我现在开发一个发短信的软件,发送英文字符没有问题,但是如果发送中文字符,手机就会收到一堆的乱码。我吧要发送的字符用函数URLEncode转换成unicode字符也没有
Public Function URLEncode(sm As String) As String
Dim Sre As String
Dim i As Integer
For i = 0 To Len(sm) - 1
Sre = Sre & Hex(AscW(Mid(sm, i + 1, 1)))
Next
URLEncode = Sre
Debug.Print Sre
End Function请高手指点啊
Public Function URLEncode(sm As String) As String
Dim Sre As String
Dim i As Integer
For i = 0 To Len(sm) - 1
Sre = Sre & Hex(AscW(Mid(sm, i + 1, 1)))
Next
URLEncode = Sre
Debug.Print Sre
End Function请高手指点啊
Dim tep As String
Dim temp As String
Dim i As Integer
Dim b As Integer
tep = rmsg
i = Len(tep)
b = i / 4
If i = b * 4 Then
b = b - 1
tep = Left(tep, b * 4)
Else
tep = Left(tep, b * 4)
End If
chg = ""
For i = 1 To b
temp = "&H" & Mid(tep, (i - 1) * 4 + 1, 4)
chg = chg & ChrW(CInt(Val(temp)))
Next i
End Function
同上,为了发送以PDU模式发送短消息,必须将手机号码和对方手机号码也转换为PDU格式,下面的函数就是为了实现这种转换: Public Function telc(num As String) As String
Dim tl As Integer
Dim ltem, rtem, ttem As String
Dim ti As Integer
ttem = ""
tl = Len(num)
If tl <> 11 And tl <> 13 Then
MsgBox "wrong number." & tl
Exit Function
End If
If tl = 11 Then
tl = tl + 2
num = "86" & num
End If
For ti = 1 To tl Step 2
ltem = Mid(num, ti, 1)
rtem = Mid(num, ti + 1, 1)
If ti = tl Then rtem = "F"
ttem = ttem & rtem & ltem
Next ti
telc = ttem
End Function 手机号码有两种表示方法:11位和13位(带国家码86),一般手机发送时都是以13位形式表示的,所以以上的函数还有一个功能是自动将11位格式手机号码转换为13位形式,然后再转换为PDU串。
Const midx = "11000D91"
Const sufx = "000800"
Public Function Sendsms(csca As String, num As String, msg As String) As _Boolean
Dim pdu, psmsc, pnum, pmsg As String
Dim leng As String
Dim length As Integer
length = Len(msg)
length = 2 * length
leng = Hex(length)
If length < 16 Then leng = "0" & leng
psmsc = Trim(telc(csca))
pnum = Trim(telc(num))
pmsg = Trim(ascg(msg))
pdu = prex & psmsc & midx & pnum & sufx & leng & pmsg
sleep(1)
mobcomm.Output = "AT+CMGF=0" + vbCr
mobcomm.Output = "AT+CMGS=" & Str(15 + length) + vbCr
mobcomm.Output = pdu & Chr$(26)
sleep(1)
Sendsms = True
End Function 因为手机同一时间只能处理一件事情,因此这个函数只负责发送短信,关于短信发送成功与否以及阅读短信的部分集中在一起处理。判断手机短信发送成功与否主要由AT+CMGS命令执行以后的返回码来决定(可参见前文的AT指令介绍部分)。 为了防止手机因过于繁忙而出错,这里采取了一定的方法让手机有充分的时间处理发送和接收及删除等操作。Sleep()函数正是为此而设计的,在发送及删除操作后都会让程序暂停一秒,这样就不至于使得手机过于繁忙。
Dim si, sb As Integer
Dim stmp As Integer
Dim stemp As String
sb = Len(smsg)
ascg = ""
For si = 1 To sb
stmp = AscW(Mid(smsg, si, 1))
If Abs(stmp) < 127 Then
stemp = "00" & Hex(stmp)
Else
stemp = Hex(stmp)
End If
ascg = ascg & stemp
Next si
ascg = Trim(ascg)
End Function 2 手机短信接收函数 相对于短信的发送函数而言,短信的接收相当简单,只需要以下的三行代码就完成了。但是它使用的技术却决不比短信的发送少,这里主要用到了Mscomm控件的Output属性和AT+CMGR指令。 Public Sub readsms(rnum As String)
mobcomm.Output = "AT+CMGF=1" + vbCr
mobcomm.Output = "AT+CMGR=" & rnum + vbCr
End Sub
Hex是返回一个数值的十六进制表示形式.
hex(15) = 000F
如果你要转换到unicode字符,可以使用函数strconv(str,vbunicode)
你可以查查msdn上这个函数的帮助
Dim tep As String
Dim temp As String
Dim i As Integer
Dim b As Integer
tep = rmsg
i = Len(tep)
b = i / 4
If i = b * 4 Then
b = b - 1
tep = Left(tep, b * 4)
Else
tep = Left(tep, b * 4)
End If
chg = ""
For i = 1 To b
temp = "&H" & Mid(tep, (i - 1) * 4 + 1, 4)
chg = chg & ChrW(CInt(Val(temp)))
Next i
End Function 这个函数我没看明白是怎么回事,我试了一下chg("你好")没有返回任何结果
你能帮我解释一下这个函数吗,谢谢
用函数strconv(str,vbunicode)可以把字符串转换到unicode形式
用函数strconv(str,vbfromunicode)可以把字符串从unicode形式转换回来
//呵呵,这个要看在什么平台下开发如果是不支持unicode字符的系统,strconv(str,vbunicode)是没有作用的;
但是ascw()也同样,在不支持unicode的系统下,ascw和asc的作用相同.
也就是说,如果strconv(str,vbunicode)发挥不了作用,ascw同样发挥不了作用,所以我不同意你的观点.
