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
