No, the IDE says nothing:

Public Sub Test()

  Dim strinchar As String
  Dim psotionlen As Integer

  ' - 1
  strinchar = "strat)edn1"

  strinchar = Mid(strinchar, 1, InStr(strinchar, "u", -1) - 1)

  Print strinchar

  ' - 2
  strinchar = "strat)edn1"

  psotionlen = InStr(strinchar, ")", -1) - 1
  strinchar = Mid(strinchar, 1, psotionlen)

  Print strinchar

  ' - 3
  ' but the only thing this does is (AFAIK)

  strinchar = "strat)edn1"

  Print Left(strinchar, Len(strinchar) - 1)

End

Result is:

strat)edn
strat)edn
strat)edn

:-)

Maybe you should write and code a little slower. ;-)

[Gambas-user] Serialization Database query result

Hello.

What is the possibility to serialize the result of a database query 
(data type result)?

Every idea and approach is welcome.

Sincerely
Hans

jajaja excelent work!



Which Gambas version are you using ? There may be an old bug here.


3.9.1 with some git patches..

It's difficult to say for sure what's happening without Piccaro's test
strings.  However, 2 things do come to mind.

First, according to Gambas doc, InStr(strinchar, ")", -n) does a left to
right search for ")", starting at -n  characters from the end of
strinchar.  So if Instr doesn't find ")", it will return 0, which, in
conjunction with the second -1, will cause mid to drop the last character
of strinchar.  So to get the answer you want, use RInstr(strinchar,")").
which will do a right to left search for ")", starting at the end of
strinchar.

Second, there may be a bug in gambas, or the documentation needs to make
clear what end of string means.  This is best explained by example:

Instr("(foo)",")",-1) returns 5
Instr("(foo)f",")",-1) returns 5
Instr("(foo)ff",")",-1) returns 0

This means that Instr(s1,s2,-1) begins its search one character before the
last character of the string.  So end of string actually means last
character of the string and the docs should make that explicit or there is
a bug if the intended meaning of end of string is the position after the
last character of the string.

Piccoro, sorry for my previous information. Something was missing.
In fact, both versions work the same:












*  strinchar = "test )after)r"positionlen = (InStr(strinchar, ")", -1)
- 1)Print strincharPrint positionlenstrinchar = Mid(strinchar,
1, positionlen) Print strincharstrinchar = "test )after)r"
strinchar = Mid(strinchar, 1, (InStr(strinchar, ")", -1) - 1))Print

Both print  "test )after"

No... again. My initial mail was correct. It should be:


strinchar = Mid(strinchar, 1, (InStr(strinchar, ")", -1) - 1))

But the IDE makes highlighting bug with the brackets.

IDE said error invalid argument, but if i do:

   strinchar = Mid(strinchar, 1, psotionlen)

works, why?

i wnat to remove the last occurence of a char but bybass some
possible
spaces/chars at the end of string

[Gambas-user] [Gambas Bug Tracker] Bug #1130: JSON.Encode serializes null objects as "undefined"

2017-07-29 Thread bugtracker 
http://gambaswiki.org/bugtracker/edit?object=BUG.1130=L21haW4-

Adrien PROKOPOWICZ reported a new bug.

Summary
---

JSON.Encode serializes null objects as "undefined"

Type : Bug
Priority : Medium
Gambas version   : 3.9.90 (TRUNK)
Product  : Web components


Description
---

See example code here : 
https://gambas-playground.proko.eu/?gist=b70e4b4d0d25d56ba10b1d1ddb6ebfea

If I give JSON.Encode() a Null value (or Variant) it correctly serializes it as 
`null`.
However if I give it a Null object reference, it gets serialized as 
`undefined`. 

Which is surprising, but more importantly it is incorrect as there is no 
`undefined` in JSON.
