  • xset: unable to open display

    - by user287878
    for the longest time after about 5 minutes my screen would blank out. Now the screen will go blank after 5 minutes but then 2 seconds after that it will light up white and keep the laptop backlighting on. I didnt change any settings to my knowledge it just happened randomly after powering it on one day and has occurred since then. I wish to resort back to blanking the screen out completely since i leave this computer on all the time and its hard to sleep with a huge white light all the time. "xset dpms force off" just yeilds me ---- xset: unable to open display ""

  • getView only shows Flagged Backgrounds for drawn Views, It does not show Flagged Background when scroll to view more items on list

    - by Leoa
    I am trying to create a listview that receives a flagged list of items to indicate a status to the user. I have been able to create the flag display by using a yellow background (see image at bottom). In Theory, the flagged list can have many flagged items in it. However in my app, only the first three flagged backgrounds are shown. I believe this is because they are initially drawn to the screen. The Flagged background that are not drawn initially to the screen do not show. I'd like to know how to get the remaining flags to show in the list. ListView Recycling: The backgrounds in the listView are being recycled in getView(). This recycling goes from position 0 to position 9. I have flags that need to match at positions 13, 14 and so on. Those positions are not being displayed. listView.getCheckedItemPositions() for multiple selections: This method will not work in my case because the user will not selected the flags. The flags are coming from the server. setNotifyOnChange() and/or public virtual void SetNotifyOnChange (bool notifyOnChange): I'm not adding new data to the list, so I don't see how this method would work for my program. Does this method communicate to getview when it is recycling data? I was unable to find an answer to this in my research. public void registerDataSetObserver: This may be overkill for my problem, but is it possible to have an observer object that keeps track of the all the positions in my items list and in my flag list no matter if the view is recycled and match them on the screen? Code: package com.convention.notification.app; import java.util.Iterator; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Context; import android.graphics.Color; import android.os.Bundle; import android.text.Html; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.ViewParent; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.TextView; public class NewsRowAdapter extends ArrayAdapter<Item> { private Activity activity; private List<Item> items; private Item objBean; private int row; private List<Integer> disable; View view ; int disableView; public NewsRowAdapter(Activity act, int resource, List<Item> arrayList, List<Integer> disableList) { super(act, resource, arrayList); this.activity = act; this.row = resource; this.items = arrayList; this.disable=disableList; System.out.println("results of delete list a:"+disable.toString()); } public int getCount() { return items.size(); } public Item getItem(int position) { return items.get(position); } public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { for(int k =0;k < disable.size();k++){ if(position==disable.get(k)){ //System.out.println( "is "+position+" value of disable "+disable.get(k)); disableView=disable.get(k); //AdapterView.getItemAtPosition(position); } } return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { View view = convertView; ViewHolder holder; if (view == null) { LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); view = inflater.inflate(row, null); getItemViewType(position); long id=getItemId(position); if(position==disableView){ view.setBackgroundColor(Color.YELLOW); System.out.println(" background set to yellow at position "+position +" disableView is at "+disableView); }else{ view.setBackgroundColor(Color.WHITE); System.out.println(" background set to white at position "+position +" disableView is at "+disableView); } //ViewHolder is a custom class that gets TextViews by name: tvName, tvCity, tvBDate, tvGender, tvAge; holder = new ViewHolder(); /* setTag Sets the tag associated with this view.

