  • Searching a keyword in a long string in mysql?

    - by user187580
    Hello keyword = house SELECT * FROM products WHERE description LIKE '%house%' This query also returns records having keyword, for example, courthouse, but I want to look for house only. How do I search anywhere in the description for "house" only? Thanks. UPDATE just for more clarification .. actually house, can be at - the start of the description .. "House for sale..", - can be quoted -- "house", 'house' - can have exclamation .. house!!!, house! - others - house? etc .. this is why I used %house%

  • Flash: Correctly handling click-and-drag outside the browser?

    - by David Wolever
    What's the correct way to detect, from Flash, when someone has started a drag within the browser (eg, a MOUSE_DOWN event), dragged the mouse outside the browser window, released the button, then moved the mouse back over the browser? For example (assuming StackOverflow was a Flash application): I've tried the "obvious" thing, checking event.buttonDown in the MOUSE_MOVE handler, but even though the mouse button is up, event.buttonDown is true in step 2 (above). So, is there any other way to check the "real" status of the mouse button? Or any other way to handle this situation?

  • In LaTeX, is there a way to get long lines along the margins?

    - by Christian Jonassen
    I'm working on a report, and some elements are outside the margins (but some are just barely outside the margins). I was wondering: Is there a way to make two vertical lines, one on each side, along the margins so that one can easily see if it goes outside them? (Googling it, I only found information about margin notes.) A figure is below: |report text goes here| |more text goes also h|ere |and so on and so fort|h It would certainly make correcting these kinds of mistakes very trivial. :) Feel free to post answers that would solve/show this problem in a more "LaTeX-correct" way, if that makes any sense at all.

  • Java long task - Did it stop writing to file?

    - by rockit
    I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

  • How do I wrap a very long line of text in a GWT label?

    - by user323295
    This is an extract of my code at the moment: VerticalPanel mainPanel = new VerticalPanel(); RootPanel.get("messages").add(mainPanel); HorizontalPanel tempPanel = new HorizontalPanel(); tempPanel.setSize("100px", "200px"); Label content = new Label("AAAveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongtextZZZ"); content.setWidth("50px"); content.setWordWrap(true); tempPanel.add(content); mainPanel.add(tempPanel); The label displays but it does not wrap. If I insert a space it seems that word wrap works, but I guess I want character wrap. Any ideas? I do not want a horizontal scrollbar.

  • Why does this simple MySQL procedure take way too long to complete?

    - by Howard Guo
    This is a very simple MySQL stored procedure. Cursor "commission" has only 3000 records, but the procedure call takes more than 30 seconds to run. Why is that? DELIMITER // DROP PROCEDURE IF EXISTS apply_credit// CREATE PROCEDURE apply_credit() BEGIN DECLARE done tinyint DEFAULT 0; DECLARE _pk_id INT; DECLARE _eid, _source VARCHAR(255); DECLARE _lh_revenue, _acc_revenue, _project_carrier_expense, _carrier_lh, _carrier_acc, _gross_margin, _fsc_revenue, _revenue, _load_count DECIMAL; DECLARE commission CURSOR FOR SELECT pk_id, eid, source, lh_revenue, acc_revenue, project_carrier_expense, carrier_lh, carrier_acc, gross_margin, fsc_revenue, revenue, load_count FROM ct_sales_commission; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; DELETE FROM debug; OPEN commission; REPEAT FETCH commission INTO _pk_id, _eid, _source, _lh_revenue, _acc_revenue, _project_carrier_expense, _carrier_lh, _carrier_acc, _gross_margin, _fsc_revenue, _revenue, _load_count; INSERT INTO debug VALUES(concat('row ', _pk_id)); UNTIL done = 1 END REPEAT; CLOSE commission; END// DELIMITER ; CALL apply_credit(); SELECT * FROM debug;

  • Is there anything inherently wrong with long variable/method names in Java?

    - by Doug Smith
    I know this is probably is a question of personal opinion, but I want to know what's standard practice and what would be frowned upon. One of my profs in university always seems to make his variable and method names as short as possible (getAmt() instead of getAmount) for instance. I have no objection to this, but personally, I prefer to have mine a little longer if it adds descriptiveness so the person reading it won't have to check or refer to documentation. For instance, we made a method that given a list of players, returns the player who scored the most goals. I made the method getPlayerWithMostGoals(), is this wrong? I toiled over choosing a way to make it shorter for awhile, but then I thought "why?". It gets the point across clearly and Eclipse makes it easy to autocomplete it when I type. I'm just wondering if the short variable names are a piece of the past due to needing everything to be as small as possible to be efficient. Is this still a requirement?

  • Android: How to set the contents of a Edit text from a Button click?

    - by primal
    Hi, I am a rookie to android. I am thinking of implementing a simple calculator in android to get a hold of the basics in android. I want to display a keypad with numbers and mathematical operations and when the user presses the keys the corresponding number is displayed in edit text. I tried using gettext() and updating the contents of edit text but it shows just the contents of pressed button. Also how do I read the contents of button so as to do mathematical operations in code? Any help would be much appreciated. regards, Primal

  • file_get_contents returns an empty string that is 354 bytes long.

