Hello

How to embed ActiveX controls on a window that will be deployed in both both 32 and 64 bit

The painter is 32 bit.  It access the 32 bit Registry section. For OLE objects it displays a list of 32 bit controls for insertion on a form.  It then hard codes the 32 bit binary information at the end of the source in something like this

This bit specific encoding renders the form useless for 64 bit deployment. 

How can 64 applications gain runtime access to a  visual OLE control ?

Thanks

Thanks for your response,

This is a .NET MSIL assembly whose classes are invoked via COM InterOp from the GAC,

COM interop has a KEY 

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\

{2D569ACA-A861-4033-BEEA-2123845E1AE4}

Inproc server C:\Windows\system32\mscoree.dll 

Assembly Name  

Class Name

and entries in both 32 & 64 bit COM areas under that key which

64 bit entry points to master entry

32 bit has its own values 

Inproc server C:\Windows\system32\mscoree.dll 

Assembly Name  

Class Name

 

Will this not work with PB 64 bit to .NET visual assemblies?

Comment
I have been tracing this down to find a root cause. Seems like OLE visual control is a .NET WinForm connected to PowerBuilder using the MS Interop Forms Toolkit 2.1 - There are a couple of unusual factors



1) Component Events are NOT integrated into the PB Script Editor when the OLE control is placed on the form



2) I have to declare the component defined events as PB custom user events on a container UserObject which hosts the OLE WinForm. If these events are not declared, the visual control throws runtime exceptions



3) The events are properly invoked in a 32 bit application. But they are NOT invoked in 64 bit application

This is the problem



Question: Is the problem with the InterOp toolkit - where it might not have 64 compatibility, OR is it something on the PB 64 bit implementation where something is not properly exposed?



Anyone with experience in MS Forms InterOp?

Are both versions of the control compiled with the same GUID? Are both versions of the control registered at the same time, one in C:\Windows\Syswow64 (32bit), and the other in C:\Windows\System32 (64bit)? Are both OCX files named the same?

At runtime, under 32 or 64bit apps, Windows will read the registry and attempt to load the OCX based on the GUID as requested from the program loading it. If the 32 & 64bit versions differ in ID, it won't be able to find the correct one based on a single GUID.

Yes sir. Controls in both bitnesses are installed

Yes Sir.  These are home grown components that successfully integrate in the 32 bit deployment world.

Hi Yakov;

  Is the ActiveX control in question available in both 32 & 64 bit?