  • Oracle at HR Tech: What a Difference a Year Makes

    - by Natalia Rachelson
    Last week, I had the privilege of attending the famous HR Technology Conference (HR Tech) in my new hometown of Chicago. This annual event, which draws the who of who in the world of HR technology, was by far the biggest.  It wasn't just the highest level of attendance that was mind blowing, but also the amazing quality of attendees. Kudos go to the organizers, especially Bill Kutik for pulling together such a phenomenal conference. Conference highlights included Naomi Bloom's (http://infullbloom.us) Masters Panel and Mark Hurd's General Session on the last day of the conference. Naomi managed to do the seemingly impossible -- get all of the industry heavyweights and fierce competitors to travel to Chicago for her panel. Here are the executives she hosted: Our own Steve Miranda Sanjay Poonen, President Global Solutions, SAP Stan Swete, CTO, Workday Mike Capone, VP for Product Development and CIO, ADP John Wookey, EVP, Social Applications, Salesforce.com Adam Rogers, CTO, Ultimate Software       I bet you think "WOW" when you look at these names. Just this panel by itself would have been enough of a draw for any tech conference, so Naomi and Bill really scored. TechTarget published a great review of the conference here.  And here are a few highlights from Steve. "Steve Miranda, EVP Apps Dev Oracle, said delivering software in the cloud helps vendors shape their products to customer needs more efficiently. "As vendors, we're able to improve the software faster," he said. "We can see in real time what customers are using and not using." Miranda underscored Oracle's commitment to socializing its HCM platform,and named recruiting as an area where social has had a significant impact. "We want to make social a part of the fabric, not a separate piece," he said. "Already, if you're doing recruiting without social, it probably doesn't make any sense."" Having Mark Hurd at the conference was another real treat and everyone took notice.  The Business of HR publication covered Mark's participation at HR Tech and the full article is available here. Here is what Business of HR had to say: "In truth, the story of Oracle today is a story similar to many of the current and potential customers they faced at the conference this week. Their business is changing and growing. They've dealt with acquisitions of their own and their competitors continue to nip at their heels. They are dealing with growth (and yes, they are hiring in case you're interested). They have concerns about talent as well. If Oracle feels as strongly about their products as they seem to be, they will be getting their co-president in front of a lot more groups of current and potential customers like they did at the HR Technology Conference this year. And here's hoping this is one executive who won't stop talking about the importance of talent just because he isn't at the HR tech conference anymore."

  • Synchronous Actions

    - by Dan Krasinski-Oracle
    Since the introduction of SMF, svcadm(1M) has had the ability to enable or disable a service instance and wait for that service instance to reach a final state.  With Oracle Solaris 11.2, we’ve expanded the set of administrative actions which can be invoked synchronously. Now all subcommands of svcadm(1M) have synchronous behavior. Let’s take a look at the new usage: Usage: svcadm [-v] [cmd [args ... ]] svcadm enable [-rt] [-s [-T timeout]] <service> ... enable and online service(s) svcadm disable [-t] [-s [-T timeout]] <service> ... disable and offline service(s) svcadm restart [-s [-T timeout]] <service> ... restart specified service(s) svcadm refresh [-s [-T timeout]] <service> ... re-read service configuration svcadm mark [-It] [-s [-T timeout]] <state> <service> ... set maintenance state svcadm clear [-s [-T timeout]] <service> ... clear maintenance state svcadm milestone [-d] [-s [-T timeout]] <milestone> advance to a service milestone svcadm delegate [-s] <restarter> <svc> ... delegate service to a restarter As you can see, each subcommand now has a ‘-s’ flag. That flag tells svcadm(1M) to wait for the subcommand to complete before returning. For enables, that means waiting until the instance is either ‘online’ or in the ‘maintenance’ state. For disable, the instance must reach the ‘disabled’ state. Other subcommands complete when: restart A restart is considered complete once the instance has gone offline after running the ‘stop’ method, and then has either returned to the ‘online’ state or has entered the ‘maintenance’ state. refresh If an instance is in the ‘online’ state, a refresh is considered complete once the ‘refresh’ method for the instance has finished. mark maintenance Marking an instance for maintenance completes when the instance has reached the ‘maintenance’ state. mark degraded Marking an instance as degraded completes when the instance has reached the ‘degraded’ state from the ‘online’ state. milestone A milestone transition can occur in one of two directions. Either the transition moves from a lower milestone to a higher one, or from a higher one to a lower one. When moving to a higher milestone, the transition is considered complete when the instance representing that milestone reaches the ‘online’ state. The transition to a lower milestone, on the other hand, completes only when all instances which are part of higher milestones have reached the ‘disabled’ state. That’s not the whole story. svcadm(1M) will also try to determine if the actions initiated by a particular subcommand cannot complete. Trying to enable an instance which does not have its dependencies satisfied, for example, will cause svcadm(1M) to terminate before that instance reaches the ‘online’ state. You’ll also notice the optional ‘-T’ flag which can be used in conjunction with the ‘-s’ flag. This flag sets a timeout, in seconds, after which svcadm gives up on waiting for the subcommand to complete and terminates. This is useful in many cases, but in particular when the start method for an instance has an infinite timeout but might get stuck waiting for some resource that may never become available. For the C-oriented, each of these administrative actions has a corresponding function in libscf(3SCF), with names like smf_enable_instance_synchronous(3SCF) and smf_restart_instance_synchronous(3SCF).  Take a look at smf_enable_instance_synchronous(3SCF) for details.

