hi Ghostrider,u seemed to be very experienced in programming, so let's straight to the point, now i'm building a php webbased application, n thinkin about goin to integrate it with an sms feature, got the device, and unfortunately the API provided by the device is written in VB, which is something new for me, my question is, is it possible to call a VB module in php script? i know the most common answer is not possible, because VB is on the server side, and php is on the client side, but i'm sure there is a way, i just dun know how. a brief explanation about my program (pretty simple actually): there is a php page, with the detailed info about a product (type, weight, price, etc). n down below, there is a button "Interested", what i want the program do is, when the user click that button, the php store an information into DB (MySQL), and at the same time, it trigger the VB module, to retrieve the same data and initiate the GSM modem to send sms containing the data. so most likely the data is just goin to be a string sayin "this user is interested in this product , bla bla bla..". i hope u could briefly imagine and eventually can help me with this. many thanks in advance though,
