I gote a privet mail tipp for that Solution to, it lookt god untill I lookt at Technosoftwares "Software AG's EntireX DCOM on Linux" and AG's EntireX DCOM licens: http://www2.softwareag.com/Corporate/products/entirex/downloads/downl_exxdc… It seems like they wanted a license from all users (not just a development License), so that don't look good in our case. But they have a free vertion for non comersial use, if someone else is helpt by that... And a free trial vertion, for companies. Perhaps could be interesting to try it. Thanks for your tipp thow. /Rickard -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

Yes, but for me personly the Linux work in this company would probably be redused to a minimum. /Rickard -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

Other W->A crosscalls
by Vincent Béron 15 Sep '04

15 Sep '04

I played a bit with smatch and Wine (after reading http://people.redhat.com/mstefani/wine/smatch/), to try to get over what I mentionned in my last email (regarding winapi_check and cross-calls in parenthesis). I attach the smatch script to generate the results I have. It's still not perfect (the listview.c references are wrong, for example), but as it's tied to gcc it can detect some calls which otherwise would not be caught. For example, the calls to GetWindowLongA in header.c are in a macro. Not all of them are bugs: caution is needed when checking, although reducing the number of false positive would likely be welcome (either by modifying the script or patches). Vincent

winemaker

I was looking at the development tasklets for something I might be able to do. I noticed bug #230 - winemaker: Extract more information from the source files. How do I make known my interest in attempting to do this task?

Perhaps XP's advapi32.dll forwards these to cryptdll? --Juan _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

Perhaps XP's advapi32.dll >forwards these to cryptdll? It would make sense for this algorithme being in cryptdll instead and advapi32.dll just forwarding to it, if it really exports those symbols. MSDN talks about these functions being included as resource in cryptdll. Talk about being clear, to me they seem to be exported by name just as other functions. However W2K only contains the MD5 functions. A_SHA only seems to have gotten added to XP. Rolf Kalbermatter
