Re: How To create an instance of a Class in Visual Basic

You need to compile this cpp class as a .DLL and then refer this dll in your VB propject.

You are good to go.

Create a dll file using VC++ Win32 Dynamic-Link Library Project type.
Compile the dll and register it in system32.

.CPP and .H files can't be directly referenced fronm VB. compile to .DLL file and then instanceate in VB.

Re: How To create an instance of a Class in Visual Basic

create a DLL.register
to to command prompt and type
c:>regsvr32 <complete path of DLL>

open your vb project. go to project-refrences- add the DLL from the list

now create a object
dim obj as new <nameof DLL.ClassName>

now u can use the function

hope this will work
