Long lines of text in source code [closed]

- by ale

Possible Duplicate: Is the 80 character limit still relevant in times of widescreen monitors? I used to set a vertical line set at 80 characters in my text editor and then I added carriage returns if the lines got too long. I later increased the value to 135 characters. I started using word wrap and not giving myself a limit but tried to keep lines short if I could because it took a lot of time shortening my lines. People at work use word wrap and don't give themselves a limit.. is this the correct way? What are you meant to do ? Many thanks.

Print out the amount of times 2 words appear in the syslog. But also have it tell me how many times for each hour

- by wolfspinone

So I'm trying to create a bash script that looks for two words in my syslog file. Then I want the script to print out how many times those two words have appeared. Also I want it to print it out for every hour of the day. So like if the word dog appeared 4 times during the first hour of today, it says Hour one, dog 4. Finally at the end of the script I want it to print out how many times those words appeared all day. The sudo code I have thus far is if 2 > hour find permit find block print both finish if 1 < hour < 2 find permit find block print both finish if 2 < hour < 3 find permit find block print both finish command is grep -o "\WORD\" Syslog.txt * | sort | uniq -c

Clicking Elements in Android Doesn't Display the Correct Values

- by Devin

I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment. I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value). There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code: package com.TicTacToe.app; import com.TicTacToe.app.R; //Other import statements public class TicTacToe extends Activity { public String player = "X"; public int ALERT_ID; public int buttonId; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //Sets up instances of UI elements final TextView playerText = (TextView)findViewById(R.id.CurrentPlayerDisp); final Button button = (Button) findViewById(R.id.SetPlayer); final TextView location1 = (TextView)findViewById(R.id.location1); final TextView location2 = (TextView)findViewById(R.id.location2); final TextView location3 = (TextView)findViewById(R.id.location3); final TextView location4 = (TextView)findViewById(R.id.location4); final TextView location5 = (TextView)findViewById(R.id.location5); final TextView location6 = (TextView)findViewById(R.id.location6); final TextView location7 = (TextView)findViewById(R.id.location7); final TextView location8 = (TextView)findViewById(R.id.location8); final TextView location9 = (TextView)findViewById(R.id.location9); playerText.setText(player); //Handlers for events button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // Perform action on click if (player.equals("X")){ player = "O"; playerText.setText(player); } else if(player.equals("O")){ player = "X"; playerText.setText(player); } //Sets up the dialog buttonId = 0; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 1; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 2; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 3; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 4; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location5.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 5; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location6.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 6; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location7.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 7; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location8.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 8; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location9.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 9; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); } protected Dialog onCreateDialog(int id){ String msgString = "You are on spot " + buttonId; AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(msgString) .setCancelable(false) .setNeutralButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); return alert; } }

Are there any CMS editors out there which users can populate locked down HTML templates with content

- by Deep

Hi there, We work in email marketing, creating HTML/TEXT emails for clients. In essence we design HTML email templates for our clients. Clients then post us content (via a form) to populate these templates before we send them out. Right now we do this manually, basically cutting and pasting the content from their submitted form into the relevant parts of the template, which is time consuming and particularly mind-numbing. What we're looking for (and have so far been unable to find) is a simple system which will allow us to capture this client content in a sort of WYSIWYG HTML format. Basically they populate a locked down version of the template, entering text where necessary, before submitting to us. This is our most basic requirement, and a friend of mine kindly demo'd a proof of concept here: http://advantageone.co.uk/mbe/ Note: If you click on a text area in the body of the template, an editor pop ups. Now what we are looking for a CMS editor out there which can be easily adapted to do the above and the following for our end clients? User login View previously submitted campaigns that they have created and edit these Create new - selecting from template (assigned to their user/client id), perhaps being able to add new rows to the template. And have these HTML templates locked down so they can only edit what they're allowed too (like in the demo above), and perhaps make some areas required. Perhaps have a simple workflow or approval built in Allow us to lock submitted campaigns after a point so they can't be further edited, and as administrators view all campaigns from all users Be so incredibly simple, with any extraneous functionality switched off Essentially an extremley simple stripped down CMS, but we use the outputted HTML for sending out as an email, rather than publishing onto the web. Now to the actual dilemma: we're looking for something really simple, and the above sounds like a CMS. But we haven't been able to find anything that already does, or can be easily adapted to do this. Everything is either too complex, or simple and inflexible. We're sure there must be something off the shelf available, rather than us coding something ourselves. But we've kind of got stuck. Does anyone know of a system, or could recommend a system that can do the above out of the box, or with a few days tweaking? Forgive me if this is a little disjointed, if I'm being incredibly dopey and there is something out there please let me know! Kind regards, Dp.

What makes a language (or feature) "hackerish"?

- by iCanLearn

I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

What are the Rails best practices for javascript templates in restful/resourceful controllers?

