  • Allow X Client Display through TCP on Lucid

    - by user42336
    On Karmic, to allow other PCs to open and X-Window on a station, one had to edit /etc/gdm.conf and change DisallowTCP to false. That file no longer exists on Lucid. I tried changing an entry in /etc/gdm/gdm.schemas (XML format) but that did not make a difference. Any ideas on where to go for this?

  • Speed Up the Help Dialog in Windows and Office

    - by Matthew Guay
    When you click help, you don’t want to wait for your computer to bring it to you.  Here’s how you can speed up the help dialog in Windows and Office. If you have a slow internet connection, chances are you’ve been frustrated by the Help dialog in Windows and Office trying to download fresh content every time you open them. This can be great if the updated help files contain better content, but sometimes you just want to find what you were looking for without waiting.  Here’s how you can turn off the automatic online help. Use Local Help in Windows Windows 7 and Vista’s help dialog usually tries to load the latest content from the net, but this can take a long time on slow connections. If you’re seeing the above screen a lot, you may want to switch to offline help.  Click the “Online Help” button at the bottom, and select “Get offline Help”. Now your computer will just load the pre-installed help files.  And don’t worry; if there’s a major update to your help files, Windows will download and install it through Windows Update.   Stupid Geek Tip: An easy way to open Windows Help is to click on your desktop or Start Menu and press F1 on your keyboard. Use Local Help in Office This same trick works in Office 2007 and 2010.  We’ve actually had more problems with Office’s help being tardy. Solve this the same way as with Windows help.  Click on the “Connected to Office.com” or “Connected to Office Online” button, depending on your version of Office, and select “Show content only from this computer”. This will automatically change the settings for Help in all of your Office applications. While this may not be a major trick, it can be helpful especially if you have a slow internet connection and want to get things done quickly.  Similar Articles Productive Geek Tips How to See the About Dialog and Version Information in Office 2007Speed Up SATA Hard Drives in Windows VistaMake Mouse Navigation Faster in WindowsSpeed up Your Windows Vista Computer with ReadyBoostSet the Speed Dial as the Opera Startup Page TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 FoxClocks adds World Times in your Statusbar (Firefox) Have Fun Editing Photo Editing with Citrify Outlook Connector Upgrade Error Gadfly is a cool Twitter/Silverlight app Enable DreamScene in Windows 7 Microsoft’s “How Do I ?” Videos

  • C# implicit conversions

    - by Chris Boden
    Hello, I'm currently working on an application where I need to load data from an SQL database and then assign the retrieved values into the properties of an object. I'm doing this by using reflection since the property names and column names are the same. However, many of the properties are using a custom struct type that is basically a currency wrapper for the decimal type. I have defined an implicit conversion in my struct: public static implicit operator Currency(decimal d) { return new Currency(d); } This works fine when I use it in code. However, when I have this: foreach (PropertyInfo p in props) { p.SetValue(this, table.Rows[0][p.Name], null); } It throws an ArgumentException stating that it cannot convert from System.Decimal to Currency. I'm confused since it works fine in any other circumstance.

  • How to use one script for diff and diff3 in Subversion?

    - by lamcro
    I have a perl script that determines what external diff to use depending on the file's content. I would like to use it determine external diff3 also. Which is the best method to know how my script is being called? I was planning to catch the last three parameters, and verify if they are all files, to use the diff3 options, but I'm hoping there is a cleaner method.

    - by user333771
    Hello to everybody..and greetings from Greece I have a C program for an exercise and it has a strange issue The program runs just fine on VS 2005 but it crashes on DEV-C++ and the problem that the problem is that the exercise is always evaluated against DEV-C++ The program is about inserting nodes to a BST and this is where the problem lies... Well i would really appreciate some help. enter code here #include <stdio.h> #include <stdlib.h> #include <malloc.h> typedef struct tree_node { int value; int weight; struct tree_node *left; struct tree_node *right; } TREE_NODE; /* The Following function creates a Binary Search Treed */ TREE_NODE *create_tree(int list[], int size); TREE_NODE *search_pos_to_insert(TREE_NODE *root, int value, int *left_or_right); /* this is the problematic function */ void inorder(TREE_NODE *root); /* Inorder Traversing */ TREE_NODE *temp; int main() { TREE_NODE *root; /* Pointer to the root of the BST */ int values[] = {10, 5, 3, 4, 1, 9, 6, 7, 8, 2}; /* Values for BST */ int size = 10, tree_weight; root = create_tree(values, 10); printf("\n"); inorder(root); /* Inorder BST*/ system("PAUSE"); } TREE_NODE *search_pos_to_insert(TREE_NODE *root, int value, int *left_or_right) { if(root !=NULL) { temp = root; if(value >root->value) { *left_or_right=1; *search_pos_to_insert(root->right, value, left_or_right); } else { *left_or_right=0; *search_pos_to_insert(root->left, value, left_or_right); } } else return temp;/* THIS IS THE PROBLEM (1) */ } TREE_NODE *create_tree(int list[], int size) { TREE_NODE *new_node_pntr, *insert_point, *root = NULL; int i, left_or_right; /* First Value of the Array is the root of the BST */ new_node_pntr = (TREE_NODE *) malloc(sizeof(TREE_NODE)); new_node_pntr->value = list[0]; /* ¸íèåóå ôçí ðñþôç ôéìÞ ôïõ ðßíáêá. */ new_node_pntr->weight = 0; new_node_pntr->left = NULL; new_node_pntr->right = NULL; root = new_node_pntr; /* Now the rest of the arrat. */ for (i = 1; i < size; i++) { insert_point = search_pos_to_insert(root, list[i], &left_or_right); /* THIS IS THE PROBLEM (2) */ /* insert_point just won't get the return from temp */ new_node_pntr = (TREE_NODE *) malloc(sizeof(TREE_NODE)); new_node_pntr->value = list[i]; new_node_pntr->weight = 0; new_node_pntr->left = NULL; new_node_pntr->right = NULL; if (left_or_right == 0) insert_point->left = new_node_pntr; else insert_point->right = new_node_pntr; } return(root); } void inorder(TREE_NODE *root) { if (root == NULL) return; inorder(root->left); printf("Value: %d, Weight: %d.\n", root->value, root->weight); inorder(root->right); }

