IWiaDataTransfer::idtEnumWIA_FORMAT_INFO method (wia_xp.h)
The IWiaDataTransfer::idtEnumWIA_FORMAT_INFO method creates a banded transfer implementation of the IEnumWIA_FORMAT_INFO interface.
Syntax
HRESULT idtEnumWIA_FORMAT_INFO(
[out] IEnumWIA_FORMAT_INFO **ppEnum
);
Parameters
[out] ppEnum
Type: IEnumWIA_FORMAT_INFO**
Receives the address of a pointer to the IEnumWIA_FORMAT_INFO interface.
Return value
Type: HRESULT
If it fails for any reason other than those specified in the following table, this method will return a standard COM error.
| Return Value | Meaning |
|---|---|
| E_INVALIDARG | The ppEnum parameter is not the address of a pointer to the IEnumWIA_FORMAT_INFO interface. |
| E_OUTOFMEMORY | There is not enough memory to create the enumerator object. |
| S_OK | The enumerator object was successfully created. |
Remarks
This method creates the IEnumWIA_FORMAT_INFO interface that applications use to enumerate an array of WIA_FORMAT_INFO structures. This provides applications with the ability to determine the formats and media types of incoming data when transferring banded data.
Note that applications must call IUnknown::Release method on the interface pointers they receive through the ppEnum parameter.