- by numbers1311407

First, 2 common (basic) approaches: # returning from some FoosController method respond_to do |format| # 1. render the javascript directly format.js { render :json => @foo.to_json } # 2. render the default template, say update.js.erb format.js { render } end # in update.js.erb $('#foo').html("<%= escape_javascript(render(@foo)) %>") These are obviously simple cases but I wanted to illustrate what I'm talking about. I believe that these are also the cases expected by the default responder in rails 3 (either the action-named default template or calling to_#{format} on the resource.) The Issues With 1, you have total flexibility on the view side with no worries about the template, but you have to manipulate the DOM directly via javascript. You lose access to helpers, partials, etc. With 2, you have partials and helpers at your disposal, but you're tied to the one template (by default at least). All your views that make JS calls to FoosController use the same template, which isn't exactly flexible. Three Other Approaches (none really satisfactory) 1.) Escape partials/helpers I need into javascript beforehand, then inserting them into the page after, using string replacement to tailor them to the results returned (subbing in name, id, etc). 2.) Put view logic in the templates. For example, looking for a particular DOM element and doing one thing if it exists, another if it does not. 3.) Put logic in the controller to render different templates. For example, in a polymorphic belongs to where update might be called for either comments/foo or posts/foo, rendering commnts/foos/update.js.erb versus posts/foos/update.js.erb. I've used all of these (and probably others I'm not thinking of). Often in the same app, which leads to confusing code. Are there best practices for this sort of thing? It seems like a common enough use-case that you'd want to call controllers via Ajax actions from different views and expect different things to happen (without having to do tedious things like escaping and string-replacing partials and helpers client side). Any thoughts?

sound cuts out at random times

- by jayb151

Since I updated to 14.04, I have been having a problem with my sound. Every once in a while it "skips a beat." and when I say every once in a while, I mean 2-4 times a minute. It's literally that the sounds goes a way for about half a second. It doesn't pick up where it left off, but rather continues from where it should be...if that makes sense. So, if it cut in mid word, I wouldn't hear the end of the word. I didn't have this problem before I updated from 12.04. There is no popping or static, it just cuts for a fraction of a second. Any thoughts? Thanks!

Reading Data from DDFS ValueError: No JSON object could be decoded

- by secumind

I'm running dozens of map reduce jobs for a number of different purposes using disco. My data has grown enormous and I thought I would try using DDFS for a change rather than standard txt files. I've followed the DISCO map/reduce example Counting Words as a map/reduce job, without to much difficulty and with the help of others, Reading JSON specific data into DISCO I've gotten past one of my latest problems. I'm trying to read data in/out of ddfs to better chunk and distribute it but am having a bit of trouble.

Nagios notifications definitions

- by Colin

I am trying to monitor a web server in such a way that I want to search for a particular string on a page via http. The command is defined in command.cfg as follows # 'check_http-mysite command definition' define command { command_name check_http-mysite command_line /usr/lib/nagios/plugins/check_http -H mysite.example.com -s "Some text" } # 'notify-host-by-sms' command definition define command { command_name notify-host-by-sms command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$ :Host$HOSTALIAS$ is $HOSTSTATE$ ($OUTPUT$)" } # 'notify-service-by-sms' command definition define command { command_name notify-service-by-sms command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ ($OUTPUT$)" } Now if nagios doesn't find "Some text" on the home page mysite.example.com, nagios should notify a contact via sms through the Clickatell http API which I have a script for that that I have tested and found that it works fine. Whenever I change the command definition to search for a string which is not on the page, and restart nagios, I can see on the web interface that the string was not found. What I don't understand is why isn't the notification sent though I have defined the host, hostgroup, contact, contactgroup and service and so forth. What I'm I missing, these are my definitions, In my web access through the cgi I can see that I have notifications have been defined and enabled though I don't get both email and sms notifications during hard status changes. host.cfg define host { use generic-host host_name HAL alias IBM-1 address xxx.xxx.xxx.xxx check_command check_http-mysite } *hostgroups_nagios2.cfg* # my website define hostgroup{ hostgroup_name my-servers alias All My Servers members HAL } *contacts_nagios2.cfg* define contact { contact_name colin alias Colin Y service_notification_period 24x7 host_notification_period 24x7 service_notification_options w,u,c,r,f,s host_notification_options d,u,r,f,s service_notification_commands notify-service-by-email,notify-service-by-sms host_notification_commands notify-host-by-email,notify-host-by-sms email [email protected] pager +254xxxxxxxxx } define contactgroup{ contactgroup_name site_admin alias Site Administrator members colin } *services_nagios2.cfg* # check for particular string in page via http define service { hostgroup_name my-servers service_description STRING CHECK check_command check_http-mysite use generic-service notification_interval 0 ; set > 0 if you want to be renotified contacts colin contact_groups site_admin } Could someone please tell me where I'm going wrong. Here are the generic-host and generic-service definitions *generic-service_nagios2.cfg* # generic service template definition define service{ name generic-service ; The 'name' of this service template active_checks_enabled 1 ; Active service checks are enabled passive_checks_enabled 1 ; Passive service checks are enabled/accepted parallelize_check 1 ; Active service checks should be parallelized (disabling this can lead to major performance problems) obsess_over_service 1 ; We should obsess over this service (if necessary) check_freshness 0 ; Default is to NOT check service 'freshness' notifications_enabled 1 ; Service notifications are enabled event_handler_enabled 1 ; Service event handler is enabled flap_detection_enabled 1 ; Flap detection is enabled failure_prediction_enabled 1 ; Failure prediction is enabled process_perf_data 1 ; Process performance data retain_status_information 1 ; Retain status information across program restarts retain_nonstatus_information 1 ; Retain non-status information across program restarts notification_interval 0 ; Only send notifications on status change by default. is_volatile 0 check_period 24x7 normal_check_interval 5 retry_check_interval 1 max_check_attempts 4 notification_period 24x7 notification_options w,u,c,r contact_groups site_admin register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE! } *generic-host_nagios2.cfg* define host{ name generic-host ; The name of this host template notifications_enabled 1 ; Host notifications are enabled event_handler_enabled 1 ; Host event handler is enabled flap_detection_enabled 1 ; Flap detection is enabled failure_prediction_enabled 1 ; Failure prediction is enabled process_perf_data 1 ; Process performance data retain_status_information 1 ; Retain status information across program restarts retain_nonstatus_information 1 ; Retain non-status information across program restarts max_check_attempts 10 notification_interval 0 notification_period 24x7 notification_options d,u,r contact_groups site_admin register 1 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE! }

