Argument

Description

objectname

The name of the JSONParser or JSONPackage object to which the JSON file will be loaded.

Examples

This example loads a JSON file into the JSONParser object:

String ls_Error
JsonParser lnv_JsonParser
lnv_JsonParser = Create JsonParser

ls_Error = lnv_JsonParser.LoadFile("c:\employee.json")
if Len(ls_Error) > 0 then
 MessageBox("Error", ls_Error)
end if

This example loads data from the employees.txt file and then loads the "d_employee" data into the DataWindow:

string ls_EmployeeJson, ls_Error
JsonPackage lnv_package

lnv_package = create JsonPackage

ls_Error = lnv_package.LoadFile ("d:\temp\employees.txt")
if Len(ls_Error) = 0 then
	ls_EmployeeJson = lnv_package.GetValue("d_employee")
	dw_1.ImportJson(ls_EmployeeJson)
else
	Messagebox("Error", ls_Error)
end if
