This is wrong, shdocvw will keep being synced as soon as the widl bug is fixed so the resources should stay in the dll root to save whoever is doing the sync the trouble of having to move resources around. -- Steven Edwards "There is one thing stronger than all the armies in the world, and that is an idea whose time has come." - Victor Hugo

This is broken.

Call for participation: ReactOSDbg
by art yerkes 01 Aug '08

01 Aug '08

I've written a shell to use with ReactOS' KDBG that gives a more accurate view of what's going on than other methods available to us (it automatically grabs the module list and loads source files as appropriate, shows locals etc) It's not complete yet, and I'm hoping that others will want to participate in working on it. Therefore, I'm asking those with C# experience on windows who want to get involved to lend a hand in adding the remaining features: - abstract pipe implementation for serial ports and windows named pipes - managing breakpoints - type decoding and struct display using the info available from dbghelp - thread and process listing and focus - a 'watch' window and watchpoints - clipboard interaction - annontated disassembly - general features (bugzilla reporting, automatic interaction with rospaste) To work on this, you don't need to be a wizard, just familiar with windows forms development in C# and willing to learn a thing or two along the way, along with a vm to intstall reactos in and beat up on :-) Some day we'll have everything working with windows style kernel debugging, but until then I feel that a superior stopgap is valuable. -- art yerkes <ayerkes(a)speakeasy.net>

Re: [ros-dev] [ros-diffs] [tkreuzer] 34970: - update KPCR and KIPCR - add KeGetPcr() and update KeGetCurrentProcessorNumber

Kinda curious why you have "unknowns" in a documented structure.
