Hey, hello, everyone! I'm crazycatjack. Today I would say a few C language skills commonly used in embedded development. Maybe you've used it before, maybe you've just seen it, but you don't understand it in depth. Well, let's just add it today, ^_^.

Recently doing a project, need to use the Wait form, under devexpress There are splashscreen controls can be used, but also have progressindicator control can be used, but if not developed with Dev, we need to customize a waiting form.First, put it

Think of the database first with MySQL, this thing small and easy to install. In front of the web learned a little, now learn WinForm. Database First look at the convenient MySQL.Download a mysql5.7 version of, loaded on incredibly find password,

Combined with many of the previous studies, wrote a small program. sessions, custom scroll bars, CSS, and more. Small program does not use the database, mainly do not know which to use, and later. Login is also simple, you can enter the user
