  • switching default keyevents actions after key combinations

    - by liysd
    I need to change default actions of two events. When I press "enter" one action occurs, when I press "shift-enter" another. I need to switch it. I means if I press "enter" than "shift-enter" action occurs. I tried something like this but if doesn't work. f(evt.keyCode == 13) { if(!evt.shiftKey){ evt.preventDefault(); evt.shiftKey = true; var e = jQuery.Event("keydown"); e.which = 13; e.shiftKey = true; $(wym._doc).trigger(e); Is there any way to do it?

  • Registry key editing vb6 startup

    - by Francesco D.
    Is it possible that someone here could explain how to use this code. Please keep in mind i am a complete amateur, so simplifications may be needed. Private Const cPGM = "C:\VB Forum\startup\Example.exe" Dim oShell As IWshShell_Class Set oShell = New IWshShell_Class oShell.RegWrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Run\MyVBApp", _ cPGM, "REG_SZ" How exactly is this code used? Is it saved as an .exe file and ran or what? Thanks for your prompt reply and informational feedback.

  • "Undefined index" when quoting array key

    - by Satish
    I have a form in index.php <?php echo '<form action="update_act.php" method="POST">'; echo '<input type="submit" name="'.$row['act_name'].'" value="edit"> echo </form> ?> Here $row['act_name'] is a value fetched from database. My update_act.php file is <?php echo "Old Activity Name : ".$_POST['$row[\'act_name\']']; ?> But I am getting an error Undefined index: $row['act_name'] in C:\wamp\www\ps\activity\update_act.php. I want to have different names for different submits but I am not able to get its value in another page. Is there any way for it?

  • Stopping the animation after you let go of a key

    - by Michael Zeuner
    What I have right now is an animation that starts when I press space: if(input.isKeyDown(Input.KEY_SPACE)) player = movingRightSwingingSword; However when I stop clicking space my animation continues. until I move my player, how do I make it so it stops the animation right when you let go of space?

  • Stop invalid data in a attribute with foreign key constraint using triggers?

    - by Eternal Learner
    How to specify a trigger which checks if the data inserted into a tables foreign key attribute, actually exists in the references table. If it exist no action should be performed , else the trigger should delete the inserted tuple. Eg: Consider have 2 tables R(A int Primary Key) and S(B int Primary Key , A int Foreign Key References R(A) ) . I have written a trigger like this : Create Trigger DelS BEFORE INSERT ON S FOR EACH ROW BEGIN Delete FROM S where New.A <> ( Select * from R;) ); End; I am sure I am making a mistake while specifying the inner sub query within the Begin and end Blocks of the trigger. My question is how do I make such a trigger ?

  • What exactly is a "key container"?

    - by saugata
    Is it something specific, with a definite structure, or just an arbitrary data file with some form of encryption to hold keys, and potentially other secret information? Can someone please explain the term or point me to a link.

  • c# winforms events restore textbox contents on escape

    - by aj3jr
    Using c# in 2008 Express. I have a textbox containing a path. I append a "\" at the end on Leave Event. If the user presses 'Escape' key I want the old contents to be restored. When I type over all the text and press 'Escape' I hear a thump and the old text isn't restored. Here what I have so far ... public string _path; public string _oldPath; this.txtPath.KeyPress += new System.Windows.Forms.KeyPressEventHandler(txtPath_CheckKeys); this.txtPath.Enter +=new EventHandler(txtPath_Enter); this.txtPath.LostFocus += new EventHandler(txtPath_LostFocus); public void txtPath_CheckKeys(object sender, KeyPressEventArgs kpe) { if (kpe.KeyChar == (char)27) { _path = _oldPath; } } public void txtPath_Enter(object sender, EventArgs e) { //AppendSlash(sender, e); _oldPath = _path; } void txtPath_LostFocus(object sender, EventArgs e) { //throw new NotImplementedException(); AppendSlash(sender, e); } public void AppendSlash(object sender, EventArgs e) { //add a slash to the end of the txtPath string on ANY change except a restore this.txtPath.Text += @"\"; } Thanks in advance,

