• Who to contact regarding DBD::Advantage & bugs

  - by WarheadsSE

  I am in search of who specifically to contact at Sybase regarding Advantage Database Server's DBI driver, specifically DBD::Advantage. The only reference I can find is to one 'lancesc' in the README, but there are no references to a contact email, CPAN author etc. Inadvertantly I happened upon one StackOverflow user lancesc here. Would anyone happen to know who to contact regarding this? I do wish this was on CPAN. I've found a small bug regarding column quoting in the sql parser that they'd likely prefer to be made aware of. There are also several questions I have for them regarding failing functionality.

• Php efficiency question --> Database call vs. File Write vs. Calling C++ executable

  - by JP19

  Hi, What I wish to achieve is - log all information about each and every visit to every page ofmy website (like ip address, browser, referring page, etc). Now this is easy to do. What I am interested is doing this in a way so as to cause minimum overhead (runtime) in the php scripts. What is the best approach for this efficiency-wise: 1) Log all information to a database table 2) Write to a file (from php directly) 3) Call a C++ executable, that will write this info to a file in parallel [so the script can continue execution without waiting for the file write to occur ...... is this even possible] I may be trying to optimize unnecessarily/prematurely, but still - any thoughts / ideas on this would be appreciated. (I think efficiency of file write/logging can really be a concern if I have say 100 visits per minute...) Thanks & Regards, JP

• How to protect HtmlHelper code in MVC controls

  - by Oats

  I am writing a custom mvc control (commercial), and all of the control's code lives in the custom htmlhelper code that i will have to distribute to the user. I am ok with this for my commercial license sale, but for evaluating the controls, if i give out the htmlhelper code locally for my potential customers to evaluate, the user can simply "get" all the code and hence he may never buy it since he's got teh control code. How do i protect my htmlhelper code while somebody is evaluation my cusotm mvc controls? Is this a general problem or (I wish) i am missing something here? Thanks.

• How to keep the popup menu of a JComboBox open on populating it ?

  - by Stormshadow

  I have a JComboBox on my Panel. One of the popup menu items is 'More' and when I click that I fetch more menu items and add them to the existing list. After this, I wish to keep the popup menu open so that the user realizes that more items have been fetched however, the popup closes. The event handler code I am using is as follows public void actionPerformed(ActionEvent e) { if (e.getSource() == myCombo) { JComboBox selectedBox = (JComboBox) e.getSource(); String item = (String) selectedBox.getSelectedItem(); if (item.toLowerCase().equals("more")) { fetchItems(selectedBox); } selectedBox.showPopup(); selectedBox.setPopupVisible(true); } } private void fetchItems(JComboBox box) { box.removeAllItems(); /* code to fetch items and store them in the Set<String> items */ for (String s : items) { box.addItem(s); } } I do not understand why the showPopup() and setPopupVisible() methods are not functioning as expected.

• How can I stop a default event when using a named function in addEvent?

  - by Rupert

  Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

• Return specific HREF attribute using Xpath query

  - by Michael Pasqualone

  Having a major brain freeze, I have the following chunk of code: // Get web address $domQuery = query_HtmlDocument($html, '//a[@class="productLink"]'); foreach($domQuery as $rtn) { $web = $rtn->getAttribute('href'); } Which obviously gets the entire href attribute, however I only want 1 specific attribute within the href. I.e. If the href is: /website/product1234.do?code=1234&version=1.3&somethingelse=blaah I only want to return the variable for "version", so wish to only return "1.3" in my example. What's most efficient way to do this?

• handling activity destruction in multithreaded android app

  - by Jayesh

  Hi, I have a multithreded app where background threads are used to load data over network or from disk/db. Every once in a while user will perform some action e.g. fetch news over network, which will spawn a background AsyncTask, but for some reason user will quit the app (press back button so that activity gets destroyed). In most such scenarios, I make appropriate checks in the background thread after it returns from n/w i/o, so that it won't crash by accessing members of the activity that is destroyed by now. However some corner cases are left where crashes happen, because the background thread would access some member of activity that is now null. Do other Android developers have some generic/recommended framework to handle such scenarios? These are the times when I wish android would have guaranteed termination of all threads when activity destroys (in the same way that regular linux process cleans up when it's quit)... but I guess Android devs had good reasons for not exposing process lifetimes through the api.

• Python: Find X to Y in a list of strings.

