  • Change Image with transition effects

    - by Goro
    Hello, I have the following script that changes my image on a timer: var da = setInterval( function() { var current_image = document.getElementById('node_picture').src; var image_index = current_image.substring(48,49); image_index++; if (image_index > 4) { image_index = 1; } document.getElementById('node_picture').src="img/node/<?php echo $node_id ?>/" + image_index + ".png"; }, 4000); I am trying to add a jQuery FadeIn() effect. I tried to add $('node_picture').FadeIn(); but that does not work. Thanks,

  • Changing the Default View Engine's view search behavior.

    - by bradhe
    I'm working with ASP.NET MVC 2. I have a bunch of partial views that I render based on different conditions within the same controller. I'd like to not put the physical partial view files in with the controller's other views. I know that when I want a ViewResult using the View() or PartialView() methods the default view engine will search through the folder in the Views directory associated with the controller (i.e. if my controller is called Register it will look in the Register folder under Views) and also in the Shared folder. Is there any way to change this behavior, or perhaps tell it specifically where to look for the view -- heck, even give it a specific file to render? Is that possible? Perhaps even a sub-folder under the Shared folder will work...

  • UIButton's Custom image and frame

    - by Joo Park
    I have the following code. UIImage *cancelImg = [UIImage imageNamed:@"cancel.jpeg"]; UIButton *btnCancel = [UIButton buttonWithType:UIButtonTypeCustom]; btnCancel.userInteractionEnabled = YES; [btnCancel setFrame:CGRectMake(0.0,0.0, 28.0, 28.0)]; [btnCancel setImage:cancelImg forState:UIControlStateNormal]; cell.accessoryView = btnCancel; cancel.jpeg currently is bigger than 28 x 28 and it's actually 100 x 100. Why does the button display 100 x 100 size of the image when I've set the UIButton's size to 28 x 28?

  • Using LINQ to search a byte array for all subarrays that start/stop with certain byte

    - by Joel B
    I'm dealing with a COM port application and we have a defined variable-length packet structure that I'm talking to a micro-controller with. The packet has delimiters for the start and stop bytes. The trouble is that sometimes the read buffer can contain extraneous characters. It seems like I'll always get the whole packet, just some extra chatter before/after the actual data. So I have a buffer that I append data to whenever new data is received from the COM port. What is the best way to search this buffer for any possible occurrences of my packet? For example: Say my packet delimiter is 0xFF and I have an array as such { 0x00, 0xFF, 0x02, 0xDA, 0xFF, 0x55, 0xFF, 0x04 } How can I create a function/LINQ-statment that returns all subarrays that start and end with the delimiter (almost like a sliding-correlator with wildcards)? The sample would return the following 3 arrays: {0xFF, 0x02, 0xDA, 0xFF}, {0xFF, 0x55, 0xFF}, and {0xFF, 0x02, 0xDA, 0xFF, 0x55, 0xFF}

  • binary search and trio

    - by user121196
    given a large list of alphabetically sorted words in a file,I need to write a program that, given a word x, determines if x is in the list. priorties: 1. speed. 2. memory I already know I can use (n is number of words, m is average length of the words) 1. a tri, time is O(log(n)), space(best case) is O(log(n*m)), space(worst case) is O(n*m). 2. load the complete list into memory, then binary search, time is O(log(n)), space is O(n*m) I'm not sure about the complexity on tri, please correct me if they are wrong. Also are there other good approaches?

  • PHP - ldap_search() filter. How to search for user

    - by cvack
    $_SERVER['REMOTE_USER'] returns the username of the user logged in to an Active Directory. I want to retrive this users info by using ldap_search(). This is what I have now: $ad = // ldap_connection id $filter = "(|(sn=$username*)(givenname=$username*))"; $attr = array("displayname", "mail", "mobile", "homephone", "telephonenumber", "streetaddress", "postalcode", "physicaldeliveryofficename", "l"); $dn = // OU, DC etc.. ldap_search($ad,$dn,$filter,$attr); It works, but i'm not sure it will work if two users have almost the same names. How do I only search for their unique username so that i always only get one user?

  • Creating a QLineEdit search field for items displayed in a QListView

    - by krunk
    I want to create a search field that filters the items shown in a QListView. Basically the user could type in "foo" and only items with "foo" in the DisplayRole are shown. I already have a few ideas on how to do this, but thought I'd ask those more experienced than I. My idea would be to use some signals and slots to set a filter in the QAbstractItem model and trigger an update() in the QListView. Are there any helper methods in QListView for filtering I may have missed? Is there a canonical way of handling this I haven't run across?

