LVectorDialog::DoModalVectorViewMode

#include "ltwrappr.h"

virtual L_INT LVectorDialog::DoModalVectorViewMode(hWndParent=NULL, pnViewMode=NULL);

Brings up the Vector View Mode dialog.

Parameters

HWND hWndParent

Handle of the window that owns the dialog.

L_INT *pnViewMode

Pointer to an L_INT variable that contains a view mode value. The value present in the L_INT variable when the function is called is used to initialize the dialog. If this parameter is NULL when the function is called, the value used to initialize the dialog will come from the vector handle. When this function returns, if this parameter is not NULL, the variable pointed to by pnViewMode is updated with the value entered through the dialog.

Returns

Value Meaning
