GetBytes Problem

[rbsoft]

In the following piece of code the value Chr(254) is not properly translated.

t = "&&ID|" & MyIP & "|1|42" & Chr(254)
Buffer = t.GetBytes("UTF8")
OutputStream1.WriteBytes(Buffer,0,t.Length)

The receiving program gets everything right except that Chr(254) has changed into Chr(195).

Any idea what I am doing wrong?

PS:
Just noted in the Debugger that Chr(254) gets translated into Chr(-61) & Chr(-66). Number of bytes became 21 instead of 20.

Chr 254 translated to unicode is two bytes C3, BE, or 195, 190 in decimal. These values translate to -61, -66 as signed 8 bit integers so things are working as they should.

Not sure what you are doing, but it seems that you need to use different encoding.

I use Chr(254) as an end delimiter in a TCP/IP protocol I am using for many years.

I tried UTF16 and ASCII encoding but without success.

Why not send the byte 254 instead of first converting it to string?

 

[rbsoft]

How would I do that? Could you give 2 or 3 lines of code?
Somehow I am not able to grasp it.

You can send a single byte by calling:

OutputStream1.WriteBytes(Array As Byte(254), 0, 1)

Thank you, Erel.

Yep - that did the job! My communication routines work.

Thanks also, kickaha, for the information.
