App to Server

Hi,

Im building a software that would evenutally let you input your payment details, check with the server, and then let you in, use the app.

Im not quite sure how to do it, add some ip check or something like that, so that i person cannot use the same payment details with other ip's , or using the app if another user is using it with the same payment info.

Im using vb6....so i would need a sql database for that or something?


Please advise :)


Cheers!

i suggest using asp.net and sql database (if you download my book you can learn it fast)
at any rate you can let users set passwords in the database, also you can use cookies to save
on the users pc theire respective details so they log automatically.

im downloading your book.

hopefully i will manage to do something mhmm

download the new one it is much better
