VBA load MS Control on Windows 64 bits

[diegoal]

Hello,

I am not able to use a MS control on my AutoCad 2015 64 bits (mscmoctl.ocx). I already registered the OCX control and loaded it in VBA / references 

In the other side, for instance, I am able to use it on Excel (see picture).

What should I do to add an OCX control to AutoCad VBA Ide?

Thanks,

You did not say, but judging from the picture you attached, your Excel (or your MS Office suite) is 32bit, while your VBA in AutoCAD 2015 is 64 bit.

You cannot use 32 bit ActiveX control in 64-bit process. You can tell from the piture you attached by the different items available in Excel and Acad2015's "add components" dialog box: there are much less items available in Acad 2015's 64bit VBA, only 64-bit controls are listed.

At this stage of ActiveX components, in terms of the technology's age, I would not expect there will be more 64-bit components available, which makes using AutoCAD's 64-bit VBA for a advanced development very difficult.

If you have to use the 32-bit controls, you either going bacl to AutoCAD 2013 or earlier: while you can still enjoy 64-bit AutoCAD itself, its VBA is 32 bit (thus runs very slow and with possible other issues); or you simply use 32-bit AutoCAD (still available for latest AutoCAD, 2015).

Hello Norman,

I was postponing my VBA - Vb.Net code conversions but now, according your reply, I don't have alternatives 😕

Thanks for your reply.
