Your CAs are all deferred so there is a very small subset of properties
you can get with MsiGetProperty. Parameters are passed to deferred
custom actions in a property called CustomActionData. To set
CustomActionData, you have to use another custom action to set a
property with the same name as the deferred custom action to a string
with the value(s) you want to pass to the custom action. If you have
multiple data items you need to pass, you will need to pass them like a
command line that your CA code will parse
<Property Id="CA_Arguments2" Value="1" />
<!-- This CA sets a property that matches the name of the CA to which we
want to
pass data (CA2). Here we are setting the property with a switch
and an
argument/value pair -->
<CustomAction Id="SetCustomActionDataForCA2" Return="check"
Property="CA2" Value="/switch1 /arg2=value2" />
<!-- CAFunction2 will get the CA2 property by using "CustomActionData"
in the
MsiGetProperty() call and parse the returned string like a command
line
to retrieve the two arguments -->
<CustomAction Id="CA2" Execute="deferred" Return="check"
BinaryKey="mycustom.dll" DllEntry="CAFunction2"
HideTarget="no"/>
<InstallExecuteSequence>
<Custom Action="SetCustomActionDataForCA2" Before="CA2" />
<Custom Action="CA2" After="InstallInitialize" />
</InstallExecuteSequence>
Then in CAFunction2() retrieve CustomActionData with:
MsiGetProperty (hInstall, L"CustomActionData", szActionData,
&dwActionData);
CAFunction2 will have to parse szActionData like a commandline to
retrieve the arguments.
