SecurityException was Unhandled

[jtnpham]

This is code I created to add a record where the user inputs the new
text in textboxes:

Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnAdd.Click
City = txtCity.Text
Country = txtCountry.Text
p2005 = txt2005.Text
p2015 = txt2015.Text

Dim dt As New DataTable()
Dim connStr As String = "Provider = Microsoft.Jet.oledb.4.0;"
& "Data Source=F:\Pham\megacities.mdb"
Dim sqlStr As String = "INSERT INTO Cities VALUES('city',
'country', 'p2005', 'p2015')"
Dim dataadapter As New OleDb.OleDbDataAdapter(sqlStr, connStr)
dataadapter.Fill(dt)
dataadapter.Dispose()

End Sub

When I run the program it stops at dataadapter.Fill(dt) and gives me
the error message: Security Exception was Unhandled.

Can anyone help me?

Thanks!

Are you running it from a network, or accessing a network resource to load
the database?

If so you may need to change settings on the computer to "Trust" the
assembly

where do i go to change it to "trusted"?

 

[Michael M.]

In the control panel -> microsoft.net configuration wizards icon "Runtime
security policy"

I can not explain the exact steps as I find this console quite complex
myself, but this is where you get it done.

I tend not to run .NET applications from a network share for this reason.
