An interface is a contract, and it is set by declaring a set of functions in it. A class can implement these interfaces. This means, we assure that a class signing the interface give an implementation for the contract functions. In this example, we will study about C# Interfaces with Examples. It covers defining & implementing, extending, implement more than one & casting between them.
The Panel Container Control is all about this article. We will see how to use the panel control for grouping the controls. Then we will explore the important properties of this container along with an example.
Panel Container is almost like a group box. Unlike the group box, the panel does not have a title on the top. But it has the support to provide the scroll bars. These scroll bars allow us to place plenty of controls in it and make us to scroll when the form is not enough to fit all the controls.
When an owner window of the menu item decides how the menu item should look, then the menu item is known as Owner Drawn Menu. The default windows provided menu has a standard look and feel. We cannot add Red and blue-colored boxes as a menu item through the resource editor. In this Example, we will see how can we display only color boxes as a menu item under the color menu. Here, we will learn the need for the WM_DRAWITEM and WM_MEASUREITEM windows messages.
1. Introduction to GroupBox Control In this article, we will explore how to use the C# ‘GroupBox Control’ in C# windows forms-based applications. Before we start, we will learn about Topmost Container, Normal Container and Controls. The first fact one should know is that a Container holds Controls in it. For example, the Log-in dialog as a Container can hold username and password text boxes in it. A Container can act as […]
In this article, we will learn how to push C# debugging information into the Trace File and Windows Event Logger. This is useful when the application is deployed in the customer place. Debugging an application in customer place is almost not possible as we do not keep the source code in the deployed environment.
The screen-shot below shows our Example and you can download it from the link at the bottom of this article. Here, we will not explore how the application performs prime number summation. But, will learn how to perform tracing using the C# Application Programming Interface.
