• visual studio C++ toggle comment ? comment while not whole line is selected ?

  - by Mr_and_Mrs_D

  2 questions actually : 1) shortcut to toggle comment on selected lines ? Available on all iDEs I used starting with notepad++ 2)the ctrl-k, ctrl-c exhibits this behavior (quoted from someplace nicely worded): C#: Each line where some text is selected is commented at the line-start with double-slash. If nothing is selected, the line where the cursor is is commented. C++: If nothing is selected or complete lines are selected, it behaves as above. However, if parts of a line are selected, and no comment is selected as part of the selection (ex. select something in the middle of a code line), then the selection is surrounded by /* and */. since I code in C++ I find this behavior annoying - I want to be able to comment out lines partially selected - any workarounds ?

• In what package should a "Settings" class be placed?

  - by Tom

  I'm in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

• Count The Amount Of Data In An Array Including SOME Null

  - by Josephine

  I'm coding in java and I need to create a function that returns the number of Data objects that are currently in an ArrayList. At the moment I have this: int count = 0; for (int i = 0; i < data.length; i++) { if (data[i] != null) { count ++; } } return count; But the problem is that an array list that includes null data is acceptable, and I have to count their null data towards this counter. How do I include the null data that's in the middle of this array, and not the null data that's not supposed to be counted for? For example, I have some tester code that adds (8),null,null,(23),(25) to the array, and this function should return 5 when the initial array size is 10. Thank you so much

• How do I add events to nested server controls? (ASP.Net)

  - by bert

  I am building a custom master page type control i.e. sort of like a datagrid but should be easier to add custom functionality into it. It's going great but part of the desired functionality is to have a paging control that switches on and off and part of that control would be a textbox that displays the current page number and on TextChanged redirects to the new page of the dataset. The problem I'm having is that technically the textbox which has its event fired is embedded in a control that is embedded in the control you actually put on the page sort of like Page  | Display Control  | Paging Control  | Textbox Buried all the way down there the event is not firing. Worse the postback javascript isn't even being written onto the page (Nothing on the page posts back so far this is the only bit that really needs to). I've been trawling around Google for quite a while now and picked up that I need to implement INamingContainer (done) and I need to add the control into the page's control tree (is Pre_Init too late for that? When's a good time to Add the Control to the page?) then the event should fire, apparently. But I've been unable to find an example of best practice on this there are quite a few near misses where people are having button angst but this isn't a button. So can anyone point me in the direction of getting a control embedded in a control embedded in a control added to a page to behave properly?

• nested list comprehension using intermediate result

  - by KentH

  I am trying to grok the output of a function which doesn't have the courtesy of setting a result code. I can tell it failed by the "error:" string which is mixed into the stderr stream, often in the middle of a different conversion status message. I have the following list comprehension which works, but scans for the "error:" string twice. Since it is only rescanning the actual error lines, it works fine, but it annoys me I can't figure out how to use a single scan. Here's the working code: errors = [e[e.find('error:'):] for e in err.splitlines() if 'error:' in e] The obvious (and wrong) way to simplify is to save the "find" result errors = [e[i:] for i in e.find('error:') if i != -1 for e in err.splitlines()] However, I get "UnboundLocalError: local variable 'e' referenced before assignment". Blindly reversing the 'for's in the comprehension also fails. How is this done? THanks. Kent

