vb.net - Why won't this write to my text file in Visual Basic? -

i have been trying , searching hours , telling me doing, why won't code write text file? no errors being thrown, data won't write

dim newday boolean = true dim attendance streamwriter     if newday = true         try             attendance = file.appendtext("attendancelog.txt")             attendance.writeline(date.today.tostring("dd/mm/yyyy"))             newday = false         catch             messagebox.show("file access denied", "error")         end try     end if 

when using streamwriter, send put in queue avoid writing file everytime new part needs appended (which inefficient large files logs).

to process queue, call streamwriter.flush().

but discouraged. should instead use streamwriter.close() @ end, automatically , disposes object memory, too.

dim newday boolean = true dim attendance streamwriter if newday = true     try         attendance = file.appendtext("attendancelog.txt")         attendance.writeline(date.today.tostring("dd/mm/yyyy"))         attendance.close()         newday = false     catch         messagebox.show("file access denied", "error")     end try end if
