[Mono-dev] facing problems while running VB.Net application on Mono in Linux

[Singh, Narendra Kumar]

Hi ,

Actually we have developed an application which connects to Oracle 10G
and accesses some tables.

The application is working fine when it is build with Visual; Studio.Net
2003

But the sample application is not working on Linux in Mono

The error is as follows

Unhandled Exception: System.DllNotFoundException: oci 
in <0x00053> (wrapper managed-to-native) OciNativeCalls:OCIEnvCreate
(intptr&,System.Data.OracleClient.Oci.OciEnvironmentMode,intptr,intptr,i
ntptr,intptr,int,intptr)
in <0x00020> System.Data.OracleClient.Oci.OciCalls:OCIEnvCreate
(intptr&,System.Data.OracleClient.Oci.OciEnvironmentMode,intptr,intptr,i
ntptr,intptr,int,intptr)

in <0x0004f> (wrapper remoting-invoke-with-check)
System.Data.OracleClient.OracleConnection:Open () 
in <0x0006a> Test:Main (string[]) 
 
 
and the code is as follows:
 

Imports System.Data

Imports System.Data.OracleClient

 

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.

        InitializeComponent()

 

        'Add any initialization after the InitializeComponent() 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.Dispose()

            End If

        End If

        MyBase.Dispose(disposing)

    End Sub

 

    'Required by the Windows Form Designer

    Private components As System.ComponentModel.IContainer

 

    '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 ListBox1 As System.Windows.Forms.ListBox

    <System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()

        Me.ListBox1 = New System.Windows.Forms.ListBox

        Me.SuspendLayout()

        '

        'ListBox1

        '

        Me.ListBox1.Location = New System.Drawing.Point(72, 48)

        Me.ListBox1.Name = "ListBox1"

        Me.ListBox1.Size = New System.Drawing.Size(104, 95)

        Me.ListBox1.TabIndex = 0

        '

        'Form1

        '

        Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)

        Me.ClientSize = New System.Drawing.Size(292, 266)

        Me.Controls.Add(Me.ListBox1)

        Me.Name = "Form1"

        Me.Text = "Form1"

        Me.ResumeLayout(False)

 

    End Sub

 

#End Region

 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

        Dim con As New OracleConnection("Password=userdummy;User
ID=dummyuser;Data Source=dot")

        con.Open()

        Dim da As New OracleDataAdapter("select USERID from dbuser",
con)

        Dim ds As New DataSet

        da.Fill(ds, "dbuser")

        ListBox1.DataSource = ds.Tables("dbuser")

        ListBox1.DisplayMember = "USERID"

    End Sub

 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)

 

    End Sub

End Class

 
 
Please suggest some ways to solve this problem
