• "Send it to a friend" button on a webpage

  - by kender

  Hey, How often do we see stuff like "Send this page to a friend" on a webpages? Well, I see them quite often. My question is, how do you guys see it's effectiveness? If I hit a webpage that's interesting, and I think my friend would enjoy it, I can just copy the URL from my browser bar, paste it into the email and press "Send" button. In my opinion, it's usually faster and less mistake-aware then the button/link like this on the webpage. In addition, I'm not really sure what this website does with the emails I enter there - don't they store it and then sell for $1/100 addresses to spammers? My question is - when you design a website, do you put such links on the pages (it's often seen on sites with some news/articles)? Does it even make sense?

• HTML5 drag & drop: The dragged element content is missing in Webkit browsers.

  - by Cibernox

  I'm trying to implement something similar to a cart where you can drop items from a list. This items (<li> elements) has some elements inside (divs, span, and that stuff). The drag and drop itself works great. But the dragged element's image doesn't show its content in Webkit browsers. My list element has a border an a background color. In Firefox, the image is the whole item. In Webkit browsers, only the dragged element without content. I see the background and border, but without text inside. I tried to make a copy of the element and force it to be the image, but doesn't work. var dt = ev.originalEvent.dataTransfer; dt.setDragImage( $(ev.target).clone()[0], 0, 0); I have a simplified example that exhibit the same behavior: http://jsfiddle.net/ksnJf/1/

• Referenced assembly won't load in new thread on IIS 7

  - by DanielC

  I have a process in which a user uploads a file to a web site where the file is then processed and uploaded into the database. The process of validating the file could take several minutes so as soon as the file is uploaded I create a new thread and I do my processing on this second thread. This works great on my local machine but doesn't work at all on my IIS 7 test server. After some investigating I found the problem is that the process is trying to load a reference to Castle and it can't find the DLL. I have a copy of Castle DLLs in my bin and it works elsewhere in my app. I ran Fuslog and discovered that it is trying to load castle from the wrong location. It is trying to load from c:/windows/system32/inetsrv/. It appears that under IIS 7 the second thread is executing in a different context or something. So the question is what can I do to get it to find Castle in the application BIN folder?

• Class basic operators

  - by swan

  Hi, Is it necessary to have a copy constructor, destructor and operator= in a class that have only static data member, no pointer class myClass{ int dm; public: myClass(){ dm = 1; } ~myClass(){ } // Is this line usefull ? myClass(const myClass& myObj){ // and that operator? this->dm = myObj.dm; } myClass& operator=(const myClass& myObj){ // and that one? if(this != &myObj){ this->dm = myObj.dm; } return *this; } }; I read that the compiler build one for us, so it is better to not have one (when we add a data member we have to update the operators)

• How do I find the ruby interpreter?

  - by The Doctor What

  Inside a ruby script, how do I get the path to the ruby interpreter? Example script: #!/path/to/ruby puts `#{RUBY_INTERPRETER_PATH} -e "puts 'hi'"` #EOF Where RUBY_INTERPRETER_PATH is a mythical way of finding /path/to/ruby. This is just an example, though. I realize in this case that I could just copy /path/to/ruby into the script, but I don't want to do that. I want this to work "correctly" regardless of what the #! line says. Even if running under windows. Ciao!

• What's the current (as of April 2010) state of affairs regarding <object> vs <embed> in HTML?

  - by rvdm

  The age old question. <object> vs <embed>. From what I gather, <object> is the XHTML-compliant way of doing things, while <embed> is for legacy support. I'm currently building a Flash application that will contain a pre-made embedding code for users to copy and paste, and I'm wondering if it's feasible to simply dump the <embed> tag altogether. Which browsers would be unable to load my application if I gave my users an <object>-only embed code? Thanks :)

• Set argument pointer to point to new memory inside a function (without returning it) IN C

  - by user321605

  Hello, Hopefully my title was descriptive enough to attract the right help. I want to write a function that will return 1 thing, and modify a provided pointer in another. My current function declaration is . . . char * afterURL replaceURLS(char * body) What I want to do is copy all of body's data into a new string, and set body to point to this new data. I then want afterURL to point to a location within the new string. My issue is getting the actual pointer that is passed in to this function to point to the new data. Thanks in advance! Rob

• PHP editors for Ubuntu

  - by mepo

  What are the Light weight PHP editors available for ubuntu? And is there a ubuntu version of the Notepad++ editor. For those who haven't used Notepad++, do not confuse it with Notepad.exe. Notepad.exe is the lightweight Windows editor by Microsoft. Notepad++ is an Open Source programmer's text editor for Windows based on SciTE. It has syntax highlighting, code collapsing, language recognition, macro recording, regular expression search and replace across line breaks and in files on disk, copy filenames and paths to clipboard, and many other advance text editing tools. Only the more full-featured editors for Linux would be likely to be suitable replacements for Notepad++. Thanks

