  • one variable and multiple controllers..

    - by Simon
    I'm working on a web application, using the CAKEPHP framework. Herefor i need to request one variable on multiple pages (all pages have different controllers). it is oubvious that i get a error on several pages, since the variable isn't declared in all the different controllers. Is there a workaround for this? i've already tried the app:: import to import a controller in another controller, but this doens't seem to work (still get a undefined variable error). Thnx for your cooperation! Regards, Simon

  • How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

    - by peace
    I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

  • MySQL – Introduction to User Defined Variables

    - by Pinal Dave
    MySQL supports user defined variables to have some data that can be used later part of your query. You can save a value to a variable using a SELECT statement and later you can access its value. Unlike other RDBMSs, you do not need to declare the data type for a variable. The data type is automatically assumed when you assign a value. A value can be assigned to a variable using a SET command as shown below SET @server_type:='MySQL'; When you above command is executed, the value, MySQL is assigned to the variable called @server_type. Now you can use this variable in the later part of the code. Suppose if you want to display the value, you can use SELECT statement. SELECT @server_type; The result is MySQL. Once the value is assigned it remains for the entire session until changed by the later statements. So unlike SQL Server, you do not need to have this as part the execution code every time. (Because in SQL Server, the variables are execution scoped and dropped after the execution). You can give column name as below SELECT @server_type AS server_type; You can also SELECT statement to DECLARE and SELECT the values for a variable. SELECT @message:='Welcome to MySQL' AS MESSAGE; The result is Message -------- Welcome to MySQL You can make use of variables to effectively apply many logics. One of the useful method is to generate the row number as shown in this post MySQL – Generating Row Number for Each Row using Variable.

  • Need help eliminating dead code paths and variables from C source code

    - by Anjum Kaiser
    I have a legacy C code on my hands, and I am given the task to filter dead/unused symbols and paths from it. Over the time there were many insertions and deletions, causing lots of unused symbols. I have identified many dead variables which were only being written to once or twice, but were never being read from. Both blackbox/whitebox/regression testing proved that dead code removal did not affected any procedures. (We have a comprehensive test-suite). But this removal was done only on a small part of code. Now I am looking for some way to automate this work. We rely on GCC to do the work. P.S. I'm interested in removing stuff like: variables which are being read just for the sake of reading from them. variables which are spread across multiple source files and only being written to. For example: file1.c: int i; file2.c: extern int i; .... i=x;

  • How should I group these variables?

    - by stariz77
    I have a shape that will be defined by: char s_type; char color; double height; double width; These variables are scanned in from a request string sent to my server and passed into my printing function, which then prints out the shape. Currently they are just local variables sitting in my main(); however, I was wondering if there would be any advantage in creating a struct containing these variables, and then passing the struct to my printing function? or how else might I improve my program's structure/style, would passing a struct by reference have any kind of performance benefit if there were many requests and therefore many printing function calls? printer(char st, char cr, double ht, double wd); int main() { // Other main functionality. char s_type; char color; double height; double width; sscanf (serv_req, "GET /%c/%c/%lf/%lf", &s_type, &color, &height, &width); printer(s_type, color, height, width); // Other main functionality. return 0; } It seemed "neater" if I had a struct or something that didn't leave me with declarations in the middle of everything else going on in main. I'm interested in structure/style as well as performance. EDIT: didn't mean to put printer declaration inside main.

  • What's the Benefit of Multiple Monitors

    - by DaveDev
    It's become apparent to me that in Software Development it's not uncommon to have more than 1 monitor. We've been pushing for multiple monitors here (currently I have 1 19") but it's difficult to get the point across to the 'deciders' that there would be a benefit. They're only concerned with saving cents. So I thought I'd ask around and see what software developers with multiple monitors thought? What are the benefits? What are the costs? What is the ideal number of monitors for a software developer? Thanks

  • Supporting multiple versions without separate builds in JavaME

    - by Casebash
    I want to be able to support multiple versions of Java ME without having to have multiple builds. I already know how to detect the profile/configuration/supported JSRs. My problem is that knowing whether the JSR is supported at run time doesn't allow me to use all the features. For if I call a function added in a later version anywhere in the code - even a location that will never be run, then this will be a compilation error due to static typing. Is there any way round this?

  • Uploading multiple files simultaneously with Flex

    - by David
    I have been working on a flex uploader, where the user can select multiple files. It works fine when the files are uploaded in a queue (one at a time), however as soon as I try to have it upload 2 files at once I run into issues. It seems that files will often lock up, and either stay at 1% until every other file is uploaded, or just not complete at all. There is never more than one file uploading at a time. Is there some issue with calling .upload on multiple files at once in Flex?

  • PHP email form multiple select

    - by Justin Goodman
    I'm trying to set up a simple PHP contact form for a website and I need some help modifying the PHP to list multiple items from a select menu and would appreciate the help. I'm a graphic designer, not a developer, so a lot of this is way over my head.

  • Multiple Questions per page using Drupal Quiz

    - by Andrew
    I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

  • Maximizing Adobe Air windows on multiple monitors

    - by Andrew
    In an Adobe Air AJAX application with multiple windows running on a system with multiple (three or more) monitors, can you maximize the windows in each monitor? I've seen posts by others trying to do this, but I've not seen anyone saying how it worked out. I basically need to build a 'status monitor' system (similar to, say, an airport departures monitor) in which there are public-facing displays that need to look and feel like single-purpose, embedded applications -- no window chrome and no visible desktop. I don't think this should be any different from any other windows application, but I don't know about Air. I have a dual-monitor Mac setup right now, but I can't easily test Windows and I likely will never be able to test three monitors at once. This application will be run as an AJAX Air application written in Aptana (or DW if it makes a difference).

