This is the discussion thread for Episode 4 of QB64 Report, which is now available.

🔊 This time we talk to @luke, who's one of QB64's developers, and learn a lot about TCP/IP communications and networking in QB64.

Check it out at http://podcast.qb64.org and also in all major podcast providers.

I'll share the YouTube version here soon.

These are the samples discussed in the episode:

Code: QB64: [Select]

1. '-------------------------------
2. 'Sample 1: Simple HTTP request
3. h& = _OPENCLIENT("tcp/ip:80:alephc.xyz")
4. s$ = "GET /test.txt HTTP/1.0" + CHR$(13) + CHR$(10) + CHR$(13) + CHR$(10)
5. PUT #h&, , s$
6.  
7. s$ = ""
8. WHILE s$ = ""
9.     GET #h&, , s$
10. WEND
11. PRINT s$
12. CLOSE #h&

Code: QB64: [Select]

1. '-------------------------------
2. 'Sample 2: Split request
3. '-------------------------------
4. h& = _OPENCLIENT("tcp/ip:80:alephc.xyz")
5. s$ = "GET /test.tx"
6. PUT #h&, , s$
7. s$ = "t HTTP/1.0" + CHR$(13) + CHR$(10) + CHR$(13) + CHR$(10)

3. '-------------------------------
4. host& = _OPENHOST("tcp/ip:9991")

6.     c& = _OPENCONNECTION(host&)
7.     IF c& < 0 THEN

@luke definitely gets the Tim Berners-Lee award.  It is amazing that QB64 can do all that stuff.  (It's all a bit beyond my skill level, I think that I'll be sticking with _MAPTRIANGLE).
