hii.. i'm new to VB6 and PIC.. i have problem to send data from VB6 to PIC.. actually my project is to measure current temperature and control on/off valve using zigbee module..

The problem is when i click command button in VB6, the PIC doesn't receive the signal. I'm not sure on the coding in VB and PIC. Is it correct to send a character in VB6 to PIC? Can PIC receive a character?

I'm using Zigbee module which transmit data wirelessly from PC to PIC..Is it possible for VB to give command to PIC? i mean wirelessly transmit the command from VB to PIC..

My VB coding:
Private Sub Command1_Click()
MSComm1.Output = ??
End Sub

can anyone give example on the coding..plz help me..
