Getting Error : Invalid PInvoke metadata format. while accessing mysql through Bytefx .net native provider

[Miku]

Hi Guies,

I am new to vb.net.
In my project I am using vb.net & MySql 4.0.17 as a backend. For
database connectivity i have downloaded ByteFX - Mysql .net native
provider.

I have written the following code to connect with database:

Imports ByteFX.Data.MyS qlClient
Imports System.Data
Public Class Form1
Inherits System.Windows. Forms.Form

#Region " Windows Form Designer generated code "

Public Sub New()
MyBase.New()

'This call is required by the Windows Form Designer.
InitializeCompo nent()

'Add any initialization after the InitializeCompo nent() call

End Sub

'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As
Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Disp ose()
End If
End If
MyBase.Dispose( disposing)
End Sub

'Required by the Windows Form Designer
Private components As System.Componen tModel.IContain er

'NOTE: The following procedure is required by the Windows Form
Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
Friend WithEvents Button1 As System.Windows. Forms.Button
<System.Diagnos tics.DebuggerSt epThrough()> Private Sub
InitializeCompo nent()
Me.Button1 = New System.Windows. Forms.Button()
Me.SuspendLayou t()
'
'Button1
'
Me.Button1.Loca tion = New System.Drawing. Point(64, 128)
Me.Button1.Name = "Button1"
Me.Button1.TabI ndex = 0
Me.Button1.Text = "Button1"
'
'Form1
'
Me.AutoScaleBas eSize = New System.Drawing. Size(5, 13)
Me.ClientSize = New System.Drawing. Size(292, 273)
Me.Controls.Add Range(New System.Windows. Forms.Control()
{Me.Button1})
Me.Name = "Form1"
Me.Text = "Form1"
Me.ResumeLayout (False)

End Sub

#End Region

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e
As System.EventArg s) Handles Button1.Click
Dim strConString As String
strConString = "Database=sona; server=localhos t;uid=;pwd=;"
Dim con As New MySqlConnection (strConString)
con.Open()
MsgBox("Success ful")
End Sub
End Class

When i run my application i get error at con.open() line as below:

An unhandled exception of type 'System.TypeLoa dException' occurred in
system.dll

Additional information: Invalid PInvoke metadata format.

Pl. Help me out.

Hi Miku,

Ask this also in the newsgroup

microsoft.publi c.dotnet.langua ges.vb

There is someone active in that newsgroup who loves PInvoke.
