char* 转换成 LPCTSTR

char ch[1024] = "xxxx";int num = MultiByteToWideChar(0,0,ch,-1,NULL,0);wchar_t *wide = new wchar_t[num];MultiByteToWideChar(0,0,ch,-1,wide,num);

LPCTSTR 转换成 char *

wchar_t widestr[1024] = L"xxxx";int num = WideCharToMultiByte(CP_OEMCP,NULL,widestr,-1,NULL,0,NULL,FALSE);char *pchar = new char[num];WideCharToMultiByte (CP_OEMCP,NULL,widestr,-1,pchar,num,NULL,FALSE);

 

如果是一个路径里面有//,有的时候需要替换为\

#include 
     
      CString subfile1 = subfile.Left(subfile.ReverseFind('.'));subfile1.Replace('\\','/');USES_CONVERSION;m_db->UpDataPicDir((char*)T2A(subfile1), backid);
     

 char* 转CString

char* pData = "1234";CString strData(pData);

宽字符的拼接

 TCHAR buf[255];

wsprintf(buf, _T("RegisterUploadMinFile  %s ok！ \n"), A2T(strFileName.c_str()));

 

 

CString强转int

mORDERINFO.back_id= _ttoi(CString((*p)["back_id"].asString().c_str()));
