• Why isn't Expression Blend rendering my User Control? It's only showing XAML.

  - by unforgiven3

  I'm opening valid XAML within my VS2008 solution in Expression Blend 3 and it is only showing XAML when I try to open individual XAML files. My solution/projects all build and run correctly. When I go to View - Active Document View the Design View, Split View and XAML View options are all grayed out... which doesn't make much sense. I'm not much of a Blend user, but this has never happened before, and I'm coming up blank for how to fix it. Any ideas?

• Weird behavior of substitution in Mathematica.

  - by Ilya

  My question is: why doesn't the following work, and how do I fix it? Plot[f[t], {t, 0, 2*Pi}] /. {{f -> Sin}, {f -> Cos}} The result is two blank graphs. By comparison, DummyFunction[f[t], {t, 0, 2*Pi}] /. {{f -> Sin}, {f -> Cos}} gives {DummyFunction[Sin[t], {t, 0, 2 *Pi}], DummyFunction[Cos[t], {t, 0, 2 * Pi}]} as desired. This is a simplified version of what I was actually doing. I was very annoyed that, even after figuring out the annoying "right way" of putting the curly brackets nothing works. In the end, I did the following, which works: p[f_] := Plot[f[t], {t, 0, 2*Pi}] p[Sin] p[Cos]

• Rails single table inheritance/subclass find condition in parent

  - by slythic

  Hi all, I have a table called Users (class User < ActiveRecord::Base) and a subclass/STI of it for Clients (class Client < User). Client "filtering" works as expected, in other words Client.find(:all) works to find all the clients. However, for users I need to filter the result to only find users that are NOT clients (where type is null or blank). I've tried the following in my index controller but no matter what I put for the type it returns all users regardless of type. User.find(:all, :conditions => { :type => nil }, :order => 'name') Any clue on how to get this condition to work? Thanks!

• Accessing Content from MDF after attached to SQL

  - by Fidelis

  Hello, I am using WSS 3.0 and trying to restore a mdf. I attached the database in SQL Management Studio, created a new web application, and associated the database to it. When I go into Central Administration- Application Management - Content Databases I see the WSS_Content and it says Sites: 2. One of the sites looks more similar to the other. I was able to log into the Sharepoint web app that has the db attached to it, and while it gives me the basic structure of the backed up site, the content of lists is blank, that was the data I was really after (Announcements, tasks, etc exist as lists but are empty). How do I get access to this?

• C# Question:Dynamically Disable ToolStripMenuItems/ToolStripButtons in an MDIParent Form: Which Even

  - by RedEye

  Any guidance on the following issue would be greatly appreciated. In which MDIParent event should I disable the items/buttons? Activated? On program Launch, I want the buttons disabled. If there are no active MDIChildren, I want the buttons disabled. When I launch a child form, I want to test that child form for data. If it is a blank form, I want the buttons to remain disabled. I currently have my code in the MdiChildActivated Event Handler. Thanks for your time.

• How to show a progress report to the user in Google Apps Script?

  - by Jose M Vidal

  I have a simple script that will send out a bunch of emails but these take time to send and I want to show the user a scrolling window with the emails addresses as they are sent (or, a progress bar would be good too). I believe this is possible with the new User Interface Classes, but I can't get it to work. The documentation is kinda sparse. Specifically, the problem is that the GUI window that pops up appears blank until all the emails have been sent (the script ends) and then the text appears. This happens even if I call show(myapp) after every time I update the Label.

• $.Post with Form submit

  - by Michael

  ...Some form gets submitted... $.("form").submit(function() { saveFormValues($(this), "./../.."; } function saveFormValues(form, path) { var inputs = getFormData(form); var params = createAction("saveFormData", inputs); var url = path + "/scripts/sessions.php"; $.post(url, params); } The weird thing is that if i add a function to the $.post(url, params, function(data) { alert(data); } I get a blank alert statement. Within scripts/sessions.php i have a function to save whatever the $_POST information is to a file, and the sessions.php never saves this saveFormValues call. It never shows up to the file. But if i keep trying to get it to save, about once every 15 will actually allow it to be saved. This leads me to believe that the forms POST is somehow blocking this value saving post. Any help?

• Unicode issue in Django

  - by Kave

  I seem to have a unicode problem with the deal_instance_name in the Deal model. It says: coercing to Unicode: need string or buffer, __proxy__ found The exception happens on this line: return smart_unicode(self.deal_type.deal_name) + _(u' - Set No.') + str(self.set) The line works if I remove smart_unicode(self.deal_type.deal_name) but why? Back then in Django 1.1 someone had the same problem on Stackoverflow I have tried both the unicode() as well as the new smart_unicode() without any joy. What could I be missing please? class Deal(models.Model): def __init__(self, *args, **kwargs): super(Deal, self).__init__(*args, **kwargs) self.deal_instance_name = self.__unicode__() deal_type = models.ForeignKey(DealType) deal_instance_name = models.CharField(_(u'Deal Name'), max_length=100) set = models.IntegerField(_(u'Set Number')) def __unicode__(self): return smart_unicode(self.deal_type.deal_name) + _(u' - Set No.') + str(self.set) class Meta: verbose_name = _(u'Deal') verbose_name_plural = _(u'Deals') Dealtype: class DealType(models.Model): deal_name = models.CharField(_(u'Deal Name'), max_length=40) deal_description = models.TextField(_(u'Deal Description'), blank=True) def __unicode__(self): return smart_unicode(self.deal_name) class Meta: verbose_name = _(u'Deal Type') verbose_name_plural = _(u'Deal Types')

• How to create an Audio CD using C# or Java

  - by Elie

  I'm looking for an API that would allow me to create an audio CD from within a C# application. The CDs are to be created and closed in the same session (no rewrite required). Basically, my application locates files on behalf of a user, and, if a blank CD is present in the drive, creates an audio CD for the user. If no CD is present, it checks to see if there's a USB drive attached and copies the files there (this part I already know how to do). I would prefer to write this application in either C# or Java, as I'm most comfortable with those, but I don't know how hard it would be to create CDs using either language. There are several other questions here that deal with regular CDs, but I didn't see any discussing audio CDs.