Creating a Build Definition using the TFS 2010 API

- by Jakob Ehn

In this post I will show how to create a new build definition in TFS 2010 using the TFS API. When creating a build definition manually, using Team Explorer, the necessary steps are lined out in the New Build Definition Wizard: So, lets see how the code looks like, using the same order. To start off, we need to connect to TFS and get a reference to the IBuildServer object: TfsTeamProjectCollection server = newTfsTeamProjectCollection(newUri("http://<tfs>:<port>/tfs")); server.EnsureAuthenticated(); IBuildServer buildServer = (IBuildServer) server.GetService(typeof (IBuildServer)); General First we create a IBuildDefinition object for the team project and set a name and description for it: var buildDefinition = buildServer.CreateBuildDefinition(teamProject); buildDefinition.Name = "TestBuild"; buildDefinition.Description = "description here..."; Trigger Next up, we set the trigger type. For this one, we set it to individual which corresponds to the Continuous Integration - Build each check-in trigger option buildDefinition.ContinuousIntegrationType = ContinuousIntegrationType.Individual; Workspace For the workspace mappings, we create two mappings here, where one is a cloak. Note the user of $(SourceDir) variable, which is expanded by Team Build into the sources directory when running the build. buildDefinition.Workspace.AddMapping("$/Path/project.sln", "$(SourceDir)", WorkspaceMappingType.Map); buildDefinition.Workspace.AddMapping("$/OtherPath/", "", WorkspaceMappingType.Cloak); Build Defaults In the build defaults, we set the build controller and the drop location. To get a build controller, we can (for example) use the GetBuildController method to get an existing build controller by name: buildDefinition.BuildController = buildServer.GetBuildController(buildController); buildDefinition.DefaultDropLocation = @\\SERVER\Drop\TestBuild; Process So far, this wasy easy. Now we get to the tricky part. TFS 2010 Build is based on Windows Workflow 4.0. The build process is defined in a separate .XAML file called a Build Process Template. By default, every new team team project containtwo build process templates called DefaultTemplate and UpgradeTemplate. In this sample, we want to create a build definition using the default template. We use te QueryProcessTemplates method to get a reference to the default for the current team project //Get default template var defaultTemplate = buildServer.QueryProcessTemplates(teamProject).Where(p => p.TemplateType == ProcessTemplateType.Default).First(); buildDefinition.Process = defaultTemplate; There are several build process templates that can be set for the default build process template. Only one of these are required, the ProjectsToBuild parameters which contains the solution(s) and configuration(s) that should be built. To set this info, we use the ProcessParameters property of thhe IBuildDefinition interface. The format of this property is actually just a serialized dictionary (IDictionary<string, object>) that maps a key (parameter name) to a value which can be any kind of object. This is rather messy, but fortunately, there is a helper class called WorkflowHelpers inthe Microsoft.TeamFoundation.Build.Workflow namespace, that simplifies working with this persistence format a bit. The following code shows how to set the BuildSettings information for a build definition: //Set process parameters varprocess = WorkflowHelpers.DeserializeProcessParameters(buildDefinition.ProcessParameters); //Set BuildSettings properties BuildSettings settings = newBuildSettings(); settings.ProjectsToBuild = newStringList("$/pathToProject/project.sln"); settings.PlatformConfigurations = newPlatformConfigurationList(); settings.PlatformConfigurations.Add(newPlatformConfiguration("Any CPU", "Debug")); process.Add("BuildSettings", settings); buildDefinition.ProcessParameters = WorkflowHelpers.SerializeProcessParameters(process); The other build process parameters of a build definition can be set using the same approach Retention Policy This one is easy, we just clear the default settings and set our own: buildDefinition.RetentionPolicyList.Clear(); buildDefinition.AddRetentionPolicy(BuildReason.Triggered, BuildStatus.Succeeded, 10, DeleteOptions.All); buildDefinition.AddRetentionPolicy(BuildReason.Triggered, BuildStatus.Failed, 10, DeleteOptions.All); buildDefinition.AddRetentionPolicy(BuildReason.Triggered, BuildStatus.Stopped, 1, DeleteOptions.All); buildDefinition.AddRetentionPolicy(BuildReason.Triggered, BuildStatus.PartiallySucceeded, 10, DeleteOptions.All); Save It! And we’re done, lets save the build definition: buildDefinition.Save(); That’s it!

