IE5.x and Toolbars
by Guy L. Albertelli 24 Apr '02

24 Apr '02

This note is just to document what happens in IE5.5 when using the "Favorites" dropdown menu. With the native control, if the mouse hovers over a folder, IE will expand the folder. The expansion is accomplished by the following steps: 1. IE will set a timer on the Toolbar window with id=8001 2. WM_TIMER message for id=8001 on the Toolbar window occurs. 3. Since the Toolbar window is subclassed via comctl.410 (and friends), the subclass WndProc (in native comctl32) somehow calls a part of IE which issues a KillTimer and a PostMessage of message 0xc057 against the main window. 4. When message 0xc057 is dispatched, it issues a few TB_... messages and then eventually issues a CreateWindowExA for the next "BaseBar" window. This then drives the creation of the pop-out window. Since we don't support comctl32.410, .411, .412, and .413, this doesn't work (and will never work till we do support those undocumented routines). <rant> The reason MS can't make a modular Windows is because apparently no one there understands what modular means. Maybe they should work a summer building double wide trailers. </rant> Guy Albertelli <<galberte(a)neo.lrun.com>>

MoveFileExA bug and half-a-solution
by Jeremy Shaw 23 Apr '02

23 Apr '02

Hello, The Problem: There is a bug in MoveFileExA (files/file.c). MoveFileExA will (usually) call rename() in libc to move a file. Unfortunately, this causes problems because it does not update the sharing table. I will illustrate with an example. When the Office intaller tries to install Internet Explorer it sees that the file: C:\Windows\System\UrlMon.dll exists and moves it to: C:\Windows\System\IE4Setup\UrlMon.dll it then tries to create the file C:\Windows\System\UrlMon.dll but fails because of a "sharing violation". It believes that a file already exists at c:\window\systems\urlmon.dll, because, according to the shared table, one does. But on the disk, the file has been moved. The Half-a-fix: It seems odd to me that MoveFileExA is directly renaming the file. The other functions in the same file do their dirty work via wineserver. Does it seem reasonable that I should have to add a new wineserver request for "MoveFile" that will rename the file and update the share table? Or am I missing something obvious? Also of note: I do not think this has been a "problem" until some recent changes in MoveFileExA where these lines were removed: /* check, if we are allowed to delete the source */ hFile = CreateFileA(full_name1.long_name, 0, 0, NULL,OPEN_EXISTING,0,0); if(hFile == INVALID_HANDLE_VALUE) return FALSE; CloseHandle(hFile); If a file was being shared, this code would prevent it from being moved. So, perhaps that was the right fix? Maybe you can't move a file that is being "shared"? If that is the case, there does not seem to be code in place anymore to prevent you from moving a shared filed. Thanks for you help! I will send a patch in, as soon as I got one. Jeremy Shaw. Here is a trace of the bug in action: Its shows the file being moved, a log file being updated, and then the CreateFileA failing. ** 080baec8:Call kernel32.MoveFileA(403d1e94 "C:\\WINDOWS\\SYSTEM\\URLMON.DLL",40556734 "C:\\WINDOWS\\SYSTEM\\IE4Setup\\URLMON.DLL") ret=500f6a98 retval=00000001 ** trace:file:MoveFileA (C:\WINDOWS\SYSTEM\URLMON.DLL,C:\WINDOWS\SYSTEM\IE4Setup\URLMON.DLL) ** trace:file:MoveFileExA (C:\WINDOWS\SYSTEM\URLMON.DLL,C:\WINDOWS\SYSTEM\IE4Setup\URLMON.DLL,0002) ** 080baec8:Ret kernel32.MoveFileA() retval=00000001 ret=500f6a98 ** 080baec8:CALL mssetup.87: FLogOpen() ret=500f78ff retval=00000001 ** 080baec8:RET mssetup.87: FLogOpen() retval=00000001 ret=500f78ff ** 080baec8:Call kernel32.FormatMessageA(00000500,500f1be0,00000000,00000000,40556710,00000000,4055670c) ret=500f7927 retval=0000005a ** 080baec8:Ret kernel32.FormatMessageA() retval=0000005a ret=500f7927 ** 080baec8:CALL mssetup.100: FWriteToLogFile(403d20a8,00000000) ret=500f7938 retval=00000001 *** 080baec8:Call kernel32.SetErrorMode(00000001) ret=5009df3c retval=00000000 *** 080baec8:Ret kernel32.SetErrorMode() retval=00000000 ret=5009df3c *** 080baec8:Call kernel32.CreateFileA(4036a7e0 "C:\\WINDOWS\\IE Setup Log.Txt",c0000000,00000000,00000000,00000003,00000000,00000000) ret=5009df92 retval=0000008c *** trace:file:CreateFileA C:\WINDOWS\IE Setup Log.Txt GENERIC_READ GENERIC_WRITE OPEN_EXISTING *** 080baec8:Ret kernel32.CreateFileA() retval=0000008c ret=5009df92 *** 080baec8:Call kernel32.SetErrorMode(00000000) ret=5009dfdd retval=00000001 *** 080baec8:Ret kernel32.SetErrorMode() retval=00000001 ret=5009dfdd *** 080baec8:Call kernel32.SetFilePointer(0000008c,00000000,00000000,00000002) ret=5009e199 retval=0000356a *** trace:file:SetFilePointer handle 140 offset 0 high 0 origin 2 *** 080baec8:Ret kernel32.SetFilePointer() retval=0000356a ret=5009e199 *** 080baec8:Call kernel32.lstrlenA(403d20a8 "\tMoveFile succeeded: C:\\WINDOWS\\SYSTEM\\URLMON.DLL to C:\\WINDOWS\\SYSTEM\\IE4Setup\\"...) ret=5009e388 retval=0000005a *** 080baec8:Ret kernel32.lstrlenA() retval=0000005a ret=5009e388 *** 080baec8:Call kernel32.WriteFile(0000008c,403d20a8,0000005a,405566c8,00000000) ret=5009e161 retval=00000001 *** trace:file:WriteFile 140 0x403d20a8 90 0x405566c8 (nil) *** 080baec8:Ret kernel32.WriteFile() retval=00000001 ret=5009e161 *** 080baec8:Call kernel32.lstrlenA(500c68f4 "\r\n") ret=5009e388 retval=00000002 *** 080baec8:Ret kernel32.lstrlenA() retval=00000002 ret=5009e388 *** 080baec8:Call kernel32.WriteFile(0000008c,500c68f4,00000002,405566c8,00000000) ret=5009e161 retval=00000001 *** trace:file:WriteFile 140 0x500c68f4 2 0x405566c8 (nil) *** 080baec8:Ret kernel32.WriteFile() retval=00000001 ret=5009e161 *** 080baec8:Call kernel32.CloseHandle(0000008c) ret=5009e0ef retval=00000001 *** 080baec8:Ret kernel32.CloseHandle() retval=00000001 ret=5009e0ef ** 080baec8:RET mssetup.100: FWriteToLogFile() retval=00000001 ret=500f7938 ** 080baec8:Call kernel32.LocalFree(403d20a8) ret=500f7941 retval=00000000 ** 080baec8:Ret kernel32.LocalFree() retval=00000000 ret=500f7941 ** 080baec8:Call kernel32.CopyFileA(40556734 "C:\\WINDOWS\\SYSTEM\\IE4Setup\\URLMON.DLL",403d1e94 "C:\\WINDOWS\\SYSTEM\\URLMON.DLL",00000000) ret=500f6aca retval=00000000 ** trace:file:_lopen ('C:\WINDOWS\SYSTEM\IE4Setup\URLMON.DLL',0000) ** trace:file:CreateFileA C:\WINDOWS\SYSTEM\IE4Setup\URLMON.DLL GENERIC_READ FILE_SHARE_READ FILE_SHARE_WRITE OPEN_EXISTING ** trace:file:CreateFileA C:\WINDOWS\SYSTEM\URLMON.DLL GENERIC_WRITE FILE_SHARE_READ FILE_SHARE_WRITE CREATE_ALWAYS ** 080baec8:Ret kernel32.CopyFileA() retval=00000000 ret=500f6aca

