  • Insert unicode strings into CleverCSS

    - by Brian M. Hunt
    How can one insert a Unicode string CSS into CleverCSS? In particular, how could one produce the following CSS using CleverCSS: li:after { content: "\00BB \0020"; } I've figured out CleverCSS's parsing rules, but suffice that the permutations I've thought sensible have failed, for example: li: content: "\\00BB \\0020" // becomes content: 'BB 0' EDIT: My other examples and the rest of my post weren't saved. Suffice that I had a longer list of examples that also failed, as did my closing which was something like: I'd be grateful for any thoughts and input. Brian

  • load google annotated chart within jquery ui tab content via ajax method

    - by twmulloy
    Hi, I am encountering an issue with trying to load a google annotated chart (http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html) within a jquery ui tab using content via ajax method (http://jqueryui.com/demos/tabs/#ajax). If instead I use the default tabs functionality, writing out the code things work fine: <div id="tabs"> <ul> <li><a href="#tabs-1">Chart</a></li> </ul> <div id="tabs-1"> <script type="text/javascript"> google.load('visualization', '1', {'packages':['annotatedtimeline']}); google.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'cloudofinc.com'); data.addColumn('string', 'header'); data.addColumn('string', 'text') data.addColumn('number', 'All Clients'); data.addRows([ [new Date('May 12, 2010'), 2, '2 New Users', '', 3], [new Date('May 13, 2010'), 0, undefined, undefined, 0], [new Date('May 14, 2010'), 0, undefined, undefined, 0], ]); var chart = new google.visualization.AnnotatedTimeLine(document.getElementById('chart_users')); chart.draw(data, { displayAnnotations: false, fill: 10, thickness: 1 }); } </script> <div id='chart_users' style='width: 100%; height: 400px;'></div> </div> </div> But if I use the ajax method for jquery ui tab and point to the partial for the tab, it doesn't work completely. The page renders and once the chart loads, the browser window goes white. However, you can see the tab partial flash just before the chart appears to finish rendering (the chart never actually displays). I have verified that the partial is indeed loading properly without the chart. <div id="tabs"> <ul> <li><a href="ajax/tabs-1">Chart</a></li> </ul> </div>

  • Approaches to create a nested tree structure of NSDictionaries?

    - by d11wtq
    I'm parsing some input which produces a tree structure containing NSDictionary instances on the branches and NSString instance at the nodes. After parsing, the whole structure should be immutable. I feel like I'm jumping through hoops to create the structure and then make sure it's immutable when it's returned from my method. We can probably all relate to the input I'm parsing, since it's a query string from a URL. In a string like this: a=foo&b=bar&a=zip We expect a structure like this: NSDictionary { "a" => NSDictionary { 0 => "foo", 1 => "zip" }, "b" => "bar" } I'm keeping it just two-dimensional in this example for brevity, though in the real-world we sometimes see var[key1][key2]=value&var[key1][key3]=value2 type structures. The code hasn't evolved that far just yet. Currently I do this: - (NSDictionary *)parseQuery:(NSString *)queryString { NSMutableDictionary *params = [NSMutableDictionary dictionary]; NSArray *pairs = [queryString componentsSeparatedByString:@"&"]; for (NSString *pair in pairs) { NSRange eqRange = [pair rangeOfString:@"="]; NSString *key; id value; // If the parameter is a key without a specified value if (eqRange.location == NSNotFound) { key = [pair stringByReplacingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; value = @""; } else { // Else determine both key and value key = [[pair substringToIndex:eqRange.location] stringByReplacingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; if ([pair length] > eqRange.location + 1) { value = [[pair substringFromIndex:eqRange.location + 1] stringByReplacingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; } else { value = @""; } } // Parameter already exists, it must be a dictionary if (nil != [params objectForKey:key]) { id existingValue = [params objectForKey:key]; if (![existingValue isKindOfClass:[NSDictionary class]]) { value = [NSDictionary dictionaryWithObjectsAndKeys:existingValue, [NSNumber numberWithInt:0], value, [NSNumber numberWithInt:1], nil]; } else { // FIXME: There must be a more elegant way to build a nested dictionary where the end result is immutable? NSMutableDictionary *newValue = [NSMutableDictionary dictionaryWithDictionary:existingValue]; [newValue setObject:value forKey:[NSNumber numberWithInt:[newValue count]]]; value = [NSDictionary dictionaryWithDictionary:newValue]; } } [params setObject:value forKey:key]; } return [NSDictionary dictionaryWithDictionary:params]; } If you look at the bit where I've added FIXME it feels awfully clumsy, pulling out the existing dictionary, creating an immutable version of it, adding the new value, then creating an immutable dictionary from that to set back in place. Expensive and unnecessary? I'm not sure if there are any Cocoa-specific design patterns I can follow here?