  • Howto make a diff of a bios or backup/ restore all bios settings

    - by sfonck
    Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

  • Mac always boots with incorrect display gamma (for years now including Lion)

    - by Alex Wayne
    I think somewhere, something got installed but I have no idea what or how to fix it :( Basically, my old MacBook Pro running 10.5 Leopard had a problem where on boot it would show everything on the screen in a very sort of crunched color space. Everything below 15% white would just be pure black, everything above 85% white would be pure white and all colors look to be a touch more saturated. It's garish. To fix it, I found that I could boot into almost any fullscreen 3D game. When the game launches, the colors would still be off, but when I then quite the game and return the desktop everything is normal again. I've noticed Blizzard games work most reliably for this (World of Warcraft or Starcraft2). This problem has followed me through the years. When I upgraded to an iMac I migrated everything over to it, and the issue now happens on the iMac too. I then got a new MacBook Pro for work and migrated my iMac over to that, and it has the problem too. I had thought that it was an OS bug, but upgrading to 10.6 Snow Leopard didn't fix it and neither did 10.7 Lion. Furthermore I can't find any reference on any forum or help site where anyone else has this problem. If anyone has any idea what processes or settings or apps I should look at to figure out why this is happening I should would appreciate it! It looks sort of irresponsible when I open my laptop in the office to work and then boot up Starcraft 2 full screen...

  • Cannot use READPAST in snapshot isolation mode

    - by Marcus
    I have a process which is called from multiple threads which does the following: Start transaction Select unit of work from work table with by finding the next row where IsProcessed=0 with hints (UPDLOCK, HOLDLOCK, READPAST) Process the unit of work (C# and SQL stored procedures) Commit the transaction The idea of this is that a thread dips into the pool for the "next" piece of work, and processes it, and the locks are there to ensure that a single piece of work is not processed twice. (the order doesn't matter). All this has been working fine for months. Until today that is, when I happened to realise that despite enabling snapshot isolation and making it the default at the database level, the actual transaction creation code was manually setting an isolation level of "ReadCommitted". I duly changed that to "Snapshot", and of course immediately received the "You can only specify the READPAST lock in the READ COMMITTED or REPEATABLE READ" error message. Oops! The main reason for locking the row was to "mark the row" in such a way that the "mark" would be removed when the transaction that applied the mark was committed and the lock seemed to be the best way to do this, since this table isn't read otherwise except by these threads. If I were to use the IsProcessed flag as the lock, then presumably I would need to do the update first, and then select the row I just updated, but I would need to employ the NOLOCK flag to know whether any other thread had set the flag on a row. All sounds a bit messy. The easiest option would be to abandon the snapshot isolation mode altogether, but the design of step #3 requires it. Any bright ideas on the best way to resolve this problem? Thanks Marcus

  • How to get the sending email address from outlook 2007

    - by Naresh
    I am working on outlook add-in project using Visual studio 2008 for MS Outlook 2007 in C#. Here I am explaining my problem... I got multiple accounts (3 Accounts) with my outlook 2007. I need to get accounts form Account box in New Mail Message window. When we click New Mail Message, a new window will appear from which we can send a new mail. Here (On this window) we can see Account Dropdown (Left side) under the Send Button. If we have multiple accounts with outlook, we can see all the accounts in Account Drop Down if we click on Account Box. If we click on the particular email, a right mark will appear to that Email Account and a message can bee seen on the top of the Send button is "This message will be sent via [email protected]". So, I want to get these email accounts into a string and that particular email account (which has right mark) into another string. I got these 3 email accounts into a string. But, I am not getting the particular email account(which has the right mark when we send a new email). I am using this code.... using Outlook = Microsoft.Office.Interop.Outlook; using Office = Microsoft.Office.Core; using Microsoft.Office.Interop.Outlook; Outlook._Application myOutlookApp = new Outlook.Application(); Outlook.Accounts myAccounts = myOutlookApp.Session.Accounts; foreach (Outlook.Account account in myAccounts) { string emailAddress = account.SmtpAddress; } I am able to get all the accounts from the above code..But, I just want to get the email address which we will use for sending an email at that particular moment..

