How to get Numeric Type of a member in Type Palettes' *.ini file

[MichaelNguyen]

In Type Palettes, I tried to get a member type from a type in a *.ini file, the member numeric type is Signed 32 bit integer (as indicated in Properties, C Struct Passing), but when I used Common C Adapter, methods GetStructMemberType(), it returns StructMemberType_Float64. Is this method has a bug, or do I have to use different method to get member numeric type?

Thank you so much for the help.

"numeric type is Signed 32 bit integer (as indicated in Properties, C Struct Passing)" - I quess these are properties from "Memory Layout for Property" section, of the Type Properties -> C Struct Passing. So this is just about how number will be processed/held in memory while struct passing, but not its representation in TestStand iteself. So that function GetStructMemberType() returns everything correct - b/c if you'll check representation of number in type properties (right-click - Representation...) you'll see there just 64-bit formats.

Hope, this will help.

So is there any way that allow me to extract the Numeric Type in C Struct Passing, "Memory Layout for Property"?

Thanks

I could get it by doing this:

RunState.Engine.GetAdapterByKeyName(FlexCAdapterKeyName).AsCommonCAdapter.GetStructMemberType(RunState.Engine.GetTypeDefinition("Name Of Type"), "Lookup String")

For example if I had a type call Foo which was a container with a numeric in it called MyNumber then my function would look like:

RunState.Engine.GetAdapterByKeyName(FlexCAdapterKeyName).AsCommonCAdapter.GetStructMemberType(RunState.Engine.GetTypeDefinition("Foo"), "MyNumber")

This will return the numeric value which represents the enumeration found in the help here:

So for instance Float32 will return a 0.

Hope this helps,

This maybe is a dumb question, but how do I start RunState?

[~jiggawax~]

You have to have an execution.  How are you calling the type?  Is this done in TestStand or another language?

I'm attaching a small example that demonstrates this.  Let me know if this helps.

This is done in C#, and my program parse the existing sequence file. Basically, this is how I do it, starting with:

_appMgr.LoginOnStart = false;
_appMgr.Start();
_engine = _appMgr.GetEngine();

_dllAdapter = _engine.GetAdapterByKeyName(TS.AdapterKeyNames.FlexCAdapterKeyName) as TSAdp.DllAdapter;
_commonAdapter = _dllAdapter.AsCommonCAdapter();
TSAdp.StructMemberTypes elementType = _commonAdapter.GetStructMemberType(typeDefStructProObj, elementName);

The above elementType always return StructMemberType_Float64, but it is actually 32 bit integer.

I don't have a C# compiler on my machine.  I tried what you are talking about in LabVIEW only and it works flawlessly.  hmmm?

What  version of TestStand are you using?  I tested mine in 2010.

[MichaelNguyen]

NI TestStand 2010. I am new and I don't know why. Thanks for your help
