To achieve a simple chat function, the background for the transparent
HBRUSH gets=CDialog: : OnCtlColor (pDC, pWnd, nCtlColor);
PDC - & gt; SetBkMode (TRANSPARENT);
Gets=(HBRUSH) GetStockObject (NULL_BRUSH);
And then refresh the word began to overlap
Also met this situation before with the following code to solve the
CRect the rect.
GetDlgItem (IDC_XXXX - & gt; GetWindowRect (the rect);
The ScreenToClient (the rect);
The InvalidateRect (the rect);
M_xxx. SetSel (0, 1);
M_xxx. ReplaceSel (cstrings);
Results now useless
Access to the Internet found another string of code also pretty useful
GetDlgItem (IDC_XXXX) - & gt; ShowWindow (SW_HIDE);
GetDlgItem (IDC_XXXXX) - & gt; SetWindowText (cstrings);
GetDlgItem (IDC_XXXX) - & gt; ShowWindow (SW_SHOW);
Well,,, it is useful at the beginning, until after the writing brush has been sent to the bottom bottom brace not actively decline, I looked at it manually pull down, below the overlap again, and when I back brace on heaps, also began to overlap above! Again your refresh
Pray god to help

The background erase you deleted, the last of the output text, can't erase, will overlap,

GetDlgItem (IDC_XXXXX) - & gt; SetWindowText (cstrings);
GetDlgItem (IDC_XXXX) - & gt; ShowWindow (SW_SHOW);
Hide and show the way, it is can solve the problem of data overlap, but if it is updated in real time data will be flashing ~
