2010-10-24 11:06:57 来源:WEB开发网核心提示:以下四个函数分别实现:大五码转GBK码/GBK转大五码GB2312码转GBK码/GBK码转GB2312码//---// 大五码转GBK码:void __fastcall BIG52GBK(char *szBuf){ if(!strcmp(szBuf, "")) return; int nStrLen
以下四个函数分别实现:
大五码转GBK码/GBK转大五码
GB2312码转GBK码/GBK码转GB2312码
//--------------------------------------------------------------------------- // 大五码转GBK码: void __fastcall BIG52GBK(char *szBuf) { if(!strcmp(szBuf, "")) return; int nStrLen = strlen(szBuf); wchar_t *pws = new wchar_t[nStrLen + 1]; try { int nReturn = MultiByteToWideChar(950, 0, szBuf, nStrLen, pws, nStrLen + 1); BOOL bValue = false; nReturn = WideCharToMultiByte(936, 0, pws, nReturn, szBuf, nStrLen + 1, "?", &bValue); szBuf[nReturn] = 0; } __finally { delete[] pws; } } //--------------------------------------------------------------------------- // GBK转大五码 void __fastcall GBK2BIG5(char *szBuf) { if(!strcmp(szBuf, "")) return ; int nStrLen = strlen(szBuf); wchar_t *pws = new wchar_t[nStrLen + 1]; try { MultiByteToWideChar(936, 0, szBuf, nStrLen, pws, nStrLen + 1); BOOL bValue = false; WideCharToMultiByte(950, 0, pws, nStrLen, szBuf, nStrLen + 1, "?", &bValue); szBuf[nStrLen] = 0; } __finally { delete[] pws; } } //---------------------------------------------------------------------------- // GB2312码转GBK码 void __fastcall GB2GBK(char *szBuf) { if(!strcmp(szBuf, "")) return; int nStrLen = strlen(szBuf); WORD wLCID = MAKELCID(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED), SORT_CHINESE_PRC); int nReturn = LCMapString(wLCID, LCMAP_TRADITIONAL_CHINESE, szBuf, nStrLen, NULL, 0); if(!nReturn) return; char *pcBuf = new char[nReturn + 1]; try { wLCID = MAKELCID(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED), SORT_CHINESE_PRC); LCMapString(wLCID, LCMAP_TRADITIONAL_CHINESE, szBuf, nReturn, pcBuf, nReturn + 1); strncpy(szBuf, pcBuf, nReturn); } __finally { delete[] pcBuf; } } //--------------------------------------------------------------------------- // GBK码转GB2312码 void __fastcall GBK2GB(char *szBuf) { if(!strcmp(szBuf, "")) return; int nStrLen = strlen(szBuf); WORD wLCID = MAKELCID(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED), SORT_CHINESE_BIG5); int nReturn = LCMapString(wLCID, LCMAP_SIMPLIFIED_CHINESE, szBuf, nStrLen, NULL, 0); if(!nReturn) return; char *pcBuf = new char[nReturn + 1]; try { wLCID = MAKELCID(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED), SORT_CHINESE_BIG5); LCMapString(wLCID, LCMAP_SIMPLIFIED_CHINESE, szBuf, nReturn, pcBuf, nReturn + 1); strncpy(szBuf, pcBuf, nReturn); } __finally { delete []pcBuf; } } //--------------------------------------------------------------------------- // 测试代码 void __fastcall TForm1::Button1Click(TObject *Sender) { char szBuf[255]; // 从GB2312转到GBK strcpy(szBuf, Edit1->Text.c_str()); GB2GBK(szBuf); Edit2->Text = String(szBuf); // 从GB2312转到BIG5,通过GBK中转 strcpy(szBuf, Edit1->Text.c_str()); GB2GBK(szBuf); GBK2BIG5(szBuf); Edit3->Text = String(szBuf); }