  • Single database with multiple instances of Django

    - by jwesonga
    I have a Django project where the company will have a main site like www.ourcompany.org and a bunch of sub-domains like project.ourcompany.org. Content appearing in the sub-domains like case studies should also appear in the main site. I've decided to use multiple instances of Django BUT one database for each sub-domain so that I can have some flexibility and take advantage of the Sites framework. What I'm not sure of is how to access the models across the multiple instances. If I have a model: class CaseStudy(models.Model): title=models.CharField(max_length=100) site=models.ManyToMany(Site) Do I need to create this model in every instance so that I can have access to the object?

  • Inheriting from multiple classes in Java (and possibly not using interface)

    - by sheidaei
    So, let's say we have classes A, B and C and I want to inherit from all those classes and have another class called D, it can be done using implements and interfaces in Java. But let's say we don't want to use this simple solution, would you be able to inherit class D from classes A, B and C in any other way in Java? (This question might be related to design patterns, it has been brought up after challenging my colleague at lunch discussing design patterns) I don't think there is any other way to have multiple inheritance in Java other than using multiple interfaces.

  • Django - User account with multiple identities

    - by Scott Willman
    Synopsis: Each User account has a UserProfile to hold extended info like phone numbers, addresses, etc. Then, a User account can have multiple Identities. There are multiple types of identities that hold different types of information. The structure would be like so: User |<-FK- UserProfile | |<-FK- IdentityType1 |<-FK- IdentityType1 |<-FK- IdentityType2 |<-FK- IdentityType3 (current) |<-FK- IdentityType3 |<-FK- IdentityType3 The User account can be connected to n number of Identities of different types but can only use one Identity at a time. Seemingly, the Django way would be to collect all of the connected identities (user.IdentityType1_set.select_related()) into a QuerySet and then check each one for some kind of 'current' field. Question: Can anyone think of a better way to select the 'current' marked Identity than doing three DB queries (one for each IdentityType)?

  • How to launch new Firefox window with multiple tabs using Python

    - by newbie py
    Hi, I want to create a MSWindows Python program that would launch a new Firefox window with multiple tabs each time it is run. For example if I want to search "hello", a new window pops out (even if a Firefox window is already open) and then launches a Google and Bing tabs searching for "hello". If I change the keyword to "world", a new browser pops out again with Google and Bing tabs searching for "world". I've looked at the webbrowser module but couldn't get it to: 1. Launch a new browser when a browser is already open: e.g. webbrowser.open('http://www.google.com',new=1) will instead open a new tab 2. Launch multiple tabs simultaneously in the same window Appreciate the help. Thanks.

  • Tip 16 : Open Multiple Documents within Single Application Instance Using C#

    - by StanleyGu
    1.       Using Microsoft Word 2007 as an example, you can open test1.docx and test2.docx at same time. The two documents are opened within single instance of the word application. World application supports command line argument of passing multiple documents. 2.       Again, Using Microsoft Word 2007 as an example, you can open test1.docx first and then test2.docx. The two documents are opened within single instance of the Word application. Word application supports Multiple Document Interface (MDI). 3.       Using Notepad as an example, you receive error message of “The filename, directory name, or volume label syntax is incorrect” if you want to open two documents at the same time. Notepad does not support command line argument of passing multiple documents 4.       Again, using Notepad as an example, you can open test1.txt first and then test2.txt. The two documents are opened to two different instances of Notepad application. Notepad does not support Multiple Document Interface (MDI). 5.       In conclusion, there is nothing you can do trying to rely on System.Diagnostics.Process class to open multiple documents within a single instance of an application because it is controlled by the application itself. The best approach is to read any developer or user guide of the application and make sure: 1. The application supports Multiple Document Interface (MDI) 2. The application provides command line argument of passing multiple documents. Then, you can use Process class and the command line argument syntax to open multiple documents for the application.

  • How do I configure multiple domain names on my IIS server? [closed]

    - by Dillie-O
    We have a few websites that we are running on one instance of IIS that need to be mapped for each of their domain names. For example. Site A has the domain name coolness.com Site B has the domain name 6to8Weeks.com Site C has the domain name PhatTech.com When I look at the "Web Site Identification" section of the IIS configuration window, I notice that I can specify an IP address and port, but if I click the Advanced button, I can also configure the site based on host header values as well. How do I configure each site in IIS? Ideally I would like them to all be able to listen to port 80, so I don't have weird URLs, but I'm not sure if I do this using headers, IP addresses, both, or something else.

  • Is it better to have multiple domains for cities or one single TLD?

    - by Brett
    I make websites for small businesses, and for some reason business owners love to have several domains with the same website but the TLD containing the city name. For example: 1. smallbizname.com 2. clevelandsmallbizname.com 3. columbussmallbizname.com 4. cincinnatismallbizname.com ... and so on. I've seen questions about localization per country aspects, but this is a much smaller scale, so I don't think the same rules apply. The problem I have is the companies never want to write separate content per domain, just have the same website hosted several times at each domain. I feel this probably hurts SEO for two reasons: 1. Traffic gets scattered throughout domains, could be boosting just one domain. 2. Duplicate content penalty because the content is identical. My question boils down to this... Should I redirect all the city domains to the main business name domain, or does having these separate sites help to rank better per city? And if they are redirected, how does google rank the redirects? Thanks for any input on this issue!!