  • Releasing an OLE IStorage file handle in C#

    - by Bernard Darnton
    I'm trying to embed a PDF file into a Word document using the OLE technique described here: http://blogs.msdn.com/brian_jones/archive/2009/07/21/embedding-any-file-type-like-pdf-in-an-open-xml-file.aspx I've tried to implement to C++ code provided in C# so that the whole project's in one place and am almost there except for one roadblock. When I try to feed the generated OLE object binary data into the Word document I get an IOException. IOException: The process cannot access the file 'C:\Wherever\Whatever.pdf.bin' because it is being used by another process. There is a file handle open the .bin file and I don't know how to get rid of it. I don't know a huge amount about COM - I'm winging it here - and I don't know where the file handle is or how to release it. Here's what my C#-ised code looks like.

  • Does the asp.net RoleManager really cache the roles for a user in a cookie if so configured?

    - by Ralph Shillington
    In my web.config I have the Role Manager configured as follows: <roleManager enabled="true" cacheRolesInCookie="true" cookieName=".ASPROLES" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="All"> however in our custom RoleProvider it would seems that the GetRolesForUser method is always being called, rather than as I would have expected, the RoleManager serving up the roles from its cookie. We're using something like to get the roles for a user: string[] myroles = Role.GetRolesForUser("myuser"); Is there something that I'm missing in the configuration, or in the use of the RoleManager Thanks in advance

  • Getting started with XSD validation with C#

    - by Rosarch
    Here is my first attempt at validating XML with XSD. The XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <config xmlns="Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd"> <levelVariant> <filePath>SampleVariant</filePath> </levelVariant> <levelVariant> <filePath>LegendaryMode</filePath> </levelVariant> <levelVariant> <filePath>AmazingMode</filePath> </levelVariant> </config> The XSD, located in "Schemas/config.xsd" relative to the XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xs:element name="config"> <xs:complexType> <xs:sequence> <xs:element name="levelVariant"> <xs:complexType> <xs:sequence> <xs:element name="filePath" type="xs:anyURI"> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> Right now, I just want to validate the XML file precisely as it appears currently. Once I understand this better, I'll expand more. Do I really need so many lines for something as simple as the XML file as it currently exists? The validation code in C#: public void SetURI(string uri) { XElement toValidate = XElement.Load(Path.Combine(PATH_TO_DATA_DIR, uri) + ".xml"); // begin confusion string schemaURI = toValidate.Attributes("xmlns").First().ToString() + toValidate.Attributes("xsi:noNamespaceSchemaLocation").First().ToString(); XmlSchemaSet schemas = new XmlSchemaSet(); schemas.Add("", XmlReader.Create( SOMETHING )); XDocument toValidateDoc = new XDocument(toValidate); toValidateDoc.Validate(schemas, null); // end confusion root = toValidate; } Any illumination would be appreciated.

