What my view displays is not redrawn once I move the thumb bar up or down past the hidden text ?
What should I add in to make it viewable when dragging the thumb downward or rightward ?

rc is declared as a global variable;

In OnDraw function

GetWindowRect(&rc);
pDC->LPToDP(&rc);
pDC->DrawText(L"Draw text",&rc,TA_LEFT);


In OninitialUpdate

CClientDC dc(this);
OnPrepareDC();
CSize sz(rc.With(),rc.Height());
dc.LPToDP(&sz);
SetScrollSizes(MM_TEXT,sz);

It's all about the cscrollview I use in my single document.

Thank you.
