using cards.dll

Posted on 1998-09-23
Last Modified: 2010-04-30
I am a "new" VB programmer. Can anyone out there point me to a tutorial on how to use cards.dll or explain it in simple terms? I was in the process of trying to create a
card game and designing a card shuffling function when some one suggested I simply use the cards.dll already on Windows95. I searched the net and found a bunch of stuff
that confused the heck out of me.

If you can be more specific it would help.
First, do you know how call a function from Cards.DLL First?
Second, do you know what functions are available in Cards.DLL?
Third, do you have any idea what am I talking about???? :)

I do not think there is a tutorial on Cards.DLL. However, you have to know how to call a function from a DLL in VB. For a start, is that what you want?

Can you tell me what sort of stuff you found on the network.

It was all familiar to me, but I'll have to study it to figure it all out.
