I know how to check with array with variables but i am not sure how to check for array with strings......

Pls let me know.

thanks

Are you looking to see if an array of strings is empty?  getnumelements(array name) == 0

Are you looking to see if an array of strings has an empty string in it?  Use a FOR loop to go through each element and perform a check with an empty string ("").

I have declared the array with string and I need to check whether this array has any strings present or not......

I'm still not following you.

Ok, you have an array of strings.  Is the array declared as a certain size or start off empty?  Are you adding and removing elements from the array?  Can you show some code to demonstrate your setup?

size of Array of string is declared as a empty under parameter......in future i may add strings to that array and i need to check whether array is empty or not before procedding with other conditions.......

Ex:

parameters.string Arr[]

if (parameters.string arr[] == empty)

    failed

else

    a= name 1 = name 2

So i need to check string arr[] is empty or not

if (parameters.string arr[] is not empty)

   b= name2 + name 3

else

    a= name 1 = name 2

pls let me know

thanks,

Use the GetNumElements function:

locals.empty = (getnumelements(parameters.array) == 0)

Mandya,

Crossrulz already gave you the solution in his first post.  You need to use the GetNumElements function in an expression.  This function takes an array as its parameter and returns the number of elements in the array.

So GetNumElements(Parameters.MyArray) == 0

From the TestStand help:

Number GetNumElements(Array array)
This function returns the number elements in an array.
Parameter 1: A single dimensional array.
Returns:     The number of array elements.

Cheers,

It looks like you are still looking at an array.  It is just inside of a container.  Should have no problems.
