imports system.io imports microsoft.phone.tasks imports system.io.isolatedstorage imports system.windows.media.imaging  partial public class page1     inherits phoneapplicationpage      public sub new()         initializecomponent()         photochoosertask = new photochoosertask()         addhandler photochoosertask.completed, addressof photochoosertask_completed     end sub     dim photochoosertask photochoosertask     private sub photochoosertask_completed(sender object, e photoresult)         dim bmp system.windows.media.imaging.bitmapimage = new system.windows.media.imaging.bitmapimage()         bmp.setsource(e.chosenphoto)         image1.source = bmp         dim originalfilename = path.getfilename(e.originalfilename)         saveimage(e.chosenphoto, originalfilename, 0, 100)      end sub     public shared sub saveimage(byval imagestream stream, byval filename string, byval orientation integer, byval quality integer)         using isolatedstorage = isolatedstoragefile.getuserstoreforapplication()             if isolatedstorage.fileexists("newpics\filename")                 isolatedstorage.deletefile("newpics\filename")             end if              if not isolatedstorage.directoryexists("newpics")                 isolatedstorage.createdirectory("newpics")             end if               'isolatedstorage.createdirectory("newpics")             'dim filestream new isolatedstoragefilestream("filename", filemode.create, isolatedstorage)             dim filestream = isolatedstorage.createfile("newpics\" + filename)             dim bitmap = new bitmapimage()             bitmap.setsource(imagestream)              dim wb = new writeablebitmap(bitmap)             wb.savejpeg(filestream, wb.pixelwidth, wb.pixelheight, orientation, quality)             filestream.close()         end using     end sub     private sub button1_click(sender object, e system.windows.routedeventargs) handles button1.click         try             photochoosertask.show()          catch ex system.invalidoperationexception              messagebox.show("an error occurred.")         end try     end sub end class

can me making mistake?

the code perfect, problem silverlight uses "isolated storage" storing files, is, name implies, isolated storage. file or directory created application accessible application.

i think emulator storing isolated storage files in memory, since doesn't have keep them after restart. if want see inside application's isolated storage use tool wp7 explorer: http://wp7explorer.codeplex.com/
