vb6 dll built by Visual Studio 2017

[sch576]

I've found some material to help me get started, but I'm not able to get my .dll built by vs2017 registered/referenced into my vb6 project. The .dll reports the correct export symbols when I urn it through dumpbin.exe, so I think the .dll is "ok", but perhaps there is more I need to do.

Can anyone recommend a go-by for how to connect a VS2017 c++ dll into a vb6 build?

Adding Objects and Controls to an ATL Project is no longer possible it seems.

You may have to look into MFC instead.

Naked flat DLLs are easier and can be used by VB6 programs, but that doesn't to seem to be what you want to do.

Oops, you might need ATL after all: MFC and ATL.

Sorry, it has been over 20 years since I even looked at this.

you need use a regasm tool make *.tlb for vb6

In VB6, press F2(Object Browser), select your DLL and see if you find anything.

When you say your exports are showing up correctly in dumpbin, this leads me to believe you are creating a standard C dll same as stdcall windows api and not an activeX library ?

If this is the case you do not add standard C dlls using the "add references" or "add components" dialogs.

You have to write declare statements for each exported function in them.

A sample dll and vb declares can be found here for various prototypes: http://sandsprite.com/CodeStuff/c_dll_4_vb.zip

if use standard dll by vc++,vb6 can use like:
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (pDst As Any, pSrc As Any, ByVal ByteLen As Long)
you must export by " stdcall"
you also can make com dll(activex dll)
