_WTopP( ) API Library Routine


unsigned int _WTopP(WHANDLE wh) WHANDLE wh; /* Window handle. */

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

The following example displays the position of the active window in pixels.
