User Controls


Code Snipets



Other stuff


Gest Book



Welcome, this page is dedicated to Visual Basic, I want to focus this page in user Controls  and Class because it is a very important feature  and way of modern programming.

With Class and User Controls you can reuse your code.

Here's a practical example, when we need the user to input a number in a text box we basically write some code in the KeyPress event of the textbox to ignore values that are not numeric. Simple, but in a project that you need this future in a lot of different fields and forms you will have to do a lot of copy and paste to do this, not to mention a unnecessary multiplication of the same lines in different places of you project. The way to make a numeric only textbox described above as you guessed is the wrong way, the "Wright" way is to write either a class that handles the events of a textbox or user control so that you can reuse your code
in your projects. Hey I am a programmer, if a task is repetitive I just write some code that does some of the boring work for me!
