I need $idDate from code 1 to update even after a manual change is made by the user. Now, every time when i change the date it does not apply in code 2 and it always add 4 hours. 

I would appriociate any help

 

Code 1:

If GUICtrlRead($idComboBox) = "A" Then
                        GUICtrlDelete($idProblemLabel)
                        $idProblemLabel = GUICtrlCreateLabel("2 hodiny" & @CRLF & "vysoká teplota na více jak 25% nábytku" & @CRLF & "centrální výpadek chlazení" & @CRLF & "výpaden PC" & @CRLF & "nedostatek chladiva jednotky" & @CRLF & "dva a více kompresory v alarmu", 10, 70)

                        $idDate = GUICtrlCreateDate("", 10, 210, 160, 26, $DTS_SHORTDATEFORMAT)
                        $sStyle = "yyyy/MM/dd HH:mm:ss"
                        GUICtrlSendMsg($idDate, $DTM_SETFORMATW, 0, $sStyle)
                        $newdate = _DateAdd('h', 2, _NowCalc())
                        GUICtrlSetData($idDate, $newdate)
                        Local $sStyle = "dd.MM.yyyy HH:mm"
                        GUICtrlSendMsg($idDate, $DTM_SETFORMATW, 0, $sStyle)

EndIf


Code 2:
If Not StringInStr(GUICtrlRead($idInput1), "_") Then
                    ClipPut(GUICtrlRead($idComboBox) & "_" & GUICtrlRead($idDate) & "_" & GUICtrlRead($idInput1))
                    MsgBox($MB_SYSTEMMODAL, "Title", "Vloženo do clip boardu. Okno se zavre za 10sec" & @CRLF & GUICtrlRead($idComboBox) & "_" & GUICtrlRead($idDate) & "_" & GUICtrlRead($idInput1), 10)
                    GUICtrlSetData($idInput1, "")
