You can also use Inter Process Communication between two dialog boxes. Read about OnCopyData method.

The SendMessage for WM_COPYDATA, they Handle to sender is an HWND

SendMessage((HWND) hWnd, // handle to destination window
WM_COPYDATA, // message to send
(WPARAM) wParam, // handle to window (HWND)
(LPARAM) lParam // data (PCOPYDATASTRUCT)
);
I hope this ll help you.

Answer / shiva

using application class we can store the data then we can retrieve that data example
if you're application like
in MyTabapplication.h
bool courses[3];
then dailog class
tab1.cpp
we can pass the data
void CTabOne::OnBnClickedCheck1()
{
// TODO: Add your control notification handler code here
UpdateData(TRUE);
CMyTabExampleApp* myApp = (CMyTabExampleApp*)AfxGetApp();
myApp->courses[0] = m_CHK_EXE.GetCheck();
}
tab2.cpp
in you're 2 dailog box
CMyTabExampleApp* myApp = (CMyTabExampleApp*)AfxGetApp();
if(myApp->courses[0])
{
m_CHK_EXE.EnableWindow(TRUE);
//m_CHK_EXE.SetCheck(FALSE);
}
