在注册里的某个地方，具体想不起来了

看这下例子
void CODBCDlg::OnCreateDS()
{
UpdateData();
//写注册表。
HKEY hKey;
DWORD dwAction;
CString subkey="SoftWare\\ODBC\\ODBC.INI\\";
subkey+=m_dsn;
DWORD dwLen;

if(RegCreateKeyEx(HKEY_CURRENT_USER,subkey,
0,NULL,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,
NULL,&hKey,&dwAction)!=ERROR_SUCCESS)
{
MessageBox("Can't create the specified key.");
return;
}

dwLen=m_database.GetLength ();
RegSetValueEx(hKey,"Database",0,REG_SZ,(const BYTE *)m_database.GetBuffer (dwLen),
dwLen+1);
m_database.ReleaseBuffer ();

dwLen=m_user.GetLength();
RegSetValueEx(hKey,"LastUser",0,REG_SZ,(const BYTE *)m_user.GetBuffer(dwLen),dwLen+1);
m_user.ReleaseBuffer ();

dwLen=m_server.GetLength ();
RegSetValueEx(hKey,"Server",0,REG_SZ,(const BYTE *)m_server.GetBuffer (dwLen),dwLen+1);
m_server.ReleaseBuffer ();

RegSetValueEx(hKey,"Driver",0,REG_SZ,
(const BYTE *)"C:\\WINNT\\System32\\SQLSRV32.dll",31);

RegCloseKey(hKey);
}
