array not updating in a subvi

[Mathan]

Dear champions,

When user selects a particular input, the array will output 10 values and for another input, it will output 7 values.

The problem is that, on repetitive calling, when selecting second input, array has 7 values + last 3 values outputted by the first call.

How to handle this? I used local variables, but no use.

Thanks & Regards,

Mathan

Hi mathan,

why do you use local variables? Can you show your code, i don´t fully understand the problem?

Dear mike,

I can't able to post that code here. Please understand. I will explain bit more in detail.

Actually, the user will select either 1 or 2. If he selects 1, then there will be some output (10 values) in an array. If he selects 2, then there will be some 7 values outputted in the same array.

On continuous calling of this vi in another vi, when the user selects 2, the array holds first 7 values correct, but the last 3 values remains showed (occured during selection of 1) and not cleared.

But in the same vi, it works great. That is for selection of 1, it holds 10 values and selection of 2 will shows 7 values.

Give me a workaround. I tried with initialize array clearing the array at the time of each call. But nope....

Hi mathan,

did you store your data in a shift register? You can use the array subset function. See this picture.

Hope it helps. Mike

Dear mike,

I am sorry if i was not clear. Still finding difficulties.

In the subvi, i will get these array values case 1: 3B 6D 01 7E 6F 01 80 AB 90 00 and also the length of this array(Here 10). case 2: 3B 6D AB 90 00(Here 7). Both outputs(array and length) are coming from a dll output.

When i called the subvi in another vi, and just displayed the array (using connector panes), the array was not properly displayed as i told in previous posts.

Now i just want, if i have array length and array from a subvi, inside the main vi how to limit the array display with that particular length.

The problem solved. Just used Reshape array function. That did the trick....

Hi Mathan,

IMHO "Array Subset" seems the more logical answer here...

Dear GerdW,

Yes. Just now checked that option also.  Works very fine. 

Thanks,