  - by TheLizardKing

  I have a list of maybe a 100 or so elements that is actually an email with each line as an element. The list is slightly variable because lines that have a \n in them are put in a separate element so I can't simply slice using fixed values. I essentially need a variable start and stop phrase (needs to be a partial search as well because one of my start phrases might actually be Total Cost: $13.43 so I would just use Total Cost:.) Same thing with the end phrase. I also do not wish to include the start/stop phrases in the returned list. In summary: email = ['apples','bananas','cats','dogs','elephants','fish','gee'] start = 'ban' stop = 'ele' the magic here new_email = ['cats','dogs'] NOTES While not perfect formatting of the email, it is fairly consistent so there is a slim chance a start/stop phrase will occur more than once. There are also no blank elements.

• How do I implement a Google Latitude check-in feature on Windows Mobile?

  - by Carnotaurus

  I hope this is the correct forum. I wish to write a mobile application (MVC 4 mobile app) that extends Google Latitude for Windows Mobile 7 (or version 8 when launched in November). However, according to Google's own website (see http://www.google.com/mobile/latitude/), the check-in feature is not supported on Windows Mobile. So, how would I implement such a feature (not so interested in the UI here) using the technologies that I have mentioned? EDIT The implementation needs to store check-in data against a Google Latitude account.

• Extract part of HTML in C/Objective-C

  - by Dan

  Hi, I need to extract the detail content of a website while preserve all formatting of the division. The section I wish to extract is: ... <div class="detailContent"><p> <P dir=ltr><STRONG>Hinweis</strong>: Auf ... </p> </div> ... My current solution is to use HTMLParser from libxml2 and xpath to find the nodes and walk through all the nodes to reconstruct this piece of HTML. This is a long an complicated code. I' just wondering if there is an easier solution to extract part of HTML? Thanks.

• Servlets, long operations

  - by asrijaal

  Hi there, I'm refactoring a big piece of code atm where a long taking operation is executed in a servlet. Now sometimes I don't get a response after the operation has finished. (It has finished because it is printed into the logs) What I wish to achieve would some "fire and forget" behavior by the servlet. I would pass my params to the action and the servlet would immediately return a status (something like: the operation has started, check your logs for further info) Is this possible with servlet 2.5 spec? I think I could get such a behavior with JMS maybe any other solutions out there?

• Declaring a prototype of type "struct" - C

  - by Jamie Keeling

  I've been racking my brains on this for a while, I'm simply trying to create a method that returns a struct as I wish to return two int's. My prototype for the method is as follows: typedef struct RollDice(); Also the method itself: typedef struct RollDice() { diceData diceRoll; diceRoll.dice1 = 0; diceRoll.dice2 = 0; return diceRoll; } The compiler shows the error: "Syntax error: ')'" for both the prototype and actual method. The struct itself: typedef struct { int dice1; int dice2; }diceData; Is it obvious where I'm going wrong? I've tried everything I can think of. Thanks

• .net Attributes that handle exceptions - usage on a property accessor

  - by Mr AH

  Hi, well I know from my asp.net mvc experience that you can have attributes that handle exceptions (HandleErrorAttribute). As far as I can tell the Controller class has some OnException event which may be integral to this behaviour. However, I want to do something similar in my own code: dream example: public String MyProperty { [ExceptionBehaviour(typeof(FormatException), MyExEnum.ClearValue)] set { _thing.prop = Convert.ToThing(value); } } .... The code above obviously makes very little sense, but is close to the kind of thing I wish to do. I want the attribute on the property set accessor to catch some type of exception and then deal with this in some custom way (or even just swallow it). Any ideas guys?

• MATLAB: draw centroids

  - by Myx

  Hello - my main question is given a feature centroid, how can I draw it in MATLAB? In more detail, I have an NxNx3 image (an rgb image) of which I take 4x4 blocks and compute a 6-dimensional feature vector for each block. I store these feature vectors in an Mx6 matrix on which I run kmeans function and obtain the centroids in a kx6 matrix, where k is the number of clusters and 6 is the number of features for each block. How can I draw these center clusters in my image in order to visualize if the algorithm is performing the way I wish it to perform? Or if anyone has any other way/suggestions on how I can visualize the centroids on my image, I'd greatly appreciate it. Thank you.

• What's currently the best way to extend Excel using C#?

