is it possible to resize/hide Window Standard Dialog ("choose file to upload" window)?

The "choose file to upload" window which pops up when the browse button is clicked in the file input element on a web page.

Is it possible to hide/resize this "choose file to upload" window using user32 lib functions like ShowWindow etc. I tried using ShowWindow by provi开发者_JAVA技巧ding the handle of the "choose file to upload" window but it didn't work.

Is it possible to work on this windows? If yes, how can I do it?

As an alternative you could try http://www.plupload.com/ which bypasses the need to open the file chooser windows and instead uses HTML5 or Flash to upload.