  • mod_rewrite with question marks and ampersands (with PHP)

    - by Chris
    I have a PHP-based web app that I'm trying to apply Apache's mod_rewrite to. Original URLs are of the form: http://example.com/index.php?page=home&x=5 And I'd like to transform these into: http://example.com/home?x=5 Note that while rewriting the page name, I'm also effectively "moving" the question mark. When I try to do this, Apache happily performs this translation: RewriteRule ^/([a-z]+)\?(.+)$ /index.php?page=$1&$2 [NC,L] But it messes up the $_GET variables in PHP. For example, a call to http://example.com/home?x=88 yields only one $_GET variable (page => home). Where did x => 88 go? However, when I change my rule to use an ampersand rather than a question mark: RewriteRule ^/([a-z]+)&(.+)$ /index.php?page=$1&$2 [NC,L] a call like http://example.com/home&x=88 will work just as I'd expect it to (i.e. both the page and x $_GET variables are set appropriately). The difference is minimal I know, but I'd like my URL variables to "start" with a question mark, if it's possible. I'm sure this reflects my own misunderstanding of how mod_rewrite redirects interact with PHP, but it seems like I should be able to do this (one way or another). Thanks in advance! Cheers, -Chris

  • Algorithm To Select Most Popular Places from Database

    - by Russell C.
    We have a website that contains a database of places. For each place our users are able to take one of the follow actions which we record: VIEW - View it's profile RATING - Rate it on a scale of 1-5 stars REVIEW - Review it COMPLETED - Mark that they've been there WISH LIST - Mark that they want to go there FAVORITE - Mark that it's one of their favorites In our database table of places each place contains a count of the number of times each action above was taken as well as the average rating given by users. views ratings avg_rating completed wishlist favorite What we want to be able to do is generate lists of the top places using the above information. Ideally, we would want to be able to generate this list using a relatively simple SQL query without needing to do any legwork to calculate additional fields or stack rank places against one another. That being said, since we only have about 50,000 places we could run a nightly cron job to calculate some fields such as rankings on different categories if it would make a meaningful difference in the overall results of our top places. I'd appreciate if you could make some suggestions on how we should think about bubbling the best places to the top, which criteria we should weight more heavily, and given that information - suggest what the MySQL query would need to look like in order to select the top 10 places. One thing to note is that at this time we are less concerned with the recency of a place being popular - meaning that looking at the aggregate information is fine and that more recent data doesn't need to be weighted more heavily. Thanks in advance for your help & advice!

Verification has to happen for max N times with each T intervals for all orders. if verification successful for all the order before N retry then fine.. otherwise we need to indicate as verification unsuccessfull. i hv done a basic coding done in very urgent like below for( N times ) { for_each ( sent_request_order ) // SENT { 1) get all the refreshed order from DB or shared mem i.e REFRESHED 2) find current sent order in REFRESHED if( not_found ) not refreshed from exchange, continue to next order if( found ) case NEW : //check for new status, mark verification done case MODIFY : //check for modified status.. //if not mark pending, go to next order, //revisit the same after T time case CANCEL : //check for cancelled status.. //if not mark pending, go to next order, //revisit the same after T time } if( all_verified ) exit from verification. wait ( T sec ) } order_verification_pending, order_verification_done, order_visited, order_not_visited, all_verified, all_not_verified ... lot of boolean flags used for indication.. is there any better approach for doing this.... splitting responsibilities across the classes......???? i know this is not a general question.... but still flags are making me tidious to handle...

  • .NET Regular Expression to find actual words in text

    - by Mehdi Anis
    I am using VB .NET to write a program that will get the words from a suplied text file and count how many times each word appears. I am using this regular expression:- parser As New Regex("\w+") It gives me almost 100% correct words. Except when I have words like "Ms Word App file name is word.exe." or "is this a c# statment If(ab?1,0) ?" In such cases I get [word & exe] AND [If, a, b, 1 and 0] as seperate words. it would be nice (for my purpose) that I received word.exe and (If(ab?1,0) as words. I guess \w+ looks for white space, sentence terminating punctuation mark and other punctuation marks to determine a word. I want a similar regular Expression that will not break a word by a punctuation mark, if the punctuation mark is not the end of the word. I think end-of-word can be defined by a trailing WhiteSpace, Sentence terminating Punctuation (you may think of others). if you can suggest some regular expression 9for VB .NET) that will be great help. Thanks.

