typedef   BOOL   (WINAPI   *LPFN_ISWOW64PROCESS)   (HANDLE,   PBOOL); LPFN_ISWOW64PROCESS   fnIsWow64Process   =   (LPFN_ISWOW64PROCESS)GetProcAddress(GetModuleHandle("kernel32"), "IsWow64Process"); CString GetSystemIsWow64() { BOOL  bIsWow64   =   FALSE; CString str64;if   (NULL   !=   fnIsWow64Process) { if   (!fnIsWow64Process(GetCurrentProcess(),&bIsWow64)) {MessageBox(0,"Handle Error!",0,0);} } if (bIsWow64 == true){str64 = "64位";}else{str64 = "32位";}return str64;}
