Android Question HH:MM to ticks ?

[Colin Evans]

Hi, I've looked in the forum and I'm sure it's a quick fix but I can't find a way of changing a time entry of say 12:30 to ticks
Anybody know the answer please

12:30 ist missing a Date. How would you convert it to ticks without?

With a little bit of string methods you can extract the hours and minutes.
Then

dim ticks as long = (12*DateTime.TicksPerHour)+(30*DateTime.TicksPerMinute)

Must be having a brain freeze, just added the date and now working wonderfully, thank you

Thought I'd sorted it but getting java.text.ParseException: Unparseable date: "05/01/2022 14:55"

newdate = "05/01/2022"
TimeFrom = "14:55"

DateTime.DateFormat = "dd/MM/yyyy hh:mm"

Dim tfrom As Long = DateTime.dateParse(newDate & " " & txtFrom.Text)

Any pointers on what I'm doing wrong

DateTime.DateFormat = "dd/MM/yyyy hh:mm"

Here is an example

DateTime.DateFormat = "dd/MM/yyyy"
    DateTime.TimeFormat = "HH:mm"   
    Dim newdate As String = "05/01/2022"
    Dim TimeFrom As String = "14:55"
    Log(DateTime.DateTimeParse(newdate,TimeFrom))

or:

DateTime.DateFormat = "dd/MM/yyyy HH:mm"
    Dim newdate As String = "05/01/2022"
    Dim TimeFrom As String = "14:55"
    Log(DateTime.DateParse(newdate & " " & TimeFrom))

    Dim newdate As String = "05/01/2022"
    Dim TimeFrom As String = "14:55"
    Log(DateTime.DateTimeParse(newdate,TimeFrom))

or:

DateTime.DateFormat = "dd/MM/yyyy HH:mm"
    Dim newdate As String = "05/01/2022"
    Dim TimeFrom As String = "14:55"
    Log(DateTime.DateParse(newdate & " " & TimeFrom))

Can't believe it was something so stupid that I missed, I've been putting hh instead of HH, thank you Mahres (and DonManFred), I'd tried all the various formats I could think of but always put hh, I've slapped my wrists and moving on, thanks again

To be fair, it probably worked fine each morning until stopping for lunch at 1pm. And then magically start working again at midnight or 1am. ?
