  1. POWix: Passing Dialogue Control Values to Configurable Merge Modules
    text
    copied!<p>I'm having trouble accomplishing a task with the Wix Toolset. In particular, I have a scenario where I have an MSI that configures an MSM (Configurable Module). The MSI has a custom UI dialogue from which user input is to be used to configure the MSM.</p> <p>When I try to configure the MSM using a hardcoded value for the address property as shown below it works fine and the MSM is configured correctly. (I believe this configuration happens and build-time as opposed to run-time - the issue may lay there.).</p> <p>The problem occurs when I use a custom dialogue to set the value of the address property at installation time (i.e run-time). The configurable module still uses the hardcoded value, rather than the users input. Is the problem because merge module configuration is done during build-time only. Is there a way to pass a value to the merge module from the UI of the main MSI?</p> <p>Here is an over simplified version:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"&gt; &lt;Product Id="cf1d176d-2d57-435e-8e7f-abba14de821c" Language="1033"&gt; &lt;Media Id="1" Cabinet="SemanticEvolution.cab" EmbedCab="yes" /&gt; &lt;Property Id="Address" Value="http://127.0.0.1" /&gt; &lt;Directory Id="TARGETDIR" Name="SourceDir"&gt; &lt;Directory Id="ProgramFilesFolder"&gt; &lt;Directory Id="INSTALLLOCATION" Name="Semantic Evolution"&gt; &lt;Merge Id="MergeModule" Language="1033" SourceFile="Module.msm" DiskId="1"&gt; &lt;ConfigurationData Name="EndpointAddressConfiguration" Value="[Address]" /&gt; &lt;/Merge&gt; &lt;/Directory&gt; &lt;/Directory&gt; &lt;/Directory&gt; &lt;Feature Id="SemanticEvolutionFeatures" Title="Semnatic Evolution" Level="1"&gt; &lt;Feature Id="TestFeature" Title="TestFeature" Level="1"&gt; &lt;MergeRef Id="MergeModule" /&gt; &lt;/Feature&gt; &lt;/Feature&gt; &lt;UI Id="CustomWixUI"&gt; &lt;UIRef Id="WixUI_FeatureTree" /&gt; &lt;DialogRef Id="ConfigurationDlg" /&gt; &lt;Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" Value="ConfigurationDlg"&gt;LicenseAccepted = "1"&lt;/Publish&gt; &lt;Publish Dialog="CustomizeDlg" Control="Back" Event="NewDialog" Value="ConfigurationDlg"&gt;NOT Installed&lt;/Publish&gt; &lt;/UI&gt; &lt;/Product&gt; &lt;/Wix&gt; </code></pre> <p>Here is a snipet of the merge module:</p> <pre><code>&lt;Configuration Name="EndpointAddressConfiguration" Format="Text" /&gt; &lt;Substitution Table="CustomAction" Row="SetEndpointAddress" Column="Target" Value="[=EndpointAddressConfiguration]" /&gt; &lt;CustomAction Id="SetEndpointAddress" Property="EndpointAddress" Value="[EndpointAddress]" /&gt; &lt;InstallExecuteSequence&gt; &lt;Custom Action="SetEndpointAddress" Before="LaunchConditions"&gt;1&lt;/Custom&gt; &lt;/InstallExecuteSequence&gt; </code></pre> <p>Eventually in the merge module the configured property is used as follows:</p> <pre><code>&lt;util:XmlFile Id="EndpointAddress" Action="setValue" ElementPath="/configuration/system.serviceModel/client/endpoint/@address" File="[#Se.Gui.exe.config]" Value="[EndpointAddress]/ApiDataService"/&gt; </code></pre>
