Why WINAPI works differently in Qt

@JonB No, all that stuff with char's does'nt matter because 'tital' number is wrong, and displaying of all that stuff after with simple char array works well.

because 'tital' number is wrong
As I said above, I think you should print out the relevant
sizeof()s used to calculate that.... -

Vs print that is 28(for my test app), when qt print 40.
That's what one would expect since when you link against Qt your app needs more modules.

Damn i found it!
There is one more function in WinApi with postfix Ex: EnumProcessModulesEx. As it said in documentation of first function(which in my example):
To control whether a 64-bit application enumerates 32-bit modules, 64-bit modules, or both types of modules, use the EnumProcessModulesEx function.
All was needed is add Ex to that function and one more parameter at the end LIST_MODULES_ALL

What :DD
ProcessID was100% correct.
What :DD
?
If you are saying you always pass the current process as
idI would have expected you to useGetCurrentProcessId(). And in that case anyway, https://docs.microsoft.com/en-us/windows/desktop/api/processthreadsapi/nf-processthreadsapi-openprocessIf you are using GetCurrentProcessId as an argument to this function, consider using GetCurrentProcess instead of OpenProcess, for improved performance.
So you might know you're opening the current process, but I don't see anything in your post which indicated that, I assumed it was the id of another process you wanted to examine. Just saying....

Sorry. From my view it seemed like you said that my input of ID was incorrect so function gives "wrong" result.
