Fetching query result for editbox

Question

Hello to everyone. I just started developing Windows application (after 2 years pause). So, I'm working 'with' MFC Dialog based app.
I want to fill combo box (or edit box it doesn't matter) with MySQL query result. I have these codes:
void CConnectToMySQLDlg::OnWriteToDatabase()
CString get, set;
m_edit.GetWindowText(get);
CT2CA temp_string(get);
string s_get(temp_string);
if (m_edit.GetWindowTextLength() != 0) // if you can please write this line better.
MySQL_Driver *driver;
Connection *dbConn;
Statement *statement;
ResultSet *result;
driver = get_mysql_driver_instance();
dbConn = driver->connect("tcp://127.0.0.1:3306", "root", "connection");
dbConn->setSchema("world");
statement = dbConn->createStatement();
result = statement->executeQuery(s_get);
//CStringArray comboArray;
/*comboArray.Add(_T("bir"));
comboArray.Add(_T("iki"));
comboArray.Add(_T("uc"));
comboArray.Add(_T("dord"));
comboArray.Add(_T("bes"));
comboArray.Add(_T("ffsfsfs"));
comboArray.Add(_T("bfsfsfsdes"));
comboArray.Add(_T("bczxczxes"));
comboArray.Add(_T("aadafdsbes"));
comboArray.Add(_T("zczxawfebes"));*/
//comboMysql.ResetContent();
string s_set = "string";
set.Format(_T("%S"), s_set.c_str());
while (result->next())
// here how can I set edit box value?
// So, how can I convert
AfxMessageBox(L"dsadasd");
delete result;
delete statement;
delete dbConn;
else // handling user input
AfxMessageBox(L"not allowed");
I can get input stream and successfully(1) execute it but I don't know how to set its result(s).
(1) --- In this case I entered this SQL line:
select ID, Name from city where ID = 1 or ID = 2 or ID = 3 or ID = 4
and it alerted me 4 times.
p.s. If there any problematic codes please tell me the correct variant(s).
Best regards,
Mirjalal.

I solved my problem. I pasted working codes below.
void CmysqlDlg::OnBnClickedButton1()
CString get, set, ComboString;
edit.GetWindowText(get);
CT2CA temp_string(get);
std::string s_get(temp_string);
if (edit.GetWindowTextLength() != 0) // if you can please write this line better.
MySQL_Driver *driver;
Connection *dbConn;
Statement *statement;
ResultSet *result;
driver = get_mysql_driver_instance();
dbConn = driver->connect("tcp://127.0.0.1:3306", "root", "connection");
dbConn->setSchema("world");
statement = dbConn->createStatement();
result = statement->executeQuery(s_get); // executes the user "input"
comboBox.ResetContent();
// ofstream y("text.txt"); // actually i don't need this anymore :P
while (result->next())
string name_string = result->getString("Name"); // Name is the my tbl column name
CString cs_name_string(name_string.c_str());
comboBox.AddString(cs_name_string);
delete result;
delete[] result;
delete statement;
delete[] statement;
delete dbConn;
delete[] dbConn;
else // handling user input
AfxMessageBox(L"olmaz");
Thanks.
