这段代码是一个 VBA (Visual Basic for Applications) 的子程序,用于遍历指定文件夹下的所有 Excel 文件,并将其转换为 PDF 格式文件。代码中定义了一些对象,如文件系统对象 (objFSO)、Excel 应用对象 (objExcel)、PDF 打印机对象 (objPDFPrinter) 等,用于实现文件的读取、转换和保存等功能。代码中还使用了一个 Label1 控件对象,用于显示正在处理的文件名。在处理每个文件时,程序会将该文件名显示在 Label1 上,并等待 1 秒,以便显示下一个文件名。最后,程序会释放各个对象,并恢复状态栏。

这个代码的作用是将一个文件夹中的所有 Excel 文件转换为 PDF 文件,并将它们保存在指定的文件夹中。该错误通常是由于未正确实例化 "objFile" 对象或该对象的属性 "Name" 不存在或未正确命名而导致的。
请检查以下几点:
1. 检查 "objFile" 对象是否已正确地定义和实例化。您可以在代码中的其他地方查找 "For Each objFile In objFolder.Files" 语句来确认。
2. 确保 "Name" 属性在 "objFile" 对象中存在,且已正确命名。如果名称不正确,您可以使用 "objFile.Name" 来调用正确的名称。
如果以上步骤仍然无法解决问题,请确保您的代码中的变量和对象都已正确定义和实例化,并且您的 VBA 环境中已正确安装 Excel 应用程序。

可以在代码中添加一个用户窗体(UserForm),并在其中添加一个标签(Label),用于显示进度消息。在代码中,可以使用 UserForm.Show 方法显示用户窗体,在 For 循环中,可以更新标签的 Caption 属性,以显示正在处理的文件名。最后,可以使用 UserForm.Hide 方法隐藏用户窗体。以下是修改后的代码示例:
```vb
Sub ConvertExcelToPDF()
' 定义变量
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
Dim objExcel As Object
Dim objWorkbook As Object
Dim objPDFPrinter As Object
Dim strFolderPath As String

Dim i As Long
' 创建用户窗体
Dim frmProgress As UserForm
Set frmProgress = UserForms.Add("frmProgress")
frmProgress.Caption = "转换进度"
frmProgress.Width = 300
frmProgress.Height = 100
frmProgress.Show
' 设置打印机为 Microsoft Print to PDF
Set objPDFPrinter = CreateObject("WScript.Network")
objPDFPrinter.SetDefaultPrinter "Microsoft Print to PDF"
' 设置文件夹路径
strFolderPath = Environ("USERPROFILE") & "\Desktop\1\"
' 创建文件系统对象
Set objFSO = CreateObject("Scripting.FileSystemObject")
' 获取文件夹对象
Set objFolder = objFSO.GetFolder(strFolderPath)
' 遍历文件夹下的所有 Excel 文件

' 打开 Excel 文件

Set objWorkbook = objExcel.Workbooks.Open(objFile.Path)
