This code is no longer needed. Use File.WriteBytes / ReadBytes. Write an array of bytes to a file and read a file into an array of bytes. Sub BytesToFile (Dir As String, FileName As String, Data() As Byte) Dim out As OutputStream = File.OpenOutput(Dir, FileName, False) out.WriteBytes(Data,

dim bytes() as Byte = File.ReadBytes(path, filename) If you need to have a string then you need to convert the bytes to base64 or hex. https://www.b4x.com/android/help/encryption.html#base64_encodebtos

This is a very old thread. It would be better to start a new thread and give more details on what you are trying to do. Normally the bytes received should be read in a separate sub. Here you should check the number of bytes you have received against the number you expect. Even if you send the numbe

You should be able to read the bytes from a binary file into an array and then as long as you know the length, type and endianness of each value you could pick them out into individual arrays and use ByterConverter to convert the bytes to concrete types.
link: File.ReadBytes - will read all bytes into an array. RandomAccessFile - provides access to the file bytes.

bytes is bytes, strings are bytes that have been "massaged" to appear a certain way. (just as an image is bytes that have been "massaged" to appear as an image. eg, a byte with a value of 0x02 is a perfectly valid value in an image, but it's not printable as text.) text files saved under certain o

You can use RandomAccessFile.Initialize3 for this.

No. Better: Dim b() As Byte = Bit.InputStreamToBytes(inputstream) BytesAvailable is only an estimation and can return less than the complete size.

If you can read a set number of bytes, then is no problem to collect those chunks into lines, and I'd be surprised if there isn't already public code to do that. Lol, having said that: I'm going to look for it now, and I'm mildly worried I'm in for a surprise. ?

it has no idea what you had to go through to create a packet of zmodem data. tcp is at work on both sides of the connection. tcp on your side tells the other side what's coming. tcp on the other side verifies or asks for retransmission. this occurs more than once for each packet. reading bytes
