Is there a way to call/load an ahk script from https. Like this one. I'd like to keep this file for public editing on github and it would be called from multiple users without the need to download it first..
How about downloading it:
UrlDownloadToFile, https://gist.github.com/gimoya/5821469/raw/034b2766bbcbe70e2a8e93b72d1ec8723351a8f8/Veg%C3%96K-Abk%C3%BCrzungen, hotstrings.ahk
if(ErrorLevel || !FileExist("hotstrings.ahk") ) {
msgbox, Download failed!
ExitApp
}
Run, hotstrings.ahk
You may want to add some check routines for the downloaded file to make sure, that it's syntactically correct and most of all not harmful. That is, you can't trust anything coming from the internet. A more secure way to apporach this would be to retrieve your hotstrings as XML or JSON and build them dynamically on your own; blindly executing downloaded code is very risky, especially when multiple users are able to edit it arbitrarily.

I need to upload a file to OneDrive, via the command line. This will be done through a batch file which is distributed to end users.
From searching on Stack Overflow, I find questions like this one which say that you need to register an app and create an app password, using Azure. I don't have the necessary permissions to do this in the organization where I work, nor can I do anything that requires an admin account. So I can't any install software - I have to use what comes with Windows 10. I can't use VBA either as that's blocked.
I've managed to download files from OneDrive without anything like that, using the process described here:
Open the URL in either of the browser.
Open Developer options using Ctrl+Shift+I.
Go to Network tab.
Now click on download. Saving file isn’t required. We only need the network activity while browser requests the file from the server.
A new entry will appear which would look like “download.aspx?…”.
Right click on that and Copy → Copy as cURL.
Paste the copied content directly in the terminal and append ‘--output file.extension’ to save the content in file.extension since
terminal isn’t capable of showing binary data.
Example:
curl https://xyz.sharepoint.com/personal/someting/_layouts/15/download.aspx?UniqueId=cefb6082%2D696e%2D4f23%2D8c7a%2
…. some long text ….

cucg=1’ --compressed --output file.extension
I tried to do something similar after clicking 'upload' on the browser, but didn't find anything useful when trying to filter the requests.
I found these two questions but there is no keyboard shortcut to upload, AFAICT. Also the end user will be uploading a file to a folder I've shared with them from my OneDrive. Opening Chrome or Edge as a minimised window is fine, but I can't just shove a window in their face which automatically clicks on things - they won't like that.
It's just occurred to me that I might be able to use an office application to Save As the file to the necessary onedrive folder, where the keyboard shortcuts are pretty stable, but have no idea how to achieve that via the command line.
The best and more secure way to accomplish this goal I think is going to be with the Rest API for OneDrive.

