I want to create a date exactly 90 earlier. Add days with a negative value gives me this error:

Conversion from string "02/09/2011" to type 'Long' is not valid.

VB

New Date(Now.AddDays(-90).ToShortDateString)

Solution 3

If you are assigning String Value as a Date then this Error occurs.
There is no constructor for Date which take Date in String format as it is.Try this one :

VB

Dim _Date As Date = New Date("2011", 12, "1")
MessageBox.Show(_Date.Month - 3)

I hope it will help you. :)

What's wrong with:

VB

Dim dt As Date = Now.AddDays(-90)

?
