  • What encoding does Flash Builder use to send non-English data to servers?

    - by Ole Jak
    In my site I use Unicode... I hoped when I'll connect Flash Builder to my server (using Data - connect to HTTP ) It will work with my API sending Russian text as UTF-8 but instead it sends Þûõó ïúушúøý to my API and so to DB and so on instead of my favourite UTF-8 &#1056;&#1091;&#1089;&#1089;&#1082;&#1086;&#1077; &#1048;&#1084;&#1103; 2... So what encoding uses flash builder and How to make Flash Application send UTF-8 data to my server or some other readable format?

  • DataGridView: can you add an unbound column to a Data Bound grid?

    - by Jack Johnstone
    I´m using Visual Studio 2008, C# DataGridView: can you add an unbound column to a Data Bound grid? It seems pretty simple, just select the properties ("DataGridView Tasks box") for the data bound DataGridView, and select Add unbound column. However, when in runtime there will be a System.FormatException - which I can understand, as I don´t know how to "initialize" the cells in the new unbound columns. I was planning initializing it programmatically via CellFormatting event - but so far I´m failing. Any tips? Just want to get it up and running in SOME way...

  • Is there a library / tool to query MySQL data files (MyISAM / InnoDB) without the server? (the SQLit

    - by MGW
    Oftentimes I want to query my MySQL data directly without a server running or without having access to the server (but having read / write rights to the files). Is there a tool or maybe even a library around to query MySQL data files like it is possible with SQLite? I'm specifically looking for InnoDB and MyISAM support. Performance is not a factor. I don't have any knowledge about MySQL internals, but I presume it should be possible to do and not too hard to get the specific code out? Thank you for any suggestions!

  • why arrayfun does NOT improve my struct array operation performance

    - by HaveF
    here is the input data: % @param Landmarks: % Landmarks should be 1*m struct. % m is the number of training set. % Landmark(i).data is a n*2 matrix old function: function Landmarks=CenterOfGravity(Landmarks) % align center of gravity for i=1 : length(Landmarks) Landmarks(i).data=Landmarks(i).data - ones(size(Landmarks(i).data,1),1)... *mean(Landmarks(i).data); end end new function which use arrayfun: function [Landmarks] = center_to_gravity(Landmarks) Landmarks = arrayfun(@(struct_data)... struct('data', struct_data.data - repmat(mean(struct_data.data), [size(struct_data.data, 1), 1]))... ,Landmarks); end %function center_to_gravity when using profiler, I find the usage of time is NOT what I expected: Function Total Time Self Time* CenterOfGravity 0.011s 0.004 s center_to_gravity 0.029s 0.001 s Can someone tell me why? BTW...I can't add "arrayfun" as a new tag for my reputation.

  • WindowsPhone App data connection FAILS in MarketPlace published App but WORKS in Visual Studio development (same XAP)

    - by Tom
    Tearing my hair out(!) My last App update has been accepted and released by MarketPlace but the remote server data connection does NOT work/connect from the downloaded App (from MarketPlace). However, the same App (the accepted XAP) when I'm running it from Visual Studio, using the same remote server address works just fine. WHY!... Has anyone else ever run into anything like this? Here's the remote path: http://www.streamcommunication.com/ZenAwaken/DownloadableCollections.xml I can load that to a browser and retrieve the XML When I'm in Visual Studio I can connect via that path and retrieve the file and consume the data BUT!! The exact same XAP which has been accepted and distributed by Windows Phone marketplace FAILS. Is it possible that MarketPlace does something (encryption?) to the XAP that would corrupt the path string? Any thoughts or experiences would be very helpful! Tom

  • In R, how do you get the best fitting equation to a set of data?

    - by Matherion
    I'm not sure wether R can do this (I assume it can, but maybe that's just because I tend to assume that R can do anything :-)). What I need is to find the best fitting equation to describe a dataset. For example, if you have these points: df = data.frame(x = c(1, 5, 10, 25, 50, 100), y = c(100, 75, 50, 40, 30, 25)) How do you get the best fitting equation? I know that you can get the best fitting curve with: plot(loess(df$y ~ df$x)) But as I understood you can't extract the equation, see Loess Fit and Resulting Equation. When I try to build it myself (note, I'm not a mathematician, so this is probably not the ideal approach :-)), I end up with smth like: y.predicted = 12.71 + ( 95 / (( (1 + df$x) ^ .5 ) / 1.3)) Which kind of seems to approximate it - but I can't help to think that smth more elegant probably exists :-) I have the feeling that fitting a linear or polynomial model also wouldn't work, because the formula seems different from what those models generally use (i.e. this one seems to need divisions, powers, etc). For example, the approach in Fitting polynomial model to data in R gives pretty bad approximations. I remember from a long time ago that there exist languages (Matlab may be one of them?) that do this kind of stuff. Can R do this as well, or am I just at the wrong place? (Background info: basically, what we need to do is find an equation for determining numbers in the second column based on the numbers in the first column; but we decide the numbers ourselves. We have an idea of how we want the curve to look like, but we can adjust these numbers to an equation if we get a better fit. It's about the pricing for a product (a cheaper alternative to current expensive software for qualitative data analysis); the more 'project credits' you buy, the cheaper it should become. Rather than forcing people to buy a given number (i.e. 5 or 10 or 25), it would be nicer to have a formula so people can buy exactly what they need - but of course this requires a formula. We have an idea for some prices we think are ok, but now we need to translate this into an equation.

