Well, basically my CA (MyInfCA) installs a file-system driver by calling
InstallHinfSection on the inf. My type 51 CA is currently setting the
"MyInfCA" property to the path of the inf file. This works fine, but I
wasn't sure if it was that "proper" way to do it. I can see that if my CA
needed more information than just the path of the file, type 51 CAs would be
a nuisance, and I would need to resort to something else. In this case, I
guess I would need another DLL CA that would run Immediate that would setup
my values, but how you would accomplish this with the wcautil is a bit
unclear to me. I imagine the same sort of process, in that I would pack all
of the data into a property called "MyInfCA" like I am now but instead do it
by using the WcaWriteStringToCaData, is this correct? And then read it
using the WcaReadStringFromCaData? But what I was not sure on was the
format in which these were added in there. Each of those functions take two
parameters, and the second one is the string. Would you normally just pack
in [name]=[value] pairs in there and then have to break up the strings
myself? Thanks for any insight into this process.

Depends on what you are trying to accomplish. CustomActions that modify
the system state (the reason to create deferred CustomActions) should be
data driven. A property **may** be sufficient to pass data but rarely is
enough. That's why I pointed you at the existing WiX CustomActions. They
handle all the cases that CustomActions need to handle.

Would it be easier to have Type 51 CAs that set a property named the same
as my CA and just retrieve "CustomActionData" from my CA? I guess, what is
the advantage of using wcautil? I realize that there is a TON of
functionality there, but it doesn't seem too intuitive to use with my
minimal Windows Installer experience. It guess I just don't get the process
that I would use wcautil to setup a "data driven MSI" like you mention. I'm
sorry if I'm being obtuse...could you please elaborate? Thanks again for
all of your help/time.

deferred CustomAction chop it up.

Correct me if I'm wrong, but in my case, I just need to call WcaInitialize
in the beginning of my CA, call WcaGetProperty, execute my CA, then call
WcaFinalize?

Yes, there is very little documentation (I've been spending my time fixing
bugs, not explaining how to use it <smile/>). Yes, the SDK directory should
have everything you need. Use the header files that you need.

I see the wcautil.lib in the SDK directory...which header file do I use?
Is the documentation to use wcautil only exist in the header file?

Correct, you have to use CustomActionData. I encourage you to take a look
at the WiX CustomActions. They do all this stuff. Dutil.lib and
Wcautil.lib also has tons of helper functions that make life much easier.

Just to clarify, this means that I can't access any properties from my
CA? And if so, how do you pass a value (CustomActionData?) to a particular
CA in WiX parlance?

Yes. You have to run "in script" (deferred).

*Subject:* [WiX-users] Type 1 Custom Action
Does a type 1 custom action have to be deferred in order to get it to run
AFTER the files have already been installed? It seems when I set it up like
this:
<CustomAction Id="MyCA" BinaryKey="CADll DllEntry="MyCA" />
<InstallExecuteSequence>
<Custom Action="MyCA" After="InstallServices">NOT Installed</Custom>
</InstallExecuteSequence>
When the CA executes, the files haven't been copied yet? Why does this CA
run before the files have been copied?
