Demonstrates using .NET Remoting to broadcast to client subscribers. There are three parts: 1) Server.cs - for console app responsible for broadcasting messages (date/time stamp currently) 2) Client.cs - for console app that registers with server to subscribe to broadcasts 3) Agent.cs - class library that facilitates/eposes the interfaces for our client/server communication To use, create the three project types defined above and include the appropriate code found in this snippet. In both the Server and Client projects, add references to the Agent.DLL project. Then, modify the IP address in the ClientClass's creation of the AbstractServer remoteObject to a string …

An example showing how to use the wx.media.MediaCtrl() widget to play MIDI, MP3, WAV, AU, AVI and MPG audio and video files. I have only tested it with Windows. If you are very ambitious, you could use a random graphics display with the sound, or tie the slider position to a slide presentation.

This short Python code gets the local time from the PC as a formatted string using time.strftime('%H:%M:%S'). The time string is displayed in a label using a larger font. A recursive function checks the time five times per second, and updates the time string, if it has changed. Five times per second may sound like overkill, but keeps the display from acting spasmodic.

Hi. I want to detect a face and draw line exactly around the face to crop it. I searched a lot and used the EmguCV face detector. but now my code just draw a "rectangle" around the face and if I crop it, I will have a rectangle with a face inside it and it's not useful for me. this is the core of my simple code: CascadeClassifier _cascadeClassifier = new CascadeClassifier(Application.StartupPath + "/haarcascade_frontalface_alt_tree.xml"); using (var firstImage = Image.FromStream(saveImageStream)) { var bgrImage = new Image(new Bitmap(firstImage)); Image grayFrame = bgrImage.Convert(); var faces = _cascadeClassifier.DetectMultiScale(grayFrame, 1.01, 1, Size.Empty); foreach (var face …

Let's say you want to send a short private message to your friend, but don't want grandma to snoop around and find it. One way is to use the Python Image Library (PIL) and hide the message in a picture file's pixels. Just looking at the picture you will barely detect any difference between the before and after picture. All your friend needs is the decode_image portion of this simple code to get the message back.

I have a table that contains some cubes with servers and active status (see attached image): note: CUBE1 is repeated intentionally. The idea is the same cube is getting synced from the same server 1 as a data source (process_server) onto different target servers (query_server; say server2 is in region A and server 3 is in region B). The way the environment is set up is both servers have to be active/active status (meaning TRUE) except for some additional test cases, i am setting to false sometimes one or the other. I have the following script now calling the cube …

Hello! I am interested in the issue of protecting the code from hacking. Do you protect your code from decompiling and hacking? Why did the question arise? I worked in a team that developed games for Android. They all used obfuscators! So almost no one could hack their application. Now I am interested in the topic of code protection. I looked at the existing topics, they are slightly outdated (8-10 years ago were relevant). Use / not use obfuscator? Which to choose?

I am doing a team project with some people that prefer Linux and some people prefer Windows. We are also not allowed to share code for security reasons. One thing the Windows people love to whine about is a way to hold the window open. So the way they usually solve the problem is with: #include <conio.h> getch(); This creates a problem for the Linux users since we do not have that library. I have been looking for ways to solve this problem and I really like this idea. https://www.dreamincode.net/forums/topic/30581-holding-the-execution-window-open/page__st__30__p__575874&#entry575874 #include <stdlib.h> //For system commands //Detect and define which command …
