Gegenteil von WM_NextDlgCtl

[DeddyH]

Zitat von MS-SDK:

WM_NEXTDLGCTL
wCtlFocus = wParam; // identifies control for focus
fHandle = (BOOL) LOWORD(lParam); // wParam handle flag

wCtlFocus

Value of wParam. If the fHandle parameter is TRUE, the wCtlFocus parameter identifies the control that receives the focus. If fHandle is FALSE, wCtlFocus is a flag that indicates whether the next or previous control with the WS_TABSTOP style receives the focus. If wCtlFocus is zero, the next control receives the focus; otherwise, the previous control with the WS_TABSTOP style receives the focus.

fHandle

Value of lParam. Contains a flag that indicates how Windows uses the wCtlFocus parameter. If the fHandle parameter is TRUE, wCtlFocus is a handle associated with the control that receives the focus; otherwise, wCtlFocus is a flag that indicates whether the next or previous control with the WS_TABSTOP style receives the focus.
