I have a MyDialog dialogBox and it has MyTab control.

MyDialog.h file is

#include "MyTab.h"
class MyDialog: public CDialog
		{
virtual BOOL OnInitDialog();
private:
afx_msg void abc();	
static void MyFunction( int, unsigned int);
		
public:
MyTab m_cTab; //do this

}

MyDialog.cpp file is

bool  MyDialog::OnInitDialog()
{
CDialog::OnInitDialog();
	m_cTab.Init(); //here call to MyTab's method successfully.
}

and
MyTab .h file is

class MyTab :public CTabCtrl
{
void Init();
}

and MyTab.cpp file is

void MyTab::Init()
{
	// do something 	
			
}

I want to know how to call MyDialog class method that is abc() and MyFunction in MyTab class?
