I'm just trying to get a quick way to play and pause Windows Media Player remotely. After reading several questions here on SO, I realized that most people were talking about C#, Java, COM, ActiveX... which seem a bit overkill for my project. Is there any simple interface to mess with WMP? My preferred approach would be some Python module where I can just script something up really fast and have it deployed in five minutes. Nothing too fancy.
You need this:

Here's an answer, 3 years later, for 64-bit systems:
import win32api #needs the pywin32 module
win32api.keybd_event(0xb3, 34) #send the MEDIA_PLAY_PAUSE event

I was tasked to set up an open-source icap-server to scan files that are uploaded in one of our web applications.
The files base64-encoded withing the upload method and this seems to lead to the fortigate not being able to scan it properly.
Now I managed to set up an icap-server using "c-icap" and tested it with "clamav". So far it seems to work, at least EICAR files are detected.
Now the problem is, that my boss is basically a "Windows-only" person who says that any open-source AV can´t be trusted enough.
He wants me to try to have the requests/uploads sent to the c-icap server, but scanned with Windows Defender. ß Is there any - useful - way to accomplish this? Also, since I am super new to ICAP - are there any restrictions regarding which icap-server can be used?Like, is there any way to force requests to be handled with a metadefender-icap only, and not any other icap server?
Sorry if these questions are a bit unspecific and basic, but just started with ICAP yesterday!
Thank you!
Check out this link: https://techcommunity.microsoft.com/t5/windows-it-pro-blog/metadefender-icap-with-windows-defender-antivirus-world-class/ba-p/800234 to see what Microsoft offers regarding Defender+ICAP.
I have used commercial ICAP solutions in the past (like Bluecoat) that allow plugging in multiple commercial virus engines (Kaspersky, Sophos, ...).
These are appliances, and you don't need to tell your boss their internals are probably some sort of Linux ;-)
You can probably also set up a commercial antivirus solution on your Linux system and use that.
Looking at this link: https://learn.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-atp/microsoft-defender-atp-linux it may even be possible to run Microsoft's Defender on Linux. I haven't tried it myself though.
Unlike your boss, Microsoft realizes software shouldn't be made to just run on Windows anymore (even MS-SQL Server now runs on Linux).
Probably there are a lot of similar questions around, but since I know only few solutions to this which I am not sure will work for us, I am looking for something else, maybe new technologies...
What we have is this USB device which is not so fancy (of course, it requires a driver to be loaded), and it has couple of C++ dlls to help getting certain output from it. On top, we made a C# desktop application which makes use of the device in a more attractive way (plenty of interop inside).
So far so good, but to have the application lifted up to the web in order to gain more flexibility... What options are there?
Known solutions are:
1) ActiveX - kinda old technology and not cross-browser;
2) .Net 'applet' - not so common (is this even a solution?)
3) Java applet - well known, but JVM needed (since we went for C++ C#
maybe is out of scope);
4) Web service on the usb device itself - our device is very
light, we cannot have it there.
Are there other ways? Is Silverlight 4, 5 (maybe "out of browser") a feasable solution? What about these new technologies nowadays? Html 5 or something?
EDIT1: In particular I am interested in Silverlight. Is there a way using Silverlight?
EDIT2: I found this question: Can Silverlight access a .Net library that accesses a USB port? . What shall I understand from that? Is really Silverlight not a feasable solution for my scenario?
EDIT 3: VERY IMPORTANT!
These devices need to be used on customer side! People browsing must use them locally on their PCs!
Thanks in advance.
to have the application lifted up to the web [...]
Simple solution: Let the webserver (http server) run on the PC connected to the USB device, and use one of the webserver's interfaces like CGI to talk to your USB device. This way you need to code only a USB-to-CGI wrapper program, which can be C++ or C#.
Another way is to write a browser plugin.
The issue that you're going to face is that content in a browser is often run in a sandbox, in such a way that the web app does not have access to the computer. There are good reasons for this - security, primarily. One way to have some code running in the context of the computer is to have a browser plugin that can access the computer's hardware resources, but that can interact with browser content. Unfortunately, you may end up writing a different plugin for different browsers.
There do exist frameworks out there that make writing browser plugins more manageable. A simple search should turn up some of those candidates.
You can use Silverlight 5, it can give you access to your file system and USB storage device. If you want to get control for other USB device (printer, scanner, etc), you should give a device type. I know, Silverlight 5 works fine with a file system and web-cams...)
What happened to the home page of FluxJpeg (or FJCore)? Many pages point to
http://code.google.com/p/fjcore/
but that page has no downloads available as of today (June 28, 2011).
Q1) Where can I download it from?
Q2) Is there anything better? I need an open-source class that I can use from Silverlight 4 to decode a JPEG, reduce its size (preferably using some interpolation algorithm) and encode it back to JPEG, to upload the file to a server.
