我是MFC的新手，也不具备C ++的丰富经验. 我正在尝试将编辑框中的数据发送到串行端口.到目前为止，我可以将字符串(LPCSTR)发送到WriteFile函数.现在，我需要将用户在editbox中以十六进制格式键入的数据发送到串行端口.当我输入0X6A或$ 6A时，我想以十六进制形式发送6A作为字符串. 有人可以帮忙吗? :confused:

I am new in MFC, not much experience in C++ either. I am trying to send data in edit box to serial port. I can send strings(LPCSTR) to WriteFile function as of now. Now I need to send data which user types in hex format in editbox to serial port. When I type say 0X6A or $6A i want to send 6A in hex otherwise as a string. Can anybody help please. :confused:

6A我想以六进制形式发送6A作为字符串. 有人可以帮忙吗? :confused: 6A i want to send 6A in hex otherwise as a string. Can anybody help please. :confused:

从十六进制表示形式(字符串)中获取一个字节几乎是一件微不足道的任务，您可以自己完成，也可以按照建议使用strtoul [ ^ ]函数或 [^ ]一. :) Getting a byte from its hexadecimal representation (string) is an almost trivial task, you may do it yourself or you may use, as suggested, strtoul [^] function or sscanf [^] one. :)

您可以使用strtoint转换输入字符串，它接受十进制或十六进制数字，这是指向msdn帮助的链接:- msdn.microsoft/zh-cn/library/bb773451(v = VS.85).aspx?appId = Dev10IDEF1& l = EN-US& k = k(STRTOINT); k (DevLang-"C ++")& rd = true [ ^ ] :) You could convert your input string using strtoint, it accepts decimal or hex numbers, here''s a link to the msdn help:- msdn.microsoft/en-us/library/bb773451(v=VS.85).aspx?appId=Dev10IDEF1&l=EN-US&k=k(STRTOINT);k(DevLang-"C++")&rd=true[^] :)
