从混合列表框加载 axacropdf（pdf 组件）上的文件

Question

我正在获取文件夹名称，并在同一目录中获取 pdf 文件，并使用以下代码将两者列在同一列表框中：

        Private Sub frmBooks_Load(sender As Object, e As EventArgs) Handles MyBase.Load
For Each folder As String In System.IO.Directory.GetDirectories(Application.StartupPath & "\Books")
        ListBox1.Items.Add(Path.GetFileName(folder))
    Next
    For Each file As String In System.IO.Directory.GetFiles(Application.StartupPath & "\Books\", "*.pdf")
        ListBox1.Items.Add(Path.GetFileNameWithoutExtension(file))
    Next

两者在同一个列表框中混合并排序1 然后我添加 axacropdf（PDF 组件）来读取 pdf 文件。我如何 open/get 从列表框的选定项目到在 axacropdf 打开的路径？

(axacropdf.src =)

Answer 1

此代码检查文件是否以 .pdf 格式存在

Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
    If File.Exists(Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf") = True Then
        AxAcroPDF1.src = (Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf")
end if
   end sub
