[WiX-users] How to create array of properties

[Vuchuru, Surekha (SBT US EXT)]

Hi Everyone,
 
I have a scenario where we get the names of all the subdirectories
inside a particular directory(This is already done using a c++ dll).
This step is being done at the beginning of the installation since the
UI needs to be changed accordingly.
 
The ultimate goal is to copy all those folders to a destination folder
(which has to be done at the end of the installation since the
destination folder is not created until then).
 
The first challenge I am facing is to save the names of all those
subdirectories inside wix code.
 
1) One method is to concatenate all the names with a delimiter and
assign as a single string to a property (which is done by using
MsiSetProperty). But, the real challenge is to split that string in Wix
code (which I have yet to discover)
2) Another method if possible is to create an array of properties and
assign all those names to that array. 
3) Another methood if possible is to create the properties dynamically
from C++ or C# code and assign the values.
 
Note: Total number of subdirectories present may vary from one target
machine to another
 
Please help me proceed with this task further by giving some advice.
 
Thanks and Regards,
Surekha Vuchuru
