I\'m making use of the Wix standard dialogs. How do I customise the text of the messages displayed?
For example, in the License Agreement page, I want to change the
The chapter Advanced WiX Topics -> Wix UI Dialog Library -> Customizing Built-in WixUI Dialog Sets in the WiX documentation (wix.chm) has all the information on customising the UI dialogs, including the text. There's also a topic on customising the UI in the WiX tutorial at http://www.tramontana.co.hu/wix/ .
If you do find you need to override more of WiX's default behaviour, the best way to start is to download the sources ( e.g. from http://wix.sourceforge.net/releases/3.5.1030.0/wix35-sources.zip ): all the UI dialogs are in src\ext\UIExtension\wixlib, and will give you an insight into how it works.
Here's how I did it:
Added String elements for each element that I wanted to customise. E.g.
<WixLocalization Culture="en-us" xmlns="http://schemas.microsoft.com/wix/2006/localization">
<String Id="WelcomeEulaDlgLicenseAcceptedCheckBox">I accept the terms of the above Agreement</String>
</WixLocalization>
To determine the Ids of the strings I needed to override, I looked in the WixUI_en-us.wxl file from the Wix source code. In some cases it was helpful to refer to the source code of the individual dialogs to find which strings were used where.
