Raptor Database Exception Error?

See more:

VB

Ok I have tried the code and at first it seems error free until I try to debug it. Maybe you can see where I have went wrong?

Imports RaptorDB 

Public Class Form1 
Dim rap As RaptorDB.RaptorDB = RaptorDB.RaptorDB.Open("storage", 255, False, INDEXTYPE.HASH) 

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 rap.Set("A1", "123456789") ' to set like a dictionary 
 Dim val As String = "" 
If rap.Get("A1", val) Then 
TextBox1.Text = val 
End If 
End Sub 
End Class

The error message I get is:

System.InvalidOperationException was unhandled Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Path cannot be the empty string or all whitespace.

See Exception.InnerException for details. 

The error is: Path cannot be the empty string or all whitespace.

Does anyone have a solution to this problem?
