• How can I convince IE to simply display application/json rather than offer to download it?

  - by Cheeso

  While debugging jQuery apps that use AJAX, I often have the need to see the json that is being returned by the service to the browser. So I'll drop the URL for the JSON data into the address bar. This is nice with ASPNET because in the event of a coding error, I Can see the ASPNET diagostic in the browser: But when the server-side code works correctly and actually returns JSON, IE prompts me to download it, so I can't see the response. Can I get IE to NOT do that, in other words, to just display it as if it were plain text? I know I could do this if I set the Content-Type header to be text/plain. But this is specifically an the context of an ASPNET MVC app, which sets the response automagically when I use JsonResult on one of my action methods. Also I kinda want to keep the appropriate content-type, and not change it just to support debugging efforts.

• Getting information about where c++ exceptions are thrown inside of catch block?

  - by tfinniga

  I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.

• open window with dynamic content

  - by julio

  Is it possible to open a window from PHP that has predefined content? It's obvious how you can open a window from a javascript link that frames an existing page, or just do a target=_blank from a regular a tag that references an existing page. But I am generating a bit of content, and want that content to be opened in a new link (or streamed to the viewer)-- something like (clearly psuedo code!): $content = "Hello World. <br />Nice to meet you!"; <a href="#" target="_blank" content=$content>Open up!</a> Is this possible? Thanks!

• Can I get parameter names/values procedurally from the currently executing function?

  - by Pwninstein

  I would like to do something like this: public MyFunction(int integerParameter, string stringParameter){ //Do this: LogParameters(); //Instead of this: //Log.Debug("integerParameter: " + integerParameter + // ", stringParameter: " + stringParameter); } public LogParameters(){ //Look up 1 level in the call stack (if possible), //Programmatically loop through the function's parameters/values //and log them to a file (with the function name as well). //If I can pass a MethodInfo instead of analyzing the call stack, great. } I'm not even sure what I want to do is possible, but it would be very nice to be able to automatically output parameter names/values at runtime to a file without explicitly writing the code to log them. Thanks!

• 2 ajax forms on the same page posting same textbox

  - by rod

  Hi All, Is it possible to post, say like a value in a textbox, to 2 different ajax forms that are on the same page? It doesn't have to be at the same time? What I'm trying to do is this: I have a search page that searches for customers and displays them on a paged grid. Users can specify up to 5 parameters (5 textboxes) to narrow the search. On the same page I have an export option. Well since I want all the customers for the search and not just the paged data I need a way to post back to the server for this option passing the same parameters used in the grid. I'm using a ViewModel which would be nice if I can pass that back to the server rather than the individual search fields that are backed by the view model. Thanks, rodchar

• Problem when exiting search in iPhone

  - by camilo

  Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

• Seek a jQuery-based inplace HTML editor

  - by justSteve

  I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings. I'm hoping someone can help me narrow down the field according to these priorities... Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx

• How to switch data pins on/off on parallel port?

  - by Matt

  I want to simply switch certain data pins on and off, so that they can control a set of relays. I'm not asking about the hardware bit (should be easy), but I don't know where to begin writing the software. I don't want a high level library that can send bytes to a device - I literally want to switch on/off certain pins. I'm running Linux and I want to do this in Java, so would I just need a library? It would be nice if the library has good documentation and is easy to use, but if not then a short example code will help me get started.

• how to use constants in SQL CREATE TABLE?

  - by kchiu

  Hi, I have 3 SQL tables, defined as follows: CREATE TABLE organs( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE blocks( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE slides( title VARCHAR(16), -- ... other stuff ); The 3 fields above all use VARCHAR(16) because they're related and have the same length restriction. Is there a (preferably portable) way to put '16' into a constant / variable and reference that instead in CREATE TABLE? eg. something like this would be nice: CREATE TABLE slides( title VARCHAR(MAX_TITLE_LENGTH), -- ... other stuff ); I'm using PostgreSQL 8.4. thanks a lot, and Happy New Year! cheers.