  • Creating an image from webcam every x miliseconds

    - by Rita
    Hello everyone, I am using c# to integrate with a web cam. I need to generate a snapshot image every x miliseconds and save it to file. I already have the code up and running to save to file on a button click event, however I wonder what am I supposed to do when taking snapshots in the background - Should this be multi threaded? I'm honestly not sure. I could just block the UI thread, put Thread.Sleep and then just take the snapshot, but I don't know if this is right. I thought of using a background worker, but I am now experiencing cross threaded difficulties with SendMessage... So I wonder if I should even go and bother to multi-thread or just block the UI. Help greatly appertained, thanks in advance.

  • Android Image Getter for Larger Images

    - by y ramesh rao
    I have used all the Standard Network related code for Getting Images of about 45KB to 75KB but all are failing these methods work fine for Files of about 3-5KB size of Images. How can I achieve Downloading Image of 45 - 75KB for displaying them on an ImageView in Android for my Netowrk Operations the Things I have used are final URL url = new URL(urlString); final URLConnection conn = url.openConnection(); HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(true); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); and the Second option that I have had used is:: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet getRequest = new HttpGet(urlString); HttpResponse response = httpClient.execute(getRequest); why is this code functional for Smaller Sized Images and not for Larger Size Images. ?

  • ImageView doesn't rescale Image to selected size

    - by Buni
    I'm using a ImageView with a fixed size for adding an icon to a menu. In my application, I use it a lot of times, but on this ImageView the Layout Params seem to not work. Unlike the others ImageViews, in this case, I'm using a template directly, but I think that's not the problem. <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="1dp" android:layout_height="1dp" android:scaleType="fitCenter" android:src="@drawable/ic_menu_moreoverflow_normal_holo_dark" android:contentDescription="ICON" /> Its been used in code as follows. ImageView iview =(ImageView) View.inflate(context, R.layout.icon, null); Theoretically, It should resize automatically the image, however, the images continues with the original size, although the size was 1dp. Where is the problem? Thanks a lot!

  • Binary Search Tree node removal

    - by doc
    I've been trying to implement a delete function for a Binary Search Tree but haven't been able to get it to work in all cases. This is my latest attempt: if(t->get_left() == empty) *t = *t->get_left(); else if(t->get_right() == empty) *t = *t->get_right(); else if((t->get_left() != empty) && (t->get_right() != empty)) { Node* node = new Node(t->get_data(), t->get_parent(), t->get_colour(), t->get_left(), t->get_right()); *t = *node; } t is a node and empty is just a node with nothing in it. I'm just trying to swap the values but I'm getting a runtime error. Any ideas? Thanks

  • Default content editor in list form doesn't allow image alignment

    - by Ben Collins
    I need to be able to adjust the alignment of an image in an "Enhanced Rich Text Field" in an announcements list in MOSS 2007. However, the default content editor in the edit form for the list doesn't provide a way to do that. What's the fastest way for me to make sure users can align images? My first thought was to customize the DispForm.aspx and EditForm.aspx pages, but they just have the ListForm web part in the content region and as far as I know, you can't customize the ListForm web part from the designer.

  • Directional Map Search

    - by Rooneyl
    Hello, I am trying so write a bit of code that will search for a given point on a map, but in a given arc of a compass bearing. e.g. 45 degress (north-east), 20 degrees either side. So far I have got a SQL command that will give me the results in a given radius, need some help on how to filter it to a direction. SELECT * FROM (SELECT `place1_id`, `place2_id`, ( 6371 * acos( cos( radians(search_latitude) ) * cos( radians( `location_lat` ) ) * cos( radians( `location_long` ) - radians(search_longitude) ) + sin( radians(search_latitude) ) * sin( radians( `location_lat` ) ) ) ) AS `distance` FROM `place` ORDER BY distance) AS `places` WHERE `places`.`distance` < search_radius AND `places`.`place2_id` = ? Will I be able to do this (if possible) all in SQL, or will it need a bit of PHP applying to it? Any and all help much appreciated!

  • Error including image in Latex

    - by euphoria83
    I am getting the following error while compiling my Latex File : ! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox). Why do I get this error ? What has this to do with an .eps file ? Infact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which as all these error that prevent it from compiling. I am using the following syntax for including the images : \begin{figure}[!h] \begin{center} \scalebox{0.45}{ \includegraphics{tree.jpg}} \end{center} \caption{\small A sample} \label{tree} \end{figure} What should I do ? Could it be that their server is using an old compiler ? UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

  • image with json and iphone

    - by alecnash
    Hi, I've got some images saved inside a db in a server and want to use them for my iphone. I created a php file so I can access them with json, got some questions though. I save all the text data from the db to a nsdictonary and it works fine. For the images should I use nsdata? Should I write a new php file for getting the image or is one enough because I am using an array to store my objects and then I use json_encode($arr) for json. Is it ok to store data to an array or is everything gonna crash?
