Explorer in XP and Wallpaper changing...

[Alex Ionescu]

Hi everyone,

Firstly, it seems our explorer doesn't load in WXP anymore. Looks like 
we are directly importing NtGdiBitBlt (undocumented function) instead of 
relying on BitBlt. I don't see any need to use undocumented native API 
in explorer... I've also heard that it's impossible to built it with 
msvc because of numerous (43) template errors. Bizzeh on IRC knows more 
about this.

Secondly, I've tried out the new wallpaper changing, and it crashes on 
my build, inside win32k. I am running qemu + optimized build...can 
anyone else repro? I will try other BMPs to make sure mine isn't 
corrupted (which still means there' s a bug).

Best regards,
Alex Ionescu

It works on real hardware, but depends on the size too. If 800 x 600 or better
(1024 x 1024, 1024 x 768) I can change the background, but less than that it
does not stick. Oh, it does not modify the registry, so after a reboot, I get
the same original background.

With winfile.exe;

(objects/gdiobj.c:803) Attempted to lock object 0x0 that is deleted!
(objects/bitmaps.c:71) Invalid source dc handle (0x00000000) passed to NtGdiBitB
lt

Palbitblt;

(objects/gdiobj.c:603) Attempted to free global gdi handle 0x605025f, caller nee
ds to get ownership first!!!

FYI, I can install OOo_114_Win32 with some gui problems but it did trash my
registry entries and made Foo.lnk to everything. So I reinstalled registries.

OpenOffice 1.1.4 and WinQuake;

GDI32: CreateDIBPatternBrush is unimplemented, please try again later.

OpenOffice 1.1.4 after exit, it's still there;

(objects/gdiobj.c:845) Attempted to lock foreign handle: 0x80402f0, Owner: 0x214
  locked: 0x0 Caller: 0x100, stockobj: 0x0

Taskmgr; Hay it work now, Performance page looks like it needs some fixing up
(win32k.sys, maybe?)! After exit Taskmger get this,

(ntuser/message.c:1135) Attempted to post message to window 0x19c that is being
destroyed!

I used pskill to kill it off, or you can use a new taskmgr window to kill the
one you exit from.

Thanks,
James

The linker appears to be screwed. I just tried it myself and it neither 
imports NtGdi* functions nor is broken on windows (xp).

I don't have problems compiling explorer with MSVC.
Make sure you use at least VC++ SP5. Without service packs the
compiler is quite unusable for compiling C++ template code.
