virtual L_INT LWia::SetPropertySystemTime(pItem, pszID, uID, pValue)
Sets the time of the specified item as a form of SYSTEMTIME structure for WIA property type VT_UI2 | VT_VECTOR.
Valid pointer to a type IWiaItem (WIA Version 1.0) or IWiaItem2 (WIA Version 2.0) object, representing the item that has the property.
Retrieve this parameter by either calling the LWia::GetRootItem function to get a pointer to the device's root item, or by enumerating the child items of the device by calling LWia::EnumChildItems.
String pointer containing 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, the WIA toolkit will use the ID passed through the uID parameter; otherwise, the pszID parameter will be used regardless of whether a valid property ID is passed through the uID parameter.
The property ID of the property.
The uID parameter is required only if the pszID parameter is NULL. If the pszID parameter is not NULL, you can pass 0 for uID.
Pointer to a variable of type SYSTEMTIME to be set as the passed item's time.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This feature is available in LEADTOOLS version 16 or higher.
Call [LWia:SetPropertySystemTime to set the passed item's time through the SYSTEMTIME structure for any WIA property of type VT_UI2 | VT_VECTOR (for example, WIA_DPA_DEVICE_TIME or WIA_IPA_ITEM_TIME).
