Selector for every case

[JPKelly662]

Hi,

I've created a case structure where I have a 32-bit integer (coming from an index array) as the selector values.  The selector values range from 0 to 1720.  The input tunnel is a 2-D array of single 32 bit numbers.  I'm performing a simple multiplication by a constant on the 2-D array, inside the structure, and then sending it on its way to the output tunnel of the structure. 

I've created several cases and set a default case as well for any selector value that doesn't fall within my specified cases.  I keep getting this error now: Every case in a Case structure must have at least one selector value that selects it.  Firstly, I really can't have a case and just have it not be selected if it's selector value doesn't come up?  Secondly, in the "set" of 32-bit integer selector values that come through, all of the cases are covered!  So, I'm not sure why this error is coming up. Am I missing something?

Thanks

Does your default case actually implement "Default" or did you simply handle every other value from 0 - 1720 that is not explictly handled in another case? The case structure MUST handle every possible value possible from the 32-bit interger. The easiest way to do this is to add an additional case and right click the case structure and choose "Make this the default case".

I actually made an extra case, right clicked, and chose "Make this the default case".

could you post the code?

[JPKelly662]

I can try.  It's a small section of a much larger, very complex code.  What is the easiest way to post the code?

Just create a simple copy of the VI you are having troubles with and post that.

[Charles_CLA]

Attach the VI directly

[JPKelly662]

Unfortunately, I don't think I'm allowed, by my company, to post the entire VI. I will ask.  In the meantime, I've attached the case structure.

You need a bit more than that. You should at least leave the control that is wired to the selector. A borken wire is pretty useless to see what is going on. However, it is complaining about the empty cases.

There were a couple of cases in the structure that didn't have any way to handle them. That is what is causing your problems, you cannot have a case in a case struct that doesn't have a value assigned to it. This code cannot be accessed and LabVIEW won't allow that.
