void ShowCaret(hWnd)
This function shows the caret on the display at the caret's current position. Once shown, the caret begins flashing automatically.
The ShowCaret function shows the caret only if it has a current shape and has not been hidden two or more times in a row. If the caret is not owned by the given window, the caret is not shown. If the hWnd parameter is NULL, the SetCaret function shows the caret only if it is owned by a window in the current task.
Hiding the caret is accumulative. If the HideCaret function has been called five times in a row, ShowCaret must be called five times to show the caret.
| Parameter | Type/Description |
| hWnd | HWND Identifies the window that owns the caret, or is NULL to specify indirectly the owner window in the current task. |
None.
The caret is a shared resource. A window should show the caret only when it has the input focus or is active.