• MS Access Crashed an now all Form objects and code modules are missing

  - by owlie

  I was adding a form to our Access 07 db. I copied an existing form to use as a template, renamed it, and saved it. I opened a different form to check something and Access crashed. When I reopened the database it says: "Access has detected that this database is in an inconsistent state, and will attempt to recover the database." etc. When it reopened - all forms and reports were missing. Saved queries remain. The error message states that object recovery failures will be noted in a Recovery Errors table - but this table wasn't created. The links to the be database remained intact. The database is split - I was experimenting with a form on a front-end copy which might have something to do with it. Any ideas what would cause this (I can see loosing recent work - but nixing all form objects?!) And is there any chance of recovery?

• Why can't my c++ program find the necessary .dll file?

  - by RemiX

  I am trying to use OpenCV (a computer vision library), which appearently uses a few .dll files, located in C:\OpenCV\bin (which has been added to the system PATH variable). However, if I try to run a simple test program, it gives a system error: "The program can't start because highgui.dll is missing from your computer. Try reinstalling the program to fix this problem." If I copy the highgui.dll file into the system32 folder, it works, but I don't want to have to put all the necessary .dll files in the system32 folder. Does anyone know why the .dll file can't be found or what I should do to fix it? (I already checked all paths in the PATH variable for validity.)

• Databinding a list (in an object) to a combobox in VB.net

  - by Casey

  VB 2008 .NET 3.5 I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment. My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc. I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment." In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use. I have tried a few ideas, but none of them work properly. Any ideas on how to do this?

• Mercurial - How do you export your repo's source to a production site?

  - by orokusaki

  I've tried using archive in Tortoise HG by opening my repo change log. This doesn't seem to be anything like SVN's export command, where I can simply export a remote repository to the current directory. I use this to get a clean copy of my source for production (without notes and repository data). How can I do something like this in HG? Or, should I just use clone and deal with the repo related data manually? BTW, I need to do this all via command line since I'm not going to be using Tortoise HG on my Linux server. Any help is much appreciated.

• Adding my own items to Long Click on Text Box menu on android

  Hi all, I am currently developing an application for android. I'm not sure if this is possible but here it goes. When the user clicks and holds on a text box whether it is a website or a piece of software a menu is displayed which shows paste and input method. What I want to be able to do is add my own items to this menu and when the user clicks on my item it will load my app, they can select an item from a list view. It will then copy the contents and automatically paste it into the text field the user selected. Thanks for your help in this matter

• How to get the innerHTML of a XML document (AJAX)?

  - by JCOC611

  After an AJAX query, a XML file is returned. I'm able to "parse" that file, but when it comes to getting the "innerHTML" (or in this case "innerXML" lol) of an element, I fail. If the XML element, let's say "content", only contained text I could do: content.childNodes[0].nodeValue (assuming that content references the XML element "content"). But that element contains other elements: <stackoverflow reason="tribute to this page"> <content> <div><span><p>Some more HTML elements</p></span></div> </content> </stackoverflow> I need to copy the content of <content> to an existing <div> in the page, how could I do that? Ex. myDiv.innerHTML = content.innerHTML;

  - by lock

  im running on version 1.3.2.1 but on my client's server they had magento 1.3.0 so my previous code to display images for my local copy: echo $this->helper('catalog/image')->init($_product)->resize(163, 100); does not work on the client's installation looking at the results returned by their magento, ver 1.3.0 actually returns a url although it points to the skin's media folder is there a way to get the absolute image path for the image? or should i make changes somewhere else that would tell magento that the media directory should be on the root?

• populate a treeview with xml file using c#

  - by syedsaleemss

  Im using c#.net windows form application. I have an xml file that contains nodes. I need to populate a treeview with the nodes present in the xml file. Also avoid repeated node names. For this my idea is while populating the treeview, copy the node names into a list and there see if the node already exits. If it already exits, go to the next node else display it. List listOfNodes = new List(); listOfNodes.Add(xNode.Name.ToString()); //if (!(listOfNodes.Contains(xNode.Name.ToString()))) I was trying with this. but Im unable to do. Please suggest me with a proper code.