Dependency Replication with TFS 2010 Build

- by Jakob Ehn

Some time ago, I wrote a post about how to implement dependency replication using TFS 2008 Build. We use this for Library builds, where we set up a build definition for a common library, and have the build check the resulting assemblies back into source control. The folder is then branched to the applications that need to reference the common library. See the above post for more details. Of course, we have reimplemented this feature in TFS 2010 Build, which results in a much nicer experience for the developer who wants to setup a new library build. Here is how it looks: There is a separate build process template for library builds registered in all team projects The following properties are used to configure the library build: Deploy Folder in Source Control is the server path where the assemblies should be checked in DeploymentFiles is a list of files and/or extensions to what files to check in. Default here is *.dll;*.pdb which means that all assemblies and debug symbols will be checked in. We can also type for example CommonLibrary.*;SomeOtherAssembly.dll in order to exclude other assemblies You can also see that we are versioning the assemblies as part of the build. This is important, since the resulting assemblies will be deployed together with the referencing application. When the build executes, it will see of the matching assemblies exist in source control, if not, it will add the files automatically: After the build has finished, we can see in the history of the TestDeploy folder that the build service account has in fact checked in a new version: Nice! The implementation of the library build process template is not very complicated, it is a combination of customization of the build process template and some custom activities. We use the generic TFActivity (http://geekswithblogs.net/jakob/archive/2010/11/03/performing-checkins-in-tfs-2010-build.aspx) to check in and out files, but for the part that checks if a file exists and adds it to source control, it was easier to do this in a custom activity: public sealed class AddFilesToSourceControl : BaseCodeActivity { // Files to add to source control [RequiredArgument] public InArgument<IEnumerable<string>> Files { get; set; } [RequiredArgument] public InArgument<Workspace> Workspace { get; set; } // If your activity returns a value, derive from CodeActivity<TResult> // and return the value from the Execute method. protected override void Execute(CodeActivityContext context) { foreach (var file in Files.Get(context)) { if (!File.Exists(file)) { throw new ApplicationException("Could not locate " + file); } var ws = this.Workspace.Get(context); string serverPath = ws.TryGetServerItemForLocalItem(file); if( !String.IsNullOrEmpty(serverPath)) { if (!ws.VersionControlServer.ServerItemExists(serverPath, ItemType.File)) { TrackMessage(context, "Adding file " + file); ws.PendAdd(file); } else { TrackMessage(context, "File " + file + " already exists in source control"); } } else { TrackMessage(context, "No server path for " + file); } } } } This build template is a very nice tool that makes it easy to do dependency replication with TFS 2010. Next, I will add funtionality for automatically merging the assemblies (using ILMerge) as part of the build, we do this to keep the number of references to a minimum.

jQuery Templates on Microsoft Ajax CDN

- by Stephen Walther

The beta version of the jQuery Templates plugin is now hosted on the Microsoft Ajax CDN. You can start using the jQuery Templates plugin in your application by referencing both jQuery 1.4.2 and jQuery Templates from the CDN. Here are the two script tags that you will want to use when developing an application: <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js”></script> <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.js”></script> In addition, minified versions of both files are available from the CDN: <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> Here’s a full code sample of using jQuery Templates from the CDN to display pictures of cats from Flickr: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Cats</title> <style type="text/css"> html { background-color:Orange; } #catBox div { width:250px; height:250px; border:solid 1px black; background-color:White; margin:5px; padding:5px; float:left; } #catBox img { width:200px; height: 200px; } </style> </head> <body> <h1>Cat Photos!</h1> <div id="catBox"></div> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> <script id="catTemplate" type="text/x-jquery-tmpl"> <div> <b>${title}</b> <br /> <img src="${media.m}" /> </div> </script> <script type="text/javascript"> var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); </script> </body> </html> This page displays a list of cats retrieved from Flickr: Notice that the cat pictures are retrieved and rendered with just a few lines of code: var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); The final line of code, the one that calls the tmpl() method, uses the Templates plugin to render the cat photos in a template named catTemplate. The catTemplate template is contained within a SCRIPT element with type="text/x-jquery-tmpl". The jQuery Templates plugin is an “official” jQuery plugin which will be included in jQuery 1.5 (the next major release of jQuery). You can read the full documentation for the plugin at the jQuery website: http://api.jquery.com/category/plugins/templates/ The jQuery Templates plugin is still beta so we would really appreciate your feedback on the plugin. Let us know if you use the Templates plugin in your website.

Announcing the ASP.NET and Web Tools 2012.2 Release Candidate

- by ScottGu

This week the ASP.NET and Visual Web Developer teams delivered the Release Candidate of the ASP.NET and Web Tools 2012.2 update (formerly ASP.NET Fall 2012 Update BUILD Prerelease). This update extends the existing ASP.NET runtime and adds new web tooling to Visual Studio 2012. Whether you use Web Forms, MVC, Web API, or any other ASP.NET technology, there is something cool in this update for you. You can download and install the RC today: http://www.asp.net/vnext. Great ASP.NET Enhancements This update adds new ASP.NET templates and features, including: New ASP.NET MVC templates. Creating Facebook applications just became easier using the new Facebook Application template. In just a few easy steps you can create a Facebook application that gets data from the logged in user as well as integrates with their friends. A new Single Page Application template allows developers to build interactive client-side web apps using Knockout, jQuery, and ASP.NET Web API. Real-time communication support with ASP.NET SignalR. This enables you to easily take advantage of the new WebSocket support in .NET 4.5, while also automatically degrading to long-polling and other protocols for older clients. If you haven’t tried SignalR yet you should – it is awesome. New ASP.NET Web API functionality, including support for OData, integrated tracing, and automatically generating help page documentation for your API. New ASP.NET Friendly URL functionality. This new feature makes it very easy for Web Forms developers to generate cleaner looking URLs (without the .aspx extension). The Friendly URLs feature also makes it easier for developers to add mobile support to their applications with support for mobile .ASPX pages and supporting switching between desktop and mobile views. It can be used with existing ASP.NET v4.0 applications. Visual Studio 2012 Web publishing enhancements. Web site projects now have the same publish experience as web application projects (including to Windows Azure Web Sites), and you can selectively publish files, see the differences between local and remote files, and update local to remote files or vice versa. Visual Studio 2012 Page Inspector enhancements. JavaScript selection mapping is now supported, and you can CSS updates in real-time. Visual Studio 2012 editor support for Knockout IntelliSense and pasting JSON as a .NET class (which makes it even easier to consume Web APIs from others). Visual Studio 2012 Project Template updates, including the latest versions of jQuery, jQuery UI, jQuery Validation, Modernirz, Knockout and more… How it is delivered You can download and install an integrated setup that contains the above enhancements today from http://www.asp.net/vnext. The new runtime functionality is delivered to ASP.NET via additional NuGet packages. This means that installing this update does not make any changes to the existing ASP.NET binaries, and thus does not cause any compatibility issues with existing projects. New projects will contain the new functionality and existing projects can be updated with the new NuGet packages. Summary Web development is changing, and ASP.NET is rapidly delivering new capabilities to developers that help them take full advantage of new capabilities. The ASP.NET and Web Tools 2012.2 update installs in minutes without altering the current ASP.NET run time components. For a complete description see the Release Notes. Next week I plan to publish a tutorial showing how to build a cool Facebook application using the new Facebook template. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