The Euro symbol
by Medland, Bill 23 Apr '02

23 Apr '02

I am looking into getting the Euro symbol (Cp1252 0x80 ie U20ac) to display (and print) from Wine programs. I am running RedHat 7.1. From my quick literature search it looks to me like it isn't going to be easy. Am I being too pessimistic? Are there people out there who have been using it for ages? TIA Bill

internet explorer regression
by Michael Cardenas 23 Apr '02

23 Apr '02

I just picked up the latest cvs and some time in the last 3 weeks someone put in a patch that causes IE5 to crash when typing in an address in the address bar. I used office 2k pro to test. Also, windows media player can't install downloaded codecs, and it can in crossover office, but I'm not sure if that's a regression or an old bug. It complains about security settings. -- michael cardenas lead windows compatibility engineer lindows.com "Be the change you want to see in the world" -Mahatma Gandhi

Re: small patch for ./tools/wineinstall
by Speeddymon 23 Apr '02

23 Apr '02

alright thanks, the reason i thought you needed internet/cvs was because of the way that the winehq patch-making page was worded...it says to use cvs diff (instead of regular diff). I thoguht that there may be a difference in the 2, so I didnt want to make the diffs with diff when they required cvs diff. But now that I know, i will submit in diff format... Maybe the winehq site maintainer (alexandre?) could make that a little more clear (for us patch-contributing newbies/relative newbies) --- Tony Lambregts <tony_lambregts(a)telusplanet.net> wrote: > Speeddymon wrote: > > >as I have said a couple times, i dont have any way > to > >make the proper diff's due to the fact that I have > no > >internet at home, thanks again for making them for > me, > >I will be submitting the 2 diff's tomorrow (can't > do > >it here due to the fact that this computer is at > >compusa and has downloading disabled) > > > >Would there be anyone willing to make diff's for me > >when I have a patch to post? if so, could you > please > >email me directly so I know who to talk to? > > > >Thanks in advance > > > Well I would be glad to make diffs for you but it > really is not required > that you have CVS or the Internet to make propper > diffs. > > diff -u wineinstall.old wineinstall > > wineinstall.dif > > Where wineinstall.old is the original file (that you > saved somewhere or > got from the tarball) and wineinstall is the file > with your changes. > "man diff" will give you more information but thats > about all that you > need to know. > > You can edit the wineinstall.dif to get rid of the > .old extention but > I'm not sure its required.

toolbar.c problem (ATTN: Duane)
by Dusan Vujosevic 23 Apr '02

23 Apr '02

Hi, I am having a problem with the way toolbar.c was modified between revisions 1.107 & 1.108. My application (Signlab) pops flyout toolbars that stay around until they lose focus. The parent toolbar receives a 'TBN_DROPDOWN' message when someone clicks on one of its flyout buttons (button style: TBSTYLE_DROPDOWN). It creates a flyout at that point. With revision 1.108 of toolbar.c in Wine the parent toolbar also receives an WN_COMMAND after TBN_DROPDOWN message which causes Wine (rightly so) to send an WM_SETFOCUS (and WM_ACTIVATE). That causes the parent to regain focus and kills the flyout. The line that sends the WN_COMMAND is in toolbar.c at line 4540 (TOOLBAR_LButtonUp() function): SendMessageA (infoPtr->hwndNotify, WM_COMMAND, MAKEWPARAM(infoPtr->buttons[nHit].idCommand, 0), (LPARAM)hwnd); In revision 1.107 it used to be: if (bSendMessage) SendMessageA (infoPtr->hwndNotify, WM_COMMAND, MAKEWPARAM(btnPtr->idCommand, 0), (LPARAM)hwnd); And that worked fine because it would never send WM_COMMAND for a flyout button. Note that WinXP (that's where I tested) doesn't send WM_COMMAND after TBN_DROPDOWN has been handled. I would like to suggest revert that line back to 1.106 because it is the correct way. If other apps are were having problems with 1.106 (Duane was mentioning Acrobat Reader - I will test that..) I suggest that the problem might be elsewhere. Should I supply a patch? Cheers, Dusan