• jQuery, Ajax & PHP submit multiple forms dilemma

  - by user557563

  This is a very simple form that I have found on the web (as I am a jQuery beginner). <!-- this is my jquery --> <script> $(document).ready(function(){ $("form#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var id = $('#id').attr('value'); $.ajax({ type: "POST", url: "index.php?leht=pildid", data:"message_wall="+ message_wall + "&id="+ id, cache: false, success: function(){ $("ul#wall").prepend(""+message_wall+"", ""+id+""); $("ul#wall li:first").fadeIn(); alert("Thank you for your comment!"); } }); return false; }); }); </script> <!-- this is my HTML+PHP --> some PHP ... while($row_pilt = mysql_fetch_assoc($select_pilt)){ print <form id="submit_wall"> <label for="message_wall">Share your message on the Wall</label> <input type="text" id="message_wall" /> <input type="hidden" id="id" value="'.(int)$row_pilt['id'].'"> <button type="submit">Post to wall</button> </form> and down below is my PHP script that writes to mySQL. It is a pretty straight forward script. However, it is getting little complicated when I submit it. Since I have more than one form on my page (per WHILE PHP LOOP), thus when I submit - only the FIRST form gets submitted. Furthermore, any other subsequent forms that I submit - data is being copied from the first form. Is there any jQuery functions that clear the data? - or is there a better solution. Thanks, Nick

• Exception handling pattern

  - by treefrog

  It is a common pattern I see where the error codes associated with an exception are stored as Static final ints. when the exception is created to be thrown, it is constructed with one of these codes along with an error message. This results in the method that is going to catch it having to look at the code and then decide on a course of action. The alternative seems to be- declare a class for EVERY exception error case Is there a middle ground ? what is the recommended method ?

• Synergy doesn't work correctly if I switch client/server role (left of works, right of does not)

  - by PhilW

  When I use my win7/64bit as a server, with the mac (10.7.5) on its left, it works. Screens: [Mac/10.7.5]---[Win7/64bit] I've now switched the roles, so I use the Mac's keyboard (because Bug #18/19) and use windows as a client. Now I cannot move the mouse over the right edge to the windows client. But if I configure windows to be on the left (virtually at least), it works, I can use the left edge to cross over to the windows client. Dock is on the bottom. Synergy v1.4.15 What do I need to change in order to fix this? Thanks!

• changes in main.xml are not reflected in the android app in netbeans

  - by nitish712

  I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps. I have written the following code in the main java file: package com.test.helloworld; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class helloworld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView t1=new TextView(this); t1.setText("hello world..!!!!"); setContentView(t1); } } This was working fine. I edited the main.xml file to display a textfield and button as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send"/> <EditText android:id="@+id/edit_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="@string/edit_message"/> </LinearLayout> Of course I have added all the corresponding strings in strings.xml. But when I try to run my app these weren't displaying... :( . I mean the same string that was displayed previously was being displayed. Can anybody figure out what is the mistake? thanx...

• is there an equivalent to a "Focus Listener" in Objective-C or iPhone SDK? (Coming from Java)

  - by MarcZero

  Hello. I am a student programmer who has taken up Objective-C on my free time as my college doesn't teach it. We have only used Java and basic C so far. I am in the middle of making a program for the iPod and was wondering if there was any type of way to call a method in a class similar to the way a Focus Listener does in Java? I have a view that I would like to call a refresh method (to update the newly inputted titles of buttons from another view) when the view is put at the top and visible again. Is this too easy or is there a more methodical way of doing that? I have tried to just call the method from the other view class but it does not seem to work (says the other class is either undefined or may not accept the method call and crashes on execution). Any insight would be appreciated. Thank you for your time.

• Tiles in Windows 8 are disappearing

  - by BetaRide

  I've just upgraded from Windows XP to Windows 8 on a Dell Latitude D820, which went fine. But, after installing a new driver for the video card, the Start Screen is not working anymore. As soon the mouse touches a tile, they all disappear and I'm left with only the background image. I can go to the desktop by hitting Win+D and if I hit the Win key after some minutes the tiles are there again only to disappear as soon the mousepointer touches them. How do I fix this?

• how to set custom tab in jquery ui and use with rails

  - by Katyal

  I'm using jqueryUI for tabs on a page. I initialize it like below: $("#tabs").tabs(); <div id="tabs"> <ul> <li><a href="#tabs-4">Part A</a></li> <li><a href="#tabs-2">Part B</a></li> <li><a href="#tabs-5">Part C</a></li> </ul> <div id="tabs-4"> ..... </div> <div id="tabs-2"> .... </div> <div id="tabs-5"> .... </div> </div> I have 2 questions. How do I set the tab to be custom. say I want second tab to be shown first. $('#tabs').tabs(2) does not work. i got that from this link Let say I click on a button inside tab1. Clicking on the button takes control back to an action and then control comes back to this page. When the control comes back...then is it possible to set a custom tab?. For example. in tab 1 I click something...go back to the action...and then I want to come back to tab 2.

