拆局专家粤语20:请用vb编写一个找出10000以内的亲密数对的小程序

需要两个函数，一个因子和计算，一个因子和输出。程序窗体放置一个文本框，设置其MultiLine为True。源程序如下：

Option Explicit
Dim I As Long, J As Long, X As Long

Private Sub Form_Load()
Me.Show
For I = 1 To 10000
DoEvents
X = Yzh(I)
If X <= 10000 And I < X Then
If Yzh(X) = I Then
Text1 = Text1 & "(" & I & "," & X & ")" & Chr(13) & Chr(10)
YzhOut (I)
YzhOut (X)
End If
End If
Next
Text1 = Text1 & "计算完成"
End Sub

Private Function Yzh(N As Long) As Long
Yzh = 0
For J = 1 To N / 2
If N Mod J = 0 Then Yzh = Yzh + J
Next
End Function

Private Function YzhOut(N As Long) As Long
Dim Yzh As Long
Text1 = Text1 & N & "=1"
Yzh = 1
For J = 2 To N / 2
If N Mod J = 0 Then
Text1 = Text1 & "+" & J
Yzh = Yzh + J
End If
Next
Text1 = Text1 & "=" & Yzh & Chr(13) & Chr(10)
End Function

程序计算结果，有5组亲密数对，程序输出是：
(220,284)
220=1+2+4+5+10+11+20+22+44+55+110=284
284=1+2+4+71+142=220
(1184,1210)
1184=1+2+4+8+16+32+37+74+148+296+592=1210
1210=1+2+5+10+11+22+55+110+121+242+605=1184
(2620,2924)
2620=1+2+4+5+10+20+131+262+524+655+1310=2924
2924=1+2+4+17+34+43+68+86+172+731+1462=2620
(5020,5564)
5020=1+2+4+5+10+20+251+502+1004+1255+2510=5564
5564=1+2+4+13+26+52+107+214+428+1391+2782=5020
(6232,6368)
6232=1+2+4+8+19+38+41+76+82+152+164+328+779+1558+3116=6368
6368=1+2+4+8+16+32+199+398+796+1592+3184=6232
计算完成

呵呵，用枚举做咯
对每个数都检查一遍看是否符合要求

不过要求一个数的因子和，这个函数我还真的不会
