convert date to date serial
提问by michael.t
I'm trying to convert a date (date type) into a long. This long should be something like the number of days since the 1 January 1900. How to get this in VBA ? In excel I'm getting this automatically when i concatenate a date with a string.
我正在尝试将日期(日期类型)转换为 long。这个长应该是自 1900 年 1 月 1 日以来的天数。如何在 VBA 中得到这个?在 excel 中,当我将日期与字符串连接时,我会自动获取此信息。

Function dateToLong(ByVal d As Date) As Long
dateToLong = CLng(d)
End Function
If you need to capture the time in the long use this:
如果您需要长时间捕获时间,请使用以下命令:
Function Dt2Lng(aDate As Date) As Long
'-- acept datetime range from MinDate to
'-- (MinDate + 49710 days + 6:28:15) ~ 136 years
Dt2Lng = CLng((aDate - MinDate) * 86400 - 2 ^ 31)
End Function

Say if you have "1/1/2016" in A1, you could use Range("A1").Value2 to get the date serial number.
假设您在 A1 中有“1/1/2016”,您可以使用 Range("A1").Value2 来获取日期序列号。
