SAP Data Object
The SAP Data Object is a special object for purposes of data transport. This object is used in
drag and drop and clipboard operations. The SAP Data Object implements an automation and an IDataObject interface. The IDataObject interface is a standard OLE interface for data object manipulation. The automation interface displays the following methods:
Name |
Parameters |
Return Type |
Description | |
GetData |
Long Variant |
cfFormat vaData |
void |
Retrieves data from the data object in the specified format |
SetData |
Long Variant |
cfFormat vaData |
void |
Stores data in the data object in the specified format |
IsFormatAvailable |
Long |
cfFormat |
Boolean |
Returns TRUE if the data object contains data in the specified format |
SetData may specify a format which is not initially cached in the data object. Since the data object does not interpret the data in any way, the data may be of any clipboard format. The variant data type must be any data type which is transportable to other processes. Therefore, object may not be stored in the data object.
Valid formats are: char, short, long, String, Date, Time, Boolean and safe arrays of these types.
