c++ - Generate text from MSI made using Wix -

this might sound dummy question, want process parameters given msi file, generated using wix. have developed program visual c++ in vs2010 eg

msiexec /i setup.exe ip="192.168.2.1" port="9999" 

i want access parameters ip , port , write in text file as:

{ "ip":"192.168.2.1", "port":"9999" } 

is possible in wix? if isn't there way this.

i believe there way this, although haven't done myself.

if pass parameter msiexec following:

msiexec /i setup.exe custompropip="192.168.1.1" custompropport="9999" 

then property should set in list of properties msi package can parse. create custom action handle these values , can write file disk.

<binary id="setupca" sourcefile="setupca.ca.dll" /> <customaction id="writefiletodisk" execute="immediate" binarykey="setupca" dllentry="writefiletodisk" /> 

make sure have custom action in install sequences...

<installexecutesequence>   <custom action="writefiletodisk" sequence="2" />   ... </installexecutesequence> 

you need custom action project create setupca.ca.dll. code custom action like:

namespace setupca {     public class customactions     {          [customaction]         public static actionresult writefiletodisk(session session)         {             session.log("begin writefiletodisk"); // useful see when firing through log file created during install /l*vx parameter in msiexec              // work here...             string ipaddress = session["custompropip"];             string ipport = session["custompropport"];              session.log("ending writefiletodisk");             return actionresult.success;         }     } }
