Bluescreen on Windows 7 x64

Hello Madshi! On Windows 7 Pro X64 your MCH driver sometimes causes a 0x50 Bluescreen. It is signed with my EV cert (with cross signing) and signed by MS.

Re: SendIpcMessage from service to usersession fails on 32 b

Yes, the 32-bit sender is the problem.

No, I do not have access to the source code. I use v4 linking the static lib files into my executable.

Re: SendIpcMessage from service to usersession fails on 32 b

ist is \RPC Control\mchIpcTEST. If the queue is not available, my SendIpcMessage test executable immediately fails and there is no timeout. just as expected.

Re: ERROR_FILE_NOT_FOUND with Open/Create-GlobalFileMapping

Hi Madshi!

That explains it. What I did not expect was, that you open a session specific mapping instead of failing and setting LastError.

Thanks :)

SendIpcMessage from service to usersession fails on 32 bit

Hi Madshi! I want to send IpcMessages from my system process running in session 0 to my user process running in an input session. It does function, if I use 64-bit processes on 64-bit platform. If I run my 32-bit compilation on a Windows 7 32-bit machine, all IPC calls run into a timeout of approx. ...

ERROR_FILE_NOT_FOUND with Open/Create-GlobalFileMapping

Hi Madshi! When a "global file mapping" is created within a console session (e.g. 1), my system process within session 0 cannot open that mapping. Last error equals 2. The same file mapping can be opened from within the console session by other processes. "Global file mappings" c...

The IPC-queue has no special security descriptor and can be accessed all other (normal) processes. But in Edge the message is not sent and lastError ...