Combining Scrum, TFS2010 and Email to keep everyone in the loop

- by Martin Hinshelwood

Often you will receive rich information from your Product Owner (Customer) about tasks. That information can be in the form of Word documents, HTML Emails and Pictures, but you generally receive them in the context of an Email. You need to keep these so your Team can refer to it later, and so you can send a “done” when the task has been completed. This preserves the “history” of the task and allows you to keep relevant partied included in any future conversation. At SSW we keep the original email so that we can reply Done and delete the email. But keeping it in your email does not help other members of the team if they complete the task and need to send the “done”. Worse yet, the description field in Team Foundation Server 2010 (TFS 2010) does not support HTML and images, nor does the default task template support an “interested parties” or CC field. You can attach this content manually, but it can be time consuming. Figure: Description only supports plain text, and History supports HTML with no images What should we do? At SSW we always follow the rules, and it just so happened that we have rules to both achieve this, and to make it easier. You should follow the existing Rules to Better Project Management and attach the email to your task so you can refer to and reply to it later when you close the task: Do you know what Outlook add-ins you need? Describe the work item request in an email Use Outlook Add-in to move the email to a TFS Work Item When replying to an email with “done” you should follow: Do you update Team Companion template, so the email "subject" doesn't change? Do you update Team Companion template, so you can generate a proper "done" mail? Following these simple rules will help your Product Owner understand you better, and allow your team to more effectively collaborate with each other. An added bonus is that as we are keeping the email history in sync with TFS. When you “reply all” to the email all of the interested partied to the Task are also included. This notified those that may have been blocked by your task to keep up to date with its status. This has been published as Do you know to ensure that relevant emails are attached to tasks in our Rules to Better Scrum using TFS. What could we do better? I would like to see this process automated so that we capture the information correctly in the task without the need to use email. This would require a change to the process template in Team Foundation Server to add an “Interested Parties” field. Each reply to the email would need to be automatically processed into a Work Item. This could be done by adding a task identifier as the first item in the “Relates to” email header, and copying in an email address that you watch. This would then parse out the relevant information and add the new message to the history, update the “Interested parties” field and attach the Images. Upon reflection, it may even be possible, but more difficult to do this using ONLY the History field and including some of the header information in there to the build a done email with history. This would not currently deal with email “forks” well, but I think it would be adequate for our needs. It would be nice if we could find time to implement this, but currently it is but a pipe dream. Maybe Microsoft could implement something in the next version of Team Foundation Server, and in the mean time we have a process that works well. Technorati Tags: Scrum,SSW Rules,TFS 2010,TFS 2008

Creating shapes on the fly

- by Bertrand Le Roy

Most Orchard shapes get created from part drivers, but they are a lot more versatile than that. They can actually be created from pretty much anywhere, including from templates. One example can be found in the Layout.cshtml file of the ThemeMachine theme: WorkContext.Layout.Footer .Add(New.BadgeOfHonor(), "5"); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } What this is really doing is create a new shape called BadgeOfHonor and injecting it into the Footer global zone (that has not yet been defined, which in itself is quite awesome) with an ordering rank of "5". We can actually come up with something simpler, if we want to render the shape inline instead of sending it into a zone: @Display(New.BadgeOfHonor()) Now let's try something a little more elaborate and create a new shape for displaying a date and time: @Display(New.DateTime(date: DateTime.Now, format: "d/M/yyyy")) For the moment, this throws a "Shape type DateTime not found" exception because the system has no clue how to render a shape called "DateTime" yet. The BadgeOfHonor shape above was rendering something because there is a template for it in the theme: Themes/ThethemeMachine/Views/BadgeOfHonor.cshtml. We need to provide a template for our new shape to get rendered. Let's add a DateTime.cshtml file into our theme's Views folder in order to make the exception go away: Hi, I'm a date time shape. Now we're just missing one thing. Instead of displaying some static text, which is not very interesting, we can display the actual time that got passed into the shape's dynamic constructor. Those parameters will get added to the template's Model, so they are easy to retrieve: @(((DateTime)Model.date).ToString(Model.format)) Now that may remind you a little of WebForm's user controls. That's a fair comparison, except that these shapes are much more flexible (you can add properties on the fly as necessary), and that the actual rendering is decoupled from the "control". For example, any theme can override the template for a shape, you can use alternates, wrappers, etc. Most importantly, there is no lifecycle and protocol abstraction like there was in WebForms. I think this is a real improvement over previous attempts at similar things.

