Visual Basic Example
A very simple Visual Basic example project is included with the ModSim32 distribution files which
demonstrates how to access/modify data points contained within a ModSim32 document. The example
project simply updates a holding register based on a one second timer and updates a text control on the
form.
To create the project, perform the following steps:
Use the Project Framework to Browse for ModSim32.tlb
In the General Definitions:
Public m_sim As IModSim
In Form Load:
Set m_sim = CreateObject("ModSim32.Document")
On 1 second Timer:
status = m_sim.WritePoint (1, 40100, tick)
if status = 0 Then
tick = tick + 1
End If
status = m_sim.ReadPoint (1, 40100, temp)
if status = 0 Then
text1.text = temp
End If
