CDrive : Thank you for the tip about Picaxe controllers. I will investigate via their website. And yes, you are very correct when you remark that I like to interface computers with external systems and hardware.
The Velleman VM110 was not of my choosing, but that said it seems a useful board incorporating digital outputs, digital inputs, analogue outputs, analogue inputs plus two PWM output channels. Up to 4 boards can be hooked to the USB simultaneously and individually controlled from VB6.
My problem was getting started with it, since its included CD did not contain dll / VB6 code info. Now thanks to Westconn1 I am well on the track. Inter alia I have now found a comprehensive manual (that supplied with the product was very sparse). For info. I will attach this Velleman manual as .zip. The manual is, if you can find it, freely available on the web. This includes VB code similar to that which Westconn1 kindly found.
