How to create a simple dll in VB. and how to use it with other applications

[VBPhilly]

To create the dll:

1. Start a new project in VB, and select ActiveX DLL for project type.

2. Add a class.

3. Set the classes instancing to 5 - Multiuse or 6 - Globalmultiuse.

4. Give the class a public method.

5. Compile the project.

To instantiate the dll -

with CreateObject:

Dim MyObject As Object
 
Set MyObject = CreateObject ("MyDllProject.MyDllClass") 
 

with project references:

Register the Dll (though, you dont need to if you compiled it on the same machine):

1. Add a reference the dll (project/references).
(note: if you do not see your class in the list, click Browse to select the dll).

Dim MyObject As MyDllProject.MyDllClass
 

Then, you can work with the methods defined publicly for the class:

MyObject.MyMethod()
