问题 Let's say we define an object like this: let object: AnyObject = { var result = UILabel(frame: CGRect(x: 0, y: 0, width: 150, height: 50)) result.text = "First Text" result.backgroundColor = UIColor.blueColor() return result }() For this example, I explicitly created a UILabel , but in my actual project I don't know what type of object is created, so I'm just treating the result as AnyObject for this example. The object is just a standard UILabel with text of "First Text" on a blue background

问题 This is a followup question to this question If I declare this as a singleton class: // Server.php class Server { private $stopper; private static $instance; public static getInstance() { if(!isset(self::$Server)) self::$Server = new static(); return self::$Server; } public function setStopper() { $this->stopper = TRUE; } public function startServer() { $self = $this; $consumer = new Consumer(); $consumer->onConsume(function($data) use($self, $consumer) { // some processing if($self-

问题 Or, to re-phrase it: can enum types be "mutable"? public enum Foo { ONE,TWO; private String bar; Foo() { this.bar = ""; } String bar() { return bar; } // legal? void bar(String bar) { this.bar = bar; } } I guess if I want to modify it, it's no longer an enum type. Thoughts? 回答1: It's absolutely valid. It's just a really bad idea. Callers are likely to expect the enum to be properly immutable. In some cases you might want to make it "appear" to be immutable, e.g. with caching, while still

问题 Can you create a dynamic javascript function and immediately call it? I already found that you can't use the callback from append. proposed, non working, code: <script type="text/javascript"> var count=1; $(document).ready(function(){ $(".main").append(' <script type="text/javascript">function init'+count+'(){alert("'+count+'");}<'+'/script> '); window['init'+count](); }); </script> <div class="main"></div> Edit: Narrowed it down to a synchronization problem. Placing alert("") between append

问题 Okay so I have a YUI Datatable. Most of it is exactly as the how to guide says to construct it. I have an event that governs changing the rows per page. It's linked to the rows per page drop down element and it saves the value of that drop down as a cookie when the drop down is changed. var onRPPChange1 = YAHOO.util.Event.addListener("yui-pg0-1-rpp24", "change", getRPP_1); The problem is that "yui-pg0-1-rpp24" (the ID of the drop down) changes whenever I make updates to my data table. I would

问题 Following up my previous question: ElasticSearch overriding mapping from text to object I have an index template: { "template" : "project.*", "order" : 100, "dynamic_templates": [ { "message_field": { "mapping": { "type": "object" }, "match": "message" }, "message_properties": { "path_match": "message.*", "mapping": { "type": "string", "index": "not_analyzed" } } } ] } which basically creates new fields for everything under "message" field. I am doing this because "message" field is mapped as

问题 I Have created a procedure which has code like this: Create PROCEDURE Sample( @ID INT ) AS BEGIN DECLARE @SQL NVARCHAR(max) DECLARE @SchemaName SYSNAME DECLARE @TableName SYSNAME DECLARE @DatabaseName SYSNAME SELECT @SQL = 'Create Table ' + @DatabaseName + '.' + @SchemaName + '.' + @TableName + '_temp' + '(' SELECT @SQL = @SQL + 'ID int NOT NULL Primary Key, Name VarChar(10))' I Always get error as : Msg 102, Level 15, State 1, Line 77 Incorrect syntax near ','. Can anyone help me on this?

问题 This question is old now, Dapper data-view binding are fixed as shown answer below :) 回答1: I've added TypeDescriptor -based bindings to DapperRow , which means that anything obtained via Query() (the dynamic API) should now bind to much common UI controls. Anything from 1.60.5 or above should work. Let me know! Caveat: it doesn't currently work for empty results (zero rows). I know how to implement that (see notes here), but that would require some additional changes to the query

问题 I am adding various dynamically created controls to a panel, based on what the user selects. If a Groupbox, with associated RadioButtons, is the first control, it looks fine: ...but if it's anything other than that, the associated radio buttons seem right-aligned instead of left-aligned, as seen above, and the groupbox is too wide, to boot. Here is the pertinent code (RepaintMockupPanel() is called when the user opts to see what his mockup looks like at any time, and getGroupBox() is the
