I can’t get id with EdmCmdNode_ParentDocIDs in IEdmCmdNode interface

IEdmCmdNode cmdNode = (IEdmCmdNode)cmdData.mpoExtra;
int childdocid = (int)cmdNode.GetProperty(EdmCmdNodeProp.EdmCmdNode_ParentDocIDs);

The Error Code is below.

Message "Method returned a COM Variant type that is not Interoperable."
System.StubHelpers.ObjectMarshaler.ConvertToManaged(IntPtr pSrcVariant)

I have actually not used that before. I would probably use let the compiler infer the type.

var childdocid = cmdNode.GetProperty(EdmCmdNodeProp.EdmCmdNode_ParentDocIDs);

Check if your pdm dlls embed interop types (from the reference properties) are set to false.

Might worthwhile to report this to apisupport@solidworks.com

That’s a shame :frowning: 11 years and still a bug
