I have a google sheet case in my project and I want from my application to listen for data change on spreadsheet changes and change it somewhere else.
Is it any way to do that with the official API of google?
Also, I see the below link and I think it's for javascript cases, is there any way to do this on c#?
https://developers.google.com/apps-script/guides/triggers/events
To start with Push notifications , you will use the Files: watch method to start watching for changes to a file.
Regarding your question, is there any way to do this on c#?
Yes and you can find an example of how to authenticate and authorize your app to make calls to the Drive API.

Is there a way to programatically upload an image file to search in Google, and then downloading the first one (the one with best resolution)?
EDIT: The Google Search API would not work for me, as I would have much more than 100 requests per day, and I am not willing to pay, since I am not a company
Yes, there is. The Google Custom Search API allows you to submit queries (including images) and retrieve results programmatically. There are even client libraries available for multiple languages.
EDIT: After OP changed his question, basically saying that he doesn't want to use the Google API, I can only refer to this(a bit outdated) question and quote the Google Terms of Service:
1.4 Appropriate Conduct. You shall not, and shall not allow any third party to: ... (i) directly or indirectly generate queries, or
impressions of or clicks on Results, through any automated, deceptive,
fraudulent or other invalid means (including, but not limited to,
click spam, robots, macro programs, and Internet agents);
So to recap, it is possible, but it is only legal via the API I linked above.
I'm developing a web (using asp.net and c#) which has a FileUpload control from asp.net. The upload thing works perfect and as far as I know I can't show progress data (%, bytes transfered, upload speed, time elapsed, time left, progress bar) using the FileUpload control from asp.net because its not asyncrhonous.
I've searched a lot (really) on the internet and I didn't find what i'm looking for and too much info has become a big confusion since I'm not sure about what I have to use.
On my web page I have a file named "UploadFile.aspx" which has a FileUpload control and a button that handles the uploading. On code-behind (UploadFile.aspx.cs) I have all the server-side logic (Upload the file into specific folder, store info about that file into a database, etc. etc) and I don't want to change this.
What I need to know is how to show the progress data to the user while is uploading the file? I can't use 3rd party applications because this is for an important commercial site. It's not a problem for me if I have to learn javascript / jQuery / Whatever but really i'm a bit lost and I don't know how to start.
Thanks for your time and your help guys.
There's some pretty cool solutions out there. Granted, you can code your own, but I'd suggest using a jQuery plugin like Plupload. If you need help setting it up, you can read their documentation.
There are lots of lots of demo code are available on the net to show the progress bar with file upload control in c#, most of them work fine on Local system but never work on the live server, Because You CAN'T USE A FileUpload control for what you want to do. When a user POSTs a file, you have to think of it like a querystring parameter. It goes as one Http Request. If you want to do a progress bar you'll want to look into something that can interact with the server asynchronously.
If you don't want to use any 3rd party that relies on Flash / Html 5, please take a look at this article:
http://vanacosmin.ro/Articles/Read/AjaxFileUpload
This is possible (and if you're using .NET 4.5 GetBufferedInputStream will make your life easier), but it is not very easy, as you'll see.
Basically, if you want a file upload with progress bar that is fully compatible with every browser, you need to handle this server side and give an url where the client (the browser) can check periodically for the progress with ajax.
I'm working on a program in Visual C#.NET and I need some help.
I need it to be able to take in some text through a text box, then somehow send that text to google, and bring back the resulting URLs (not the full results, just the URLs) and then display those in my program. How would I do that?
Use the WebClient class to send the query to Google and read the response.
Alternatively, use a .NET library that interacts with the Google search API, like this one (this was just the first Google result).
There are also REST libraries for .NET, if you go with the newer custom search.
Unfortunately the Google Web Search API is deprecated and no longer available. However the next best thing IMO is Google Custom Search Engine.
I've got a site which produces charts such as the one below
I'd like to encourage visitors to embed the generated graphic on their own sites and blogs. Is it possible to include views for that chart in google Analytics? I want to be able to see when a site embeds the image so that it's tracked in the analytics reports.
I'd envision some API that I can call from the server-side method which generates the PNG, but haven't been able to find anything specific.
Thanks!
This is indeed possible, have a look at the Google Analytics for Mobile Websites documentation. This details how to build a request to google analytics on the server, with quite a few different code samples (C# included).
While this documentation revolves around tracking page views, this concept could be extended to other types of activity you can record in google analytics, such as Events. In your specific situation I think I would want to setup the view of the chart as an Event, as this will not 'mess up' your true traffic (though you could use an advanced segment to exclude the chart traffic if you chose to register them as page views).
The documentation for event tracking is available here. Looking through it should give you a good idea of how you could express viewing your charts. Once you got an idea of how you wanted to track the event in GA, write the javascript and then view the URL (beacon) it generates to send the information to google. You'll be able to use that as a template to send event information from the server.
In regards to actually serving the image, you have a lot of options. If you app is written in MVC, look at the FileResult class (and the asssociated File() method available on the Controller class). If you working in a Webforms app, you will be using a Response.WriteFile() or something to that affect. This wrox article has an example of the idea behind this. The example is for creating a no leaching / hotlinking image handler, but the concept of writing an image to the HttpReponse is the same.
We all know that it is possible to "open" a Word document (or file from any arbitrary application) by clicking on a website link and then clicking the Open button.
I also know that, if I want to upload an application document to a web server, I must first save the document to my computer, and then go to an upload page, click a file/open button, find my saved file and upload it.
But is it possible to save a document to a website location or Url, effectively skipping the first save step and uploading the file to the web server through the Save dialog of the application, directly?
How would this be done in ASP.NET MVC?
It really depends on how complex you want to make it. This is pretty much what "web folders" offered (via WebDAV), but in general it creates more problems than it will ever fix. I don't recommend this approach.
Your best bet to make this simple is a dedicated client app - perhaps (although this is a dubious example) how Office talks to sharepoint. In a simpler example, you could create a silverlight out-of-browser application that saved via a web-service to a site using WCF or similar.
I think there is some creedence in what #Marc says. Personally I'd probably map a drive to the web site in question, if that's possible, and have a folder to upload to.
Then I'd have .Net check changes to the folder and take those files and import them into the repository, whatever that may be.
It's still an imperfect solution and I'm not sure there is a correct solution as yet.
I guess you could always write, and I can't believe I'm writing this, macros to save to the ftp location.
I'd guess you have a few choices, in no particular order:
Web service that the application can reference and upload through.
REST service (WCF or otherwise) that the application can POST to.
HttpHandler or MVC controller action that the application can POST to.
WebDAV directly to the server.
Number 3 sounds like it's closest to what you were looking for ("How would this be done in ASP.NET MVC?"). Scott Hanselman has a good article on handling file uploads in MVC on his blog.
When you implement the client, there's a little bit of a trick to that, too, since you can't just POST like usual; you have to post in multipart/form-data format. I posted a blog entry with some sample code on how to do that.
