Determine the Size of Each Dimension of a 2D Array in TestStand

[awdeorio]

How do I determine the size of each dimension of a 2D array in TestStand?  myArray.GetNumElements() returns to TOTAL number of elements in the (2D) array and doesn't help me.  I need to iterate over only one dimension.

Thank you,

Andrew

Look at GetDimensions, GetDimensionsSizes, GetUpperBounds, and GetLowerBounds and decide which suit your case best.

GetUpperBounds(int dimension) is exactly what I need.  Unfortunately, it doesn't seem to be present:

Error in call to TestStand API member 'PropertyObject.GetUpperBounds'.
Method 'GetUpperBounds' does not exist in interface 'PropertyObject'.

This is the result of code:  Locals.my2Darray.GetUpperBounds(0)

P.S.  I am using TestStand 4.2

Try Locals.My2dArray.Type.ArrayDimensions.GetUpperBounds()

[StevieZ · Accepted solution]

GetUpperBounds exists but just not in that context. Try something like the following...

Locals.MyDimensions = Locals.MyArray.Type.ArrayDimensions.GetUpperBounds ()

Where Locals.MyArray is your 2-d array that you want the dimensions of and Locals.MyDimensions is a 1-d array to store the dimensions. Something like...

Locals.MyArray.Type.ArrayDimensions.GetUpperBounds()[0]

... would work as well, this example would return the number of elements in the first dimension of Locals.MyArray.
