LabStyle Meter control in CVI6

[svp]

If I pass a double value to SetCtrlVal() for a numeric slide Meter (lab-style) with Data Type double, it gives a run-time error saying "Invalid argument type: found 'double' expected 'int'"!!

I have never found this error in my projects.

In my experience, every time I have met strange behaviour like that you mentioned I was having control ID problems (I was really addressing a control different from which I intended to), so being in you I'd check carefully the value passed as panel handle and control ID to be sure to address the correct control.

Hope this helps

I agree with Roberto. If tracking down the control id proves problematic, I'd suggest the following:

GetCtrlAtttribute (panel, control, ATTT_CTRL_STYLE,&style);

That will tell if the control you're using is even a meter, or if it's something else.
