  • Forced closed only when put alphabetical string in edit text

    - by Abdullah Al Mubarok
    So, I make a checker if an id is in the database or not, the id is in numerical string, the type in database is char(6) though. So this is my code public class input extends Activity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.input); final EditText edittext = (EditText)findViewById(R.id.editText1); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub String nopel = edittext.getText().toString(); if(nopel.length() == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("nopel", nopel)); JSON json_dp = new JSON(); JSONObject jobj_dp = json_dp.getJSON("http://10.0.2.2/KP/pdam/nopel.php", pairs); try { if(jobj_dp.getInt("row") == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ String snopel = jobj_dp.getString("nopel"); String snama = jobj_dp.getString("nama"); String salamat = jobj_dp.getString("alamat"); String sgolongan = jobj_dp.getString("golongan"); Intent i = new Intent(input.this, list.class); i.putExtra("nopel", snopel); i.putExtra("nama", snama); i.putExtra("alamat", salamat); i.putExtra("golongan", sgolongan); startActivity(i); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); } } the first check is to check if an input is null, it's going right for now, the second check is to check if an id in the database, and it's the problem. When I try some id in numerical value like "0001" or "02013" it's fine, and can run. but when I just got to put "abushd" it forced close. anyone know why I got this?

  • .NET Web Browser Control - SaveAs Event

    - by Dale
    Does anybody know if you can access the SaevFileDialog control that's used by the WebBrowser control? Once somebody saves the webpage being displayed I need to catch where the files have been created; however I can't seem to find any events/members that allow me access to that information.

  • Thread sleep and thread join.

    - by Dhruv Gairola
    hi guys, if i put a thread to sleep in a loop, netbeans gives me a caution saying Invoking Thread.sleep in loop can cause performance problems. However, if i were to replace the sleep with join, no such caution is given. Both versions compile and work fine tho. My code is below (check the last few lines for "Thread.sleep() vs t.join()"). public class Test{ //Display a message, preceded by the name of the current thread static void threadMessage(String message) { String threadName = Thread.currentThread().getName(); System.out.format("%s: %s%n", threadName, message); } private static class MessageLoop implements Runnable { public void run() { String importantInfo[] = { "Mares eat oats", "Does eat oats", "Little lambs eat ivy", "A kid will eat ivy too" }; try { for (int i = 0; i < importantInfo.length; i++) { //Pause for 4 seconds Thread.sleep(4000); //Print a message threadMessage(importantInfo[i]); } } catch (InterruptedException e) { threadMessage("I wasn't done!"); } } } public static void main(String args[]) throws InterruptedException { //Delay, in milliseconds before we interrupt MessageLoop //thread (default one hour). long patience = 1000 * 60 * 60; //If command line argument present, gives patience in seconds. if (args.length > 0) { try { patience = Long.parseLong(args[0]) * 1000; } catch (NumberFormatException e) { System.err.println("Argument must be an integer."); System.exit(1); } } threadMessage("Starting MessageLoop thread"); long startTime = System.currentTimeMillis(); Thread t = new Thread(new MessageLoop()); t.start(); threadMessage("Waiting for MessageLoop thread to finish"); //loop until MessageLoop thread exits while (t.isAlive()) { threadMessage("Still waiting..."); //Wait maximum of 1 second for MessageLoop thread to //finish. /*******LOOK HERE**********************/ Thread.sleep(1000);//issues caution unlike t.join(1000) /**************************************/ if (((System.currentTimeMillis() - startTime) > patience) && t.isAlive()) { threadMessage("Tired of waiting!"); t.interrupt(); //Shouldn't be long now -- wait indefinitely t.join(); } } threadMessage("Finally!"); } } As i understand it, join waits for the other thread to complete, but in this case, arent both sleep and join doing the same thing? Then why does netbeans throw the caution?

  • Android: Issue with acceptable file types via bluetooth

    - by poeschlorn
    Hi guys, i've got a problem with pushing files to my nexus one: It seems to me that there is only a small selection of file types that are accepted by my phone (such like jpg, gif and so on). I recently tried to push other files to my phone (in my case gpx) and my phone has rejected it automatically... is there a way to bypass or extent this filter? Is there also a way to catch those files by a service? greets, poeschlorn

  • Why should I use PropertyProxyValidator? ASP.NET

    - by user102533
    I understand thatthe PropertyProxyValidator integrates with the ASP.NET UI. But, it cannot do client side validation. How would it be any different from throwing in a label in the UI and populating the errors on the server side? Also, If I am using Validation Application Block, what approaches do you suggest for client side validation if I don't want to duplicate rules on server and client side?

  • two AES implementations generated different encryption results

    - by YCL
    I have an application that uses an opensource "libgcrypt" to encrypt/decrypt a data block (32 bytes). Now I am going to use Microsoft CryptAPI to replace it. My problem is that the libgcrypt and cryptApi approaches generate different ciphertext contents as I use the same AES-256 algoritjm in CFB mode, same key, and same IV, although the ciphertext can be decrypted by their own correspndingly. Could some tell me what is the problem? Thanks.

  • PHP's DOMXPath is stripping out my tags inside the matched text.

    - by Mint
    I asked this question yesterday, and at the time it was just what I needed, but while working with some live data I discovered that is wasn't quite doing what I expected. http://stackoverflow.com/questions/2571232/parse-html-with-phps-html-domdocument I gets the data from the HTML page, but then it also strips out all the HTML tags inside the captured block of text, which isn't what I want. (I might wan't to take some of the tags out, but not all, and this can be done later)

  • How to create a database deadlock using jdbc and JUNIT

    - by Isawpalmetto
    I am trying to create a database deadlock and I am using JUnit. I have two concurrent tests running which are both updating the same row in a table over and over again in a loop. My idea is that you update say row A in Table A and then row B in Table B over and over again in one test. Then at the same time you update row B table B and then row A Table A over and over again. From my understanding this should eventually result in a deadlock. Here is the code For the first test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Egypt"; int bpl = 0; stmt = c.createStatement(); rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); //ex.getMessage(); } } And here is the code for the second test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Jordan"; int bpl = 0; stmt = c.createStatement(); //stmt.close(); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); } } I am running these two separate JUnit tests at the same time and am connecting to an apache Derby database that I am running in network mode within Eclipse. Can anyone help me figure out why a deadlock is not occurring? Perhaps I am using JUnit wrong.

  • Twitter Bootstrap Navbar blocking svg viewBox

    - by user1167650
    I have a navbar fixed to the bottom and I have page that has a title and a giant svg (created by d3.js). I would like the svg to take up the entire screen (whatever is left over), but it always seems to have some part appear behind the bottom nav bar. I've tried: 1) using viewBox to auto-resize, setting the parent div and the svg to be block elements 2) adding padding-bottom to the body element But the svg still appears behind the navbar on wide screen monitors.

  • How to replace a region in emacs with yank buffer contents?

    - by Mad Wombat
    When I use VIM or most modeless editors (Eclipse, NetBeans etc.) I frequently do the following. If I have similar text blocks and I need to change them all, I will change one, copy it (or use non-deleting yank), select next block I need and paste the changed version over it. If I do the same thing in emacs (select region and paste with C-y), it doesn't replace the region, it just pastes at the cursor position. What is the way to do this in emacs?
