Create global variables to save data from different windows in MFC

The format is as follows:

Data_temp.h

Class Cdata_temp
{
Public
Cdata_temp ();
Virtual ~cdata_temp ();
Public
Staticint int_temp;//must be defined as a static type.
static char char_temp;
Staticcstring str_temp;
};

Data_temp. Cpp

#include "stdafx.h"
#include "Data_temp.h"

The initialization of the member function must be done, and it should be in this format, cannot be initialized in the constructor, if there is no initialization, there will be "unresolved errors";
Char cdata_temp::char_temp= ';
CString cdata_temp::str_temp ("");
int cdata_temp::int_temp=0;

Cdata_temp::cdata_temp ()
{

}
Cdata_temp::~cdata_temp ()
{

}

Finally, you only need to #includ "Data-temp" in the header file of the project name. H
