sql语句问题！！
如何过滤sql语句中的特殊字符
将下面代码插入数据库出现操作符丢失错误（有特殊字符）。插入其他的都正常，
我已经过滤了 " ' 两个字符。怎么还不行啊
字段是是字符型的
要插入数据库的代码如下。
function getpychar(char)
tmp=65536+asc(char)
if(tmp>=45217 and tmp<=45252) then
getpychar= "A"
elseif(tmp>=45253 and tmp<=45760) then
getpychar= "B"
elseif(tmp>=45761 and tmp<=46317) then
getpychar= "C"
elseif(tmp>=46318 and tmp<=46825) then
getpychar= "D"
elseif(tmp>=46826 and tmp<=47009) then
getpychar= "E"
elseif(tmp>=47010 and tmp<=47296) then
getpychar= "F"
elseif(tmp>=47297 and tmp<=47613) then
getpychar= "G"
elseif(tmp>=47614 and tmp<=48118) then
getpychar= "H"
elseif(tmp>=48119 and tmp<=49061) then
getpychar= "J"

Con = (Replace(Text1.Text, """", Chr(34)))
Con = Replace(Con, "'", Chr(39))
我晕,你这跟没替换一个样!!替换完之后根本就没变啊!~~~~~~

MCCmd是自己定义的函数。执行sql语句的
Public Function MCCmd(SQL As String)
Set Cmd = CreateObject("ADODB.Command")
Cmd.ActiveConnection = Conn
Cmd.CommandText = SQL
Cmd.CommandType = 1
Cmd.CommandTimeout = 0
Cmd.Prepared = True
Set MCCmd = Cmd.Execute()
T = MsgBox("操作成功！", vbOKOnly, "操作成功")
End Function
Public Function MCCmd(SQL As String)
Set Cmd = CreateObject("ADODB.Command")
Cmd.ActiveConnection = Conn
Cmd.CommandText = SQL
Cmd.CommandType = 1
Cmd.CommandTimeout = 0
Cmd.Prepared = True
Set MCCmd = Cmd.Execute()
T = MsgBox("操作成功！", vbOKOnly, "操作成功")
End Function

源代码如下：
Con = (Replace(Text1.Text, """", Chr(34)))
Con = Replace(Con, "'", Chr(39))
MCCmd "Insert into code (Subject,Content,Type,ind) values('" & Text3.Text & "','" & Con & "','" & Combo1.Text & "',#" & Text2.Text & "#)"
Text1.Text = ""
Text2.Text = Now()
Text3.Text = ""
Combo1.Text = ""
Rec ("select * from [Type]")
Combo1.Clear
While Not Rs.EOF
Combo1.AddItem Rs(0)
Rs.MoveNext
Wend
Con = (Replace(Text1.Text, """", Chr(34)))
Con = Replace(Con, "'", Chr(39))
MCCmd "Insert into code (Subject,Content,Type,ind) values('" & Text3.Text & "','" & Con & "','" & Combo1.Text & "',#" & Text2.Text & "#)"
Text1.Text = ""
Text2.Text = Now()
Text3.Text = ""
Combo1.Text = ""
Rec ("select * from [Type]")
Combo1.Clear
While Not Rs.EOF
Combo1.AddItem Rs(0)
Rs.MoveNext
Wend
