Connect to AvaTax Data from PowerBuilder

This article demonstrates how to access AvaTax data from PowerBuilder using the CData ADO.NET Provider for AvaTax.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for AvaTax in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for AvaTax to perform reads and writes.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    User=MyUser;Password=MyPassword;

    The primary method for performing basic authentication is to provide your login credentials, as follows:

    • User: Set this to your username.
    • Password: Set this to your password.

    Optionally, if you are making use of a sandbox environment, set the following:

    • UseSandbox: Set this to true if you are authenticating with a sandbox account.

    Authenticating Using Account Number and License Key

    Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

    • AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
    • LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account adminstrator and navigating to Settings -> Reset License Key.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for AvaTax assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.AvalaraAvatax.AvalaraAvataxConnection conn conn = create System.Data.CData.AvalaraAvatax.AvalaraAvataxConnection(connectionString) System.Data.CData.AvalaraAvatax.AvalaraAvataxCommand comm comm = create System.Data.CData.AvalaraAvatax.AvalaraAvataxCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.AvalaraAvatax.AvalaraAvataxDataAdapter dataAdapter dataAdapter = create System.Data.CData.AvalaraAvatax.AvalaraAvataxDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
