There is an option in the VI properties dialog to hide the toolbar while the VI is running.

File >> VI Properties... >> Window Appearance (category pull-down) >> Customize (button) >> Show Toolbar When Running (checkbox)

oh man..this is actually wat i want!!

thnx ya.. :thumbup:

Yes, buy a DAQ card and install it in your computer ;-). Otherwise no, the parallel port is a digital interface with signals when going above 2.4 V meaning logic high and below 0.8V meaning logic low. There is no analog measurement built into the parallel port nor any other part in a normal PC. (This leaves out the temperature and CPU voltage level controls nowadays built into the power management of modern PCs but you couldn't use them for measuring arbitrary port signals anyhow).

hmm...its quite hard for me to get the DAQ card becuz of my current location...

or is it possible to directly show all the voltages difference in parallel port, not measure it?

i got 1 VI that is get the power status of the pc, i want to get something like this which is related to parallel port ...i found out that this VI is using the Call Library Function

How to hide the toolbar when then vi is running?

is it possible to do so ?

sorry if i ask a dumb question...but i would like to know wat is this Call Library Function?

got how many function that the user can call ??

sorry..is there any function that able to measure the output voltage of the parallel port, on the inside Labview?because i need to measure the output voltage by juz only using the indicator as the voltage display

Download OpenG Commander and install the PortIO package (oglib_portio). This will allow you to write to the parallel port.

sorry, after installed the commander software, it pops up this error window...i dont know wats the problem....

guys..recently im deal with my project that is related to using labview to control the ON/OFF of the LED by parallel port, but im totally no idea about how to create the VI about this...

sorry for my poor English..

What kind of a security system are we talking about here? A building security system? an airport security system? a prison??

Please provide as many details as you can... without breaching the secuirty

oh..sorry...

the system is for home security...

is there any feature that still can add in without add in any device? (ex. webcam)

becuz now the system already included features like Voice recognition system, Iris detection, Image identify and moving object detection, i wonder still can add in any feature tat is related to this home security system...

as the title, is there any special function tat can use labview to implement?

of course tat muz using labview/imaq vision..
