• Comparison of ASP.Net Reporting Solutions

  - by Brian MacKay

  This week my team spent way too much time trying to do simple things in reporting services, and I've decided to start evaluating other options. I know there are some good options out there now that aren't too expensive. I've heard that Telerik, ActiveReports, and a few others are widely used. I was hoping to get some first hand accounts regarding reporting tools that you've used. Specifically, I definitely want to hear your thoughts about: Pain points and gotchas you ran into. Ease of use for report design. It's a little bizarre to me that Access still seems to hold the throne in this area! What's your favorite tool? Anything I've missed that seems important to you. Thanks a lot!

• Windows Mobile Silverlight?

  - by eidylon

  Is it possible to develop Silverlight apps to run on WinMo devices? I see all around searching on the web - in articles from 2008 and 2009 - that they were adding Silverlight support in WinMo 6.1, for example: Internet Explorer Mobile The new version of Internet Explorer Mobile adds the ability to easily view full-screen Web pages and multimedia on the Web with a smartphone. Microsoft's press release states the new version takes advantage of "Internet Explorer 6 technologies" and supports industry standards such as H.264, Adobe Flash and Microsoft Silverlight. The update will be available to mobile phone partners in the third quarter of 2008, with the first Windows Mobile phones using the new version expected to be available by the end of 2008. But I have found an SL app supposedly geared for mobile devices (as much as I hate weatherbug), but when i try going there in PIE on my WinMo 6.1 device, it shows me the little "get silverlight" image button, but clicking it doesn't do anything. So, what is the story? Is SL/WinMo development possible, or ?

• C++ Winsock non-blocking/async UDP socket

  - by Ragnagard

  Hi all! I'm developping a little data processor in c++ over UDP sockets, and have a thread (just one, and apart the sockets) that process the info received from them. My problem happens when i need to receive info from multiple clients in the socket at the same time. How could i do something like: Socket foo; /* init socket vars and attribs */ while (serving){ thread_processing(foo_info); } for multiple clients (many concurrent access) in c++? I'm using winsocks atm on win32, but just get standard blocking udp sockets working. No gui, it's a console app. I'll appreciate so much an example or pointer to one ;). Thanks in advance.

• Wandering CGAffineTransformMakeRotation

  - by Joe

  Okay this is about to make me insane -- any help would be appreciated. I have two images which are part of a timer application. One is the needle/hand and the other is a little hub which is styled to look like the needle base. I'm using a CGAffineTransformMakeRotation to rotate the needle and the base stays stationary. The problem: there is like a 1-2px 'wander' to the needle's rotation which makes it look like it's moving off center in relation to the base. I have worked the base and needle image over in PS extensively, and both are dead center pixel wise -- seriously. My method to rotate the hand: -(IBAction) rotateSteamArrow{ CGAffineTransform rotate = CGAffineTransformMakeRotation( degreesSteam / 180.0 * 3.14159265); degreesSteam = degreesSteam + 1.5; if (degreesSteam <= 180) { [steamNeedle setTransform:rotate]; } else { [self handleSteamTimer]; [self toggleButton:(id)timerButton]; [self switchSound]; } }

• Recommended resources for learning MS Expression Blend

  - by fastmonkeywheels

  I've been designing applications using C# for some time now but I have the need to create a more custom application and Expression Blend was recommended to me. I've downloaded the free trial but it's a little fancier than I expected. I'm not a graphic designer and can't use photoshop to save my life, however I do have images provided by a graphic designer to use for this application. I'm looking for some good resources for learning Blend and using it as a front end to a C# application, much like I would a regular C# forum.

• Sql Server CE - Temporary disable auto increment on a specific collum

  - by Fábio Antunes

  Hi guys. I have this little question, thats been on my head for while now. Here it goes: Is it possible to temporary disable the Auto_Increment on the collum ID. So that i can add a new row to the table and being able specify the ID value when inserting the row. And then in the end enable the Auto_Increment again, and let do its work as usual? And if its possible how can i do it. The Table structure is very simple Collum Name (atributes) ID (Primary Key, Auto Increment, int, not null) Name (nvarchar(100), not null) Notice: The table name is: People. Lets also consider that the table already has data and cannot be changed. The database server is SQL Server CE. The SQL commands will be executed in a C# program, if its of any help. I really hope its possible, it would come very handy. Thanks

• Are the svn ruby bindings provided as a gem?

