Streaming with HSDIO continuously

Hi,

Anyone is familiar with HSDIO streaming? I really need help please.

I've been searching and found this example. https://decibel.ni.com/content/docs/DOC-29085

I can use this example to stream my TDMS waveforms which has much samples than buffer size of my HSDIO PXIe-6544.

The snippet in the link is totally wrong. But the code inside attached file is usefull for streaming. But the thing is, I can only stream my waveform one time only. How can I stream my waveform repeatedly? I've tried to change the option from single generation into loop continuously, but seems doesnt work. Maybe it needs a little bit manual work?

regards,

Yan
