IWMDMStorageControl2::Insert2
The Insert2 method inserts content into a storage medium. The difference between IWMDMStorageControl::Insert and IWMDMStorageControl2::Insert2 is that the Insert2 method also enables you to set the name of the destination file. Using this method, an application can pass an Iunknown interface of any custom COM object to the secure content provider. This makes it possible to pass custom information from an application to a secure content provider if the application has sufficient information about the secure content provider.
Syntax
HRESULT Insert2(
UINT fuMode,
LPWSTR pwszFileSource,
LPWSTR pwszFileDest,
IWMDMOperation* pOperation,
IWMDMProgress* pProgress,
IUnknown* pUnknown,
IWMDMStorage** ppNewObject
);
Parameters
fuMode
[in] Processing mode used for the Insert2 operation. The following table lists the processing modes that can be specified in the fuMode parameter. You must specify exactly one of the first two modes, exactly one of the STORAGECONTROL modes, and exactly one of the CONTENT modes. If both WMDM_MODE_BLOCK and WMDM_MODE_THREAD are specified*,* block mode is used.
Mode | Description |
WMDM_MODE_BLOCK | The operation will be performed using block mode processing. The call will not return until the operation is finished. |
WMDM_MODE_THREAD | The operation will be performed using thread mode processing. The call will return immediately, and the operation will be performed in a background thread. |
WMDM_MODE_QUERY | A test will be performed to determine whether the insert operation could succeed, but the insert will not be performed. |
WMDM_STORAGECONTROL_INSERTBEFORE | The object will be inserted before the target object. |
WMDM_STORAGECONTROL_INSERTAFTER | The object will be inserted after the target object. |
WMDM_FILE_CREATE_OVERWRITE | The object will replace the target object. |
WMDM_CONTENT_FILE | The content being inserted is a file. |
WMDM_CONTENT_FOLDER | The content being inserted is a folder. |
WMDM_CONTENT_OPERATIONINTERFACE | The content being inserted is an operation interface. The data for the content should be written to the application-implemented IWMDMOperation interface. |
WMDM_MODE_PROGRESS | The insertion is in progress. |
WMDM_MODE_TRANSFER_PROTECTED | The insertion is in protected transfer mode. |
WMDM_MODE_TRANSFER_UNPROTECTED | The insertion is in unprotected transfer mode. |
pwszFileSource
[in] Pointer to a (Unicode) wide-character null-terminated string indicating where to find the content for the insert operation. This parameter must be NULL if WMDM_CONTENT_OPERATIONINTERFACE is specified in fuMode.
pwszFileDest
[in] Name of output file.
pOperation
[in] Pointer to an IWMDMOperation interface, an optional set of methods used to enhance the transfer of content to a media device. This parameter must be NULL if WMDM_CONTENT_FILE or WMDM_CONTENT_FOLDER is specified in fuMode.
pProgress
[in] Pointer to an IWMDMProgress interface to be used by Windows Media Device Manager to report progress back to the application. This parameter can be NULL.
pUnknown
[in] IUnknown pointer to be passed to the secure content provider.
ppNewObject
[out] Pointer to an IWMDMStorage interface that will contain the new content. This parameter can be set to NULL.
Return Values
The method returns an HRESULT. All the interface methods in Windows Media Device Manager and service provider can return any of the following classes of error codes:
- Standard COM error codes
- Windows error codes converted to HRESULT values
- Windows Media Device Manager error codes
For a complete list of possible error codes, see Error Codes.
Possible values include, but are not limited to, those in the following table.
Return code | Description |
S_OK | The method succeeded. |
WMDM_E_INTERFACEDEAD | The file or folder was previously deleted. |
WMDM_E_NORIGHTS | The caller does not have the rights required to perform the requested operation. |
E_BUSY | The media device is already busy with another operation. |
E_INVALIDARG | Some of the input parameters are invalid or NULL. |
E_FAIL | An unspecified error occurred. |
WMDM_E_NOTCERTIFIED | The caller is not certified |
WMDM_E_MAC_CHECK_FAILED | The message authentication check failed. |
Remarks
When using WMDM_MODE_THREAD, call IWMDMDevice::GetStatus after each file transfer to check for WMDM_STATUS_READY. This ensures the file operation is finished.
If an application uses WMDM_MODE_THREAD and passes a non-null pProgress parameter, the application must ensure that the object to which pProgress belongs is not destroyed until the read operation completes, because Windows Media Device Manager will send progress notifications to this object. This object can be destroyed only after it receives End notification. Failure to do this will result in access violations.
