Re: [ros-dev] [ros-diffs] [akhaldi] 67242: [THEMEUI] Add this module for .msstyle file type association. By Lee Schroeder. CORE-5984

Just as a reminder: we can put registry stuff, that is related to a special module, into a separate file together with the module itself now. This one looks a bit like it should go into the the themeui folder.

Re: [ros-dev] [ros-diffs] [cwittich] 67177: [SNDREC32] do not delete objects which are still selected into a DC
by Timo Kreuzer 12 Apr '15

12 Apr '15

Just for the record: it's perfectly fine and safe to do that. They will be kept alive as long as they are selected and will be deleted, once a different object is selected or the DC is deleted.

The Windows implementation of the API is different in user vs kernel-mode. We should probably try to remain compatible.

The comment "# Retrieve the full path to the generated file of the 'freeldr_pe' target" Doesn't explain why it is done. It rather looks like someone is doing something pointless and documenting in a comment that he's doing the pointless. ${CMAKE_CURRENT_BINARY_DIR} should be the "full path to the generated file". So it seems completely pointless to add extra magic to get that file path. Your commit message implies that this change fixes VSSolution builds, but it also doesn't explain it. In fact I don't even understand that sentence. If you don't add a proper comment to that thing, why it is needed, I promise I will have forgotten about this in a year and remove it again. :) Thanks, Timo Am 04.04.2015 um 22:33 schrieb spetreolle(a)svn.reactos.org: > Author: spetreolle > Date: Sat Apr 4 20:33:18 2015 > New Revision: 67053 > > URL: http://svn.reactos.org/svn/reactos?rev=67053&view=rev > Log: > [FREELDR] > In a quest to better registry, > don't break VSSolution builds. > freeldr_pe is not in the same directory and copy doesn't care if you ask to concatenate C:\tomatoes, it already has the first file. > > Modified: > trunk/reactos/boot/freeldr/freeldr/CMakeLists.txt > > Modified: trunk/reactos/boot/freeldr/freeldr/CMakeLists.txt > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/boot/freeldr/freeldr/CMake… > ============================================================================== > --- trunk/reactos/boot/freeldr/freeldr/CMakeLists.txt [iso-8859-1] (original) > +++ trunk/reactos/boot/freeldr/freeldr/CMakeLists.txt [iso-8859-1] Sat Apr 4 20:33:18 2015 > @@ -226,10 +226,13 @@ > add_dependencies(freeldr_pe asm) > add_dependencies(freeldr_pe_dbg asm) > > +# Retrieve the full path to the generated file of the 'freeldr_pe' target > +get_target_property(_freeldr_pe_output_file freeldr_pe LOCATION) > + > concatenate_files( > ${CMAKE_CURRENT_BINARY_DIR}/freeldr.sys > ${CMAKE_CURRENT_BINARY_DIR}/frldr16.bin > - ${CMAKE_CURRENT_BINARY_DIR}/freeldr_pe.dll) > + ${_freeldr_pe_output_file}) > > add_custom_target(freeldr ALL DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/freeldr.sys) > > @@ -240,7 +243,8 @@ > concatenate_files( > ${CMAKE_CURRENT_BINARY_DIR}/setupldr.sys > ${CMAKE_CURRENT_BINARY_DIR}/frldr16.bin > - ${CMAKE_CURRENT_BINARY_DIR}/freeldr_pe.dll) > + ${_freeldr_pe_output_file}) > > add_custom_target(setupldr ALL DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/setupldr.sys) > add_cd_file(TARGET setupldr FILE ${CMAKE_CURRENT_BINARY_DIR}/setupldr.sys DESTINATION loader NO_CAB FOR bootcd regtest) > + > > >
