I had a look at the source files of the UIExtension, that is, files in wix\src\ext\UIExtension\wixlib
In Common.wxs I see the following line <Binary Id="WixUI_Bmp_Banner" SourceFile="!(wix.WixUIBannerBmp=$(var.bannerBmp))" /> The expression "!(wix.WixUIBannerBmp=$(var.bannerBmp))" seems to be a preprocessor expression, however it is not clear to me what it means. In the preprocessor doc (for V2), an exclamation seem not to be explained there. Could someone point me to some docs on this, please? Jarl -- Jarl Friis Softace ApS Omøgade 8, 2.sal 2100 København Ø.
