called a change request protocol and a method for keeping scope creep under control 9. [email from me to client...] hi [client], RE: "...all your grievances..." i had originally written out a long email response; it was fantastic, it had all these great points of how 'you were wrong' and 'i was right', you would of loved it (and by 'loved it', i mean it would of just infuriated you more) so, i decided to deleted it start over, for two reasons: 1) a long email is being disrespectful of your time (youre a busy businessman with things to do) 2) whos wrong or right gets us no closer to fixing the problems we are experiencing what i propose is this... i prepare a bullet point list of your grievances and my grievances (yes, im unhappy too about how things are going - and it has little to do with money) i submit this list to you for you to add to as necessary we then both take a good hard look at this list, and we decide which areas we are willing to give ground on as an example, the list may look something like this: "louis, you keep taking away features you said you would do" [your grievance 2] [your grievance 3] [your grievance ...] "[client], i feel you dont properly read the specs i prepare for you..." [my grievance 2] [my grievance 3] [my grievance ...] if you are willing to give this a try, let me know will it work? who knows. but if it doesnt, we can always go back to arguing some more :) obviously, this will only work if you are willing to give it a genuine try, and you can accept that you may have to 'give some ground to get some ground' what do you think? 10. [email from client to me ...] Memo Louis, Instead of wasting your time listing grievances, I would prefer you complete the items in v1.1 mini-spec, to a satisfactory conclusion. We almost had the website ready for launch until you brought the v1.1 mini-spec into the frame. Obviously I expected you could complete the v1.1 mini-spec in a two-week time frame as you indicated and give the site a more profession presentation. Most of the problems have been caused by you not following our instructions, but deciding to do what you feel like at the time. And then arguing with us how the missing information is not necessary. For instance "Parts and Accessories". Why on earth would you leave out the parts heading, when it ties-in with the fields you have already developed. It replaces "model" and is just as important in the context of information that appears in the "Details" panel. We are at a stage where the the v1.1 mini-spec needs to be completed without further time wasting and the site is complete (subject to all features working). We are on standby at this end to do just that. Let me know when you are back, working on the site and we will process and complete each v1.1 mini-spec, item by item, until the job is complete. 11. [last email from me to client...] hi [client], based on this reply, and your demonstrated unwillingness to compromise/give any ground on issues at hand, i have decided to place your project on-hold for the moment i will be considering further options on how to over-come our challenges over the next few days i will contact you by monday 17/may to discuss any new options i have come up with, and if i believe it is appropriate to restart work on your project at that point or not told you it was long... what do you think?

• EntityManager injection works in JBoss 7.1.1 but not WebSphere 7

  - by BikerJared

  I've built an EJB that will manage my database access. I'm building a web app around it that uses Struts 2. The problem I'm having is when I deploy the ear, the EntityManager doesn't get injected into my service class (and winds up null and results in NullPointerExceptions). The weird thing is, it works on JBoss 7.1.1 but not on WebSphere 7. You'll notice that Struts doesn't inject the EJB, so I've got some intercepter code that does that. My current working theory right now is that the WS7 container can't inject the EntityManager because of Struts for some unknown reason. My next step is to try Spring next, but I'd really like to get this to work if possible. I've spent a few days searching and trying various things and haven't had any luck. I figured I'd give this a shot. Let me know if I can provide additional information. <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence"

