Yes - to make a COM object in Builder 5 or 6 just do the following:

1. Click File | New, choose the Activex Tab and choose ActiveX Library

2. Click File | Save and save the project - The project name will be the same as the file name.

3. Click File | New - choose the Activex Tab and choose Automation Object. Enter the coClass name - this will be the class name

4. Click View | Type Liabrary.

5. To add a method click the New method button - in the parameters tab you can specify the arguments. Click Refresh when finished

6. Click View | Project Explorer - the code for this new method is in impl.cpp file

7. Goto Project | Options, On the Packages Tab, uncheck the "Build with runtime packages" checkbox, On the Linker Tab, uncheck the "Use dynamic RTL" checkbox

8. Compile the Dll

N.B. Every time you recompile dll you will need to specify new GUID numbers. To do this go to the Type Liabrary and click on each Icon if there is a GUID textbox on the attributes tab - right click on it and choose New GUID - when finished clcik refresh.
