Connect to Tally Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Tally in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Tally to retrieve data.

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

   Url='http://localhost:9000'

   Set the following connection properties to connect to Tally Instance:

   • Url: Set this to the URL for your Tally instance. For example: http://localhost:9000.
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=Name}" Header="Name" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Tally 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.Tally.TallyConnection conn 
conn = create System.Data.CData.Tally.TallyConnection(connectionString)

System.Data.CData.Tally.TallyCommand comm 
comm = create System.Data.CData.Tally.TallyCommand(command, conn)

System.Data.DataTable table
table = create System.Data.DataTable

System.Data.CData.Tally.TallyDataAdapter dataAdapter
dataAdapter = create System.Data.CData.Tally.TallyDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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