Modeles , Modal dialog window and variable

[C++ Programming]

How do give ( pass, transmit) value of variable
m_sPP_modal
From class modal window “CAdodc_MDI”
To variable
m_sPP_modeless
of modeless class “CMyModeless2”
and on the contrary - from class “CMyModeless2”
to class modal window “CAdodc_MDI ?

below 2 lines isn’t correctly into button ‘OK’ of modal window:
CMyModeless2 dlg2;
dlg2.m_sPP_modeless = L“text”;

below brief:
