To launch the Type Properties dialog box, select Properties from the context menu on the root property or a subproperty of a custom data type you create.

The Type Properties dialog box contains the following tabs:

• General —Use this tab to change the value, numeric format, flags, comments, and attributes for the property. Click the Advanced button and select Flags from the drop-down list to launch the Edit Flags dialog box, in which you can modify the property flags, or select Attributes from the drop-down list to launch the Attributes dialog box, in which you can modify the property attributes. Typically, you need to configure property flags only when you develop a relatively sophisticated custom data type.
• Bounds —Use this tab to specify array sizes. This tab is visible only for array data types.
• Version —Use this tab to edit the version information for the data type, to determine whether the data type is modified , to specify how TestStand resolves data type conflicts , and to specify the earliest version of TestStand that can use the type when you save the file for an earlier version of TestStand.
• Cluster Passing —Use this tab to specify how TestStand passes instances of the data type as a cluster to LabVIEW code modules.
• C Struct Passing —Use this tab to specify how TestStand passes instances of the data type as a structure to functions and methods in C/C++ DLL code modules.
• .NET Struct Passing —Use this tab to define how TestStand passes instances of the data type as a struct to methods and properties in .NET assemblies.
• Python Parameter Passing —Use this tab to specify how TestStand maps the subproperties of a data type to the elements of a tuple parameter.