• Problem using Blend 3 Interaction.Behaviours in VS2010

  - by Andre Luus

  There seems to be a problem with support for the Interactivity namespace of Blend 3 in the VS2010 xaml editor. I have the following installed: VS2010 Blend 3 + Blend 3 SDK I am trying to compile a demo project that is targeted at .Net 4 Client Profile and has a reference to System.Windows.Interactivity (in the Blend 3 folder). In the object browser everything appears to be fine. I can also access Interaction.Behaviours from code-behind, but if I put the namespace xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" in the xaml file and try to use it, the intellisense is blank. If I copy something in there anyway, the compiler says: The tag 'Interaction.Behaviors' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactivity'. Do I need to install Blend 4 RC or something?

• ASP C# Web Developer default login, getting user ID session value

  - by m3n

  I've used the built-in wizard in Visual Web Developer 2008 to create a simple login system. I'd like to get hold of the logged in user's ID, but I'm not sure how. Peeking in the ASPNETDB.MDF in the table aspnet_Users, the column appears to be called "UserId". I gave it a go: Response.Write("ID: " + Session["UserId"]); but it's coming up blank. How do I do this? (This is not for a live project, no need to point out the sillyness in using the wizard.) Thanks

• Rails 3 Beta 2, Haml, Nested Layouts and LocalJumpError

  - by CJ Bryan

  Alright, I'm trying to create an app with nested templates. I'm using Rails 3 Beta 2 and Haml. I've poked around and I've decided to take the clearest approach and have structured my templates like so: # application.html.haml !!! %body %h1 Outermost Template = yield(:foobar) # inner.html.haml - content_for :foobar do %h2 Inner Template = yield = render :file => 'layouts/application' # foo_controller.rb layout 'inner' With all of this, I get a LocalJumpError with the message no block given. The stack traces are blank and pretty unhelpful. Any ideas? Are these known issues?

• How do I use unmanaged DLL in C++ win32 application?

  - by Nick

  I have a 3rd party DLL that I am trying to use in a win32 C++ application. The DLL alone is all that I have. I believe this library is written in C and I assume is not exposed to COM. Is LoadLibrary() the function must commonly used for this task in Windows? If so can someone provide me with an example of how it is used? I created a blank win32 in VS so I don't have any of the windows specific headers included etc. Thanks!

• Send bulk email from SQL Server 2008

  - by dbnewbie

  Hi, I am relatively new to databases,so please forgive me if my query sounds trivial. I need to send bulk email to all the contacts listed in a particular table. The body of the email is stored in a .doc file which begins as Dear Mr. _. The SQL server will read this file, append the last name of the contact in the blank space and send it to the corresponding email address for that last name. Any thoughts on how to proceed with this? Any insights,suggestions,tips will be greatly appreciated. Thanks!

• missing duration in iis 7.5 Failed Request Tracing on server core

  - by Phil McCracken

  We have Failed Request Tracing working on IIS7.5 (Windows 2008 Server Core) and our rule has ASP.NET checked off and verbose logging set. However, on many googled screenshots of what a typical failed request trace looks like, we see the actual duration of each subpart in milliseconds shown to the right of the word verbose on the "request details" tab. Viewing our XML in IE shows no such thing to the right of the word verbose. Furthermore, The "Performance View" tab is blank; so no help viewing the durations there either. Is there something we need to enable? What gives?

• Building java project with TFS

  - by Jaco Pretorius

  A very small portion of our codebase is some legacy Java code. I'm trying to add a new build that would invoke ant to build this project. The first problem is that TFS doesn't allow you to create a build that doesn't build a .Net solution. I got around this by copying a previous build file and adding an EndToEndIteration task which is the entry point for the build. The problem is that none of the usual build variables are populated - $(BuildDirectory), $(SolutionRoot) - all blank. This pretty much means I can't invoke my ant task without hardcoding the paths (which I definitely can't do). Any ideas?

• How to escape HAML for Javascript in Sinatra

  - by viatropos

  I would like to return a list/combobox from an ajax request ("Which on of these do you like?" type thing). I would like to write that little snippet in HAML, which converts it to HTML, but when I do, the page goes blank. I'm assuming this is because the HTML isn't escaped. Is there a way to escape HAML so I can do $("#mydiv").html(response);? Here's the method: post "/something" do # process... haml :"partials/_select", :layout => false, :locals => {:collection => choices} end ... the haml template: %select - collection.each do |item| %option{:value => item.to_s}= item.to_s ... and the javascript: success: function(responseText, statusText, xhr, $form) { $(".dialog_content").append(responseText); } I have tried the sinatra_more plugin and the escape_javascript method, but there's problems with the haml buffer in sinatra. Any ideas?

• Removing the image from an IKImageView

  - by Brian Postow

  I have an IKImageView that is coming up effectively un-initialized. This is happening effectively in an error-state (The user is unregistered) so I haven't had a chance to put an image in it yet. In 10.6, this comes up fine, with a black rectangle. In 10.5, however, it comes up with garbage. some rectangles of noise, some rectangles of copies of the desktop, etc. I've tried setting the ZoomFactor to 0.0, I've tried setting the image to nil, but it appears that the problem is beyond that. any ideas? (My next kludge is going to be to ship tiny blank image with the app, and try to get it to load that... but that's kind of silly)
