Build a Simple VCL Application for Xero WorkflowMax Data

How to build a simple VCL Application to view Xero WorkflowMax data in RAD Studio using the CData FireDAC Components for Xero WorkflowMax.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for Xero WorkflowMax, you gain access to live Xero WorkflowMax data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Xero WorkflowMax data. This article will walk through connecting to Xero WorkflowMax and creating a simple VCL application with the Form Designer.

Creating a VCL Application for Xero WorkflowMax Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to Xero WorkflowMax from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysXeroWorkflowMaxDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.XeroWorkflowMax" in the DriverId menu and configure the connection properties.

    To connect to the WorkflowMax API, obtain an APIKey and AccountKey from Xero. This can only be done by contacting Xero support (https://www.workflowmax.com/contact-us).

    After obtaining an API Key and Account Key, set the values in the APIKey and AccountKey connection properties. Once these are set, you are ready to connect.

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
