[wix-users] how to pass multiple arguments to C# custom action

[KONDURU Pavan]

Hi Ian,

This is how I pass multiple variables to my CAs, hope this helps. It's pretty simple:

In my product.wxs

<CustomAction Id="SetPropertyMyserver" Property="UpdateMyProps" Value="[INSTALLLOCATION],[DISCO_HOSTNAME],[CONFIG_SERVERPORT]" Execute="immediate"/>
<CustomAction Id="UpdateMyProps" BinaryKey="CustomAction" DllEntry="UpdateDiscoProps" Return="check" Execute='deferred' Impersonate='no'/>

<Custom Action="SetPropertyMyserver"      Before="UpdateMyProps"></ Custom>
      <Custom Action="UpdateMyProps"      After="someCA"></Custom>

In my CA code:

String customData = session["CustomActionData"];

            Record record = new Record(1);

            string[] valueArg = customData.Split(',');
            string location = valueArg[0];
            string hostname = valueArg[1];
            string port = valueArg[2];

Subject: [wix-users] how to pass multiple arguments to C# custom action

I am following an example in Nick Ramirez's book Wix 3.6 on how to pass
multiple arguments to a C# custom action.   I can successfully pass a single
argument but not multiple argument.    The end of log file shows
'myDeferredCA' property is correctly defined but
'session.CustomActionData.Values'  is always empty in my custom action.   I
am obviously missing something simple and am hoping someone here can spot my
'hiccup'.   The 'session.CustomActionData.Values' should appear between the
log entries 'Begin myDeferredCA' and 'End myDeferredCA' but the values 'abc123', 'def567' and 'ghi890' never appear between these two log entries.
Can anyone spot what I am doing wrong?

ThanX in advance.

Ian
