Hi @Rex Lau ,

You can use Microsoft.Office.Interop.Visio Namespace.

Check if the following code works for you.

Imports Microsoft.Office.Interop.Visio

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim processor As New VisioProcessor()
        processor.ProcessVisioFiles("C:\YourFolderPath")

    End Sub
    Public Sub ProcessVisioFiles(folderPath As String)
        Dim visioApp As New Application()
        visioApp.Visible = False

        Dim files As String() = IO.Directory.GetFiles(folderPath, "*.vsd*", IO.SearchOption.TopDirectoryOnly)

        For Each filePath As String In files
            Dim doc As Document = visioApp.Documents.Open(filePath)
            Console.WriteLine("File: " & filePath)

            For Each page As Page In doc.Pages
                Console.WriteLine("Page Name: " & page.Name)
                Dim shapesCount As Integer = page.Shapes.Count
                Console.WriteLine("Number of Shapes: " & shapesCount)
            Next

            doc.Close()
        Next

        visioApp.Quit()
    End Sub
End Class

Best Regards.
