LabVIEW ActiveX Server errors when passing parameters from Matlab

[wdebruyn]

I'm calling a LabVIEW (LV) vi from Matlab using LV as an activeX
server. I perform the following call without parameters and everything
works fine.

invoke(vi,'Call');

However, when passing an array of double I get the following error:

d=zeros(1,4096);
invoke(vi,'Call',d);
??? LabVIEW : paramNames type mismatch. Expected 1D array of
strings or 1D array of string variants.

I've tried several different types of numeric parameter without
success. Anyone have any ideas on how to pursue this problem...

Check out the following example. This example VB client talking to LV as ActiveX Server. You might figure out what you are doing wrong.

Make sure that you pass values to LV controls using the "SetControlValue" method and not as argument of invoke!

Hope this would help U
