• Comparing form fields with data base fields and highlighting the form fields

  - by naveen kotla

  Hi, Can you help me in the following two scenarios (PHP+MYSQL) Scenario1: I need to compare the HTML Form field values with the Database field values and highlight the form fields in some color whose values are different from database values before submitting the form (to alert the user). Scenario2: On loading the form, i need to compare the values present in 2 different database tables (tables are having different column names but the information is same). the fields which are not same needs to be highlighted in the html form to indicate the users that the master data is varying from secondary data. Could you help me which is the efficient way of doing this (comparison and highlighting the form values). thanks in advance Naveen

• Cannot change font size in Tk

  - by FireAphis

  Hello, I'm trying, for the first time, to create a GUI in Ruby using Tk. I've copied a code snippet from one of the numerous web tutorials and try to change the font for one of the labels, but nothing seems to affect how the text is presented. Here's the code: require 'tk' root = TkRoot.new('title'=>'MCIS') defaultFont = TkFont.new("weight"=>'bold', "size"=>20) Lbl = TkLabel.new(root) do text "Boooo" borderwidth 5 font defaultFont foreground "red" relief "groove" grid('column'=>3, 'row'=>0) end Tk.mainloop() I see the effects of all the parameters of the label but not the font. I've tried to change the size, the weight, give different family names, leave just one parameter; nothing works - the font stays default as it was. Surprisingly it doesn't report any errors, everything looks fine. Maybe it's versions problem? I run these: Linux Centos 5 Tk 8.4.13 Ruby 1.8.5 ruby-tcltk 1.8.5 Also, don't know if it is important, I ran it via Xming from WinXP machine.

• Facebook Graph API - authorization types?

  - by Alex Cook

  I'm struggling with the new Facebook Graph API, perhaps someone here can help. Here is what I want to do: provide a ‘login w/ FB’ button, throw to /authorize, get a code, throw to /access_token, get an access_token, and be able to hit https://graph.facebook.com/me for info about the user. When I try to use type=client_cred in the /authorize call, I get an access_token that lets me hit URLs with userIDs or names, but not /me. I receive an error stating I need a valid token. If I can't hit /me, how do I figure out who the current user is? What exactly should I use in the type param if I want a website to access a users data? I've seen posts with type=web_server, etc, but I can't seem to find a sure fire way to do, what I think, is pretty simple... Thanks ahead of time for any help thats provided...

• How do I create sub-applications in Django?

  - by jamida

  I'm a Django newbie, but fairly experienced at programming. I have a set of related applications that I'd like to group into a sub-application but can not figure out how to get manage.py to do this for me. Ideally I'll end up with a structure like: project/ app/ subapp1/ subapp2/ I've tried: manage.py startapp app.subapp1 manage.py startapp app/subapp1 but this tells me that / and . are invalid characters for app names I've tried changing into the app directory and running ../manage.py subapp1 but that makes supapp1 at the top level. NOTE, I'm not trying to directly make a stand-alone application. I'm trying to do all this from within a project.

• Colour Name to RGB/Hex/HSL/HSV etc

  - by Abs

  Hello all, I have come across this great function/command. Colour to RGB, you can do this: col2rgb("peachpuff") //returns hex It will return one hex value. I want to extend this using Perl, Python or PHP but I want to be able to pass in, for example, "yellow" and the function returns all types of yellows - their hex/rgb/?/etc value. I already have a quick solution implemented, which involves mapping colour names to hex values but now I want to get more precise and use some formulas etc to determine what's what. However, as usual, I don't have a clue on how to do this! So I appreciate any implementation advice on how to do this. Thanks all

• How to use PDFBox 1.0 in .net / C# environment using IKVM

  - by Evan

  Id like to use PDFBox to generate PDF highlight files in my .net project. PDFBox states that it can be used in .net via IKVM http://www.pdfbox.org/userguide/dot_net.html BUT running ikvmc (latest version) to generate the DLLs on PDFBOX.1.0.0.jar generates a whole lot of NoClassDefFound warnings. How should I fix this, and what other DLLs do I need to include in my project? It seems as though file names have changed from the older documentation/articles I have read on the matter. thanks in advance.

• CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

  - by Rasiel

  I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

• Creating a user-defined code generation system in PHP

  - by user270766

  My newest project that I'm looking to build with CodeIgniter would require some sort of system that would allow a user to drag and drop pre-defined functions/methods into mini-classes/objects and then run/test them in the browser. So it'd something similar to Scratch. I've designed a relational database that I think could work for this (storing the function names and have these classes "subscribe" to those functions) - but I'm wondering whether or not to go ahead with it. Is there a better way to do this or is there a system out there that would accomplish this for me? EDIT: It would have to be extremely simple for an end user, but hopefully be flexible enough to easily add more complex functionality in the future.

• How to represent "options" for my plugin architecture (C# .NET WinForms)

  - by Joshua

  Okay basically here's where I'm at. I have a list of PropertyDescriptor objects. These describe the custom "Options" fields on my Plugins, aka: public class MyPlugin : PluginAbstract, IPlugin { [PluginOption("This controls the color of blah blah blah")] [DefaultValue(Color.Red)] public Color TheColor { get; set; } [PluginOption("The number of blah blah blahs")] [DefaultValue(10)] public int BlahBlahBlahs { get; set; } } So I did all the hard parts: I have all the descriptions, default values, names and types of these custom "plugin options". MY QUESTION IS: When a user loads a plugin, how should I represent these options for them to config? On the back end I'll be using XML for the config, so that's not what I'm asking. I'm asking on the front end: What kind of WinForms control should I use to let users configure the options of a plugin, when there will be an unknown amount of options and different types used etc.?

