Calling a vb.net dll from a vb6 app

We have a legacy vb6 application and want to expand iots functionality by creating a dll "ITS32.dll" in vb.net and calling it from vb6. I created a .net controlLibrary project and built a beginning dll. I ran it through tlbexp.exe, registered it with regasm.exe, and copied both the ITS32.tlb and ITS32.dll files to the System32 folder. I tried to add the dll to the vb6 project references but it would only accept the tlb. I created a declare statement in the vb6 project to identify the dll sub routine "createForm." My vb6 project has just a command button to call the dll sub. I get an error "Can't find dll entry point createForm in ITS32."

What advice do you have for me?

Well, that kb was very helpful. I copied the example exactly and now get an error message "Cannot create a file when that file already exists." That comes up on the "Set myObject = New TestProj.COMClass1" statement.

OK, I got past that. Now I get the same message on the line that reads "MsgBox myObject.myFunction" which seems weird because myFunction appears when the period is pressed.