  • How do I submit really big amounts of data to a form?

    - by William Calleja
    I have an HTML from that's posting a really big amount of data which is eventually being saved into an SQL Server 2005, the form is as follows: <form name="frmForm" method="post" action="saveData.aspx"> the target page takes the content of a control within the form and saves it to the database through a normal SQL insert statement. However only a portion of the data is being saved. The field in the database is an ntext. Should I use a different field? Or is something happening while I'm transferring from one page to another? Or even still there's something happening when I'm sending the really big SQL statement through c# in saveData.aspx?

  • How to query range of data in DB2 with highest performance?

    - by Fuangwith S.
    Usually, I need to retrieve data from a table in some range; for example, a separate page for each search result. In MySQL I use LIMIT keyword but in DB2 I don't know. Now I use this query for retrieve range of data. SELECT * FROM( SELECT SMALLINT(RANK() OVER(ORDER BY NAME DESC)) AS RUNNING_NO , DATA_KEY_VALUE , SHOW_PRIORITY FROM EMPLOYEE WHERE NAME LIKE 'DEL%' ORDER BY NAME DESC FETCH FIRST 20 ROWS ONLY ) AS TMP ORDER BY TMP.RUNNING_NO ASC FETCH FIRST 10 ROWS ONLY but I know it's bad style. So, how to query for highest performance?

  • How to enable indexing of pages with dynamic data?

    - by mithunb
    I have a site that has certain urls that point to pages with permanent data and others that point to dynamic web pages. Google indexes both these regularly. By the time a user finds one of the dynamic content urls, the data on the page has already changed and the user does not find what he was looking for. Further, the dynamic url pages contains links to the permanent urls (which I want Google or any crawler to index). Google crawler controls (webmaster tools) cannot be made to read urls from a page but not index them. Solutions? crawling strategies *system architecture*.

  • Best way to Store Passwords, User information/Profile data and Photo/Video albums for a social websi

    - by Nick
    Need some help figuring out how to best Store Passwords, User information/Profile data and Photo/Video albums for a social website? For photos/videos the actual photo/video + even encrypting the URL with the IDs to the photo/videos so other users cannot figure it out. Creating a site like myspace and designing retirement documents but i am unsure how to specify the security requirements for the database. Two things: 1) Protect from outside users 2) Protect all these from employees being able to access this info For #2, the additional question is: If we encrypt the user info and password so even the system admins cannot get in, how can we retrieve the user data tomorrow if someone flags the user's account as spam and admin needs to check it out or if law enforcement wants info on a user? Thanks.

  • Push, parse & import "selected" data, text, info blobs from Webpages/ Emails as Event/ Appointment to standard Calendar directly or as .ics file?

    - by Alex S
    Any tool, plugin, extension, script/ code to push "selected" data, text, information blobs from Web pages, Emails etc, then parsed and imported to structured Event, Appointment (e.g. .ics) on a standard Calendar like Outlook, Google, iCal? If not, what and how could I use some scripting, coding or existing tools, extensions to add on top and do this. I come across a lot of unstructured information on Webpages, Emails, FB events etc. where I just want to add that information to my Calendar. Instead of entering all the information by hand all the time, there should be an easy enough way to have the information get parsed, organized and imported to a Calendar... Either directly to a calendar from source or Translated to a standard format such as .ICS that can be imported & saved easily. Would love to see some suggestions for this incorporating one or more of the following: on Windows with Chrome & Outlook on iPhone/ iPad to its Calendar PS: I'll come back and see if I can add more information to this question and to answer it as well. I have not found a solution yet.

  • How to Return A File and a strongly Typed data at the same time?

    - by chobo2
    Hi I am using asp.net mvc 1.0 and I want to return a XML file but I also want to return a strongly typed data back so I can update some fields. Like the XML file will contain users who failed to be inserted into the database. So I want that to appear as a dialog save box what asp.net mvc return file() would do. However I also want to return on the page like values like how many users failed to be added, how many users where added, etc. So I want to use scafolding with the class file I want to pass it along. If this was a view I could pass it along as an object model but I don't see a parameter for that in File(). I also don't want to save the xml file onto the harddrive I want to do it through memory. So have a link that would display on the page to download the file and show the the data I want would not be desired.

  • Working with three dimensional data in an HTML (ASP.NET) table.

    - by ProfK
    I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

  • All things equal what is the fastest way to output data to disk in C++?

    - by user260197
    I am running simulation code that is largely bound by CPU speed. I am not interested in pushing data in/out to a user interface, simply saving it to disk as it is computed. What would be the fastest solution that would reduce overhead? iostreams? printf? I have previously read that printf is faster. Will this depend on my code and is it impossible to get an answer without profiling? Edit: Output data needs to be in text format, whether tab or comma separated. This will require formatting, precision, etc. Running in Windows.

