Invoke Upload from link

I would like to invoke the upload dialog from a hyperlink on the page.  

For example, "click here to upload...")

(The FileVistaControl is already functinal on the page.)  

Is there any way to do this?

If FileVistaControl is already loaded on the page then you can call this javascript function in the onclick of your hyperlink:

executeCommand("Upload");

This call will invoke the upload dialog to upload files to the current folder.
