I want to know if there is a way to check if a file has been edited. I looked for methods that can make it for me on Google Apps library, but I have found nothing about it. I don't know if I searched wrong.
Basically, I need to take a file, take a measurable data (something like size) of this file and store on a variable. Then, I need to take that measurable data again, store on another variable, and compare if there was a change. I need a boolean return.
Anyone?
You could do the following (pseudo with links to documentation):
Get the file you want to check using the DocList Class.
Get the ID of that File once you have it using File.getID()
Get the last edit timestamp using File.getLastUpdated()
Store this value in a Spreadsheet, or maybe Script or User Properties.
When you want to check to see if the File was updated, simply File.getFileById()
Repeat step 3.
Then compare the two last-edited timestamps with an operator like !=, or do more complex comparisons on the Dates if you want.
Depending on the result of step 7, return true or false.
Google's documentation is great, for all their services. You just need to read it a bit to understand what kind of power you have through scripting. Hopefully my pseudo-method helps in solving your problem!
Look at the file update date: https://developers.google.com/apps-script/reference/drive/file#getLastUpdated() and for storing data look up the storing data section in the apps script help page.
You could also use the GAT General Audit Tool http://goo.gl/hzZ2yf... which reports when files were edited , viewed and much more.

Update: It worked for 5 minutes then stopped working again. Not exactly sure why it's only working part of the time?
This sounds like it's supposed to be simple but I'm only finding information on "getActive" and my function works if I'm using all internal sheets but I tried using openById and nothing happened and openByUrl returns an error. The following is a simplified example of what I'm trying to do:
var store_data_sheet = SpreadsheetApp.openByID('ID here..').getSheetByName('Data');
store_data_sheet.getRange('A1').setValue('testing')
store_data_sheet.insertRows(1);
I'm sure I'm just using the wrong keywords or maybe this isn't even allowed but multiple users will be using their own copy of a specific sheet that runs this function and I'd just like to take certain cell's data and copy it to one external sheet (which is why it also inserts a row so it can push down entries)
Maybe I'm using the wrong "ID"? I assumed the number inside the URL was the ID. If it's something more specific, please let me know.
Like I said, this works flawlessly if I'm referencing an internal sheet. I'd like to be able to do the same exact thing with an external spreadsheet if possible. Thank you!
I found the issue. This function also renames the sheet file so if there is anything in the cell that is used to rename the file, it won't run the storing functions. I either need to run these before the renaming or take out the renaming aspect. ---moving these before the renaming part fixed the problem.
Sorry - I'm a total newbie with InstallShield. I've inherited an InstallShield 2013 project that presents the user with a dialog that let's the user select a SQL Server and based on their selection sets a value in a config file. That's not working, so I opened the project in IS and looked in the Text File Changes under System Configuration and there's nothing there that would do this. So how do I figure out where this is happening (or not happening in my case), and then how do I get it to work? I need to set both data source and initial catalog in a file called server.config.
So how do I determine what the user selected and then save that in this file? It looks like I can set up a Text File Change, but how do I access the values selected by the user? And how can I figure out where the "code" is that is supposed to be doing this?
Thanks,
Ben
I would try to track this from the dialog and controls in question, or by following the value through a verbose log. Since you say it doesn't work today, there will probably be an interruption in the flow I describe below, and since you don't know the full state of the installation project, it may be hard to identify. So search from what you know.
Top down: what gets configured
First, find the dialog that you fill out as a user making the selection. Then figure out the property that the particular control is associated with. Now you've got a thread; pull on it.
Search in the direct editor for references to the property. If the property is named MYCONFIG search for just that: MYCONFIG. You'll probably find some sort of use that looks like [MYCONFIG] instead, which is typically a format string specifying to use the value of MYCONFIG. You may also have to search all the files related to your project, as Custom Action implementations can be code stored outside of your InstallShield project.
The use may be in a ControlEvent, CustomAction, or some other table. If it's in a ControlEvent, it may be used to set another property. Ditto if it's in a CustomAction that sets properties (type 51) which may be easier to understand in the Custom Actions and Sequences view. In that case, also search for the property that gets set.
If you find it in a table like ISSearchReplace* or ISXml*, or IniFile, it's probably part of the Text Files Changes, XML File Changes, or INI File Changes, and that view should make it easier to understand.
Maybe that thread dead-ends somewhere. A property gets set, but never referenced. So try to search from the other end.
Bottom up: what gets written
If there are text file changes, xml file changes, ini file changes, or custom actions that reference the file you need updated, see where they get their information. Try to follow it back. If they're well written, you should be able to identify the property (noting that one called CustomActionData comes from a property matching the name of the custom action it's used in), and then trace that further back using the same ideas as above, but in the other direction.
