Hi Viktor <<< I've found it: You need to build it in MT mode (maybe you can put a screen message on this for ST build). So I did a new build, and on 64-bit, here's the GPF what happens in every ActiveX menu item:
--- Application Internal Error - Z:\demowvg.exe Called from WVG_STATUSBARCREATEPANEL(0) Called from WVGSTATUSBAR:ADDITEM(0) in .\wvgstatb.prg Called from WVGSTATUSBAR:CREATE(0) in .\wvgstatb.prg Called from EXECUTEACTIVEX(2382) in demowvg.prg Called from (b)EVAL(1430) --- >>>> So to be sure that all other components are working or not, except Statusbar control, attached is modified demowvg.prg. Please do the above test with it and click only first prompt of Active-X menu <Pure Xbase++>. <<<< Notice that xhb structure support isn't even MT safe, so I'd avoid it at all cost. I'd suggest to code manually a simpler structure (you can take Przemek code sent to the list of use the ones I've sent to you as an alternative solution), so you can see the issues, solve them and you can then reuse the method for other structure quite easily. I don't not how many structures you need to support on the .prg level, but maybe coding them one-by-one isn't something impossible. It would surely result in much better portable and quality code than xhb hack, which will need to be recoded in the future again and again. >>>> I tried Przemek's code. It works but it is not that elegant solution. May be he comes up with more sophisticated way as is employed in xhb. Till then... BTW I did not see any memory corruption if I use xhb implementation of structures. I am using it since ages. To be very sure I retested all my routines using xhb structures in MT environmrnt and I could not find even a single hb_out.log entry. But I may be wrong... <<<< The callback support also needs to be solved, you didn't address that part. >>>> I told before, it is extremely gray area for me. I just implemented Andy Wos code. He is better equipped to refine it. He is not available online these days, may be on vacations, otherwise I must have requested him.
