Discussion

Create a VBScript custom action and schedule it to run before the dialogs in the UI sequence.

This VBScript example will create 2 entries in the ComboBox added to a dialog.

PROPNAME is the name of the MSI property used in the ComboBox.
Steps:

• Select a dialog and add the ComboBox Control
• When prompted to specify a property enter: PROPNAME
• In the Installation Designer view, go to the Custom Actions and Sequences view
• Right click on Custom Actions in the middle panel and select New VBScript->Stored in custom action
• In the Common tab -> Sequence section, sequence it to run prior to dialogs in the UI sequence
• In the Script tab use code similar to the example below

Here is some sample VBScript code:

Const msiViewModifyInsertTemporary = 7 

Set oView = Session.Database.OpenView("SELECT * FROM `ComboBox`") 
oView.Execute 

Set objRecord = Session.Installer.CreateRecord(4) 
objRecord.StringData(1) = "PROPNAME" 'MSI Property Name used in Combobox
objRecord.IntegerData(2) = 0  'Entry number in Combobox 0 starting position.
objRecord.StringData(3) = "a" 'Value to be stored in MSI Property
objRecord.StringData(4) = "1" 'Text displayed for Entry

oView.Modify msiViewModifyInsertTemporary, objRecord

objRecord.StringData(1) = "PROPNAME" 'MSI Property Name used in Combobox
objRecord.IntegerData(2) = 1  'Entry number in Combobox
objRecord.StringData(3) = "b" 'Value to be stored in MSI Property
objRecord.StringData(4) = "2" 'Text displayed for Entry

oView.Modify msiViewModifyInsertTemporary, objRecord

?oView.Close