• C# 3.5 Merge 2 lists of 2 different types

  - by Ehsan

  I have 2 generic Lists List<type1> L1 , List<type2> L2 in C# 3.5 Problem: type1 has an attribute called "key1" and type2 has an attribute called "key2" How to merge L1 and L2 on key1 = key2. Both lists are unsorted but I'm welcome to any ideas on how to sort the lists based on the attribute. I'd like to be able to merge the two lists on a key. I know it's not a dictionary and it would've been nice if it was but there is a very specific reason why they are lists which I will not get in to because that is irrelevant.

• Find an element in List of List, c#

  - by Sandy

  Hi, I have a list of lists as below: List<List <T> > userList Class T { string uniqueidentifier, string param2, int param2} I have a uniqueidentifier and i need to find the element T in the list that has the same 'uniqueidentifier' value. I can do it using two 'foreach' loops. This does not seem to be nice way doing things. I guess there should be some inbuilt method like 'Find' that does the same thing and is highly optimized.

• Any custom/third party Visual C# text box Controls with extra features?

  - by PlaZmaZ

  I'm writing a program that uses the textbox in visual C# to read a log file. When dealing with very large amounts of text, writing to the textbox is incredibly slow. The textbox also lacks many features. Are there any custom textbox controls that are faster, or even a sort of embedded editor (with ability to highlight certain words, indent, input bookmarks)? Many of the features I want are programmable, but it would be nice if there was a faster textbox or one that already had these features :) Thanks.

• Why do you sometimes need to write <typename T> instead of just <T> ?

  - by StackedCrooked

  I was reading the Wikipedia article on SFINAE and encountered following code sample: struct Test { typedef int Type; }; template < typename T > void f( typename T::Type ) {} // definition #1 template < typename T > void f( T ) {} // definition #2 void foo() { f< Test > ( 10 ); //call #1 f< int > ( 10 ); //call #2 without error thanks to SFINAE } Now I've actually written code like this before, and somehow intuitively I knew that I needed to type "typename T" instead of just "T". However, it would be nice to know the actual logic behind it. Anyone care to explain?

• How to controll (and emulate) monitor/projector on Linux?

  - by klew

  I would like to write some C/C++ program to controll monitor/projector attached to my computer. I've googled around, but I couldn't find almost anything that would lead me in some direction. Do you know where I can learn about it? What I would like to do is to write "Hello world" on an external monitor. It would be also nice to have some "monitor emulator" that will act as physicaly attached monitor (or to write program to emulate it). I'm not sure if it is possible. I couldn't find anything like this. I'm working on Ubuntu 9.10 with Gnome.

• Can a raw Lucene index be loaded by Solr?

  - by wynz

  Some colleagues of mine have a large Java web app that uses a search system built with Lucene Java. What I'd like to do is have a nice HTTP-based API to access those existing search indexes. I've used Nutch before and really liked how simple the OpenSearch implementation made it to grab results as RSS. I've tried setting Solr's dataDir in solrconfig.xml, hoping it would happily pick up the existing index files, but it seems to just ignore them. My main question is: Can Solr be used to access Lucene indexes created elsewhere? Or might there be a better solution?

• Does a native php (5+) function exist that does the following in 1 line?

  - by Vinh

  function array_value_from_key($array,$key) { return !empty($array[$key]) ? $array[$key] : null; } The reason I ask is because I have a class function that returns an array. Instead of having to do $myArray = myClass::giveMeArray(); $myValue = $myArray[$myKey]; I'd like to do something along the lines of $myValue = array_value_from_key(myClass::giveMeArray(),$myKey); When an object is returned, you can chain the object such as $myValue = myClass::giveMeObject()->aValue; Voila, nice and clean.. not being able to find what seems to be a simple and trivial function is driving me crazy... PS.. one more example of how I'd like to use such a function if(arrayKeyVal(aClass::giveMeArray(),$myKey)) { do_something(); }

• PHP Postgres constraint violation - can I get the constraint name somehow?

