Under real DOS, "*" really means "*.". The user must type "*.*" to get all files. (This is the stuff that used to confuse DOS users converting to Linux - "*.*" no longer meant all files...) Also, your mailer seems to mangle your patches. You may want to attach them instead of pasting them to avoid that.

I did the exact same thing two days ago ('cept I put the TME stuff into windows/tme.c instead of adding it to input.c). Was part of making IE work as mentioned in my last mail regarding the stumbling block I hit with DPA that Aric has figured out.

16 bit menus
by lawson_whitney＠juno.com 17 Jan '02

17 Jan '02

Good day! Last time but one I tested juno 1.49 for regressions in 16 bit comms, it downloaded a new list of access numbers. Next it presented me with the attached menu (well, I attached a trace of it making the menu), which it expects me to work through and select a new number. Unfortunately, the menu seems to be either 0 or 1 pixels high and I can't find any of the controls in there. If somebody can tell me what parameter to what function provokes this, maybe I can work out a way to fix it. Of course, anybody who knows what [s]he is doing with menus is welcome to fix it, too. I have used this menu with this app, but not for perhaps a year. Lawson

[PATCH] Overlapped recv(), WSARecv()
by Martin Wilck 17 Jan '02

17 Jan '02

This patch needs testing yet - I am sending it for people to review and point out errors right from the start. Currently I only verified that it compiles. ChangeLog: implement overlapped recv(), much like overlapped IO in files/file.c. make WS2_32 WSARecvFrom() the "working" function, all others are wrappers only. implement WSAGetOverlappedResult(). NOTE: My patches submitted yesterday and today (16/01) to wine-patches are necessary for this one to work. CVS base version is 2002-01-15.

These CSIDL's are mapped to a unique value name in the registry. These functions are supposed to fail when called with a CSIDL which is not predefined. (Whats not saying wine knows all CSIDL's). > Has anyone else looked at this function, and does anyone have any comments or > suggestions on ways to address this? I'm thinking that these values probably > need to go into the registry, or something, rather than being stored in the > code... There is only a need to store the values in the registry when the path is different from the default value. If the there are no registry entrys in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\Shell Folders HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\User Shell Folders HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVer sion\Explorer\Sh ell Folders HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVer sion\Explorer\Us er Shell Folders the the default values are used. (Was in w95, nt4 like this. Don't know it its true for w2k since apparently most values are set at installation time and there are more values used than before.) Last but the not least: the current implementation was designed to work without much preset values in the registry to simplify the installation. The implementation should be cleaned up starting with ShGetFolderLocation since this is the common base of SHGetFolderLocation, SHGetFolderPath, SHGetSpecialFolderLocationand SHGetSpecialFolderPath and you should have a fallback to deal with a empty registry. (I'm not up to date with the wine installation procedure but the installer would have to put many keys in the registry for a good shell32 konfiguration.) Juergen --- juergen.schmied(a)debitel.net
