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?
