Automatically writing to SQLdatabase from a text file

Hi!,
Can anybody tell me how to solve this problem. I want to do this using a dll (I want to make it.). When the text file is updating(i.e. editing), database should be updated. There may be several fields related to a table of that database. Delimiter is a comma. when we press Enter key or moving to a new line the record (line) should be saved to the database. Pls. help me in this problem.

What are you using for a front end?

We have a time attendance card reader which, outputs EmpCode, time, etc. to a text file. We want to write a DLL to send those information to a SQLServer database automatically after one input is made to that text file. I don't know whether I want to use an API or I can manage it with simple vb commands. pls! help

No, I meant are you using VB6 or VB.NET or C# or what?

Sorry, I was not be able to understand what you were asked for . I hope to use VB6 but still I did not start coding because I don't know how to track the incoming people.

You can use WaitForSingleObject API to get change notifiation of a file. You use this API for your text file and receive events in any front end tool. According to change you receive you can write code/login for your program.
You need to search more about this API. You can easily get ready made code from the Internet for this.

Thanks
