这样读写比较好:读取: Dim TempFile As Long Dim LoadBytes() As ByteTempFile=FreeFile Open 文件名 For Binary As #TempFile Redim LoadBytes(1 To Lof(TempFile)) As Byte Get #TempFile,,LoadBytes Close TempFileText1.Text=StrConv(LoadBytes,vbUniCode)写入: Dim TempFile As Long Dim SaveBytes() As ByteSaveBytes=StrConv(Text1.Text,vbFromUniCode)TempFile=FreeFile Open 文件名 For Binary As #TempFile Put #TempFile,,SaveBytes Close TempFile
还有一个办法。 你可以这样做。 用left取出text的每一位,然后加其你想得到最后数值的ascii码 然后再转回字符就ok 了 这有一个例子 '根据用户输入生成不定序列号,其值为S s2 = "" S = "" s1 = "" If txtuse.Text = "" Then MsgBox "请输入用户名!", , "提示" Else s2 = txtuse.Text For I = 1 To Len(txtuse.Text) A = Left(txtuse.Text, I) b = Right(A, 1) m = Asc(b) - I 100: If m >= 65 And m <= 90 Then S = S + Chr(m) Else If m < 65 Then m = m + I Else m = m - I End If GoTo 100 End If Next s1 = S '生成固定长度 If Len(S) < 10 Then For j = 1 To 10 - Len(s1) d = Left(s1, I) e = Right(d, 1) k = Asc(e) - j 104: If k >= 65 And k <= 90 Then S = S + Chr(k) Else If k < 65 Then k = k + j Else

Dim strLine As String
Open "SourceFileName" For Input As #1
Do While Not EOF(1)
Line Input #1, strLine
strLine = Replace(strLine, "abc", "efg")
strAll = strAll & strLine & vbCrLf
Loop
Close #1
Open "DestinationFileName" For Output As #2
Print #2, strAll
Close #2
Dim TempFile As Long
Dim LoadBytes() As ByteTempFile=FreeFile
Open 文件名 For Binary As #TempFile
Redim LoadBytes(1 To Lof(TempFile)) As Byte
Get #TempFile,,LoadBytes
Close TempFileText1.Text=StrConv(LoadBytes,vbUniCode)写入:
Dim TempFile As Long
Dim SaveBytes() As ByteSaveBytes=StrConv(Text1.Text,vbFromUniCode)TempFile=FreeFile
Open 文件名 For Binary As #TempFile
Put #TempFile,,SaveBytes
Close TempFile
谁能再帮帮我?

了
这有一个例子
'根据用户输入生成不定序列号,其值为S
s2 = ""
S = ""
s1 = ""
If txtuse.Text = "" Then
MsgBox "请输入用户名!", , "提示"
Else
s2 = txtuse.Text
For I = 1 To Len(txtuse.Text)
A = Left(txtuse.Text, I)
b = Right(A, 1)
m = Asc(b) - I
100:
If m >= 65 And m <= 90 Then
S = S + Chr(m)
Else
If m < 65 Then
m = m + I
Else
m = m - I
End If
GoTo 100
End If
Next
s1 = S
'生成固定长度
If Len(S) < 10 Then
For j = 1 To 10 - Len(s1)
d = Left(s1, I)
e = Right(d, 1)
k = Asc(e) - j
104:
If k >= 65 And k <= 90 Then
S = S + Chr(k)
Else
If k < 65 Then
k = k + j
Else
k = k - j
End If
GoTo 104
End If
Next
End If
txtserial.Text = S
