Thank jjmckenzie for your answer, but richedit doesn't help. I can see every message from lineedit below: Code: trace:edit:EditWndProc_common hwnd=0x50150 msg=102 (WM_CHAR) wparam=66 lparam=210001 trace:edit:EDIT_EM_ReplaceSel L"f", can_undo 1, send_update 1 trace:edit:EDIT_EM_ReplaceSel inserting stuff (tl 35, strl 1, selstart 35 (L""), text L"vgfgdfgdfgdfgdfgdgdfgdfgdfgdfgdfgdg") trace:edit:EDIT_UpdateText notification EN_UPDATE sent to hwnd=0x3013e trace:edit:EDIT_SetCaretPos 36 - 194x0 trace:edit:EDIT_EM_ReplaceSel notification EN_CHANGE sent to hwnd=0x3013e trace:edit:EditWndProc_common hwnd=0x50150 msg=102 (WM_CHAR) -- 0x00000001 trace:edit:EditWndProc_common hwnd=0x50150 msg=f (WM_PAINT) wparam=0 lparam=0 trace:edit:EditWndProc_common hwnd=0x50150 msg=14 (WM_ERASEBKGND) wparam=a60 lparam=0 trace:edit:EditWndProc_common hwnd=0x50150 msg=14 (WM_ERASEBKGND) -- 0x00000001 but textedit doesn't show any message in debug output. In fact it's chat so lineedit + textedit under. I'm trying gather text from pokerstar client. There's screenshot: [Image: http://www.24-7pressrelease.com/attachments/011/press_release_distribution_0111871_14143.jpg ] any other idea? Thanks
