Example for timer control initialization programmatically ?

[phy]

In user interface it is easy to generate the timer control callback, but how to make it work programmatically with Newctrl and etc. functions ? Is there available example how to do this ? I'm using Labwindows 4.0.1 version.

I attach a simple project that creates a timer programmatically and uses it to flash a led on a panel. You can use it as a skeleton for you needs.

I've just knocked this code up which might help you out...

If not, let me know...

Note: This was done with CVI 5.5 so I hope it works for 4.0.1.
