全角半角转换方法-优快云博客

本文链接：https://blog.youkuaiyun.com/nicolas16/article/details/1935761

全角和半角的转化可以在输入时就指定输入法(方法一),也可以采用对照表(方法二)(可以改进),也可以采用函数直接转化(方法三)(最简单).这三种方法都来自网上,经测试,方法二和方法三都可以解决问题,而且方法二和三都很好封装成一个通用函数,推荐.

方法一:
HWND hWnd= GetDlgItem(IDC_EDT_NUMBER)->m_hWnd;
HIMC hImc;
DWORD dwConvMode, dwSentMode;
hImc = ImmGetContext(hWnd);
ImmGetConversionStatus(hImc, &dwConvMode, &dwSentMode);
ImmSetConversionStatus(hImc, dwConvMode&~IME_CMODE_FULLSHAPE, dwSentMode);
方法二:
void   Str2GBReplace(CString   &mString)
{
// mString.Replace(_T(" "), _T("　"));
// mString.Replace(_T("!"),   _T("！"));
// mString.Replace(_T(""""),   "＂");

方法三:

//変換方法
DWORD flags = LCMAP_FULLWIDTH; //全角文字にします（適用される場合）。
//DWORD flags = LCMAP_HALFWIDTH; //半角文字にします（適用される場合）。
//DWORD flags = LCMAP_HIRAGANA; //ひらがなにします。
//DWORD flags = LCMAP_KATAKANA; //カタカナにします。
const int size = text.Length() * 2 + 1;
char* s = new char[size];
try
{
ZeroMemory(s, size);
LCMapString(GetUserDefaultLCID(),
              flags,
              text.c_str(),
              text.Length() + 1,
              s,
              size);
AnsiString newtext = s; //変換した文字列
return newtext;
}
__finally
{
delete[] s;
}
