  • 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.

  • open program once with multiple files as arguments from explorer

    - by Jonathan
    I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance.

  • How do you know how much space an NSString (using default font) will occupy on a UITableView section

    - by paul_sns
    Basically I want to copy the behavior in iPhone's Calendar where the day of week (Mon, Tue, Wed) is on the left side of the table's section header (left justified) while the formatted date (Apr 1, 2010, May 1, 2010) based on locale is on the right side of the table's section header (right justified). I was thinking of inserting a variable amount of space in between the day of week and formatted date but I first need to know the actual space consumed by the text on both sides to figure out how much space to add. Hope to hear your thoughts on this. Thanks.

  • Div smart width

    - by Mark
    see fiddle html <div class="e" style="left:5px;top:5px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbb</div> <div class="e" style="left:5px;top:100px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>? css .e { font-size: 10px; font-family: arial; background-color: yellow; position: absolute; max-width: 300px; } you will notice the 2nd div fits the size of the content exactly, but on the first div there's a bunch of empty space to the right of the a's and b's. This is because the div hit its max width of 300px and then wrapped the b's to a 2nd line. The wrapping is good, but then I would expect the div to then shrink back down to the width of the a's so that there's no empty space to the right. Is it possible to get it to do this? Tested in Chrome and FF.

  • 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...

  • 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.

  • Children going out of parent element

  • OpenGL ES perspective projection

    - by TimeManx
    I'm having a hard time understanding how glFrustum & gluPerspective work. I understand the concept of perspective projection but the functions aren't behaving how I expect them to. For example, if I set the frustum this way glFrustumf(0, 10, 0, 10, 1, 100) and have a rectangle at points 0, 0, 1, 0, 10, 1, 10, 10, 1, 10, 0, 1 then the rectangle is drawn with its left edge at -5 & right edge at 5, so the left half of the rectangle isn't visible. And if x is translated, I'd expect y to be too. But that doesn't happen either. In whatever examples I've seen, the coordinates for the projection matrix are taken as glFrustumf(-10, 10, -10, 10, 1, 100) but either way, whatever part is shown should be dependent on the rectangle's coordinates, right?

  • replay in django + apcahce + mod_wsgi ??

    - by Adam
    I have a simple django page that has a counter on it. I use Apache2 and mod_wsgi to serve it. First, when I enter this page, the counter shows 0, as it should. The second time when I enter the page the counter shows 1 - again, it is the right behavior. The problem begins now, cause when I enter this page the third time, I get 0 again. When I refresh it goes between 0, and 1, clearly using some cache or so. If I wait for some time and then try again, it will show 2, and 3, but will be stuck with those values, till this cache or whatever it is will be flushed, and then the counter continues. Does somebody knows how I can get it work right (the real scenario deals with getting data from the DB, but the problems with this strange cache are the same). BTW, I don't have any caching engine set in my django settings.

  • .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.

  • Conversion of Single to two UInt16 values in .net

    - by Gio
    In the good old days of C. I could cast a float to an int (assuming 32 bit system), do some bit manipluation ( bitwise and, right shift, ect ), and get the upper and lower 16 bit hex representations of the floating point number, which I could then store in two short values. I'm not seeing an easy way of doing this in C#. System.Convert.ToUInt16 just does a float to int convert (even after I shift right), which leaves a vlaue of 0 if the float is less than 0, which is not the desired effect. //useless leaves me witg a value 0f 0 UIN16 s1 = (UInt16)((System.Convert.ToUInt32(d2) & 0xffff0000) >> 16); //capture the high word UInt16 s2 = (UInt16)(System.Convert.ToUInt32(d2) & 0xffff); //capture the low word A basic cast (UInt32) doesn't work either.

  • Can I dynamically adjust the height of a css set div border?

    - by Jeff
    Ok so I have a div that contains a few forms that have dynamically generated content. There are categories, that if you click on, slide/toggle down to reveal that categories sub-contents, or projects. Right now, I have it setup so that if the height of the div expands to exceed a set amount, a scroll bar shows up at the side, and the user can scroll down and see the content. NOW I am being asked to get rid of the scroll bar, and just have the div's border (which is just 1px set in the css) height adjust dynamically with the height of the div's content...can I even do that? Is there some sort of jquery animation that would allow that? A point in the right direction would be greatly appreciated!! Thanks

  • 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!

  • 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?

  • 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

  • jQuery: How to determine which <li> tag was clicked?

    - by user337909
    I am creating a form with 5 lines of text, and each text I am allowing the user to select if they want the text to be centered, left, or right justified. I have a unnumbered list with list elements x5. <li><img src="images/justify_left.png" alt="left" /><span>Justify Left</span></li> <li><img src="images/justify_center.png" alt="center" /><span>Justify Left</span></li> <li><img src="images/justify_right.png" alt="right" /><span>Justify Left</span></li> Each of the 5 set of <li> items refers to its respective line. With jQuery, how would I go about determining which of the 15 <li> items did the user select so that I can correspond the proper justification as a post method?

  • 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); } } } }

  • How do I grab hold of a pop-up that is opened from a frame?

    - by KLA
    I am testing a website using WatiN. On one of the pages I get a "report" in an Iframe, within this I frame there is a link to download and save the report. But since the only way to get to the link is to use frame.Link(...) the pop-up closes immediately after opening; Code snippet below //Click the create graph button ie.Button(Find.ById("ctl00_ctl00_ContentPlaceHolder1_TopBoxContentPlaceHolder_btnCreateGraph")).Click(); //Lets export the data ie.Div(Find.ById("colorbox")); ie.Div(Find.ById("cboxContent")); ie.Div(Find.ById("cboxLoadedContent")); Thread.Sleep(1000);//Used to cover performance issues Frame frame = ie.Frame(Find.ByName(frameNameRegex)); for (int Count = 0; Count < 10000000; Count++) {double nothing = (Count/12); }//Do nothing I just need a short pause //SelectList waits for a postback which does not occur. try { frame.SelectList(Find.ById("rvReport_ctl01_ctl05_ctl00")).SelectByValue("Excel"); } catch (Exception) { //Do nothing } //Now click export frame.Link(Find.ById("rvReport_ctl01_ctl05_ctl01")).ClickNoWait(); IE ieNewBrowserWindow = IE.AttachTo<IE>(Find.ByUrl(urlRegex)); fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(150); fileDownloadHandler.WaitUntilDownloadCompleted(200); I have tried using ie instead of frame which is why all those ie.Div's are present. if I use frame the pop-up window opens and closes instantly. If I use ie I get a link not found error. If I click on the link manually, while the test is "trying to find the link" the file will download correctly.

  • Corona SDK - Make a character pass through a platform

    - by Andy Res
    I'm building a game that has a character which should jump up on multiple platforms. The jumping functionality is done, but I would like if the character is just below a platform (static body), when I press the "jump" button, the character should pass through that platform and then sit on it. Right now it collides with the platform, and character cannot jump on it. Do you have any idea how this can be achieved? Right now the platforms are represented by rectangles with "static" body type: local platform = display.newRect( 50, 280, 150, 10 ) platform:setFillColor ( 55, 55, 55) physics.addBody ( platform, "static", {density=1.0, friction=1.0, bounce=0 }) And I was thinking if I could change, or remove the body type of platform when the character collids with it, so he can pass trough platform, but I don't know how to do this, or in general if this will work... maybe there are some built in techniques on how to achieve the effect I want?
