Hi,
I need to write a control to upload the pictures. When user browses to select the pictures on the local computer, it allows you to select multiple files. Can you tell me how I can do it, please? I think it might be Java applet or somethings like that. .NET controls might be difficult to select multiple files. Thank in advance, Duc |

"Control" is emasculated M$-ese for a "widget", I suppose...
Anyway, there are no widgets in html, really, just form elements; and the file selection has to be done by the user, for obvious security reasons, so you don't need to, and indeed can't do anything about it. |

You might misunderstand me. The selection is certainly done by user. This user control's functionality should look like Windows Explorer which user can select multiple files.

If I understand correctly now, this is a MS-Windows programming issue, then? Nothing to do with html, really, let alone server-side scripting? Perhaps you need to try an MS-Windows programming forum? Or perhaps, as you say, you hope to write a Java applet, that you include in the page, and it just handles the file upload? (Ah, how "convenient"... M$-thinking at its purest!) Well, basically you can't, because I the archetypal user don't trust your (or anyone else's) website with access to my file system. Here's a sample page about this: http://www.duckware.com/applets/reference.html (section 2: Security) HTH |

A more robust approach is to have a submit button on the original form that adds another file input element. The server-side program returns another copy of the form, this time with an additional file input element.

Why not have several INPUT type="file" from start? The way many "file managers" have it.

Check Ajax Uploader.
It allows you to select multiple files and upload multiple files at once. http://ajaxuploader.com/Demo/select-multip...les-upload.aspx |
