Hey Pratapa,
I am not sure I can help you "append data" to your custom action. However,
here is what I do to read the data from the stream being passed to the
deferred custom action.
HRESULT hr = S_OK;
UINT er = ERROR_SUCCESS;
BOOL isTurnedOn = FALSE;
LPWSTR pwzAuthCabPath = NULL;
HANDLE hFile = INVALID_HANDLE_VALUE;
LPWSTR pwzCustomActionData = NULL;
LPBYTE pbData = NULL;
DWORD_PTR cbData = 0;
DWORD cbWritten = 0;
hr = WcaInitialize(hInstall, "ConfigureMU");
ExitOnFailure(hr, "failed to initialize ConfigureMU");
// get temporary path for extracted file
StrAlloc(&pwzAuthCabPath, MAX_PATH);
ExitOnFailure(hr, "Failed to allocate temporary path");
::GetTempPathW(MAX_PATH, pwzAuthCabPath);
hr = ::StringCchCatW(pwzAuthCabPath, MAX_PATH, L"muauth.cab");
ExitOnFailure(hr, "Failed to append filename.");
hr = WcaGetProperty( L"CustomActionData", &pwzCustomActionData);
ExitOnFailure(hr, "failed to get CustomActionData");
* //Get the stream for the custom action data.
hr = WcaReadStreamFromCaData(&pwzCustomActionData, &pbData, &cbData);
ExitOnFailure(hr, "failed to read file contents from custom action
data");*
