I am trying to resolve a situation like this: when the user, in the web-clinet, press a button a spreadsheet document will be generated in background and when it is done the user will select the path to save it on his PC with the FileDialog. I have tryied with BeginCopyingFile, MoveFile but is not working. If I use the standard command of the spreadhsheet it wil freeze the browser when the document is too big (and here is more time to wait to display it on the interface) and I want to avoid this case.
Please tell me if you know.