  - by RnR

  We have a web application talking to a Postgres SQL database at work - I've set up many constraints on the server to keep data consistent but we have problems with reporting nicely what it is that prevents the user from entering his (invalid) data at a given moment. The only thing we can get is "Constraint violation" but that isn't very descriptive, from perl or directly from PGAdmin we get nice info as to which constraint caused the failure (the constraint's name) - is there a way to do the same in PHP? We're able to upgrade PHP or use a different db access module if it would help so I'm interested in knowing if it's possible to do using any way that you could safely recommend.

• Difference between local and instance variables in ruby

  - by fflyer05

  I am working on a script that creates several fairly complex nested hash datastructures and then iterates through them conditionally creating database records. This is a standalone script using active record. After several minutes of running I noticed a significant lag in server responsiveness and discovered that the script, while being set to be nice +19, was enjoying a steady %85 - %90 total server memory. In this case I am using instance variables simply for readability. It helps knowing what is going to be re-used outside of the loop vs. what won't. Is there a reason to not use instance variables when they are not needed? Are there differences in memory allocation and management between local and instance variables? Would it help setting @variable = nil when its no longer needed?

• Matlab: plotting frequency distribution with a curve

  - by Kaly

  I have to plot 10 frequency distributions on one graph. In order to keep things tidy, I would like to avoid making a histogram with bins and would prefer having lines that follow the contour of each histogram plot. I tried the following [counts, bins] = hist(data); plot(bins, counts) But this gives me a very inexact and jagged line. I read about ksdensity, which gives me a nice curve, but it changes the scaling of my y-axis and I need to be able to read the frequencies from the y-axis. Can you recommend anything else?

• How to check an exectuable's path is correct in PHP?

  - by nickf

  I'm writing a setup/installer script for my application, basically just a nice front end to the configuration file. One of the configuration variables is the executable path for mysql. After the user has typed it in (for example: /path/to/mysql-5.0/bin/mysql or just mysql if it is in their system PATH), I want to verify that it is correct. My initial reaction would be to try running it with "--version" to see what comes back. However, I quickly realised this would lead to me writing this line of code: shell_exec($somethingAUserHasEntered . " --version"); ...which is obviously a Very Bad Thing. Now, this is a setup script which is designed for trusted users only, and ones which probably already have relatively high level access to the system, but still I don't think the above solution is something I want to write. Is there a better way to verify the executable path? Perhaps one which doesn't expose a massive security hole?

• Looking for a tutorial and/or example for the following: Annotation based Spring 3 with JPA and/or h

  - by Conor

  I want to learn Spring. I'd like to start with Spring 3. I want a simple tutorial and/or example. So no full blown web example please. Also - not a trivial example - so something incorporating persistence (e.g. JPA or hibernate) would be nice. Also - I don't want to get bogged down writing XML. So - Annotation based Spring 3 with JPA and/or hibernate. Yes - there is a good reference for Spring 3.0, but it's XML based. I can't find anything else useful. Thanks in advance.

• Android Google Directions

  - by Georg

  Some Questions about Android and Google Directions Service: Is there a native way on Android to use the Directions Service from Google or are there any nice Wrapper Frameworks? I would like to retrieve the time needed to get from A to B and maybe show the route in a table and/or map. As far as I know directions can only be retrieved for "walking" and "driving". Is there a way (maybe not from google) to get this Information also for public transports or "biking" ? Thx a lot for your help!

• parse unformatted string into dictionary with python

  - by user553131

  I have following string. DATE: 12242010Key Type: Nod32 Anti-Vir (30d trial) Key: a5B2s-sH12B-hgtY3-io87N-srg98-KLMNO I need to create dictionary so it would be like { "DATE": "12242010", "Key Type": "Nod32 Anti-Vir (30d trial)", "Key": "a5B2s-sH12B-hgtY3-io87N-srg98-KLMNO" } The problem is that string is unformatted DATE: 12242010Key Type: Nod32 Anti-Vir (30d trial) there is no space after Date before Key Type also it would be nice to have some validation for Key, eg if there are 5 chars in each box of key and number of boxes I am a beginner in python and moreover in regular expressions. Thanks a lot.

• Should I convert overly-long UTF-8 strings to their shortest normal form?

  - by Grant McLean

  I've just been reworking my Encoding::FixLatin Perl module to handle overly-long UTF-8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long UTF-8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?
