How to get previous date from a string

Recommended Posts

ur

I have date in the string format as "DD-MM-YYYY".

 

I need to get yesterday's date from it.

I tried converting this from _DateTimeFormat but not working.

Is there any direct UDF available to get this.?

Oh!! Thanks @jguinch

Unnecessarily, I created below logic in the meanwhile.

Func yeterdayDate($sDate)

$f =  StringSplit($sDate,"-");StringSplit("22-01-2018","-")
_ArrayDisplay($f)
if $f[1]>1 then
    $f[1]-= 1
Else
    If Number($f[2])-1 =1 or Number($f[2])=3 or Number($f[2])=5 or Number($f[2])=7 or Number($f[2])=8 or Number($f[2])=10 or Number($f[2])=12 Then
        $f[1]=31
    ElseIf Number($f[2] - 1) < 1 Then
        $f[1]=31
        $f[2]=12
        $f[3]=Number($f[3])-1
    Else
        $f[1]=30
    EndIf
EndIf

padZero($f[1])
padZero($f[2])
padZero($f[3])

;MsgBox(0,"",$f[1]&"-"&$f[2]&"-"&$f[3])
return $f[1]&"-"&$f[2]&"-"&$f[3]

EndFunc

Func padZero(ByRef $sValue)
    if Number($sValue)<10 Then
        $sValue = "0"&Number($sValue)
    EndIf
EndFunc

#Include <Date.au3>

Local $sDate = "01-01-2018"
Local $sDatePreviousDay = _DateAdd("D", -1,  StringRegExpReplace($sDate, "(\d{2})[/-](\d{2})[/-](\d{4})", "$3/$2/$1") )
ConsoleWrite($sDatePreviousDay)

      This is another take on string triggers, triggers on specific strings.
      Able to simple text pasting,
      opening links (as long as there's a www. http:\\ or https:\\ at the beggining)
      and is able to open applications, if there is a parameter in the parameter field, it uses it.
      The user selects the modifier key, and then uses a combination of that key with a couple others to perform tasks like
      screenshot the active window, (modkey + prtscr), turn off the screen (modkey + pause / break),
      open clipboard string in registry (modkey + R), change system volume (modkey + arrouw up/dn).
      The following keys pressed at the same time prompt for shutdown: S+D+T
      The following keys pressed at the same time prompt for restart: S+R+T
      Middle mouse button click on titlebar minimizes to tray, or a left mouse button click in the icon in the tray also minimizes.
      Trigger is set off by space or enter, and timeouts after 3 seconds.
      Shows your external, lan, and gateway ip's, can refresh with right mouse click, and opens the default browser if the correspondent button is pressed.
      Able to change system volume by a set percentage, reading from the inputbox the number the user sets, if 0 or empty uses system default.
      I made this because the existing string trigger applications didn't do it for me for a number of reasons.
      I did this for me, but if someone finds it useful all the better.

      Here is an other UDF for string handling :
      Date handling
      _StringDateConvert:  convert a date from one format ("YMD", "MDY" or "DMY") to another.
      _StringIsDate:  checks if a date with a given format is valid
      String management
      _StringCount: count of occurrences that appear in a string
      _StringFormatBytesSize: formatting a dimension expressed in bytes (bytes) in MB, TB, ...)
      _StringIsEndingWith: check if a string end with some characters
      _StringIsStartingWith: check if a string start with some characters
      _StringJoinArray:  concatenate elements of an array to rebuild a string
      _StringPadLeft: filling a string with characters on the left
      _StringPadRight: fill a string with characters on the right
      _StringRemoveFrenchAccent: remove french accent
      _StringRemoveChars: deleting characters from a string
      _StringStrip: eliminate characters at the begin and/or at the  end of a string
      _StringTitleCaseFrench: capitalize the first letter of each word with elimination of french accents
      _StringWSClean: simple replacement of "White Spaces",  remove beginning and trailing spaces and multiple spaces removal
      Any comments, suggestions for improvement or constructive criticism are welcome.
      Below you will find the UDF and a demo program.

      Hey All,
      I'm trying to set the date using a variable.
      Basically, I set the date into the input box, then I change the input box, say, I change the year.
      Then I set what I typed into the input box into the Date Picker.

      This is a demo code.
      #include <ButtonConstants.au3> ;Start GUI includes #include <EditConstants.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include <DateTimeConstants.au3> #include <GUIConstantsEx.au3> #include <GuiDateTimePicker.au3> #Region ### START Koda GUI section ### Form= $Form1 = GUICreate("Form1", 615, 438, 192, 124) $Date1 = GUICtrlCreateDate("2019/02/02 23:16:26", 80, 64, 186, 21, $DTS_SHORTDATEFORMAT) $Input1 = GUICtrlCreateInput("Input1", 80, 152, 185, 21) $Button1 = GUICtrlCreateButton("Set data", 176, 96, 75, 25) $Button2 = GUICtrlCreateButton("Read from input", 176, 200, 75, 25) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 $Read = GUICtrlRead($Date1) GUICtrlSetData($Input1, $Read) MsgBox(-1, "", $Read) Case $Button2 $Read = GUICtrlRead($Input1) $New_date = StringReplace($Read, "/", "") $DAY = StringLeft($New_date, 2) $MON = StringMid($New_date, 4, 3) $YEAR = StringRight($New_date, 4) MsgBox(-1, "", $DAY & $MON & $YEAR) ;_GUICtrlDTP_SetFormat($hWndDate, "yyyy/MM/dd") $DateFormate = ($DAY & " " & $MON & " " & $YEAR) $DTM_SETFORMAT_ = 0x1032 ; $DTM_SETFORMATW GUICtrlSendMsg($Date1, $DateFormate, 0, "MM/dd/yyyy") EndSwitch WEnd

      Hello all! I hope everyone is enjoying their holiday festivities. 
      I'm working on a script that involves copying a string of text from an Excel workbook and searching for it in a particular website's search tool. If a result is found, it will do something. If not, it will do something else.
      So far, it can successfully execute the search -- and then it shows me the results in an array.
      Screenshot of the successful search:

      The search results in an array:

      My main question is: How do I create an If... Then based on what is found in the search results? I need additional tasks to run if Col 1, Row 2 in the array contains the exact string I searched for. (Am I going about this the right way?)
      My next question (I might make a new thread for): How do I make the whole thing loop, as in, copy the next cell in the Excel sheet and do the whole thing over again until there's no more? I understand that a For/Next loop thingy would be used. I just don't know how. Loops are really confusing to me.
      Thank you all for your guidance and have a happy new year!