  • Git merge 2 new file with removed content and added content

    - by Loïc Faure-Lacroix
    So we are working in with 2 different repositories and both designers modified the same file. the problem is quite simple but I have no ideas how to solve it yet. Both files are marked as new since they have almost nothing in common except that file. When I try to merge from branch A to B it mark the parts added in A deleted in B and on the other side, what was added in B appears deleted in A. git seems to try to outsmart me when I know that I need almost every changes and nothing should be mark as deletion. I have 2 other branch that should merge without problem after these 2 branch. I can't merge them yet since there are some recent changes that may not merge really well too. I have to merge A and B = E then C and D = F and then hopefully E and F So the big question here is how can I do a completely manual merge that will mark every changes as conflict anything deleted anything added should be marked as conflict that I can solve by myself using an editor. Git is trying to outsmart me and fail terribly at it.

  • Converting "A* Search" code from C++ to Java [on hold]

    - by mr5
    Updated! I get this code from this site It's A* Search Algorithm(finding shortest path with heuristics) I modify most of variable names and some if conditions from the original version to satisfy my syntactic taste. It works in C++ (as I can't see any trouble with it) but fails in Java version. Java Code: String findPath(int startX, int startY, int finishX, int finishY) { @SuppressWarnings("unchecked") LinkedList<Node>[] nodeList = (LinkedList<Node>[]) new LinkedList<?>[2]; nodeList[0] = new LinkedList<Node>(); nodeList[1] = new LinkedList<Node>(); Node n0; Node m0; int nlIndex = 0; // queueList index // reset the node maps for(int y = 0;y < ROW_COUNT; ++y) { for(int x = 0;x < COL_COUNT; ++x) { close_nodes_map[y][x] = 0; open_nodes_map[y][x] = 0; } } // create the start node and push into list of open nodes n0 = new Node( startX, startY, 0, 0 ); n0.updatePriority( finishX, finishY ); nodeList[nlIndex].push( n0 ); open_nodes_map[startY][startX] = n0.getPriority(); // mark it on the open nodes map // A* search while( !nodeList[nlIndex].isEmpty() ) { LinkedList<Node> pq = nodeList[nlIndex]; // get the current node w/ the highest priority // from the list of open nodes n0 = new Node( pq.peek().getX(), pq.peek().getY(), pq.peek().getIterCount(), pq.peek().getPriority()); int x = n0.getX(); int y = n0.getY(); nodeList[nlIndex].pop(); // remove the node from the open list open_nodes_map[y][x] = 0; // mark it on the closed nodes map close_nodes_map[y][x] = 1; // quit searching when the goal state is reached //if((*n0).estimate(finishX, finishY) == 0) if( x == finishX && y == finishY ) { // generate the path from finish to start // by following the directions String path = ""; while( !( x == startX && y == startY) ) { int j = dir_map[y][x]; int c = '0' + ( j + Node.DIRECTION_COUNT / 2 ) % Node.DIRECTION_COUNT; path = (char)c + path; x += DIR_X[j]; y += DIR_Y[j]; } return path; } // generate moves (child nodes) in all possible directions for(int i = 0; i < Node.DIRECTION_COUNT; ++i) { int xdx = x + DIR_X[i]; int ydy = y + DIR_Y[i]; // boundary check if (!(xdx >= 0 && xdx < COL_COUNT && ydy >= 0 && ydy < ROW_COUNT)) continue; if ( ( gridMap.getData( ydy, xdx ) == GridMap.WALKABLE || gridMap.getData( ydy, xdx ) == GridMap.FINISH) && close_nodes_map[ydy][xdx] != 1 ) { // generate a child node m0 = new Node( xdx, ydy, n0.getIterCount(), n0.getPriority() ); m0.nextLevel( i ); m0.updatePriority( finishX, finishY ); // if it is not in the open list then add into that if( open_nodes_map[ydy][xdx] == 0 ) { open_nodes_map[ydy][xdx] = m0.getPriority(); nodeList[nlIndex].push( m0 ); // mark its parent node direction dir_map[ydy][xdx] = ( i + Node.DIRECTION_COUNT / 2 ) % Node.DIRECTION_COUNT; } else if( open_nodes_map[ydy][xdx] > m0.getPriority() ) { // update the priority info open_nodes_map[ydy][xdx] = m0.getPriority(); // update the parent direction info dir_map[ydy][xdx] = ( i + Node.DIRECTION_COUNT / 2 ) % Node.DIRECTION_COUNT; // replace the node // by emptying one queueList to the other one // except the node to be replaced will be ignored // and the new node will be pushed in instead while( !(nodeList[nlIndex].peek().getX() == xdx && nodeList[nlIndex].peek().getY() == ydy ) ) { nodeList[1 - nlIndex].push( nodeList[nlIndex].pop() ); } nodeList[nlIndex].pop(); // remove the wanted node // empty the larger size queueList to the smaller one if( nodeList[nlIndex].size() > nodeList[ 1 - nlIndex ].size() ) nlIndex = 1 - nlIndex; while( !nodeList[nlIndex].isEmpty() ) { nodeList[1 - nlIndex].push( nodeList[nlIndex].pop() ); } nlIndex = 1 - nlIndex; nodeList[nlIndex].push( m0 ); // add the better node instead } } } } return ""; // no route found } Output1: Legends . = PATH ?

