Programatically Creating LabView Step in TestStand Problems

[SercoSteve]

I am writing a LabView App that generates TestStand Sequences.

When programatically 'specifying the module' of a TestStand Step calling a LabView VI, is it possible to set the values of the parameters passed to the VI by Name?  I am currently creating steps fine, but the only way I can set parameter values is by using the parameters index. 

It would be really nice if I could reference the parameters by the name specified in the VI rather than the index derived when the VI is created.

Any ideas?

How are you setting the parameters?  If you are using the TestStand Adapter API, you can iterate through the LabVIEWParameters parameter of the module, and look at the ParameterName property.

Thanks for reply Allen

I have moved things on since I posted my message.  I am iteratively using the parameterName property to create an array of VI parameter names, that I then search, by parameter name passed in, to get an index to that parameter that can then be set by ValueExpr.

When I wrote my message I guess I was hoping there would be a 'get property index by name' method for parameters, but hey the way I have done it works fine.

Thanks Again

Hello,

I am doing something similar. I am trying to programmaticaly insert a sequence call into a sequence using Labview and then specify the module properties. I was able to create the sequence call, but I am stuck at the Specifying the Module options. I found a method called "Specify", but it causes a popup to occur asking the user to manually specify the module properties. I want to be able to do this step silently without a popup. 

Thanks,

Sam

Hi Sam

Yep it gave me some problems as well.

See attached.  .JPGs' not Snippets I am affraid my version of LabVIEW doesn't support them.

This is exactly what I have been trying to do. Can you please add the source code ? I need to see how it is done in the Specify Module VI.

Thanks,

Sam

Hello Steve,

Sorry to bother you again, but the VIs are missing all the SubVis. These are the actual VIs I was interested in.

Thanks,

Sam

Sorry Sam my fault

Hopefully these are all of the SubVIs and SubSubVis
