See more JSON Examples

Demonstrates how to write a JSON array to a Chilkat StringBuilder object.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

integer li_rc
oleobject a
integer li_Success
string s
oleobject loo_Sb

a = create oleobject
// Use "Chilkat_9_5_0.JsonArray" for versions of Chilkat < 10.0.0
li_rc = a.ConnectToNewObject("Chilkat.JsonArray")
if li_rc < 0 then
    destroy a
    MessageBox("Error","Connecting to COM object failed")
    return
end if
li_Success = a.Load("[ 1,2,3,4 ]")

// We could get the JSON array as a string...
s = a.Emit()
Write-Debug s

// But what if the JSON array contains a huge amount of data,
// and we don't want to marshal it all from Chilkat's internal
// native code to a string in our programming language?

// You can instead emit to a Chilkat StringBuilder
loo_Sb = create oleobject
// Use "Chilkat_9_5_0.StringBuilder" for versions of Chilkat < 10.0.0
li_rc = loo_Sb.ConnectToNewObject("Chilkat.StringBuilder")

a.EmitSb(loo_Sb)

// Perhaps the StringBuilder object can be passed to other methods..
// Chilkat typically provides methods where a potentially large string
// can be passed in via a StringBuilder object..

// Or perhaps you wish to save to a file..
li_Success = loo_Sb.WriteFile("c:/temp/qa_output/a.json","utf-8",0)
