Author: hbelusca Date: Wed Jun 29 00:38:51 2016 New Revision: 71695 URL: http://svn.reactos.org/svn/reactos?rev=71695&view=rev Log: [SUBST] - Update the resource program description. - Convert to full UNICODE. - Use Win32 functions where possible. - Factor-out the usage of QueryDosDevice into a QuerySubstedDrive function, that returns error codes according to whether the specified drive is a mapped (substed) drive, or is just an existing drive that is not a mapping, or if the drive does not exist. This allows us to detect attempts to use a drive letter that is not a mapped drive, to define a new mapping, and if so we reject such attempt. This fixes CORE-10681 #resolve #comment Fixed with another patch according to my last remark.

Status Meeting (June 2016)
by Aleksey Bragin 28 Jun '16

28 Jun '16

Hello, Let me invite you to the monthly status meeting taking place this Thursday, 30rd of June, 19:00 UTC. IRC service will only be started shortly before the meeting. Your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. Alternative place for the meeting is #reactos-meeting on Freenode. Please send agenda proposals to me before the meeting. My proposal is to discuss 0.4.2 release plans. Regards, Aleksey Bragin

Re: [ros-dev] Pale Moon drops ReactOS support
by Love Nystrom 23 Jun '16

23 Jun '16

Correct me if I'm wrong (Alex?), but isn't the biggest difference between kernel 5.2 and 6.x that 6.x is *paging the kernel* ? (A huge design mistake if you ask me. One I bet will bite MS on the a**. If the kernel gets too fat it needs liposuction, not paging.) IMHO, adding new APIs, while keeping the (non-paging) kernel seems ideal.

IoCompleteRequest frees the IRP so you must not access it afterwards, and use the local variable instead.

I can't debug CoInitialize function
by Yonggang Chen 09 Jun '16

09 Jun '16

Hello developers, After building ReactOS and Rostests successfully, I can't debug CoInitialize function through Visual Studio 2015. It seems Visual Studio thinks I'm using their CoInitialize of Windows kernel. Anybody can help me? Here is the steps I used to compile ReactOS and Rostests: 1. install Build Environment https://reactos.org/wiki/ReactOS_Build_Environment 2. download code to the folder specified when by RosBE during installing code: svn://svn.reactos.org/reactos/trunk/reactos http://svn.reactos.org/reactos/trunk/rostests/ reactOS directory -> E:\Work\reactos rostests directory -> E:\Work\reactos\modules\rostests 3. generate reactos.sln for Visual Stdio (a). Open a Windows DDK/WDK/Visual Studio 2015 command prompt. (b). run the following command in the code root: configure.cmd VSSolution 4. build the huge solutions msbuild reactos.sln /m 5. open the 'ole32_winetest.vcxproj' (E:\Work\reactos\output-VS-i386\modules\rostests\winetests\ole32) Set the command arguments 'ole2', set breakpoint at CoInitialize line, and start beginning by pressing F5, but Visual Studio can't get into CoInitialize funtion Best regards Yonggang Chen

by Alex Ionescu 06 Jun '16

Hi, Implementing MSAHCI would be "more correct" for the system, however MSAHCI also doesn't use STORPORT, it uses ATAPORT, which requires changing our PCIIDEX model to support that. Which I think would put Aman's work out of scope. Now, MSAHCI would be ported to use STORPORT instead, but then we'd essentially be implementing a legacy component on top of a legacy port driver. At least, by implementing STORAHCI on top of STORPORT, we can implement a 'modern' component on top of the legacy port driver. And for this, I would either recommend doing things like implementing StorPortExtendedFunction if Aman can do it -- or if someone can help him, or, avoiding its use with temporary work/arounds, etc. _as long as those workarounds still work in Windows_.

StorPortAllocatePool uses StorPortExtendedFunction, which indeed is not implemented in Win2003. As you can see in WDK samples, 2003's msahci is not a storport miniport driver. Maybe storport wasn't advanced enough for complex drivers back then?

"CX" normally means width, so right = left + cx seems more logical. And SM_XVIRUTALSCREEN is probably 0 most of the time so it would be hard to notice.
