ActiveX control can not be loaded after reload the vi

[inhaler]

Hi,

I'm using the MS treeview control to display some folder structure, but when I close the labview, and restart it, the control can not be loaded. The exact message is "control could not be loaded!". Even the example in Labview 6.1 -- FamilyTree has the same problem.

I'm wondering how to solve this problem.

Thanks a lot.

Hi inhaler,

I recomend contacting Ni support at 1 (800) 433-3488.

If the shipped example does not work, they will be interested.

I have also heard of an on-confirmed rumor that there are issues with using the MS treeview in LV.

I just solved the problem by register the ocx, but I'm still confused because this ocx came from MS, supposed to be registered by default.

Hi,

The only issues I know of with the Treeview example, are memory leaks. This
means, that while running the example, the memory slowly fills.

Regards,

Wiebe.

Hi,

It's not registered by default. It's registered if one of MS's applications
registered it. It doesn't even need to be shipped with windows, although it
is for most installations. I've used labtops that where shipped with a
'minimum' installation, that didn't have the ocx installed.

Regards,

Wiebe.
