How to start woking with Microsoft POS

[Mr.M]

Hi Dw

There is a project in which I'm working on and now it had come to a point where I had to start including the Microsoft Point Of Service and I've already downloaded it and installed ow I must say I'm using windows 7 Home basic and I can't change my OS because I will loose lot of work so I can't install the windows that fully packed with the POS.

If I check the sample codes under Microsoft about how to start calling this feature it show that I have to Inherites the PosCommon under the BillDispenser Class so if I do this it underline the PosCommon I don't know whether I have to load the packs to VB and how am I going to do so so that if I call it on VB it can be linked. If anyone know how can I start working with this please help me.

Thanks.

Thank you but what I was looking for wasn't there and I just managed to sort it last night which I was just suppose to add the Library to the application's reference and then import it to the application. Now the problem I just encounted was to call the BillDispenser to dispense the amount entered so I don't know how can I call it because if I call it, it gave me errors and now I just encounted another errors please see my codes and I've commented where there are errors and I've wrote how I want it to be.