= START X = FINISH 3,2,1 = OBSTACLES (Just right) From what I read about Java's documentation, I came up with the conclusion: C++'s std::queue<T>::front() == Java's LinkedList<T>.peek() Java's LinkedList<T>.pop() == C++'s std::queue<T>::front() + std::queue<T>::pop() What might I be missing in my Java version? In what way does it became different algorithmically from the C++ version?

  • how can i have a working dropdownlist with links from a csv in php

    - by Mark Dekker
    I have a website that loads a CSV, divides it into parts, and shows these parts. There are 7 parts, and since it is for a music store it is sliced like this: the name of the product the subname the price the stock in one shop the stock of the other shop the group name the brandname What i have now is that it shows 12 products on 1 page, with a next and previous link on top of the page. The pages are made with the group name, every group has it's own page, so you have a drums page, guitar page, speaker page. That all works great. What i programmed in there is a dropdownlist, it drops down a list of brandnames, which should narrow the search for a person who is looking at the products. Problem is right now, that the dropdown menu works, i see the brands, but they are NONE clickable, only the brands that are currently on the page are shown, so NOT all the brands from that group are shown, only the 12 that are currently showing, when you press next, it shows 12 more brands, but i want them to be shown right on the start. And the third problem is, when it is showing the brands, it shows them double or triple, depending on how many products have the same brand. Is there a way what i want, with this code as a basis ? <html> <body bgcolor=#E2E965 link=black vlink=black alink=black text=#D5DF23> <style type="text/css"> #nav, #nav ul { padding: 0; margin: 0; list-style: none; } #nav li { float: left; width: 120px; } #nav ul { position: absolute; width: 120px; left: -1000px; } #nav li:hover ul { left: auto; } <!-- a {text-decoration:none} //--> body { scrollbar-arrow-color: #E2E965; scrollbar-face-color: #D7182A; scrollbar-highlight-color: #000000; scrollbar-3dlight-color: #D6DF23; scrollbar-shadow-color: #00000; scrollbar-darkshadow-color: #00000; scrollbar-track-color: #D6DF23; } input:link {text-decoration: none; color: #E2E965;} input:visited {text-decoration: none; color: #E2E965;} input:active {text-decoration: none; color: #E2E965;} .spacer_black { margin: 0px; padding: 0px; border: 5px; height: 2px; width: 100%; line-height: 0px; font-size: 0px; background-color: #000000;} </style> <table width=800 border=0><td> </html> <?PHP $offset = isset($_GET['offset'])?$_GET['offset']:0; $LinesToDisplay = 12; $row = $offset + $LinesToDisplay; $row2 = $offset - $LinesToDisplay; $file_handle = fopen("web.txt", "rb"); error_reporting( E_ALL ); // DEBUGGING $SelectArray=array(); while ((($parts = fgetcsv($file_handle,4096,"|")) !== FALSE) && ($LinesToDisplay > 0) && (!feof($file_handle))) { //new code //skip first $offset lines $num = count($parts[6]); $SelectArray[]=$parts[6]; if ($parts[5] == 9999) { if ($offset-- > 0) {continue;} $parts[0] = ucwords(strtolower($parts[0])); $parts[1] = ucwords(strtolower($parts[1])); ?> <td> <?php echo "<table BACKGROUND='background.jpg' border=0 width=250><td width='243' height='105'>"; echo "<font size=-1 face='helvetica' color=#812990><b>$parts[0]</b></font>"; echo "<i>"; ?> <html> <div onMouseOver="this.style.color = 'black';" onMouseOut="this.style.color = '#D5DF23';"> </html><?php echo "<font size=2>-$parts[1]</font>"; echo "</div></i>"; ?><html><a href="#" title="Koop nu de <?php echo $parts[0]; ?>" onClick="window.open('form.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div><img src='ster.jpg' border=0 width='46' align='right'></a> <a href="#"><img src='envelope.jpg' border=0 width='46' align='right'title="Heeft u een vraag over <?php echo $parts[0]; ?>" onClick="window.open('vraag.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div></a> <TABLE BORDER='0' cellpadding='0' CELLSPACING='0'> <TR> <TD WIDTH='70' HEIGHT='20' BACKGROUND='pricebackground.jpg' VALIGN='bottom'> <center> <font size=2 color=white face='helvetica'> <b></html> <?php echo "€ $parts[2]"; ?> </b> </td> </tr> </table> <?php echo "<b><font size=3 color=#D7182A>Op Voorraad In:<br></font>"; echo ("<font color=black> Amsterdam </font>"); if ( $parts[3] >= 1 ) echo ("<IMG SRC =green.gif>").""; if ( $parts[3] <= 0 ) echo ("<IMG SRC =red.gif>").""; echo ("<font color=black> Utrecht </font>"); if ( $parts[4] >= 1 ) echo ("<IMG SRC =green.gif>")."</td></table></b><p style='margin:9px;'>"; if ( $parts[4] <= 0 ) echo ("<IMG SRC =red.gif>")."</td></table></b><p style='margin:9px;'>"; $LinesToDisplay--; if ($LinesToDisplay/3==intval($LinesToDisplay/3)) { echo "<tr><td>"; } }} fclose($file_handle); ?> <tr align=right> <select style="background-color: #FFFFFF; color: #000000; font-family: Arial; font-weight: none; font-size: 12; width: 150px; "> <?php $i=1; foreach ($SelectArray as $val){ echo "<option value=\"$i\">$val</option>\n"; $i++; } ?> </select> <font color=black><body alink=black vlink=black link=black text=black> <center><a href="occasiona.php?offset=<?php echo $row2; ?>" align=center>&laquo; previous</a> || <a href="occasiona.php?offset=<?php echo $row; ?>">next &raquo;</a></table></html>

