ListBox中的字符串超长显示的解决方法
使用ToolTip来解决超长文字的显示问题是不错的方案，下面给出了例子的代码。
Option Explicit
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 Const LB_ITEMFROMPOINT = &H1A9
Private Sub Form_Load()
Dim i As Integer
For i = 0 To 5
List1.AddItem "ListItem字符串超长超长超长超长超长咯 " & i
Next
End Sub
Private Sub List1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim lParam As Long
Dim lResult As Long
lParam = (CInt(Y / Screen.TwipsPerPixelY) * 2 ^ 16) + CInt(X / Screen.TwipsPerPixelX)
lResult = SendMessage(List1.hwnd, LB_ITEMFROMPOINT, 0, ByVal lParam)
If lResult < 0 Or lResult > 32767 Then
List1.ToolTipText = ""
Exit Sub
End If
Dim nIndex As Integer
nIndex = CInt(lResult)
List1.ToolTipText = List1.List(nIndex)
End Sub
在 Win2000 + VB6 中调试通过
