Excel vba - resize as date format - vba

Question

I have a line in code:
.Range("D2").Resize(UBound(vef, 1), 1) = vef
Where vef is an array with data. Can I edit this line so it pastes vef in Date format dd.mm.yyyy hh:mm:ss

Answer 1

That should be easy enough. All you need to do is work with the same range and change the numberformat of the cells. Please note: the value being pasted is unchanged (and the values in your array should be dates). Excel applies a formatting so that what is displayed is changed, but without losing the underlying information.
If your array is full of strings, you will want to look at converting them to Dates beforehand. Excel may do this implicitly (e.g it may automatically format them, despite the original values being dates), but explicit conversion is preferred.
For your code, use this:
With .Range("D2").Resize(UBound(vef, 1), 1)
.Value = vef
.Numberformat = "dd.mm.yyyy hh:mm:ss"
End With
Finally, I would just point out that your Ubound(vef, 1) will only work if your array is 1 based. If it is 0 based, your resized range will be off by 1. The formula you can use to find the length of a dimension in an array is:
Length = (Ubound(Array, DimensionNumber) - LBound(Array, DimensionNumber)) + 1
So in your case:
Length = (Ubound(vef, 1) - LBound(vef, 1)) + 1
Good luck!
