GUI Programming in Visual C++?

...hi guys, for my A-Level computing coursework i need to design and implement a computerised system for a company or organisation. ive already choosen what im going to do, and what language im going to program it in. since i hate Microsoft Access.

question is is, ive done previous programming in C++ using Dev-C++. however i could only use the console window. this time i would like to produce a more "rounded" system with a GUI. would i be able to transfer my knowledge to programming GUI's or do i need to learn some more before i attempt it? bearing in mind i need to have a completed system by February/March time.

heres a copy of my previous years coursework, just to give you an idea of where im at in C++.

Code:

thanks,

Are you familiar with object oriented programming?

i know roughly what it is, using classes etc a bit like the struct command but with more potential.

i have 0 experience with it but if you feel it would be worth while im all ears. what do you have in mind?



ps. you get more marks for your solution, not necesarily more techy but for appropriateness.

> heres a copy of my previous years coursework, just to give you an idea of where im at in C++.
Who (or what) is teaching you C++?
That should have earned you a failing grade.

Your main() is 750 lines long, and contains goto statements. This is not a structured program.
At the very least, each of the top-level menu options should be a separate function.

There are many uses of system("some_cmd") to do various things.

There isn't a single class in any of the code. It's not really a C++ program if you don't have classes.

You could probably replace all the cin/cout stuff with printf/scanf from C and call it a C program.

> int monp1 = 0, monp2 = 0, monp3 = 0, monp4 = 0;
Ever consider
int days[6][4]
rather than having 24 separately named variables?

Code:

---

                  switch(bookings[i].day)
                  {
                  case 1:
                      switch(bookings[i].time)
                      {
                      case 1: monp1 += 1; break;

---

This huge double switch monster becomes
days[ bookings[i].day ][ bookings[i].time ] ++;

> int SaveBookersFile(booker*, int);
> int SaveBookers(booker*, int);
> int SaveBookingsFile(booking* , int);
Had you used any classes, these would be member functions of that class.

> for(i=1; i<=number_of_bookers; i++)
Arrays start at 0, so on the off chance that you have 50 bookings, the last one goes off into unallocated memory.

> day = atoi(buffer.c_str());
Lookup string streams.

> for(i=1; i==4; i++)
Huh?
This loop never runs, the test fails on the first pass.

i know the program ist up to your kind of standards Salem, it was only AS level work and it earned me a mediumish B grade. considering that i was the ONLY person programming mine, everybody else was using Microsoft Access, i recieved no formal teaching on C++ at all. so i think i did fairly good considering.

so you guys think i should stick with console applications for my next project then?

I suggest that you work through the book Accelerated C++. After that, other books mentioned in the C++ Book Recommendations thread would be good for you to read, especially Effective C++ (by Scott Meyers). Only after you have a good foundation in C++ should you think about having a GUI-based C++ program.

at last thank you Laserlight. i shouldnt have got carried away with myself wanting to make a program with all the bells and whistles before i could successfully write a decent program lol.

i guess ill just stick with the console window and brush up on my coding structure first,


thanks for ya help guys and gals...