maintaining a growing, diverse codebase with continuous integration

- by Nate

I am in need of some help with philosophy and design of a continuous integration setup. Our current CI setup uses buildbot. When I started out designing it, I inherited (well, not strictly, as I was involved in its design a year earlier) a bespoke CI builder that was tailored to run the entire build at once, overnight. After a while, we decided that this was insufficient, and started exploring different CI frameworks, eventually choosing buildbot. One of my goals in transitioning to buildbot (besides getting to enjoy all the whiz-bang extras) was to overcome some of the inadequacies of our bespoke nightly builder. Humor me for a moment, and let me explain what I have inherited. The codebase for my company is almost 150 unique c++ Windows applications, each of which has dependencies on one or more of a dozen internal libraries (and many on 3rd party libraries as well). Some of these libraries are interdependent, and have depending applications that (while they have nothing to do with each other) have to be built with the same build of that library. Half of these applications and libraries are considered "legacy" and unportable, and must be built with several distinct configurations of the IBM compiler (for which I have written unique subclasses of Compile), and the other half are built with visual studio. The code for each compiler is stored in two separate Visual SourceSafe repositories (which I am simply handling using a bunch of ShellCommands, as there is no support for VSS). Our original nightly builder simply took down the source for everything, and built stuff in a certain order. There was no way to build only a single application, or pick a revision, or to group things. It would launched virtual machines to build a number of the applications. It wasn't very robust, it wasn't distributable. It wasn't terribly extensible. I wanted to be able to overcame all of these limitations in buildbot. The way I did this originally was to create entries for each of the applications we wanted to build (all 150ish of them), then create triggered schedulers that could build various applications as groups, and then subsume those groups under an overall nightly build scheduler. These could run on dedicated slaves (no more virtual machine chicanery), and if I wanted I could simply add new slaves. Now, if we want to do a full build out of schedule, it's one click, but we can also build just one application should we so desire. There are four weaknesses of this approach, however. One is our source tree's complex web of dependencies. In order to simplify config maintenace, all builders are generated from a large dictionary. The dependencies are retrieved and built in a not-terribly robust fashion (namely, keying off of certain things in my build-target dictionary). The second is that each build has between 15 and 21 build steps, which is hard to browse and look at in the web interface, and since there are around 150 columns, takes forever to load (think from 30 seconds to multiple minutes). Thirdly, we no longer have autodiscovery of build targets (although, as much as one of my coworkers harps on me about this, I don't see what it got us in the first place). Finally, aformentioned coworker likes to constantly bring up the fact that we can no longer perform a full build on our local machine (though I never saw what that got us, either, considering that it took three times as long as the distributed build; I think he is just paranoically phobic of ever breaking the build). Now, moving to new development, we are starting to use g++ and subversion (not porting the old repository, mind you - just for the new stuff). Also, we are starting to do more unit testing ("more" might give the wrong picture... it's more like any), and integration testing (using python). I'm having a hard time figuring out how to fit these into my existing configuration. So, where have I gone wrong philosophically here? How can I best proceed forward (with buildbot - it's the only piece of the puzzle I have license to work on) so that my configuration is actually maintainable? How do I address some of my design's weaknesses? What really works in terms of CI strategies for large, (possibly over-)complex codebases?

What is the right way to process inconsistent data files?

- by Tahabi

I'm working at a company that uses Excel files to store product data, specifically, test results from products before they are shipped out. There are a few thousand spreadsheets with anywhere from 50-100 relevant data points per file. Over the years, the schema for the spreadsheets has changed significantly, but not unidirectionally - in the sense that, changes often get reverted and then re-added in the space of a few dozen to few hundred files. My project is to convert about 8000 of these spreadsheets into a database that can be queried. I'm using MongoDB to deal with the inconsistency in the data, and Python. My question is, what is the "right" or canonical way to deal with the huge variance in my source files? I've written a data structure which stores the data I want for the latest template, which will be the final template used going forward, but that only helps for a few hundred files historically. Brute-forcing a solution would mean writing similar data structures for each version/template - which means potentially writing hundreds of schemas with dozens of fields each. This seems very inefficient, especially when sometimes a change in the template is as little as moving a single line of data one row down or splitting what used to be one data field into two data fields. A slightly more elegant solution I have in mind would be writing schemas for all the variants I can find for pre-defined groups in the source files, and then writing a function to match a particular series of files with a series of variants that matches that set of files. This is because, more often that not, most of the file will remain consistent over a long period, only marred by one or two errant sections, but inside the period, which section is inconsistent, is inconsistent. For example, say a file has four sections with three data fields, which is represented by four Python dictionaries with three keys each. For files 7000-7250, sections 1-3 will be consistent, but section 4 will be shifted one row down. For files 7251-7500, 1-3 are consistent, section 4 is one row down, but a section five appears. For files 7501-7635, sections 1 and 3 will be consistent, but section 2 will have five data fields instead of three, section five disappears, and section 4 is still shifted down one row. For files 7636-7800, section 1 is consistent, section 4 gets shifted back up, section 2 returns to three cells, but section 3 is removed entirely. Files 7800-8000 have everything in order. The proposed function would take the file number and match it to a dictionary representing the data mappings for different variants of each section. For example, a section_four_variants dictionary might have two members, one for the shifted-down version, and one for the normal version, a section_two_variants might have three and five field members, etc. The script would then read the matchings, load the correct mapping, extract the data, and insert it into the database. Is this an accepted/right way to go about solving this problem? Should I structure things differently? I don't know what to search Google for either to see what other solutions might be, though I believe the problem lies in the domain of ETL processing. I also have no formal CS training aside from what I've taught myself over the years. If this is not the right forum for this question, please tell me where to move it, if at all. Any help is most appreciated. Thank you.

