I found a way to do this, but you need to use User32.dll sendmessage() function, after you press button\link and you have your download dialog i use sendmessage to send key's i send:

1- (F6) it will select the download dialog.

2-(Tab) -it will select the first option Save.

3- (Enter) will press Save button that will save file to deafault derectory

4- For 100% i check in registry the defeaul folder of IE and easy find my file and copy it to directory that i need.

Why i use sendmessage and not sendKey?

Answer: sendmessage will still press on buttons even if windown is lock no need UI.
