Here is something that I think could be modified for your purpose. It was designed for lab stations that have corporate mandated inactivity lockout, causing you to have

to login to the workstation again if you leave it unattended for a period of time.

Thank you very much for the tips, I will be trying them next week when I am back form my work trip!

Hi,

I have been breaking my head on this function for my program.

The function is that after for example a time of 10 minutes in which nothing on the front panel has been touched by a user,

a tab control should jump to tab 3.

Because the program constantly runs a webcam capture loop, I can not use modules that cause wait time etc.

Does anyone of you smart guys know the answer?

Thanks!

You could have used the Boolean XControl

You can change every button of a radio button (right click on border, select advanced, customize)

Thank you, the radio buttons were the solution.

Hi,

I am almost finishing my project, but I still have a question.

I designed 4 special big (4x 8 cm) buttons with and image on them.

These are normal Boolean buttons. At this point multiple buttons can be enabled at the same time,

but my requirement is that only one button can be enabled at the same time.

When pressing one, the other enabled button should turn off.

How to do this? Normally you should use radio buttons I guess, but my buttons have a special design.

thnx

Hi,

I have a setup with multiple driverless Webcams (Windows video class driver) and in Windows they are all recognised

by the same name: "USB Video device"

In IMAQ USB Init (= ImaqDirectShowDll.dll) the webcams are identified by their name and not their ID.

Because of this I can not switch between the webcams. Image always comes from the first connected webcam.

I proved it by installing a webcam with a driver and thus a differnt name in Windows. It worked OK.

Any one know how to fix this, so I can switch between the webcams by ID?

thnx

Take a look to "Login dialog.vi" in the Ni Example Finder (Help/Find Example...). This VI does exacly what you want.

Great thanks for your help! Now it works.

Hi ,

I realize that this is a very basic question, but I could not find the answer.

If I have a simple front panel control, like a Boolean switch or a selection list, how can I generate a Boolean TRUE event after a control change? (With this event I'd like to leave a loop) (STOP = TRUE)

thnx, Jasper

The Hytek Automation toolkit is pretty damn comrephensive for $399. If all you want to do is acquire and display, I agree that NI-IMAQ for USB Cameras is the way to go, or you might want to try Pete Perente's drivers - they're old and unsupported, but might do what you want with a bit of twiddling.

Thnx Crelf,

but I tried installing NI-IMAQ for USB Cameras and it keeps asking for NI Vision or the Vision Assitant that needs to be installed first.

So can't even install Ni-IMAQ for USB Cameras.

But maybe there is a way around this?

Thanx for the reply..

I found a link to this toolkit: http://www.hytekautomation.com/Products/IVision.html in this thread:

http://forums.lavag.org/Open-Source-altern...lkit-t1557.html

It 'only' costs $399 and the company claims NI Vision is not needed.

Now checking if there might be options with ActiveX that need no extra $ toolkit at all.

Hi,

does anyone of you know if it is possible to set up live webcam image aquisition

without the need for the expensive NI Vision addon? (maybe using activeX?)

(I am planning to buy the Labview Base system)

Thank you!