• DropDownList Value not changing with UpdatePanel and ModalPopupExtender

  - by Richard

  Greetings, I have an asp.net webpage with an modalpopupextender inside of an updatepanel. When I click Ok on the popup, I can get the textbox values from the popup just fine, but the DropDownLists have the old/default value, not the new value I have selected for them. All the controls on the popup are set to enableviewstate = true, and autopostback = false (I just want to make the trip to the server when I click the ok button, not every time I change the value of the popups). Here is the relevant code. ========================== Client Side <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:Panel ID="EditIssuePanel" runat="server" CssClass="modalPopup" Style="display:block;" > <table style="width:500px;"> <tr style="height:50px;"> <td colspan="2" align="center"> <asp:Label ID="lblEditIssueHeader" runat="server" Text="Edit Issue"></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblIssueName" runat="server" Text="Name:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtName" runat="server" Width="250px" MaxLength="50"></asp:TextBox> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblDescription" runat="server" Text="Description:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtDescription" runat="server" Width="250px" MaxLength="1000"></asp:TextBox> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblType" runat="server" Text="Type:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlType" runat="server"> <asp:ListItem Selected="True" Value="B">Bug</asp:ListItem> <asp:ListItem Value="R">Request</asp:ListItem> <asp:ListItem Value="O">Other</asp:ListItem> </asp:DropDownList> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblStatus" runat="server" Text="Status:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlStatus" runat="server"> <asp:ListItem Selected="True" Value="L">Logged</asp:ListItem> <asp:ListItem Value="I">In Process</asp:ListItem> <asp:ListItem Value="C">Complete</asp:ListItem> </asp:DropDownList> &nbsp; </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblPriority" runat="server" Text="Priority:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlPriority" runat="server" EnableViewState="true" AutoPostBack="false"> <asp:ListItem Selected="True" Value="L">Low</asp:ListItem> <asp:ListItem Value="M">Medium</asp:ListItem> <asp:ListItem Value="H">High</asp:ListItem> </asp:DropDownList> &nbsp;</td> </tr> <tr style="height:30px"> <td class="labelscolumn">Logger</td> <td class="datacolumn"> <asp:Label ID="lblEnteredByClientUserID" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblDateResolutionRequested" runat="server" Text="Requested Complete Date:"></asp:Label> </td> <td class="datacolumn"> <igsch:WebDateChooser ID="wdcRequestCompleteDate" runat="server"> </igsch:WebDateChooser> &nbsp;</td> </tr> <tr style="height:30px"> <td class="labelscolumn">Logged Date</td> <td class="datacolumn"> <asp:Label ID="lblLoggedDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px"> <td class="labelscolumn">In Process Date</td> <td class="datacolumn"> <asp:Label ID="lblInProcessDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px"> <td class="labelscolumn">Resolved Date</td> <td class="datacolumn"> <asp:Label ID="lblResolvedDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn" valign="top"> <asp:Label ID="lblEmailCCList" runat="server" Text="Email CC:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtEmailCCList" runat="server" MaxLength="2000" Rows="0" TextMode="MultiLine" Height="83px" Width="250px"></asp:TextBox> &nbsp;</td> </tr> <tr> <td> <asp:Label ID="lblIssueID" runat="server" Text="" Visible="false"></asp:Label> <asp:Label ID="lblClientID" runat="server" Text="" Visible="false"></asp:Label> </td> <td align="right"> <asp:Button ID="btnEditOk" runat="server" Text="Ok" onclick="btnEditOk_Click"/>&nbsp;&nbsp; <asp:Button ID="btnEditCancel" runat="server" Text="Cancel" onclick="btnEditCancel_Click" />&nbsp;&nbsp;&nbsp;&nbsp; </td> </tr> </table> </asp:Panel> . . .

• Can this PHP version of SPICE be improved?

  I do not know much about PHP's standard library of functions and was wondering if the following code can be improved in any way.

• data is not inserting in my db table [closed]

  - by Sarojit Chakraborty

  Please see my below(SubjectDetailsDao.java) code of addZoneToDb method. My debugger is nicely running upto ** session.getTransaction().commit();** code. but after that debugger stops,I do not know why it stops after that line? .And because of this i am unable to insert my data into my database table. I don't know what to do.Why it is not inserting my data into my database table? Plz help me for this. H Now i am getting this Error: Struts Problem Report Struts has detected an unhandled exception: Messages: org.hibernate.event.PreInsertEvent.getSource()Lorg/hibernate/event/EventSource; File:

• ClickOnce manifest problem

  - by TWith2Sugars

  We are currently deploying a WPF 4 app via click once and there is a scenario when the installation fails. If the user does not have .Net 4.0 Full install and attempts to install our app the framework installs fine but the app fails to install. If we re-run the installation again the app installs fine. Here is a copy of the log: PLATFORM VERSION INFO Windows : 6.1.7600.0 (Win32NT) Common Language Runtime : 2.0.50727.4927 System.Deployment.dll : 2.0.50727.4927 (NetFXspW7.050727-4900) mscorwks.dll : 2.0.50727.4927 (NetFXspW7.050727-4900) dfdll.dll : 2.0.50727.4927 (NetFXspW7.050727-4900) dfshim.dll : 4.0.31106.0 (Main.031106-0000) SOURCES Deployment url : [URL REMOVED] Server : Apache/2.0.54 Application url : [URL REMOVED] Server : Apache/2.0.54 IDENTITIES Deployment Identity : Graphicly.App.application, Version=0.3.2.0, Culture=neutral, PublicKeyToken=c982228345371fbc, processorArchitecture=msil Application Identity : Graphicly.App.exe, Version=0.3.2.0, Culture=neutral, PublicKeyToken=c982228345371fbc, processorArchitecture=msil, type=win32 APPLICATION SUMMARY * Installable application.

