why does this fail?

| I cannot remember how to do code blocks. But i tried to do this multiple ways. After and If statement, or in a subfunction the writeline stream, chr$(13) does not work. This sends a blank line to a text base mud that I play that uses ansi. And i cannot seem to figure it out. Any suggestions. The one that its set for under the comment works and repeatedly hits enter at the menu. the one in the if then fails. Graphics3D 800,600,16,2 Global stream Global msg$ Print "Test server starting up...." ;Stream=OpenTCPStream("10.0.0.2",4000) stream=OpenTCPStream("dsl-mud.org",4000) If stream Then Print "*Connected*" Else Print "failed to connect..." EndIf Print "running WriteLine stream,"no" p.player=New player p\stream=stream WriteLine STREAM, Chr$(13) While Not KeyHit(1) For p.player = Each player If ReadAvail(p\stream) Then ;While ReadAvail(STREAM) Print "reading" msg$=ReadLine(p\stream) Print msg$ ;n=ReadByte(stream) ;Print Chr$(n) ;Print n ;WaitKey() ;Wend EndIf ;this one works..... WriteLine p\stream, Chr$(13) If KeyHit(57) Then ;;;none of the next 3 work at all WriteLine p\stream,Chr$(13) ;writeline stream, chr$(13) ;writeline p\stream, "" Print "writing" EndIf Next Wend End Type player Field stream End Type |

| writeline stream, chr$(13) writes two empty lines. Instead writeline stream,"" writes just one linebreak, which may or may not be understood as a linefeed by the server. I think http protocol servers expect chrs 10 as linebreaks, no? |

| Ahh that could help. However the qriteline in the while/loop works fine. But the writeline in the if/then fails. Also it will not work in a function either. Anyway I try it. |

| You would be better using writebyte if you just want to send a single byte as writeline terminates the string with two bytes. |

| per the Blitz3D docs on WriteLine Each line of text is automatically terminated with an "end-of-line" mark, consisting of a Carriage Return character followed by a LineFeed character. (i.e. 0Dh, 0Ah ) So when you use WriteLine, you send your explicit Chr$(13) and B3D adds a Chr$(13)+Chr$(10). If you need to write one, and only one CHr(13), you are better off using WriteByte Stream,13 if expecting 8 bit characters or WriteShort Stream,13 if expecting 16 bit characters. (No need for the Chr$() in this instance). |
