Kernel Question
by ahmet alper parker 23 May '10

23 May '10

Hi all, I am new to this mail group and have a question that probably needs your kind of technical knowledge to answer. I want to use reactos, however, up to its completion, can I use some libraries on windows to replace them? In example, wine libraries can be superseded by original windows libraries if you own them. I want to make the inverse of this simply for security reasons to use a kernel fully opensource and which have a documented api. So can I use ntkrnlos.exe and hal.dll or similar in original windows installations to replace propriety kernel and libraries for security reasons? If yes, which of them should I use, and are they complete to replace them? Also a second question may arise as "the priority of reactos development can be focused on firstly these parts of the project or not?"... Best Regards... Ahmet Alper Parker

Hi! That is for bAnsi:1 to set if ansi. Good job over all!

Shouldn't the LARGE_UNICODE_STRING be used there instead? WBR, Aleksey.

Hi Michael, there is no need to hardcode the messagebox output language to english. In the resource files a string exists for what you're doing: IDS_FINISHEDFIND (probably already loaded into a string in the code somewhere). Thanks, Gregor

Congrats, good stuff Michael :) -----Original Message----- From: ros-diffs-bounces(a)reactos.org [mailto:ros-diffs-bounces@reactos.org] On Behalf Of mjmartin(a)svn.reactos.org Sent: 15 May 2010 20:41 To: ros-diffs(a)reactos.org Subject: [ros-diffs] [mjmartin] 47226: [win32k] - Change the first parameter type from HWND to PWINDOW_OBJECT for IntKillTimer as it makes more sense. Activate IntSetTimer, already done by James. - Add flag TMRF_DELETEPENDING. Destroy timers when this flag is set Author: mjmartin Date: Sat May 15 21:40:33 2010 New Revision: 47226 URL: http://svn.reactos.org/svn/reactos?rev=47226&view=rev Log: [win32k] - Change the first parameter type from HWND to PWINDOW_OBJECT for IntKillTimer as it makes more sense. Activate IntSetTimer, already done by James. - Add flag TMRF_DELETEPENDING. Destroy timers when this flag is set in ProcessTimers to allow any timers that have expired to have the WM_SYSTIMER/WM_TIMER messages posted to message queue before being destroyed. - Fix error in FindTimer, it was always returning a Timer and it needed to return NULL if the specified timer did not exist. - Fix error in PostTimerMessages, need to handle cases where the Window object is NULL which occurs when requesting messages for any window belonging to the thread. - In co_IntPeekMessage, simply call PostTimerMessages to have WM_SYSTIMER/WM_TIMER messages posted for expired timers. Remove call to old timer message handling. - TODO: Code using the old timer implementation needs removed. - Fixes bugs #2393, #3634, #2835. Commit dedicated to JT and Mr. Roboto.
