As far as I am aware you can't pass parameters to custom actions. You can set a property in Wix and use WcaGetProperty to access that.
I use a listbox which is similar like so:
<!--This will be populated via the custom action-->
<Control Id="ListBoxID" Type="ListBox" Property="COMPORT" Width="80" Height="40" X="80" Y="165" Indirect="no">
<ListBox Property="COMPORT">
</ListBox>
</Control>
And in my C++ Custom Action:
hr = WcaGetFormattedProperty(L"COMPORT",&szComport);
ExitOnFailure(hr, "failed to get Com Port");
EDIT:
Ok so I am assuming your ComboBox is something like this:
<Control Id="DummyComboBox" Hidden="yes" Type="ComboBox" Sorted="yes" ComboList="yes" Property="DUMMYPROPERTY" X="65" Y="60" Width="150" Height="18">
<ComboBox Property="DUMMYPROPERTY">
</ComboBox>
Make sure your property is is defined like so(ensure capital letters):
<Property Id="DUMMYPROPERTY" Secure="yes"></Property>
You do not need a custom action to send the value of the property. All you have to do is use:
LPWSTR dummyText = NULL;
hr = WcaGetProperty(L"DUMMYPROPERTY", &dummyText);
ExitOnFailure(hr, "failed to get Dummy Text");
That is for a C++ Custom Action not sure what you are using but a quick google search would tell you the relevant code to use.
