The ActiveGantt control is found in the ActiveGanttVB.ocx file or the ActiveGanttVC.ocx file depending on the language of the component. ActiveGanttVB is the Visual Basic 6.0 file and ActiveGanttVC is the Visual C++ 6.0 (MFC) File. To use this control in your application, you must add the .OCX file to the project. When distributing your application, install the ActiveGanttVB.ocx/ActiveGanttVC.ocx file in the user's Microsoft Windows System or System32 directory and register the control (using regsvr32.exe or a similar tool). XML also requires you to install the following dlls in the end user's windows system32 directory: msxml4.dll (which must be registered using regsvr32.exe or a similar tool) and msxml4r.dll (Windows NT systems) or msxml4a.dll (Windows 9.x systems). ActiveGanttVB also requires the Visual Basic 6.0. SP5 runtime files (which can be found here).