• What's the story with ubuntu?

  - by A-ha

  Guys, I've tried to install ubuntu 10.10 desktop ed. on my laptop and unfortunately it didn't detect my keyboard (it detects my mouse) so I couldn't finish installation. Is it something wrong I'm doing? There isn't really much to specify during the installation process and I'm really dissapointed that such trivial task as installation cannot be done without asking a question on a forum. Or maybe just because I'm trying to install it on my laptop I shall download notebook edition? But that sound silly to me.

• Does @import in CSS result in additional http requests?

  - by Mo Boho

  I have an ecommerce site that has about 8 CSS files linked from the header - resulting in 8 separate http requests to the server. I consolidated all the CSS files into 1 big one, resulting in a 67kb (!) file - to cut down the http requests to 1 for our css files. I'm finding this size a CSS file a little unmanageable in light of the fact I'm performing updates on the site constantly. My concern is my users may catch me in the middle of updating and see a NON-styled page when moving from page to page - b/c 67kb still takes a good 2-3 seconds before it is successfully placed on the remote server via FTP. My question is: does the use of @import within this large CSS file to break up the files into smaller more manageable sizes (within that CSS file) take us back to the original 8 http-requests when the pages is loaded? Or are @imports in CSS handle differently somehow?

• Google Chrome && (cache || memory leaks).

  - by Alexey Ogarkov

  Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.

• Creating 3rd party library in Android. Need suggestions!!

  - by Lalith

  Hello all, I am planning to create a 3rd party library for android application developers. Also the main concern is I do not want the users to make many changes to their code base. The following are the main things I want to clarify before diving into the project. 1) I want to attach my own event handlers dynamically to the application. As per above limitations I mentioned, I cannot make users put the relevant code in their handlers as I need to support existing applications as well. I found out that we cannot attach more than one event handler per one listener. For example Button.setOnclickListener(somelistener) .. will set one listener. In traditional desktop applications we can add more than one handlers but here if I do one more Button.setOnclickListener(someOtherListener) this one overwrites the previous listener. Is there any way I can attach my own listener along with application's existing listeners dynamically? Also is it really not supported on android yet? 2) Is there any 3rd party alternative that exists already that monitors user's interactions in androidi? 3) If this is not supported now are there any future plans to support this feature? Please let me know about this as I did not get much feedback on Stackoverflow. Any suggestions and workarounds would really help me continue with this project. Regards, Lalith

• PHP SDK Requires two logins...doesn't recognize first

  - by Jay Konieczny

  I am using the following code to authenticate whether users are logged in or not. While users can log in, they have to click the login button twice. Additionally, sometimes even after they click the log-in button twice, my "user info" part of the page (earlier in the page than the content) shows them as logged out while the actual page shows them as logged in. Here is the code. Could someone suggest a better way of handling log-ins? function isLoggedIn($facebook) { if (isset($facebook) and $facebook->getUser() != 0) { // UserID exists, but user may still not be logged in. Let's check: try { $facebook->api('/me', 'GET'); // If this succeeds, then they are logged in. return true; } catch(FacebookApiException $e) { // Some kind of error, so not logged in. if(session_id() === '') session_destroy(); return false; } } else { if(session_id() === '') session_destroy(); return false; } } Thanks!

• .Net forms - intercepting the Close X event.