  - by user30997

  I see a couple dozen gems that relate to svn, but what little documentation I can find on any of them shows that they are command-line wrappers and misc helpers. (svn-command, svn-hooks, etc.) I've seen code in the wild that does things like: require 'svn/core' and SVN.Repos.add(...), but the author of that module pulled his svn ruby tools via apt-get. This would not be an option for me, as I'm developing a windows/osx tool. Which gem am I after? From there, I'm happy to dig through code in lieu of documents, but with a call to gem query --name-matches svn --remote returning about 30 hits, I need to narrow it down a bit first.

• using Spring JdbcTemplate for multiple database operations

  - by Joel Carranza

  I like the apparent simplicity of JdbcTemplate but am a little confused as to how it works. It appears that each operation (query() or update()) fetches a connection from a datasource and closes it. Beautiful, but how do you perform multiple SQL queries within the same connection? I might want to perform multiple operations in sequence (for example SELECT followed by an INSERT followed by a commit) or I might want to perform nested queries (SELECT and then perform a second SELECT based on result of each row). How do I do that with JdbcTemplate. Am I using the right class?

• Python 3.1.1 Class Question

  - by Protean

  I'm a new Python programmer who is having a little trouble using 'self' in classes. For example: class data: def __init__(self): self.table = [] def add(self, file): self.table.append(file) data.add('yes') In this function I want to have table be a variable stored in the class data and use add to modify it. However, when I run this script it gives me the error: Traceback (most recent call last): File "/Projects/Python/sfdfs.py", line 7, in <module> data.add('yes') TypeError: add() takes exactly 2 positional arguments (1 given) I assume that I am trying to call the function the wrong way in this instance, as this syntax is very similar to an example in the python documentation: http://docs.python.org/3.1/tutorial/classes.html

• Shopping Portal based on XML Data - XSLT or PHP?

  - by buggy1985

  For my bachelor thesis I want to implement a shopping (price comparison) portal prototype based on XML Data. The main requirement is to get a very clear and customizable HTML template, which should be hosted by the customer on his own webserver. I'm not very sure if XSLT meets this requirements, as it generates a lot of xsl-related code. It is not easy to understand for people with little HTML skills. I have some experience with the PHP templating engine Smarty. The syntax is much better, but I'm not sure if it's a good idea to parse the XML data with PHP, as it is very complex. Which language should I choose for a web application with high complexity? XSLT or PHP?

• How to track humans, but not spiders?

  - by johnnietheblack

  I am writing a nice little PHP/MySQL/JS ad system for my site - charging by impression. Therefore, my clients would like to be sure that they aren't paying for impressions caused by robots / spiders / etc. Is there a decently effective way to decipher between human and robot, without doing something obstructive like a captcha, or requesting "no index" or something? Basically, is there some sort of "name tag" that legit spiders have on so that my site knows their presence, therefore letting me react accordingly? And, if there isn't...how do ad companies like Google defend against this?

• CSS Position Absolute constant top margin

  - by Brian

  This question sounds simple but I'm an expert with CSS and I'm thinking it's impossible (a RARE thing). Is it possible to use CSS to give a a page a constant top margin if that div has no background (e.g. you can see through it)? Basically, I want the background image to be visible in the top 100px of a site, so that even when scrolling down, that top-margin remains in place. You can look at some live code here: http://cl.ly/40oY Here's a little infographic of what I'm attempting to do: http://cl.ly/40xt Thanks!

