DiminstanceAsDataConnectionFile

The UDC files that are available on the server farm are listed on the Manage Data Connection Files page of the Central Administration site. A version 2 UDC file with the *.udcx file extension is designed for use by browser-enabled form templates that render in the browser or open in the InfoPath editor. Form templates that are not browser-enabled can also use UDC connection files.

In the following example, the DataConnectionFileCollection collection is used to loop through every UDC file on the server farm and write its display name to the console. Then the total number of UDC files on the server is written to the console.

    Dim LocalFormsService As FormsService
    Dim LocalFarm As SPFarm
    Dim UdcCollection As DataConnectionFileCollection
    Dim UdcConnection As DataConnectionFile
    Dim CountUdcFiles As Integer = 0
    Try
        LocalFarm = SPFarm.Local
        LocalFormsService = LocalFarm.Services.GetValue(Of FormsService)(FormsService.ServiceName)
        UdcCollection = LocalFormsService.DataConnectionFiles
        For Each UdcConnection In UdcCollection
            CountUdcFiles = CountUdcFiles + 1
            Console.WriteLine("UDC file # " + CountUdcFiles.ToString() + ": " + UdcConnection.DisplayName.ToString())
        Next
        Console.WriteLine("Total UDC files on server: " + CountUdcFiles.ToString())
        Console.Write("Press Enter to Continue")
        Console.ReadLine()
    Catch ex As Exception
        Console.WriteLine("Error: " + ex.Message)
        Console.Write("Press Enter to Continue")
        Console.ReadLine()
    End Try
