TActiveX class using FHW64

[bradmaudlin]

Hello,

Has anyone used the TActiveX class using Harbour, FWH64 and MSVC 2015?
Do .ocx (ActiveX controls) files need to be 32bit or 64bit specific like .lib files?

The same code compiled using Harbour, FWH32 and BCC582 loads the ActiveX and works fine.
But when I compile using FWH64 it errors out on the ActiveX Statement.

MsgInfo("Start oNetePay ActiveX Control")
oNetePay := TActiveX():NEW(oMainDlg,"DSIEMVX.DsiEMVXCtrl.1",1,1,10,10)

I get to the MsgInfo() line then error out with this -

Brad,

I'm using harbour and msvc, 2015 for the purpose of this note but I still use 2013 as well. I use a 3rd party product named VideoReDo TV Suite which is a 32 bit app. I can create and use their object without issue from either a 32 or a 64 bit app. However I don't use the TActiveX() class, I use CreateObject()

oPlayer := CreateObject( "VideoReDo5.Application" )

I did just do a quick test with TActiveX() in the 64 bit app. It does not crash with the run time error you are seeing. It does behave differently than does CreateObject(), just doing a brief review of the TActiveX() source that appears to be more how TActiveX() is implemented and the assumptions my code makes and not a real problem. But it doesn't crash.

Brad,

I just tested FWH\samples\video.prg which I guess its similar to your code: the ActiveX is created from the dialog ON INIT clause

Here it is working fine in both 32 and 64 bits

To test it, please remember to copy fivewin.avi from c:\fwh\avis to c:\fwh\samples folder

Please use the most recent FWH 64 version 16.04
