[RESOLVED] ObjectDisposedException Error

[nikel]

Hello, I'm getting this error:

An unhandled exception of type 'System.' occurred in System.Data.SQLite.dll

cannot access a disposed object

... indicating the line:

sqliteDataAdapter = new SQLiteDataAdapter("SELECT * FROM tbl_programs;", m_dbConnection);

Here's my code:

private void addNew_tsmi_Click(object sender, EventArgs e)
{
    info_lbl.Text = "yeni program ekleniyor";
 
    List<string> list = new List<string>();
    int result;
 
    using (InsertData insertData = new InsertData())
    {
        insertData.ShowDialog();
        list = insertData.GetValues();
    }
 
    using (SQLiteConnection connection = m_dbConnection)
    {
        using (SQLiteCommand command = new SQLiteCommand(
            "INSERT INTO tbl_programs " +
            "(int_isSelected, txt_programName, int_is86, int_is64, txt_preCommand, " +
            "txt_preSwitch, txt_executable, txt_switches, int_timeout, txt_md5, txt_version, " +
            "txt_description, txt_category, dt_insertDate) " +
            "VALUES(" +
            ":isSelected, :programName, :is86, :is64, :preCommand, :preSwitch, :executable, " +
            ":switches, :timeout, :md5, :version, :description, :category, :insertDate);",
             connection))
        {
            command.Parameters.AddWithValue("isSelected", 0);
            command.Parameters.AddWithValue("programName", list[0]);
            ...
 
            connection.Open();
 
            command.ExecuteNonQuery();
        }
    }
 
    InitialiseDataAccessObjects();
    GetData();
 
    info_lbl.Text = "hazır";
}
 
private void InitialiseDataAccessObjects()
{
    sqliteDataAdapter = new SQLiteDataAdapter("SELECT * FROM tbl_programs;", m_dbConnection);
    sqliteCommandBuilder = new SQLiteCommandBuilder(sqliteDataAdapter);
 
    sqliteDataAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
}
 
private void GetData()
{
    // Retrieve the data.
    sqliteDataAdapter.Fill(dataTable);
 
    // The table can be used here to display and edit the data.
    // That will most likely involve data-binding but that is not a data access issue.
}

Can anyone help me?
