  • What happened to 'Copy Public Gallery Link' for folders in Photos in Dropbox?

    - by Transgenic
    I've been trying to figure out how to use the 'Photos' folder properly, but it does not seem to contain the functionality that is mentioned on various websites. From what I've read, you are supposed to create a folder within the 'Photos' folder. At that point, it becomes a public gallery for which you can access the context menu item Copy Public Gallery Link. However, I do not have this context menu item. I found a topic on the DropBox forum, but it is 2 years old. Even the various website information mentioned is over a year old. I found a topic from this year on SuperUser that mentions about the Share link menu item. I understand that this functionality is basically the same as Copy Public Gallery Link, however, the key difference is that it opens the website for which I need to click 'Copy link to this page' link, which then adds it to the clipboard. My primary questions are: Did they phase out the Copy Public Gallery Link from the context menu entirely? If not, is there a way to re-enable this menu item? If not, am I using the Photos folder properly? Lastly, if there is no way to get this menu item, is there some kind of script or hack-around that will let me simplify the Shark link + Copy link to this page functionality without requiring it to open my web browser? Note: I had to edit my post to remove other website links that I mention since I'm considered a 'New User' here and am only able to post 2 hyperlinks. Sorry.

  • How to copy or sync music on iphone 3gs on ubuntu 14.04?

    - by user276842
    I’m using Ubuntu 14.04 and want to copy music to/on my iPhone 3gs. I already installed the actual mobile device, but neither Rhythmbox nor gmusicbrowser show my phone. Only on Gigolo I can see it, and transfer data, but the music I copy is not working on my phone. On Amarok I get at least this information: termined mount-point path to /tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664 calling `ifuse "-u" "882ba1378fe4eb76e98ad6582dcad031c2247664" "-ofsname=afc://882ba1378fe4eb76e98ad6582dcad031c2247664" "/tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664"` with timeout of 10s command failed to start within timeout Failed to mount iPhone on /tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664 Does anyone have an idea?

  • RPGMakerVX - Changing item_max?

    - by rackemup420
    I've been working on a game for awhile and I am developing it with RPG Maker VX. I came to a point where I needed to... I guess for lack of better explanation... Limit the key items to just 1. So I started looking through my scripts and found (in Game_Party): #-------------------------------------------------------------------------- # * Get Maximum Number of Items Possessed #-------------------------------------------------------------------------- def max_item_number(item) return 99 end and added below it: #-------------------------------------------------------------------------- # * Get Maximum Number of Key Items Possessed #-------------------------------------------------------------------------- def max_key_item_number(item) return 1 end and right below that is: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) item_number(item) >= max_item_number(item) end So I changed the last one too: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) if key_item? == true item_number(item) >= max_key_item_number(item) end if key_item? == false item_number(item) >= max_item_number(item) end end Now this seemed to not affect anything (that I could tell). I tested it and its still the same as before I touched anything. I am new to developing games and relatively new to scripting for them. Is this approach even close to what I want to do? Any help is greatly apprecieated!

  • Replacing innertext of XML node using PHP DOMDocument

    - by Rohan Kumar
    I want to replace innertext of a XML node my XML file named test.xml is <?xml version="1.0" encoding="utf-8"?> <ads> <loop>no</loop> <item> <description>Description 1</description> </item> <item> <description>Text in item2</description> </item> <item> <description>Let play with this XML</description> </item> </ads> I want to change the value of loop and description tag both, and it should be saved in test.xml like: <?xml version="1.0" encoding="utf-8"?> <ads> <loop>yes</loop> <item> <description>Description Changing Here</description> </item> <item> <description>Changing text in item2</description> </item> <item> <description>We will play later</description> </item> </ads> I tried code in PHP: <? $file = "test.xml"; $fp = fopen($file, "rb") or die("cannot open file"); $str = fread($fp, filesize($file)); $dom=new DOMDocument(); $dom->formatOutput = true; $dom->preserveWhiteSpace = false; $dom->loadXML($str) or die("Error"); //$dom->load("items.xml"); $root=$dom->documentElement; // This can differ (I am not sure, it can be only documentElement or documentElement->firstChild or only firstChild) $loop=$root->getElementsByTagName('loop')->item(0);//->textContent; //echo $loop; if(trim($loop->textContent)=='no') { echo 'ok'; $root->getElementsByTagName('loop')->item(0)->nodeValue ='yes'; } echo "<xmp>NEW:\n". $dom->saveXML() ."</xmp>"; ?> I tried only for loop tag.I don't know how to replace nodevalue in description tag. When I run this page it shows output like: ok NEW: <?xml version="1.0" encoding="utf-8"?> <ads> <loop>yes</loop> <item> <description>Description 1</description> </item> <item> <description>Changing text in item2</description> </item> <item> <description>Let play with this XML</description> </item> </ads> It gives the value yes in browser but don't save it in test.xml any reason?

