_WShow( ) API Library Routine


void _WShow(WHANDLE wh) WHANDLE wh; /* Window handle. */

When you create a window, it is hidden by default until you use _WShow( ) to make it visible.

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 contains two API routines. WINOPEN( ) opens a window but doesn't call _WShow( ), illustrating that the window is hidden until _WShow( ) displays it on the screen.

Copy Code

#include <pro_ext.h>
FAR WOpen(ParamBlk FAR *parm)
{
   _RetInt(_WOpen(2, 2, 20, 70, WEVENT | CLOSE, WINDOW_SCHEME,
      (Scheme FAR *) 0, WO_SYSTEMBORDER), 10);
}
FAR WShow(ParamBlk FAR *parm)
{
   _WShow(parm->p[0].val.ev_long);
}
FoxInfo myFoxInfo[] = {
   {"WOPEN", (FPFI) WOpen, 0, ""},
   {"WSHOW", (FPFI) WShow, 1, "I"},
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
