Hello  ,
I have defined a two dimensional array of type double in one of my MFC classes
in class 1:
double m_aCoefficients[10][20];
and now I want to make a pointer to this variable in another of my classes and assign address of this double array to that pointer.
so i have defined in class 2:
double* m_pCoefficients[10][20];
and in my CMyDoc Class I have tried this:
m_Class2.m_pCoefficients = (double*[10][20]) &m_Class1.m_aCoefficients;
but it gives error
Error 4 error C2440: 'type cast' : cannot convert from 'double (*)[10][20]' to 'double *[10][20]'
How can I resolve this?
thanks

Here you should have
double (*m_pCoefficients)[20];
After this you can write
m_Class2.m_pCoefficients = m_Class1.m_aCoefficients;
I hope it helps..
Regards,
Sandip.

A is not a string, it is an array of 100 CString objects.

What is the problem ? You need to assign it at a certain position in your array, something like:
A[10] = B;

Yes If B have some Values like "a","b","c".... then i want to store these values in A[10].I need some line of code..
Plz give me..
Thanks in Advance

Hi,
You may be mistaken about CString.
You can store a variable in CString object.
CString string = "Test String";
If you want to copy CString A to B;
Do CString A = "Test String";
CString B;
B = A;
Thats it..
The price of anything is the amount of life you exchange for it.
Thanks and Regards.

CString a[100];
CString b;
b = "As";
a[0] = b;
b = "Cs";
a[1] = b;
BTW probably a good C/C++ tutorial is needed.

 I gave you code in my previous reply. Do you know what a CString class does ? You know that you can actually store a full string (e.g. "Hello") in a CString object ? So, when you have something like CString A[100], it actually means that you have an array of 100 CString objects (so, each one containing a separate string).
If you still don't know what to do, then please reformat your question because I don't get it.

My first reply gave you an example. Just store the string where you want in the array, what is the problem with that ? Did you try the code I gave you ?

Thx's I am try to do through that.

I guess the problem is that you don't understand the basics of C++. You don't have 2 strings, you have 101 strings: 100 are in a array (A) and one is alone (B). Please, review the basis and understand what an array is and what a CString is.

It would be much more easy for us if you explain EXACTLY what you are trying to do, because for now it doesn't make any sense to me.

 Oh my god. Is it a joke ? It's the third time you ask that and I gave you code in my first reply already.

Thanks very much for help like that...

1. That's exactly what you asked for.
2. If you don't recognise this as code you should reconsider your career choice.

Your sarcasm is highly inappropriate. Cedric (and others) spent a lot of time trying to help you but you're simply too dense to understand.

How can you expect people to give you an answer when you can't even ask a proper question.
You asked this: "I have two string CString A[100]and CString B.I want to store variable of B in A".
The code I gave you does what you are asking for, so why do you still complain ? I asked you several time to rephrase your question properly, is it my fault if you can't express yourself ? If the code I gave you is not what you are looking for, then why do you continue asking exactly the same question over and over ?

ok i accept it's my fault...
Can i continue..IF yes the reply me.I will try to do more specific..