  • Simple Form validation failing Backbone

    - by Corey Buchillon
    Im not exactly adept at coding so Im probably missing something, but my view here is failing to refuse submission when one or both of the fields are empty. I have a feeling something isnt connected right to my template for the row and the view of the form Form = Backbone.View.extend({ //form vie el: '.item-form', initialize: function(){ }, events: { 'click #additem': 'addModel' }, addModel: function(itemName, price){ // simple validation before adding to collection if (itemName !="" && price !="" ){ var item = new Item({ itemName: this.$("#item").val(), price: this.$("#price").val()}); items.add(item); $("#message").html("Please wait; the task is being added."); item.save(null, {success: function (item, response,options) { item.id= item.attributes._id.$id; item.attributes.id = item.attributes._id.$id; new ItemsView({collection: items}); $("#message").html(""); } }); this.$("#item").val(''); this.$("#price").val(''); } else { alert('Please fill in both fields'); } } }); and HTML <table class="itemTable"> <thead> <tr> <th>Item</th> <th>Price</th> <th></th> </tr> </thead> <tbody class="tableBody"> <script type="text/template" id="table-row"> <td><%= itemName %></td> <td><%= price %></td> <td><button class="complete">Complete</button> <button class="remove">Remove</button></td> </script> </tbody> </table> <form class="item-form"> <input type="text" name="item" id="item" placeholder="Item"/> <!-- goes to itemName in the template for the body --> <input type="text" name="price" id="price" placeholder="Price" /><!--goes to price in the template for the body --> <button type="button" id="additem">Add</button> </form> <div id="message"></div>

  • A few problems with Delphi involving Mail Merge, SQL + Databases.

    - by Daniel
    My first problem is with mail merge. I have created a a Data File and a table, yet I am not able to fill my table with information from my Data File. The << just seems to be inserted after wherever the cursor is on the page, which is not where the table is. All that is entered into the actual table is a '59'. Therefore I think I either need to to change the code or be able to move the cursor. Here is the code I am currently using: wrdDoc.Tables.Add(wrdSelection.Range, ADOTable1.FieldCount, 3); wrdDoc.Tables.Item(1).Columns.Item(1).SetWidth(51,wdAdjustNone); wrdDoc.Tables.Item(1).Columns.Item(2).SetWidth(20,wdAdjustNone); wrdDoc.Tables.Item(1).Columns.Item(3).SetWidth(100,wdAdjustNone); // Set the shading on the first row to light gray wrdDoc.Tables.Item(1).Rows.Item(1).Cells .Shading.BackgroundPatternColorIndex := wdGray25; // BOLD the first row wrdDoc.Tables.Item(1).Rows.Item(1).Range.Bold := True; // Center the text in Cell (1,1) wrdDoc.Tables.Item(1).Cell(1,1).Range.Paragraphs.Alignment := wdAlignParagraphCenter; // Fill each row of the table with data wrdDoc.Tables.Item(1).Cell(1, 1).Range.InsertAfter('Time'); wrdDoc.Tables.Item(1).Cell(1, 2).Range.InsertAfter(''); wrdDoc.Tables.Item(1).Cell(1, 3).Range.InsertAfter('Teacher'); For Count := 1 to (ADOTable1.FieldCount - 1) do begin wrdDoc.Tables.Item(1).Cell((Count + 1), 1).Range.InsertAfter(wrdSelection.Range,'Time' + IntToStr(Count)); wrdDoc.Tables.Item(1).Cell((Count + 1), 2).Range.InsertAfter(wrdSelection.Range,'THonorific' + IntToStr(Count)); wrdDoc.Tables.Item(1).Cell((Count + 1), 3).Range.InsertAfter(wrdSelection.Range,'TSurname' + IntToStr(Count)); end; My second problem is that I do not know what the correct SQL syntax is for editing the name of a column in the database (I am using Delphi 7 and Microsoft Jet Engine if that makes a difference). The third problem is that when I add a new column to my database manually (which I need to do) I get a 'violation' error in one of my units when I activate an ADOTable. This only happens on one unit and it happens when I add a column with any name anywhere in the table. I know that is vague but I can't seem to narrow down the problem any further than that. If you could help with me with any of those it would be great. Thanks.

