Visual C # is a new generation of procedures issued by Microsoft, an important part of the Microsoft .NET framework. The screen saver is a standard Windows executor with SCR's extension. The screen saver can not only extend the life of the display, but also protect private information. This article introduces you a dynamic text and graphic screen saver written in C # on a .NET platform. 1. Specific implementation steps: (1) New C #'s Windows application project under Visual Studio.Net, you may be named Screen_Saver. (2) Now we will design the main interface of the program: Set the name property of the form to Screen, the text property setting is empty, the BackColor property is set to Black, the size property is set to (800, 600), Controlbox, MaximizeBox, MinimizeBox The showintaskbar property settings are false, and the FormBorderstyle property is set to None. Add the Label control, the PictureBox control, and each of the Timer controls. Set the Name of the Label control to Word, the Text property is set to Picture1, the image is set to a predictive picture; set the Name of the Timer control to True, the interval property is set to 5. (3) Now let's start writing the full program code section:
