Empty Dataset

How can I check whether the retreived dataset is empty? I've tried to do it with the code below but it generates an error

Regards,

John

DsProfile1.Clear()
OleDbDataAdapter1.Fill(DsProfile1)

Dim iCnt As Integer
iCnt = Me.BindingContext(DsProfile1, "profileid").Count

if icnt = 0 etc etc

Not sure whether anyone is interested! The answer is below:

DsProfile1.Clear()
OleDbDataAdapter1.Fill(DsProfile1, "Combined")

Dim iCnt As Integer

iCnt = DsProfile1.Tables("Combined").Rows.Count