  • Android application transparency and window sizing at root level

    - by ajoburg
    Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the transparency and window sizing is done with activities that are not the root task and this works fine. However, the root task of an activity seems to always fill the whole screen and be black even when a transparent theme is applied to the application object in the manifest file. ApplicationManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:theme="@style/Theme.Transparent"> Styles.xml <resources> <style name="Theme.Transparent"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@drawable/ transparent_background</item> <item name="android:windowAnimationStyle">@android:style/ Animation.Translucent</item> <item name="android:colorForeground">#fff</item> <item name="android:windowIsFloating">true</item> <item name="android:gravity">bottom</item> </style> </resources> Colors.xml <resources> <drawable name="transparent_background">#00000000</drawable> </resources>

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Asp.Net Cache, modify an object from cache and it changes the cached value

    - by Glen
    Hi, I'm having an issue when using the Asp.Net Cache functionality. I add an object to the Cache then at another time I get that object from the Cache, modify one of it's properties then save the changes to the database. But, the next time I get the object from Cache it contains the changed values. So, when I modify the object it modifies the version which is contained in cache even though I haven't updated it in the Cache specifically. Does anyone know how I can get an object from the Cache which doesn't reference the cached version? i.e. Step 1: Item item = new Item(); item.Title = "Test"; Cache.Insert("Test", item, null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration); Step 2: Item item = (Item)Cache.Get("test"); item.Title = "Test 1"; Step 3: Item item = (Item)Cache.Get("test"); if(item.Title == "Test 1"){ Response.Write("Object has been changed in the Cache."); } I realise that with the above example it would make sense that any changes to the item get reflected in cache but my situation is a bit more complicated and I definitely don't want this to happen.

  • XSL: List divided into columns.

    - by kalininew
    Hello, help me please. There is a list of nodes. <list> <item>1</item> <item>2</item> <item>3</item> <item>4</item> <item>5</item> <item>6</item> <item>7</item> and so on... </list> Need to divide the list of "n" (arbitrary number) equal parts. If the number of nodes is not divided equally, then let the last set of nodes will contain the remainder of the division. For example, if the input list contains 33 elements and the output should have 4 parts with uniformly distributed elements. At the exit to get 3 parts to 9 of elements and one part with 6 elements in the sum of 33.

  • Button style in AlertDialogs

    - by Steve H
    Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for themes and styles and experimented with different things but I haven't been able to find a way that works. What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. myTheme is applied to the whole <application> via the manifest. (Some other items were deleted for clarity, but they only relate to the title bar.) <style name="myTheme" parent="android:Theme"> <item name="android:buttonStyle">@style/customButtonStyle</item> <item name="android:alertDialogStyle">@style/dialogAlertTheme</item> </style> <style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert"> <item name="android:fullDark">@drawable/dialog_loading_background</item> <item name="android:topDark">@drawable/dialog_alert_top</item> <item name="android:centerDark">@drawable/dialog_alert_center</item> <item name="android:bottomDark">@drawable/dialog_alert_bottom</item> <!-- this last line makes no difference to the buttons --> <item name="android:buttonStyle">@style/customButtonStyle</item> </style> Any ideas?