• SQL Server 2005: When clicking "Add" database I keep getting 'verify that the path or file exists'

  - by Code Sherpa

  When I right click on "databases" in Sql Server 2005 Management Studio and then Attach... Add I get the following error: C:\Documents and Settings\Administrator\My Documents\SQL Server Management Studio\ Projects\Path\To\MDF\And\LDF\Files\ cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. The answer is easy - the MDF and LDF files where removed when Nant (by way of my dev machine) issued a drop command. But, after replacing the MDF and LDF files, I want to reattach the database but the above error keeps coming up when I select "Add". Also, I have already "unattached" the database in question and it no longer appears on the left under "databases". I have tried to replace a copy of the MDF and LDF files in the folder being referenced and that didn't work. Any ideas as to how to gracefully get rid of this error?

• Duplicate array but maintain pointer links

  - by St. John Johnson

  Suppose I have an array of nodes (objects). I need to create a duplicate of this array that I can modify without affecting the source array. But changing the nodes will affect the source nodes. Basically maintaining pointers to the objects instead of duplicating their values. // node(x, y) $array[0] = new node(15, 10); $array[1] = new node(30, -10); $array[2] = new node(-2, 49); // Some sort of copy system $array2 = $array; // Just to show modification to the array doesn't affect the source array array_pop($array2); if (count($array) == count($array2)) echo "Fail"; // Changing the node value should affect the source array $array2[0]->x = 30; if ($array2[0]->x == $array[0]->x) echo "Goal"; What would be the best way to do this?

• Cannot find the certificate

  We get a T-SQL (SQL Server 2008 R2) error on BACKUP CERTIFICATE: ERROR_NUMBER 15151, SEVERITY 16, STATE 1, PROCEDURE -, LINE 8, MESSAGE: Cannot find the certificate 'certificate1', because it does not exist or you do not have permission.

• Performance: Subquery or Joining

  - by Auro

  Hello I got a little question about performance of a subquery / joining another table INSERT INTO Original.Person ( PID, Name, Surname, SID ) ( SELECT ma.PID_new , TBL.Name , ma.Surname, TBL.SID FROM Copy.Person TBL , original.MATabelle MA WHERE TBL.PID = p_PID_old AND TBL.PID = MA.PID_old ); This is my SQL, now this thing runs around 1 million times or more. Now my question is what would be faster? if I change TBL.SID to (Select new from helptable where old = tbl.sid) or if I add helptable to the from and do the joining in the where? greets Auro

• Accessing primitive properties from objects stored in a NSDictionary

  - by ChrisS

  Apologies if this is a basic question, I am just starting with Objective-C and trying to wrap things around in my head! I have a simple class of the form: @interface Whatever : NSObject { int somePrimitive; SomeObject* someObject; } @property (nonatomic) int somePrimitive; @property (nonatomic, retain) SomeObject* someObject; The class is more involved that this, but this illustrates the purpose. When I store instances of this class in a NSMutableDictionary: Whatever *whatever = [[Whatever alloc] init]; whatever.somePrimitive = 1; whatever.someObject = ...; [myDictionary setObject:whatever forKey:@"someKey"]; and then try to retrieve the object later: Whatever *result = [myDictionary valueForKey:@"someKey"]; then, result.someObject is ok to reference but, result.somePrimitive crashes. Does the NSDictionary not copy over the primitives of the object? Is the rule that the object stored in a dictionary should only contain objects?

• Comparing large strings in JavaScript with a hash

  - by user4815162342

  I have a form with a textarea that can contain large amounts of content (say, articles for a blog) edited using one of a number of third party rich text editors. I'm trying to implement something like an autosave feature, which should submit the content through ajax if it's changed. However, I have to work around the fact that some of the editors I have as options don't support an "isdirty" flag, or an "onchange" event which I can use to see if the content has changed since the last save. So, as a workaround, what I'd like to do is keep a copy of the content in a variable (let's call it lastSaveContent), as of the last save, and compare it with the current text when the "autosave" function fires (on a timer) to see if it's different. However, I'm worried about how much memory that could take up with very large documents. Would it be more efficient to store some sort of hash in the lastSaveContent variable, instead of the entire string, and then compare the hash values? If so, can you recommend a good javascript library/jquery plugin that implements an appropriate hash for this requirement?

• Prevent .htaccess syntax error

  - by seengee

  Hi, As part of one our system's we enable a user in the backoffice to add a block of 301 redirects should they need to. This is just a textarea which then populates a specific area of a .htaccess file. As much as this may seem insecure it has only previously used internally by people who know what they are doing but for various reasons they cannot access the specific file. We need now to allow more access to this function, not for the general public, but for people that probably have far less knowledge of regexp etc and syntax in htaccess files. Obviously the major concern here is the user enters some bad syntax and makes their entire site, including the backoffice where they could fix the issue, totally inaccessible without manual intervention. What approaches can i take to make sure that they do not break their site? A htaccess syntax check? copy the file elsewhere and check it doesnt generate a 500 error (with cURL or similar)?. Would welcome any ideas. Thanks.
