Re: [ros-dev] [ros-diffs] [jimtabor] 41250: - Hax-implement NtGdiSetPixelFormat and add a support function UserGethWnd with some code cleanup.

by Timo Kreuzer

This looks like ultra-hax. Can you explain why this should be correct? It would mean DrvSetPixelFormat would be passed a SURFACE rather than a SURFOBJ. jimtabor(a)svn.reactos.org schrieb: > Author: jimtabor > Date: Tue Jun 2 10:50:36 2009 > New Revision: 41250 > > URL: http://svn.reactos.org/svn/reactos?rev=41250&view=rev > Log: > - Hax-implement NtGdiSetPixelFormat and add a support function UserGethWnd with some code cleanup. > > Modified: > [...] > + /* > + Based on some rules!

Re: [ros-dev] [ros-diffs] [dgorbachev] 41284: Remove KeBugCheckWithTf() hack, fix VBEResetHw(). Stefan Ginsberg, bug #4581.

by Aleksey Bragin

He has write access (sginsberg), however he posted that to bugzilla for peer review and comments before committing, not because he lacks time to commit himself. WBR, Aleksey Bragin.

Re: [ros-dev] [ros-diffs] [mjmartin] 41269: - IopCreateDriver: Change MajorFunction routines back to internal function IopInvalidDeviceRequest for ones that were set to NULL in the Drivers DriverEntry. Windows does it and so shall we.

by Alex Ionescu

I must say that I protest to all the recent I/O changes, and in my opinion, they are all wrong and badly researched, and have hacked what was once good code.

Re: [ros-dev] [ros-diffs] [cgutman] 41213: - Export and hackplement NdisSetTimerEx - Implementation is #ifed out currently but I may enable it later - Hopefully somebody can think of a better way to do it than the current code

There's nothing ugly about this -- this is exactly what the field is for.

ReactOS debug on bochs

by Fan Zhang

Hi I download a very early edtion of reactos(0.0.21), I think it would be easy to understand for me. I disable the NDEBUG macro, so I can catch the debug info. By default, I use the /DEBUGPORT=SCREEN, and the log info is printed on the screen. Then I changed to /DEBUGPORT=BOCHS, but there is no any info on the bochs console. Could you tell me how to catch the log on the bochs? Fan Zhang
