The WS_TABSTOP Style
The TAB key and SHIFT+TAB keys have no effect when the controls in the dialog box do not have the
WS_TABSTOP style. Windows looks for this style as it searches for the next control
in the dialog box to receive the input focus.
When the user presses TAB or SHIFT+TAB, Windows first determines whether the control having the input focus
processes these keys. It sends the control a WM_GETDLGCODE message, and if the control returns DLGC_WANTTAB, Windows passes the keys to
the control. Otherwise, Windows uses the GetNextDlgTabItem function to locate the next control that is visible, not disabled, and that
has the WS_TABSTOP style. The search starts with the control currently having
the input focus and proceeds in the order in which the controls were created  that is, the order in which they are defined in the dialog box template. When
the system locates a control having the required characteristics, Windows
moves the input focus to it.
An application can also use GetNextDlgTabItem to locate controls having the WS_TABSTOP style. The function retrieves the
window handle of the next or previous control having the WS_TABSTOP style without
moving the input focus.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