  • How to change tab background on viewpagerindicator tabs?

    - by user1736277
    I am using ViewpagerIndicator library by Jake Wharton. I am using the tabs code in conjunction with the ActionBarSherlock library. Everything works fine, but I'm trying to style the background of the tabs and can't figure out how. I would like a dark action bar with dark tabs and light fragments (tab content). The base theme I am using is Theme.Sherlock.Light.DarkActionBar. I extend this style by making it the parent of a style that sets attributes for the tabs (like text color, indicator color, etc). This results in dark actionbar, light tabs, and light fragments. I can't find anything that will change the background of the tabs themselves. The only way I can change it is by changing the whole app to dark (using Theme.Sherlock). Here's my code so far: <style name="vpiTheme" parent="Theme.Sherlock.Light.DarkActionBar"> <item name="vpiTabPageIndicatorStyle">@style/CustomTabPageIndicator</item> </style> <style name="CustomTabPageIndicator" parent="Widget.TabPageIndicator"> <item name="android:textColor">#FF000000</item> <item name="android:paddingTop">6dp</item> <item name="android:paddingBottom">6dp</item> <item name="android:paddingLeft">16dip</item> <item name="android:paddingRight">16dip</item> <item name="android:maxLines">2</item> </style>

  • How to perform a Depth First Search iteratively using async/parallel processing?

    - by Prabhu
    Here is a method that does a DFS search and returns a list of all items given a top level item id. How could I modify this to take advantage of parallel processing? Currently, the call to get the sub items is made one by one for each item in the stack. It would be nice if I could get the sub items for multiple items in the stack at the same time, and populate my return list faster. How could I do this (either using async/await or TPL, or anything else) in a thread safe manner? private async Task<IList<Item>> GetItemsAsync(string topItemId) { var items = new List<Item>(); var topItem = await GetItemAsync(topItemId); Stack<Item> stack = new Stack<Item>(); stack.Push(topItem); while (stack.Count > 0) { var item = stack.Pop(); items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } } return items; } EDIT: I was thinking of something along these lines, but it's not coming together: var tasks = stack.Select(async item => { items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } }).ToList(); if (tasks.Any()) await Task.WhenAll(tasks); UPDATE: If I wanted to chunk the tasks, would something like this work? foreach (var batch in items.BatchesOf(100)) { var tasks = batch.Select(async item => { await DoSomething(item); }).ToList(); if (tasks.Any()) { await Task.WhenAll(tasks); } } The language I'm using is C#.

  • 47 memory leaks. STL pointers.

Keep in mind i am cutting out alot of code to keep this post short. library.cpp #include "Library.h" #include "book.h" #include "cd.h" #include "dvd.h" #include <iostream> // general functions ItemSet allBooks; ItemSet allCDS; ItemSet allDVDs; ItemSetMap allBooksByAuthor; ItemSetMap allmoviesByDirector; ItemSetMap allmoviesByActor; ItemSetMap allMusicByBand; ItemSetMap allMusicByMusician; const ItemSet* Library::itemsForKeyword(const string& keyword) const { const StringSet* kw; ItemSet* obj = new ItemSet(); return obj; const Item* Library::addBook(const string& title, const string& author, const int nPages) { ItemSet* obj = new ItemSet(); Book* item = new Book(title,author,nPages); allBooks.insert(item); // add to set of all books obj->insert(item); return item; const Item* Library::addMusicCD(const string& title, const string& band, const int nSongs) { ItemSet* obj = new ItemSet(); CD* item = new CD(title,band,nSongs); return item; void Library::addBandMember(const Item* musicCD, const string& member) { ItemSet* obj = new ItemSet(); (((CD*) musicCD)->addBandMember(member)); obj->insert((CD*) musicCD); here is the library destructor..... Library::~Library() { Purge(allBooks); Purge(allCDS); Purge(allDVDs); Purge(allBooksByAuthor); Purge(allmoviesByDirector); Purge(allmoviesByActor); Purge(allMusicByBand); Purge(allMusicByMusician); } void Library::Purge(ItemSet &set) { for (ItemSet::iterator it = set.begin(); it != set.end(); ++it) delete *it; set.clear(); } void Library::Purge(ItemSetMap &map) { for (ItemSetMap::iterator it = map.begin(); it != map.end(); ++it) delete it->second; map.clear(); } so, basically item, cd, dvd class all have a set like this: typedef set<string> StringSet; class CD : public Item StringSet* music; and i am deleting it like: but those superclasses are not being called.. Item destructor is. CD::~CD() { delete music; } Do, i need a copy constructor? and how do i delete those objects i am creating in the library class? and how can i get the cd,dvd, destructor called? would the addbandmember function located in the library.cpp cause me to have a copy constructor? Any real help you can provide me to help me clean up this mess instead of telling me not to use pointers in my sets i would really appreciate. How can i delete the memory i am creating in those functions? I cannot delete them in the function!!

