MakeProcInstance: must use CURRENT_DS if hInst == NULL.
* [misc/shell.c]
SHELL_GetResourceTable, InternalExtractIcon: fixed broken .ICO handling
* [windows/winpos.c]
DeferWindowPos: removed "same parent" requirement.
Which doc states that this is required ?
Sat May 16 20:08:11 1998 Alexandre Julliard <julliard@lrc.epfl.ch>
* [loader/module.c] [loader/ne/module.c]
More NE module cleanups.

* [relay32/wnaspi32.spec]
New file.
* [misc/lzexpand.c]
LZCopy auto-decompresses LZ compressed files, even if they are not
specially flagged. Fixes some InstallShield problems.
* [misc/registry.c]
Some fixes for RegQueryInfoKey (reference program monkey.exe
from Win32 SDK works now better). Probably still has faults.
Fri May 15 08:58:58 1998 Martin Boehme <boehme@informatik.mu-luebeck.de>
* [graphics/mapping.c] [include/dc.h] [include/gdi.h] [objects/dc.c]
Reworked the way world transformations and mapping modes are handled
so that both of these transformations can be computed in a single
step.
* [graphics/painting.c] [graphics/path.c] [include/path.h]
More GDI path support.
* [graphics/x11drv/graphics.c]

InitCommonControls calls ImageCommonControlsEx.
Registering code of the common controls had to be changed
(see XXXX_Register functions).

Added hypot,j0,j1,jn and ceil.
Wed May 13 19:10:10 1998 Pascal Cuoq <pcuoq@ens-lyon.fr>
* [controls/listbox.c]
Item height is now exactly font height.
Wine listboxes now behave like Windows' when they are
created without WS_VSCROLL but the program subsequently

Have mmioSetBuffer return success (0), so Corel Draw 4
keeps working. (IO is still unbuffered)
Wed May 6 16:57:55 1998 James Juran <jrj120@psu.edu>
* [Makefile.in] [Make.rules.in]
Changed "make clean" to remove `textedit` backup files (*%)

* NtGdiSetVirtualResolution (win32u.@)
|
2009-06-23 15:55:32 +02:00
|
|
|
*
|
|
|
|
* Undocumented on msdn.
|
|
|
|
*
|
|
|
|
* Changes the values of screen size in pixels and millimeters used by
|
|
|
|
* the mapping mode functions.
|
|
|
|
*
|
|
|
|
* PARAMS
|
|
|
|
* hdc [I] Device context
|
|
|
|
* horz_res [I] Width in pixels (equivalent to HORZRES device cap).
|
|
|
|
* vert_res [I] Height in pixels (equivalent to VERTRES device cap).
|
|
|
|
* horz_size [I] Width in mm (equivalent to HORZSIZE device cap).
|
|
|
|
* vert_size [I] Height in mm (equivalent to VERTSIZE device cap).
|
|
|
|
*
|
|
|
|
* RETURNS
|
|
|
|
* TRUE if successful.
|
|
|
|
* FALSE if any (but not all) of the last four params are zero.
|
|
|
|
*
|
|
|
|
* NOTES
|
2021-09-14 21:52:46 +02:00
|
|
|
* This doesn't change the values returned by NtGdiGetDeviceCaps, just the
|
2009-06-23 15:55:32 +02:00
|
|
|
* scaling of the mapping modes.
|
|
|
|
*
|
|
|
|
* Calling with the last four params equal to zero sets the values
|
2021-09-14 21:52:46 +02:00
|
|
|
* back to their defaults obtained by calls to NtGdiGetDeviceCaps.
