Hello, I have a client/server apps i am building. The server has two features cDAQ and waveform generator. the server it goes to the waveform generator as a default mode intentionally. The client sends the command to change server from cDAQ to waveform. If i turn on the server it goes in waveform mode and collect data until the client tells it to switch. When I turn on the client in cDAQ mode, you see the waveform data first then youo get the cDAQ data. I was wondering if there is a way I can clear the buffer in the server once the client is on before it writes the data to the client. If run the code succesfully, you will notice the issue. The same thing would happen if I set the server to run first in Cdaq mode. Once I turn on the client in waveform mode, I will get cdaq data first the once the server receives the packet from the client i then get waveform data. You will notice a delay when the server switch from waveform to Cdaq. Suggestions are welcome. client name is: Mockup Client.vi server name is: NEW SERVER1.vi control type def is ALL data control.ctl Im using a cdaq9172 with 5 NI cards. the server is programmed to run like that only Admin Note - VIs removed per user's request.

Sorry, not yet. I have lots of "free time" on the weekend, but my students are keeping me busy during the week.
