excel VBA 窗体之拖动边界改变大小窗体 实现代码

我们已经有了一系列怎样增强 VBA 窗体的文章，VBA 的窗体和一般正常的窗体区别很大，比如就不可以通过用鼠标拖动窗体的边框，我们今天就讲讲怎样给 VBA 窗体添加这个功能。

操作如下：
?在Excel 的VBE窗口中插入一个用户窗体，将其命名为 frmNotEnabledCloseIcon。然后再添加一个模块。在窗体和模块中添加后面所列代码。
?在工作薄中的工作表中添加一窗体按钮控件，指定其设置宏 ShowNotEnabledCloseIconForm, 其供示范之用.

 

具体代码：

 

"frmThickFram" 窗体代码

'以下定义常数和变量
Private Const GWL_STYLE = (-16) '窗口样式
Private Const WS_THICKFRAME = &H40000 '可更改大小
'---关闭按钮---
Private Sub btnClose_Click()
Unload Me
End Sub
'---窗体初始化---
Private Sub UserForm_Initialize()
On Error Resume Next
'查找窗体句柄
hWndForm = FindWindow("ThunderDFrame", Me.Caption)
'取得窗体样式
FIstype = GetWindowLong(hWndForm, GWL_STYLE)
'窗体样式：原样式和可拖动边框改变大小
FIstype = FIstype Or WS_THICKFRAME
'重设窗体样式
SetWindowLong hWndForm, GWL_STYLE, FIstype
'重绘窗体标题栏
DrawMenuBar hWndForm
End Sub

"mdThickfram" 模块代码

Option Explicit '
此过程为工作表内按钮调用
Sub ShowThickFramForm()
frmThickFram.Show
End Sub
