Immediate custom action is what I am trying to do. I have no need for it to be deferred.

Subject: Re: [WiX-users] using a custom action to read properties from a XML file Are you trying to set properties from a deferred custom action? It looks like it. Only immediate custom actions can set properties. I have an immediate custom action that reads an XML file and sets a bunch of properties. But a deferred custom action isn't going to have access. -- John Merryweather Cooper Senior Software Engineer | Integration Development Group | Continuing Development Jack Henry & Associates, Inc.® | Lenexa, KS 66214 | Ext: 431050 |jocoo...@jackhenry.com -----Original Message----- From: Davis, Jeff [mailto:jda...@nanometrics.com] Sent: Thursday, February 26, 2015 3:33 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] using a custom action to read properties from a XML file I am having a heck of time trying get my mind wrapped around the way to create and use a custom action in my C# Wix Project in Visual Studio 2013. I want to be able to open a specified XML file and return an attribute from a specified key and then use that to initialized a property in the installer and display it in the dialog. Then when installer is run it will write the value to a target XML file to the same key and attribute. In My case I have a MAC_ID Property that is in a UI text box that I want to initialize from a XML file attribute and then write to a new XML file during the install. The write is pretty straightforward since it is built into WIx. But I can't get the read working. I created this Custom Action public class CustomActions { [CustomAction] public static ActionResult ReadXmlValue(Session session) { string fileName = session.CustomActionData["FileName"]; string xmlnode = session.CustomActionData["Node"]; string key = session.CustomActionData["Key"]; XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(fileName); if (xmlDoc.DocumentElement != null) { XmlNodeList nodeList = xmlDoc.DocumentElement.SelectNodes(xmlnode); if (nodeList != null) foreach (XmlNode node in nodeList) { var selectSingleNode = node.SelectSingleNode(key); if (selectSingleNode != null) session["Value"] = selectSingleNode.InnerText; } } return ActionResult.Success; } } My WXS script looks like this <Property Id="MAC_ID" Secure="yes" Value="0"/> <Property Id="MACIDTemplate"> <![CDATA[&&-&&-&&-&&-&&-&&]]> </Property> <CustomAction Id="myActionId" BinaryKey="myAction" DllEntry="ReadXMLValue" Execute="deferred" Return="check" /> <CustomAction Id="SetCustomActionDataValue" Return="check" Property="myActionId" Value="FileName='.\FilesToInstall\Program Files\Zygo\MetroProX\cfg\NewView.IC.xml';Node='\Settings\Section\Section\Section\add';Key='Mac'" /> <CustomAction Id="ReadXMLValue" Property="Value" Value="[MAC_ID]" /> <InstallExecuteSequence> <Custom Action="SetCustomActionDataValue" Before="myActionId">NOT Installed</Custom> <Custom Action="myActionId" Before="InstallFinalize">NOT Installed</Custom> </InstallExecuteSequence> But I don't think I have this setup right?
