How long does it take to learn how to write a "graphical interface + database" program?

Letter

Good teacher Mr. Ho. I am also in the self-study C + + read you write the Enlightenment one, feeling very big, thank you very much, I now do network operation and maintenance. will be exposed to some of the ERP content. , want to ask the teacher to guide. From just beginning to learn C + + to be able to write a graphical interface and simple interaction with the database, such a small program, assuming that the database is not considered a problem, how long it takes,?

Replies.

The first question of time. I think it varies from person to person. It depends on the personal accumulation, and the ability to learn. So I could not do for you to anticipate that in fact. It does vary from person to person.
When I saw your private messages on my cell phone yesterday. That's all that comes to mind. Today to open the computer to reply, think this is a very interesting question, say a little more.
As you ask, the underlying idea is what C + + has learned. The degree of mastery of the database, the ability to do a graphical interface to access the database program. You are already an industry person, in fact, such a school with the teacher in a course to learn the thinking, can adjust some.
Just to make a few simple programs, you can start to learn to do the graphical interface, by means of a tool called "Wizard". As well as visual design tools, I wrote the "C + +" form of "program Initiation (ii)" and "wxwidgets" in the "People Guidance" series "visual design with Wxsmith".

Have had such an initial experience. You will be able to complete the simplest application. This kind of feeling and the things that can not be understood from it will accelerate your study.

Of course, you don't think that's all. With the further study of C + +. You'll really know what those controls mean by dragging and dragging, and you can read the system-generated code until you can easily write more efficient UI code. Of course, in the process, the ability to apply the code for business logic is also improving.

The same is true of databases, with learning to practice. To do as the primary goal, with the existing experience, and then into the study. This "interaction" will speed up the learning process.
In this way, do not stick to the inherent pattern. By combining learning (cognition) and Learning (practice), you can quickly do what you want to do and become an expert at last.

I wish you a smooth study.