    - by Kendall Crouch
    I'm trying to read the contents of a file and simply getting an empty string. The file exists on the server. I've tried some test with the following code and get the true to display: $filename = "includes/blah.php"; $filecontents = file_get_contents($filename, FILE_USE_INCLUDE_PATH); if ($filecontents === false) { echo(":FALSE:"); } else { echo(":TRUE:"); } var_dump($filecontents); The dump displays "string(354)" which is the correct size of the file. What am I doing wrong?

  • In jQuery, is there any way to only bind a click once?

    - by Chris Henry
    I have an ajax app that will run functions on every interaction. I'd like to be able to run my setup function each time so all my setup code for that function remains encapsulated. However, binding elements more than once means that the handler will run more than once, which is obviously undesirable. Is there an elegant way in jQuery to call bind on an element more than once without the handler being called more than once?

  • how to get the exact mouse click position with support for variable screen resolution ?

    - by javadahut
    I'm writing a simple macro program: you record your mouse or keyboard movements, you save the file, and the program will run it for you on your pc computer. however, the situation is, what if the file is run on a laptop where the resolution is smaller? what if the file is to be run on a web server where there is no monitor ? ie) the button is clicked at position (x,y): 300,520 but the button will be at another location in a different monitor resolution. How would you approach this problem ?

  • How can a button click method find out which item is selected in a ListView?

    - by Ian Bayley
    I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result. I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems. Here's the code (without the modification which didn't work) package com.bayley; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import java.util.ArrayList; /** * * @author p0074564 */ public class September extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); final ListView myListView = (ListView) findViewById(R.id.myListView); Button addButton = (Button) findViewById(R.id.AddButton); Button deleteButton = (Button) findViewById(R.id.DeleteButton); final EditText editText = (EditText) findViewById(R.id.myEditText); final ArrayList<String> todoItems = new ArrayList<String>(); todoItems.add("Monday"); todoItems.add("Tuesday"); todoItems.add("Wednesday"); final ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, todoItems); myListView.setAdapter(aa); addButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { todoItems.add(editText.getText().toString()); aa.notifyDataSetChanged(); } }); deleteButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { // always returns -1 unfortunately ie nothing is ever selected int index = myListView.getSelectedItemPosition(); if (index >= 0) { todoItems.remove(index); } aa.notifyDataSetChanged(); } }); } }

  • is there a way to compress a GET string so it won't be so long?

    - by sct
    I need to compress a string so it is shorter for a GET method form. Is there any way to compress a string and it will be decrypted later? That way... ?error=LOTS OF STUFFLOTS OF STUFFLOTS OF STUFFLOTS OF STUFFLOTS OF STUFF is shorter in some sort of key ?error=somekey so I can get back the result later. Not using MySQL preferably. Anyone know a good method for this?

  • How to detect when a long download is finished in a web server?

    - by Shabbyrobe
    I need a web server that allows me to remove a file after it has been successfully downloaded once. Is there any way to do this with apache? Is there another web server I can use for this task? I had already looked into Tornado for this purpose, but couldn't find a way to get an event to fire as soon as the download finished. the on_connection_close would only fire when I shut down the server. I'd prefer something PHP or Python-based if I have to code it myself.

  • How to detect .NET WPF memory leak or GC long run?

    - by Néstor Sánchez A.
    I have the next very strange situation and problem: .NET 4.0 application for diagram editing (WPF). Runs ok in my PC: 8GM RAM, 3.0GHz, i7 quad-core. While creating objects (mostly diagram nodes and connectors, plus all the undo/redo information) the TaskManager show, as expected, some memory usage "jumps" (up and down). These mem-usage "jumps" also remains executing AFTER user interaction ended. Maybe this is the GC cleaning/regorganizing memory? To see what is going on, I've used the Ants mem profiler, but somewhat it prevents those "jumps" to happen after user interaction. PROBLEM: It Freezes/Hangs after seconds or minutes of usage in some slow/weak laptos/netbooks of my beta testers (under 2GHz of speed and under 2GB of RAM). I was thinking of a memory leak, but... EDIT: Also, there is the case that the memory usage grows and grows until collapse (only in slow machines). In a Windows XP Mode machine (VM in Win 7) with only 512MB of RAM Assigned it works fine without mem-usage "jumps" after user interaction (no GC cleaning?!). So, I really have a big trouble because I cannot reproduce the error, only see these strange behaviour (mem jumps), and the tool supposed to show me what is happening is hiding the problem (like the "observer's paradox"). Any ideas on what's happening and how to solve it?

  • Handling a button click in MVC, why is there a string parameter?

    - by SLC
    I'm following this awful textbook, going through the basics of create/edit/delete records. The delete bit has a confirm button, and it is handled like so: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id, string confirmButton) { It offers no explanation of why the button is passed as a string or how MVC interprets it. Can anyone help clarify what's going on here? The Create code has no such string being passed.