• Multithreading/Parallel Processing in PHP

  - by manyxcxi

  I have a PHP script that will generate a report using PHPExcel from data queried from a MySQL DB. Currently, it is linear in processing in that it gets the data back from MySQL, reads in the Excel template, writes the data to the template, then outputs it. I have optimized the code to the point that the data is only iterated over once, and there is very little processing done on the PHP side. The query returns hundreds of lines in less than .001 seconds, so it is running fast enough. After some timing I have found my bottlenecks to be (surprise, surprise) reading the template and writing the output. I would like to do this: Spawn a thread/process to read the template Spawn a thread/process to fetch the data Return back to parent thread - Parent thread will wait until both are complete Proceed on as normal My main questions are is this possible, is it worth it? If yes to both, how would you tackle it? Also, it is PHP 5 on CentOS

• Regex, encoding, and characters that look a like

  - by hack.augusto

  First, a brief example, let's say I have this "/[0-9]{2}°/" regex and this text "24º". The text won't match, obviusly ... (?) really, it depends on the character encoding. Here is my problem, I do not have control on which chars the user uses, so, I need to cover all possibilities in the regex /[0-9]{2}[°º]/, or even better, assure that the text has only the chars I'm expecting °. But I can't just remove the unknow chars otherwise the regex won't work, I need to change it to the chars that looks like it and I'm expecting. I have done this through a little function that maps the "look like" to "what I expect" and change it, the problem is, I have not covered all possibilities, for example, today I found a new "-", now we got three of them, just like latex =D - -- --- ,cool , but the regex didn't work. Does anyone knows how I might solve this?

• Embedded BI for ASP.NET

  - by Michael Shimmins

  Can anyone recommend a decent business intelligence & reporting application that can be integrated into an OEM application? Primary requirements are: Administrators can define cubes/dimensions etc (or we - the OEM - can predefine some) Report designers can easily inspect data by visually selecting dimensions, filters etc in an adhoc way that is quickly output with little upfront investment Report designers can design a report based on dimensions/filters and save their definition to be run as required Report viewers can view the reports defined by the report designers All of this plus in .NET that can be branded/integrated into our existing web application's look and feel. Permissions need to work off our user/groups system. I've found a few that look good, but they are all in Java and I don't want to ask our clients to install ASP.NET for the app, and then Java, tomcat etc just for reporting. Thanks

• Flex HDividedBox Divider backgroundColor

  - by Jeremy Mitchell

  Is there an easy way to set the backgroundColor of a HDividedBox's (or VDividedBox's) BoxDivider object(s)? A BoxDivider is the "divider" that has the drag handle on it. By default, the BoxDivider is transparent with the little handle image on it. There is a dividerSkin style that defaults to mx.skin.BoxDividerSkin which is a reference to a symbol in the Assets.swf file. Any ideas? Do I have to make an alternate skin? Is that my only option? Googling this led me to many solutions that were weird and hacky and frankly didn't seem to work. Thanks.

• Pros/Cons of document based database vs relational database

  - by damian

  I've been trying to see if I can accomplish some requirements with a document based database, in this case CouchDB. Two generic requirements: CRUD of entities with some fields which have unique index on it ecommerce web app like eBay (better description here). And I'm begining to think that a Document-based database isn't the best choice to address these requirements. Furthermore, I can´t imagine a use for a Document based database (maybe my imagination is too little). Can you explain me if I am asking pears to an elm when I try to use a Document based database for this requirements?

• Best tools to monitor Tomcat

  - by Pier Luigi

  Hi all, I'm searching free tools for monitor tomcat (traffic, memory usage, threads, requests, CPU, logs,...). I'm currently using lambdaprobe on Tomcat 5.5.x, but it seems that is no more developed (or not? the site lambdaprobe.org is always down for me...). Has someone good experiences to share? In lambdaprobe there are some info available only if tomcat is instrumented with JMX. Well, JMX is something of strange and mysterious for me. Is a good solution in a production server? It's worth to spend my (little) time to learn it?

• Namespace Orginization and Conventions

  - by Bob Dylan

  So I have a little bit of a problem. I working on a project in C# using The StackOveflow API. You can send it a request like so: http://stackoverflow.com/users/rep/126196/2010-01-01/2010-03-13 And get back something like this JSON response: [{"PostUrl":"1167342", "PostTitle":"Are ref and out in C# the same a pointers in C++?", "Rep":10}, {"PostUrl":"1290595", "PostTitle":"Where can I find a good tutorial on bubbling?", "Rep":10} ... So my problem is that I have some methods like GetJsonResponse() which return the above JSON and SaveTempFile() which saves that JSON response to a temporary file for later use. I not sure if I should create a class for them, or what namespace to put them under. Right now my current namespace hierarchy is like so: StackOverflow.Api.Json. So how should I organize these methods/classes/namespaces?

