B4J Question [SOLVED][JStringFunctions] .DayOfMonth(), Fails in B4J?

Dadaista · Nov 28, 2017

Hi

Today is november 28

B4X:

sAux2 = sf.DayOfMonth (sf.Today())

Above line returns 11.. it seems return month?

This is the sub:

B4X:

Sub sNombreFichero As String
    Dim sAux As String
    Dim sAux2 As String
    sAux = sf.Year (sf.today())
    sAux2 = sf.Month (sf.Today())
    If sAux2.Length = 1 Then sAux2 = "0" & sAux2
    sAux = sAux & sAux2
    sAux2 = sf.DayOfMonth (sf.Today())
    If sAux2.Length = 1 Then sAux2 = "0" & sAux2
    sAux = sAux & sAux2
    Return sAux
End Sub

It returns "20171111"

The same sub works In B4A

Could you not use DateTime for the functions?
ie,

B4X:

...
    Dim now As Long = DateTime.Now
    Log(DateTime.GetDayOfMonth(now))
    Log(DateTime.GetMonth(now))
    Log(DateTime.GetYear(now))
..

if you wanted yyyyMMdd then you can use

B4X:

DateTime.DateFormat = "yyyyMMdd"
Log(DateTime.Date(DateTime.Now))

Don't forget to save the original DateFormat in a String , so you can set it back to default.

B4X:

Dim oldFormat as String = DateTime.DateFormat
' do your work here
DateTime.DateFormat = oldFormat
...

Don't use jStringFunctions or StringFunctions libraries. They are not maintained and all the features are available with the core libraries.
