输入一系列字符串，按递减次序排列。

'Command1,Text1,Picture1各1个

Dim n%, s(100) As String

Private Sub Form_Load()

Command1.Caption = "排序"

Picture1.AutoRedraw = True

Text1 = ""

End Sub

Private Sub text1_keypress(keyascii As Integer)

If n >= 100 Then Exit Sub

If keyascii = 13 Then

s(n) = Text1

Text1 = ""

n = n + 1

End If

End Sub

Private Sub Command1_Click()

Picture1.Cls

n = n - 1 '实际个数

For i = 0 To n - 1

For j = i + 1 To n

If s(j) <> "" Then

If s(i) < s(j) Then

temp = s(i): s(i) = s(j): s(j) = temp

End If

End If

Next j

Next i

For i = 0 To n

Picture1.Print s(i); "|";

If (i + 1) Mod 5 = 0 Then Picture1.Print

Next i

n = n + 1 '准备下次输入

End Sub

以下是完整版的内容(包括界面)。
用法如下：先把下面代码保存为Form1.frm文件，然后双击打开此文件，运行，输入数据，最后点击排序按钮即可。

End If
End If
End Sub

Private Sub Command1_Click()
Dim i, j, temp

For j = i + 1 To n - 1
If s(i) < s(j) Then

End If
Next j
Next i
Picture1.Print "按递减次序的排列如下："
For i = 0 To n
Picture1.Print s(i)
DoEvents
Next
End Sub

前面的代码不变，以下是排序代码：
for i=0 to 99
for j=i+1 to 100
if s(j)<>"" then
if s(i)temp=s(i):s(i)=s(j):s(j)=temp
end if
end if
next j
next i
for i=0 to 100
picture1.print s(i)
next i
