Thank you so very much good people.
I am amazed each and every time from the kind people around here who are there to really help. Erel, you have build a wonderful community.
as for the topic :
right after the file creation , I send it to upload with ftp to a ftp server.
however, in the log I got "file not found"
I don't know why the binary god is so cruel to me, it's got to be something bad I did in the past.
maybe it's because I'm using an old slow phone as the emulator?
anyway, I tried "sleep(500)" in between and it worked fine! this is why I wanted to delay a bit or to loop until I'm positive that the file created and exists.
I've been told by smart people in the past to avoid the sleep command if I can.
so the
If File.Exists(.....) then worked just fine,
THANK YOU !
