OLEPictureImpl_SaveAsFile

[Ross Clement]

Hi. I have an application (Halosim3) that I would like to have working
under wine. The application works reasonably well, but is unable to save
pictures to disk. With a bit of tracking, I've discovered that it calls
OLEPictureImpl_SaveAsFile to save the image that it generates. This
function (in dlls/oleaut32/olepicture.c) is a "stub" only, and writes
back This->datalen bytes of This->data. Looking at the code further, it
seems that This->data is only initialised when an image is loaded from
disk. Hence any image editing or creating program that creates an image
in memory, or modifies an image after it is loaded, won't work. 

I would like to ask if anyone is working on OLEPictureImpl_SaveAsFile,
or planning to. Otherwise I may have a hack at it myself.

I'm not subscribed to the winehq mailing list, but will check the
archives sometime in the future. If anyone wants to contact me quicker
than that, please cc it to my email address as per this email.

Cheers,

Ross-c

Yes, our support for the visual basic APIs (basically a lot of OLE
is really VB runtime code and not used by much else) is not great.

Go for it. Feel free to ask here or on #winehackers (freenode) if you get
stuck. If you do decide to have a go, I'd suggest doing what I do
and subscribing to the list then switching mail delivery off. You can then
use gmane to see and post to the list using a more convenient interface.