  • (Python) algorithm to randomly select a key based on proportionality/weight

    - by LaundroMat
    Hi - I'm a bit at a loss as to how to find a clean algorithm for doing the following: Suppose I have a dict k: >>> k = {'A': 68, 'B': 62, 'C': 47, 'D': 16, 'E': 81} I now want to randomly select one of these keys, based on the 'weight' they have in the total (i.e. sum) amount of keys. >>> sum(k.values()) >>> 274 So that there's a >>> 68.0/274.0 >>> 0.24817518248175183 24.81% percent change that A is selected. How would you write an algorithm that takes care of this? In other words, that makes sure that on 10.000 random picks, A will be selected 2.481 times?

  • what's the performance difference between int and varchar for primary keys

    - by user568576
    I need to create a primary key scheme for a system that will need peer to peer replication. So I'm planning to combine a unique system ID and a sequential number in some way to come up with unique ID's. I want to make sure I'll never run out of ID's, so I'm thinking about using a varchar field, since I could always add another character if I start running out. But I've read that integers are better optimized for this. So I have some questions... 1) Are integers really better optimized? And if they are, how much of a performance difference is there between varchars and integers? I'm going to use firebird for now. But I may switch later. Or possibly support multiple db's. So I'm looking for generalizations, if that's possible. 2) If integers are significantly better optimized, why is that? And is it likely that varchars will catch up in the future, so eventually it won't matter anyway? My varchar keys won't have any meaning, except for the unique system ID part. But I may want to obscure that somehow. Also, I plan to efficiently use all the bits of each character. I don't, for example, plan to code the integer 123 as the character string "123". So I don't think varchars will require more space than integers.

  • how to hook key event.

    - by backspace7
    I'd like to limit the text length of EditText widget, And if user type more charactes than the limited length, I want to show a kind of warning popup, however I can't show popup. The problem is that we can't show popup while typing, Probably, many people think a way of utilizing OnKeyListener or OnKeyDown. But, when the word is composing, nothing come into OnKeyListener or OnKeyDown, So, we can't show popup when we want to. Is there anyone who have smart idea to solve this problem?

  • What are the hibernate annotations used to persist a Map with an enumerated type as a key?

    - by Jason Novak
    I am having trouble getting the right hibernate annotations to use on a Map with an enumerated class as a key. Here is a simplified (and extremely contrived) example. public class Thing { public String id; public Letter startLetter; public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } public enum Letter { A, B, C, D } Here are my current annotations on Thing @Entity public class Thing { @Id public String id; @Enumerated(EnumType.STRING) public Letter startLetter; @CollectionOfElements @JoinTable(name = "Thing_letterFrequencies", joinColumns = @JoinColumn(name = "thingId")) @MapKey(columns = @Column(name = "letter", nullable = false)) @Column(name = "count") public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } Hibernate generates the following DDL to create the tables for my MySql database create table Thing (id varchar(255) not null, startLetter varchar(255), primary key (id)) type=InnoDB; create table Thing_letterFrequencies (thingId varchar(255) not null, count double precision, letter tinyblob not null, primary key (thingId, letter)) type=InnoDB; Notice that hibernate tries to define letter (my map key) as a tinyblob, however it defines startLetter as a varchar(255) even though both are of the enumerated type Letter. When I try to create the tables I see the following error BLOB/TEXT column 'letter' used in key specification without a key length I googled this error and it appears that MySql has issues when you try to make a tinyblob column part of a primary key, which is what hibernate needs to do with the Thing_letterFrequencies table. So I would rather have letter mapped to a varchar(255) the way startLetter is. Unfortunately, I've been fussing with the MapKey annotation for a while now and haven't been able to make this work. I've also tried @MapKeyManyToMany(targetEntity=Product.class) without success. Can anyone tell me what are the correct annotations for my letterCounts map so that hibernate will treat the letterCounts map key the same way it does startLetter?

