8 public static bool Pdf2swf (string Pdfpath, string swfpath, int beginpage, int endpage, int photoquality)
9 {
//swftool, first install, and then copy the contents of the installation directory to the tools directory

SB. Append ("P" + "\" "+ Beginpage +" "+"-"+ EndPage +" "");
SB. Append ("-j" + photoquality);
String Command = sb. ToString ();
System.Diagnostics.Process p = new System.Diagnostics.Process ();
p.StartInfo.FileName = EXE;
P.startinfo.arguments = Command;
P.startinfo.workingdirectory = HttpContext.Current.Server.MapPath ("~/bin/");
P.startinfo.useshellexecute = false;
P.startinfo.redirectstandarderror = true;
