I have this function where i search through my database for items that were made on a specific date. The line "CType(dvClubs.Item(teller).Item(veld).ToShortDate String" gives me the error : option strict on disallows late binding. I have read some posts here about late binding but I just can't figure it out :s This code worked with option strict off, but i just heard that we had to write our program with option strict on :/
I hope you guys can help me
Public Function ZoekOntstaan(ByVal search As Date, ByVal veld As String) As Integer
For teller As Integer = 0 To dvClubs.Count - 1
If CType(dvClubs.Item(teller).Item(veld).ToShortDateS tring, String) = search Then
Return teller
End If
Next
Return -1
End Function

You can remove the 'CType' because 'ToShortDateString' already returns a
string. Maybe you need to cast 'dvClubs.Item(teller)' and
'<...>.Item(veld)'.

Try:
You need to convert dvClubs.Item(teller).Item(veld) to a DateTime before
using the ToShortDateString as it's data type is unknown.
For teller As Integer = 0 To dvClubs.Count - 1
Dim dt As DateTime = CType(dvClubs.Item(teller).Item(veld),
DateTime)
If dt.ToShortDateString = search Then
Return
End If
Next
Hope this help.

Well, now I've got an error on the dt.ToShortDateString => option strict on disallows implicit conversions from string to date
thanks for the help already

Normally this should be as far as I can see enough,
If DirectCast(dvClubs(teller)(veld),DateTime).Date = search.Date Then
Cast in the dataview the object at row(teller) and in that the item(veld) as
datetime and use in that the date part to compare with the date part from
the datetimefield Search
I hope this helps?

Well, I just changed my table so that i don't have a full date like 15/02/1900 but i just made it an integer with the year in, so just 1900, a lot easier like this :)
thanks for all your help

In this case it would be better to compare the dates directly:
