问题 I've created an event receiver and have added to the GAC. How do I bound an event receiver to a specific custom content type? I need to do this from an XML file: So far I have: Feature.xml that points to an Elements.xml file but am not sure about the Elements.xml file. How do you reference a specific content type? (I have the guid for the specific content-type) 回答1: To bind an event receiver to a specific content type, you use the XmlDocuments element of the content type elements file. Here's

问题 How can i prevent users to enter new characters after max character limit is reached ? Ckeditor charcount plugin just shows me the remaining characters, i want it to stop at 0.

The correct way to do a tunneled event

由 浪尽此生 提交于 2019-12-05 01:49:13
问题 EDIT : I guess I asked a bit of a XY Problem. I don't really care about getting tunneled events working, what I care about is getting a event raised from the code behind of the parent window to be picked up and reacted to by a control that is a child of that window without explicitly needing to tell the child who its parent is and manually subscribing to the event. I am trying to raise a event in a parent control and having the child controls listen for that event and react to it. From my

how to attach jquery event handlers for newly injected html?

由 守給你的承諾、 提交于 2019-12-05 01:42:30
How would I use .on() if the HTML is not generated yet? The jQuery page says If new HTML is being injected into the page, select the elements and attach event handlers after the new HTML is placed into the page. But I'm not really sure how to do that. Is there a way to "reload" the event handler? So if I had $(document).ready(function(){ $('.test').on('click', function(){ var id = $(this).attr('id'); console.log("clicked" + id); }); generatePage(); }); where generatePage() creates a bunch of divs with .test , how would I rebind .on() ? I'm aware similar questions have been asked, but I didn't

Can I determine if a KeyEventArg is an letter or number?

由 瘦欲@ 提交于 2019-12-05 01:35:33
Is there a way to determine if a key is letter/number ( A-Z , 0-9 ) in the KeyEventArgs ? Or do I have to make it myself? I found a way with e.KeyCode , is that accurate? if(((e.KeyCode >= Keys.A && e.KeyCode <= Keys.Z ) || (e.KeyCode >= Keys.D0 && e.KeyCode <= Keys.D9 ) || (e.KeyCode >= Keys.NumPad0 && e.KeyCode <= Keys.NumPad9)) You can use the char.IsLetterOrDigit() method on the KeyCode of the event args: bool isLetterOrDigit = char.IsLetterOrDigit((char) keyEventArgs.KeyCode); Char.IsNumber() and Char.IsLetter() In WPF? Use PreviewTextInput or TextInput events instead of KeyDown 来源： https

SWT: Getting notified of a system device change (USB device connection / disconnection)

由 别等时光非礼了梦想. 提交于 2019-12-05 01:31:29
问题 I'm writing an SWT application which needs to sit in the system tray and pop up automatically whenever the user connects some USB device (the application serves as its control panel). The way to do this in the native environment (win32 in this case, but I should be platform-independent ultimately) is to listen to the WM_DEVICECHANGE event, then checking if my device has been disconnected. Googling the subject, it seems like SWT does not in fact handle this type of event. Does anyone have any

Difference Between RoutedEventHandler and EventHandler

What is the difference between this.Loaded += new RoutedEventHandler(MainWindow_Loaded); and childWindow.MyEvent += new EventHandler(childWindow_MyEvent); rockyashkumar I assume you want to know what's the difference between Events and Routed Events. These 2 articles might help you: https://msdn.microsoft.com/en-us/library/ms742806(v=vs.100).aspx (a MSDN article) http://joshsmithonwpf.wordpress.com/2008/03/18/understanding-routed-commands/ (a great article about Routed Commands that also contains a very nice explanation of Routed Events) In short, RoutedEvents are routed. They can bubble up or

Best practices for passing data between processes in Cocoa

由 我只是一个虾纸丫 提交于 2019-12-05 01:23:25
问题 I am in the middle of solving a problem which requires me to do the following in my 64-bit Cocoa application: Spawn a 32-bit Cocoa helper tool (command line tool) from within my application. This helper will open a file (a quicktime movie to be precise) and access information about that file using 32-bit only APIs (Quicktime-C APIs) The data gathered from the 32-bit process needs to be passed back to the 64-bit application. The 64-bit app should wait until the 32-bit process completes before

Function listener in javascript and/or jQuery

由 六眼飞鱼酱① 提交于 2019-12-05 01:01:41
Wondering if there is an elegant way to listen for a function in javascript and/or jQuery. Rather than listening for a $('#mything').click(function(){ //blah }) I'd like to listen for when a specific function is fired off. I don't want to edit the function as it's within a library that I don't want to hack directly. I did find this: http://plugins.jquery.com/project/jqConnect which connects functions. But wondering about a better technique. The only way to do this is to override the function (ie, hack the library): (function() { var oldVersion = someLibrary.someFunction; someLibrary