  • SQL: Is it quicker to insert sorted data into a table?

    - by AngryWhenHungry
    A table in Sybase has a unique varchar(32) column, and a few other columns. It is indexed on this column too. At regular intervals, I need to truncate it, and repopulate it with fresh data from other tables. insert into MyTable select list_of_columns from OtherTable where some_simple_conditions order by MyUniqueId If we are dealing with a few thousand rows, would it help speed up the insert if we have the order by clause for the select? If so, would this gain in time compensate for the extra time needed to order the select query? I could try this out, but currently my data set is small and the results don't say much.

  • What is the correct approach i should use for an application that requires amazon S3 uploads and SimpleDB data management?

    - by Luis Oscar
    I am developing an application for iOS and that is going smoothly, the problem is that I am very new at server sided things. I am totally confused about how to correctly use Amazon Web Services for this purpose. What I want to do is very simple. I want my application to be able to query a servlet hosted in EC2 to be able to retrieve pictures and data based on some criteria from S3 and SImpleDB respectively. Also the application should be able to upload pictures into a S3 bucket and register the information in the SImpleDB. My main concerns are security and costs, So far i was using Amazon Token Vending Machine but I haven't been successful when trying to customize it, and while researching I discovered that on the long run it is very expensive. The ultimate goal is to handle a "social" picture service for my iOS application. Being able to register new users, authenticate these users. See what permissions they have to which pictures from the bucked. And all this without having to worry about Third party people from accessing the private pictures of my users. Sorry for this question but I am really clueless about how to handle this... I have tried reading many articles but all these server stuff looks very scary.

  • Are there SqlExceptions which throw but commit their data anyway?

    - by Jonn
    I've recently encountered the error: System.Data.SqlClient.SqlException: The transaction log for database 'mydatabase' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases on one of my windows services. It's supposed to retry after catching an Sql Exception, what I didn't expect was that it seemed like the data was still going through (I'm using an SqlBulkCopy btw) regardless of it throwing an exception. I've never encountered this scenario before. I'd like to know if there are other scenarios where such a thing like this might happen, and if this thing is entirely possible at all in the first place? PS. If anyone knows the error code to the above exception, that would help a great deal as well.

  • How do I pass custom action data from a Visual Studio Setup MSI to an output project via a Merge mod

    - by Lex
    I have a fully working Setup project within Visual Studio 2008 that takes inputs from a UI and passes them via a Custom Action to the output - this works perfectly. Now I have to change this so that the UI is still in a setup project but that the output is within a merge module. The current Custom Action Data looks much like the following with EditHostUrl coming from a UI dialog editbox. /HostUrl="[EditHostUrl]" I now need to pass this value to the merge module and then from there use it as an input for the custom action data to the project output but there does not seem to be any documentation on how to achieve this. To be clear Wix/InstallShield etc... are not currently options. I would also rather not embed the UI within the merge module (for reasons of separation and also it's not supported out of the box with visual studio).

  • Where does the data model go in a Prism app?

    - by HawkeyeJoeS
    I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

  • how to send database data to a MySQL server to update the server database.

    - by haisergeant
    Hi everyone, I am developing Smoking counter and I need to send all the smoking record (about the time user smoking) to database on the server. The server database is MySQL database. I knew that I must have send data to PHP page/script, and this page/script will run on the data to insert record to database. I would like to know: is there another way to update database, because I don't have knowledge about PHP. I used to work on java and c/c++/objective-c. If you know another way to do this task, please let me know. Any help would be appreciated.

  • Which MS technologies would be suited for a data intensive application?

    - by steve.tse
    I'm a junior VB.net developer with little application design knowledge. I've been reading a lot of material online regarding different design patterns, frameworks, and methodologies. It's become a bit confusing for me. Right now I'm trying to decide on what language would be best suited to convert an existing VB6 application (with SQL server backend.) I need to update the UI and add more user functionality and reporting capabilities. Initially I was thinking of using WPF and attempting the MVVM model for this big project. Reports would be generated from SSRS. A peer suggested using ASP.net and I don't have enough experience to determine what would be better. The senior programmers here are stuck on using VB6 and don't have any input on what to use. They are encouraging me to use the latest technologies. This application would be for ~20 users in a central location. Ideally I would stick to a Microsoft .net language. Current interface is similar to a datagrid table where the user would click in to see the detail of each record. They would need to have multiple records open at any given time. I look forward to all the advice I can get. EDIT 2010/04/22 2:47 PM EST What is your audience? Internal clients within an intranet How complex are the interactions you expect to implement? not very... displaying data from SQL server to UI. Allow user updates to said data. Typically just one user modifying a record. Do you require near real-time data updates? no How often do you expect to update the application after the first release? twice/year Do you expect a well-defined set of client platforms? Yes, windows xp environment, potentially upgrading to Win7. Currently in IE.6 moving to IE7 or 8 within a couple of months. Do users need access from anywhere? No, just from their PC.
