Hi I am using VB6.I have an RFID reader and when searched on google about a particular piece of could which was giving me a hard time, I found a link to this thread. Would you be kind enough to explain to me in some detail what actually happens in the request, anticollison and select card parts with reference to the variables and what is there use. Because altough I got the code working I have trouble documenting it given that I do not know what the variables actually mean....

Any kind of help you provide will be greatly appreciated because this is for my thesis.

Private Sub Command1_Click()
Dim i&, j%, port&, baud&, buf1(200) As Byte, b1 As Byte, s1$
port = cb_ckh.ListIndex + 1
If (port = 0) Then
lb_info.Caption = "Please select COM Port!"
End If
baud = CLng(cb_btl.Text)
If (baud = 0) Then
lb_info.Caption = "Please select Baud rate!"
End If
'Open Port
i = rf_init_com(port, baud)
If (i <> 0) Then
lb_info.Caption = "Open Port Fail!"
Exit Sub
End If
'Request
i = rf_request(0, &H52, j)
If (i <> 0) Then
lb_info.Caption = "Request Fail!"
Exit Sub
End If
'Anticollision
i = rf_anticoll(0, 4, buf1(0), b1)
If (i <> 0) Then
lb_info.Caption = "Anticollision Fail!"
Exit Sub
End If
s1 = ""
For i = 0 To b1 - 1
s1 = s1 & Right("00" & Hex(buf1(i)), 2)
Next i
tx_kh.Text = s1

Hi Barun,

My name is Thushara, I am from Kerala. I am working as a Embedded Engineer in a privare firm here. Now I got a assigment for Interfacing an RFID reader(SL015m) with a Mifare Ultra Light card. I also got the same Visual Basic code, form the company site for interfacing the RFID reader. But, it is not working for me. I don't know why. From your post, I saw that you have told, your code is working well. Can you please help me, friend? I will thankfull to you for a life time. My email id is Removed By Mod.