You still need a Azure AD App Registration (which your admin should be able to configure for you), to provide API access to services in Azure. Coding with the API is going to be far easier and less complicated, not to mention more versatile.
Interesting.
I wanted to add logic to catch the upload of non-images. In the PHP example in the docs, they had this:
// Verify extension
if (!in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("gif", "jpg", "png"))) {
header("HTTP/1.1 400 Invalid extension.");
return;
}
So I added something like that to my server's backside server-side JavaScript.
But it turned out not to be necessary. The image upload dialogs (either browse or drag-and-drop) somehow don't let you select anything but images.
If that's so, why does the example add that to the handler?
There are a couple of reasons but I'll stick to the main 2:
You may not want to accept all image types, perhaps you don't want users to upload .gif files because it will be ugly to see gif images in content, or perhaps your server doesn't support this type of image.
Using terminal commands like curl or GUI applications like Postman, you can skip the normal browser upload workflow and upload whatever you like to the server. Highly dangerous as users could upload anything if you don't perform some sort of validation, they could upload a .php file for example and cause all sorts of havoc.
I have been given a task that involves downloading a single file every day from a website. Let's call it "https://test.example.com". I have credentials that allow me to login to the site, where a Flash interface then presents the files that are available for download. After the file is downloaded, it is then processed in a variety of ways. I have already put together the Powershell that handles all that, I am just having a hard time with automating the actual download of the file.
I used the Flash interface to download a few files while watching the network activity, and found that it is actually pulling the file from this URL:
https://test.example.com/link/EBDB7F67EF3B28XX99NCAD9920160423/file.zip
Therefore, I was able to put this together in order to automatically get the file via my PS script:
$url = 'https://test.example.com/link/EBDB7F67EF3B28XX99NCAD9920160423/file.zip'
$output = "C:\Downloads\file.zip"
Invoke-WebRequest -Uri $url -OutFile $output
However, the long string of numbers in the URL changes every day. The only discernible pattern I can find is that the last eight digits are always the date on which that particular file is posted.
Is there a good way to approach this? I've been experimenting with wildcards and patterns, as well as checking the HTML for elements that I can filter, but I am having a hard time finding the correct solution.
This is very hard to automate. You can't drive Flash from the script unless it is specifically designed for that. As I see it now your only options are:
Contact site devs if possible, maybe they can give you a details on function that generates link. This gives me an idea - perhaps you can reverse engineer Flash code to find that function details yourself. Use flash decompiler for this.
Simulate the user browsing the flash site. This can be done in one of the following ways:
Autohotkey - you can record mouse clicking relative to the browser window and execute the script again. Unless flash interface is too dynamic and unpredictive it will work.
Sikuli - another automation language which relies on picture segment recognition.
All above 2.* methods produce fragile automation code as they depend on browser settings (zoom, theme) and even OS settings. For this reason you need to dedicate one machine for that in all probability (virtual machine ofc). Decompiling flash code and re-implementing the url generting code in powershell will make it a reliable 100%.
As somebody said in comments this is not a powershell queestion but browser automation question.
I am writing a script that polls an FTP site for files and downloads them locally as and when available. The files are deposited to the FTP site randomly by various source parties. I need a way to be able to detect if the file on the FTP site has been transferred over completely by the source party, before downloading them. Any thoughts on how to go about this?
If you have control over the client, a much safer, cleaner and efficient way is to have the client do the following:
Upload the file to ..../partial/somefile
Rename ..../partial/somefile to ..../complete/somefile
This causes the file to appear in the latter directory all at once, so all you have to do is scan that directory. You could even ask the OS to be notified of additions to that directory if you wanted a non-polling solution.
If you cannot manipulate the FTP server itself the only way of checking that comes to my mind is polling the filesize and if the filesize doesn't change for a longer time you can be quite sure the upload has finished. But nobody can guarantee. Ideally you can adapt the FTP server and make it execute some script after finishing some upload.
Some pseudo-code:
my %filesizes;
my %processed;
sub poll {
foreach (#files_on_ftp) {
if($_->filesize == $filesizes{$_->filename} and not $processed{$_->filename}) {
process($_);
$processed{$_->filename)++;
}
}
}
Like ikegami's solution depends mine of client side:
first is file uploaded
if it is completed, client uploads empty flag-file (like file.name.txt.finished)
When you see finished-file, you know file is ready.
I want to use a dynamic email signature in Thunderbird, that is context aware (depends on date, events in db, etc.)
If I have a PHP that can generate the signature html (i.e. http://www.site.com/email_sign.php)
how do I force Thunderbird to use it?
(the only options I see are using static html (whether inline, of from a local system file).
any ideas?
You can use the Signature Switch add-on and a batch file calling wget to achieve what you want. I wrote a simple executable to replace the bat file; you can read about it (and download it if you want to) from http://www.else.co.nz/portfolio/020-code/dynamic-email-signatures
I doubt you can do this simply. Thunderbird does allow scripting via the creation of plugins but I wouldn't personally know how do do it or how easy it might be.
Best answer I can think of would be to set a scheduled task / cron job to download the php to a local file then follow the instructions in the knowledge base, namely:
You can use Thunderbird to create signature files, or you can use your operating system tools to create them—for example, a plain text editor.
Thunderbird does not provide any
special place to store signature
files. You could create a Signatures
directory in your profile to store
them, making them easy to back up
along with the rest of your profile.
Or you could store them somewhere
else.
To use a signature file, specify it in
Account Settings as the signature for
an identity. Check the box "Attach the
signature from a file instead" and
specify the signature file.
This will work unless Thunderbird caches the HTML internally, however I see no indication in the FAQ that this is the case.
For years I updated the signature for my email client manually – until I got fed up… That’s why I wrote a PHP script to create a randomized signature block automatically from an RSS feed! Check it out: https://github.com/birdy1976/signature :-D
