[ "Animations in AngularJS 1.2 - How To", "I tried to use animations within my app but unfortunately to no avail. I checked lots of examples, blog, downloaded animate.css etc etc. \n\nI injected animation module, tried basic examples, tried following tutorials for instance, but it seems I miss something every time.\n\nCan someone please provide exact instructions for AngularJS v1.2 animations to work, with injections, inclusions and everything you need to do to get them working? Maybe a step-by-step instructions on how you usually do your animations.\n\nA basic fadein/fadeout example on ng-show/hide would suffice.\n\nThank you very much" ]

[ "VBA Command Button array", "I'm currently working on a project where I'll be selecting up to 5 items to compare to each other, with the results being displayed in up to a 5x5 dynamic grid.

However, everything I've read suggests that I need to create a class to handle the button clicks, since I don't feel like making 20 subroutines that all have the same code in them.

To me, it makes more sense to take the list of packages to be required, convert them to a string separated by spaces, and then pass that as an argument.\n\nIn my research I found that I could convert a list to a string with the join filter, so I tried this:\n\n- name: \"Require packages\"\n composer:\n command: require\n arguments: {{ modules | join(\" \" ) }}\n working_dir: \"{{ app['directory'] }}\"\n\n\nBut, this gives me a YAML syntax error:\n\nThe offending line appears to be:\ncommand: require\narguments: {{ modules | join(\" \") }}\n ^ here\n\n\nI've tried wrapping \"{{ modules | join(\" \") }}\" but I get yelled at for the quotes in the parenthesis. \n\nAm I approaching this idea in the right way, or what questions do I need to ask to get to the answer?

[ "How to add UserControl to a Panel on a WPF Window", "I think I'm missing something that should be obvious here, but I'm drawing a blank on this one.\n\nI've built a very primitive UserControl containing nothing more than a TextBox to use as a log window:\n\n<UserControl x:Class=\"My.LoggerControl\"\n xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"\n xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"\n xmlns:mc=\"http://schemas.openxmlformats.org/markup-compatibility/2006\" \n xmlns:d=\"http://schemas.microsoft.com/expression/blend/2008\"\n x:Name=\"LoggerView\">\n <Grid x:Name=\"LayoutRoot\">\n <TextBox x:Name=\"LogWindow\" AcceptsReturn=\"True\"/>\n </Grid>\n</UserControl>\n\n\nI don't expect that to be the best way to do it, but it should be good enough for a prototype.\n\nThe code-behind is similarly simple:\n\npublic partial class LoggerControl : UserControl, ILogger\n{\n public LoggerControl()\n {\n InitializeComponent();\n }\n\n private LogLevel level = LogLevel.Warning;\n\n #region ILogger\n\n public LogLevel Level\n {\n get { return level; }\n set { level = value; }\n }\n\n public void OnError(string s)\n {\n if (level >= LogLevel.Error)\n LogWindow.AppendText(\"ERROR:::\" + s + \"\\n\");\n }\n\n // ...\n #endregion\n}\n\n\nThe thing I can't figure out is how to add this control to my MainWindow.xaml. Simplifying, lets say my window looks like this:\n\n<Window x:Class=\"My.MainWindow\"\n xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"\n xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"\n xmlns:local=\"clr-namespace:My\"\n Title=\"Test\" Height=\"350\" Width=\"525\">\n <Grid>\n <local:LoggerControl x:Name=\"LogView\" />\n </Grid>\n</Window>\n\n\nEven with something so simple, the Designer in Visual Studio 2010 can't load the main window. The error given is:\n\n\n A value of type 'LoggerControl' cannot be added to a collectionor dictionary of type 'UIElementCollection'.\n\n\nThis error message has only one unrelated hit in the major search engines (plus duplicates) so I haven't found any useful help. Microsoft's own documentation seems to imply that this should work.\n\nAny idea how to solve this?" ]
