Propert Loader "PropertyList" description required

[Rupert Hewitt]

Im looking for a description of the fields in the property loader step.propertiesList :-

step.propertiesList[0].PropertName (Variable to be loaded)
step.propertiesList[0].PropertyType (1 ???)
step.propertiesList[0].DataType (1 - string, 3 - number ???)
step.propertiesList[0].ColumnName ( ??? is this required ??? )
step.propertiesList[0].IsArray ( True for array False none array ?)

Im looking to write a custom step which will at run time change the property list, basically loading of arrays is painful to enter or very slow ( I have tried using the Pre-Expression method to allocate arrays and this adds approx 600ms overhead due to reloading the csv - xls file ), I rekon I should be able to dynamically size and allocat
e values to the Properties list if I know what the required formats are.
With my custom step I can then specify the Array and number of elements and it should create the required number of elements for me.

Hi Rupert,

Looking at the source file used for the property loader step type, here is what each of these mean:

PropertyName: Variable/Property to be loaded
PropertyType: The location of the property to load. This is an enumerated value with the following values (from TSDBCommon.h):

PropertyType_Step = 0,
PropertyType_Local = 1,
PropertyType_FileGlobal = 2,
PropertyType_StationGlobal = 3,
PropertyType_Other = 4

DataType: The datatype of the value to be loaded. This is an enumerated value with the corresponding values (from tsapicvi.h):

TS_PropValType_Container = 0,
TS_PropValType_String = 1,
TS_PropValType_Boolean = 2,
TS_PropValType_Number = 3,
TS_PropValType_NamedType = 4,
TS_PropValType_Refe
rence = 5

ColumnName: This is required in order to specify column to step property mapping. TestStand uses this to determine the column in the file in which the property is located.

IsArray: True if the value is an array (i.e. Locals.MyArray[x]), false otherwise.

Hope this helps!

Excellent ! thanks very much.

The Column name appears to contain some wierd mangled version of my origional "Property name"
ie
PropertyName[1] = "TxNvramAddr.functionName[0]"
ColumnName [1] = "TxNvramAddr_functionName0_S"

Does this only get used if you are loading "Step Properties", and not variables ?

Hi,

Please have a look at the file \Components\NI\StepTypes\Database\PropertyLoader.c. In this file you will see a function called "BuildColumnName". Have a look at this function, this is where the ColumnName value is created.
