Visual Basic as client

In Visual Basic, you can connect to the registered object using its program ID (late binding). In Visual Basic 5 or later, you can also use its class name (early binding).

To access a PowerBuilder COM object in Visual Basic:

Do one of the following:
- Declare an object and connect to it using its program ID:
```
Dim EmpObj As Object
Set EmpObj = CreateObject("PB105.employee")
```
- Add a reference to the generated type library for the PowerBuilder COM object to your project, then declare an instance of the object using its class name (in Visual Basic 5 or later):
```
Dim EmpObj As New CoEmployee
```

Check that the connection was established:

Dim response
If EmpObj Is Nothing Then
response = MsgBox("Creating Employee Object", 
      vbOKOnly, "Error")
End If

Access functions or properties of the object:

Dim units, time as Long
Dim DoubleReturn as Double
Dim StringReturn As String

DoubleReturn = EmpObj.f_calcdayavg units, time 
StringReturn = EmpObj.f_teststring
EmpObj.ll_hours = 37

Destroy the object:
```
Set EmpObj = Nothing
```
