I have found some examples but not really good working anymore.
I hope somebody can help me out!

How can I capture URL parameters sent to a google form, and save them to the connected spreadsheet?

I have 2 scripts - one to fire on open trigger, and one to fire on save, I'm not sure which one would work best with function scope etc...
But basically, users are sent to the survey form using a public link, and additional info is added to that link in the form of parameters/queries, such as:
booking=123456
start-at=1429952400
item=1702
I'm trying to have the script save these parameters, or even the entire URL that was used to open the form, preferably on the same row as the survey response, but even if the user doesn't submit the form, I would still like to save the URL as a non-completed survey (hence the on-open and on-save triggers).
I looked into:
function doGet(e) {},
function URL(text) {},
function doPost(e) {},
even console.log(params); and console.log(e);
as well as others and I cannot seem to get access to the URL.
What gives? Should I just code this on my own server and run my own form? I would really like to figure out google scripting but it seems just too cumbersome at this point. Any help or solution would be highly appreciated.
To be clear, I don't think I can use a pre-filled url, because I don't know that parameter values ahead of time, and I don't think you can use hidden fields for pre-filled anyway.

A prefilled-url could be used to set the answers to all the questions in a Google Form.
Please bear in mind that Google Forms doesn't support hidden questions in the sense of an HTML form does, the way that you could do this is by putting the question on a section that the form response flow never show it but on the prefill view all the sections are displayed.
Regarding using Google Apps Script to handle Google Forms a custom URL query string that is not supported, so if that is a deal-breaker, then you should use other options.
If you like so much Google Apps Script you could use it to create a web application as doGet pass the URL query string / parameters to the server side code and also you could grab them from the client-side code by using the HTML Service.

How to export data with Grid.mvc in ASP.NET MVC

I have data in Grid.MVC and now I want export data after filtered or sorted. I don't know how to do it.
Please help me.
Thank all.
I need to export the data in Grid.MVC to Excel. I used the solution in this link:
http://www.adambielecki.com/2013/05/exporting-data-to-excel-and-csv-in.html
It working but i have a problem, i want export data after filted or sorted.
So heres the help I can give you... I had to do this a few years ago with the same technology. Think of the Grid.MVC filtering as "client side". On the server's point of view, the bucket of objects filling the table has not changed when you do filtering, so what I had to do was hook into the filterboxes on the top of the grid by their css names and use a post back of filter objects to the viewbag which were then used in a linq query to filter the objects to the set I desired, from there I was able to export. This was super hard, and I cant access any of my old code b/c it was for a different company.
I would suggest not puttin the effort in, see if your users are okay with "post filtering" since excel is pretty much made to filter / sort data anyways.
Sorry I could not be more help but I hope this gets you started. good luck.

Using an EntryElement with AutoComplete features and Google Places API

Im wondering if you can help me with a problem:
Problem: Im trying to create a dialog with an EntryElement that allows a user to enter an address. As the user enters the address I would like to call the Google Places API to bring back a list of results to ensure the address is valid. The results should be displayed as a list of StyledStringElements which the user can select.
Does anyone have any advise on how to best achieve this?
Thanks and regards. Adam!

Labview to google spreadsheet information transfer

I have been using LabVIEW to collect measurement data, and I would like to know if it is possible for LabVIEW to communicate the results to a Google Spreadsheet. If so, where could I find resources to learn how to make LabVIEW transmit information to the Google Spreadsheet ?
Thanks!
EDIT AND FOLLOW-UP- I used Jonathan's suggestion below and experimented with the LabVIEW http Post.vi. It's very simple, all you need to do is enter the URL of the Google form (replacing the final "viewform" with "formResponse") and a string with the data you want to enter (with rough syntax = ). A big thanks for that answer, it was really helpful !
However, when I try to use this method for a Google form with more than one page, the data isn't read properly... The form is still sent but every field not present on the first page of the form remains blank on the Spreadsheet. I feel that this is somehow linked to the fact that in the Google form, the URL of all the pages after page 1 are the URL of page 1 with the final "viewform" replaced with "formResponse". Is this what is causing the error or is it something else altogether, and how can I fix it ?
I can think of two ways to do this:
You can create a form in google spreadsheets. The form appears as an html document with standard tags. From here, I would use labview's http functionality to submit data to that form using a POST request. This would be the easiest way to get data in there.
Using the Google Apps API, you can manipulate google spreadsheets and dump data in there directly. This is going to be more complicated in terms of development time, but more configurable in the long run. https://developers.google.com/google-apps/spreadsheets/#what_can_this_api_do There are .net and java code examples throughout the documentation, so it would take some work to port this to LabVIEW, but it could be done.
