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 ExtractIcon Lib "shell32.dll" Alias "ExtractIconA"(ByVal hInst As Long, ByVal lpszExeFileName As String, ByVal nIconIndex AsLong) As LongPrivate Declare Function SendMessage Lib "use32" Alias "SendMessageA"(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Integer, ByVal lParamAs Long) As LongPrivate Declare Function FindWindow Lib "use32" Alias "FindWindowA"(ByVal lpClassName As String, ByVal lpWindowName As String) As LongPrivate Sub UserForm_Initialize() Dim hWndForm&, hIcon& hWndForm=FindWindow("ThunderDFrame", Me.Caption) hIcon=ExtractIcon(0, ThisWorkbook.Path & "\winamp.ico", 0) SendMessage hWndForm, &H80, False, hIconEnd Sub
