Application: Reading Our Score DataWe’ll read the data containing our scores, and then display it.
Create the 'Try 5-3' ProjectClose the Try 5-2 project and then, from the IDE 'File' menu, select 'New Project'. In the 'New Project' dialog box, select “Applet Project” (1), input “Try5-3” (2), specify c:\Curl\lesson\Try5\03_score_file in the “Directory” field (3), set the API Version to 6.0 (4), and then click OK (5).
Inputting the ProgramCopy the c:\Curl\Try5\03_score_file\score.txt file to the c:\Curl\lesson\Try5\03_score_file directory. Next, we’ll input the program. You can copy the program code below or use c:\Curl\Try5\03_score_file\start.curl and then paste it into the editor in the IDE.
Code:
{value
let loc:Url = {url score.txt}
let in:#TextInputStream
let data-array:StringArray = {StringArray}
let record-set:RecordSet = {RecordSet
{RecordFields
{RecordField name, domain = String},
{RecordField age, domain = int},
{RecordField score, domain = int}
}
}
{try
set in = {read-open loc}
{until in.end-of-stream? do
{if-non-null line = {in.read-line} then
{data-array.append {line.to-String}}
}
}
catch e:IOException do
{popup-message Error reading file}
{output e.message}
finally
{if-non-null in then
{in.close}
}
}
{for data:String in data-array do
let array:StringArray = {data.split split-chars = ,}
{if array.size == 3 then
{record-set.append
{RecordData
name = array[0], age = {array[1].to-int}, score = {array[2].to-int}
}
}
}
}
{RecordGrid
record-source = record-set,
width = 10cm,
height = 3cm
}
}
