Regarding clearcase
 

We have decided to buy the Visual build based on the evaluation copy of the tool. We are actually in need of ClearCase integration into the VisualBuild.
We gathered information that ClearCase could be integrated by providing the DosCommand through RunProgram.
But is there a way to integrate ClearCase like that of CVS.

We would like to provide a custom action for it, but no evaluation version is available for it. We (and a couple customers as well) have tried unsuccessfully so far to make some headway in getting IBM/Rational to provide an eval or temporary license to allow us to incorporate this functionality.

So calling cleartool.exe from a Run Program step would be the way to go. We understand that several customers are integrating ClearCase this way, so it may not be too difficult. If anyone has some samples that might be helpful, please post them at http://www.kinook.com/Forum/forumdisplay.php?forumid=19

ClearCase also supports automation through Com. Attached is a project that shows some of these uses (though the script is not functional, it does perform some interfacing with ClearCase).

The documentation for the automation is:

file:///C:/Program%20Files/Rational/ClearCase/bin/cc_cal.chm

if installed to the default location.
