Hello
my be is my error, but I am unable to send more of one file whith PostMultipart.
Obviusly my File list contains more than one file, but only the last is sent.
Instead I corrected in: If pictures.size > 0 Then
For i = 0 To pictures.size - 1
Dim filePath As Map = fg.pathinfo(pictures.GetKeyAt(i))
Dim fl As MultipartFileData
fl.Initialize
...
And all pictures was sent.
