A quick demonstration on how to control access to files in real-time. As described in the Microsoft documentation , the control access to a file can be added or removed by obtaining the FileSecurity object from that file, then modified, and then applied back to the file. In this example I choose to change the file access properties of a simple icon file "icon.ico": So that before modifying the properties it can be opened straightforwardly as follows: To demonstrate how we can alter the access properties in real-time, create a C# console application in Visual Studio and add the following code. Note the use of WindowsIdentity.GetCurrent() api used to obtain the necessary username/domain details of the current Windows user: [code language="csharp"] using System; using System.IO; using System.Security.AccessControl; using System.Security.Principal; namespace FileControlAccess { class Program { static void Main(string[] args) { ...

1. Load an image and display it [code language="cpp"] //Loads image and displays #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <iostream> int main() { cv::Mat image = cv::imread("spots2.jpg", CV_LOAD_IMAGE_COLOR); if( false == image.data ) { std::cout << "Could not open or find the image" << std::endl ; return -1; } cv::namedWindow( "Display window", cv::WINDOW_AUTOSIZE ); cv::imshow( "Display window", image ); cv::waitKey(0); return 0; } [/code] 2.

Some instructions on how to automatically increment the build number of your Visual Studio project. What was important to me was to automatically increment the build and version number of my executable files using Visual Studio. Some important StackOverflow links helped me to achieve this: https://stackoverflow.com/questions/356543/can-i-automatically-increment-the-file-build-version-when-using-visual-studio https://stackoverflow.com/questions/826777/how-to-have-an-auto-incrementing-version-number-visual-studio To demonstrate the instructions contained in the StackOverflow links, first create a new Visual Studio project. For simplicity, choose a .NET console application: Notice that a file called AssemblyInfo.cs is automatically created: Modify the AssemblyInfo.cs file, so that the AssemblyVersion attribute ends with an asterisk. Also comment out or remove the second of these lines, AssemblyFileVersion, so that we just have the following: AssemblyInfo.cs ...
