maybe this could work (xp only?):
code:
function SaveFile(){
var SFD = new ActiveXObject("SAFRCFileDlg.FileSave");
SFD.FileName = "*.*";
SFD.FileType = "*.*";
if(SFD.OpenFileSaveDlg()){
return SFD.FileName;
}
return false;
}
run this JS script in wscript.exe. since it uses the jscript scripting engine, it works