• Setting int more than once causes crash

  - by JulianB

  I'm doing a CABasicAnimation and getting the value from a nested NSMutableArray. Everything is great the first time it runs but crashes when called again either with custom functions or viewDidLoad. I've isolated it down to this line int int1 = [[[locationsArray objectAtIndex:0] objectAtIndex:0 ]integerValue] ; I assume it's to do with int not being a pointer but I'm lost as have to get the value without crashing the second time around Process: CEO Report 2011 [61880] Path: /Users/julian/Library/Application Support/iPhone Simulator/4.2/Applications/03CFB7BC-0722-4CA0-9E7D-39772AEEF444/CEO Report 2011.app/CEO Report 2011 Identifier: CEO Report 2011 Version: ???

• Dynamic DataGrid columns in WPF DataGrid based on the underlying set of data (and their type)

  - by StatsMan

  Hello everyone, I've got kind of a conceptual question. I am in the process of wrapping some statistics classes I wrote into WPF. For that I have two DataGrid(-Views, currently in WinForms). In one DataGrid each row represents a column in the other. There I can set-up different variables (as in mathematical/statistical variables) with fields like "Header", "DataType", "ValidationBehaviour", "DisplayType". There I can also set-up how it should be displayed. Some Columns can automatically be set to ComboBoxColumns, some TextBoxColumns, and so on and so forth. So, now once I've set-up these Columns I can go to the other grid and enter my data. I may, for instance, have generated (in grid 1) one Column called "Annual Gross Salary" with input of numerical values. Another Column called "Education" with "0=NoEducation", "1=College Level", "3=Universitary" etc. These labels are displayed as text in the combobox and my statistics engine behind then selects the respective value (0-3) for calculations (i.e. ordinal, nominal variables). Sooo. In WinForms I could basically generate all the columns by hand in code and then add my data in the respective cells/rows. Now in WPF I thought that must be easy to realise. However, yesterday I got started with ICustomPropertyDescriptor which (maybe I was too thick) didn't give me the results I was looking for. Basically, I just need to be able to dynamically generate columns (and rows) with different Layout, Controls (ComboBox, simple Input, DateTimes) based on the data that I have. But I don't really know how to go about it? So here in summary: DataGrid 1 Purpose is to display columns that have been specified in DataGrid 2 In rows, the user can add any kind of data in the rows below the columns that is allowed as to the columns specifications DataGrid 2 Each row in this grid represents a column in DataGrid 1 Contains fields like Name/Header, DataType, Validation Behaviour, Default Value, Data Formatting, etc. Also contains a function to be able to set-up how it should be displayed. The user can select from, for instance, ComboBoxColumn (and also add the available options), DateTime, normal TextBox, CheckBox etc. After finishing adding a row it will automatically appear as a new column in DataGrid 1 I'd appreciate any kind of pointer into the right direction. Thanks very, very much in advance! :)

• WPF MVVM Trigger Animation on MainWindow close

  - by Scott

  I'm using trying to implement MVVM in my app. I have a MainWindow.xaml and a MainWindowViewModel. I'm in the process of removing all of the code-behind code from the MainWindow.xaml but I'm stuck on one final piece. In my pre-MVVM setup I started an animation in the MainWindow.xaml.cs that would fade out the form before closing it. Since Closing is not a RoutedEvent, I had to use code-behind to get this to work. My VM has the following two properties that can be bound: ClosingWindow and CloseWindow. My goal was to bind a DataTrigger in my MainWindowStyle to the ClosingWindow property of the VM. When ClosingWindow was set to True, it would start an animation using the following XAML: <DataTrigger Binding="{Binding ClosingWindow}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0" Duration="0:0:2"/> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> Somehow (insert magic here) I was going to set CloseWindow on the VM, via Binding, to True when the animation completed, which would then use an AttachedBehavior to Close the Window. The AttachedBehavior works perfectly when I just set CloseWindow directly using the following XAML: <DataTrigger Binding="{Binding CloseWindow}" Value="True"> <Setter Property="ab:WindowCloseBehavior.Close" Value="True"/> </DataTrigger> ...but I want to reproduce the form fade before the form actually closes. So there are two issues that I've run into: First, the animation doesn't work. I enter the trigger correctly (I've taken out the animation and put a Setter statement in there that changes the Title of the MainWindow to "Closing" and it changes correctly when ClosingWindow = True) but the DoubleAnimation never does anything. Second, there's no way to set the value of CloseWindow once the animation is complete. I looked at Marlon Grech's animation code but that won't work on DataTriggers. I can't publish a RoutedEvent because my VM doesn't descend from UIElement, and I've been Googling all day trying to come up with a clever, MVVM-friendly way to do this with no luck. So any ideas why that animation doesn't do anything? And more importantly, how would you solve the entire problem of animating a form fade on close from the VM? I don't doubt that my entire solution to this problem might be whacked so I'm open to just about anything.
