怎样使用VBA将窗体置于上层？

1、首先在开发工具中打开VBA编辑器

2、在单元格区域当中输入一些内容作为例子

3、在VBA编辑器中插入模块

4、在模块当中输入如下代码，然后运行

Private Declare Function FindWindow Lib "use32.dll" Alias "FindWindowA"

(ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SetWindowPos Lib "use32" (ByVal hWnd As Long,
ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx
As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Const HWND_TOPMOST=-1
Private Const SWP_NOSIZE=&H1
Private Sub UserForm_Initialize()
    Dim hWnd As Long
    hWnd=FindWindow(vbNullString, Me.Caption)
    SetWindowPos hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE
End Sub

5、用快捷键F5运行窗体，窗体置于所有应用程序界面上层。打开Word程序，可以看到虽然焦点在Word，但Excel窗体仍处于Word上层，如图
