I have been watching tutorials and looking/researching and I can't find anywhere how to create an array of image urls.
I am trying to use the framework SDWebImage. All the tutorials that I have been looking at do exactly what I need my app to do, but with a TableView not a normal ViewController. I also would like to have it where you push a button and then it will randomly call one of the images. The urls are from the images stored in Firebase Storage. This framework (SDWebImage) is really what I want to use because it does exactly what I want to do and makes it really quick and easy. The tutorial that was closest to what I am doing is except for Jared has his in a TableView. This video is exactly what I want meaning the way he did his code like that. I really like his tutorials and his code is nice.
Overview: I need a random image from the array to load right when the app is launched, and when you click the button I need it to load another random image. I looked into this framework because at the moment I will have 400 images and more coming in the future and it is super easy to do exactly what I want.
Please help me I have been searching for 2 days and I have no idea what to do! I know this is a pretty simple concept for having an array and for using this normal ViewController instead of a TableVIew.
All help is gladly appreciated.
According to the SDWebImage documentation, you can use the setImageWithURL to set each image view inside a cell set. That code can look something like this:
self.imageView.sd_setImageWithURL(url, completed: block)
I don't know if this is exactly what you are looking for! To get better answers from Stack Overflow it's always better to post segments of your code that are not working, with an explanation of what you have tried and what errors you are getting. See here for some tips on asking good Stack Overflow questions, and here for some types of questions you should avoid.
Hope it helps!

I would like to build a service that can manage large dataset by grid view. It's similar to Excel or Google's Spreadsheet. The service can render and modify directly on the grid view.
I would like to use react or some latest technology to develop the front-end. I found a react component named react-virtualized.
I still wonder that can it implement modification functionality on it.
Could you explain me more about how it work or under the hood ? Actually i need some idea to propose the solution like this.
Could i use react-virtualized for rendering and modifying large tabular data?
Yes.
Sounds like you're looking to build something like this. It is built with react-virtualized and the source code for it can be found here.

This question is a bit too vague for Stack Overflow I think. You might find this talk informative since it kind of covers the basics of react-virtualized. After that I would suggest browsing the documentation.
Once you have a foundation then more specific questions could be directed here or to the react-virtualized Slack channel.
First of all I would like to thank everyone on this forum, as you have made some of my friends greatest projects successful and I was hoping one of these projects can be done without them.
Now I want to expand to other services. I want to make an app in WinForms or WPF (But im still learning XAML so if you can it would help to answer for winforms) that constantly updates data and displays pictures or video in a row/rows. Like almost Moviebox for iPhone or Showbox for android. How movies are updated constantly without updating the app. (Im not promting piracy, its just the best example I could think of). And when you click on the movie(Which is a picture) it gives a description and picture and even a youtube video.
It kinda would work like a blog reader.... I think?
I think I will need a server and I will probably need a database. But sadly , i'm still a beginner, but willing to learn. Thanks and if you need any more info, please just ask. :)

I'm attempting to learn a bit more about out how grid filtering works in Extjs.
I'm using the example that comes with the JS 4 download, i.e.
http://docs.sencha.com/ext-js/4-0/#!/example/grid-filtering/grid-filter-local.html
I can run it on my local server such that it displays the grid outline (with filter options in the column headers), but no data gets loaded at all. I was hoping that I could just use the local flag with the accompanying JSON file without the need to get involved with the SQLlite aspects, for a start.
I can't figure out why the JSON data isn't loading though. Any help, hints or tips would be much appreciated. I've spent ages on this, looking at other examples, both via here, Google and the Sencha website.
Mark as complete (see above) though I don't know detail on why it's started working.
I want to create modules for my content types. Looking over the drupal field api as well as some examples of creating content types programmatically, i have a basic module. But theres a few things I can't seem to get working.
On text_with_summary, I have no idea how to set the number of rows, and how to set it so it actually has the summary. I've tried numerous settings in my code, and my field still has 20 rows, and the summary is unchecked. Be happy if anyone can even point me toward some good examples.
I tend to look at the examples modules when trying to learn.

I want to know how is the Mozenda Screen Scraper coded?
http://www.mozenda.com/screen-scraper
I shows a browser where user can select the fields he wants to scrap and it creates a crawl script out of it.
The crawl script generation part is clear to me, I want to know does it record the user actions which the user is doing in the browser.
I want to do something similar using C#.
I guess they run something like iMacros on the backend. I even noticed the iMacros browser icon in some of their screenshots ;-)
If you want to code something like this yourself in C#, the IE webbrowser control is the best starting point!
#yc08m, I can tell you for sure that they are not using iMacros. It is all coded with their own proprietary code.
I realize this is an extremely outdated post, but they seem to rely heavily on XPath, so first things first you would need to load the page into an object that you can query. I'd recommend using something like Html Agility pack to accomplish this.
