Visual C++, MFC, Win32, etc., are from Microsoft and they are specific to develop software for Microsoft Windows.
If you need tools to write a cross platform program, have a look at the following URLs:

You won't be able to do that. MFC is for windows only. Anyway, even if your code was 100% system independant, you still would need to recompile it for a different platform (the binaries are totally different).
If you want to make something portable, you will need to make your code portable, you will need to get rid of every call to the win32 API (and get rid of MFC, completely). However, don't panic, there is a cross-platform alternative to MFC: wxWidgets[^]. If you have experience with MFC, it shouldn't be too difficult to switch because it is more or less similar (in usage I mean).
Good luck, it is probably more complicated than you think...

better look for library like WxWidget and QT for this, MFC is specific for windows.

Hello everyone,
I am designing a small budget assignment/checking application for a hierarchy organization structure. The purpose is to check and assign the budget for each employee not exceeds the total budget of a department.
The most difficult part is, a sub-department's total budget is not always lower than the upper level department's budget (i.e. the organization tree does not 100% reflects the relationship that father department node's budget is always more than that of child department node).
So, I put many exception rules to check in such situation. I am wondering whether there is any smarter ways to implement and represent the budget assignment and check model?
(I can re-write anything in this application, including data structure and algorithm, if the budget assignment and checking function is met.)
An example,
department goo under larger department foo, is represented as, /foo/goo, and /foo/zoo's budget is lower than /foo (this is a normal senses), but /foo/goo's budget is larger than /foo(this is a special rule, in the business model, even if goo under management of foo, its budget is not controlled by foo, so larger), and I maintain the remaining budget for each department,
for employee, /foo/emp1 and /foo/zoo/emp2, I can check from father node to child node for making all child nodes' budget not exceed father node, but for /foo/goo/emp3, I have to check specially. This is my headache.
If there are any smarter ways to represent the data structure and budget check, I would appreciated.
thanks in advance,
George

Hi CPallini,
How do you call a real project? This is an issue I met with in a C++ project, it is not homework. A couple of guys want to make something fun and cool.
Any ideas? Smart guy?

George

Traditionally this sort of thing is done with tables, often database tables. You might have one table with every budget holder listed and their budget and then one or more consolidation tables expressing the budget grouping rules. Without knowing the details of what you're doing it's difficult to say exactly how it will work best. You could construct the same sort of logical structure with indexed lists or multi-dimensional arrays, sparse arrays if you've got a high dimensional data set.
One key thing in all cases is to identify a 'budget holder' as a type of entity whether that is always a person or sometimes a department or company or whatever. You'll find the coding works out much easier if it has some way of directly representing this key role. The next step might be to identify the set of relationship between budget holders in your complex hierarchy and then try to represent each of those relationships unambigously either as a type or in terms of a data structure.
Don't be afraid to tear up the design and start agiain a few times. I'm sure you'll soon have an efficient mapping from the real world onto a C++ class structure and back again. Good luck

Thanks Matthew,
Do you mean using one table to store budget holder information, and mapping the related budget grouping rules to the budget holders, using data structures like indexed lists or multi-dimensional arrays, sparse arrays?

George

That's certainly one way you could do it.

Thanks Matthew,
Your insights give me more ideas. Now I make the algorithm in details and want to let you review and
comment. Sorry, I do not adope 100% of your ideas.
1. Any node can have multiple childs, for example, foo has goo and zoo as two childs;
2. If each child has its special money management system, I will put a special pointer to the money object, or else, it will share the same money source from parent (its money pointer points to the same money object of that of parent);
3. In the money object, it contains the pool of nodes which gets money from the object and how much each node gets from the money object, from total amount of money of the money object, and the consumed money by all the nodes, we can make sure how much remains;
4. When checking/assigning remaining budget for a specific child, traverse from the parent (root) of the tree to the specific child, and check its "money pointer" to see the remaining amount of money.
regards,
George

It sounds like it would work. It also sounds potentially complex so if it was me then one or more diagrams might be needed just to make sure.
When it comes to cleaning up the data structure it's important to be able to visit every node exactly once in order to delete them and not 'orphan' any nodes by deleting everything that refers to them before they're deleted or worse still try to delete something twice! If you can avoid that sort of problem I reckon you'll be fine. Don't forget to post an article when it's done

Everything has to be deleted eventually. I assume you're not allocating all these structures on the stack so you're eventually going to have to delete them. 'Linear Traversabiliy', being able to iterate through every node and reach each one exactly once, is a very important property to maintain in complex data structures. Deleting a non linear-traversable data structure reliably is potentially very nasty. Don't go there. Keep it as simple as it can be to do the job and it'll be fine.

Thanks Matthew,
1.
Do you mean each time, I establish the structure, and after each check/assignment, I delete the structure?
2.
Why I need to delete the structure? The structure remains the same, I just need to change the budget amount with budget assignment operation.
regards,
George
