#include "ltwia.h"

L_LTWIA_API L_INT EXT_FUNCTION L_WiaSetPropertySystemTime(hSession, pItem, pszID, uID, pValue)

HWIASESSION hSession;	/* handle to an existing WIA session */
L_VOID* pItem;	/* pointer to IWiaItem or IWiaItem2 interface */
L_TCHAR* pszID;	/* pointer to string array that represents the equivalent property ID string */
L_UINT32 uID;	/* property ID */
LPSYSTEMTIME pValue;	/* pointer to valid SYSTEMTIME structure to be set */

Sets the time of the specified item as a form of SYSTEMTIME structure for WIA property type VT_UI2 | VT_VECTOR.

Parameter	Description
hSession	Handle to an existing WIA session. This handle is obtained by calling the L_WiaInitSession function.
pItem	Valid pointer to a type IWiaItem or IWiaItem2 object (IWiaItem if using WIA Version 1.0; IWiaItem2 if using WIA Version 2.0), which represents the item having the property.
	You can retrieve this parameter by either calling the L_WiaGetRootItem function to get a pointer to the device's root item or by enumerating the child items of the device through a call to L_WiaEnumChildItems.
pszID	This string pointer should contain the equivalent property ID string for the WIA property ID (see example below):
	Property ID	Property ID Equivalent String
	WIA_IPA_TYMED	WIA_IPA_TYMED_STR or "Media Type"
	WIA_IPA_DEPTH	WIA_IPA_DEPTH_STR or "Bits Per Pixel"
	If this parameter is NULL then the WIA toolkit will use the ID passed through the uID parameter, otherwise the pszID parameter will be used whether or not you passed valid property ID through the uID parameter.
uID	The property ID of the property.
	This parameter is required only if the pszID parameter is NULL, otherwise you can pass 0 for this parameter.
pValue	Pointer to a variable of type SYSTEMTIME to be set as the passed items time.

Returns

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

Comments

This feature is available in version 16 or higher.

Call this function to set the passed items time through the SYSTEMTIME structure for any WIA property of type VT_UI2 | VT_VECTOR (for instance, WIA_DPA_DEVICE_TIME, WIA_IPA_ITEM_TIME).
