Display dot-dot-dot progress in a WPF button

阅读更多关于 Display dot-dot-dot progress in a WPF button

I found quite a few examples for showing progress where the progress bars and wheels are used however; I could find only one javascript example to show an ellipsis (dot-dot-dot) to refer progress hence I thought of asking this question. My app is not very complex - it only has a few check-boxes and one button. Recently my team requested for an enhancement and want to keep it simple as well. There is a button named 'GO' that the user clicks after configuring the required settings. The code behind it is also really straightforward - it disables the button after the click event and call's a

Is there a 'Get Latest Version' preview in TFS? (Like VSS 'Get' command)

阅读更多关于 Is there a 'Get Latest Version' preview in TFS? (Like VSS 'Get' command)

My question relates to Team Foundation Server (TFS) and specifically, is there any way to know which files have changed on the server before doing a 'Get Latest Version (Recursive)? In Visual Source Safe (VSS), you could do a 'Get' (I think) which showed you all the files which were being considered for the update and which files we're changed on the server (an consequently would be updated during the get). This functionality seems to be completely missing! Also, when I do a 'Get Latest Version' in TFS, there doesn't seem to be any notification that any things occurred, other than the blur of

Are there progress update events in jQuery ajax?

阅读更多关于 Are there progress update events in jQuery ajax?

i have long running task that gets called using jquery ajax. i am using the block ui plugin to show "loading". is there anyway i can send progress messages back to the client to show progress and have that updated on the block ui plugin message. So it will show this (as the server does its work) . . "Loading first source . . . " "Loading second source . . . " "Loading third source . . . " "Parsing Results . . . " From what I've seen for the case of uploading stuff - people create a separate gateway and query it for progress info as it's only avaliable on the server side. But I think it's not

前端图片压缩上传

　在移动端压缩图片并且上传主要用到filereader、canvas 以及 formdata 这三个h5的api。逻辑并不难。整个过程就是：　　（1）用户使用input file上传图片的时候，用filereader读取用户上传的图片数据（base64格式）　　（2）把图片数据传入img对象，然后将img绘制到canvas上，再调用canvas.toDataURL对图片进行压缩　　（3）获取到压缩后的base64格式图片数据，转成二进制塞入formdata，再通过XmlHttpRequest提交formdata。　　如此三步，就完成了图片的压缩和上传。　　说起来好像挺简单，其实还是有些坑的。接下来就直接用代码进行分析：　　【一】获取图片数据　　先是获取图片数据，也就是监听input file的change事件，然后获取到上传的文件对象files，将类数组的files转成数组，然后进行forEach遍历。　　接着判断文件类型，如果不是图片则不作处理。如果是图片就实例化一个filereader，以base64格式读取上传的文件数据，判断数据长度，如果大于200KB的图片就调用compress方法进行压缩，否则调用upload方法进行上传。 filechooser.onchange = function() { if (!this.files.length) return
