• Workaround for Outlook 2007 for wrapping text around image with margin?

  - by DavidW

  As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

• Multiple Servers with identical services

  - by Jerry Bailey

  I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

• Attributed strings in UITableViewCells without WebView?

  - by arnekolja

  Hello, does anyone know if there's a way in with 3.0+ to display attributed strings within a UITableViewCell without using a UIWebView for that? I need to display a string with linked, tappable substrings as the typical detailTextLabel. I wouldn't mind exchanging this UILabel against another type of view, but I think a UIWebView could be just too slow when rendering a table with hundrets of cells. Or does someone have opposite experiences here? So my question is: what's the best way to achieve mixed strings in a very large table without a great performance hit? I searched for this almost a whole day now, but I can only find old posts mentioning that there's no attributed string on the iPhone (outdated, as this was pre-3.0) and/or saying that they use a UIWebView for that. But really, I don't think this would perform very well on large tables, would it? Many, many thanks in advance Arne

• JQuery/JavaScript div tag "containment" approach/algorithm?

  - by Pete Alvin

  Background: I've created an online circuit design application where div tags are containers that contain smaller div containers and so forth. Question: For any particular div tag I need to quickly identify if it contains other div tags (that may in turn contain other div tags). I've searched JQuery and I don't see any built-in routine for this. Does anyone know of an algorithm that's quicker than O(n^2)? Seems like I have to walk the list of div tags in an outer loop (n) and have an inner loop (another n) to compare against all other div tags and do a "containment test" (position, width, height), building a list of contained div tags. That's n-squared. Then I have to build a list of all nested div tags by concatenating contained lists. So the total would be O(n^2)+n. There must be a better way?

• Win32 Window Menu is appearing along left side instead of across top of window

  - by Khat

  I think I may be using a wrong window style or something or maybe just adding the menu to the window incorrectly. I'll post a link to an image here so you can see what I mean about the menu not diplaying correctly: http://img707.imageshack.us/img707/4828/wtfmenu.jpg And here's a link to the code that creates the menu and the window: http://pastebin.com/CBrSVXUD I'm sure I'm missing something simple and dumb in the labyrinth of styles, settings and etc that are part and parcel for the Win32 API. Has anyone seen this before and know what I'm doing wrong? I just want a 'normal' menu bar along the top, snug against the title bar. Thanks in advance for any advice.

• How to specify a web service URL within a Drupal module's simpletest?

  - by Matt V.

  I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

• Is php fileinfo sufficient to prevent upload of malicious files?

  - by Scarface

  Hey guys, I have searched around a bit, and have not really found a professional type response to how to have secure fileupload capability so I wanted to get the opinion of some of the experts on this site. I am currently allowing upload of mp3s and images, and while I am pretty confident in preventing xss and injection attacks on my site, I am not really familiar with fileupload security. I basically just use php fileinfo and check an array of accepted filetypes against the filetype. For images, there is the getimagesize function and some additional checks. As far as storing them, I just have a folder within my directory, because I want the users to be able to use the files. If anyone could give me some tips I would really appreciate it.

• MySql - only update some rows if the table exists - do not want an error thrown

  - by Pete Oakey

  I want to run an update query. The query will be run against multiple databases - not every database will have the table. I don't want the update to be attempted if the table does not exist. I don't want any error to be thrown - I just want the update to be ignored. Any ideas? EDIT: just to be clear - the query is executed in an automated deployment - no human interaction possible. EDIT2: the logic to say whether the update should run or not will need to be in the MySql query itself. This is not being run through a command prompt or batch or managed code.

• algorithm for checking addresses for matches?

  - by user151841

  I'm working on a survey program where people will be given promotional considerations the first time they fill out a survey. In a lot of scenarios, the only way we can stop people from cheating the system and getting a promotion they don't deserve is to check street address strings against each other. I was looking at using levenshtein distance to give me a number to measure similarity, and consider those below a certain threshold a duplicate. However, if someone were looking to game the system, they could easily write "S 5th St" instead of "South Fifth Street", and levenshtein would consider those strings to be very different. So then I was thinking to convert all strings to a 'standard address form' i.e. 'South' becomes 's', 'Fifth' becomes '5th', etc. Then I was thinking this is hopeless, and too much effort to get it working robustly. Is it? I'm working with PHP/MySql, so I have the limitations inherent in that system.

• Using unmanaged code, how can I find a type that has a given custom attribute assigned to it?

  - by Andrew

  I had thought I could enumerate the types using IMetaDataImport.EnumTypeDefs and for each of the tokens returned, call IMetaDataImport.EnumCustomAttributes. This works, in so much as I get an array of mdCustomAttribute tokens. Using these tokens I can get a metadata token representing the Type of the returned custom attribute, by calling IMetaDataImport.GetCustomAttributeProps. Comparing my results against ILDASM, I can see that this matches the "CustomAttribute Type" that ILDASM reports. However, I cannot work out how to determine the "CustomAttributeName" that ILDASM reports. This is what I really want! While I would be interested in knowing how to get the CustomAttributeName, I would settle for an alternate approach to solving the problem.