Overriding the Pager rendering in Orchard

- by Bertrand Le Roy

The Pager shape that is used in Orchard to render pagination is one of those shapes that are built in code rather than in a Razor template. This can make it a little more confusing to override, but nothing is impossible. If we look at the Pager method in CoreShapes, here is what we see: [Shape] public IHtmlString Pager(dynamic Shape, dynamic Display) { Shape.Metadata.Alternates.Clear(); Shape.Metadata.Type = "Pager_Links"; return Display(Shape); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The Shape attribute signals a shape method. All it does is remove all alternates that may exist and replace the type of the shape with “Pager_Links”. In turn, this shape method is rather large and complicated, but it renders as a set of smaller shapes: a List with a “pager” class, and under that Pager_First, Pager_Previous, Pager_Gap, for each page a Pager_Link or a Pager_Current, then Pager_Gap, Pager_Next and Pager_Last. Each of these shapes can be displayed or not depending on the properties of the pager. Each can also be overridden with a Razor template. This can be done by dropping a file into the Views folder of your theme. For example, if you want the current page to appear between square braces, you could drop this Pager-CurrentPage.cshtml into your views folder: <span>[@Model.Value]</span> This overrides the original shape method, which was this: [Shape] public IHtmlString Pager_CurrentPage(HtmlHelper Html, dynamic Display, object Value) { var tagBuilder = new TagBuilder("span"); tagBuilder.InnerHtml = Html.Encode(Value is string ? (string)Value : Display(Value)); return MvcHtmlString.Create(tagBuilder.ToString()); } And here is what it would look like: Now what if we want to completely hide the pager if there is only one page? Well, the easiest way to do that is to override the Pager shape by dropping the following into the Views folder of your theme: @{ if (Model.TotalItemCount > Model.PageSize) { Model.Metadata.Alternates.Clear(); Model.Metadata.Type = "Pager_Links"; @Display(Model) } } And that’s it. The code in this template just adds a check for the number of items to display (in a template, Model is the shape) and only displays the Pager_Links shape if it knows that there’s going to be more than one page.

Migrating a WebLogic Domain from a 32 to a 64 bit JVM/Architecture

- by adejuanc

Currently on 32 bit OS which presents a physical constraint when trying to allocate memory. By limit, a 32 bit OS, will not be able to allocate more than 3 GB on a Linux environment, or 2 GB for Windows environment (not considering Physical Address Extension (PAE) implementation, which can increase the maximum allocatable memory). When this limit is reached, a migration to a 64 bit architecture is recommended. Below are the steps on how to install a 64 WebLogic Server version, along with a 64 Bit JVM and then how to migrate the domain to this new environment. Weblogic Server Version: WebLogic Server Version: 10.3.4.0 OS: Linux adejuan-cl.cl.oracle.com 2.6.18-194.el5 #1 SMP Mon Jan 01 22:10:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux JVM:java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Oracle JRockit(R) (build R28.1.1-13-139783-1.6.0_22-20101206-0136-linux-x86_64, compiled mode) To create migration template: 1. Execute $<WLS_HOME>/wlserver_10.3/common/bin/config_builder.sh 2. Create Domain Template. 3. Select Domain to migrate. 4. Enter the name of template and other info. Click next. 5. Using Add Button, Select libraries you want to add under lib folder. copy jdbc data sources you would like to have under config/jdbc folder. If you want to have log4j configuration, copy log4j.xml under domain_root folder. 6. Select data base for the domain and click next. 7. Enter Admin Server Name and port numbers. Click next. 8. Enter username and password. Click next. Select No if you don want to add users/groups/roles 9. Click next until reach button create. This will create a jar file that is needed for the next action plan. To install and migrate domain to 64 bit architecture. 1. Install JVM Jrockit R28.1.1.13 on environment. (uncompress zip folder on a known location) 2. Go to JRockit_Home/bin and execute $ java -d64 -jar wls1034_generic.jar 3. When prompt, select JRockit JVM in browse menu, and wait for installation to finish. 4. Go to <WLS_HOME>/wlserver_10.3/common/bin and execute $ ./config.sh 5. Select Create a new Weblogic domain 6. Select Base this domain on an existing template and select browse. 7. Select jar file created on previous action plan. 8. Select Name of domain. Maintain in most cases. 9. Select user name and password. Maintain in most cases. 10. Select Jrockit SDK 1.6.0_22 and click next. 11. Confirm all JMS/JDBC/security configuration. 12. On select Optional Configuration, reconfigure if necessary. 13. Check on Configuration summary for all domain configuration. 14. Click on create, to finish up domain import. Note: Always when installing a 64 bit WLS, it's necessary to install first the 64 JVM and then run the generic installer with the -d64 bit option. If this is not performed, the installation will be the 32 default version. For more information, please refer: http://download.oracle.com/docs/cd/E13188_01/jrockit/docs50/dev_faq.html#pae