• Figuring if a link is clicked on a webView - iPhone

  - by Uygar

  Hi, I am using a custom webview to show a tabbar when user touches on the webview. But when I clicked on a link in a webview, tabbar is shown for a little time and then page loads. I am using this custom webview to detect touch: http://github.com/psychs/iphone-samples/blob/b772b963f2acf18d478b41b44555992fcd8d4f31/WebViewTappingHack/Classes/PSWebView.m Can I detect if a link clicked or not? Because a link stands on the webview, webview detects the touch and also it loads the page... I want to prevent it. Thanks in advance.

• XmlSerializer and Mark-up (Xml or Html)

  - by Kieron

  Hi, I've a requirement to serialize any class provided (decorated with the appropriate XmlElement/ XmlAttribute etc), but some of the properties may contain some sort of mark-up...usually HTML, but it could as easily be XML in the future. When trying to serialize the class the XmlSerializer crashes. I'd hope to be able to apply no more than an attribute to the property (currently set to XmlText) in the hope that it would wrap the content in CDATA[...], but that doesn't seem to work. I've seen several 'workarounds' like the one here, but I'd hoped for something a little less impactful for the developing consumer. Does anyone know of any 'nicer' less invasive solution...? Thanks, Kieron

• Managing data charts

  - by Tom Gullen

  My dbml file is just getting bigger and bigger and more unwieldy: I favoured an all-in-one approach as supposed to multiple data contexts because when I tried that it was near impossible to manage in code. I was advised it was better to have them all in one chart and the difficulty will be simply in managing this chart and not in code. The chart I've got is becoming a pain to manage, if I want to even remove a table and re-add it it sometimes takes a little while to manually find it! There isn't even a list I can find in VS2010 of the objects you have in that chart! Is there a better way of doing this?

• How can I customise Zend_Form regex error messages?

  - by Matt

  I have the following code: $postcode = $form-createElement('text', 'postcode'); $postcode-setLabel('Post code:'); $postcode-addValidator('regex', false, array('/^[a-z]{1,3}[0-9]{1,3} ?[0-9]{1,3}[a-z]{1,3}$/i')); $postcode-addFilters(array('StringToUpper')); $postcode-setRequired(true); It creates an input field in a form and sets a regex validation rule and works just fine. The problem is that the error message it displays when a user enters an invalid postcode is this: 'POSTCODE' does not match against pattern '/^[a-z]{1,3}[0-9]{1,3} ?[0-9]{1,3}[a-z]{1,3}$/i' (where input was POSTCODE) How can I change this message to be a little more friendly?

• When is a webapp called Beta, alpha, pre-alpha, or none

  - by dmontain

  I've come across many apps on the web that call themselves Beta. I've come across other apps that had an alpha designation. I've even come across some that called themselves pre-alpha, whatever that means (if you know please clarify). Then I've come across some really bad webapps that shouldn't have left the developer's computer and they didn't have any beta designations. I've also seen some well built apps that called themselves Beta, including Stack Exchange (the mother site of SO) which I believe is very full featured to be called a Beta. I'm a little confused. It seems people are doing it at their whims. Is there an established rule or a checklist that can help decide what stage an app is in (beta, alpha, pre-alpha, or none)? P.S. Please feel free to retag as appropriate.

• Some animation requests in a Silverlight application

  - by Mohit Deshpande

  I am making a flash card application. It shows the question and then a textbox for user input, all wrapped in a border or rectangle. So what I want is an animation that "flips" the rectangle or border upside-down and then their is text on the "back". Also, I want my application to APPEAR transition from one card to another by "flying off" the screen then "another" card comes in to replace the other one in the opposite direction. But actually I'm want just a little animation of the border or rectangle moving off the screen then coming back in, but in the opposite direction.