• How can I make sure the Sphinx daemon runs?

  - by Ethan

  I'm working on setting up a production server using CentOS 5.3, Apache, and Phusion Passenger (mod_rails). I have an app that uses the Sphinx search engine and the Thinking Sphinx gem. According to the Thinking Sphinx docs... If you actually want to search against the indexed data, then you’ll need Sphinx’s searchd daemon to be running. This can be controlled using the following tasks: rake thinking_sphinx:start rake ts:start rake thinking_sphinx:stop rake ts:stop What would be the best way to ensure that this takes place in production? I can deploy my app, then manually run rake thinking_sphinx:start, but I like to set things up so that if I have to bounce the server, everything will come back up. Should I put a call to that Rake task in an initializer? Or something in rc.local?

• Network Security and Encryption explained in laymen terms

  - by Ehrann Mehdan

  Although I might pretend very well that I known a thing about networks or security and it might help me pass an interview, or fix a bug, I don't really feel I'm fooling anyone. I'm looking for a laymen terms explanation of nowadays network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies" like me (e.g experienced Java developers that can speak the jargon but have no real clue what it means) Topics I have a weak notion about and want to understand better as a Java developer PGP Public / Private keys RSA / DES SSL and 2 way SSL (keystore / trustore) Protecting against Man in the middle fraud Digital Signature and Certificates Is there a resource out there that really explains it in a way that doesn't require a Cisco certificate / Linux lingo / know what is subnet masking or other plumbing skills?

• Internet and Intellisense bad for your memory?

  - by Barry Jones

  Having programmed for a while now I have noticed that I am becoming more and more reliant on the internet and intellisense to do my job. But I was wondering how much that has effected my knowledge over the past year or so. But does this matter? For example I am more likely now to remember that when I need to program against objects I have no knowledge about, I will go to the System.Reflection namespace and a quick look down the list will provide me with enough detail to get going again. But if you was to ask me which classes etc are required I would struggle to name them all. This problem of remembering seems to manifest itself more when going for interviews when people seem to focus more on the minute detail of obscure areas of the .NET framework and not on the wide and varied knowledge and experience of the applicant. Anyway I digress. Does anyone else think that maybe its time to turn of the intellisense and try and find better ways to learn, then quick fixes and work arounds of the internet?

• CRSF token and Session replication with Tomcat and Apache

  - by technocool

  I have an J2EE compliant web application. I use a session based token to append a secondary id to all incoming link generated by my application. To prevent my application against CSRF attack, I validate the secondary id before I allow the user session to work off the subsequent page. Recently, while working with session replication mechanism implementation, I observed that on session failover, the generated secodary id is lost and the user get re directed to the login page/default page. Any suggestions on how I can ensure that the my generated secondary token id is not lost from the replicated session?

• How can I generate a list of symbols used by a build product from a particular statically linked lib

  - by morechilli

  Say I have a visual studio project that builds a windows exe or dll from c++ source. The project statically links to several library (.lib) files. I would like to generate the subset of the available functionality in a particular .lib that the project actually links to. A very crude way to achieve this would be to remove the .lib from the linker input list. The error list on the build would then show me all the symbols that could not be found. Is there a better/proper way to generate this list, I'm happy with a solution that can be run as a custom build step in the project or one that runs against a built binary. I've looked at both the linker and dumpbin command line options but have not seen anything appropriate.

• how to search values in a dictionary that is assigned to a key for a PFObject without downloading all PFObjects of that class (iOS/Parse)

  - by mkc842

  Suppose I have a set of PFObjects (essentially dictionaries) of class "myObject". Objects of this class contain for key "myDictionary" a dictionary. "myDictionary", in turn, has a key "myKey" that I want to access and search for matches against "mySearchTerm". I don't want to download all myObject objects and then iterate through them to check myKey in each, because that would be very inefficient. I want to use a findObjects message to return just the matches. Is such a query possible? In other words, how can I search the values in a dictionary that is assigned to a key for a PFObject without downloading all PFObjects of that class? Here's what it might look like if there were a simple method for it, but I made up the containsKey part to clarify what I am contemplating: PFQuery *objectQuery = [PFQuery queryWithClassName:@"myObject"]; [objectQuery whereKey:@"myDictionary" ~containsKey~:@"myKey" equalTo:"mySearchTerm"];

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

  - by Grant McLean

  I've just been reworking my Encoding::FixLatin Perl module to handle overlong 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?

• authentication in PHP ?

  - by user296516

  Hi guys, I need to make an authentication script in php. I have already made a login.php page, where the user can enter his unsername/password and it gets checked against a database. If the unsername/password are correct, the user should be forwarded to members.php page together with a $_SERVER['username'] variable. What is the command in PHP to go to another webpage, in this case members.php ? in pseudocode I see it like this: if ( unsername/password are OK ) { $_SERVER['username'] = $username; goto(members.php); } Thanks!

• LINQ and paging with a DataTable - can't get Skip working?

