The ShowCaret function makes the caret visible on the screen at the caret's current position. When the caret becomes visible, it begins flashing automatically.
BOOL ShowCaret(
| HWND hWnd | // handle of window with caret |
| ); |
Parameters
hWnd
Identifies the window that owns the caret. If this parameter is NULL, ShowCaret searches the current task for the window that owns the caret.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
ShowCaret shows the caret only if the specified window owns the caret, the caret has a shape, and the caret has not been hidden two or more times in a row. If one or more of these conditions is not met, ShowCaret does nothing and returns FALSE.
Hiding is cumulative. If your application calls HideCaret five times in a row, it must also call ShowCaret five times before the caret reappears.
The caret is a shared resource; there is only one caret in the system. A window should show a caret only when the window has the keyboard focus or is active.
