[函数]获取AutoCAD命令行窗口句柄的函数

Option Explicit
'相关 API 函数声明
Public Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, _
      ByVal lpString As String, ByVal cch As Long) As Long '取得指定窗口的标题
Public Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, ByVal wCmd As Long) As Long '取得窗口句柄
Public Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long '获取父窗口句柄

Const GW_CHILD = 5
Const GW_HWNDNEXT = 2
Const WM_GETTEXT = &HD
Const WM_GETTEXTLENGTH = &HE

'获取命令行窗口句柄的示例
Sub MC_GetCommandLineSample()
    Debug.Print GetCommandLineWindows(GetAcadHwnd)
End Sub

'获取AutoCAD主窗口句柄
Public Function GetAcadHwnd() As Long
    GetAcadHwnd = GetParent(GetParent(ThisDrawing.hwnd))
End Function


'遍查子窗口,判断窗口是否为命令行窗口,并返回命令行窗口句柄
Public Function GetCommandLineWindows(Window_Hwnd As Long) As Long
    Dim Buf As String
    Dim BufLen As Long
    Dim Child_hwnd As Long
    Dim Children() As Long
    Dim Num_Children As Integer
    Dim i As Integer
    Dim TitleText As String * 1024
    Dim TitleLeng As Long
    Dim Title As String
    Dim CHwnd As Long
   
    TitleLeng = GetWindowText(Window_Hwnd, TitleText, Len(TitleText))
    Title = Left$(TitleText, TitleLeng)
    If Left(Title, 3) = "命令行" Or Left(Title, 12) = "Command Line" Then
      GetCommandLineWindows = Window_Hwnd
      Exit Function
    End If
   
   
    Num_Children = 0
    Child_hwnd = GetWindow(Window_Hwnd, GW_CHILD) '取得第 1 个子窗口的句柄
    Do While Child_hwnd <> 0 '如果有子窗口
      Num_Children = Num_Children + 1
      ReDim Preserve Children(1 To Num_Children)
      Children(Num_Children) = Child_hwnd
      Child_hwnd = GetWindow(Child_hwnd, GW_HWNDNEXT) '取得下一个兄弟窗口的句柄
    Loop
   
    For i = 1 To Num_Children
      CHwnd = GetCommandLineWindows(Children(i))
      If CHwnd <> 0 Then GetCommandLineWindows = CHwnd
    Next i
   
End Function

该函数进行一些改造,还可以取得AutoCAD窗口中任何一个控件的句柄。

获得后可用来做什么?

这是一个好方法啊,只是我想获取命令行中所输入的内容应该怎么做呢?请教一下老大。
