Unable to view properties of Amplitude and Level Measurements

[jdai]

I'm new to LabVIEW and just installed ver 8.6 on my machine. When I open the TutorialGenAnalyzeDisp1.vi, the Run button is disabled. When I double click the Amplitude and Level Measurements I get a dialog box says "Unable to view properites". If I click the Run button, I get an error message: "Block Diagram Errors /  SubVI 'Amplitude and Level Measurements': SubVI is not executable."  

I have LabVIEW base development system. Is that possible that I don't have that item in my library or some installation problem? I hate to re-install LabVIEW. It took more than 3 hours to install.

Hi jdai

The Amplitude and Level Measurements Express VI is included in LabVIEW Full and Professional Development Systems, not in Base. So, just like you thought, you lack some of the components necessary to run this VI.

Thanks David. What I'm trying to do is to write a LabVIEW custom control which is actually a wrapper around an OCX (ActiveX) I wrote. Is that possible with the BASE version?

Hi jdai

You should be able to use OCX files in VIs with LV Base. You'll need to registert the OCX file in on the system (regsvr32 in Windows), then insert it as an ActiveX object (Controls Palette->.NET & ActiveX->ActiveX Container, place it on the frontpanel, right-click and select "Insert ActiveX Object") and then use Propery and Invoke Nodes to access the properties and methods. Hope that helps.
