如果现在有一个打开的窗口“D:\temp\pp”，如何用VB自动关闭这个窗口。

用FindWindow查找相应标题的句柄，再用SendMessage关闭它。

[东方之珠]

先获取窗口句柄，然后用API函数SendMessage发送WM_Close消息。

[Sandrer]

Const WM_CLOSE = &H10
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Sub Form_Load()
    Dim lngDirWnd As Long
    lngDirWnd = FindWindow(vbNullString, "文件夹标题")
    If lngDirWnd Then Call SendMessage(lngDirWnd, WM_CLOSE, 0, ByVal 0&)
End Sub

好像关不掉。