  - by Kit Menke

  Ok so this might be a dumb question, but I can't seem to figure it out. I thought I'd try out LINQ against a DataTable. I got my query working and now I'm trying to implement some simple paging. DataTable dataTable = null; dataTable = GetAllDataTables(); var query = from r in dataTable.AsEnumerable() orderby r.Field<string>(Constants.fileName) select r; query.Skip(WPP_PAGE_SIZE * pageIndex).Take(WPP_PAGE_SIZE); My problem is that I get an error at query.Skip(...). Error 1 'System.Data.OrderedEnumerableRowCollection' does not contain a definition for 'Skip' and no extension method 'Skip' accepting a first argument of type 'System.Data.OrderedEnumerableRowCollection' could be found (are you missing a using directive or an assembly reference?) References I have: Microsoft.SharePoint System System.Core System.Data System.Data.DataSetExtensions System.Web System.Xml What am I missing?

• Excel 2003 - ADDRESS() function issues

  - by hairdresser-101

  I finally thought I had found a way to acutally use excel productively but the code that I followed does not appear to work. I'm thinking that the code is very limited and can't do what I want but I thought I'd ask to confirm - maybe it is my function that is the problem. I want to calculate the sum of a row of values for the previous month based on how many days we are into this month (i.e. It is the 20th of April so I want to sum the first 20 days of March to compare against.) =SUM(G4:ADDRESS(ROW(),7+$BR$3,4)) I basically want to SUM(G4:AA4) and have used the address function to return the cell reference AA4 by taking G4 and adding 20 to the column count. ADDRESS(ROW(),7+$BR$3,4) This successfully returns AA7 as expected HOWEVER, when I try to use the returning value in the SUM() function it throws an error... Am I not able to use this reference in my calculation?

• How can I make my search more broad?

  - by user1804952

  I created this search mysql string and it is to literal or maybe un-literal? If I search for Dave for example it will only find items like "Dave something" and not find Dave. $queryArtist = mysql_query("SELECT * FROM artists WHERE artist LIKE '%$ArtistNameSearch%' ORDER BY artist ASC"); I know mysql_query is out dated and will change it to mysqli soon as I get this worked out. Stuck here. An example of it no working is Example of search Could it be becasue the %20 space? I got it figured out, but it still does NOT find one direction or other things even those exist. here is what I have now $queryArtist = mysql_query("SELECT * FROM artists WHERE match(artist) against('$SafeSearchTerm' in boolean mode)");

• Using asp.net mvc model binders generically

  - by Sean Chambers

  I have a hierarchy of classes that all derive from a base type and the base type also implements an interface. What I'm wanting to do is have one controller to handle the management of the entire hierarchy (as the actions exposed via the controller is identical). That being said, I want to have the views have the type specific fields on it and the model binder to bind against a hidden field value. something like: <input type="text" name="model.DerivedTypeSpecificField" /> <input type="hidden" name="modelType" value="MyDerivedType" /> That being said, the asp.net mvc model binders seem to require the concrete type that they will be creating, because of that reason I would need to create a different controller for every derived type. Has anyone does this before or know how to manipulate the model binder to behave in this way? I could write my own model binder, but I'm not wanting anything past the basic model binding behavior of assign properties and building arrays on the target type. Thanks!

• Detecting GWT RichTextArea 'dirty' state

  - by David

  I want to detect when the contents of my GWT RichTextArea become 'dirty' (have been changed by the user) in order to enable a 'save' button accordingly. I suppose I could listen for key presses that are likely to have changed the contents; but browser support for key presses is notoriously quirky. I suppose I could, before editing begins, save the original contents in a variable, and upon key press, compare the current contents against that variable, but doing that on each key press is going to be really slow. Is there some neat way to achieve RichTextArea dirty-detection?

• Rails Multiple Table Inheritance question

  - by Tony

  I am starting to implement an MTI solution and have a basic question. I have 3 physical models - SMSNotifications, EmailNotifications, TwitterNotifications and they are subclasses of notification. At times in my code, I want to say Notifications.find(:all)so that I can get a set of results sorted by their creation time. Then I want to do things based on their subclass. What is the way to write Notifications.find(:all) and have Rails look through the subclass tables and combine the results? Right now Rails still thinks I have a physical Notifications table which goes against my MTI design. I am also considering the possibility that I should be using STI instead. I would probably have 10 empty columns per row but if getting all notifications requires a query for each type of notification, then I feel like this could be a big issue. Thanks!

• Testing a (big) collection retrieved from a db

  - by Bas

  I'm currently doing integration testing on a live database and I have the following sql statement: var date = DateTime.Parse("01-01-2010 20:30:00"); var result = datacontext.Repository<IObject>().Where(r => r.DateTime > date).First(); Assert.IsFalse(result.Finished); I need to test if the results retrieved from the statement, where the given date is less then the date of the object, have Finished set to False. I do not know how many results I get back and currently I'm getting the first object of the list and check if that object has Finished set to false. I know testing only the first item of the list is not valid testing, as a solution for that I could iterate through the list and check all items on Finished, but putting logic in a Test is kinda going against the concept of writing 'good' tests. So my question is: Does anyone have a good solution of how to properly test the results of this list?