Thanks a lot.
I think you're supposed to use Subversion to check out the source, and then build it yourself: http://code.google.com/p/fjcore/source/checkout.
Alternatively, you can use LibJpeg.NET: http://bitmiracle.com/libjpeg/. It's a straightforward port of the unofficially canonical libjpeg. Only downside is that it's more complex and a bit harder to hack on.
Q2.
Have a look at imagemagick Very stable, tons of functionality and the likelihood that it'll disappear is close to 0
I want to make project for my final year in college.
So someone suggested me to make Remote Desktop in C.
Now I know basic socket functions for windows in C i.e. I know how to make
echo server in C.
But I don't know what to do next. I searched on internet but couldn't find
something informative.
Could someone suggest me how to approach from this point..any tutorial...or any source ?
I think this is do-able. For a college project, you don't need to have something as complex and as full-featured as VNC. Even demonstrating simple keyboard and mouse control and screen feedback would be enough, in my opinion, and that's well within reach.
If you're doing everything from scratch and using Win32, you can get the remote screen using the regular "printscreen" example all around the internet.
http://www.codeproject.com/KB/cpp/Screen_Capture__Win32_.aspx has it, for one. You can then compress the image with a third-party library, or just send it raw; this wouldn't be very efficient but it would still be a viable demonstration.
Apart from capturing the screen data remotely and showing it in the local window, you'll need to listen for local window messages for mouse and keyboard events, send them to the remote host, and then play them back. http://msdn.microsoft.com/en-us/library/ms646310%28VS.85%29.aspx will probably do that for you.
Check tightvnc TightVNC is a free remote control software package. The source code is also available.
For sending the image of the screen I would probably use rtp. The JRTPLIB is really handy for that.
And yes, as KevinDTimm says, an echo server is the very easiest part.
KevinDTimm may well be right, writing an RDP client would a fairly significant undertaking. To give you some idea, the current spec, available at the top of this page, is 419 pages long and includes references to several additional documents for specific aspects of RDP like Audio Redirection and Clipboards.
If it's possible, I'm interested in being able to embed a PostgreSQL database, similar to sqllite. I've read that it's not possible. I'm no database expert though, so I want to hear from you.
Essentially I want PostgreSQL without all the configuration and installation. If it's possible, tell me how.
Run postgresql in a background process.
Start a separate thread in your application that would start a postgresql server in local mode either by binding it to localhost with some random free port or by using sockets (does windows support sockets?). That should be fairly easy, something like:
system("C:\Program Files\MyApplication\pgsql\postgres.exe -D C:\Documents and Settings\User\Local Settings\MyApplication\database -h 127.0.0.1 -p 12345");
and then just connect to 127.0.0.1:12345.
When your application quits, you can always send a SIGTERM to your thread and then wait a few seconds for postgresql to quit (ie join the thread).
PS: You can also use pg_ctl to control your "embedded" database, even without threads, just do a "pg_ctl start" (with appropriate options) when starting the application and "pg_ctl stop" when quitting it.
You cannot embed it, nor should you try.
For embedding you should use sqlite as you mentioned or firebird rdbms.
Unless you do a major rewrite of code, it is not possible to run Postgres "embedded". Either run it as a separate process or use something else. SQLite is an excellent choice. But there are others. MySQL has an embedded version. See it at http://mysql.com/oem/. Also several java choices, and Mac has Core Data you can write too. Hell, you can even use FoxPro. What OS you on and what services you need from the database?
You can't embed it as a in process type thing like sqlite etc, but you can easily embed it into your application setup using Inno setup at http://www.innosetup.org. Search their mailing list archive and you will find someone did most of the work for you and all you have to to is grab the zipped distro and you can easily have postgresql installed when the user installs your app. You can then use the pg_hba.conf file to restrict the server to local host only. Not a true embedded DB, but it would work.
PostgreSQL is intended to run as a stand-alone server; it's probably possible to embed it if you hack at it hard and long enough, but it would be much easier to just run it as intended in a separate process.
HSQLDB (http://hsqldb.org/) is another db which is easily embedded. Requires Java, but is an excellent and often-used choice for Java applications.
Anyone tried on Mac OS X:
http://pagesperso-orange.fr/bruno.gaufier/xhtml/prod_postgresql.xhtml
http://www.macosxguru.net/article.php?story=20041119135924825
(Of course sqlite would be my embedded db of choice as well)
Well, I know this is a very very very old post, but if anyone has nowadays this question, I would refer to:
You can use containers running Postgres. Here's a post that could be helpful, doing something along this line using R:

Take a look at duckdb https://duckdb.org/docs/installation/ It is relatively new and still needs to mature. But it works pretty much like an embedded database ("In-process, serverless"), with bindings for several languages (Python, R, Java, ...)
