hi!!! thanks for that suggestion, but the problem is that i dont know the code or the procedure in printing the billing using datareport or crytal report. any suggestions....thank you so much:):):)

Are you asking what the equivalent in MFC of the VB timer event control? AFAIK, MFC has no timer buttons. I Dream of Absolute Zero

You won't get much help with this. Your question doesn't make any sense what-so-ever. Internet connection? Timer? MFC? Button? How does any of this relate to each other and what is it you're trying to do? What's the error? MFC is a Visual C++ thing, not compatible with C#, so I hope you're even in the correct forum!

Our problem is that you have not provided nearly enough details about the file in question. You're going to have to put forth some effort if you expect any reasonable level of help.

a basic version would be: string Password; string Username; ///WHEN THE USER PRESSES OK/// { if (tbUsername.Text == Username && tbPassword.Text == Password) { this.Close() //close the password entry form form1.Enabled = true; //assuming the main form is form1 } else label1.Text = "Username / Password Combination does not match"; } you cannot really copy and paste this, but thats just lazy anyway It should give you an idea of the structure you need to use for your program Regards James
