MFC to call another class in a class of two dimensional array-CodePudding

As title, I'm in Ca class defines a two-dimensional array of strings in a.h
Public:
Cstrings Shuzu [100] [100].
And for the assignment of the elements in an array in the a.c pp,
Now I want to call in another class Cb elements in the array of values, how to implement?

CodePudding user response:

In class Cb find Ca first instance of the class

CodePudding user response:

reference 1st floor schlafenhamster response:

find Ca first in the class Cb class instances

Excuse me specific how to achieve this, I compare food, can be said that detailed some

CodePudding user response:

CA g____a=new CA ();

CB g____b;
G___b. XXX (g___a - & gt; String);
Something like this

CodePudding user response:

The Cb constructor
Cb: : Cb (Ca * pca)
{
M_pca=pca;
}

Cb: : aaa ()
{
Cstrings s=pca - & gt; Shuzu [1] [1].
}

CodePudding user response:

Cstrings Shuzu [100] [100]. Write a bit odd,
