HRESULT RemoveStorageFileName(
   REFCLSID       clsidCaller,
   LPCWSTR       *pszKeyName,
   BOOL           fDeleteFile
);

Parameters

fDeleteFile

[in] Value specifying if the file should be deleted. TRUE deletes the file afterward; FALSE does not.

Return values

Value	Description
S_OK	Function completed successfully.
E_INVALIDARG	pszKeyName is invalid or bad.
SPERR_UNINITIALIZED	Either the data key or token delegate interface is not initialized.
SPERR_TOKEN_DELETED	Key has been deleted.
FAILED(hr)	Appropriate error message.

Example

The following code snippet creates a test file, removes it and manually deletes it. It may also have been deleted automatically by setting fDeleteFile to TRUE.

// Declare local identifiers:
HRESULT                   hr = S_OK;
CComPtr<ISpObjectToken>   cpObjectToken;
GUID                      guid0;
WCHAR                     *cpFileName;
ULONG                     CSIDL_LOCAL_APPDATA = 28;
ULONG                     CSIDL_FLAG_CREATE = 32768;

// Get the default text-to-speech engine token.
hr = SpGetDefaultTokenFromCategoryId(SPCAT_VOICES, &cpObjectToken;);

if (SUCCEEDED (hr))
{
   hr = CoCreateGuid(&guid0;);
}

if (SUCCEEDED (hr))
{
   // Create file with default format and store it in folder that
   // contains application-specific data that does not roam.
   hr = cpObjectToken->GetStorageFileName(guid0, L"TestFile", NULL, CSIDL_FLAG_CREATE|CSIDL_LOCAL_APPDATA, &cpFileName;);
}

if (SUCCEEDED (hr))
{
   // Remove object token.
   hr = cpObjectToken->RemoveStorageFileName(guid0, L"TestFile", false);
}

if (SUCCEEDED(hr))
{
   // Do stuff here.
}
