Hello,
I have been trying to create a generic dialog box to allow the installing user
to specify members of a (install) created group. The dialog allows the
installer to enter account names into a multiline edit control. These accounts
are then checked by a CustomAction. I also wanted to handle the scenario where
the local group already exists on the target computer. In this instance the
installer is given 3 choices Merge (the new member list with the existing one),
Leave (the existing member this as it is) or Replace (the existing list with
the new one). To do this I provide a ComboBox control on the dialog with the 3
options.
Because this is a generic dialog I tend to use Indirect property references
because it allows me to set the reference and forget without having to pass
values around. I noticed however that there is no easy way to have an indirect
property reference and set the list of ComboBox items.
I think an example would help clarify, given the fragment below:
<UI>
<Dialog Id="dlgIndirectComboBox" Title="Indirect ComboBox Test"
Width="370" Height="270">
<Control Id="cbxChoice" Type="ComboBox" ComboList="yes" X="67"
Y="112" Width="120" Height="18" Indirect="yes" Property="Choice.Value">
<ComboBox Property="Choice.Value">
<ListItem Value="Item 1"/>
<ListItem Value="Item 2"/>
<ListItem Value="Item 3"/>
<ListItem Value="Item 4"/>
</ComboBox>
</Control>
<Control Id="btnNext" Type="PushButton" X="67" Y="142"
Width="56" Height="27" Text="Done">
<Publish Event="EndDialog" Value="Return">1</Publish>
</Control>
</Dialog>
</UI>
This dialog will result in an empty ComboBox list because the <Control>
property is referencing indirectly but in the <ComboBox> element I have no way
of dereferencing it. Is this a bug or is there some syntax of which I am not
aware?
Thanks,
Keith.
