Hi!
I'm trying to get symbols of a process using "SymGetSymFromAddr64"
but before that, when i try to initialize the whole thing with "SymInitialize(m_processHandle, NULL, TRUE)" I get error code 6 (invalid handle)
which is pretty strange because just before that I get this handle from "CreateProcessA" and I even double-checked that the handle refers to my process
with "GetProcessId"...
does anybody know what could be the problem?
thanks :)
SymInitialize returns "INVALID HANDLE"

Shot in the dark: are you calling SymInitialize on your handle more than once?
no...
Since loading symbols for a given process is an usual thing for a debugger to do, I assume that you're writing some kind of a debugger.
Quoting from the docs:
Does your project follow this guideline?

If the application is a debugger, use the process handle for the process being debugged. Do not use the handle returned by GetCurrentProcess when debugging another process, because calling functions like SymLoadModuleEx can have unexpected results.

yes :(
Is the target process separate from the process in which you call SymInitialize, though? If it is, have you checked that you have debug privileges to the target?

yes, it is a different process and I do have debug privileges (I get them in a LIB component I made, if it makes a difference).
