My modifications read vars without the type on a string that contains numbers. The JSON String:
Code: Select all
{"ffloatnumber":0.5,"fnumberNullDotNull":0.0,"fnumberten":10,"fonenull":null,"frawfalse":false,"frawtrue":true,"frawtxt":"rawtxt","ftxtnumber":"1234567890"}- oStr.frawtrue=true
oStr.frawfalse=false
oStr.fonenull=null
oStr.fnumberten=10
oStr.fnumberNullDotNull=0.0
oStr.ffloatnumber=0.5
oStr.ftxtnumber=1234567890 <==== this is a string that contains numbers
oStr.frawtxt=rawtxt
In general its better the read function load the vars with quotes if there ones.
testing code:
