问题 I can't find any docs about creating dojox/form/Uploader programmatically.

问题 I know this may sound relatively basic question, but still wanted to ask. I need to upload two files at once by creating two file input in my form one for each file. Until now I have used a basic script for testing to upload a single file. I also found some examples how to upload muliple files, but in my case I am having two upload fields and I want the user to upload the two files. Once uploaded I wanted to save it onmy webserver. Any simple example would be of good help. Thanks 回答1: It's

问题 I have a form which has a FileField among other fields. Imagine the user chooses a file, presses submit and another field triggers a ValidationError. When I get back the form, with the errors on the page, what the user chose for the file field is gone. Can I make it appear, or is this a browser thing? 回答1: This is a browser thing - for security reasons, you can't prepopulate a file input, otherwise it would be easy to trick users into uploading files from their system without their explicit

问题 I am trying to upload a file in my GAE app. How do I the upload of a file in Google App Engine using Go and using the r.FormValue() ? 回答1: You have to go through the Blobstore Go API Overview to get an idea and there is a full example on how could you store & serve user data on Google App Engine using Go. I would suggest you to do that example in a completely separate application, so you'll be able to experiment with it for a while before trying to integrate it to your already existing one.

问题 Hey, I've got this nice little piece of code, much like all the other versions of this method of upload using WSS WebServices. I've got one major problem though - once I have uploaded a file into my doc list, and updated the list item to write a comment/description, the file is stuck there. What I mean is that this method will not overwrite the file once I've uploaded it. Nobody else out there seems to have posted this issue yet, so .. anyone? I have another version of the method which uses a

问题 I'm looking for a way to pause or resume an upload process via C#'s WebClient. pseudocode: WebClient Client = new WebClient(); Client.UploadFileAsync(new Uri("http://mysite.com/receiver.php"), "POST", "C:\MyFile.jpg"); Maybe something like..