  - by Hamish Grubijan

  Hi, this must be a dumb question, but I cannot figure it out. I also cannot use the designer because coders before me managed to throw GUI and logic all in one, so now it is confused. I've got to do it the old school way. I have a Form which can be closed in 3 ways: Close button, File / Close menu, and the X icon. I want them all to do the same thing. Intercepting the button and the menu events is easy. In fact, both are hooked up to an onCloseConfig method. Btw, is there a better name for this method? private void onCloseConfig(object sender, System.EventArgs e) { if (! m_configControl.Modified) { Application.Exit(); // Or should it be this.Close(); } .... // Else present a dialog, ask if they want to save. } So, to intercept the X I tried: this.FormClosing +=new FormClosingEventHandler(this.onCloseConfig); I believe this is what causes an infinite loop. I do not want that :) FormClosed is another option, but it seems too late. I just want to intercept the fact that the X was clicked, not the fact that the form is closing. Please help. Thanks!

• Control Windows 8 with a tablet

  - by Frantumn

  It seems much of Windows 8 is based on the idea that it will be running on tablets, and touch screen PCs. I like this, but I don't have a W89 tablet, or a touch PC yet. I'm running W8 on a laptop, and am wondering if there's any way of using my iPad2 as a touch interface with metro? Or another options that'd be nice is if there's a input device similar to Apple's "Magic Trackpad" that would allow me to use hand gestures instead of a mouse cursor when in metro apps. I've seen some cool videos of MS Smart Glass and it would seem that the capabilities are there. But it may just be too early on to do this? I'm not sure.

• moving image to bounce or rotate in a circle

  - by BlueMonster

  I found this small application that i've been playing around with for the past little while. I was wondering, if i wanted to simply rotate the image in a circle? or make the entire image just bounce up and down, how would i modify this program to do so? Everything i've tried will just stretch the image - even if i do get it to move to the left or to the right. Any ideas on what i can do? Code is below public partial class Form1 : Form { private int width = 15; private int height = 15; Image pic = Image.FromFile("402.png"); private Button abort = new Button(); Thread t; public Form1() { abort.Text = "Abort"; abort.Location = new Point(190, 230); abort.Click += new EventHandler(Abort_Click); Controls.Add(abort); SetStyle(ControlStyles.DoubleBuffer| ControlStyles.AllPaintingInWmPaint| ControlStyles.UserPaint, true); t = new Thread(new ThreadStart(Run)); t.Start(); } protected void Abort_Click(object sender, EventArgs e) { t.Abort(); } protected override void OnPaint( PaintEventArgs e ) { Graphics g = e.Graphics; g.DrawImage(pic, 10, 10, width, height); base.OnPaint(e); } public void Run() { while (true) { for(int i = 0; i < 200; i++) { width += 5; Invalidate(); Thread.Sleep(30); } } } }

• Why does my Windows computer immediately turn back on after sleep/hibernate?

  - by nbolton

  After clicking sleep or hibernate in Windows 7, my computer loads for a while and then goes into sleep mode, but not 1 second later it powers back up. The event log has no errors and no warnings appear when it comes back out of sleep/hibernation. Here's my system specifications: Asus P5KPL-VM Windows 7 I believe this is all that's relevant. I've installed the latest chipset drivers, but I'm unable to update my BIOS (but this is another matter; maybe because the motherboard in the V3-P5G31 bundle is different). I've also tried turning off the "Allow this device to wake up my computer" for the network card, keyboard, and mouse -- but this makes no difference. If flashing the BIOS is the only thing that will fix this, then I will create a new question to this effect. Maybe I should change the suspend mode from S3 to S1?

• Configure different set of keyboard shortcuts for copy/paste in Photoshop (WIN)

  - by Diodeus

  Being left-handed, I use the mouse in my left hand. In most applications I use Ctrl + Insert or Shift + Insert to copy and paste (with my right hand). For some bone-headed reason, this is not supported in Photoshop, so I have to use right-click Copy sub-menus, which is a lot slower. Is there a way to configure Photoshop to use Ctrl + Insert to copy and Shift + Insert to paste? EDIT: I tried editing keyboard shortcuts, but it will not accept CTRL + INSERT as a valid entry. Is there no valid option for left-handed users?
