List1.RemoveItem List1.ListIndex List1.listcount VB代码意思List1.RemoveItem List1.ListIndex List1.List (List1.ListCount - 1)是什么意思 vf中 ThisForm.List1.list(ThisForm.List1.listindex); list1.listindex与list1.index有什么区别 vb编程:单词分解怎么编?Private Sub Command1_Click() Dim s As String,a() As String,i As Integer s = Text1.Text Call aword(s,a) List1.AddItem p End Sub Private Sub Command2_Click() Text1.Text = List1.Clear Text1.SetFocus End Sub Private Sub VB:For i = 0 To List1.ListCount - 1,后面的List1.ListCount - list1.listindex(i)和list1.selected（i）什么区别?怎么用? For i = 0 To List1.ListCount - 1 FOR i=1 TO thisform.List1.ListCount是什么意思? vb产生20个随机数放入list1再将其中不同的数放在list2 VB将一组数随机排列到list1,比如1到100 请问VB当中当list1里的数字到list2中后按大小排列的代码该怎么写?如图所示,list1中的数字到list2中后按从小到大排列,然后在list1中加入新数字,左右互换后,两边的数字依然按从小到大排列.Private 请问VFP中下面这个程序该怎么翻译呢?s=f=.T.*** FOUND ***FOR i=1 TO thisform.List1.Count IF thisform.List1.Selected(i) IF f*** FOUND *** s=thisform.List1.list(i) f=.F. ELSE*** FOUND *** s=s+thisform.L 在VB中不停产生随机数,直至有10个质数为止,将所有随机数输入LIST1,将10个质数输入LIST2中.
