I would like to set programatically a background image for the windows logon screen.
How can I do that ?
Prefered language is C# but I can read other languages and adapt :)
Best regards

In the program, you must make creating of one directory and copy JPG file to this directory.

In MacOS, I will modify my screenshot key to use monosnap and then after no modifications or minor ones, I will then use a shortcut key to place it in my clipboard. I am trying to make the same workflow in the windows version.
Here is what I see:
I do not see a setting to "Copy image to clipboard":
If there another way to achieve my goal, please share. Oh btw, I would rather not require the option to upload my images to an external service. Thank you!
Pretty much the same:
1. Focus your Monosnap Editor
2. Press Ctrl+C
Now you have your edited image in clipboard.
I am making a batch file to password protect a hidden folder.
How can I make it so the user cant view the preview window at the side, since the preview window allows them to see the password that is set in the .bat file.
To make the code of your batch file both hidden and un-editable, the best option is to convert it to an exe. I would recommend you use this bat-to-exe converter.
Also FYI, making a folder hidden is a rather ineffective protection step that only works against layman tech users. Perhaps encrypting the folder may be a better solution for you.
how to embed vbs file to image and run the vbs file when an image is clicked or open by the users? Please provide me with a good solution
Running arbitrary code in the background when a user opens an image file would be a severe vulnerability. So no, there is no regular way to achieve what you want.
I have both InDesign CS2 and CS3 installed. Both use files with .indd extension. How does Windows know which icon to use? It uses correct icons i.e. CS2 files have cs2 icon and CS3 files have CS3 icon.
How does Windows know how to do this?
And how can I extract or use this version-detection system in my programs?
Edit:
Thank you for your shell-extension-icon-handler answers. Something new to me. But is there any way I could connect to IconHandler that InDesign provides and use it to detect version of the InDesign file?
You need to write an Icon Handler shell extension. See the MSDN documentation for IExtractIcon. The basic mechanism is that you create a shell extension and register the icon handler for the file type you want (look in HKEY_CLASSES_ROOT/.indd) and then the shell loads your handler, passes the file information and requests an icon in return. There's also the IExtractImage method if you want to provide a thumbnail bitmap rather than just an icon.
Note that you need to be especially careful writing shell extension handlers as any memory leaks or crashes can nuke the explorer and any other applications that display a file open/save dialog.
For some files it's HKEY_CLASSES_ROOT\<file extension here>\DefaultIcon registry entry, but most files map to a more friendly name, e.g. .pdf\(Default) -> AcroExch.Document (if Adobe Reader is installed).
In that case you have to go along the registry to AcroExch.Document and see that either
DefaultIcon is right there or
AcroExch.Document\CLSID\(Default) is some GUID. Then, follow HKEY_CLASSES_ROOT\CLSID\<insert that guid here> and you'll notice that this key contains DefaultIcon
... and DefaultIcon is where the icon is loaded from.
Hope that was clear enough ;). I don't know about your special case but there should be a distinction in the registry.
It almost certainly installs a shell icon extension handler. Writing your own and knowing how to detect the version in a file format that isn't documented well or at all is quite tricky.
I'm creating a small ruby script to resize images and save them in a specified directory. I'd like the application to be as transparent as possible.
Is it possible to allow file dropping onto my Ruby script in all platforms? For instance, the user drags a file onto the script, which then takes the file path as an argument and resizes the image accordingly -- No GUI, no console, etc..
The behavior of drag & drop is dependent on the OS (and in case of Linux of the Window Manager), so no.
In Windows, you get the behavior you want for free. Just put a .rb file on the Desktop, and the files dragged onto it will be arguments to your script.
Another easy way for integrating with Windows is to write to registry entry HKLM\Software\Classes*.jpg\myhandler\command with the command you want to appear in the context menu of Windows Explorer (right click on a jpg file will popup a menu which will have your script in the menu).
I don't use drag & drop at all in Linux, so I wouldn't know how to do that there. I would expect it to have more security issues (permissions must be right, ...) but you could get there by creating a .desktop file, see http://standards.freedesktop.org/desktop-entry-spec/latest/ for the complete standard, or read some examples from ~/Desktop/*.desktop .
Platform dependend, so here for windowsusers and reference only.
Save the following to a .reg file and load it by doublecliking it, tested on Windows Vista and 7
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\rbfile\ShellEx\DropHandler]
#="{86C86720-42A0-1069-A2E8-08002B30309D}"
[HKEY_CLASSES_ROOT\rbwfile\ShellEx\DropHandler]
#="{86C86720-42A0-1069-A2E8-08002B30309D}"
[HKEY_CLASSES_ROOT\RubyFile\ShellEx\DropHandler]
#="{86C86720-42A0-1069-A2E8-08002B30309D}"
[HKEY_CLASSES_ROOT\RubyWFile\ShellEx\DropHandler]
#="{86C86720-42A0-1069-A2E8-08002B30309D}"
Such behavior would surely be platform specific, as drag-and-drop is implemented by the OS in this case, not by ruby.
So answering your question: no, it is not possible.
You can use platypus on os x to create a wrapper around your script.
