I'm using VirtualBox's XPCOM to interact with the VirtualBox information. So far everything works well. Now I'd like to interact with VirtualBox for different users. Is there any way to do this? It seems that the XPCOM only starts the VBoxSVC process for the current user. Is there any way to have it start it as a different user? I've looked into using vboxwebsrv as well, but the sdk says that it will only get the VirtualBox information as the user it is started as.
Also, assume I can run the XPCOM client program as root, so it has access to everything. Is there anything I can do to make this work?

I would like to create a custom 2FA on Windows XP (and above) for personal computers.
I know Windows XP is discontinued, but I'm using an old program relying on Windows XP, so for now I'm stuck on it.
I can write C/C++ code, but I don't know C#. So I'm trying to figure out a way to suspend userinit to show my app, then my app will either let userinit do its thing, or logout the user.
I've tried changing userinit in the registry to put my app which would load userinit itself, but it's easily hackable: My app can be closed, leaving the computer in a lockdown state, or taskmgr can be used to launch userinit or explorer.
If there are better way, I'm opened to suggestions, but I'd like to avoid ready made solutions (Rohos Logon Key works but can sometimes be worked around)
As far as I know you can do it only on C++ to implement GINA (for Windows XP). For Vista (and above) you need to implement Credential Provider. It can be implemented in both C++ and C#.
I'm entering the world of Shiny Rstudio now. So this is a beginner question
One question I came up with is: how do I search for the Shiny Apps available/created? Are all created Apps available? Is there any way that, once I create my app, I prevent it from being viewed? Or during the creation I "block it"?
From so much searching I found this link via Rstudio's website: http://www.showmeshiny.com/
Would this be the search platform for all apps made?
But in the case of http://www.showmeshiny.com/ it seems that it is necessary to send it via "Submit App".
I am not sure if I understand your questions correctly but I might be able to give you some insights.
Are all created Apps available?
No, some shiny Apps are hosted on private servers or/and are embedded in password-protected websites or Wordpress-pages for example. If you dont have those access rights, then you cannot see those Apps.
How do I search for the Shiny Apps available/created?
There is no way of doing that, except on pages like Showmeshiny, the RStudio Shiny Gallery, this gallery of recent Shiny-Apps or pther similar pages. Those Apps are publicly available and you can submit your own App if you like sharing it. Shinyapps.io is a nice and easy way of deploying your App on a server with a few clicks. But you need at least the standard license to include authentication, otherwise they would be free and open for everyone.
Is there any way that, once I create my app, I prevent it from being
viewed?
I am not quite sure, what you mean. If it should be blocked from being viewed at all, I dont see the reason of building a ShinyApp. If you just want to access it yourself, then there are ways of doing so. Either password-protect it where only you know the password or host it on a local server that only you can access.
Or during the creation I "block it"?
If you create it on your computer and run it, it will run on your computer and only be accessible to yourself, except you explicitly configure it otherwise. So there is no need of "blocking it".
I ask here because I've asked on the Unity3D forums (in July) and nobody has responded, and I still have the same issue.
I have an AWS EC2 instance and I am using it to develop with Unity3D.
The problem is that while the keyboard and mouse work perfectly fine in the editor, the mouse stops responding when in "play" mode.
I access my EC2 instance via Windows Remote Desktop, I have an Administrators account and I have all drivers up to date.
Any ideas?
Update
I am doing research, so cross-platform compatibility is not a concern. I'm using Windows because the tools I require, require Windows. Changing OS is not an option.
I've tried starting the editor with admin. I've also tried launching the remote desktop with admin. Nothing fixes it.
Even the standard Unity3D demo applications have this issue, so it is not something that I am doing.
Recently I have been experimenting with Firebreath and developed a plugin in order to showcase my c++ projects on my portfolio website. I would like to make it easy for users to look at the projects without downloading files if they are new on my website.
The only issue I have at this point is that when users visit my page, they will receive a message indicating the plugin is missing. I would like to have an option for the users to automatically install my plugin without having to manually download and run it.
The plugin is mainly targetted at Windows users, since the applications are as well. I intend to support Google Chrome, Firefox, Internet Explorer. Currently I am using a MSI installer to install the plugin.
I have found a question similar to this, but I still needed to save the MSI installer and run it.
My question is: What would be the best way to implement this?
There isn't any way to "automatically" do what you want to do. The closest that I have heard of would be to use a java applet that would download and install the plugin for them. This can be pretty reliable on Mac but far less reliable on windows (for a number of reasons, among which the fact that many windows users don't have java installed and that Chrome blocks java applets by default without intervention by the user).
Other options include:
Creating a CAB file installer (only works on IE)
Creating a XPI firefox extension that packages the plugin (requires restarting the browser, only works on firefox)
Creating a CRX chrome extension that packages the plugin (only works on Chrome)
Microsoft ClickOnce used to work pretty well for one click installs of MSI files from a web page, but recently I think it doesn't work on many (if any) browsers; haven't seen it used in awhile, anyway.
There is no "automatic" way to install plugins; that would be considered a severe security issue. This is probably the #1 reason that plugins are as uncommon as they are.
do what adobe does,
create a tiny activeX application downloader, sign the activeX from with cheap SSL
when a user, enters your site, he will automatically be downloading this tiny ActiveX, after installation complete, inside the tiny ActiveX, have some type of batch script to download the EXE from remote server and silently install it.
adobe does this, on every reboot in boot.ini or startups
very easy
I am having a desktop application which having a UI interface made in Qt linked with a library which is doing all the calculation stuff. Values from UI is taken and pass to the API's in the DLL to get the output which is shown on Screen.
Now i want to do the same thing by transferring my application UI to a web page so that people can access the tool from anywhere without any installation process.
I want to retain my c++ DLL code so i don't have to do a lot of work. I am thinking of just converting this DLL to a C++ server by any communication Process(Sockets). I want to host this application on my company's website. (We have to make the website also so we are open to any set of tools).
I want to know what will be the best set of tools to do this stuff. Also there will be lot of data exchange between the webpage and server so the wholething should be optimized also. I goggled a bit and find stuff like silverlight and ASP.NET, But i am still not very clear which option will be more suitable.
I am a c++ programmer with no web application development experience. I am open to learn any new technology.
Thanks
Why not use Qt on the web directly? There are several projects like this one: http://qtwui.sourceforge.net/
There is a netscape plugin that will host a QT application and an ActiveX control wrapper on the QT website. You could use one of those to wrap your application. Note that this approach would require the user (or their administrator) to download and install the plugin.
An alternative approach might be to run your application through a remote desktop such as XVNC, NX or an RDP based layer. IIRC browser based remote desktop clients are available for most such protocols.
A few options:
pick a messaging/queue implementation (like http://www.zeromq.org/) and provide a service
implement a Windows Web Service if you want to be more enterprise friendly: http://msdn.microsoft.com/en-us/magazine/ee335693.aspx
I would not expose the implementation on the internet. Enough to have a simple buffer overflow and the machine can be taken over quickly. Adding a layer between the app and the web provides an easy way to validate input, access, stats ...
You should be able to use your DLL from an wt or cppcms application. Then you do not have to learn something new and can just use C++.
The way I'm currently doing this is with Boost.Python + django
