我可以使用Internet Explorer使用MS Access SQL Server连接到JavaScript，function connectToDB2() {
var connection = new ActiveXObject("ADODB.Connection");
var ConnString = "Data Source= . . ;
connection.open(ConnString);
}
，如下所示：
DB2是否可以连接到import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import com.independentsoft.exchange.Appointment;
import com.independentsoft.exchange.Body;
import com.independentsoft.exchange.Folder;
import com.independentsoft.exchange.ItemId;
import com.independentsoft.exchange.Service;
import com.independentsoft.exchange.ServiceException;
import com.independentsoft.exchange.StandardFolder;
import java.text.SimpleDateFormat;
import java.util.Date;
public class MyActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
new MyAsyncTask().execute();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
//Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class MyAsyncTask extends AsyncTask<String, Integer, String> {
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
String s=postData(params);
return s;
}
protected void onPostExecute(String result){
}
protected void onProgressUpdate(Integer... progress){
}
public String postData(String valueIWantToSend[]) {
String returnValue = "";
try {
Service service = new Service("https:192.168.2.105/ews/Exchange.asmx", "John","xxxxx");
Folder inboxFolder = service.getFolder(StandardFolder.INBOX);
Log.w("inboxFolder", inboxFolder.getDisplayName());
returnValue = inboxFolder.getDisplayName();
}
catch (ServiceException ex)
{
Log.w("ServiceException", ":" + ex.getFaultCode());
Log.w("ServiceException", ":" + ex.getFaultString());
Log.w("ServiceException", ":" + ex.getMessage());
Log.w("ServiceException", ":" + ex.getXmlMessage());
Log.w("ServiceException", ":" + ex.getResponseCode());
Log.w("ServiceException", ":" + ex.getRequestBody());
}
catch (Exception ex)
{
Log.w("Exception", ex.getMessage());
}
return returnValue;
}
}
}
？什么是连接字符串？
