Dear Skegsy,

Fortunately, there is an example VI that does an excellent job of instructing one to use the custom control functionality to perform your desired action. To access these instructions, open LabVIEW, click [Help]>>[VI, Function, & How-To Help], search for "importing", select [graphics] under "importing", and click the link for "LabVIEW Custom Controls, Indicators, and Type Definitions". This link will open an Adobe Acrobat file with detailed instructions for your assistance.

I wrote (and attached) an example VI for you in which I customized one of the default LabVIEW boolean buttons to show an up arrow for the TRUE case and a down arrow for the FALSE case. I modified the Boolean button by right-clicking on the button from the Front Pa
nel, selecting [Advanced]>>[Customize...]. In the customize control window that now appears, you can modify any button using the help file instructions mentioned above.

Please note: the attached VIs may not function correctly in LabVIEW versions other than 7.0.

I hope this helps! Please don't hesitate to contact me if you need any further assistance. Have a great day!

Joe , thanks ,but you were correct , I only have the base V6 of labview ,The literature helped alot and it appears the custom control will do the job.

[Skegsy]

Can you guys tell me how I would use these two custom indicators , On three states , 1 is when the displacment is increasing the arrow blinks down, 2 is when the displacment is decreasing the arrow blinks upwards and 3 is when when nothing is happneng both arrows are visible or none at all .Thanks in advance .

[Skegsy]

I have included the vi in question , and there is an issue with detecting the state , wich I have written about , as in arrows blinking up or down as the displacment changes .I did recieve a nice example but coulndt work out how to manipuate this. Also my peak load indicator dosnt truly clear itself , it does temporarily but still displays a number when reset. Is there a better way to clear a indicators history.Any help with this would be great, or comments
