For the purpose of this example we require four main objects on our form.
| Object | Name | Usage Description |
| Text Box | txtDescription | View and Set CustomTask Description Property |
| Text Box | txtMyProperty | View and Set custom CustomTask MyProperty Property (See Page 1) |
| Command Button | cmdOK | Close Form, saving Properties |
| Command Button | cmdCancel | Close Form, without saving Properties |
The code behind the form is fairly simple. In the Form_Load event you read the properties and
display them on the form. The cmdOK_Click event is used to save the properties back to the CustomTask.
|
Option Explicit
Private Sub Form_Load()
'Get Reference to our CustomTask
Dim oCustomTask As MyCustomTaskUI.CustomTask
Set oCustomTask = oTask.CustomTask
'Set the form object values from our Task/CustomTask properties
txtDescription.Text = oTask.Description
txtMyProperty.Text = oCustomTask.MyProperty
Set oCustomTask = Nothing
End Sub
Private Sub cmdOK_Click()
' Validate Properties
If txtMyProperty.Text = "" Then
MsgBox "Please enter a value for MyProperty", vbCritical, App.Title
Exit Sub
End If
'Get Reference to our CustomTask
Dim oCustomTask As MyCustomTaskUI.CustomTask
Set oCustomTask = oTask.CustomTask
'Save the form settings back to the Task/CustomTask
oTask.Description = txtDescription.Text
oCustomTask.MyProperty = txtMyProperty.Text
Set oCustomTask = Nothing
Unload Me
End Sub
Private Sub cmdCancel_Click()
Unload Me
End Sub

Now you can compile the DLL and Register it through Enterprise Manager.
- Open an existing or new package
- From the Task menu, select Register Custom Task...
- Complete the Register Custom Task dialog and click OK
- Your new CustomTask will now be available from the Tasks toolbar and menu
Whilst this CustomTask does nothing more than display a few message boxes, these in themselves
are useful in determining when the different events are raised. The code for this CustomTask
is available for download below, as a Visual Basic 5 project.
