B4J Question date format handle webserver

[Roberto P.]

I noticed that if I set the date format in the main, when you log on to the various handle is used another format.

I set, in the main the following format

DateTime.DateFormat    =    "dd/MM/yyyy"
Log("main date format " & DateTime.DateFormat)

for example, if I enter the smyle handle, I see that the formatting is different?!

How can I set a date format that is automatically seen by all handles?

thank you

I attach example.

Changing the DateFormat is done on a per-thread basis. When you change the DateFormat in your Main module, that is most likely executed on the Main thread and so only applies on the Main thread. You have a couple options: 1) run all your Handlers as single-threaded (they'll run in the Main thread and use the Main thread's DateFormat) or 2) set the DateFormat in each Handler.

Option 2 can be quite simple: just create a Global String in Main called dfString = "dd/MM/yyyy" and do this in the Initialize method of your Handlers (and WebSockets):

DateTime.DateFormat = Main.dfString

I thank you, I would avoid the second option, and find out how to set the date format for all threads without having to set for all handles.

You can write a simple global method to do the same.. as clever as you want (pass in date, format it and pass back, set it to original format before exiting method)

Dim df As String = DateTime.DateFormat  ' save the last known (default) date format
DateTime.DateFormat = "MMM dd, yyyy"
' mod your date vars - then change it back
DateTime.DateFormat = df

df = default format (ie. "yyyy-MM-dd")

At times I need to change it to show full text (January 12, 2017), and then I want to reset it to default (2017-01-12). Set a global as default, and when in doubt if your default is correct, call before setting (recording) and date with DateTime.DateFormat = Main.df...

Hi Harris,
thanks you for answer.

It is what I did.

I ask is if there is a way to set my format (Italian = dd / mm / yyyy), without having to set the default for each handle?

Thank you

No. You will need to set it in each handler.

No. You will need to set it in each handler.

ok, thanks you
