This library causes ERROR and i confirmed it

Damaged parameter of string type
 

my code

CJAVal  jv;
string text="abc";

jv.Deserialize(text);

Any idea how to fix it?

It only causes when i desearilize any string

If the string value does contain ';' character then Deserialize fails!

array out of range in 'JAson.mqh' (205,13)

Than you . I am sending POST WebRequests (http) from MT5 (MQL5) to Chat GPT-4-o-mini API (openai.com) . OpenAI receives JSON data . MQL does not support JSON . So had to covert to string, then convert string to Char[] array, to insert as postData into the WebRequest . I am using your Library, I'll let you know how I get on

That is awesome
I was thinking the same to feed my ML with response from ChatGPT.
Mind sharing how do you did it? What are the challenges?

Thanks!

Hi, is there any way to:

- Set the value of a key to null 

- Set the value of a key to {} (empty object) 

It seems that those values won't get correctly represented if you try to set them.

Thanks for any reply