  • Ruby 1.9: turn these 4 arrays into hash of key/value pairs

    - by randombits
    I have four arrays that are coming in from the client. Let's say that there is an array of names, birth dates, favorite color and location. The idea is I want a hash later where each name will have a hash with respective attributes: Example date coming from the client: [name0, name1, name2, name3] [loc0, loc1] [favcololor0, favcolor1] [bd0, bd1, bd2, bd3, bd4, bd5] Output I'd like to achieve: name0 => { location => loc0, favcolor => favcolor0, bd => bd0 } name1 => { location => loc1, favcolor => favcolor1, bd => bd1 } name2 => { location => nil, favcolor => nil, bd => bd2 } name3 => { location => nil, favcolor => nil, bd => bd3 } I want to have an array at the end of the day where I can iterate and work on each particular person hash. There need not be an equivalent number of values in each array. Meaning, names are required.. and I might receive 5 of them, but I only might receive 3 birth dates, 2 favorite colors and 1 location. Every missing value will result in a nil. How does one make that kind of data structure with Ruby 1.9?

  • Find messages from certain key till certain key while being able to remove stale keys.

    - by Alfred
    My problem Let's say I add messages to some sort of datastructure: 1. "dude" 2. "where" 3. "is" 4. "my" 5. "car" Asking for messages from index[4,5] should return: "my","car". Next let's assume that after a while I would like to purge old messages because they aren't useful anymore and I want to save memory. Let's say at time x messages[1-3] became stale. I assume that it would be most efficient to just do the deletion once every x seconds. Next my datastructure should contain: 4. "my" 5. "car" My solution? I was thinking of using a concurrentskiplistset or concurrentskiplist map. Also I was thinking of deleting the old messages from inside a newSingleThreadScheduledExecutor. I would like to know how you would implement(efficiently/thread-safe) this or maybe use a library?

  • Windows Macro + Hot Key - Paste Without Formatting

    - by JasonStoltz
    Not sure if this appropriate to put as a question or not? It's sort of a scripting question I think. Just down vote me if not :p Basically, what I'm looking for is a way to push a windows hotkey and have whatever text is in the clipboard be stripped of formatting. An example of what the macro could do: I push (whatever hotkey combo here) open notepad.exe Paste to notepad from clipboard Select all text in notepad Copy/Cut all text from notepad Close notepad I'm just wondering if someone has done something like this before, or knows how it could be accomplished. I think this could be a huge time-saver for almost anyone. I find myself doing this all the time when cutting and pasting between different office applications, etc.

  • "2d Search" in Solr or how to get the best item of the multivalued field 'items'?

    - by Karussell
    The title is a bit awkward but I couldn't found a better one. My problem is as follows: I have several users stored as documents and I am storing several key-value-pairs or items (which have an id) for each document. Now, if I apply highlighting I can get the first n items. If you have several hundreds of such items this highlighting is necessary and works nicely. But there are two problems: The highlighted text won't contain the id and so retrieving additional information of the highlighted item text is ugly. E.g. you need to store the id in the text so that the highlighter returns it. Adding the id to the hl.fl parameter does not help. You will not get the most relevant n-items. You will get the first n items ... So how can I find the best items of a documents with multiple such items? I will now add my own findings as answers, but as I will point out. Each of them has its drawbacks. Hopefully anyone of you can point me to a better solution.

  • php Undefined index but i can access that key anyways

    - by Linas
    I just don't get it, i know what the error means i know how to fix it but it seems to be more of a php bug, i have an array returned from some function which looks like this when i use var_dump: array(1) { ["89512480-1884-11e2-aee6-618bca23e5b1"]=> array(5) { ["created"]=> string(10) "1350514509" ["expires"]=> string(10) "1351724109" ["token"]=> string(40) "81fa1895a6d5d4cb11efae8e71adf98fbdbfb5ca" ["user_agent"]=> string(40) "6ab18a2ea1d4b17d67713e416b07d46bf2f4d03b" ["username"]=> string(4) "test" } } array(0) { } but if i try for example: echo $token['89512480-1884-11e2-aee6-618bca23e5b1']['user_agent']; it shows me the value, but at the same time i get that annoying error, what the hell?