  • FLEX: how to ignore MouseEvents from the container ?

    - by Patrick
    hi, I've some objects on the canvas, and I added eventListeners to these objects for MOUSE_UP event. I'm know checking if it works by tracing e.target.name, and I found out that the event is triggered twice, before on the element container (Canvas) and then the element itself. I read several times the documentation about Capture, Bubbling etc.. but I don't understand how to trigger the events only from the element itself... child.addEventListener(MouseEvent.MOUSE_UP, updateSelectedTags); private function updateSelectedTags(e:MouseEvent):void { Alert.show(e.currentTarget.name); //I have 2 alerts, one for canvas, the other one for the child } } thanks

  • jQuery autocomplete. Doesn't reveal existing matches.

    - by Alexander
    Hello fellow engineers. I have come across a problem I just can't solve. I am using autocomplete plugin for jQuery on an input. The HTML looks something like this: <tr id="row_house" class="no-display"> <td class="col_num">4</td> <td class="col_label">House Number</td> <td class="col_data"> <input type="text" title="House Number" name="house" id="house"/> <button class="pretty_button ui-state-default ui-corner-all button-finish">Get house info</button> </td> </tr> I am sure that this is the only id="house" field. Other fields that are before this one work fine with autocomplete, and it's basically the same algorithm (other variables, other data, other calls). So why doesn't it work like it should work with the following init. code: $("#house").autocomplete(["1/4","6","6/1","6/4","8","8/1","8/5","10","10/1","10/3","10/4","12","12/1","12/5","12/6","14","14/1","15","15/1","15/2","15/4","15/5","16","16/1","16/2","16/21","16/2B","16/3","16/4","17","17/1","17/2","17/4","17/5","17/6","17/7","17/8","18","18/1","18/2","18/3","18/5","18/95","19","19/1","19/2","19/3","19/4","19/5","19/6","19/7","19/8","20","20/1","20/2","20/3","20/4","21","21/1","21/2","21/3","21/4","22","22/9","23","23/2","23/4","24","24/1","24/2","24/3","24/A","25","25/1","25/10","25/2","25/4","25/5","25/6","25/7","25/8","25/9","26","26/1","26/6","27","27/2","28","28/1","29","29/2","29/3","29/4","30","30/1","30/2","30/3","31","31/1","31/3","32/A","33","34","34/1","34/11","34/2","34/3","35","35/1","35/2","35/4","36","36/1","36/A","37","37/1","37/2","38","38/1","38/2","39/1","39/2","39/3","39/4","40","40/1","41","41/2","42","43","44","45","45/1","45/10","45/11","45/12","45/13","45/14","45/15","45/16","45/17","45/2","45/3","45/6","45/7","45/8","45/9","46","47","47/2","49","49/1","50","51","51/1","51/2","52","53","54","55/7","66","109","122","190/8","412"], {minChars:1, mustMatch:true}).result(function(event, result, formatted) { var found=false; for(var index=0; index<HChouses.length; index++) //HChouses is the same array used for init, but each entry is paired with a database ID. if(HChouses[index][0]==result) { found=true; HChouseId=HChouses[index][1]; $("#row_house .button-finish").click(function() { QueryServer("HouseConnect","FillData",true,HChouseId); //this performs an AJAX request }); break; } if(!found) $("#row_house .button-finish").unbind("click"); }); Each time I start typing (say I press the "1" button), the text appears and gets deleted instantly. Rarely at all after repeated presses I get the list (although much shorter than it should be) But if after that I press the second digit, the whole thing disappears again. P.S. I use Firefox 3.6.3 for development.

  • Bring NSRunAlertPanel Dialogue to Front in Background Process

    - by mon4goos
    If you call NSRunAlertPanel() from a background process in Cocoa, the dialogue does not come to the front and instead stays behind other windows. This post shows that you can bring the dialogue to the front if you convert the process to a foreground process. If you keep the process a background process, however, is there any way to achieve this behavior?

