Calling an ActiveX Object from LabView

[GWolford]

I have an ActiveX method that returns an object as a variant. The object has methods that can be called.

The following is functional vbscript code that I want to code into LabView.

Set Analyzer = WScript.CreateObject("CATC.USBTracer")
Set Trace1 = Analyzer.OpenFile("data_0_Sample.usb")
Trace1.Save "S:\data\test1.usb"
Trace1.Close

The first line is implemented in LabView as an Automation Open

The second line is implemented in LabView as an Invoke Node with OpenFile as the method

How do I use the variant to call the Save method from the returned object?

You want to use the Variant to Data node, wiring in an ActiveX constant configured to the interface type you want.
