Issues with C++Builder 6 1) ThemeManager is not put on the Include Path for the project automatically. Project > Options > Directories/Conditionals Browse to the install path for ${ThemeManagerInstallPath}\Source and add it to the list. 2) The uxtheme.h file has bug in it. Replace the version that comes with C++Builder 6 with the supplied version. ${CBuilderINstallPath}\Include\uxtheme.h Drop a VirtualExplorerTree component on a form and compile! Enjoy, Jim
