If you want to create an executable file from your ‘C#’ project or file, your code should contain a ‘static Main’ method. This is an entry point to ‘C#’ program. Otherwise, ‘C#’ compiler will throw the below error: error CS5001: Program ‘xyz.exe’ does not contain a static ‘Main’ method suitable for an entry point To […]
.Net supports to use of COM (Component Object Model) functionality within its managed code through its COM Interoperability feature. In this article, we are going to discuss the steps to use COM components within the ‘C#’ code. Step 1. The first step is to add the COM component as a reference to the C# project. […]
In our previous article, we have used “getrecord” function. We will start this article with this function. We have to implement “getrecord” to fetch a record from the “employee.dat” file. It will check the “employee.dat” file for an employee record based on the given employee number. If it finds the employee record it will return […]
In this article we will look into few more things about the classes. Outer Classes, Inner Classes and Wrapper Classes ‘C#’ classes allows to define classes (inner classes) within the classes. Inner classes are only accessible through its outer classes or wrapper classes. To create an instance of an Inner class, we have to create […]
We are almost done with our module. Just we have to implement the functionality when the module is installed or uninstalled. Drupal 7 loads the functionality from “.install” file whenever the module is installed or uninstalled. We need to write hook functions “hook_install” and “hook_uninstall” in “.install” file. So, Drupal 7 will call these functions […]
In our previous article, we have created an empty ATL COM Project. Now we need to add our functionality to the project. Remember that we are going to create a COM component using ATL (Active Template Library). Most of the code for our project was generated by Visual Studio. Now we need to add our […]
We have discussed opening & reading from the file in our previous Article “C Programming – Dealing with files – How to read from a file?“. fwrite function Another important buffered function, ‘C’ provides is fwrite function. fwrite function writes to the file.

WordPress provides the flexibility to store revisions of posts. That means, WordPress stores the posts into post revisions whenever you modify the post. This really helps to retrieve the post information from post revisions when you miss some information in the current post. WordPress stores all the post revisions into the database like it stores […]
‘C#’ classes are code blocks that combine data and operations those work on the data. ‘C#’ classes enables Object Oriented Programming (OOP) concepts of encapsulation and abstraction. Encapsulation means combining data and the operations apply on the data together. Abstraction means hiding the details to outer world. ‘C#’ classes are created using the class keyword. Below […]
Active Template Library (ATL) is a lightweight library used to develop COM-based components using Visual C++. Through ATL we can quickly develop COM components or COM services. In this article, I am trying to explain the steps to create an ATL COM component using Microsoft Visual C++ and Microsoft Visual Studio 2012 IDE (Integrated Development […]