Where's the problem?
If the threads don't connect, that's probably the problem. It's also possible that a custom action lacks permissions but doesn't reports a failure, or that the file name or path got misconfigured somewhere along the way. Look for small things like that if things look like they should work but don't.
It turns out that I misunderstood the problem and the project was never set up to change that value, so all I had to do was set up a Text File Change and it works perfectly. Thanks #Michael Urman for the thorough response - I really appreciate it!
Good evening,
I am currently developing a way to import machine created data from a csv sheet into a database.
The question I have is, is there a way to react to a change in a csv file with Lua.
The file gets a line in this format:
17162H,"801234500001",9/23/2016 12:33:30 PM,"INV"
Every time a scanner is finishing a scan process, added under the old lines, but there is no direct connection to the database, to trigger the script.
It doesn't matter if the change is detected via different file size, foldersize (of the folder that contains the file) or a change within the file information (like date of last opening), but I can't open and read in it permanently due performance reasons.
Also this is the first time I ask here, so sorry for my clunky way, I'll try to improve myself with that over time.
Take a look at linotify, it has lua bindings for inotify and looks like it should do the trick, using the "modify" event to trigger your script.
I use LibUV based variant in my spylog apllication
Usage:
file_monitor(path_to_file, {eol = '\r?\n'}, function(line)
...
end)
If you need to run this on Windows, you can use winapi library, which supports file watchers. Here is an example of how it's used in one of my projects; you'll need to call winapi.sleep() to allow time for the check to trigger.
this is one heck of a confusing question to ask so here it goes. Firstly, I'm not asking you to write me any code I just need help going in the right direction for what I'm trying to achieve here. Basically the task is this, I want to scan a select area of a web page's source code for changes and if something does change, I want to report it somewhere (like a console or something). However, I do not want just a notification of change, I also want what the change is/was. I've been looking into things like jsoup but I am still struggling to even find out what this is called.
Any pointers would be insanely appreciated. Thanks, Optimistic.
Here are some steps assuming this is from a node.js project:
Get the URL for the specific script file you're looking for a change in.
Using the request() module, fetch that URL.
Break the data up into lines (probably using .split()).
Find the specific line you are looking for either by counting line numbers of by searching for some representative text in that line.
Using some sort of search in that line (perhaps a regex), find the current value of the exact item in that line you are looking for.
Save the current value.
Then, at some future time, repeat this whole process and compare what you find to the previous value.
If this is being done from a browser instead of node.js, then use an Ajax call to retrieve the file. If the file is on another domain from your web page and that domain does not permit cross-origin requests, then you cannot solve this problem in an automated fashion from a browser in your own web page.
Here is how I would do it with Jsoup:
Document doc = Jsoup.connect(url).get();
String scriptCssQuery = "script"; // Tune this CSS query to find THE script you need.
Element script = doc.select(scriptCssQuery).first();
if (script != null) {
String scriptLines = script.html();
// Store the changing line somewhere and compare it to its previous value...
}
I'm looking for a way to recursively generate links to next pages on a website with canonical structure. In essence, I'm trying to generate a link to each next page and then feed that result back in to the process to find the following page ad infinitum. However, I'm having problems automating this as the macro seems to be trying to generate the result for cells that are empty (i.e. the results for an earlier cell hasn't been created/copied yet).
So I'd like to sequentialise the macro to start from A20, generate the result for that cell, copy that result to A21, then begin the macro again for A21, et cetera, without requiring constant human input.
The Google spreadsheet with the error can be seen here in cell C27 and the macro itself can be seen here.
I realise this may be quite a roundabout way to perform this task and am open to any suggestions that may be easier, more intuitive, or faster.
So two suggestions: one is that with stuff that is a continuous scroll, its very easy to find the json of the source, and either grab all the data you want in one go, or by easily picking out the "next page" or pagination...
I personally use importdata() and importxml() more than any other functions, and when in google sheets I also use regexextract() and regexreplace() when needed.
for example the json your looking for is here: http://iconosquare.com/controller_nl.php?action=nlGetMethod&method=mediasTag&value=cricket&max_id=1145408330912313787
if you look at the top row, it tell you what the next min and max is so technically you could just extract that piece to generate your url.
Second option is to just build the query such that it autoincrements the urls. I can give you an example, but I would like to understand a little more about what you really want in the end result...
Are you just looking for the pagination urls, or are you wanting to extract the actual data from them?
