TCP send file - help

[System 0]

Hello,

I have got a problem with my "updateprogram" I'm writing on.

It should send a .exe-file over TCP. Well it does.. but the file has not the same filesize after Sending (the last time I tried I got the double filesize :-/) and of cause it's not working.

sender

CODE

Func _updatemode()

;select file

Local $File = FileOpenDialog("Bitte wählen sie die Datei aus", @DesktopDir, "client (*.exe)")

If @error Then

printSystem("update cancelled")

return

EndIf

Local $SplitBits=1024

Local $fileopen = FileOpen($File, 16)

Local $open = FileRead($fileopen)

;slize File

Local $len=Ceiling(BinaryLen($open)/$SplitBits)

Local $data[$len]

For $x=0 To $len-1

$data[$x]=BinaryMid ( $open, $x*$SplitBits+1 , $SplitBits )

Next
