High timer experts,:omg: I have a problem very similar to the "Help clock generate" thread. I want to control a stepper motor of an electrophoresis unit. The Motor should be driven with (only) 250 hz. The low precicion timers using the message que (windows.froms.timers) are not usefull for this purpose (Instantly I wandered why the motor does not perform all steps with the timer set to 50 Hz, but meassuring the intervals using the system performancecounter revealed, that about every 10th interval is only 203 ticks long -- for what ever reason) Looking for a solution, I came accross -Queue timers- which should be able to deal with this problem. Unfortunately, I am not familiar with C programming language and all the examples were written in C (e.g. here). Is there a possibility to run such a timer from VB.net? Thanks in advance Armin
