在VB中创建屏幕上的标尺 [英] Creating a on screen ruler in VB

问题描述

我如何在VB中创建一个屏幕标尺，这样你按一个按钮然后你点击a点然后点b并显示长度（以像素为单位），请理解我已经在VB编程了虽然只是通过在互联网上学习和学习来学习，这是我的热情。我仍然是一个在学校的青少年，另外四分之一的人在他们的击球手中非常小，例如打破需要做的事情，但我想要更多的帮助

How would I go about creating a onscreen ruler in VB so you press a button and then you click point a and then point b and it shows the length in pixels, please be understanding as I've been programming in VB for a while but only learnt off by mucking around and learning in the internet and this is my passion. I am still a teen at school and the folks over on another fourm were very minimal in their awnsers such as "break down what needs to be done" but I would like some more help
