LVectorDialog::DoModalVectorViewMode

#include "ltwrappr.h"

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

HWND hWndParent;	window handle
L_INT *pnViewMode;	view mode

Brings up the Vector View Mode dialog.

Parameter	Description
hWndParent	Handle of the window that owns the dialog.
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

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
