upload

问题 I'm working over a sketch to enable uploading from an Android device to an Arduino board, and it works for Duemilanove (FTDI-based) and Arduino Uno (ATmega-based) when testing for PC/Arduino using rxtx (pure Java). But it does not work when using the USB-Android library as the setDTR/setRTS methods are not yet implemented. FTDI Android drivers allow the sending of setDTR/setRTS signals, but it fails to send/read data after it. So the problem is in the Android USB API and I can't figure out

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How do you loop through $_FILES array? For some reason arrays really get to me. I can get there in the end, but this $_FILES array seems to be backwards to me. I want to be able to loop through $_FILES like so: foreach($_FILES as $file) { echo $file['name'] . "<br>"; echo $file['type'] . "<br>"; echo $file['size'] . "<br>"; echo $file['error'] . "<br>"; } But obviously with the way its structured you cannot do

问题 As far as I know IIS and ASP.NET has a limitation of 2Gb files upload. Are there any solutions for this in IIS 7.5 and .Net 4? 回答1: I found a blog post that explains the cryptic error "ASP.NET detected invalid characters in the URL." From the blog post: When the integrated pipeline is used, we go though webengine code (webengine4!MgdGetRequestBasics) which doesn't support more than 2 GB content-length and a System.ArithmeticException exception is raised which subsequently cause the HTTP 400

问题 It can be related to Webfaction configuration (they have nginx proxy, and my app is webpy running under apache2+mod_wsgi) because it works in my dev cherrypy server. Here are some bits from javascript code I use for upload: /* Bind drop events */ $(this).bind({ "dragover": function(e){ var dt = e.originalEvent.dataTransfer; if(!dt) return; if($.browser.webkit) dt.dropEffect = 'copy'; $(this).addClass("active"); return false; }, "dragleave": function(e){ $(this).removeClass("active") },

问题 I have a Spring MVC web with two different pages that have different forms to upload different files. One of them should have a limitation of 2MB, while the other should have a 50MB limitation. Right now, I have this limitation in my app-config.xml: <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- one of the properties available; the maximum file size in bytes (2097152 B = 2 MB) --> <property name="maxUploadSize" value="2097152 "/>

问题 I am trying to upload large files video files to Facebook, but regardless of the approach taken, the result is always the same. The process uploads between 5-35mb worth of data then times out. This happens on WiFi. I have tried with the Facebook SDK 3.1.1, iOS Social Library (i.e. SLRequest) and AFNetworking. The social library and afnetworking give time out errors, whereas the Facebook SDK just returns a Code 5, Operation Could Not Be Completed, HTML Error 200 but if I watch the network

问题 So i have watched the 5 part youtube videos by David Mosher about Angular JS (vids great by the way). In the part 2 (http://www.youtube.com/watch?v=hqAyiqUs93c), it has a practical mysql database usage which I almost wanted. I'm going to use AngularJS along with Laravel 4, but I had no idea which files I'm going to upload for the web hosting later . I'm trying to run the web app under "/public" folder in my root on localhost (localhost/public/) but the css and js points to the wrong directory

问题 I'm using a single image upload/crop/resize script for files up to 10MB. When testing, I set php_ini memory limit to 25M and that is exhausted when uploading a file only about 1.4MB. "Allowed memory size of 26214400 bytes exhausted (tried to allocate 10368 bytes)" This seems strange to me, isn't 10368 < 26214400? (Rhetorical Question) Or does that mean I went 10368 bytes over 25MB? Should my script be using this much memory? Code: function make_thumbnails($updir, $img) { $thumbnail_width =

问题 I'm trying to have a button to allow users to upload a file, into a specific folder. I tried to follow other advise, and add this hook to onPickerInit: var uploadView = new google.picker.DocsUploadView() uploadView.setParent('XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'); // test folder pickerBuilder.addView(uploadView); I've set the MULTISELECT_ENABLED feature (without it, the destination folder is not respected), and I can in fact now upload the files where they belong. Yay! HOWEVER: The picker
