I'd like to write a function that tells me how many documents I have open of a particular document type. I want to call this function whenever someone tries to open a new document and if that would exceed the predefined number allowed, notify them with a message box.

If you are dealing with MDI application in MFC using CMultiDocTemplate class, then I think you should use its members in this manner:
CMutiDocTemplate * t = ...; // the template for given document type
int total_documents = 0;
POSITION pos = t->GetFirstDocPosition();
while(pos != NULL)
pos = t->GetNextDoc(pos);
I am havin problems doing this c++ project.Its in regards to whether i can use one main class (e.g.main.cpp) or have to use a few classes.I am also a bit weak when it comes to c++ as java is my main language so any hints on the code or how to go about doing this would be great.The basic idea is :
Create a class called DataSet that stores a vector of floating-point values. Give this vector an initial size of zero, and use the push_back operation to add new elements.
The DataSet class should have a public member function for each of the operations described above, as well as a member function that adds an element to the vector.
I have to get the MEAN,MEDIAN and Standard Deviation.
I would very much appreciate if you could help me asap as I am desperately stuck.
It looks as though you have indeed started, and are well on your way.
iv tried but get nothing but errors.
On a side note, you might want to update your post so that it is more readable (you'll get tons more help if folks don't have to squint their eyes and turn their head sideways to make sense of it all). Use the <pre> tags to surround the code and make sure the angle brackets are formatted correctly. The Preview button helps in this capacity.

ok sorry, im only fairly new at this.the project seems pretty basic but I just cannot do this at all.Could you give me the code or an idea on how to do this even,which would be a huge help: Create a class called DataSet that stores a vector of floating-point values. Give this vector an initial size of zero, and use the push_back operation to add new elements
I just cannot get my head around this.From the input file I have to get the Mean,Median and standard deviation.The code I have used which I took from another c++ project I have done,is incorrect i think
