I've been researching this, and I've found bits and pieces, but not really enough to help me. I can easily create two .asp pages on the net to allow a user to fill in a form, post it to another site that verifies the data and sends back a code (indicating acceptance or one of several errors). The problem is the customer doesn't want it to work quite this way, and the verification company has no problem with our alternative. I am nearly done with a desktop application that is to mimic this process. The data is entered into a database throughout the day. At night, I want to walk through the recordset of all records entered since the last upload. Each record will be sent, the reply received and posted to the database, and the next record processed. No problem so far. What I don't know is how to send and receive from the other site. I've been able to use the Internet Transfer Control to grab a file off the net. I'm pretty sure I understand how to set up the string containing the data. Reciving data I'm less clear on. And I haven't a clue as to how to test it. I tried sending data to a test form, but nothing shows up on the form when I run the program, maybe because I'm not viewing it in a browser from within the program? Do I need to do that to get the communication I need? Clearly I don't have a clear view of how this is to work. I would appreciate any and all help!
