Anyone actively working on ITypeInfo_fnInvoke and VariantChangeType?
before I start trying to get up to speed on it. Congratulations. My company's program now gets somewhere with the builtin ole dlls (thanks to fixes in the out-of-process COM) so I am interested in trying to get it to work completely with them (especially since the native ones no longer work) What I have just fallen over is some VB that calls a method that results in ITypeInfo_fnInvoke failed to convert param 0 to VT_VARIANT| VT_BYREF from VT_I2. So I changed the VB and ended up with ITypeInfo_fnInvoke failed to convert param 0 to VT_VARIANT| VT_BYREF from VT_VARIANT|VT_BYREF. Now it seems to me that it ought at least to handle the second case, but that probably demonstrates that I don't know what I am talking about. Anyway; if someone is already working on that sort of thing then there is probably little point in me trying to learn it all. However if no-one is then I guess I will start trying to learn it.

AFAICT I think that bug 4370 http://bugs.winehq.org/show_bug.cgi?id=4370 is relevant to this problem. If not sorry for the noise. -- Tony Lambregts

I had hoped others would continue development on typelib stuff, picking up from where I left off after the rewrite to use more of VariantChangeType, but unfortunately this isn't the case and I don't have enough time to work on this area too much. Fortunately, I don't think there are too many issues left to fix and already the new code in ITypeInfo::Invoke gets some programs working that wouldn't work with the old code. Does this patch fix both issues for you? -- Rob Shearman

Yes, thanks Rob. Are you going to submit it? (Now onto why it jumbs into the debugger in libkrb of all places!) -- Bill Medland mailto:billmedland(a)mercuryspeed.com http://webhome.idirect.com/~kbmed
