Using Combo box to create options

[Rami_Y]

Hello,
I am using a Framegrabber to acquire my images from our custom made sensors. We have several models so I wrote several Drivers for each one. I have managed to use a combo box with the names of the sensors to select which driver is loaded into the IMAQ board. However, because the application is getting more and more complex, and because I want to have one universal application for all our sensors, I want to have the ability to select different options according to the driver that is selected. For example, if I select Sensor A, and I want to use the serial communication, I want the address of sensor A to be used in the VI. If I choose Sensor B, the values related to sensor B are to be chosen. I guess the idea is simple to implement using an If Statement in C or other languages, but I don't want to go through that mess, and I want to implement it with LabVIEW.

I could use a Case structure, but that only gives me two options. And I am not very good with Event structures and I do not know if I can use it for this. I also tried to use a local variable, but it would not let me change the values associated with the labels.

If you understood what I was trying to say, and have an idea, I would greatly appreciate your help. If you are interested in helping but need a visual illustration, I can put a quick VI together for you.

Thank you in advance,
Rami

Wrong ! 😉
The case structure can handle multiple cases : just wire your combo box to the case input !
That's one of the greatest LV functionnalities...

Hello CC

You are absolutely correct. This is as good as a traditional If Statement.
Thank you very much, I am sure this small tip will open a lot of doors for me. Hahaha.
Thanks again

Hi.

I think I am doing something wrong, but, maybe someone can quickly enlighten me.

The situation is this.

I have a combo box with about 65 values. I want to feed these into a case structure (to select a range of settings to use later on)

How do I get the values to also appear in the case headers? All I have is true and false..

My output of the combo box is a string, not  a number. is that why I dont get the values automatically?

I've attached the combobox and a case structure.

If you want 'text' to automatically show up in the selector of a case statement, use an enum instead of a combo box.

Ok, so that is what I am doing wrong...

Thanks.