  • JFace ApplicationWindow: createContents isn't working

    - by jasonh
    I'm attempting to create a window that is divided into three parts. A non-resizable header and footer and then a content area that expands to fill the remaining area in the window. To get started, I created the following class: public class MyWindow extends ApplicationWindow { Color white; Font mainFont; Font headerFont; public MyWindow() { super(null); } protected Control createContents(Composite parent) { Display currentDisplay = Display.getCurrent(); white = new Color(currentDisplay, 255, 255, 255); mainFont = new Font(currentDisplay, "Tahoma", 8, 0); headerFont = new Font(currentDisplay, "Tahoma", 16, 0); // Main layout Composites and overall FillLayout Composite container = new Composite(parent, SWT.NO_RADIO_GROUP); Composite header = new Composite(container, SWT.NO_RADIO_GROUP); Composite mainContents = new Composite(container, SWT.NO_RADIO_GROUP);; Composite footer = new Composite(container, SWT.NO_RADIO_GROUP);; FillLayout containerLayout = new FillLayout(SWT.VERTICAL); container.setLayout(containerLayout); // Header Label headerLabel = new Label(header, SWT.LEFT); headerLabel.setText("Header"); headerLabel.setFont(headerFont); // Main contents Label contentsLabel = new Label(mainContents, SWT.CENTER); contentsLabel.setText("Main Content Here"); contentsLabel.setFont(mainFont); // Footer Label footerLabel = new Label(footer, SWT.CENTER); footerLabel.setText("Footer Here"); footerLabel.setFont(mainFont); return container; } public void dispose() { cleanUp(); } @Override protected void finalize() throws Throwable { cleanUp(); super.finalize(); } private void cleanUp() { if (headerFont != null) { headerFont.dispose(); } if (mainFont != null) { mainFont.dispose(); } if (white != null) { white.dispose(); } } } And this results in an empty window when I run it like this: public static void main(String[] args) { MyWindow myWindow = new MyWindow(); myWindow.setBlockOnOpen(true); myWindow.open(); Display.getCurrent().dispose(); } What am I doing wrong that I don't see three labels the way I'm trying to display them? The createContents code is definitely being called, I can step through it in Eclipse in debug mode.
