Solution 1

Send your file with the content type "application/octet-stream" rather than "application/pdf". That way the browser will always treat it as a basic binary file and the only options it will give are to open or save.

Also as a basic rule "forcing IE to...." is never a solution for any problem. Your website can never override browser functionality, and what if they are not using IE but some other browser? There are usually ways to tackle these issues but trying to restrict the browser in its functionality is never one of them.

Hi thanx, i explain better my problem:
i'm working with webbrowser in c#, in this situation i must download some pdf files, (i dont explain now why i dont use webclient etc etc...) so the problem is that when i start the download the pdf is opened inside the browser or opening the reader, instead i need that starting the save file prompt.
The link does no have the explicit url (referred to file), so i also tried to add header content-disposition:attachment in the navigate method but it doesnt work, so i thought that one solution could be find the manner to say ie to show the prompt always, ...maybe with the appropriate registry key?

Any other solution would be appreciated.
Thanx
