• Asp.Net error reporting with stacktrace

  - by Helo

  I have an Asp.Net web site set up to log errors using Log4Net (in global.asax) and redirect users to a custom error page (set up in web.config with: ). On this error page the users have the opportunity to write about what they did when the error occurred and post the description back to us to help fix the problem. My question is this: How do i connect the error stacktrace to the users error report? It appears that .Net has handled the error when it was written to the log file and the custom error page has no information about the stacktrace. If only I could see the stacktrace from the custom error page code-behind my problem would be solved.

• POST data disapearing on large file upload

  - by DfKimera

  I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

• iOS get file size on disk

  - by F2_CMD

  I'm trying to get the size on disk of a file in iOS using Objective C. As of now I've been able to get the actual size of the file and other file information using NSFileManager and then getting the attributes attributesOfItemAtPath:error but not the size on disk. I also tried getting the file size from struct stat but again it doesn't give me size on disk.I tried using NSTask to make a call to du -h but iOS didn't allow me to fork other processes. Any ideas are welcome :) I know this questions is similar to many others but the difference is that I'm trying to do this in iOS and most of the methods used in other systems don't work here. Thanks

• Howto read system informations in C++ on windows and linux?

  - by f4

  I need to read system information like cpu/ram/disks usage in C++. Maybe swap, network and process too but that's less important. It has probably been done thousand of times before so I first tried to search for a library. Someone here suggested SIGAR, which seems to fit my needs but is GPL and it is for inclusion in a proprietary product. So it's not an option here. I feel like it's something not that easy to implement, as it'll need testing on several platforms. So a library would be welcome. If you don't know of any library, could you point me in the right direction for both platforms?

• Can i have a negative value as constant expression in Scala?

  - by Klinke

  I have an Java-Annotation that return a double value: @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface DoubleValue { double value(); } When i try to attach the annotation to a field in a scala class and the value is negativ like here: class Test { @DoubleValue(-0.05) var a = _ } i get an compiler error with the message: "annotation argument needs to be a constant; found: 0.05.unary_-". I understood that i need a numerical literal and i looked into the Scala Language Specification and it seems, that the - sign is only used for the exponent but not for the mantissa. Does someone has an idea how i can have a negative value as runtime information using annotations? Thanks, Klinke

• Console-App to get all open files for processes

  - by t.kehl

  Hi I am searching for a console-app (where I can pipe the output to a txt-file) which gives me a list of all current processes and the files which each process has open. The tool should also work when the user doesn't has administrativ-privilegues and it should also give file-path which are located on the network (UNC and absolute/mappings). Is there something like this which I can call from another tool and get the information? I am on a windows system. I have a open filename and need now to get the whole path for the file

• How do I construct a 3D model of a room from 2 stereo cameras? What is the determining factor to an

  - by yasumi

  Currently, I have extracted depth points to construct a 3D model from 2 stereo cameras. The methods I have used are openCV graphCut method and a software from http://sourceforge.net/projects/reconststereo/. However, the generated 3D models are not very accurate, which leads me to question: 1) What is the problem with pixel-based method? 2) Should I change my pixel-based method to feature-based or object-recognition-based method? Is there a best method? 3) Are there any other ways to do such reconstruction? Additionally, the depth extracted comes only from 2 images. What if I am turning the camera 360 degrees to obtain a video? Looking forward to suggestion on how to combine this depth information. Thank you very much :)

• Searching for the right pattern to handle login data

  - by stevebot

  Hi all, I'm working on a controller that handles logins for a Web app. These logins will come from multiple clients but will all contain the same data. However, depending on the client, this data will be interpreted into common entities for our webapp differently. For instance, we have a user code that gets sent in, and in one case we may use the first four digits of the code, and in another case 12 digits of the code to map to a field on a User entity. Instead of handling this all in the controller and having big nasty if blocks of logic, I would like to use a pattern to handle how this information gets ingested into our application. What are your opinions?

• Deciphering Encoding: Packet Analyzation Tools

  - by Zombies

  I am looking for better tools than wireshark for this. The problem with wireshark is that it does not format the data layer (which is the only part I am looking at) cleanly for me to compare the different packets and attempt to understand the third party encoding (which is closed source). Specifically, what are some good tools for viewing data, and not tcp/udp header information? Particularly, a tool that formats the data for comparison. To be very specific: I would like a program that compares multiple (not just 2) files in hex.

• performing a Http request on android

  - by rantravee

  Hi, Could someone provide the basic code to use if I want to perform a http request on android to the address "address" with the string "message" ? Also I'd like to check the server response and perform some actions if the right conditions meet , but I ' m unsure of how and when the server send back the response . My guess is that the response is gotten in a blocking function, or in an asynchronous function . Could you provide code or information on this as well ? Great thanks from a novice with too much on his head !

• Why is display:inline killing IE 8.0 performance?

  - by monstermensch

  I have an image gallery based on this jQuery plugin: http://jqueryfordesigners.com/demo/slider-gallery.html This works really well in Firefox, Chrome and even IE 7.0, but when I try it with more than 50 images in IE 8.0 the performance is incredible slow. Just hovering over the thumbnail brings the CPU load to 100%. At first I thought it's a Javascript problem, so I used the IE profiler, but the results were normal. Next I checked the CSS and finally found the cause: .sliderGallery UL LI { display: inline; } This gets the thumbnails to align horizontally. If I chance it to display:block, performance is fine and the scroller is still working but obviously it looks funny, because the thumbs are aligned vertically. My questions: Why does IE 8 have this problem with many display:inline elements What can I do to solve it I'll gladly provide more information if necessary.

