Using SeaMAX with Visual Basic 6.0
In order to use the SeaMAX library with your Visual Basic program, it will first be
necessary to import the SeaMAX functions using Declare. In each of the example
folders, there exists a file named ‘SeaMAX.bas’ which contains the various type and
function imports.
The following is an example of how to import the various SeaMAX functions into
Visual Basic:
Public Declare Function SeaMaxW32GetCommHandle Lib "CSeaMaxW32.dll" _
(ByVal ptr As Any) As Long
Public Declare Function SeaMaxW32Create Lib "CSeaMaxW32.dll" _

Public Declare Function SeaMaxW32Destroy Lib "CSeaMaxW32.dll" _
(ByVal ptr As Any) As Long
Public Declare Function SeaMaxW32Open Lib "CSeaMaxW32.dll" _
(ByVal ptr As Any, _
ByVal portStr As String) As Long
Public Declare Function SeaMaxW32Close Lib "CSeaMaxW32.dll" _
