Hello

Active X controls are bitness specific.  When supporting dual bitness there are two entries in two different registry sections

Placing an ActiveX on a windows form is 32 bit specific.  When deploying as 64, connecting to the control will fail.

The only (partial) solution is OLEObject and CreateNewObject( ) - Then dynamic function calls and property setting may be possible.  It is NOT possible to write code to handle custom control events.  Dynamic coding is murky because nothing is exposed.

Does Appeon have plans to remove this limitation and allow form based dual bitness custom ole controls?

Thanks

Yakov

Oh dear Yakov. My main app uses a version of Roland Smith's embedded WebBrowser control sample (http://www.topwizprogramming.com/freecode_webbrowser.html) for a mail-merge document editor and display feature. If there's no way to force a 64-bit version, I don't see how that could work within an Appeon Web application, which has to work in both 32-bit and 64-bit browsers, do you?

And for that matter with the ExternalException event not supported in Appeon Web, I don't see how potential errors in embedded ActiveX controls or OLEObjects can be handled at all. (We use a number of OLEObjects as well for various features.) Am I missing something?

Mike S just pointed out to me in another thread that at least for the 32/64 bit OLE Control concern in Appeon Web apps, the solution is to use the IWA option (installable web app) to force the browser to be 32-bit. That doesn't resolve the problem for 64-bit PB apps, but I'm not yet clear when they would really be necessary.

I would post a bug report. Maybe they can figure out a way for the 64bit exe to automatically choose the 64bit version.
