使用OleDb Connection搜索用户，但在向OLEDB COMMAND添加参数值时出现错误

Question

我正在尝试添加参数，但我收到的错误如下：

    glCommand.ExecuteReader Run-time exception thrown : System.InvalidOperationException - 

  

'adsdsoobject'提供程序不支持ICommandWithParameters接口   当前提供程序不支持命令参数。

我的代码：

Dim strSql As String = "SELECT SAMACCOUNTNAME, DISPLAYNAME, DEPARTMENT FROM 'LDAP://xxx.com.my' WHERE ObjectClass='user' AND EXTENSIONATTRIBUTE8 = 'PM' AND DISPLAYNAME = ? ORDER BY DISPLAYNAME "

 glConnection = New OleDbConnection("Provider=adsdsoobject;User Id=xxx.com.my\UAMTEAM;Password=" + ClsGlobal.Decrypt(strpwd) + ";")


        glCommand = New OleDbCommand(strSql, glConnection)
        ' Add the input parameter and set its properties.
        Dim parameter As New OleDbParameter()
        parameter.ParameterName = "@param2"
        parameter.OleDbType = OleDbType.VarChar
        parameter.Direction = ParameterDirection.Input
        parameter.Value = param1

        ' Add the parameter to the Parameters collection.
        glCommand.Parameters.Add(parameter)

        glConnection.Open()

        glReader = glCommand.ExecuteReader
