To use this example, start a new Visual Basic project, place a Text Box and a Command Button on a Form, add the DMCCOM40.BAS module, and type the following code:

Dim m_nController As Integer

Dim m_hDmc As Long

Dim m_nRetCode As Long

Dim m_nResponseLength As Long

Dim m_sResponse As String * 256

Private Sub Command1_Click()

m_nRetCode = DMCCommand(m_hDmc, "TPX", m_sResponse, m_nResponseLength)

Text1.Text = Val(m_sResponse)

End Sub

Private Sub Form_Load()

m_nResponseLength = 256

m_nController = 1

m_nRetCode = DMCOpen(m_nController, 0, m_hDmc)

End Sub

Private Sub Form_Unload(Cancel As Integer)

m_nRetCode = DMCClose(m_hDmc)

End Sub

Where:

‘m_nController’ is the number for the controller in the Galil registry.

‘m_hDmc’ is the DMC handle used to identify the controller. It is returned by DMCOpen. ‘m_nRetCode’ is the return code for the routine.

‘m_nResponseLength’ is the response string length which must be set to the size of the response string. ‘m_sResponse’ is the string containing the controller response to the command.