  • Error accessing a Web Service with SSL

Any ideas, or suggestions?

  • Drupal print module: controlling layout in PDF files?

    - by WhyKiki
    So I'm trying to fix the layout of the PDF files for a specific content type. I'm messing around in the tpl.php file and can't find a way to modify individual fields. There's just the massive $print['content'] variable that contains all of the page content. So, is there a way to access each field?

  • Is there any "modern" text editor with command-line/minibuffer?

    - by Pedro Morte Rolo
    A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or Emacs/CUA are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. It would be nice if there was an editor that would cope with the modern de-facto standards out-off-the-box, but still provide a command-line/minibuffer to perform/explore the commands and learn its shortcuts. Is there such a thing? I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard-shortcut historical baggage. When I reffer to de-facto standards, I am not talking about Windows vs Whatever. Kate, gedit, Eclipse, Intelij or Textmate also follow the norm I am talking about and are not Windows editors. Please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives. Why don't I like emacs and vi: Emacs: Despite CUA mode, emacs has loads of modes that conflict with this (e.g. slime, ruby-mode, etc...) It would be nice to have something that would work out-off-the-box. VI: I do not like that it is Visual/Insert-based. I do not know how to browse the text-editor's commands. I do not like that it is so much tought for the terminal. I believe that it has the same problem that I mentioned for emacs. This question is starting to look like requirement analysis.. As de-facto standards I mean: Ctrol-XCV for cut-copy-paste Ctrol-A for select-all Contrl-Z for Undo Ctrol-Y for Redo Control-F for Searching Contrl-Space for auto-complete Shift-arrow for selection Control-arrow for word-navigation Alt-Arrow for moving

  • How can Java assignment be made to point to an object instead of making a copy?

    - by Matthew Piziak
    In a class, I have: private Foo bar; public Constructor(Foo bar) { this.bar = bar; } Instead of creating a copy of bar from the object provided in the parameter, is it possible to include a pointer to bar in the constructor such that changing the original bar changes the field in this object? Another way of putting it: int x = 7; int y = x; x = 9; System.out.print(y); //Prints 7. It is possible to set it up so that printing y prints 9 instead of 7?

  • Will the <b> and <i> tags ever become deprecated?

    - by CrazyJugglerDrummer
    (This is more of a curiousity question than any pending disaster :D ) So the <b> and <i> tags have been around since near the beginning of the web (I assume). But now we have CSS and many people apposing "stylistic html tags." They are stylistic tags, but they're really not so bad, as they save us from having to make a <span class="bold"> a whole bunch of times, reducing download times. Seeing as they don't take up much space, are easy to use, can possibly be useful to screen-readers, search engines, and other applications that don't care much about how a document looks, and removing them would break TONS of html code, I'm guessing probably not, but I still wanted to bring up the topic. :)

  • In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track

    - by Tony
    I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") }); FB.ensureInit(function () { FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback); }); However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error - FB.ApiClient is undefined I am also using the FBML fan tag to display the "become a fan" button: <fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan> And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan. The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

  • Can SPSiteDataQuery search both List and Libraries?

Is there a way to set the Lists property to search both at the same time?

  • Is AutoMapper able to auto resolve types base on existing maps

    - by Chi Chan
    I have the following code: [SetUp] public void SetMeUp() { Mapper.CreateMap<SourceObject, DestinationObject>(); } [Test] public void Testing() { var source = new SourceObject {Id = 123}; var destination1 = Mapper.Map<SourceObject, DestinationObject>(source); var destination2 = Mapper.Map<ObjectBase, ObjectBase>(source); //Works Assert.That(destination1.Id == source.Id); //Fails, gives the same object back Assert.That(destination2 is DestinationObject); } public class ObjectBase { public int Id { get; set; } } public class SourceObject : ObjectBase { } public class DestinationObject : ObjectBase { } So basically, I want AutoMapper to automatically resolve the destination type to "DestinationObject" based on the existing Maps set up in AutoMapper. Is there a way to achieve this?

  • Last Observation Carried Forward In a data frame?

    - by Tal Galili
    Hi all, I wish to implement a "Last Observation Carried Forward" for a data set I am working on which has missing values at the end of it. Here is a simple code to do it (question after it): LOCF <- function(x) { # Last Observation Carried Forward (for a left to right series) LOCF <- max(which(!is.na(x))) # the location of the Last Observation to Carry Forward x[LOCF:length(x)] <- x[LOCF] return(x) } # example: LOCF(c(1,2,3,4,NA,NA)) LOCF(c(1,NA,3,4,NA,NA)) Now this works great for simple vectors. But if I where to try and use it on a data frame: a <- data.frame(rep("a",4), 1:4,1:4, c(1,NA,NA,NA)) a t(apply(a, 1, LOCF)) # will make a mess It will turn my data frame into a character matrix. Can you think of a way to do LOCF on a data.frame, without turning it into a matrix? (I could use loops and such to correct the mess, but would love for a more elegant solution) Cheers, Tal
