估计你和我一样走了弯路.
在MouseWheel代码中有指定frm.
- If lParam.hwnd > 0 Then
- If LISTBOX_Post_Flag = 1 And LISTBOX_Mouse_Flag = 1 Then frm.ListBox1.TopIndex = frm.ListBox1.TopIndex - 1
- If LISTBOX_Post_Flag = 1 And LISTBOX_Mouse_Flag = 2 Then PostMessage mListBoxHwnd, WM_KEYDOWN, VK_UP, 0
- Else
- If LISTBOX_Post_Flag = 1 And LISTBOX_Mouse_Flag = 1 Then frm.ListBox1.TopIndex = frm.ListBox1.TopIndex + 1
- If LISTBOX_Post_Flag = 1 And LISTBOX_Mouse_Flag = 2 Then PostMessage mListBoxHwnd, WM_KEYDOWN, VK_DOWN, 0
- End If

你是不是改动了名字. |
