用VB6.0编写手机短信发送
因为手机短消息的发送是以PDU串的形式发送出去的,中文字符以Unicode码来表示,所以在发送中文短消息之前必须首先将中文字符转换为Unicode码,下面的函数将实现这个功能。这个函数主要应用到VB自带的一个格式转换函数:ChrW()将中文转换为Unicode码。
Public Function chg(rmsg As String) As String
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
