MapPoint Control 11 in Labview Container = Control could not be loaded

[brent2004]

I am working with Labview 6.1 to create an application using a "Microsoft MapPoint Control 11.0" ActiveX component. When I first create a container for it, I can insert the component and it will load and operate correctly. However, after closing the vi and reopening it, the container says "Control could not be loaded", and I need to re-insert the object to get it to work each time. I will need to compile and run this at some point, so I need to fix this problem or ditch Labview now. I have tried reinstalling Labview runtime and the MapPoint Application, but this does not fix the problem. Working with MapPoint as an automation object (without a container) seems to work ok, but I need interactive control through the container. Any suggestions?

I've never used MapPoint before, but in case it does not work properly with labview, then give the MapOCX from undertow software a try.

Thanks for the suggestion. I'd rather stick with MapPoint, but may end up needing an alternative. Do you know if MapOCX plays nice with Labview, v.6.1 in particular?

It worked fine for me when I used labview 6.1.

Hi,

Have you tried registering the ActiveX control(*.ocx) by using regsvr32 ?

Yup. Tried that one, as a search of the NI site comes up with reinstall and register as the only solutions for "control could not be loaded" errors ... but it didn't make a difference for me...

Odd to think that it can run fine right after the control is loaded, but after save/close/reopen, it's not working... hmmm.

try enabling the design mode after inserting the activex, right click on the control and check Advanced >> Design mode.
