I know C and Visual basic programming, how do i create a DLL file that I could use in the VB programs?

I want to experiment on my visual basic program using a link to simplify my codes and that is through using DLL files. I want my DLL files to be made using C/C++ program. After creating a C program, I want to make a DLL file out of it and use this to my VB application.

If you download VB.NET Express (Free download from Microsoft) you can use it to create DLLs

Accessing a C++ DLL from Visual Basic is much easier than from C++. The only task that must be done is to declare the function prototype; Visual Basic will handle everything else. In order to do this, include a code module by clicking Project -%26gt; Add Module -%26gt; Open. In the new module, declare the function prototypes in the following manner:











Declare Sub TestFunc Lib "../testdll_library.dll" ()


Declare Function RetInt Lib "../testdll_library.dll" (ByVal t As Integer) As Integer

















One important note is that all parameters must be passed with the ByVal keyword. This is because Visual Basic always passes parameters ByRef by default. Since C/C++ usually passes by value, this must be specified in the Visual Basic declaration. This is all that is necessary when standard C variable types (int, long, etc.) are used, however complex data types like strings and arrays require more overhead on both the client and DLL sides.
