The following demo is a great example (in my opinion) of how to integrate custom plug-ins in your VB program, by using ActiveX DLLs.
Note: To run the example, it is very important that you read the included readme.txt file and follow the instructions STEP-BY-STEP.
Instructions: Click the link below to download the code. Select 'Save' from the IE popup dialog. Once downloaded, open the .zip file from your local drive using WinZip or a comparable program to view the contents.
