It has already used C programming for more than 5 years, although I definitely call yourself very familiar with C , but now I have to change the language to write a program is really not very habit. Recently, I have to be a procedure, mainly management, it seems that RAD like C #, VB is to develop, but when I really start trying to write code, I found that many places are different from the use of VC writing programs. . For example, in the VC, you can define a window, put some controls in this window, and then put this window as another window in another window, but I don't know how to implement such an operation in C #. Very confusion, final decision or use VC to write the program. Hey, it's hard to go back.
