How to build a simple VCL Application to view Wave Financial data in RAD Studio using the CData ODBC Driver for Wave Financial.
Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Wave Financial, you gain access to live Wave Financial data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Wave Financial data. This article will walk through connecting to Wave Financial and creating a simple VCL application with the Form Designer.
Create a Connection to Wave Financial Data
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Connect using the API Token
You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:
- Log in to your Wave account and navigate to "Manage Applications" in the left pane.
- Select the application that you would like to create a token for. You may need to create an application first.
- Click the "Create token" button to generate an APIToken.
Connect using OAuth
If you wish, you can connect using the embedded OAuth credentials. See the Help documentation for more information.
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Wave Financial data.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Wave Financial.
Create VCL Applications with Connectivity to Wave Financial Data
Follow the procedure below to start executing queries to Wave Financial data from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Wave Financial data.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
Drop a TFDQuery component onto the form and set the properties below:
- Connection: Set this property to the TFDConnection component, if this component is not already specified.
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Id, DueDate FROM Invoices WHERE Status = 'SENT'
- Active: Set this property to true.
Drop a TDataSource component onto the form and set the following property:
- DataSet: In the menu for this property, select the name of the TFDQuery component.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- 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.