  - by user169867

  I have the professional versions of VS2008 & VS2010. I wish to add a couple buttons to a toolbar in Excel. When they are clicked I'd like to be able to open a form (either WinForms or WPF is fine) collect a few values from the user in the form and then take that data + read cell values from the current worksheet to perform some database operations. What's currently the best way to do this using C#? I'd greatly appreciate a pointer to any examples / tutorials. My understanding is that VS2010 has improved the process alot but I may have to deal w/ Excel 2003 which I don't think it supports. I get confused between Visual Studio 2008s Extensibility-Shared Addin template and other Office Addin templates I've seen. I'm not sure when which type of solution is appropriate. I'm new to Office development so I'd really appreciate any help to get me going on the right track. Thanks much.

• How can I maximally partition a set?

  - by Gregory Higley

  I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

• php search and replace

  - by Dave

  I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

• Android: chronometer widget and layout() method could not work well at the same time

  - by Lennard

  I write a test android app, in which there are only two views, a chronometer and a imageview. Using the layout() method of the imageview to dynamically change the position of it, I wish to implement drag-and-drop effect. It does work. However, each time the chronometer ticks, the imageview is always reverted to its original position, which seems that the whole screen is reloaded from the layout xml. So, does anybody know how to prevent the imageview from reverting to the original place, and let chronometer and drag-and-drop effect coexist? Thx

• How to find date ranges in records with consecutive dates and duplicate data

  - by alan s

  There's probably any easy solution for this, but I can't see it. I have a table with consecutive dates and often duplicate associated data for several of these consecutive dates: Date Col1 Col2 5/13/2010 1 A 5/14/2010 1 A 5/15/2010 2 B 5/16/2010 1 A 5/17/2010 1 A 5/18/2010 3 C 5/19/2010 3 C 5/20/2010 3 C Using MS T-SQL, I wish to find the start and end dates for each run of distinct Col1 and Col2 values: StartDate EndDate Col1 Col2 5/13/2010 5/14/2010 1 A 5/15/2010 5/15/2010 2 B 5/16/2010 5/17/2010 1 A 5/18/2010 5/20/2010 3 C Assumptions: There are never any missing dates. Col1 and Col2 are not null. Any ideas - preferably that don't use cursors? Many thanks, -alan

• Modifying a global variable from <a href>

  - by a_m0d

  I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?

• JQuery drag and Drop

  - by dremay

  I wish to create an Interface to choose Multiple answers using Drag & Drop rather than CheckBox near to the answers. User can choose two types of answers (Real Answer and a Fake Answer). The User has Two Images (for Real & Fake) on the answer page. User can drag an Image and drop near to the selected answer. It is possible to change the selection by moving the "image and drop over some other answer". I have used a "div formatted with an image" near to all answers, so user can drop the image (ie fake or real image) over this "div". I have used JQuery to move the "image" and drop over the "div". Now I need add the code to the "div" (ie container used to hold the image) to identify which "image is placed over it" ie either "fake or real".

• Alter Regular Expression to Return 2 Values Instead of 3 from userAgent String

  - by Jay

  I've taken a regular expression from jQuery to detect if a browser's engine is WebKit and gets it's version number, it returns 3 values extracted from the userAgent string: webkit/….…, webkit and ….… [“….…” being the version number]. I would like the regular expression to return just 2 values: webkit and ….…. I'm rubbish at regular expressions, so please can you give an explanation of the expression with your answer. The regular expression I'm currently working with and wish to improve is: /(webkit)[\/]([\w.]+)/. I appreciate all your help, thanks in advance!

• Disable page redirects using Greasemonkey

  - by Tomer Cohen

  A website I wish to tweak is using window.location in order to redirect specific users to a blocking page. That website is doing it in plain <script> tag, so it is impossible to bypass it by overriding the onload event using document.body.setAttribute('onload','');. Is there another way to inject my code to the page without using Firefox extensions such as NoScript? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript"> if (1) window.location="http://example.net" </script> </head> <body></body> </html>

• How to extract terms of specific data constructor from a list in Haskell

  - by finnsson

  A common problem I got in Haskell is to extract all terms in a list belonging to a specific data constructor and I'm wondering if there are any better ways than the way I'm doing it at the moment. Let's say you got data Foo = Bar | Goo , the list foos = [Bar, Goo, Bar, Bar, Goo] and wish to extract all Goos from foos. At the moment I usually do something like goos = [Goo | Goo <- foos] and all is well. The problem is when Goo got a bunch of fields and I'm forced to write something like goos = [Goo a b c d e f | Goo a b c d e f <- foos] which is far from ideal. How you do usually handle this problem?
