VB .net High Resolution Event Timer

Hi - I am trying to code up in VB (without measurement studio) a serial message that is transmitted consistently every 10 mili-seconds using NI's USB-RS422 converter. I'm having a problem with the VB event timer since it only has resolution in the 55 mili-second realm. My OS is W2K. Any suggestions on how to handle this? Thanks in advamce, Gary

Hi Gary

It reads like your problem is with the Visual Basic timer. You might want to check out their support site . Please post back if you have any trouble with the NI converter.

Thanks Russell. Yes it is with the VB timer resolution.

However I was looking for a NI suggestion on addressing this problem. I'm sure this has been encountered before and was hoping for any lessons learned or recommendations on what works or doesn't work. I didn't find any search results in the NI Developer Zone so maybe this is something new. - Gary
