It'd be better to use -1 instead of the strlen. Huw.

Bug in MoveFileEx
by Gerhard W. Gruber 01 Feb '02

01 Feb '02

I just played around with Thandor trying to install it and see what the differences are between Win98 and Wine because I noticed a slightly different behaviour. Now I discovered that MoveFileEx is not even available in Windows 98 but wine supplies it nevertheless. I suspect that the Setup doesn't check the windows version, but rather calls MoveFileEx and if that fails with not implemented returncode continues with other code to supply the functionality. I wrote a small test app to confirm this and this returns an error code when calling MoveFileEx on a native win98 whiel wine executes it. How shall I fix this? Shall I simply call GetVersion() to determine if MoveFileEx should be allowed or is there a different way with wine to determine which functions are available for which version (a global variable or such)? I looked through the sources but I couldn't find anywhere something where a versioncheck has been used to switch code but then again I don't know much functions where I know for sure that they are available in one version and not in the other. -- Bye, Gerhard If you think education is expensive, try ignorance.

CreateProcess API - undocumented use
by Ricardo 01 Feb '02

01 Feb '02

hi, I have a program that use the CreateProcess API with dwFileAttribute as a parameter. But not to use in the command line. It's used to write some data into a file and then another program read that file. But this isn't working. I'm not a programmer, I'm just testing the program. Does anybody know how can the program be changed, or wine patched, to solve this? thanks, Ricardo

Fix for MoveFileExA
by Gerhard W. Gruber 01 Feb '02

01 Feb '02

I just wrote a fix for a fixme located in MoveFileExA. Since this is the first time I'm writing something for wine I wanted to ask how I shall proceed now. Shall I simply add it into the CVS or does it have to go somewhere for revision? Also I don't want to submit it right now because my current fix is a bit ugly. The fix is applied for files that should be moved or deleted when windows boots after an application is installed. Currently there was a message telling the user that he has to delete/rename the specified files. Now I added some code that writes an entry in (WINECONFIG)/bootmove and (WINECONFIG)/bootdel when these functions are called. I also added some code in loader/main.c that checks if these files exists and if they do it will open them and deletes/renames the specified files. I hope this solution is acceptable. :) The only ugly thing about this is that the filenames for bootmove and bootdel are curerntly hardcoded where I need them. I don't know if there is a global space somewhere where I can add some fixed names so I did it this way for now, but this is not the best way in case the names should be changed or something and also I don't like hardecoded names. Another drawback of this approach is that it would be possible that more than one process is writing or reading at the same time there could be potential problems, so I'd like to hear some opinions if this is ok. -- Bye, Gerhard If you think education is expensive, try ignorance.

I looked at the GTK+ sources before creating that patch... for popup windows like menus and tooltips and stuff, GTK+ sets the override-redirect window attribute, which causes the window to become unmanaged.

ROTD (Rant Of The Day): patches
by Dimitrie O. Paun 31 Jan '02

31 Jan '02

Guys, I've come to _hate_ diffs attached as Application/OCTET-STREAM. Can you please, Please, PLEASE, attach them as Text/PLAIN? I use Pine over a ssh connection to read wine-{devel,patches}, and I can simply view the Text/PLAIN attachments, whereas I have to: -- press V to view the list of attachments -- select the attachment I want to view -- press S to save it to disk -- exit Pine -- start vi to actually view the thing -- restart pine... Just to view a Application/OCTET-STREAM attachment. Which means 2 things: -- I get frustrated (and look what happens when I do:)) -- I simply ignore those patches For all these reasons (and more), I think Linus is right when he insists on: -- ONE patch per email -- ONLY Text/PLAIN attachments. -- Dimi.
