Web Applications





Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.

Just saw an article on Winn-Dixie losing court battle dealing with their website and lack of being fully accessible to the disabled. Conclusion to the case was websites will need to conform to WCAG 2.0 standards. Our company operates 3 websites, all on the Shopify platform. I have been given the task to find out if we are compliant.  I downloaded the NVDA screen reader and all three sites were compatible with that, as well as a Mac screen reader. My question...anyone dealing with this and what tips or advice can you supply to assist in the matter ?  Is there an official "checklist" ?  Thanks in advance, I am sure we will be hearing more about requirements and potential lawsuits soon enough.
I had this question after viewing delphi intraweb upload file.

I have an Intraweb app  (Delphi XE4) which successfully uses IWFileUploader. User can upload a file to the application's dedicated folder if they access the app via a windows pc.

Problem is that one of the users has a Samsung Android tablet which they use to access the web application, and IWFileUploader doesn't work.
Ideally they'd be able to take a photo with the tablet, and upload it to the Intraweb app's web directory.

Is this even possible?

My volunteer group needs help finding a free or low cost way to create a website that would allow us:
1. to have a membership section that is private,
2. would allow each member to post what volunteer project they need help with and,
3. then have each member of the group automatically receive an email requesting help with the project
I hope someone can help me with this.

I am testing on the Network Load Balancing feature in order to load balance & failover web applications hosted on 2 servers. Locally I could access the web applications using the cluster IP address & cluster name. But I’m unable to access them via publicly using a typical ADSL internet connection. Ports for the web applications are opened in the ADSL router for the cluster IP address. Via publicly, accessing the web applications hosted on a single server works fine. What am I missing here?
I am actually trying to implement text-to-speech conversion in Salesforce by hitting a third-party api.

When i send the request through Postman, i get back the proper response in .wav format. However, I'm not being able to handle this reponse programatically in salesforce end, as I am not able to store the response in any audio object.

Any assistance would be greatly appreciated.

Thanks in advance.
Wordpress website - need Time Sheet/Time Card page - Wordpress plugin? Gravity Forms?

Our small company really needs help with this! We have a Wordpress website and have purchased the paid version of Gravity Forms,
but we need any kind of Plug in solutions that can do:

1) A bi-monthly Time Card. With 14 rows, Date, Job, Start Time, Stop Time and Total Hours Fields.
2) Possibly have it emailed or Gravity Form -> to PDF, then emailed.

3) However we have hundreds of remote employees, so it needs to be easy to view and possibly print (but not print one by one, but batch printed).

4) Gravity Forms or any other Wordpress Plug-in that can accomplish this...

The Boss is willing to pay to have this done.

Thank you so much!
i want to implement something like this http://opensoul.org/2011/06/23/live-search-with-knockoutjs/

into my page that uses the google maps api, so that you may search through the map markers

jfiddle model of my page:

but my problem comes from the page also needing google maps info windows and i am very new to js and knockout so i am unsure as to how i would add info windows to my knockout objects so that my map markers will still be search able.

link to google maps info windows page: developers.google.com/maps/documentation/javascript/inf‌​owindows
Hi Experts,

Hopefully you can help with a very bizarre issue
We noticed an issue with what we originally thought was the fault of our load balancers, where the site would go down, and be marked down by the LB, but when you attempt to browse directly to the server itself, the page would return.

A bit of investigation later, it appears to be a local problem on the web servers itself. Monitoring using wireshark, we could see the LB making the a health check (using a GET request to the URL), and the server delaying its response for an extended time, causing the health check to fail.

However, new requests coming from other IP's the web server responded to immediately

Does anyone know why this may occur?

The servers in question are Windows 2016 x64

Hello expert,
I am doing migrate from ASP NET MVC 5, net fw 4.6  to ASP NET CORE fw NetCoreApp 1.1.

The type 'Enum' is defined in an assembly that is not referenced. You must add a reference to assembly 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'

The type 'DateTime' is defined in an assembly that is not referenced. You must add a reference to assembly 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'

I guess all kind of this error derived from assembly incompatible, anybody know how to fix this issue?
I did add nuget Microsoft.NETCore.Portable.Compatibility but no help.

I am having a serious issue routing our MVC 5 application to an external URL subdomain using our ISP GoDaddy.

I have several websites ASP.net, third party application that I host internally on IIS on a private server 192.168.*.* these applications are NAT in my firewall to public ip address on our comcast network 50.202.*.*. We host our domain at GOdaddy and were able to route the NATed ip to subdomain webpage.mydomain.com....we have been using this technique for years and we resolve external url's using subdomain.mydomain.com.  On our internal dns I have webserver 192.168.*.* A record to www so we are able to route internally www.mydomain.com/webpage. The issue I am having is with the MVC 5 application which is published to the same web server I am able to access internally www.mydomain.com/webpage but we cannot access externally webpage.mydomain.com we can only access by      

I have the same NAT because it is on the same webserver/IIS, I setup the subdomain in Godaddy and the http://publicipaddress/webpage works for MVC application but, not the webpage.mydomain.com. I have been working with the programmer and verified all IIS settings, I verified DNS settings with GoDaddy technician, but my programmer is still only using the default rout in the MVC application. Everything I have read so far which there are multiple ways of doing this says we need to add the webpage.mydomain.com into the MVC application routing table. Is there anyone …
I want that the URL displayed in the Browser should be scrambled for the user (So they cannot just change a number/string to try to get access to another record in website).

I wanted to do this URL scrambling using IIS transparently and not the hosted application.

Is there any way to do that?

I'm looking for a way to nest array formula in google sheets, but not in one cell. I want to split complex formulae into more than one cell to improve readability, and in some cases to avoid repetition. Is there a way to do this? See example:


Cells A1:C8 contain the raw data, which i can query, eg =query(A1:C8,"SELECT * WHERE C='citrus'")

Cell E1 contains a filter of this data  =filter(A1:C8,A1:A8>4)

I would like to be able to query the filtered data without specifying the dimension of the filtered output.

I can do this by nesting in one formula: =query(filter(A1:C8,A1:A8>4),"SELECT * WHERE Col3='citrus'")  

But is there a way to do this without copying the whole formula into one cell? i.e.
=query(** whatever array is specified by cell E1** ,"SELECT * WHERE Col3='citrus'")  


The example given is a little contrived, here is a more relevant example: https://www.experts-exchange.com/questions/29005691/Natural-SQL-in-google-sheets-by-substituting-column-names-for-column-letters.html
I want to build Laravel based CMS with following requirements:

1. Multi-sites (running on sub-domains, manage own database) each with API access.
2. Admin (manage all sites/database).
3. Same Codebase (can be replicated if needed).
4. Same Database with different data for each site.

Can someone guide me how to develop such system using Laravel 5.4.

I know there are some packages that I can use i.e
Multi Tenant Laravel

This package create separate database/tables for each site, which I think makes problem for me to create single super admin.

Any thoughts?
