Error code:-3 - NTDBG_ACCESS_DENIED

gsorin opened this issue 5 years ago · 3 comments

Hi,
VSDebug helped me a lot.
I have switched from VS2015 to VS2017
When I use the dumpmem command - it returns Error code:-3 - NTDBG_ACCESS_DENIED unless the amount to dump is a few thousands bytes.
Thank you.

Hi,
Can you detail a bit on this ? Also are you sure that the memory range you are trying to dump is valid ?
NTDBG_ACCESS_DENIED is an error code related to memory access rights.

`

// check for valid read address

`

Ok, good to know that it is solved. I've experienced a similar problem but on an older version of VS.
I was going to suggest restarting Visual Studio as a workaround 👍
