Universal Date Format Conversion

4 posts in this topic

This is an example of a universal date converter from your PC local date format to any format you could need to use.

I couldn't find any good solution on the forum, so I re-engineered an example of DaRam.

This should work with any regional setting date format.

The script reads the Local date format in your registry setting.

RegRead("HKCU\Control Panel\International", "sShortDate")

I hope you can use it.

    Description:    Universal date format converter
                    Converts the (default regional setting) PC Date format into any other specified date format:
                    - convert date into another date format (for example ddd dd MMMM, yyyy)
                    - convert date into day (d or dd)
                    - convert date into month ( m, mm or mmm)
                    - convert date into year (yy or yyyy)
            
    Parameter(s):   $InputDate  Input date 
                    $DateFmt        - Format of input date (optional), if omitted, will return date in mm/dd/yyyy

    Requirement(s): <DateCalc.au3>
                    The udf is included in this script 
    
    Return Value(s):On Success      - Date in in requested format
    
                    On Error        - @ERROR 1 (input date badly formatted)
                                    -  Error Message

    Syntax:         DateFormat( $Date , $DateFormat )
    
    Example:        DateFormat( _NowCalcDate() , "dd-MM-yyyy" )

#ce
#include <Date.au3>
#include <DateTimeConstants.au3>
#include <GUIConstants.au3>
;#include <DateCalc.au3>

Global $sDateFormat = RegRead("HKCU\Control Panel\International", "sShortDate") ; This is the date format of your PC

; example 1: Using GUICtrlCreateDate in a GUI
$Form1 = GUICreate("PC DateFormat: " & $sDateFormat, 290, 112, 193, 115)
$Label1 = GUICtrlCreateLabel("Date:", 8, 8, 90, 17)
$Input1 = GUICtrlCreateDate(_Date_Time_GetLocalTime(),  100, 8, 180, 21,$DTS_SHORTDATEFORMAT ) ; $DTS_SHORTDATEFORMAT $DTS_LONGDATEFORMAT

$Label2 = GUICtrlCreateLabel("Date Time Format:", 8, 36, 90, 17)
$Input2 = GUICtrlCreateInput("ddd dd MMMM, yyyy", 100, 33, 180, 21)
$Button1 = GUICtrlCreateButton("&Convert", 8, 64, 89, 25, 0)
$Input3 = GUICtrlCreateInput("", 100, 64, 180, 24)
GUISetState(@SW_SHOW)

GUICtrlSetData( $Input3, DateFormat( GUICtrlRead($Input1), GUICtrlRead($Input2) ) )

While 1
    Switch GUIGetMsg()
    Case $GUI_EVENT_CLOSE
         ExitLoop
    Case $Button1
         GUICtrlSetData( $Input3, DateFormat( GUICtrlRead($Input1), GUICtrlRead($Input2) ) )

ConsoleWrite ( DateFormat( $Date , "MMM" ) & @CR)
ConsoleWrite ( DateFormat( $Date , "d" ) & @CR)
ConsoleWrite ( DateFormat( $Date , "yy" ) & @CR)

Ah, very nice. This will come in handy; I've had to do lots of date conversion.

This will make it easier, well done.