Is it bad practice to make an iterator that is aware of its own end

- by aaronman

For some background of why I am asking this question here is an example. In python the method chain chains an arbitrary number of ranges together and makes them into one without making copies. Here is a link in case you don't understand it. I decided I would implement chain in c++ using variadic templates. As far as I can tell the only way to make an iterator for chain that will successfully go to the next container is for each iterator to to know about the end of the container (I thought of a sort of hack in where when != is called against the end it will know to go to the next container, but the first way seemed easier and safer and more versatile). My question is if there is anything inherently wrong with an iterator knowing about its own end, my code is in c++ but this can be language agnostic since many languages have iterators. #ifndef CHAIN_HPP #define CHAIN_HPP #include "iterator_range.hpp" namespace iter { template <typename ... Containers> struct chain_iter; template <typename Container> struct chain_iter<Container> { private: using Iterator = decltype(((Container*)nullptr)->begin()); Iterator begin; const Iterator end;//never really used but kept it for consistency public: chain_iter(Container & container, bool is_end=false) : begin(container.begin()),end(container.end()) { if(is_end) begin = container.end(); } chain_iter & operator++() { ++begin; return *this; } auto operator*()->decltype(*begin) { return *begin; } bool operator!=(const chain_iter & rhs) const{ return this->begin != rhs.begin; } }; template <typename Container, typename ... Containers> struct chain_iter<Container,Containers...> { private: using Iterator = decltype(((Container*)nullptr)->begin()); Iterator begin; const Iterator end; bool end_reached = false; chain_iter<Containers...> next_iter; public: chain_iter(Container & container, Containers& ... rest, bool is_end=false) : begin(container.begin()), end(container.end()), next_iter(rest...,is_end) { if(is_end) begin = container.end(); } chain_iter & operator++() { if (begin == end) { ++next_iter; } else { ++begin; } return *this; } auto operator*()->decltype(*begin) { if (begin == end) { return *next_iter; } else { return *begin; } } bool operator !=(const chain_iter & rhs) const { if (begin == end) { return this->next_iter != rhs.next_iter; } else return this->begin != rhs.begin; } }; template <typename ... Containers> iterator_range<chain_iter<Containers...>> chain(Containers& ... containers) { auto begin = chain_iter<Containers...>(containers...); auto end = chain_iter<Containers...>(containers...,true); return iterator_range<chain_iter<Containers...>>(begin,end); } } #endif //CHAIN_HPP

Notes - Part II - Play with JavaFX

- by Silviu Turuga

Open the project from last lesson Double click on NotesUI.fmxl, this will open the JavaFX Scene Builder On the left side you have a area called Hierarchy, from there press Del or Shift+Backspace on Mac to delete the Button and the Label. You'll receive a warning, that some components have been assigned an fx:id, click Delete as we don't need them anymore. Resize the AnchorPane to have enough room for our design, eg. 820x550px From the top left pick the Container called Accordion and drag over the AnchorPane design Chose then from Controls a List View and drag inside the Accordion. You'll notice that by default the Accordion has 2 TitledPane, and you can switch between them by clicking on their name. I'll let you the pleasure to do the rest in order to get the following result Here is the list of objects used Save it and then return to NetBeans Run the application and it should be run without any issue. If you click on buttons they all are functional, but nothing happens as we didn't link them with any action. We'll see this in the next episode. Now, let's play a little bit with the application and try to resize it… Have you notice the behavior? If the form is too small, some objects aren't visible, if it is too large there is too much space . That's for sure something that your users won't like and you as a programmer have to care about this. From NetBeans double click NotesUI.fmxl so to return back to JavaFX Scene Builder Select the TextField from bottom left of Notes, the one where I put the text Category and then from the right part of JavaFX Scene Builder you'll notice a panel called Inspector. Chose Layout and then click on the dotted lines from left and bottom of the square, like you see in the below image This will make the textfield to have always the same distance from left and bottom no matter the size of the form. Save and run the application. Note that whenever the form is changing the Height, the Category TextField has the same distance from the bottom. Select Accordion and do the same steps but also check the top dotted line, because we want the Accordion to have the same height as the main form has. I'll let you the pleasure to do the same for the rest of components. It's very important to design an application that can be resize by user and in the same time, all the buttons are on place. Last step is to make sure our application is not getting smaller then a certain size, as this will hide parts of our layout. So select the AnchorPane and from Inspector go to Layout and note down the Width and Height. Go back to NetBeans and open the file Main.java and add the following code just after stage.setScene(scene); (around line 26) stage.setMinWidth(820); stage.setMinHeight(550); Use your own width and height. This will prevent user to reduce the width or height of your application to a value that will hide parts of your layout. So now you should have done most of the design part and next time we'll see how can we enter some data into our newly created application… Note: in case you miss something, here are the source files of the project till this point.

How to disable irritating Office File Validation security alert?

- by Rabarberski

I have Microsoft Office 2007 running on Windows 7. Yesterday I updated Office to the latest service pack, i.e. SP3. This morning, when opening an MS Word document (.doc format, and a document I created myself some months ago) I was greeted with a new dialog box saying: Security Alert - Office File Validation WARNING: Office File Validation detected a problem while trying to open this file. Opening this is probably dangerous, and may allow a malicious user to take over your computer. Contact the sender and ask them to re-save and re-send the file. For more security, verify in person or via the phone that they sent the file. Including two links to some microsoft blabla webpage. Obviously the document is safe as I created it myself some months ago. How to disable this irritating dialog box? (On a sidenote, a rethorical question: Will Microsoft never learn? I consider myself a power user in Word, but I have no clue what could be wrong with my document so that it is considered dangerous. Let alone more basic users of Word. Sigh....)
