iOS Question Problem with DateTime

[WebQuest]

Hi guys I have a problem with DateTime I am trying to store a date in a variable for a long time and then use it but I get an error.

java.lang.NumberFormatException: For input string: "11:30"

I am using the code of my B4a app which works correctly but on B4i it does not work....

dim VarTime as long

DateTime.TimeFormat="HH:mm"

VarTime=DateTime.Time("11:30")

log(VarTime)

It also doesn't work in B4J. You need TimeParse.

    DateTime.TimeFormat = "HH:mm"
    Dim dt As Long = DateTime.TimeParse("11:30")
    Log(DateTime.Time(dt))

I'm working with B4i TimeParse is not present in the DateTime methods in B4i

 

[Semen Matusovskiy]

I am using the code of my B4a app which works correctly but on B4i it does not work....

It's impossible. DateTime.Time converts ticks to string representation of the time.

 

[WebQuest]

Sorry if I expressed myself wrong! the b4a code includes the DateTime.TimeParse method which on B4i is not present and I thought its equivalent was DateTime.Time .... Excuse my ignorance and little experience on B4i but I believed the methods were the same for B4j, B4a, B4i.

Does anyone know in B4i what is the equivalent method for (DateTime.TimeParse)?

 

[Semen Matusovskiy]

You can use DateTime.DateTimeParse
Android's DateTime.TimeParse ("11:30") is equal DateTime.DateTimeParse (DateTime.Date (DateTime.Now), "11:30")

I get this error. Can you give an example with DateTimeParse?

    Dim VarTime As Long
    DateTime.TimeFormat = "HH:mm"
    VarTime = DateTime.DateTimeParse (DateTime.Date (DateTime.Now), "11:30")
    Log (VarTime) ' Output (on my PC) is 1617561000000

 

[WebQuest]

Yes this does not cause errors but how do I get the string 11:30?

 

[Semen Matusovskiy]

Add following line:

    Log (DateTime.Time (VarTime)) ' Output is 11:30

 

[WebQuest]

this works fine thanks. One last thing for this thrend. How can I make a comparison in B4a I have used:

    If VarTimeNow<VarTime Then     
      'code'
    end if

 

[Erel]

Exactly the same.

I have a problem with DateTime (DateTime.now) always returns 01:00 instead of the current time! how do i solve?

i am using this code:

TimeNow = DateTime.Time(DateTime.Now)

 

[Semen Matusovskiy]

DateTime.TimeFormat = "HH:mm"
Log(DateTime.Time (DateTime.Now))

What output do you see ?

 

[WebQuest]

I keep getting this 1:00 output

 

[Semen Matusovskiy]

Do you run on iPhone ? What time IOS shows in status bar ?

 

[WebQuest]

The time of the iphone is correct.

With this code it now works:

TimeNow = DateTime.Now

 

[Semen Matusovskiy]

What works ?
DateTime.Now returns the current time represented as the number of milliseconds since 1/1/1970 00:00 UTC.
Meanwhile you told about human representation (01:00).

 

[WebQuest]

Sorry I didn't express myself well. At the moment I have solved all the problems mentioned above.
To convert a set date this code was fine:

    Dim VarTime As Long
    DateTime.TimeFormat = "HH:mm"
    VarTime=DateTime.DateTimeParse(DateTime.Date (DateTime.Now),"17:00")
    Log (DateTime.Time(VarTime))

To get DateTime.Now case 'A' works:

'Case A
VarTimeNow = DateTime.Now

'Case B this get '01:00'
VarTimeNow = DateTime.Time(dateTime.Now)
