looking for some help with a rather unique or interesting issue. I am currently in the process of creating a website and would like to implement the following.
I have a download button where the end user can click download - Easy enough.
The complicated part is achieving the following
I would like to provide (automatically) the correct file for the user based on their operating system, so if the user is using windows and clicks the download button the windows file will be downloaded, and the opposite applies for mac.
any help is appreciated.

I am beginner in Operating Systems related stuff. I am working on a project. In this project, I want to know if user is uploading any confidential document on Internet via websites like Gmail ,etc. I don't want to use proxy or networking techniques for this.
If user uploads document to any website, the native FileChooser Dialog opens in any Operating System through which file to be uploaded is selected and opened. I want the path of the file chosen through this native FileChooser Dialog. Once I get the path, I can know through some logic (can't share it), if that file is confidential or not.
File Chooser Dialog
So, I just want to know, how can I get the path of file that user has selected in FileChooser Dialog.
What I have done -
Made Custom Dialog in Java but can't find a way to replace native OS dialog by this custom dialog.
I also found the GNOME module for FileChooserDialog but I have no clue on how to proceed after it.
I have visited all SO questions but they are not specific to my requirement.
I want a code (any language) or script based solution to this. Please help.
Operating System - Any GNOME based Linux Distribution (preferably Ubuntu)
I want to know if it's possible to launch windows applications from a website. If it is possible, how? Sort of like battlelog for battlefield, when a button is pushed it opens an application.
Edit: This is for personal use
Try this:
Make each button be a link to download a company template file for the given application. For example, the "Excel" button would download and the user should be prompted to open it with Excel.
For instance, try clicking one of the links here:
http://www.google.com/#sclient=psy&hl=en&q=template+filetype:xls
Linking to static files on the web server should be sufficient, so long as your server sends the correct MIME-Type or Content-Type.
HOPE it helps!
Take a look at this thread. it should point you in the right direction. In short you can do this in IE using ActiveX objects. But I must warn you that it is a very bad idea
Does anybody know a way I can automate the right click and save as actions for IE, Chrome and Firefox?
I am doing some selenium work using Maven and need to be able to download some files but I am unable to do this as the save as windows cannot (to my knowledge) be automated by Selenium as they are OS dialogs.
I disagree with Bob, Bill and the author of the article that is linked to in the other answer.
Downloads can be automated. The downloaded file can be meaningfully verified. In simplest case you can compare the contents of downloaded file with an existing exemplary file.
(Disclaimer: the next paragraph is about a tool which I am affiliated with).
For example if you use RIATest for automation you can automate the right click, then automate the OS dialog, then wait until the download is finished and verify the content of the downloaded file.
I am thinking about having the following use-case:
User installs application on local machine.
User goes to our website, and are presented with many links (choices).
User clicks on a link.
Application starts, with some information contained within the link passed to the application.
Step 4 is obviously a security minefield. The end goal is that the user makes a choice, and if the application is installed, it starts with some information passed to it (ie command line parameters, or perhaps a temp file somewhere on the user's machine)
Can I/ Should I access the registry from javascript? Are there any ideas about how I might go about this? Do you have an alternative suggestion?
Assuming the applications the user installs are also developed by you.
Register a file extension for use by the specific application - then your web links can be links to a file that is downloaded and auto-run by your app. The file could contain details on the defaults for your app to use.
Sort of like how clicking on a .pdf file opens your pdf reader.
As an alternative to the file-extension solution you may want to know about Custom Application Protocol feature. Link is for Windows but there are nearly same techniques on other systems. I can't say if this approach works in every browser but you may want to try it out.
Accessing the registry from JavaScript inside a browser is nigh on impossible for the security implications. To access the registry from the web, I'd imagine you'd have to use a binary (C++ or others) program that can read the registry, but also has an HTTP module to communicate with your server.
Sounds like you might need the Click Once deployement feature for your app. I think once it's installed over http there should be a pretty easy way to launch an executable.

We're using the Mantis bugtracker (version 1.1.8), which is based on PHP. To ease the workflow of adding bugs we'd like to add an option to paste screenshots from the clipboard directly into the 'new bug form'.
Screenshots make bugreports much more valuable for developers, so I'd like to make adding them as easy as possible. Preferably without using an external application, but right in the browser.
I've looked all over for a way to add this, but no luck. How do other people do this? Am I missing something obvious?
edit: The bugtracker is a private one, in a small company, so I'd be willing to accept the security risks that for example Java applets present.
There isn't really a way to do this short of using ActiveX, applet or Flash-type technology on the client. Even then, there are numerous security roadblocks. A browser has no easy way to convert stuff from the clipboard into a suitable format for upload to a website, and even if it did there would be security concerns. For example, malicious code in a page could copy sensitive information from your clipboard and send it to the page's site without you even knowing it was happening.
Update: There is a standalone screen capture utility which claims to work with Mantis (and a whole bunch of other bug-trackers). This is probably your best option.
There is a drag n drop image attacher Java applet for Atlassian Confluence which has the functionality you need. It only supports Confluence but as the sourcecode is freely available under BSD you should be able to customize it to your needs.
Forgot the link:

I've managed to build my own solution that works quite well. It places a Java file upload applet on the pages where you'd want to attach a screenshot. The applet has two buttons:
'paste screenshot', which pastes an image from the clipboard into the applet
'upload screenshot', which uploads the pasted image to the /tmp dir on the Mantis server and uses a javascript callback to place the autogenerated filename of the uploaded image into a form field.
Once the form is submitted, a new function in Mantis uses the filename in the form field to move the image from /tmp to the final location and processes the image just like other attachments. If the form is never submitted the uploaded file remains in /tmp and will eventually be purged by the server.
It works well, but has one drawback that I cannot avoid: I'm using Java to get access to the client's clipboard, but that requires breaking the JVM sandbox. Apparently, this can be done if you digitally sign the applet, which requires a rather expensive yearly payment (something like $500) to a company like Verisign (currently free options like cacert.org are still limited in their usefulness).
Another way to allow Java applets access to the clipboard is to create a file called .java.policy in your home or profile directory. This file should contain the following (Replace the domain with the domain that hosts your Java applet):
grant codeBase "http://bugs.example.com/-" {
permission java.awt.AWTPermission "accessClipboard";
};
Thankfully the solution is cross-browser compatible since the JVM always checks the same file regardless of the browser used. Since my solution requires having this .java.policy file on each client computer I don't consider it ideal, but workable in a controlled company environment.
I looked in to this also. No real easy way, so instead I allowed them to upload an unlimited number of files and those files would then be "attached" to that bug. It actually turned out to be better because they can upload screenshot, spreadsheets, word docs, etc.
Like yours, this is an internal only site so security is light. I did this in ASP.Net, but the general idea is that when they are looking at a page for a bug they have an upload box. When they upload something I pre-append it with the bug id. So ScreenShot.jpg becomes 233_ScreenShot.jpg.
Also on that page is a grid (GridView) that is bound to all of the filenames in my upload directory that start with that bug id.

For tech-oriented users, there's always to possibility of using Eclipse + Mylyn + Mylyn-Mantis connector.
Then uploading screeshots is very easy:
