The easiest thing is to make a global variable in you CView class .CPP file and use an extern in the dialog class .CPP file and place the value of the member variable in the shared variable. Example (which uses and int variable):<br />
<br />
In CVIEW.CPP:<br />
<br />
int ExampleVariable; // place at the top of the file under preprocessor definitions/#includes etc.<br />
<br />
<br />
In DIALOG.CPP:<br />
<br />
extern int ExampleVariable;// place at the top of the file under preprocessor definitions/#includes etc.<br />
.<br />
void DIALOGCLASS::SomeFunction ()<br />
{<br />
ExampleVariable = m_nMemberVariable; // m_nMemberVariable is a member variable of the DIALOGCLASS<br />
<br />
}<br />
<br />
<br />

share variables between CView and CDialog?
