SharePoint Document or Item Download/View Event Handler?

阅读更多关于 SharePoint Document or Item Download/View Event Handler?

Is there any way to capture document download or item view actions in SharePoint 2010/2007? Thanks. I had a similar requirement in that I had to send an email when a document was downloaded. In WSS 3.0, I wrote an Http Module that looked at the request url and if the prefix of the request matched my document library URL, I captured that download/view. Go to Site Settings > Site Collection Administration > Site collection audit settings. Under Documents and Items, check Opening or downloading documents, viewing items in lists, or viewing item properties. 来源： https://stackoverflow.com/questions

How can I make the up and down arrow keys navigate a table's rows, and programmatically apply the sudo :hover to those rows?

阅读更多关于 How can I make the up and down arrow keys navigate a table's rows, and programmatically apply the sudo :hover to those rows?

I have an input of type text that is used to perform asynchronous table row searches using jquery. I have an .on function attached to the search input and on key down, I'm calling a function called hoverDown(). What I would like to happen when the down arrow key is pressed, is to hover over the table rows. And when a table row is hovered over with the arrow key, and the user hits enter, I would like for the href to fire and take the user to that related page. I am able to detect the e.keyCode but that's about as far as I've been able to get and I really don't know where to take it from here.

Use of ckeditor “key” CKEDITOR.instances.editor.on('key', function (e){

阅读更多关于 Use of ckeditor “key” CKEDITOR.instances.editor.on('key', function (e){

I realize there are questions about how to implement an event handler for CKEDITOR 4. I am able to use this code to get the key-down data, but I can't seem to get the data after a key-up: CKEDITOR.instances.editor.on('key', function (e){ document.getElementById("preview").innerHTML = CKEDITOR.instances.editor.getData(); }); So when I type a string like "aaa" into the text editor field, the first character is never fetched. So my div id="preview" will only show "aa". I've iterated over the e object, which is quite complex, but nothing there strikes me as useful to solving this. I also don't see

Let parent View assume MotionEvents if child returns false

I have a application that need event handling on a unusual way. For my question, let me first explain a simple case that the current event handling system of Android don't fits for me. Supposing that I have a FrameLayout (that I'll call ViewSwiper since now) that all Views added on it are MATCH_PARENT X MATCH_PARENT (that I'll call PageView), it's handles events by translating the actual View and replace it based on the direction of moving. This component I already have done and work properly ( Using Animation to swipe views ). But the problem is on that PageView I add on top of it, in case of

event.pageX not working in Firefox, but does in Chrome

阅读更多关于 event.pageX not working in Firefox, but does in Chrome

I am having what I thought was a simple problem, but after about a week of searching for the solution I can't seem to find the reason behind it. Basically I am calling the function below every time the mouse is clicked, and it works fine in Chrome, but in Firefox the alert("This is not called") never gets called. I know the problem is in the two lines of code: x = event.pageX - canvas.offsetLeft; y = event.pageY - canvas.offsetTop; but can't seem to find whats wrong. Mozillas site says that event.pageX is a legitimate command to call, and as well the canvas.offsetLeft . But the function still

Should I use EventHandler<T> and/or the EventArgs delegate pattern?

阅读更多关于 Should I use EventHandler and/or the EventArgs delegate pattern?

问题 Reading my C# book, it talks about using events/delegates (I am assuming I am right in thinking an event is the equivalent of a public delegate which has no member variable access) in a pattern liked by MS: public delegate Something(object o, EventArgs e) And then goes onto explain about EventArgs<T> which basically removes the need for the delegate declaration: public EventHandler<SomeEventArgs> events Which is the same as (I think) private delegate Something(object o, SomeEventArgs e);

I have an OnIdle handler in my D2006 app. With this code: procedure TMainForm.ApplicationEvents1Idle(Sender: TObject; var Done: Boolean); begin Inc (IdleCalls) ; Sleep (10) ; Done := False ; end ; the app runs smoothly, the idle handler is called 100 times per second, and the CPU usage is next to zero. I then added a TActionList and connected up some controls to actions, coded an Execute and Update handler. procedure TMainForm.ActionNewButtonExecute(Sender: TObject); begin DoNewProject ; end ; procedure TMainForm.ActionNewButtonUpdate(Sender: TObject); begin ActionNewButton.Enabled :=
