calling labVIEW from windows thread fails

[Faisal M]

Hi,

I'm using LabVIEW activex from visual c++ 6.0. My aim is to run a vi and get the result from some control from vi. I successfully done this.

Since labVIEW application launching and running is a time consuming task, I moved the code to a thread. Now when i create the instance of the application it returns NULL

#import "LabVIEW.tlb"

 LabVIEW::_ApplicationPtr pLVApp;
 pLVApp.CreateInstance("LabVIEW.Application");

This code works when it is called from the main thread, but from a worker thread it fails.

Am i missing something?
