automatic system standby generation and resume after few seconds?

Is this one possible? If so how to achieve this?

This has already been answered. Use the timers.

No i tried with mike example. Only suspend state is happening. It's not wakingup.

What i have to change in that vi? Please kindly help in this regard.

Thanks,

I tried the VI. It worked on my system, which isn't too surprising since the VB code I pointed out works. The monitor did not turn back on, but I don't think that's because of the system call. I suspect that has to do with the power-saving features of the monitor. I did make one small change, though, which was to provide a control for the number of seconds to wait:

You should try the VI on another system. Like I said, the standby and hibernate operations don't always work properly because of BIOS and ACPI interactions.

Hi mathan,
could a reboot of your system, be a solution for you?

Dear smercurio, It's working now but.....

The monitor did not turn back on, but I don't think that's because of the system call. I suspect that has to do with the power-saving features of the monitor. You should try the VI on another system.

Yes i tried on some  5 systems and everywhere i observed that:

       For the specified time delay say some 5 seconds the vi is working fine but only the monitor didn't turn back on to the normal state. I asked my superior to check for monitor settings.

       Also if i give a delay more than 10 seconds, the suspend and resume operation happens immediately and no delay was there. why such a behaviour?

Thanks,

No mike. Specifically i need to implement suspend and resume operation. This is basically required to test my USB device.

Thanks,

Dears,

Actually i thought of simulating a key press or mouse click automatically (programmatically) after the system enters resume state.

will it be ok? how to achieve this?

[Edited: I thought this because my systems gotback to resume state without any problem but monitor only needs external disturbance to get activated]

Hi mathan,

i´m not sure if this will work if the pc is in standby mode, but here is an example.
Hope it helps.

Dear mike,

Could you please post these 2 controls please.

user32.key_updownclick.ctl
user32.virtualkeycodes.ctl

Thanks,

Mathan

Hi mathan,

yes i can, here they are. But you could use the vi´s also without them, right click on the control/constant/indicator and select "disconnect from typedef".