  • How to get a folder from CAML Query?

    - by Vijay
    I have a List which has a two level hierarchy of folders. Something like this: List Folder_1 SubFolder_1 Item 1_1_1 Item 1_1_2 SubFolder_2 Item 1_2_1 Item 1_2_2 Item 1_2_3 Folder_2 SubFolder_1 Item 2_1_1 Item 2_1_2 Item 2_1_3 SubFolder_2 Item 2_2_1 Item 2_2_2 I want to add a list item to a folder depending on some criteria. I don't want to loop through all folders as the number of folders is more. So, I thought of running a CAML query to get the folder. Below CAML Query gives me all folders in the list: <Where> <Eq> <FieldRef Name='FSObjType' /> <Value Type='int'>0</Value> </Eq> </Where> How can I add another condition to the above query so that I can get a specific folder when I know the exact folder name?

  • pbpaste/pbcopy for windows?

    - by ggrigery
    I'm looking for a quick and easy way to access clipboard contents from command line in Windows 7. I haven't been able to find anything searching the web so I was hoping someone in the community here might be able to help me. I found this article on a Google search. Apparently OSX has this functionality built in. This is exactly the functionality I'm looking for... Does anyone know of a Windows equivalent? Thanks in advance!

  • Extracting, then passing raw data into another class - How to avoid copying twice while maintaining

    - by Kache4
    Consider a class Book with a stl container of class Page. each Page holds a screenshot, like page10.jpg in raw vector<char> form. A Book is opened with a path to a zip, rar, or directory containing these screenshots, and uses respective methods of extracting the raw data, like ifstream inFile.read(buffer, size);, or unzReadCurrentFile(zipFile, buffer, size). It then calls the Page(const char* stream, int filesize) constructor. Right now, it's clear that the raw data is being copied twice. Once to extract to Book's local buffer and a second time in the Page ctor to the Page::vector<char>. Is there a way to maintain encapsulation while getting rid of the middleman buffer?

  • Coldfusion 8: Array of structs to struct of structs

    - by davidosomething
    I've got an array items[] Each item in items[] is a struct. item has keys id, date, value (i.e., item.id, item.date, item.value) I want to use StructSort to sort the item collection by a date Is this the best way to do it in ColdFusion 8: <cfset allStructs = StructNew()> <cfloop array = #items# index = "item"> <cfset allStructs[item.id] = item> <cfset unixtime = DateDiff("s", CreateDate(1970,1,1), item.date)> <cfset allStructs[item.id].unixtime = unixtime> </cfloop> <cfset allStructs = StructSort(allStructs, "numeric", "desc", "unixtime")> It's going to be dreadfully slow

  • Formatting an indented list in CSS

    - by Colen
    Hi, Let's say I have a list, with an arbitrary number of indentation levels, like so: Item Item Item Item Item Item Item Item Item Item Item If I'm displaying this list in an HTML document, how can I use CSS to handle the indentation? There might be an arbitrary number of indentation levels (although in practice there isn't going to be more than 5 or so). I don't want to create an "indent1" class that indents 10 pixels, an "indent2" class that indents 20 pixels, etc - that's clumsy. Is it possible to create a general rule that will indent by a certain distance based on an attribute value, or the position of an element in the hierarchy?
