Do I need to call ReleaseBuffer in this context?

QUESTION

Do I need to call ReleaseBuffer in this context?

Asked 2021-Jan-15 at 16:43

I have been looking here about CSimpleStringT::GetBufferSetLength.

It says:

If you use the pointer returned by GetBufferSetLength to change the string contents, call ReleaseBuffer to update the internal state of CSimpleStringT before you use any other CSimpleStringT methods.

The address returned by GetBufferSetLength may not be valid after the call to ReleaseBuffer because additional CSimpleStringT operations can cause the CSimpleStringT buffer to be reallocated. The buffer is not reassigned if you do not change the length of the CSimpleStringT.

The buffer memory is automatically freed when the CSimpleStringT object is destroyed.

I am actually using CString but given this code:

Short answer: No.

The longer answer is: Don't call GetBuffer/GetBufferSetLength either. Call GetString instead. It will return a pointer to the immutable sequence of characters. This requires a const_cast as well, i.e.

Weird LNK2001 errors after migration to VS2019

Asked 2020-Aug-06 at 18:03

After moving my code from VS2017 to VS2019 I stumbled into strange linker behaviour -- it seems like it references objects from static library that it shouldn't have (which in turn refer to symbols that can't be resolved). Basically, I end up with this:

...

The happens because linker looks for certain symbols (e.g. std::exception::what) that normally get inlined (but not when /clr is in effect) and finds them in random object file of user static library (pulling in all dependencies said object file has). Switching to VS2019 simply changes the order of object files in said library. See details here.

QUESTION

Unresolved external symbol ATL::IAtlMemMgr after upgrading to Visual Studio 2019

Asked 2020-Feb-25 at 07:07

I am currently upgrading our source code from VS2012 to VS2019. One project which uses MFC does not link successfully:

fatal error LNK1120: 4 unresolved externals

error LNK2001: unresolved external symbol "public: void * __cdecl ATL::IAtlMemMgr::Allocate(unsigned __int64)" referenced in function "public: virtual struct ATL::CStringData * __cdecl ATL::CAtlStringMgr::Allocate(int,int)"

error LNK2001: unresolved external symbol "public: void __cdecl ATL::IAtlMemMgr::Free(void *)" referenced in function "public: virtual void __cdecl ATL::CAtlStringMgr::Free(struct ATL::CStringData *)"

error LNK2001: unresolved external symbol "public: void * __cdecl ATL::IAtlMemMgr::Reallocate(void *,unsigned __int64)" referenced in function "public: virtual struct ATL::CStringData * __cdecl ATL::CAtlStringMgr::Reallocate(struct ATL::CStringData *,int,int)"

error LNK2001: unresolved external symbol "public: virtual struct ATL::CStringData * __cdecl ATL::IAtlStringMgr::Reallocate(struct ATL::CStringData *,int,int)"

We are building with Multi-Byte Character Set (MBCS). My first thought was, that we are missing the the mbcs libraries. But as mentioned here, the libraries are installed by default, "when you select MFC and ATL support".

I added atlbase.h in the code and added atls.lib manually as additional dependency, but that did not solve the problem.

How can I figure out which library is missing?

Edit 1: Let's take a look into atlmem.h:

After excluding nearly all source files and commenting out a lot of functionality, I could see that the linker errors are correlated to . Moving to the top of each source files removed the linker errors. However, I am interested to know why compiling with VS2012 gives another behavior compared to VS2019.
