VB6.Отправка изображений с помощью WinSock

Есть сервер на VB6. Этот сервер делает скриншоты экрана с определенной периодичностью и затем отсылает изображение с помощью WinSock клиенту. Клиент написан на C#. Проблема в том,что при обработке сообщения на стороне клиента возникает исключение "Недопустимый параметр".Отправляю изображение как Winsock.SendData CaptureScreen()

Код скриншота:

Была идея перевода изображения в байты, но найти пример не удалось.
