Minimizes or maximizes the specified window, or returns it to normal.

void _WZoom(WHANDLE wh, int newstate)
WHANDLE wh;            /* Window handle. */
int newstate;                  /* State of window after zoom. */

Remarks

You can specify the newstate parameter as WZ_MINIMIZE, WZ_NORMAL, or WZ_MAXIMIZE, which are defined in the PRO_EXT.H file.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

Example

The following example creates and displays a window. It then calls _WZoom(В ) for this window with each possible parameter.