  • JSON Post To Rails From Android

    - by Stealthnh
    I'm currently working on an android app that interfaces with a Ruby on Rails app through XML and JSON. I can currently pull all my posts from my website through XML but I can't seem to post via JSON. My app currently builds a JSON object from a form that looks a little something like this: { "post": { "other_param": "1", "post_content": "Blah blah blah" } } On my server I believe the Create method in my Posts Controller is set up correctly: def create @post = current_user.posts.build(params[:post]) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render json: @post, status: :created, location: @post } format.xml { render xml: @post, status: :created, location: @post } else format.html { render action: "new" } format.json { render json: @post.errors, status: :unprocessable_entity } format.xml { render xml: @post.errors, status: :unprocessable_entity } end end end And in my android app I have a method that takes that JSON Object I posted earlier as a parameter along with the username and password for being authenticated (Authentication is working I've tested it, and yes Simple HTTP authentication is probably not the best choice but its a quick and dirty fix) and it then sends the JSON Object through HTTP POST to the rails server. This is that method: public static void sendPost(JSONObject post, String email, String password) { DefaultHttpClient client = new DefaultHttpClient(); client.getCredentialsProvider().setCredentials(new AuthScope(null,-1), new UsernamePasswordCredentials(email,password)); HttpPost httpPost = new HttpPost("http://mysite.com/posts"); JSONObject holder = new JSONObject(); try { holder.put("post", post); StringEntity se = new StringEntity(holder.toString()); Log.d("SendPostHTTP", holder.toString()); httpPost.setEntity(se); httpPost.setHeader("Content-Type","application/json"); } catch (UnsupportedEncodingException e) { Log.e("Error",""+e); e.printStackTrace(); } catch (JSONException js) { js.printStackTrace(); } HttpResponse response = null; try { response = client.execute(httpPost); } catch (ClientProtocolException e) { e.printStackTrace(); Log.e("ClientProtocol",""+e); } catch (IOException e) { e.printStackTrace(); Log.e("IO",""+e); } HttpEntity entity = response.getEntity(); if (entity != null) { try { entity.consumeContent(); } catch (IOException e) { Log.e("IO E",""+e); e.printStackTrace(); } } } Currently when I call this method and pass it the correct JSON Object it doesn't do anything and I have no clue why or how to figure out what is going wrong. Is my JSON still formatted wrong, does there really need to be that holder around the other data? Or do I need to use something other than HTTP POST? Or is this just something on the Rails end? A route or controller that isn't right? I'd be really grateful if someone could point me in the right direction, because I don't know where to go from here.

Person has two properties, NSString *firstName and NSString *lastName. What's the best way to search through the array to find everyone who matches 'Ken' anywhere in the firstName OR lastName properties?

  • "Wrapping" a BindingList<T> propertry with a List<T> property for serialization.

    - by Eric
    I'm writing an app that allows users search and browse catalogs of widgets. My WidgetCatalog class is serialized and deserialized to and from XML files using DataContractSerializer. My app is working now but I think I can make the code a lot more efficient if I started taking advantage of data binding rather then doing everything manually. Here's a stripped down version of my current WidgetCatalog class. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataContract(Name = "Name")] public string Name { get; set; } [DataContract(Name = "Widgets")] public List<Widget> Widgets { get; set; } } I had to write a lot of extra code to keep my UI in sync when widgets are added or removed from a catalog, or their internal properties change. I'm pretty inexperienced with data-binding, but I think I want a BindingList<Widget> rather than a plain old List<Widget>. Is this right? In the past when I had similar needs I found that BindingList<T> does not serialize very well. Or at least the Event Handers between the items and the list are not serialized. I was using XmlSerializer though, and DataContractSerializer may work better. So I'm thinking of doing something like the code below. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataMember(Name = "Name")] public string Name { get; set; } [DataMember(Name = "Widgets")] private List<Widget> WidgetSerializationList { get { return this._widgetBindingList.ToList<Widget>(); } set { this._widgetBindingList = new BindingList<Widget>(value); } } //these do not get serialized private BindingList<Widget> _widgetBindingList; public BindingList<Widget> WidgetBindingList { get { return this._widgetBindingList; } } public WidgetCatalog() { this.WidgetSerializationList = new List<Widget>(); } } So I'm serializing a private List<Widget> property, but the GET and SET accessors of the property are reading from, and writing to theBindingList<Widget> property. Will this even work? It seems like there should be a better way to do this.