• Is NoSQL ideal to store stats?

  - by Ivan

  I'm not terribly familiar with NoSQL systems, but I remember reading a while back that they are ideal to handle statistical data. Since I'm about to start writing code that will record data like "how many users were registered on each day", I was thinking I could use this as an opportunity to learn more about NoSQL if it fits the bill. If NoSQL is indeed ideal for this, could you provide me with some information as to why? And which specific systems are best suited for this particular need? Thanks!

• Can I add elements to a Java GUI?

  - by Asj

  I want to know how I can make a java program where an unknown amount of objects can be added to a GUI depending on user input. I can program in objects one at a time within the program, but I haven't seen a more dynamic program. Can I do that with Java? If not, what can I do it with? For more information, here's a picture. http://i6.photobucket.com/albums/y223/Asj127/CapProjIdea.jpg There can be more than one question per question block, and each question can have it's own question block.

• Moved X-cart site to Sub Directory - Need Help setting up Redirects

  - by Rich G

  I recently moved an x-cart site from a root directory to a sub directory, and also built a new Wordpress site under the root directory. The problem I am having is that I am trying to figure out a redorect combo that will show the search engines that the product pages are now under the sub directory (/store) but do not want the search engines to exclude the brand new site under the Root directory. I was thinking that if I could just have redirect any .html file (all of the product pages link to .html pages) that it would redirect to the same page just under the sub directory. The reason I cannot do everything one by one is because there are about 50k+ products that would need be changed. Any information and help would be greatly appreciated! Thank you in advanced!

• Get newly created window using Win32 API hooks

  - by Nathan W

  This may be a long short or not even possible but no harm in asking. What I am trying to do is monitor an application for any new windows it creates in its MDI control. I have implemented hooking in C# and can capture the MDICREATE window message but because I need to get information about the window after is has been created the MDICREATE message isn't much help because at that stage the window hasn't been created in the other application yet. Without going into to much detail I just need to be able to see when a new window has been created. Is this possible? Thanks

• php - track down premature headers leak

  - by user151841

  I'm using set_cookie() on a site. After adding some functionality, I'm getting Warning: Cannot modify header information - headers already sent by... error. The line number it references as to where the headers initiated from is the very line where set_cookie() is! And I checked, it's not being called twice. How can I track down these premature headers? I looked at the source code and didn't see any stray characters or anything before the error message starts ( I'm using xdebug, so the first thing is a , which I thought was me, but is actually the beginning of the xdebug message ). I've grepped my code for extra echo and so forth -- nothing. Can PHP tell me when and where the headers are starting? Or are they really starting on the set_cookie line, and if so, how have I gotten myself into this situation, and how do I get out?

• Do I need to include all fields in my entity framework model

  - by Jim B

  Quick question for everyone: Do I need to include all the database table fields on my EF model? For example; I've created a sub-model that only deals with tblPayment and associated tables. Now, I need to write a LINQ query to get some information about items. I would typically get this by joining tblPayment to tblInvoice to tblInvoiceItem to finally tblOrderItem. I'm wondering if when I add in those other tables, do I need to include all the fields for tblInvoice and tblInvoiceItem? Ideally; I'd just like to keep the fields I'd need to join on, as that would limit the possibility of my sub-model breaking if other fields on those tables are modified/deleted. Can I do this?

• iphone In app purchase

  - by edie

  Hi... I'm adding in-app purchase on my application. I have a view that displays information about the product and one button for purchasing the product. My question was how can I stop the user to tap again the buy button so that the StoreManager will only call my Buy method once? Because sometimes I had tapped it twice that's why two alertView shows up asking about the purchase. Should I set the button "enabled property" to no after I tap. Any suggestions that would be good about this... thanks in advance.

• Aligning Android Button To Bottom in RelativeLayout??

  - by MobiKnow

  I'm trying to align a button to the bottom right and bottom left of my screen, using a RelativeLayout. I want to do this to keep the same relative layout across different screen sizes. Currently the buttons on my screen move up/down depending on the resolution of the screen. 320x480 puts the buttons higher on the screen versus 480x800. I'm trying to get my screens to look the same between the two sizes. Any information you can provide is greatly appreciated. Thanks, MobiKnow.

• Java Web App: Passing form parameters across multiple pages

  - by digiarnie

  Hi, what is the best practice or best way of passing form parameters from page to page in a flow? If I have a flow where a user enters data in a form and hits next and repeats this process until they get to an approval page, what ways could I approach this problem to make the retention of data as simple as possible over the flow? I guess you could put all the information as you go in the session but could you get into memory issues if a lot of people are using your app and going through the flow at the same time?

• Location accuracy of Google Analytics for Android

  - by BadCash

  When testing Google Analytics (version 2) for an Android project, I noticed that the Real Time map shows my location to be about 200 miles from my actual location. I'm running my project on a physical device, which leads me to believe that Google Analytics doesn't actually send any location information, but rather gets it from the phones IP address when the data is sent to Googles server. Is there any way to alter this behavior and provide my own location data using getLastKnownLocation() for example? Sending it as an actual Label/Action string would of course work, but that means I can't use Google Analytics fancy map feature to view where my users are coming from.
