Hi,

32bit OCX can only be used by 32bit applications.

If your operating system is based on 64bit then your AutoCAD and so VBA is running on 64bit.
You'll have to replace that controls by other ones supported on 64bit .

Hi @Alfred.NESWADBA

you wrote "32bit OCX can only be used by 32bit applications."

but while trying to answer to >>this post<<  I happend to meet >>This SO post<< which seem to say the opposite!

actually I succeeded at running "comdlg32.dll" in my full 64 environment (W7 SP1 64 bit & Autocad 2014)

am I correctly addressing the issue?

comdlg32.ocx and comdlg32.dll are not the same thing: the latter is Windows API. As the link you rfrerred to, it can be used in 64-bit process with proper P/Invok; while the former is the ActiveX UI wrapper to comdlg.dll, which is 32-bit, thus cannot be used in 64-bit VBA (since Acad2014).
