vb-让listbox右击后先选中

有时我们需要在listbox的某个项目上右击然后弹出菜单来操作指定项，可是右击某一条时它并没有呈现选中状态，只有左键单击才可以，这显然不符合我们要求的，不过我们用个api函数稍稍处理下即可，很方便实用。

Option Explicit Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long,ByVal dx As Long,ByVal dy As Long,ByVal cButtons As Long,ByVal dwExtraInfo As Long) Private Const MOUSEEVENTF_LEFTDOWN = &H2 ' left button down Private Const MOUSEEVENTF_LEFTUP = &H4 ' left button up Private Sub Form_Load() Dim i% For i = 1 To 5 List1.AddItem i Next End Sub Private Sub List1_MouseDown(Button As Integer,Shift As Integer,X As Single,Y As Single) If Button = 2 Then mouse_event MOUSEEVENTF_LEFTDOWN,0 mouse_event MOUSEEVENTF_LEFTUP,0 End If End Sub
