Serial data string to multiple textboxes

I have tried to read from the serial port and display the string content to 4 textboxes. Problem is when I use Mid, then only the first Textbox displays data, there is nothing on the others. If I jump over the first one then only the second one shows data.


[Private Sub btnVoltage_Click()
Timer1.Enabled = True
MSComm1.Output = ("B9" & vbCr)
txtDataReceived1.Text = Mid(MSComm1.Input, 5, 4)
txtDataReceived2.Text = Mid(MSComm1.Input, 9, 4)
txtDataReceived3.Text = Mid(MSComm1.Input, 13, 4)
txtDataReceived4.Text = Mid(MSComm1.Input, 21, 4)


End Sub]

Thanks

Your first read is clearing the buffer, subsequent reads will be empty.
Put the contents in a string variable first.
Then use the string to fill the textboxes
Try

dim myInput as string
Timer1.Enabled = True
MSComm1.Output = ("B9" & vbCr)
'You should allow at least 50ms delay here, (Sleep Function)
'between write and reads
myInput=MSComm1.Input
txtDataReceived1.Text = Mid(myInput, 5, 4)
txtDataReceived2.Text = Mid(myInput, 9, 4)
txtDataReceived3.Text = Mid(myInput, 13, 4)
txtDataReceived4.Text = Mid(myInput, 21, 4)

Hi
Thanks for your support, I must say that I'm not so good with VB. Probably should I read more books;-
I'll try the code @ work tomorrow.

Thank's
