我想隐藏任务栏中的 Excel 按钮并为我的用户窗体显示一个单独的按钮,这样它就好像一个应用程序本身。我知道这已经涵盖了很多,但我遇到了一个特定问题:我的代码在我单步执行时工作正常,但如果我让它正常运行就不行。这是我放在 Userform1 的类模块中的代码:
Option Explicit
Private Declare Function GetWindowLong _
Lib "user32" _
Alias "GetWindowLongA" ( _
ByVal hWnd As Long, _
ByVal nIndex As Long) _
As Long
Private Declare Function SetWindowLong _
Lib "user32" _
Alias "SetWindowLongA" ( _
ByVal hWnd As Long, _
ByVal nIndex As Long, _
ByVal dwNewLong As Long) _
As Long
Private Declare Function DrawMenuBar _
Lib "user32" ( _
ByVal hWnd As Long) _
As Long
Private Declare Function FindWindowA _
Lib "user32" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String) _
As Long
Private Const GWL_EXSTYLE = (-20)
Private Const GWL_STYLE As Long = (-16)
Private Const WS_EX_APPWINDOW = &H40000
Private Const WS_SYSMENU As Long = &H80000
Private Const WS_MINIMIZEBOX As Long = &H20000
Private Const WS_MAXIMIZEBOX As Long = &H10000
Private Sub UserForm_Activate()
Dim lFrmWndHdl As Long
Dim lStyle As Long
lFrmWndHdl = FindWindowA(vbNullString, Me.Caption)
lStyle = GetWindowLong(lFrmWndHdl, GWL_STYLE)
lStyle = lStyle Or WS_SYSMENU
lStyle = lStyle Or WS_MINIMIZEBOX
lStyle = lStyle Or WS_MAXIMIZEBOX
SetWindowLong lFrmWndHdl, GWL_STYLE, (lStyle)
lStyle = GetWindowLong(lFrmWndHdl, GWL_EXSTYLE)
lStyle = lStyle Or WS_EX_APPWINDOW
SetWindowLong lFrmWndHdl, GWL_EXSTYLE, lStyle
DrawMenuBar lFrmWndHdl
AppActivate ("Microsoft Excel")
ThisWorkbook.Application.Visible = False
End Sub
单步执行代码,当我进入倒数第二行 AppActivate 时,任务栏中会出现一个单独的按钮,最后一行隐藏了任务栏中 Excel 工作簿的原始按钮。然后我只剩下一个用户表单,可以像任何普通应用程序一样最大化或最小化到任务栏。问题是如果我通过代码加载用户表单,则用户表单的单独按钮不会出现在任务栏中,因此任务栏中不会显示 Excel 按钮。