• PHP splitting arrays into groups based on one field's value

  - by Dan

  I have an array containing arrays of names and other details, in alphabetical order. Each array includes the first letter associated with the name.

• How to store Ruby method references in a database?

  - by Mad Wombat

  I am writing my first rails app. It needs to aggregate some data from multiple sites and for each site I have a unique way of getting the data (some provide RSS, some JSON, for some I scrape the HTML etc.). These will run on schedule, probably as a rake task from cron. It seems logical to store the sites and relevant information in a model, but I am not sure where to put unique data retrieval methods. Do I store method names in the model? Do I just name the methods the same as site name and call them that way? Basically, I need a way to read a list of sites and call appropriate method for each site. What is the Ruby on Rails way to do it?

• Can I use a class as an object in C# to create instances of that class?

  - by Troy

  I'm writing a fairly uncomplicated program which can "connect" to several different types of data sources including text files and various databases. I've decided to implement each of these connection types as a class inherited from an interface I called iConnection. So, for example, I have TextConnection, MySQLConnection, &c... as classes. In another static class I've got a dictionary with human-readable names for these connections as keys. For the value of each dictionary entry, I want the class itself. That way, I can do things like: newConnection = new dict[connectionTypeString](); Is there a way to do something like this? I'm fairly new to C# so I'd appreciate any help.

• OpenGL|ES on a desktop PC.

  - by almb

  I'm working on a OpenGL project that I would like to port to embedded systems that support OpenGL|ES. Since OpenGL|ES is a subset of OpenGL how hard would it be to compile my OpenGL application on an embedded system? (Assuming that my OpenGL code is in the limits of OpenGL|ES) I guess what I'm wondering is: is it possible to dircetly wrap my OpenGL calls with MACROS to make it compatible with OpenGL|ES API call names? Are there any calls specific to OpenGL|ES that I would have to implement? Sorry, if I'm not clear. Thank you.

• MySQL SELECT MAX multiple tables : foreach parent return eldest son's picture

  - by Guillermo

  **Table parent** parentId | name **Table children** childId | parentId | pictureId | age **Table childrenPictures** pictureId | imgUrl no i would like to return all parent names with their eldest son's picture (only return parents that have children, and only consider children that have pictures) so i thought of something like : SELECT c.childId AS childId, p.name AS parentName, cp.imgUrl AS imgUrl, MAX(c.age) AS age FROM parent AS p RIGHT JOIN children AS c ON (p.parentId = c.parentId) RIGHT JOIN childrenPictures AS cp ON (c.pictureId = cp.pictureId)) GROUP BY p.name This query will return each parent's eldest son's age, but the childId will not correspond to the eldest sons id, so the output does not show the right sons picture. Well if anyone has a hint i'd appreciate very much Thank you very much, G

• How do I change my iPhone App binary filename

  - by Kamchatka

  I get the following error when I try to upload the application on iTunes Connect: "Binary file names cannot contain a space. Please rename your binary file and try again." If I try to Validate the Application in XCode, I get: "My Application.ipa: filename may not contain whitespace" So I guess I have to find a way to rename this .ipa file. I don't want to change my product name which has to stay "My Application". How can I do that? Thanks!

• Good freeware COM/ActiveX Type Library Explorer?

  - by Tomalak

  I used to have a dated, but valuable solution to display COM/ActiveX control- and type-library contents (ProgIDs, method names and signatures, enumerations, constants, interfaces/coclasses, etc.) of all such libraries registered on my system. It provided an Explorer-like overview of everything that was available to ActiveX development/scripting and served as an automatic API documentation tool since official docs for most COM/ActiveX libraries are either missing completely or fragmentary at best. My recent move to a 64bit Windows rendered the program I had unusable, due to internal dependencies on the 32bit VB6 runtime (comctl32.ocx) that is no longer supported on 64bit Windows. Does anyone know an alternative that still works?

• Trouble with MySQL: CONCAT_WS(' ', name_first, name_middle, name_last) like '%keyword%'

  - by AJB

  hey folks, I'm setting up a keyword search across multiple fields: name_first, name_middle, name_last but I'm not getting the results I'd like. Here's the query: "SELECT accounts_users.user_ID, users.name_first, users.name_middle, users.name_last, users.company FROM accounts_users, users WHERE accounts_users.account_ID = '$account_ID' AND accounts_users.user_ID = users.id AND CONCAT_WS(' ', users.name_first, users.name_middle, users.name_last) LIKE '$user_keyword%' ORDER BY users.name_first ASC" So, if I've got three names in the DB: Aaron J Ban Aaron J Can Bob L Lawblaw And if the user_keyword == "bob lawblaw" I get no result. If user_keyword == "bob L" then it returns Bob L Lawblaw. Obviously I can't force people to include the persons middle name in their keyword search but I'm stuck for the proper way to do this. All help is greatly appreciated.

• Linked servers SQLNCLI problem. "No transaction is active"

  - by Felipe Fiali

  Im trying to execute a stored procedure and simply insert its results in a temporary table, and I'm getting the following message: The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "MyServerName" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "MyServerName" returned message "No transaction is active.". My query looks like this: INSERT INTO #TABLE EXEC MyServerName.MyDatabase.dbo.MyStoredProcedure Param1, Param2, Param3 Exact column number, names, the problem is not the result. MSDTC is allowed and started in both computers, Remote procedure calling too. The machines are not in the same domain, but I can execute remote queries from my machine and get the result. I can even execute the stored procedure and see its results, I just can't insert it in another table. Help, please? :)
